well, if the connection on the server's side is going-down you should see lines that look kinda like this in it's
/var/log/messages log file:
Code:
Dec 20 19:46:22 darkstar kernel: eth0: link down
Dec 20 19:46:24 darkstar kernel: eth0: link up, 100Mbps, full-duplex, lpa 0x41E1
Dec 20 19:46:58 darkstar kernel: eth0: link down
Dec 20 19:46:59 darkstar kernel: eth0: link up, 100Mbps, full-duplex, lpa 0x41E1
also, maybe post these parameters just to make sure they are sane:
Code:
cat /proc/sys/net/ipv4/tcp_fin_timeout
Code:
cat /proc/sys/net/ipv4/tcp_keepalive_time
Code:
cat /proc/sys/net/ipv4/ip_default_ttl
there's others you could look at but i can't remember them right now, so this is just my $0.02...
