I'm pretty new to Linux; this project is me trying to learn more. I've done login scripts before but not boot scripts, so that's one of my questions. My other question is how to get an ad-hoc network working with just terminal commands, so that I can make a boot script to do it. I'm running Fedora 18 off of a flash drive for now, but when I'm done configuring I'll be copying everything to an old laptop's hard drive. (The goal of this project is to not have to buy a better wireless router)
The most luck I've had setting up an ad-hoc was by using Gnome's "Use as Hotspot..." button in my wireless network settings, and then changing the name and WEP code (Can I use other encryption methods?) using iwconfig in the terminal, but I want it all done with terminal commands so that I can just run a script to set it all up. I think I can figure out how to use iptables to set up my port forwarding and junk myself, but first I need to get this computer able to share its internet connection wirelessly.
