Having trouble interacting with text based UI

[Robert Butera]

Hi,

I am attempting to use sshj to automate a text based UI that is accessed via ssh.

Using sshj, I am successfully able to authenticate, navigate through a couple of menus, but when I hit a certain menu I am unable to get a response from the server no matter what I send.

This occurs when I use the SSJ rudimentary PTY console provided in the examples.  It also happens when I use ExpectIt (https://github.com/Alexey1Gavrilov/ExpectIt) with SSJ and it occurs when I use JSch.  So there is almost certainly something i'm doing wrong, I just don't know what it is.

If I use command line ssh I have no problems navigating past the menu.

I am looking for any guidance as to how I can diagnose the problem and move forward.  Any thanks would be greatly appreciated.

Hi Robert,

What are the (verbose) logs when using regular command line ssh? And what are the trace logs of using sshj?

Regards,
Jeroen

Hi Jeroen,

You can find both the sshj trace logs (using the rudimentary PTY example) and the verbose command line logs here:

https://gist.github.com/RobertButera/c0d43a124b5b7b19d10f763d301c31ba

In both cases I navigated to the menu in question.  With the command line I was able to get past it, with sshj I was not.

Rob

Seem to have worked this out.

Using sshj with expectIt I was able to navigate past the menu.

The important thing was to send carriage return - line feed on each command.
