telnet Troubleshooting Using Windows

Sometimes you have to troubleshoot Linux servers from a Windows PC. The telnet commands are the same, but the results are different. Go to the command line and type the same telnet command as you would in Linux.

Screen Goes BlankSuccessful Connection

If there is connectivity, your command prompt screen will go blank. Using the Ctrl-C key sequence enables you to exit the telnet attempt.

Connect Failed Messages

The Connect failed messages are the equivalent of the Linux Connection refused messages explained earlier and are caused by the same reasons:

     C:\>telnet 172.16.1.102 256
     Connecting To 172.16.1.102...Could not open connection to the host, on
     port 256:

     Connect failed
     C:\>

telnet Timeout or Hanging

As explained previously, if there is no connectivity, the session will appear to hang or time out. This is usually caused by the target server being turned off or by a firewall blocking the connection.

     C:\>telnet 216.10.100.12 22
     Connecting To 216.10.100.12...
