Hi all,

It's probably something really obvious, but I can't figure out how to get my eth0 to renew it's IP address from a DHCP server after boot. If I forget to plug in my ethernet cable on boot (it's a laptop) then the eth0 interface doesn't obtain an ip address, and hence the interface is not brought up. I typed:

# ifconfig eth0 up

which brings up the interface, but doesn't poll the DHCP server for an address. In the windows world I'd type ipconfig/renew but I can't find the equivalent in linux.

Thanks in advance

I could be wrong but i think it is

# dhcpcd eth0

usually your net configs can be found in /etc/conf.d/net

or oldschool:
good luck

Hi, thanks for the replys

I'm using Fedora core 2, so I think all my net configs are in /etc/sysconfig/network-scripts (though i could be wrong as I'm a newb)

In the ifcfg-eth0 file I have...
BOOTPROTO=dhcp

...which as far as I know enables DHCP on this interface, but it only seeks an ip address at boot. Can I run this as a script and reset the interface? (I thought by bringing the interface up it would do this, but apparently not)

OK, I got the answer from the Fedora irc channel...

ifup eth0

Apparently "ifup is a script that reads your network card configuration from a file and does the ifconfig and dhcp client stuff for you". I was trying to use ifconfig unsuccesfully.

Thanks for the help guys
