telnet seems to have a -d option for debug, did you try that ? Otherwise, general hints are : "tail -f /var/log/messages" on one terminal while you execute telnet on another to see if any helpful messages arrive there. Sometimes doing an "strace <your command> 2>log.file" will show the problem. The tricky part is in interpreting the file. The best bet is to start at the end of the file, where you should see the error message being printed out. Of course, you need the strace package, and it's entirely possible that the answer won't be here. Dare I say it ... try connecting with a telnet prog on another operating system in case there is a setup prob on Linux causing the effect. It possible that your ISP blocks all telnet traffic. Why not phone and ask them ? If that's the cause, you need an ISP upgrade ... -- Regards, Paul
