ACE probe to test telnet

Is there a way to create a probe in the ACE that can telnet into a rserver login with a uid/pass and pass the probe when a expected return message is sent back from the rserver?  I have been looking into way to do this for days.  I thought I might be able to create a tcl script for it, but have had no luck.  Then I thought I could modify the imap probe but I keep getting an error "Invalid server greeting" in the probe state.  Has any one done this type of probe or can point me in the correct direction?

Re: ACE probe to test telnet

The problem is that the telnet protocol use some communication parameters negotiation before you can start transmitting your text.

You need to take into account when designing your tcl probe.

The best is to capture a sniffer trace going to your server, extract the negotiation part and replay it from within your probe.
