Check to see if you are running the DEC Tulip drivers, if thats the case there are known problems with them and upgrading to the 2.4 kernel seems to help. Also if thats your problem, you don't have to reboot your machine, just bringing the network up and down will reset them and get them working again. (on redhat/mandrake and some others "/etc/rc.d/init.d/network restart") On a firewall at work I put a bash scirpt that would ping sevral addresses and if they were ALL down it would reset the network, you could try making a similar program, sorry I can't supply it for you, I stopped needing it since I upgraded it, and it have since gotten lost in the wood work (I can't remember what I called it :).
