Networking problem ?

Hi,

How to check whether a port is working properly or not ?

I am getting a Error message Could not open connection to the host, on port 23: Connect failed.

Thanks !!

This error message is probably the result of the telnet daemon (which listens on port 23) not running on the target machine.

Try using an ssh client to connect to the machine (which will use port 22) - if sshd is running on the target machine you'll be able to open a secure shell.

If you want telnet to run on the target machine, check its /etc/inetd.conf file and see if the telnetd line is commented out. If it is, uncomment, and send a SIGHUP to inetd. I'd suggest you use ssh (protocol 2) anyway, telnet isn't very secure at all!

Cheers
