Google isn't very helpful, nor Sean> is the man page. It basically deconfigures any ip address associated with the interface. I use it frequently when switching back and forth between wireless and wired interfaces to the same network (e.g. while debugging a wireless problem). If both interfaces are configured on the same network (which might happen by associating and getting DHCP from wireless, then plugging an ethernet into a LAN port and getting DHCP for that), the networking stack gets confused over which interface to use to reach a local destination, so deconfiguring helps unconfuse things. Just downing the interface doesn't necessarily help, btw. This series of commands (not tested) should show what is happening: dhclient eth0 ifconfig eth0 ifconfig eth0 down ifconfig eth0 ifconfig eth0 0.0.0.0 (or just 0 for short) ifconfig eth0 -- Russell Senior, President [email protected] _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
