divine
divine will use ARP requests to look for hosts that are always up in the networks that you frequently use your laptop in and then set the IP configuration including /etc/resolv.conf and write proxy settings in /etc/proxy. A perl script to edit your netscape 4 preferences is included. You can also run a custom script for each network to edit /etc/printcap or /etc/issue or whatever you feel like. The ARP method is much quicker than the "ping" method that other solutions use.

Recent releases
- 30 Jan 2001 06:12
Release Notes: Better edit-netscape-proxy. divine will now cancel the ARP probe thread. This is mostly a cosmetic problem, but on some buggy PCMCIA drivers/cards it also fixes a race condition.
- 30 Jan 2001 06:12
Release Notes: A switch to libnet-1.0 (won't work with prior versions), and 6 retries instead of 3.
- 30 Jan 2001 06:12
Release Notes: A change of the source IP of the ARP probes to 0.0.0.0 (avoids network overlaps), and strenghened IP takeover detection.
- 30 Jan 2001 06:12
Release Notes: An updated man page, and a minor kludge that avoids grabbing an already in-use IP.
- 30 Jan 2001 06:12
Release Notes: Divine now exits with exit code 2 if it did not receive any answers.

Re: divine
It looks like you need to install libpcap and libnet. The homepage describes this requirement. If you are using a RPM based distrobution, you probably need to install the -devel RPMs too.
