I think there is another dhcp implementation called dhcp-client, but
dhclient is what shows up on my ubuntu box.
Another way to tweak networking is with the boot-up scripts in /etc/init.d
# stopping your network:
$ sudo /etc/init.d/networking stop
# start up the network:
$ sudo /etc/init.d/networking start
# both in one command:
$ sudo /etc/init.d/networking restart
The /etc/init.d/networking script will use values from /etc/network/interfaces
Example interfaces file:
# Local loop-back interface:
auto lo
iface lo inet loopback
# my wifi interface (from memory... I'm not near my laptop)
auto eth1
iface eth1 inet dhcp
wireless-essid myWirelessAPid
# wireless-essid someOtherWirelessEssid
When I change APs I "just" edit the interfaces file to uncomment the
essid I want to use, commenting out all the others (I have 6-8 listed
in there) and then run the restart script. It's annoying, but it's
good to know about for debugging.
