ipconfig /renew Linux equivalent ?

[Admin32]

Hi everyone,

I've been searching for a way to force a linux workstation to obtain an IP address without booting, similair to the 'ipconfig /renew' command under windows.

Anyone that can help ?

Cheers,

Hi,

take a look at the "pump" command. It manages the ip configuration via dhcp on a linux machine.

run netconfig, select DHCP and try, it should get IP address Automatically, else just /etc/rc.d/init.d/network restart, this will get IP address from DHCP without rebooting the machine.

Hi,

Just give this command as root.

#dhcpcd -n

It will renew the IP address,

Hi,
You can get dhcpcd here:

Try 'pump -i -R'.

'pump' is the 'dhcpcd' replacement on RH7+8 systems.

In Debian: use "dhclient eth0"
Often (in many distros) if you have configured to use DHCP in netconfig (or YaSt or debconfig or whatever), all you need is ifdown eth0; ifup eth0.
You need the ifdown in case you ended up half-up during bootup. Then ifup should call pump or dhcpd or dhclient automatically IF you configured for eth0 for DHCP.

hey, I'm using Redhat 7.3-9.0. As root typing service network restart seems to work.

simply try (as root) :

ifconfig
