Hi,
Check if telnet is enabled in the xinetd.d configuration.

1. Change disable=yes to disable=no in the /etc/xinetd.d/telnet file.

Hi,
Does the telnet port listens ?

#lsof -i | grep telnet

Does xinetd daemon running ?
#ps -ef | grep xinetd | grep -v grep

Check the services enable at startup
#ntsysv

Hi boss,
xinetd should run.

Using ntsysv enable xinetd service and reboot the server. It should solve the problem.

Hi,

1. Is xinetd installed first.
rpm -qa | grep xinetd.
2. If not install it first. If installed, is it enabled.
chkconfig --list xinetd
chkconfig --levels 345 xinetd on
3. Start the xinetd service.
service xinetd start.
4. Is telnet server installed.
rpm -qa | grep telnet-server.
5. If not install it.
6. Enable telnet service. See my earlier post. Set disable=no.
7. Try telnetting to the server from the server itself.
telnet 0
telnet or
8. If this works and still you are unable to telnet from the network, problem is with the firewall.

Ok, I messed up on that last message. I meant to say I telnet in on port 22. I don't know where I got 8443 from. Oh yes, web interface is port 8443 running Linux Mandrake SNF 7.2

You might want to try a program called putty for win32 systems. You can probably find it doing a google search. I know I run linux mandrake single network firewall and have to use putty to access it via ssh connection. It will not accept any other type. I telnet in on port 8443 using putty
