Dear Gentleman,
Could someone please advice me as to how I should telnet continuously to a certain port on a server from a remote machine in order to determine if there are any disconns. Preferably I'd like to take the incoming telnet stream to a file at the server end and check if there are any disconnections. Heard this can be done with the use of "nc" ? If thats case the would someone please help me out with the steps.

For an instance say my server IP which the clients are connecting to is 212.*.*.* and the port is 7005. Please help out gentlemen.

Many thanks in advance

Cheers
Vimo

By disconns do you you mean network connectivity, or the server shutting down active connections due to crashing or something?

You could use nagios to verify network connectivity and server response.

Like frndrfoe says, nagios is a good choice but of course there are simpler monitoring tools to configure, like monit or big brother.

As you asked, nc or netcat can monitor the port for a connection.

nc hostname port

echo command | nc hostname port
