Porter,
Thanks very much, both of them are working good. But the problem is when there is no connectivity

telnet 10.2.89.94 1234 </dev/null
Trying 10.2.89.94...

It is still waiting on here if the connectivity is not present. Is there any way of bypassing even this.

It should time out after about 3 or so minutes. That's TCP doing what it's told to do.

Er, don't run telnet?

How about ping it first?

Porter,
Ya if as you said it is what telnet has to do, I am actually using a script to check the connectivity for more than 20 machines, and if there is no connectivity present then the script will hang over there until the limited time as of 3 min or so. I actually wanted the script to go on with the next line in the script even when there is no connectivity found.
