You can accomplish this using a config file in the _client_ host, ie: user@client ~ # cat .ssh/config Host remotehost Localforward 20000 localhost:20000 # ssh remotehost (connect to port 20000 on clienthost and your connections will be crypted :-)) HTH [Jack Allen] Thanks for the information, but I think you have misunderstood my requirement. The Application cannot execute ssh, it must just establish a plain TCP connection to a local TCP port and then have a program automatically start a ssh connection to the remote system. And user will be doing this through the Application and the Application will automatically do it at scheduled times. So it needs to look something like this. Application <-simple-> (Local TCP port, Program or ssh) <-secure-> Remote System ----- Thanks: Jack Allen -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
