Ok, I'm running Debian Unstable, though deployed using Knoppix. I am also using Driverloader for use with my wireless card, however... I don't think that stuff matters.

Right now, in order for my wireless network to work, I have to do the following:
1. Boot
2. Open Terminal.
3. Run SU
4. Run: iwconfig eth0 essid mynet mode ad-hoc
5. Then I go to the KNOPPIX menu on my taskbar and run Network Card Configuration, which updates the DHCP
6. Then, network works.

How can I modify the startup files to include:
1. The SSID
2. Mode - Ad-hoc
3. Update DHCP

Thanks!

If you need additional commands run at boot time then you can add them to the end of your rc.local file.
