Why are tcp services falling over regularly?
I've had a quick look around for solutions to this, but no luck.
Running RH7, kernel 2.2.16-22. For various reasons we are running telnet on this box, every so often it refuses connections. No obvious reason eg I can telnet to it, do some stuff, then logout. 30 mins later, I get connection refused on *all* ports, eg 25, 110, 23 etc. This is all on local network, not connected to net, no ipchains running.
Any ideas ??
All the xinetd stuff /etc/hosts.allow is working OK. I've even tried checking that the eth0 module is not being unloaded.
PS I know ssh is better, but that does not solve my problem, especially on pop3 and smtp ports.
