When I try to connect through telnet from a Windows system to Unix, I am not able to connect. I am getting this log error. Is this related to a firewall issue, or anything I need to mention in the etc\service file?

"Telnet is busy with its port23"

Does that mean that telnet is not properly working, or do I need to mention a different name here?

There's nothing to take care about. OSs do not matter. TCP/IP is transparent about that. –  m0skit0 Oct 27 '11 at 16:47

This looks like a network issue, not a telnet one. Either your Windows firewall (or any other you are using) is blocking telnet, or your router is configured to block it.

you mean NIC card, because ping is working but no telnet,, do we need to check etc\host or service file in such a way that ip address conflicting –  steveaston Oct 27 '11 at 16:36
    
NIC card? :S Anyway, try with netcat to open a TCP connection to port 23. –  m0skit0 Oct 27 '11 at 16:45
