Random Disconnects


I just started renting a dedicated server. It has Debian 3.1 loaded on it and is on a 100Mbit connection. At random times during the day (at least once an hour) I get disconnected. SSH, FTP, and my game server all get disconnected. I have contacted my servers tech support and they say everything is perfectly fine.

I am new to linux but figure this must be a networking error. Putty returns an error that only comes up when it can no longer reach the server. I would like to figure out exactly what is happening. Is there some kind of program I can run that will be able to test the connection constantly and document when and maybe even why the brief interuptions in service are occuring? The more evidence I have to show tech support the better. Any help would be greatly appreciated.

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...
