"ifconfig" will get you most of that. You will also want - "route -n" - Check routing i.e. default gateway n' stuff. "cat /etc/resolv.conf" - check your nameservers. I think this is standard in all distro's. The release/renew thing I'm not sure about. It may have something to do w/ pump (a dhpc program) or something like that. I would also like to know how to do this. If it's what I'm thinking of it releases a DHCP address and requests a new one. Although if your dhcp server is setup to keep a lease for so long and you try to change it will it give you a new address or the one already leased to your MAC address? Anyone know? To restart your network you can do a (RH based/SysV? Don't know about Debian) "/etc/rc.d/init.d/network restart" should work depending on the distro. What info are you trying to get? sim > What's the Linux equivalent to the Windows ipconfig command? Also, > how do I do release/renews? > > David
