How do you DHCP Release & Renew in Jaguar? I know in Windows 2K & XP you can open up the command prompt and type "ipconfig /release" followed by "ipconfig /renew" and get assigned a new IP address from the DHCP server on your local network .. but how do you do this in Jaguar? I thought you could accomplish the task by calling "ifconfig -d <ethernet interface>" followed by "ifconfig -u <ethernet interface>" but this doesn't work. anyone know how to do this ...
