Question : Problem: Telnet Script to Test Connectivity

HI,
I am having some connectivity issue to a remote host and would like to be able to make a scheduled task that tests connectivity via telnet. Basically, it would run every 5 minutes (terminate after 60 seconds if successful) and if it fails, it would output a message to a txt file on the local machine. I have a remote monitoring tool that sniffs for this error entry every 5 minutes.

Breakdown
Every 5 minutes - telnet remote.host 8075
If success, connection closes after 60 seconds untl the next test.

If it fails, it will output "Connection to host failed" to a txt file on the local machine.

I am having problems getting a start on this, mainly the scripting to close the connection after 60 seconds. I do not want 100+ open telnet tests at the end of the day. Any assistance is greatly appreciated.

Thanks!

If you just want to check if you check if the port is opened/closed, you can download portqry from
