what is "ipconfig /renew" in linux ?
 

How do I do a "ipconfig /renew" in Linux ?

ifconfig is the linux equivalent but I forget if you can release or renew ip addresses using it. You could always restart your network in /etc/init.d. Usually called net.eth0 or network...something along those lines.

Take a look at dhclient:
dhclient eth0

dhclient eth0 did the trick :)

Thank you for the replyes.
