There are four basic network states I would have my notebook in, 1) Ethernet on 192.168.x.0 LAN in my apartment 2) Ethernet on 192.168.y.0 LAN in my office 3) Dial-in, PPP, to the registered net in the office 4) Stand-alone Some states would preferably have NFS mounted volumes; some would even want to run services like NIS or Samba. All networked states need to have DNS handled from both the standpoint of different servers and what the machine gives itself for the domain portion of the hostname. Right now, I need to get in there and do some serious tweaking as root to get one setup to work after being in another. Ideally, I'd want to make the computer figure out which net it is on during boot, but I think this might not be the level to start at. My first goal is to script or otherwise automate the changes root does to go from one state to the other. I am sure others out there have wanted to use their notebooks in ways like this.
