Re: [linux-dell-laptops] how can i configure my eth0 interface to get dynamic ip from proxy server
- It depends a bit on your distribution. In mine, gentoo, you can get an
IP address (assuming you are using dhcp) by doing:
localhost root # dhcpcd -d eth0
For eth0, replace with eth1 or whatever port it is you are bringing up.
Some distributions use either "pump" or "dhclient" instead of dhcpcd
(use "man pump" or "man dhclient" to find usage info for those, I
haven't used either in some time). The command "ifconfig" will tell you
which interfaces have been configured. For example here is the output of
mine (after using dhcpcd to bring up the eth0 interface):
localhost root # ifconfig
eth0 Link encap:Ethernet HWaddr 00:0B:DB:18:1B:C0
inet addr:18.104.22.168 Bcast:22.214.171.124
UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1
RX packets:248369 errors:0 dropped:0 overruns:0 frame:0
TX packets:142877 errors:0 dropped:0 overruns:0 carrier:5

TX packets:1503 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:820976 (801.7 Kb) TX bytes:820976 (801.7 Kb)
As you can see I have two if's configured, eth0 and lo. The important
thing to look for is does the interface have an associated IP address in
that paragraph. If it does not then something went wrong. You can
check the logs in /var/log/ to see what went wrong. In my distribution
dhcpcd writes to a file in /var/log/dhcpcd/current with info about its
success or failure in getting an IP address and other info (routing,
Note, doing it this way (dhcpcd or whatever on the IF) is kind of going
through it the hard way. Most distributions have a preferred method
using some init script but sometimes when you are first setting things
up its useful to know the manual "hard" way.

What distro are you using? Most of the bigger ones have some GUI tool
to do things like this. Mandrake has its Control Center, Libranet has
its adminmenu, most KDE- and Gnome-using distros have something on the
panel menu for doing settings like this.
If you're feeling adventurous you can log on as root and edit
/etc/sysconfig/network-scripts/ifcfg-eth0; it's pretty obvious how you
would do it and there's online help too.
