Hi.
I've a problem with my server/router, that I've seen on various kernels. currently I'm running 2.4.21, but I've seen the problem on 2.4.20 and 2.5.70, too. I'm using a 3com 3c509 ISA ethernet card.
When this server stays a longer time (about one night, 12 hours) without network-traffic, it seems like the whole network-interface falls into a very deep sleep. It's very hard to wake the machine up. Today it was _very_ hard. First I tried to reach the internet through this machine (it's a router), but it didn't work. Every packet was thrown away by the router. Then I tried to login via ssh into the machine, but I got no response. Then I tried to ping the machine. All packages got lost. But after a few minutes of pinging, suddenly the machine responded in normal speed. From now on ssh and routing was possible too. It's like I have to tickle the machine a bit, before its network-interface wakes up and I'm able to transmit some packages.
I've no idea for the reason. Thank you for every help.
