We love python virtual environments, but under FreeBSD we occasionally see issues where pip is not correctly using the /usr/local/include and /usr/local/lib paths to compile installable modules. The Problem This can produce errors such as the below, which we saw when doing a ‘pip install pycrypto’ operation: src/_fastmath.c:36:11: fatal error: ‘gmp.h’ file not found Even… Read more »
NginX “service nginx upgrade” / kill SIGUSR2 results in shutdown() failed (54: Connection reset by peer)
Friday, July 22, 2016
Huge thanks to Ganbold Tsagaankhuu who finally got to the bottom of this issue. NginX is a great web server, and is built from the ground up for high volume, zero down time environments.

ZTE Falcon Z-917 via USB with pfSense and FreeBSD
Friday, May 6, 2016
One of the things on our list has been to setup a proper dedicated cellular backup system setup here at the office. This was harder than it seemed due to the fact that T-Mobile here uses the 700 Mhz band for LTE. This is really an odd frequency and 700 Mhz is not supported by… Read more »
FreeBSD Hangs on “Trying to mount root from zfs:zroot”
Friday, April 8, 2016
There are many reasons this can happen, but this one I believe is unique in terms of searching the internet for the error. We’d see a newly imaged (or restored from backup) ZFS-based server boot fine then hang here: Trying to mount root from zfs:zroot After banging my head into it for some time thinking… Read more »

Poudriere “Error: Invalid port origin ‘/usr/local/sbin/pkg’ not found”
Sunday, January 10, 2016
This was quite the random error I ran across this week and could not find anything similar or a solution. After years of faithfully building our FreeBSD pkg repository poudriere started reporting these weird errors and refused to build anything: ====>> Error: Invalid port origin ‘/usr/local/sbin/apxs’ not found. ====>> Error: Invalid port origin ‘/usr/local/sbin/pkg’ not… Read more »

Wednesday, December 23, 2015
Logentries is a SaaS service which lets you stream logs (and lots of other things) from multiple locations and servers for review and processing on their platform. They provide out-of-the-box installers and packages for a number of Linux and UNIX operating systems but don’t directly support FreeBSD (yet). However their agent consists of a few… Read more »
