Start Trac on Startup – Init.d Script for tracd
As part of a server move, I went on to reinstall Trac. I’ve tried to install it as FastCGI but I failed to configure the clean URLs properly. I got the clean URLs to work if the user access them, but Trac insisted on addeing trac.fcgi to the beginning of every link it generated. So I’ve decided to use the Trac standalone server, tracd.
The next problem I faced was how to start the Trac automatically upon startup. The solution was to use an init.d script for stating Trac. After some searching, I didn’t find an init.d script for tracd that were satisfactory (mostly poorly written). So I went on an wrote my own init.d script for tracd.

Samba and Firewall Configuration
I’ve been using Guarddog as a GUI for iptables for some time. I’ve configured it to allow to connect to samba network shares but for some reason it won’t allowed me connect to the shares without the disabling the firewall first. The blockage happened despite the proper configuration in Guarddog. So today I decided to look again at the problem and fix it.
After inspecting the output of ‘dmesg’ I found out that it tries to connect to 192.168.2.255 (192.168.2.* is my network), which is the broadcast address for the network. I tried enabling connection to the address and to my surprise this fixed the problem. I guess samba for some reason requires access for the broadcast for some name/address lookup of hosts in the network.
