  • Call to undefined function http_post_data()

    After updating my server from testing to Squeeze it suddenly crashed after running a high CPU % perl script. Being unresponsive I reset the machine to reboot it. After booting up and testing websites running on it I came along an odd PHP error; Call to undefined function http_post_data() Probably due to PHP updates from…

  • Squid MRTG stats

    I talked about MRTG stats for Squid in the past but apparently forgot to include the .mib file. So, here it is. Download this file and put it in /usr/share/squid/mib.txt. I don’t quite remember where I found that mib file. Probably included with Squid on Gentoo or the world wide web… But I couldn’t find…

  • Debian MySQL Gem file error

    When installing the MySQL Gem, I had this error: Building native extensions.

  • MRTG and network interfaces

    I tend to restart OpenVPN a lot due to config changes. As a result, this brings quite some issues to MRTG (or more precisely, SNMP), due to the fact tun devices change of ID. A while back, I found a quick fix for this; rename the interface targets from their respective ID to their name:…

  • Theme, blog, and stuff

    As you noticed… Or perhaps didn’t notice, I’ve started using a new, simplistic theme a couple of days ago. Kinda thought it might be too simplistic (I’ve hidden the sidebar, there’s no search or archive, etc), but I started to, you know, get attached to it. So it’s here to stay, for a year or…

  • Zero

    Big grats to good old Zero and its one year uptime! 😉
