SCO telnet issues

[KenCunningham]

Hi Guys and Girls and compliments of the season to all - have a great New year.

My problem: telnet seems to have stopped accepting connections to one of my boxes. When I try to connect, all I get is:

"telnet: Unable to connect to remote host: Connection refused"

This box has worked perfectly for three years and it is still pingable, and my own thoughts are that there have been changes to the routing, but the network admin denies this. Are there any things I can check out to confirm or refute this (a ping from the box just hangs saying that the host is down). I'll be back in next Monday, so any responses by then would be much appreciated. Again, all the best.

Ken,

Could be that there is a problem with in.telnetd or the telnet daemon has been shut off. Can you rsh, rlogin or ssh into the box instead? How about ftp? If there has been some sort of routing change, then ftp would most likely by screwed up as well, if not then telnet would most likely be the root cause.

If you can access the box, check to see if the telnet daemon is running, perhaps it needs to be shutdown and restarted if it is running. For routing, netstat -rn, ifconfig -a, and your host file need to be verified.

Let me know what you find.

Normally telnetd is launched by inetd.
check /etc/services.
Another option is your root filesystem is 100% full

Many thanks for the responses - it turns out that the NIC itself was faulty, so it's been swapped out and is now working as it should. Thanks again.
