This is a list of my favourite open source tools that I often use. I’ll up date this on occasion as I add discover and explore new things.
Documentation and ticketing
DokuWiki
This is a great little product and it’s very quick and easy to implement.
From the web site (all true!)… “DokuWiki is a simple to use and highly versatile Open Source wiki software that doesn’t require a database. It is loved by users for its clean and readable syntax. The ease of maintenance, backup and integration makes it an administrator’s favourite.”

Ostiket
Great product if you need to quickly set up a job tracking system. Runs under LAMP and is robust and easy to use. Also comes with support and hosting options if you need them.

Mediawiki
Useful for bigger and more free style projects and also runs the wikipedia site. The grand daddy of Wiki’s!

Wireshark is one of the great open source projects that is an insanely great tool. Know exactly what is running on your network and dig down to forensic levels.

pfsense
I’ve written about pfsense before it’s a fantastic firewall routing system that can also be used to set up VPN’s and lots, lots more. Another project that you can purchase pro help for if you need it, or if management want to know that the thing is supported. It can run on just about anything and you an also get dedicated hardware if you want it. But you can put together a router from old parts and it will run just fine.
