--- Begin Message ---Package: ifupdown Version: 0.6.4-1 If you remove the default route entry from the routing table, or change it, then `ifdown -a' seems unable to deconfigure the network interface properly, leaving the machine in an unstable state. This worked until I updated the ifupdown package, however now, as you can see, ifdown produces an error message and actually leaves the eth0 interface configured: # /sbin/route del default # ifdown -a SIOCDELRT: No such process # ifconfig -a | grep eth0 eth0 Link encap:Ethernet HWaddr 00:B0:D0:4D:6E:69 Scott -- Scott James Remnant I'm a bloodsucking fiend!
