VPS.net review

I've been running a single node from VPS.net for about a year now.  Please note that my specific experience has been in their "Chicago Zone D data center", but if you check out their status page or search Twitter, you'll find a lot of others having the same issues.  While there's a lot of good things to write about, where they fail is the most important area to me: availabilty.

Lead SysAdmin position available

There's a blog post to follow with when/why, etc., but without further ado:

I'm moving to a new position at Buckle, and that means we need a new Lead SysAdmin.  It's a great job at a great company, in a great place to raise a family (Kearney, NE).  You get paid well, get a good yearly budget for new toys equipment, and it's overall a very fun position.

Sysadmin Humor

I laughed out loud when I saw this XKCD comic this morning:

Apache mod_proxy '[error] (13)Permission denied' error on RHEL

Had an interesting issue today working on a mod_proxy setup of Apache forwarding requests in a reverse proxy setup to a backend Tomcat server. No matter what I did, I kept getting this in Apache's error log:

[error] (13)Permission denied: proxy: AJP: attempt to connect to 10.x.x.x:7009 (virtualhost.virtualdomain.com) failed

Teaching Java How to Commit Suicide

At $work, we have a lot of java processes that are ran via cron and other wrappers that do some pretty critical tasks. The apps have been written so that the whole thing is wrapped in a try/catch that will call system.exit(1) should something not go right. Our wrapper scripts watch for a non-zero exit code, and alert Nagios if something went wrong.

ZFS in the Trenches presentation at LISA 09

Just got the chance to finally sit down and watch Ben Rockwood's presentation at LISA 09: ZFS in the Trenches. If you are even thinking about ZFS and how it works, it's a very informative presentation. There is very little marketing-speak, and he very specifically targets sysadmins as his audience. Great stuff!

QuickTip: Fix Eclipse Galileo buttons on Ubuntu 9.10

There's a nasty upstream bug in GTK present in Ubuntu 9.10 that makes Eclipse Galileo all but unusable -- specifically it makes clicking many buttons with the mouse just stop working. You can use tab and spacebar to make it work, but that's not much of a workaround. All you need to do is set an environment variable before starting Eclipse:

export GDK_NATIVE_WINDOWS=true

Share Your Eclipse Plugins and Configurations Across Platforms

Over the years, I've come to know and love Eclipse.  Though it has roots in Java, ironically, I use Eclipse for just about everything except for coding Java (if I wrote Java code, I'm sure I'd use Eclipse).  Eclipse is great for browsing Subversion, coding PHP, coding Perl, and even coding shell scripts.  For die hards like me, there's the viPlugin that allows you to use all the vi commands you know and love within Eclipse.  About the time you get your perfect Eclipse setup established, you buy a new laptop on a new platform.  Or, in my case, I have three "primary" development workstations, each on a different OS.  The rest of this article will show you how to hook Dropbox into your Eclipse installation, allowing you to share your plugins and configurations across different versions of Eclipse, on different machines, and even on different platforms.

NGINX Performs Well on Solaris 10 x86

Just a quick posting of some simple benchmarks today.  Please note, these are not the be all, end all performance results that allow everyone to scream from atop yonder hill that Solaris performs better than Linux!  This was just me doing a little due dilligence.  I like Solaris 10, and wanted to run it on our webservers.  We're looking at using NGINX to serve up some static files, and I wanted to make sure it performed like it should on Solaris 10 before deploying it - you know, right tool f

Ask SAJ: What to do with Apache logs > 50GB?

Our site at $work is generating Apache logs that, when combined sequentially into one file, are larger than 50GB in size for one day's worth of traffic. AWStats' perl script pretty much chokes when working on this much data. Last I checked, Webalizer wasn't much different, and probably wouldn't scale up to that amount of data either. Does anyone out there have any advice on a commercial solution for Apache log analysis that can scale up like that?
