This architectural design is called WOPI and was created for web applications that want to integrate with Microsoft Office. That means the architecture was really designed for the CIA to intercept a target's documents saved to Office 365.<sup class="footnote-reference" id="fr-1-1"><a href="#fn-1">1</a></sup> I think good targets would asummably be those <a class="external" href="https://www.ndr.de/fernsehen/sendungen/panorama/aktuell/NSA-targets-the-privacy-conscious,nsa230.html">people who were subscribed to or read</a> <a class="external" href="https://www.linuxjournal.com/content/nsa-linux-journal-extremist-forum-and-its-readers-get-flagged-extra-surveillance">a certain magazine in the early 2010's</a>.</p> <p>As a software design spec, WOPI appears to be robost for online collaborations, but when configured incorrectly, it can become an easy target for interception. I do not have that warm, fuzzy feeling that Russia does not have a backdoor to OnlyOffice, China does not have a backdoor to WPS Office, and the US government does not have a backdoor to Office 365 - so I think I will stay away from those implementations.<sup class="footnote-reference" id="fr-2-1"><a href="#fn-2">2</a></sup> Although, as a US Citizen, I know that there is a due process of law before any sort of surveillance can occur. A judge has to be convinced that there is ample evidence of wrongdoing before any sort of warrant will be granted for surveillance. The other two countries do not seem to afford that legal roadblock.</p> <p>A fourth option of the WOPI protocol is Collabora, which is the original web implementation of LibreOffice. This appeals to me as an alternative to my current OnlyOffice setup. Collabora has <a class="external" href="https://sdk.collaboraonline.com/docs/How_to_integrate.html">great docs</a> and even an example <a class="external" href="https://github.com/CollaboraOnline/collabora-online-sdk-examples//tree/master/webapp/nodejs">low-footprint WOPI server</a>. This will be better than my <a href="/2025-09-08-Only-Office-for-personal-use">Vibe coded OnlyOffice middleware server</a>.</p> <section class="footnotes"> <ol class="footnotes-list"> <li id="fn-1"> <p>This is a totally sarcastic statement, but has a vague realism to it. <a href="#fr-1-1">↩</a></p> </li> <li id="fn-2"> <p>I stay away from Mircrosoft products for other reasons too. Mainly, they are jumbled pieces of software designed for their largest US consumers, <a class="external" href="https://www.youtube.com/watch?v=BKorP55Aqvg">who have no idea what they want in a product</a>. <a href="#fr-2-1">↩</a></p> </li> </ol> </section> 2025-09-08T07:18:03.408003+00:00 2025-09-08T07:18:03.408003+00:00 Andrew Wippler /2025-09-08-only-office-for-personal-use/ <p>Vibe coding is supposedly going to replace actual programmers. I can’t wait for it to go away. Robots have a terrible way of doing things, and they are not very good at writing code. That, however, has not kept me from regularly dabbling with ChatGPT and code generation.</p> <p>Programming is my hobby - not my livelihood. So when it comes to solving an personal issue with code, ChatGPT appeals to me. I am too busy in life to spend hours catching myself up from recent advancements in technology in order to find the right framework, read the docs, and use that knowledge to write good, secure code.</p> <p>I am still not convinced that ChatGPT is smart enough to replace anything of value. In my haste of finding an alternative to Google Docs, I asked ChatGPT to help me code a simple middleware to load OnlyOffice behind authentication.<sup class="footnote-reference" id="fr-1-1"><a href="#fn-1">1</a></sup> OnlyOffice required a JSON Web Token, but their docs were very vague - a vice of all companies that want free fixes from Open Source Software enthusiasts, yet also want money.</p> <p>What was supposed to be a simple task ended up to be a conversaion where ChatGPT said, "Ah, OnlyOffice does x,y,z, but I wrote a,b,c instead. Here, let me fix that for you." When that did not work, ChatGPT would say, "Ah, let's try this instead." To save others from having to spend hours repeating the conversation I had with a robot to generate boilerplate code, let me provide you with the end result.</p> <p>To host and OnlyOffice locally, you need middleware that signs a JSON Web Token, and passes it to OnlyOffice's Document Server for identification. This Document server stores your text and sends it to <del>Vladimir Putin and the Kremlin</del> your storage server after you close your browser window. If anyone wants <del>to send their important documents to dubious destinations</del> to self host OnlyOffice, you may find help with this generated code:</p> <h2 id="middleware-server">Middleware

I had to get used to the new configuration styles and weird doc style of <em>traefik</em>, but suffice to say, I am happy at the end results.</p> <p><em>Traefik</em> ships with SNI, allowing me to snoop the connection and prevent unauthorized access to my file server. (One must have the correct <em>hostname</em> to see my shared photos.) My first action was to replace my edge <em>nginx</em> reverse proxy with <em>traefik</em>. If this was a success, then I would move onto replacing <em>nginx</em> in my k8s cluster. I was surprized that after zero OS tuning changes, <em>traefik</em> was able to serve pages faster for my k8s cluster. I initially thought that <em>traefik</em> would perform marginally slower than <em>nginx</em> due to additional <em>HostSNI</em> checks, but that was totally disproved by the first page load.</p> <p>After switching to <em>traefik</em> inside my k8s cluster, performance improved even more. However, a new problem emerged: I was getting the IPs of my internal traffic logged instead of the real origin IP. While I would not normally care, malicious bots were attempting to brute force my WordPress installations, and I need to block their IPs.</p> <p>I was able to get the <em>X-Forwarded-For</em> header populated with the true ip by enabling the Proxy Protocol on my edge <em>traefik</em>, setting externalTrafficPolicy: Local on my <em>traefik</em> k8s service, and finally telling <em>traefik</em> to accept the <em>proxyProtocol</em> information from the edge server.</p> <pre class="z-code"><code><span class="z-text z-plain"># Edge Router providers.yaml </span><span class="z-text z-plain">... </span><span class="z-text z-plain">tcp: </span><span class="z-text z-plain"> routers: </span><span class="z-text z-plain"> to-web: </span><span class="z-text z-plain"> service: web </span><span class="z-text z-plain"> rule: HostSNIRegexp(`www.andrewwippler.com`, `andrewwippler.com`, ...) </span><span class="z-text z-plain"> entryPoints: </span><span class="z-text z-plain"> - web </span><span class="z-text z-plain"> to-websecure: </span><span class="z-text z-plain"> service: websecure </span><span class="z-text z-plain"> rule: HostSNIRegexp(`www.andrewwippler.com`, `andrewwippler.com`, ...) </span><span class="z-text z-plain"> entryPoints: </span><span class="z-text z-plain"> - websecure </span><span class="z-text z-plain"> tls: </span><span class="z-text z-plain"> passthrough: true </span><span class="z-text z-plain">services: </span><span class="z-text z-plain"> web: </span><span class="z-text z-plain"> loadBalancer: </span><span class="z-text z-plain"> proxyProtocol: </span><span class="z-text z-plain"> version: 2 </span><span class="z-text z-plain"> servers: </span><span class="z-text z-plain"> - ... </span><span class="z-text z-plain"> websecure: </span><span class="z-text z-plain"> loadBalancer: </span><span class="z-text z-plain"> proxyProtocol: </span><span class="z-text z-plain"> version: 2 </span><span class="z-text z-plain"> servers: </span><span class="z-text z-plain"> - ... </span><span class="z-text z-plain">... </span></code></pre> <pre class="z-code"><code><span class="z-text z-plain"># traefik k8s deployment and service </span><span class="z-text z-plain"># missing service account definition and CRDs </span><span class="z-text z-plain">apiVersion: apps/v1 </span><span class="z-text z-plain">kind: Deployment </span><span class="z-text z-plain">metadata: </span><span class="z-text z-plain"> name: traefik </span><span class="z-text z-plain">spec: </span><span class="z-text z-plain"> replicas: 3 #&lt;-- one for each of my nodes, for failover </span><span class="z-text z-plain"> strategy: #&lt;-- forces k8s to update pods on configuration change </span><span class="z-text z-plain"> rollingUpdate: </span><span class="z-text z-plain"> maxSurge: 1 </span><span class="z-text z-plain"> maxUnavailable: 1 </span><span class="z-text z-plain"> type: RollingUpdate </span><span class="z-text z-plain"> selector: </span><span class="z-text z-plain"> matchLabels: </span><span class="z-text z-plain"> app: traefik </span><span class="z-text z-plain"> template: </span><span class="z-text z-plain"> metadata: </span><span class="z-text z-plain"> labels: </span><span class="z-text z-plain"> app: traefik </span><span class="z-text z-plain"> spec: </span><span class="z-text z-plain"> affinity: #&lt;-- one replica per node </span><span class="z-text z-plain"> podAntiAffinity: </span><span class="z-text z-plain"> requiredDuringSchedulingIgnoredDuringExecution: </span><span class="z-text z-plain"> - labelSelector: </span><span class="z-text z-plain"> matchExpressions: </span><span class="z-text z-plain"> - key: app </span><span class="z-text z-plain"> operator: In </span><span class="z-text z-plain"> values: </span><span class="z-text z-plain"> - traefik </span><span class="z-text z-plain"> topologyKey: &quot;kubernetes.io/hostname&quot;

While all of the elite programmers, cool kids, and CS grads are talking languages such as Go and Erlang - how to do tracing, performance testing, and the like - it seems very juvenile for me to write about PHP.</p> <p>PHP is a language made specifically for the web. It is the first web language I learned after HTML 4/CSS. I learned it because it was easy. The syntax was easy, the variables - easy, running it - easy; however, when something broke, it was difficult as a beginner to troubleshoot. I would spend several hours looking at the code I just wrote only to find out I missed a semicolon or quote. This post is several things I wish I knew when I started with PHP.</p> <h2 id="white-pages">White Pages</h2> <p>When coding in PHP, you will often find a blank white page with nothing printed on it. This means PHP was unable to complete the page construction due to an error in the code.</p> <p>In the early days, PHP had error reporting on by default. Rather than being greeted with a white page on error, you would have the error code presented to you - making it very obvious where the issue is located. Due to novice SysAdmins/Devs who would leave error reporting on in production, PHP maintainers switched this default behavior to off.</p> <p>I find it easier to debug code when the process goes like:</p> <ol> <li>Write code</li> <li>Load page in browser</li> <li>See error message</li> <li>Fix code</li> <li>Repeat</li> </ol> <p>With current defaults, the workflow is as follows:</p> <ol> <li>Write code</li> <li>Load page in browser</li> <li>Open terminal</li> <li>Tail log file</li> <li>See error message</li> <li>Fix code</li> <li>Repeat</li> </ol> <p>While it is only 2 steps more, consider the time wasted trying to find the correct path to the log file. Would it be in nginx's error log file or would it be in the www fpm pool's www-error.log?</p> <h2 id="application-deployment">Application deployment</h2> <p>It is 2017, if you have not tried nginx as your webserver, you are missing out. I have wrote an article on<a class="external" href="http://andrewwippler.com/2016/04/26/linux-nginx-mysql-5-7-and-php-7-lemp-on-aws-with-free-ssl/"> how to deploy a LEMP stack</a> which you should read. Not only is nginx syntax easier to read, it is much easier to tune, and it forces you to use PHP-FPM which is currently the best way to run PHP applications. In the early days, PHP was run as a process of the apache web server. This made applications spawn a new apache worker to run simple PHP code.</p> <p>If your application code and web server reside on the same server, make sure PHP is listening as a unix socket. Why should the flow of bits go through the network stack back to the same machine? This is inefficient.</p> <h3 id="setting-up-php-fpm">Setting up PHP-FPM</h3> <p>On RHEL/Fedora/CentOS PHP-FPM settings are in <code>/etc/php-fpm.d/&lt;pool name&gt;.conf</code> To set up a unix socket, find the listen directive and change it to a file path - such as /var/run/php.sock. You will then have to alter the listen.user, listen.group, and listen.mode settings. These three settings determine which level of access your user will have to the PHP application socket. For instance if the listen.user is andrew, your web server will have to be running as andrew. The andrew user would also need access to the directory on your system with the application code (typically <code>/var/www/html/&lt;application name&gt;/</code>).</p> <p>In the old days before git, many web developers ssh'ed into a box and edited the same code base. The same group would be applied to all users ssh'ing in and the application directory would have the group own the folder like the example below.</p> <pre class="z-code"><code><span class="z-text z-plain">drwxrws---. 2 nginx webadmins 4096 Dec 22 07:38 /var/www/html </span></code></pre> <p>Users would then have to be the nginx user or a member of the webadmins group to access this folder - all other access was prohibited. Before cloud computing, many people shared the same server and groups would differentiate who had access to what.</p> <p>The listen.group directive in the PHP-FPM pool is which group you want to be able to access the socket. The listen.mode determines which access the user, group, and other have to this socket. Permissions of 0444 would prevent anything being written to the PHP socket.</p> <h2 id="know-thy-logs">Know thy logs</h2> <p>Production machines should not be writing logs to disks that are local. Production machines should have a separate NIC that is connected to an internal network - over which logs should be sent. The separate NIC is there to ensure your logs are not interfering with web traffic. Below are the 4 logs of PHP applications.</p> <h3 id="nginx-apache-access-log">nginx/apache access.log</h3> <p>The access log shows what people are trying to access on your server. Log formats can be adjusted, but I have found the default works quite well. The default format shows the originating IP, the HTTP status code, time accessed, the URI being accessed, and other useful information. The access log is not generally used in debugging, but it does give some great insights as to who is visiting your application.</p> <h3 id="nginx-apache-error-log">nginx/apache error.log</h3> <p>The error log contains the errors your application presents to your web server. If your application produces a T_STRING php error, the line will show up here. This log is your friend. You must understand everything he says and fix it. :)</p> <h3 id="php-fpm-pool-error-log">&lt;php-fpm pool&gt;-error.log</h3> <p>This log informs you about the stability of your process workers. If you restart them, it logs that action here. If there is something wrong with your compiled version of PHP, it will show up here.</p> <h3 id="php-fpm-pool-slow-log">&lt;php-fpm pool&gt;-slow.log</h3> <p>The slow log is also your friend, but it has to be enabled and configured first. The slow log is set by enabling it in the PHP-FPM pool (<code>slowlog = /path/to/$pool-slow.log</code>) and configuring a threshold of when it should begin logging (<code>request_slowlog_timeout = 0</code>).

In this case the issue stemmed from the <code>nginx-helper</code> plugin. I had manually set the two multisite settings in the nginx configuration and no longer needed this helper plugin.

Most find it helpful to use syntax highlighting (something I was not aware of when I first started) as well as an IDE that has PHP linting, code completion, and other features built-in. You may also want to look into using <code>pm = static</code> and manually determining how many child workers FPM should have. Another option is to enable the <code>/status</code> page and configuring your monitoring application to poll that URL. All of these settings are found and set in the PHP pool's config file.</p> 2016-12-09T14:00:00+00:00 2016-12-09T14:00:00+00:00 Andrew Wippler /2016-12-09-openstack-certification/ <p>On Dec 20th, I am scheduled to take my COA exam. <a class="external" href="http://www.openstack.org/coa/requirements">From the exam requirements page</a>, it appears to be a somewhat moderately difficult exam. The few points I need work on are heat templates and swift object administration. A few things I know about the exam are what are <a class="external" href="https://www.youtube.com/results?search_query=pass+openstack+COA">publicly available via YouTube videos</a> of the OpenStack summit sessions.</p> <p>One of my troubles of studying for exams is creating content to test myself on the objectives of the exam. I look at the requirements and say to myself, "I know that," and nothing gets written for that aspect. One thing I have done in the past is to search Github for exam prep questions. One I have found for OpenStack is <a class="external" href="https://github.com/AJNOURI/COA">AJNOURI/COA</a>. He also made a nifty <a class="external" href="https://ajnouri.github.io/coa/">website</a> for his test prep questions.</p> <p>A key aspect that has helped me pass all of my open book exams is to recall the locations of my troubled areas.

Of the articles I read, all seem to complain about the instability of docker, the docker ecosystem, and they lament persistent storage. While I have not run docker in production for a lengthy amount of time, I can determine these issues are from operator error and are not entirely docker's fault.</p> <p>One article I read came out and boldly said that docker created a new file system in one year and it is not humanly possible to have created one in such a short amount of time. I think this article writer has never heard of the DevOps philosophy nor the minimum viability product (MVP). Basically, you do not need 100% of the features to have a working product. This makes it clearly possible to build a single file system - though not have all of the features - within a short time frame. It is also noted that a year in this development process, a second file system was created. Just like in real life, if you wait to ship a product with 100% of the features, you will never ship the product.</p> <p>If you are losing data due to not properly mounting the volumes to a HA storage network (such as GlusterFS or DRBD) - you deserve to have lost the data. I know what it is like to lose 50TB of unique data due to a failed storage device, no current backups, and the shame and cost of having to send it over to DriveSavers (which they are!) for recovery. That is a painful experience and not worth repeating. If you do the same thing and expect different results, the issue lies with the operator and not the tool. Drastic changes were made when loss occurred including developing a new backup solution and having 1-to-1 replication of the data. It has also fine grained a permanent memory in my subsystem to not let that happen ever again.</p> <p>Personally, I think running docker in a public cloud is a waste of company resources - there is no price difference between a VM and 1 docker image on AWS' EC2 container platform of the same capacity. Even if you spun up an Atomic Host or similar, you still have to deal with networking constraints for your file storage. This is something best handled in house as you can scale your network infrastructure to match your workload.</p> <p>The most important factor in all of this fuss about docker is that it is open source software. If you do not have the capacity to find flaws, make patches, and submit those patches for review to upstream, you are better off using a proprietary product that does not have such needs. Again, the issue lies in the operators and not the tools.</p> 2016-11-11T14:00:00+00:00 2016-11-11T14:00:00+00:00 Andrew Wippler /2016-11-11-website-protection/ <p>There are several factors that go into securing a web application. Most are second nature to seasoned system administrators, but it is still too common to talk to someone who does not know how to properly secure a web application. Here is the common checklist I go through when I determine if a website is secured.</p> <ul> <li>Is it using a firewall?</li> <li>Am I using unique passwords that are over 20 characters?</li> <li>Are passwords required to alter data?</li> <li>Is my codebase up to date?</li> <li>Are the only public facing ports HTTP and HTTPS?</li> <li>Do I protect data in transit from the user to my site by enforcing HTTPS?</li> <li>Do I protect data from my website to the database with SSL?</li> <li>Is my database only accessible to my application?</li> <li>Do I have my database and application on different servers?</li> <li>Can a malicious user drop/delete/alter data from my database from a form/switch/button that is publicly accessible on my website or do they need to login to perform that operation?</li> <li>Do I have separate connections and users to the database for writing and reading data?</li> <li>Do I rate limit connections via web application firewall or utility like fail2ban?</li> <li>Am I reading and blocking malicious inputs via web application firewall or mod_security?</li> <li>Can anyone brute force a login or am I blocking it after 5 tries?</li> </ul> 2016-10-21T14:00:00+00:00 2016-10-21T14:00:00+00:00 Andrew Wippler /2016-10-21-deploying-puppet-open-source/ <p><strong>Update: (5/28/17)</strong> yes, there is the puppet/r10k which supercedes the zack/r10k. While you are free to deviate from the article in your own environment, the below steps still work as intended. I will have to update this article as well as explain why having r10k and dynamic environments is a good idea.</p> <p>In this guide we will go over best practices to deploy Puppet Open Source using the recommended workflow (r10k), PuppetDB, and the foreman. You can deploy Puppet server on any of their supported *nix distributions. In this tutorial we will assume it to be on CentOS 7 as this seems to have the best support.</p> <p>The overall scope of this tutorial is as follows:</p> <ol> <li>Set up foreman</li> <li>Set up a control repo</li> <li>Download r10k module</li> <li>Run puppet apply on r10k.pp (with web hook)</li> <li>Set up PuppetDB</li> </ol> <p>Foreman installation is the easiest. Just head over to <a class="external" href="https://www.theforeman.org/manuals/1.12/index.html#2.1Installation">https://www.theforeman.org/manuals/1.12/index.html#2.1Installation</a>, select CentOS 7 and follow the 5 easy steps. The defaults are fine, but if you want to provision hosts on Digital Ocean or Amazon Web Services, be sure to use interactive mode (the <code>-i</code> switch on <code>foreman-installer</code>) and configure those settings. You can also re-run the installer as it will remember previous settings. Since the foreman installer is built with puppet, it will not override any settings - just enforce them. This allows running the <code>foreman-installer</code> on an already provisioned <code>puppetserver</code> non-destructive.</p> <p>The control repo is the next step and is also very easy to perform. Just fork the <a class="external" href="https://github.com/puppetlabs/control-repo">Puppet control-repo</a> to a local git repository or private git location. Instructions are included in the repo on how to set it up on a gitlab server.</p> <p>Once <code>foreman</code> has installed completely, install the <code>zack/r10k</code> module to manage r10k by running <code>puppet module install zack-r10k</code>. This downloads all prerequisites for managing r10k and getting the ball rolling on a great DevOps practice. You will then need to apply a new puppet manifest to manage r10k's installation and configuration. You can do that by creating <code>r10k-install.pp</code> with the following contents:</p> <pre class="z-code"><code><span class="z-text z-plain">#Fixes Puppet 4 path for webhook </span><span class="z-text z-plain">file {&#39;/usr/local/bin/puppet&#39;: </span><span class="z-text z-plain"> ensure =&gt; link, </span><span class="z-text z-plain"> target =&gt; &#39;/opt/puppetlabs/bin/puppet&#39;, </span><span class="z-text z-plain">} </span><span class="z-text z-plain"> </span><span class="z-text z-plain">class { &#39;r10k&#39;: </span><span class="z-text z-plain"> # Point this to your forked control-repo </span><span class="z-text z-plain"> remote =&gt; &#39;git@localgitrepo:puppet/control-repo.git&#39;, </span><span class="z-text z-plain"> # You will need to create this ssh-key pair </span><span class="z-text z-plain"> git_settings =&gt; { </span><span class="z-text z-plain"> &#39;private_key&#39; =&gt; &#39;/etc/puppetlabs/puppetserver/r10k&#39;, </span><span class="z-text z-plain"> } </span><span class="z-text z-plain">} </span><span class="z-text z-plain"> </span><span class="z-text z-plain"># Instead of running via mco, run r10k directly </span><span class="z-text z-plain">class {&#39;r10k::webhook::config&#39;: </span><span class="z-text z-plain"> use_mcollective =&gt; false, </span><span class="z-text z-plain"> # replace the file names with the correct cert names </span><span class="z-text z-plain"> public_key_path =&gt; &#39;/etc/puppetlabs/puppet/ssl/certs/puppet.example.org.pem&#39;, </span><span class="z-text z-plain"> private_key_path =&gt; &#39;/etc/puppetlabs/puppet/ssl/private_keys/puppet.example.org.pem&#39;, </span><span class="z-text z-plain">} </span><span class="z-text z-plain"> </span><span class="z-text z-plain"># this exposes https://0.0.0.0:8088/payload for git webhooks </span><span class="z-text z-plain">class {&#39;r10k::webhook&#39;: </span><span class="z-text z-plain"> use_mcollective =&gt; false, </span><span class="z-text z-plain"> user =&gt; &#39;root&#39;, </span><span class="z-text z-plain"> group =&gt; &#39;0&#39;, </span><span class="z-text z-plain"> require =&gt; Class[&#39;r10k::webhook::config&#39;], </span><span class="z-text z-plain">} </span></code></pre> <p>With that file saved, run <code>puppet apply r10k.pp</code>. This will enforce and set up r10k.</p> <p>One of the last things I do on a new Puppet 4 installation is set up PuppetDB. PuppetDB is used to collect exported resources and return them to nodes that want them (i.e. the built-in nagios plugin). By now you should already have puppet installed and working without error. To add PuppetDB into the environment, it is as simple as editing the <code>Puppetfile</code> in your control repo to have <code>mod 'puppetlabs/puppetdb'</code> and <a class="external" href="https://forge.puppet.com/puppetlabs/puppetdb/dependencies">matching the dependencies for the PuppetDB module</a>. Next edit your <code>site.pp</code> manifest to include the following:</p> <pre class="z-code"><code><span class="z-text z-plain">node &#39;puppet&#39; { </span><span class="z-text z-plain"> # Configure puppetdb and its underlying database </span><span class="z-text z-plain"> class { &#39;puppetdb&#39;: } </span><span class="z-text z-plain"> # Configure the Puppet master to use puppetdb </span><span class="z-text z-plain"> class { &#39;puppetdb::master::config&#39;: } </span><span class="z-text z-plain"> </span><span class="z-text z-plain"> # ... r10k stuff should go here. Make sure to add the module and its dependencies to the Puppetfile! </span><span class="z-text z-plain">} </span></code></pre> <p>On the next puppet run, you should have a solid Puppet environment. Your next step would be to set up the git webhook. This is so that every time you push changes to the repo, r10k updates them on your puppet master.

While under DDoS, a victim's server (or servers) is under high load and cannot complete all requests that are requested by it. Basically, a DDoS victim is someone the attacker wants silenced on the internet. In order to send a DDoS of that magnitude, the attacker has to have control over many computers - a botnet. It is believed that this attack originated from over 150,000 computers in the IoT category (smart TVs, refrigerators, thermostats, etc.). Due to their poor default security, the IoT devices are easy targets for hackers who intend on adding them to their botnets. <a class="external" href="http://arstechnica.com/security/2016/09/linux-kernel-security-needs-fixing/">A recent article on Ars Technica points out the current issues with IoT and Linux kernel security</a>, but with most articles of this nature, provides no clear cut solution to the problem we are experiencing. Below are my thoughts to this current situation and how it may be resolved.</p> <p>We need a governing body to issue a seal of approval for IoT and anything that is compiled with the Linux kernel. Then we, as consumers, must use, buy, and encourage others to buy from the companies that have this seal. The governing body should ensure each company seeking the seal comply with the following criteria:</p> <ol> <li>Every new device created and sent to market has a minimum of 5 years worth of bi-monthly security patches and updates since the day of release to the public.</li> <li>In the event the company goes bankrupt, dissolves, or cannot support any older product they have released in the past 5 years, the company must provide schematics, instructions, or software that open source enthusiasts can recreate, patch, or upgrade the legacy product.</li> <li>No known vulnerability must be willingly left unpatched.</li> <li>When a CVE is identified on a company's product, a test case must be created and run on that code base for every future release.</li> <li>A notification service must be in place when new updates are released and must be available in RSS or email form.</li> <li>Automatic updates should occur over HTTPS</li> <li>Backdoors, admin terminals, etc. should require a physical connector be applied on the device in order to grant access.</li> </ol> <p>For a potential company to get this approval, it may seem like an arduous task to get all the controls in place; however, by applying DevOps methodologies, these tasks can be a simple feat. This would require the governing body to not only enforce the list, but also have the training available to comply to this list. For this reason, I suggest the Linux Foundation to become this governing body and issue out seals of approval.</p> 2016-09-30T13:00:00+00:00 2016-09-30T13:00:00+00:00 Andrew Wippler /2016-09-30-first-puppet-module-published/ <p>I completed my first public module for puppet and submitted it to the puppet forge. It seems too simple to compile into a build and submit it to the forge; however, I made it public for these reasons:</p> <ol> <li>I needed experience with puppet code testing. This helped me at the most basic level.</li> <li>I felt like someone else could benefit from the code - even if it is one person.</li> <li>I wanted to do it.</li> </ol> <p>Still, the code seems too juvenile to be submitted to the forge. All it does is take the hostname of a Digital Ocean droplet and submit its IP address as a new DNS record inside of Digital Ocean DNS. The code is <a class="external" href="https://github.com/andrewwippler/do_dns">located here</a>.</p> <p>I almost want to follow up with this and develop my duplicity module into reusable code for the community.</p> 2016-09-02T14:00:00+00:00 2016-09-02T14:00:00+00:00 Andrew Wippler /2016-09-02-provisioning-vms-with-cloud-init/ <p>One of the easiest ways to deploy a virtual machine in oVirt is first to install the OS then turn it into a template. This will allow you to copy that template to deploy new instances. One mundane task after a new template is copied to a new instance is logging in, changing the IP, setting the hostname, setting up Puppet, running puppet, etc. <code>cloud-init</code> is the tool designed to fix that mundane task process by allowing those steps to be automated. oVirt/RHEV (as well as OpenStack, AWS, and others) allow you to pass in user data which is then supplied to <code>cloud-init</code> after the template is copied over and turned on. This allows for scripting on the new VM - easing deployment.</p> <p>For my environment, I wanted a CentOS 7 template. To have that, I must first install CentOS on a new VM and seal it (Windows calls this Sysprep). Before I seal it, I must install <code>cloud-init</code> and any other tools I might use for deployment - such as <code>puppet</code>. Here are the steps to obtain just that:</p> <p>* Install CentOS 7.2 Minimal on any new VM. Ensure to have LVM partitioning as you may want to extend the disk later. I have found that 10 GB is a good starting size.</p> <p>* Install your base files - things you cannot live without (i.e. <code>vim</code>,<code>puppet</code>, etc).</p> <p>* Seal the VM <a class="external" href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.5/html/Administration_Guide/sect-Sealing_Virtual_Machines_in_Preparation_for_Deployment_as_Templates.html#sect-Sealing_a_Linux_Virtual_Machine_for_Deployment_as_a_Template">per RedHat instructions</a>. I suggest following the instructions for sysunconfig:</p> <ol> <li> <p>Log in to the virtual machine.</p> </li> <li> <p>Remove ssh host keys:</p> <pre class="z-code"><code><span class="z-text z-plain"># rm -rf /etc/ssh/ssh_host_* </span></code></pre> </li> <li> <p>Set <code>HOSTNAME=localhost.localdomain</code> in <code>/etc/sysconfig/network</code> for Red Hat Enterprise Linux 6/CentOS 6 or <code>/etc/hostname</code> for Red Hat Enterprise Linux 7/CentOS 7.</p> </li> <li> <p>Remove the <code>HWADDR</code> line and <code>UUID</code> line from <code>/etc/sysconfig/network-scripts/ifcfg-eth*</code>.</p> </li> <li> <p>Optionally, delete all the logs from <code>/var/log</code> and build logs from <code>/root</code>.</p> </li> <li> <p>Run <code>sys-unconfig</code></p> </li> </ol> <p><code>sys-unconfig</code> will turn off the VM when it is completed. When it is turned off, right click the VM and select copy to template.</p> 2016-08-12T15:00:18+00:00 2016-08-12T15:00:18+00:00 Andrew Wippler /2016-08-12-avoiding-catastrophic-failure/ <p>You may have already heard the news about <a class="external" href="http://www.nbcnews.com/news/us-news/delta-system-outage-triggers-delays-worldwide-n625141">Delta Airlines catastrophic failure</a>. <a class="external" href="http://arstechnica.com/business/2016/08/data-center-disaster-disrupts-delta-airlines/">Ars Technica reports</a> the true cause of the failure - <a class="external" href="http://www.flyertalk.com/forum/27032000-post135.html">routine maintenance of the power generators</a>. While it may be a little presumptuous or high on the bragging scale to have only one datacenter to house your entire infrastructure - this is not the best method. The blame is often placed on the IT personnel when computer systems go down, but in this case the error is shared. There was a maintenance individual who did not spot the potential of a fire, there is the building planning committee that placed the power sources too close together, there is the IT budgeting team that did not have an off-site solution, and there is the CTO misinformed on the infrastructure needs of a worldwide company. A catastrophic failure is anything that damages a company's reputation.</p> <p>I can understand the single point of failure - it is often found in SMB/non-profit environments. The single point of failure happening is marginal at best. This causes it to be overlooked many times over as some will hope it never comes to encountering that scenario. Budgetary constraints are often the first road block, the second being time to implement, the third being the internal security practices of customer data, and the fourth being the time to restore after a catastrophic failure is less than 24 hours - these also minimizes the single point of failure in our minds. We so often minimize the single point of failure to where it loses its place as #1 concern to #100 on "do someday task."</p> <p>We live in the best computer age right now. Catastrophic failures can be avoided. Here are a few ways to prevent catastrophic failures.</p> <ol> <li>Keep up-to-date on current software trends/best practices.</li> <li>Don't keep all of your eggs in one basket. Keep your services separated.</li> <li>Research and obtain certifications relevant to IT, but not necessarily directly related to your field of work. For instance, a network engineer achieving a Linux certification or a SysAdmin getting a CCNA.</li> <li>Get IT audited. If the audit returns no suggestions, get audited by another company within 3 months.</li> <li>Simulate all the disaster recovery scenarios twice every 5 years. Have different managers perform the restore, meet with their findings (how long it takes, what is needed, budget), and record it in documentation.</li> <li>Ease the restore time by having everything in a configuration management engine (Like Puppet, Chef, Anisble, Salt, and others)</li> <li>Reward IT employees if there have been no service disruptions in the past month. Yes, do it regularly. It can be as simple as a thank-you card, gift card, or the ability to leave early one day in the next week.</li> </ol> <p>I do not know Delta Airlines' software/hardware stack, but I would estimate that they have at least a database and a front end that communicates with the database. With that estimation, it would be easy to set up an AWS environment where an auto scaling group contained a replica of the datacenter database. Even if it required a manual switch from on-premise to the cloud database, the total downtime would have been less than 20 minutes (10-15 minutes for the IT manager to find the wiki entry and delegate the task to the right guy, 5 minutes for DNS propagation). Maintaining something like this would be around $500/month for the AWS VPN connection and database servers. If they go this route or not time will only tell. One thing is certain, change is going to be made to their infrastructure.</p> 2016-08-05T14:00:00+00:00 2016-08-05T14:00:00+00:00 Andrew Wippler /2016-08-05-common-problems-with-web-developers-configuring-lamplemp/ <p>I am a SysAdmin who likes to code. I would say I know a fair amount of web developing, but do not understand it like a web developer uunderstands it. I think the reverse is true as well - web developers know how to set up a LAMP/LAMP stack, but they do not understand it as well as SysAdmin might understand it.</p> <p>To be a successful SysAdmin, you need to relearn your field every 3-5 years. New versions of software come out, new OSes, new features, new methods, and new ideas come out every several months. It takes somebody dedicated to read news blogs, mailing lists, and following the appropriate people on social media to keep up with the rapid trends. Web developers do not have that time to dedicate to operations work. They only need infrastructure to work for their project and it doesn't matter how well tuned the software is - if it works, that is all they need. Below are some common pitfalls I see with web developers.</p> <ol> <li>Using Apache with mod_fastcgi</li> </ol> <p>While this is the only option for php-fpm in Apache 2.2, Apache 2.4 brings along the better, high performing mod_proxy_fcgi. This method should be the standard in deploying an application in Apache. Using nginx with reverse proxy is also an alternative.</p> <ol start="2"> <li>Not befriending a SysAdmin.</li> </ol> <p>Contrary to popular belief, SysAdmins are not the preventers of productivity. Some Web Developers would benefit from being nice to a SysAdmin, speaking to them, and interacting more often. SysAdmins like to tell their "server stories" of how their application, server, or network equipment is actually performing in production.</p> <ol start="3"> <li>Using maximum power on their dev machine's VM</li> </ol> <p>Most dev VMs I see are over 2 vCPU and 4GB RAM. This brings an unreliable view of how the application will perform in production. A better way would be to create a 1 vCPU with 512 RAM and test on that. The smaller server footprint your application needs, the easier, faster, and cheaper we can scale it.</p> 2016-07-21T12:40:19+00:00 2016-07-21T12:40:19+00:00 Andrew Wippler /2016-07-21-linux-training-on-sale-until-73116/ <p>The Linux Foundation is offering select courses at a discount until 7/31/16.

In fact, I am testing out 16.04 on my Chromebook and work computer right now (Fedora 23 is on my Home Desktop). However, I can't find myself placing an Ubuntu server in production for one simple reason:</p> <p>Security</p> <p>While Ubuntu has a good security team, I can't recall in previous years a security patch introduced because an Ubuntu security individual found it. I do read about RedHat, SUSE, and Debian teams finding and submitting CVEs and patches; however it raises several questions as to why Ubuntu is not more seen in the discovery side.</p> <p><em>Is it because Ubuntu relies heavily upon upstream security?</em> That's not a bad thing. It just needs to be more transparent if it is.</p> <p><em>Is it because Ubuntu security team members label themselves as Debian security team?</em> That's not a huge problem - it just means their loyalty lies with upstream and not the current working branch.</p> <p><em>Is it because Ubuntu makes backdoors?</em> I hope not!</p> <p>The absence in this particular area just makes me wonder if Security is top priority in Canonical or if it is an afterthought. This feeling is enough to keep me from deploying Ubuntu in production. I would rather use and support distributions that make a high priority on security patches as they are on my side to keep unauthorized access of my servers to zero.</p> 2016-05-20T14:00:00+00:00 2016-05-20T14:00:00+00:00 Andrew Wippler /2016-05-20-cloud-computing-cost-analysis/ <p>Having a server in the cloud scared me at first. It wasn't the fact that being in a multi-tenant environment posed the possibility of others gaining access to my code/files - it was the cost that scared me. Not knowing if I was getting the best deal always plagued my mind. Especially since electricity, a/c, and hardware maintenance were never factored into my budgets it made it hard to justify a server in the cloud when on-premise appeared to be so cheap.</p> <p>Before I give the table of cost comparisons, I would like to point out that it is 2016. The past several years have seen a stabling of CPU power on the x86 architecture. The benchmarks have been leveling out and the CPU cycles are not really noticeable in a standard web app. I know different cloud providers have different versions of Xeon processors, but for this table, I am just going to label them as a CPU - even if they are vCPUs.</p> <p>All these prices assume that there is at least 1 TB of transfer a month and 20 GB SSD storage.

To them, your infrastructure is unknown, but to you it is known. Therefore, you can claim all servers under your control as being "in the cloud" even if they are not hosted in a public space such as Amazon Web Services or Microsoft Azure.</p> <p>Your cloud can be a raspberry pi, a single server, or multiple servers. The amount of hardware needed for a cloud service is based upon the usage of the service provided. Your reliability of the service depends on how well redundancy is set up on your part. When you get into warehouse computing (a single datacenter for one service), it might be difficult to wrap your head around how it operates to perform access to this service, but it is as easy as building a single, large computer. When building a single computer, you buy hard drives, ram, motherboard, a network card, and network equipment. Next you assemble the server, install the operating system, and finally configure the software.</p> <p>In warehouse computing, you break up the parts of your server to perform a specific task. In the storage realm, instead of attaching hard drives directly to the motherboard, they are connected via TCP/IP via either an iSCSI, SAN, or a network share (Samba or NFS). You also separate processes to different machines. Your database software (such as MySQL) will be the only program installed on a group of servers dedicated to run the database of your application. Additionally, you will have a cluster of servers running your application's server (php-fpm, django, etc.) with a load balancer in front.</p> 2016-02-12T15:00:52+00:00 2016-02-12T15:00:52+00:00 Andrew Wippler /2016-02-12-high-performant-chat-application/ <p>In a fictitious world where I started my own company and developed a LEMP-stack chat application, this is how I would do it in 2016:</p> <p>I would use WebSockets as the protocol in which data is being sent to and from the server. WebSockets has built-in support by nginx (since version 1.3). For caching, I would use the <code>expires max;</code> function of nginx for my static content (images, css, js, fonts, etc). I would also ensure static content was named in the scheme of <code>name-md5hash.ext</code>. This would allow the caching on the client side to shine.</p> <p>I would ensure my php files are gzip compressed (with .gz extension) to allow fast transferring of data between client and server. Nginx finds the .gz files when gzip compression is turned on and uses them if they exist. I would design small php-fpm servers that can support ~2,000 users at a time (basically, a dual core processor with 4gb of ram). This would allow ease of scaling at lower costs.</p> <p>I would use GlusterFS for fault-tolerant storage. I would use the <code>mount -t gluster</code> option on the servers as it would allow distributed nfs capability for storage of uploaded content.</p> <p>I would use MariaDB MaxScale as the database as it would allow for ease of scaling.</p> <p>In short, it would look similar to the following diagram:</p> <p><a href="/2016/01/chatapp.png"><img src="/2016/01/chatapp.png" alt="" /></a></p> 2016-01-29T15:00:29+00:00 2016-01-29T15:00:29+00:00 Andrew Wippler /2016-01-29-voip-troubleshooting-checklist/ <p>Voice over IP is very robust and reliable when set up properly. There are only four key areas to set up and check for issues. I have compiled the below list as things to check when an issue occurs.

We researched Cisco UM, Mitel, Lync, Shoretel, Avaya, Digium, a few hosted solutions, and a few Asterisk clones. I was one of three who sat through several presentations of <strong>the same features of every single phone system</strong>. Two weeks into this process, we narrowed the field down to Avaya and Digium with cost-to-implement for 650 extensions being the main deciding factor. The other deciding factor was these two companies did not give a speech about we should choose them because such-and-so research company rated them #1 in customer satisfaction. In the second round of finding a VoIP solution, we asked if we could do a one week test of a demo system. Both parties agreed to this test and we were sent demo units. With the test units, we selected 6 secretaries, 1 programmer, myself, and 2 receptionists to participate in making internal calls and testing each of the functions. During the week, we deployed several tests:</p> <ul> <li>Phone server interruption (I unplugged the server ethernet for 10-30 seconds)</li> <li>Call audio quality</li> <li>Phone restart time</li> <li>The time it took to set up 1 phone</li> <li>Admin user interface</li> </ul> <p>After the week was done, we asked each participant which system they liked better. Everyone liked the Digium handsets. We also received reports that call audio quality was better with Digium (I believe Avaya adds white noise). During the "Phone server interruption" the Digium phones reconnected without rebooting whereas the Avaya phones rebooted as soon as the server went offline.</p> <p>After looking at a 20 year TCO (with updates and phone upgrades), both phone systems came out to be nearly equal in cost. Ultimately we chose to go with Digium based upon internal experiences and haven't regretted it.</p> 2016-01-08T15:00:03+00:00 2016-01-08T15:00:03+00:00 Andrew Wippler /2016-01-08-ovirt-pitfalls/ <p>After you use something for a bit, you notice the issues associated with it. While oVirt has solved my pain points of high availability, there are a few which stand out.</p> <h3 id="logging-in">Logging in</h3> <p>To log in to oVirt for administration, you visit the landing page of the oVirt-engine website. This is perfect - it means I can administrate it from the web browser on my mobile phone. The issue comes when you actually need to log in - you have to click another link on the landing page to see the spot to enter your credentials. It would be nice if the landing page had the username and password fields and, after authentication, would bring up the appropriate view based on permissions (reporting, user, or admin view). Another thought is to have another drop-down box with the area to load right next to the profile to use. It could be that the design of the landing page is different than what I am used to, but there is clearly room for improvement.</p> <h3 id="without-dns-the-engine-website-doesn-t-work">Without DNS, the engine website doesn't work</h3> <p>If you have your DNS server virtualized and the storage gluster goes into a rebuild mode, your oVirt engine doesn't work. You can't log in quickly, you can't shutdown/turn on VMs, and you can't select anything (if you have managed to log in). You have to resort to the cli interface in order to do anything! Apparently oVirt queries each server via DNS before it lets you type in the login fields. This is easily fixed by managing the hosts file on each server via Puppet, but it seems like bad IT practice to do this.</p> <h3 id="the-web-interface-has-too-many-tabs">The web interface has too many tabs</h3> <p>This makes it difficult to tell co-workers how to operate the interface via email, sms, or telephone conversation. Often I find myself clicking through 5 tabs because I forgot how to get to a previous page. This could be from my inexperience with the interface, but I think it could be improved. This also makes it difficult to use on a mobile web browser.</p> 2015-12-18T15:00:08+00:00 2015-12-18T15:00:08+00:00 Andrew Wippler /2015-12-18-converting-debianubuntu-to-ovirt/ <p>oVirt 3.6 will have a better way to import virtual machines. In the mean time, here is the best method for getting an already made ova into oVirt. The example I am using is the open source log analyzer - <a class="external" href="https://www.graylog.org/">graylog</a>.</p> <p>A prerequisite is the script located at <a class="external" href="http://git.annexia.org/git/import-to-ovirt.git">http://git.annexia.org/git/import-to-ovirt.git</a></p> <pre class="z-code"><code><span class="z-text z-plain">git clone http://git.annexia.org/git/import-to-ovirt.git </span></code></pre> <p>Verify the type of the downloaded file:</p> <pre class="z-code"><code><span class="z-text z-plain">file graylog.ova </span><span class="z-text z-plain">graylog.ova: POSIX tar archive </span></code></pre> <p>This is wrapped archive, extract it.</p> <pre class="z-code"><code><span class="z-text z-plain">tar xf graylog.ova </span></code></pre> <p>Whether converting from Hyper-V or OVA, the following steps will be the same except Hyper-V's format will be <code>vpc</code> instead of <code>vmdk</code></p> <pre class="z-code"><code><span class="z-text z-plain">sudo qemu-img convert -f vmdk -O qcow2 graylog-disk1.vmdk graylog.qcow2 </span></code></pre> <p>This line will import the image into oVirt.</p> <pre class="z-code"><code><span class="z-text z-plain">sudo import-to-ovirt.pl graylog.qcow2 ovirt-nfs-storage:/exports/import_export </span></code></pre> <p>The VM can then be imported using the import tab of the storage domain where you uploaded the file.</p> 2015-12-11T15:00:14+00:00 2015-12-11T15:00:14+00:00 Andrew Wippler /2015-12-11-converting-vms-for-ovirt/ <p>My existing Hyper-V infrastructure consisted of Windows, a few CentOS, and Debian/Ubuntu guests. The best method I found to importing into oVirt was using the <a class="external" href="http://oirase.annexia.org/virt-p2v/">virt-p2v disc</a>. This required down time of the server (approx 3 hours per 100GB on gigabit backbone) and a dedicated Fedora or Debian server which had <code>virt-v2v</code> installed. I used my Acer C710 Chromebook to serve as the <code>virt-v2v</code> converter. (This is possibly the reason I had slow conversion times.)</p> <p>Once you boot into <code>virt-p2v</code>, you enter the IP address of an ssh server with <code>virt-v2v</code> installed. Unfortunately, I had to log in with root credentials as using the sudo method did not work when I tried. In some instances, my virtual machines needed the legacy Hyper-V network adapter to get an IP from DHCP and be able to ping the conversion server. It would have been helpful if <code>virt-v2v</code> mentioned this rather than giving a general username/password is invalid error.</p> <p>After successfully testing the server and logging in, the next step is to enter the target properties. These are what you will name the image, how many virtual CPUs to allocate, and the desired RAM. Next the output options have to be set. Since I was using oVirt, I selected the <em>Output to (-o)</em> as rhev. I then had to enter the <em>Output storage (-os)</em> which is required when converting for oVirt/rhev. Since these settings are relative to the <code>virt-v2v</code> server, I could have mounted the nfs import domain (defaults in getting started guide - <em>nfs-server:/exports/import_export</em> ) as /var/tmp on the <code>virt-v2v</code> converter; however, I decided to enter the nfs server and path instead as this value. Next, you select the discs to convert as well as any network interfaces and removable media. I found that you only need to select the harddrives - everything else can be configured in oVirt.</p> <p>Once you click start conversion, <code>virt-p2v</code> boots into the virtual machine and forwards data to your <code>virt-v2v</code> server. The <code>virt-v2v</code> process removes devices and adds the special ones needed to prevent a BSOD when you boot your Windows server for the first time on oVirt. Something similarly happens on CentOS based VMs.</p> <p>Once that is done you need to go into the storage tab of the cluster (in my case, Default) and select the import storage domain. This will then open up the lower third of the web interface with another tab that is labeled <em>import</em>. This will list all VM guests that have successfully been converted by <code>virt-p2v</code>.</p> 2015-12-04T15:00:46+00:00 2015-12-04T15:00:46+00:00 Andrew Wippler /2015-12-04-planning-the-deployment-of-ovirt/ <p>After I played with oVirt I needed to do several items:</p> <ol> <li>Migrate the oVirt engine to a new host</li> <li>Migrate the storage from a single NFS share to GlusterFS</li> <li>Move my VMs from Hyper-V to oVirt</li> <li>Test my setup</li> </ol> <h2 id="migrate-the-ovirt-engine-to-a-new-host">Migrate the oVirt Engine to a new host</h2> <p>This task was to prepare me for the disaster recovery scenario - what if my server room blew up - how would I recover my virtualization backbone? It might not be that important (considering I back up my VMs and can restore them anywhere), but when disaster strikes, tasks need to be simple because concentration will be difficult. As of version 3.5, oVirt had a good back up and restore operation:</p> <pre class="z-code"><code><span class="z-text z-plain"> </span><span class="z-text z-plain">#backup example </span><span class="z-text z-plain">/usr/share/ovirt-engine/bin/engine-backup.sh --mode=backup --scope=all --file=/root/engine_backup --log=/root/backup_log </span><span class="z-text z-plain"> </span><span class="z-text z-plain">#restore example </span><span class="z-text z-plain">/usr/share/ovirt-engine/bin/engine-backup.sh --mode=restore --scope=all --file=/root/engine_backup --log=restore_lg </span><span class="z-text z-plain">engine-setup </span><span class="z-text z-plain"> </span></code></pre> <p>All I had to do was run the backup script, copy the file, restore it, and run <code>engine-setup</code>. To further harden my installation, I placed the backup line in my daily <code>crontab</code> an hour earlier than my scheduled <code>duplicity</code> run.</p> <h2 id="migrate-the-storage-from-a-single-nfs-share-to-glusterfs">Migrate the storage from a single NFS share to GlusterFS</h2> <p>This next step was a bit under-sighted on my part. In my test lab, I had 4 VMs running on 1 NFS server. The NFS server I chose in the lab environment began to choke around 30 VMs and eventually crashed when I hit the 35 mark. It was not a limitation on oVirt or NFS, but on my hardware. <code>GlusterFS</code> was extremely simple to set up and their documentation is easy to follow.</p> <h2 id="move-my-vms-from-hyper-v-to-ovirt">Move my VMs from Hyper-V to oVirt</h2> <p>I will discuss this in more detail in a following post. It was mostly running <code>virt-p2v</code> on Windows and CentOS and <code>import-to-ovirt.pl</code> on Debian and Ubuntu VMs.</p> <h2 id="test-my-setup">Test my setup</h2> <p>During the transition, I had the opportune time to experience what it was like when my single point of failure (the one NFS server) crashed. It was also painful when DNS and DHCP were on servers on the failed storage server (oVirt didn't like that). Through this process, I have formulated several key steps to prevent a failure like that from happening again.</p> 2015-11-27T15:00:31+00:00 2015-11-27T15:00:31+00:00 Andrew Wippler /2015-11-27-switching-from-hyper-v-to-ovirt/ <p>For quite some time I have heard that Hyper-V was a low player when it came to virtualization. It came with Windows and was the hypervisor of choice, but it had its limitations. In my environment, we had local storage and no clustering of hosts and consequently no high availability or fail over. This brought the first pain point - we need high availability.</p> <p>On one of my hosts, the broadcom Ethernet driver kept triggering flow control and would not resume causing all of the VM Guests to go offline. This triggered the second pain point - I need high availability yesterday.</p> <blockquote> <p>What matters most in a hypervisor environment is the tools you use to manage it.</p> </blockquote> <p>I took this principle as a guide when searching for a hypervisor environment. I first looked at Hyper-V and the new licensing costs it would accrue. Next I looked at the popular VMWare ESXi, but I heard the neat features were at a premium price and all I needed was high availability. I looked at Open Source versions like KVM, Xen, and OpenStack (which appeared to be too big for my 40 VM environment). Then I found RHEV's community version - oVirt. It had all the bells and whistles I needed - Linux hosts and high availability.</p> <p>oVirt's install documents were surprisingly simple as I quickly found 3 servers to set up: an engine server, a file server, and a VM Host. Once set up, I tinkered with it, and to my delight - everything worked right out of the box (on old hardware too!) My next step was to install a few VMs and test the high availability features. It was evident that oVirt was the solution to my pain points.</p> 2015-11-13T14:59:38+00:00 2015-11-13T14:59:38+00:00 Andrew Wippler /2015-11-13-paying-for-open-source/ <p>While Open Source software is free to download, use, and depending on the license, free to distribute, it is not free to creator. The Open Source creators have to pay for hosting, branding (domain, etc.), coding (in time), and distribution. While some are offloading the costs by hosting the project on Open Source aware distribution channels such as <a class="external" href="https://github.com">GitHub</a> or <a class="external" href="https://bitbucket.org/">BitBucket</a>, many projects still lack the funds they need.</p> <p>The general rule is: if you use it, you should pay for it. How you should pay for it is entirely up to you.

In the <code>tar</code> example, the DEST came first. Did I really have to learn every command to know which order my commands were supposed to be in?</p> <p>There are a few quirks, but most commands follow the arrow law:<code>-&gt;</code> . SOURCE should come first - then DEST.</p> <p>To place the <code>tar</code> command in the arrow law way, we would write the command like the example below. Tar allows the use of multiple source locations in the form of files or folders. Each source is then compress and place in the file.</p> <pre class="z-code"><code><span class="z-text z-plain">tar -cJ /home/andrew/file1.txt /opt /folder -f files.xz </span></code></pre> <p>At a glance, one should easily recognize that the <code>-f</code> indicates the DEST/SOURCE file to be worked on by the <code>tar</code> command. Thus by typing the extraction command as the below is following the arrow law.</p> <pre class="z-code"><code><span class="z-text z-plain">tar -xvJf files.xz </span></code></pre> <p>The command that really confused me the most was the <code>ln</code>. By using the arrow law, it was easy to figure this one out. (note: in the below example <code>-s</code> is the option for making a symbolic link - not to indicate the source.)</p> <pre class="z-code"><code><span class="z-text z-plain">ln -s /opt /home/andrew/opt </span></code></pre> <p>In human readable terms, the above command means the following: take <code>/opt</code> and make it accessible by going to <code>/home/andrew/opt</code>.</p> 2015-08-02T22:05:43+00:00 2015-08-02T22:05:43+00:00 Andrew Wippler /2015-08-02-installing-teamviewer-over-ssh/ <p>The recommended way to install TeamViewer is from a desktop environment using a package manager such as Synaptic, Yum, or apt-get. Sometimes you find yourself in a circumstance when ssh is the only way you have access to your server. This tutorial will help you get it installed on Ubuntu Server 14.04.2.</p> <p>As a reminder, TeamViewer is free for personal use. If you are using TeamViewer for commercial purposes - PURCHASE A LICENSE! Purchasing a license ensures TeamViewer will be available for years to come.</p> <p>First of all, download the latest teamviewer.</p> <pre class="z-code"><code><span class="z-text z-plain">wget http://download.teamviewer.com/download/teamviewer_i386.deb </span></code></pre> <p>Next, update your apt sources.</p> <pre class="z-code"><code><span class="z-text z-plain">sudo apt-get update </span></code></pre> <p>TeamViewer needs a desktop manager and desktop environment to run. The Ubuntu Server edition does not have a GUI. The below command makes the server edition turn into the desktop edition and installs a command line page installer.</p> <pre class="z-code"><code><span class="z-text z-plain">sudo apt-get install ubuntu-desktop gdebi -y </span></code></pre> <p>Next, install teamviewer with the following command. I like using gdebi because you do not have to run <code>sudo apt-get install -f</code> to fix dependencies.</p> <pre class="z-code"><code><span class="z-text z-plain">sudo gdebi teamviewer_i386.deb </span></code></pre> <p>TeamViewer is now installed, but we have to jump through a few hoops to get it to allow us to remotely conenct. The first configuration we have to do is set up a password and then we need to enable the TeamViewer daemon. Both of these steps can be accomplished by doing the following:</p> <pre class="z-code"><code><span class="z-text z-plain">#set up teamviewer&#39;s password </span><span class="z-text z-plain">sudo teamviewer passwd password946 </span><span class="z-text z-plain"> </span><span class="z-text z-plain">#make teamviewer start at boot and start if it is not currently running </span><span class="z-text z-plain">sudo teamviewer daemon enable </span></code></pre> <p>At this point, you will be able to get your TeamViewer ID by running <code>sudo teamviewer info</code>; however, if you try to connect now, it will time out after you log in to your desktop environment. This is because TeamViewer requires the end user to accept their EULA. Since we installed TeamViewer over ssh, we were never prompted to accept the EULA. If you were to watch the monitor of the server, you would see the EULA be presented (as seen below), but not shown on the TeamViewer session. <a href="/2015/10/teamviewer-eula.png"><img src="/2015/10/teamviewer-eula.png" alt="" /></a></p> <p>To get past the license agreement, you can accept it by running the following command and answering the question with a <code>y</code>.</p> <pre class="z-code"><code><span class="z-text z-plain">sudo teamviewer license </span></code></pre> <p>You can now TeamViewer to your host, use the specified password you set above, log in to your desktop environment, and enjoy accessing your GUI over TeamViewer. Remember to play fair.</p> 2015-07-18T22:12:35+00:00 2015-07-18T22:12:35+00:00 Andrew Wippler /2015-07-18-send-aliases-over-ssh-connections/ <p>Bash reads aliases from a file only; however, this file does not have to reside on the server you are connecting to. With OpenSSH, we have to ability to send environment variables that the server allows.</p> <pre class="z-code"><code><span class="z-text z-plain">On Debian/Ubuntu systems, the default accept environment variables are: </span><span class="z-text z-plain"># Allow client to pass locale environment variables </span><span class="z-text z-plain">AcceptEnv LANG LC_* </span><span class="z-text z-plain"> </span><span class="z-text z-plain">On CentOS/Fedora systems, the default accept environment variables are: </span><span class="z-text z-plain"># Accept locale-related environment variables </span><span class="z-text z-plain">AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES </span><span class="z-text z-plain">AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT </span><span class="z-text z-plain">AcceptEnv LC_IDENTIFICATION LC_ALL LANGUAGE </span><span class="z-text z-plain">AcceptEnv XMODIFIERS </span><span class="z-text z-plain"> </span></code></pre> <p>If you remote into a mixed environment of servers - whether they be Debian, Ubuntu, or CentOS, you will need to find a common <code>AcceptEnv</code> variable. Since Debian and Ubuntu allow LC_* (everything with the prefix LC_), we are limited to forwarding our aliases over one of CentOS's variables. For me, it was easy to decide on a variable to overwrite - <code>LC_PAPER</code>. I hardly print anything and I especially do not print on remote servers.</p> <p>In order to send your aliases into a remote server, you have to set up your environment first.</p> <p>In <code>~/.ssh/config</code>, you need a line that sends the environment variable of your choice.

The second line is where we actually connect to the server. The third line is the command executed on the remote server: cleanly print the contents of our environment variable, put that information in file descriptor 3, and reload bash with that file as the only configuration file.</p> <p>To make the process easier, I have place the following function in my .bashrc. Since the function has $@ variable, I can use it as a replacement to ssh and I can pass any needed ssh switches to my new function.</p> <pre class="z-code"><code><span class="z-text z-plain">function ssha() { </span><span class="z-text z-plain">LC_BASHRC=$(cat ~/.bash_aliases_xfer; exec 3&lt;&amp;-) ssh -t &quot;$@&quot; &#39;exec bash --rcfile /dev/fd/3 3&lt; &lt;(printf %s &quot;$LC_BASHRC&quot;)&#39;; </span><span class="z-text z-plain">} </span><span class="z-text z-plain"> </span></code></pre> <p>After I reload my bashrc ( <code>source ~/.bashrc</code> ), I can then pass my aliases into my new ssh session: <code>ssha user@remote -i ~/.ssh/remote_id -X</code>.</p> 2015-06-11T22:25:42+00:00 2015-06-11T22:25:42+00:00 Andrew Wippler /2015-06-11-named-virtual-hosts-on-aws-ec2/ <p>Named virtual hosts are not enabled by default on an Amazon AMI. To enable them, edit /etc/httpd/conf/httpd.conf and uncomment line 991:</p> <pre class="z-code"><code><span class="z-text z-plain">NameVirtualHost *:80 </span></code></pre> <p>You can then begin adding your named virtual hosts in the /etc/httpd/conf.d/ directory.
