For reasons unknown one of my favourite and most essential tools arping is not available in OPNsense's package repository. On OPNsense, the preferred method of incorporating mainline FreeBSD packages (according to the official documentation) is to use opnsense-code to install the ports system which,…

Mesa 10.0.4 requires LLVM < 3.x to compile correctly or it will complain about missing header files. Add LLVM to package.mask: # echo ">sys-devel/llvm-2.9-r2" >> /etc/portage/package.mask

Just like it sounds, the package you are trying to emerge is attempting to write files outside of your prefix. Depending on the situation it may be that there is no fix, but it is possible that upgrading eselect or portage and re-syncing the portage…

Apache Cordova is an open source framework for rapidly generating mobile apps from HTML5, CSS and JavaScript. At present, Cordova supports 7 mobile platforms with plans to expand.

You have two options for monitoring things like load average and logged in users on a remote host with Nagios or Icinga: SNMP (which you are probably already using for Cacti or a similar graphing/monitoring solution) or the Nagios Remote Plugin Executor (NRPE). NRPE gives one greater flexibility in the…

Gentoo started using the APACHE2_MODULES USE-flag-extending variable to manage Apache's modules in portage some time ago. The list of modules I migrated with (likely provided by the Gentoo documentation as a recommendation) seems to be missing those responsible for http…

This condition occurs when the compiler requires more memory than is currently available.

Out of memory:…

This is a very old bug but I'm covering it here anyway because it keeps popping up on dusty servers and I forget how to solve it. If you do a world update on a box that hasn't had one in about a year you might notice that dev-perl/DBD-mysql (in the case in front of me, 4.01.3) fails to compile and nothing…

After updating my installation of ffmpeg and ffmpeg-php on one of my web servers I noticed that images grabbed using ffmpeg-php's getFrame function spat out weird garbage, usually three corrupt looking frames across the top and static in the bottom two thirds. I tried tinkering with it for a very long…

Gentoo recently made the switch from lzma-utils to xz-utils, to quote the project page at http://tukaani.org/lzma/: LZMA Utils are legacy data compression software with high compression ratio. LZMA Utils are no longer developed, although critical bugs may be fixed as long as fixing them doesn't require…

Suhosin is a Korean word which, roughly translated, means guardian angel. It is also the name of a clever PHP extension brought to us by the Hardened-PHP Project. When I found out it could provide transparent on-the-fly session and cookie encryption I thought sexual thoughts and sped off to install it.…

What a mouthful. The more I worked with mod_vdbh the more I realized it's not for me. Neither is its more advanced fork, mod_vhs which adds some useful extensions. While database-backed configuration is an elegant solution to mass virtual hosting it falls short in that it lacks these key (for my purposes)…

I was stoked to find out Xen 4 had finally made it into portage a couple weeks ago, The improvements are so sweet I had been checking gentoo-portage.com every few days or so. Let's take a look at a few of the advances Xen has made since…

TFTP is most commonly used these days to remote boot small images, move firmware and configuration details. Despite its name it shares little in common with FTP other than it's primary purpose: moving files. This post will leave you with a configured and running TFTP daemon on Gentoo. There are a number…
