telnet session in background...

[simpson]

I am attempting to fire up a telnet session in the backgroud via a script. I am not needing to log into the session only to establish the session and create the telnetd process on the remote machine. REASON FOR SCRIPT - I am updating the kernel parm for the number of allowable telnet sessions and want to start up a whole bunch at once. Problem is when you try ( telnet server_name & ) it starts the session but you need to hit enter. I have tried many different string sequences in my script but nothing seems to work. ANY IDEAS???

Thanks
Simpson

You could start it as a coprocess...

#!/bin/ksh

telnet someplace.domain.com |&

print -p ""

The "[tt]|&[/tt]" starts the telnet as a coprocess. A "[tt]print -p[/tt]" will send commands to it, and a "[tt]read -p[/tt]" will get the output from it.

You can only have one coprocess that you can talk to at a time, so this might not work for what you're trying to do.
