ISI's DHCP client (dhclient) is good for when you connect to a network. Then a small shell script to ifconfig down the interface will do the "off" part of the job. If you insist on static routes (and/or static configuration), you can stick with hardcoding such things in said shell script. -- Will Andrews <andrews@technologist.com> GCS/E/S @d- s+:+>+:- a--->+++ C++ UB++++ P+ L- E--- W+++ !N !o ?K w--- ?O M+ V-- PS+ PE++ Y+ PGP+>+++ t++ 5 X++ R+ tv+ b++>++++ DI+++ D+ G++>+++ e->++++ h! r-->+++ y?
