It wanted to write to /etc/resolv.conf which was on a read-only file system at the time. Eventually, it crashed out - perhaps trashing the interface configuration on its way down. I moved resolv.conf to /usr/local/etc and symlinked it in /etc - and the problem appears to be resolved. I haven't seen any other strange network related problems since. Thanks, Seth Henry BTW - the Linksys USB100TX uses the aue driver. Thanks, Seth Henry On Fri, 4 Apr 2003, Toomas Aas wrote: > Hi! > > > All of these machines have identical hardware.
