I keep forgetting to mention a firewall for Ubuntu. This is because I am behind a router and consequently a firewall is not essential. However, Ubuntu has a very good firewall called UFW that is installed but is disabled by default. The best way to configure it is to install a program called “Firestarter” from Add/Remove Programs.
I have also downloaded and installed the pre-release version of Ubuntu 9.10 “Karmic Koala”. The excellent news is that 9.10 has solved all of those annoying problems that I have had with my D-Link and Netgear Wi-Fi adaptors. The Netgear WG111works “out of the box” and the D-Link DWL G132 works after installing the windows drivers (both of the .inf files) via Ndiswrapper.
The only problem I am having with 9.10 is that I can’t connect to the printers on my Vista and Windows 7 machines. However, updates are coming through every day and I hope that this can be resolved. Both of my printers work well when connected directly.
