Strange behavior with version 7.21 11 Years, 4 Months ago  
We have been using Absolute Telnet for a few years and it is a very versatile product.

However, we encountered some strange behavior recently, and are a bit puzzled.

We have several customers that run legacy (CUI) applications, usually running on SCO Unix servers (using Procomm), which we have been converting to RedHat Linux (and Absolute Telnet). On a recent conversion to Linux, we discovered that, while logging in to the Linux server as "root" using Absolute Telnet v7.21 worked fine, logging in as a non "root" user would immediately disconnect. We scoured the AT connection properties, but nothing presented itself as being the problem.

Because I had several working (v 5.39) .tnt files on my PC, I modified one to use the hostname and port of the problem customer's Linux server, and emailed that .tnt file to my technician so that he could try the non "root" login. Interestingly, using this .tnt file (under AT v7.21), logging in as a non "root" user worked fine.

Are there any particular settings in AT v7.21 that we should look at to try to determine what caused this behavior?

Steve,

Are you using telnet, ssh1, or ssh2?

Hi Brian:

We are using SSH2.

Try disabling compression and changing encryption algorithms.

Also, check to make sure the version of the SSH server is up to date. This can be a huge factor sometimes. What ssh server version are you using? You can see the server version in Absolute by using Options->SSH Info when connected.

Hi Brian:

Thank you for the response.

I had looked at the Encryption and Compression settings, but didn't really know what I was looking at. I thought maybe it was something quick and simple we could change in the in the Properties.

Actually, we're pretty much under the gun to get this conversion complete before school starts, so I think we'll probably (for now) just propagate the working .tnt file, and look into the details later.

But thanks again for your help.

What you're looking for is whatever is different between the two, such as whether compression is on or off or what encryption algorithms are selected and what order they are in.

I understand you're in a rush, but this kind of thing would gnaw at my brain until I figured it out. Let me know if you get a chance to resolve this.

Did you ever determine the cause of this?

Hi Brian:

No, I haven't even looked into it yet. We are still heavy into the conversion at that site. Thing is, using a prior version .tnt file is working so smoothly, I may never take the time to look into the issue, unless someone forces me to. I have used AbsoluteTelnet so little myself that I'm don't feel knowledgeable enough to get into researching some of the more esoteric property settings (esp. SSH settings).
