I'm running the unstable dist and a recent upgrade seems to have destroyed information needed for my network interfaces. Running ifconfig displays the proper details for eth0 and lo but running ifup gives a "Bad file descriptor" error. The /etc/network/interfaces file is intact but under /proc/sys/net/ipv4/conf/ there is only all and default and no eth0 or lo anymore.
How do I regenerate these? What is the source of this problem? Can I keep it from happening again? adTHANKSvance, Chris
