difference between ssh and openssh.  I have one EFT server that will accept SSH.
I have another EFT server that won't accept SSH, but will accept openSSH.
The servers are globascape but they are different versions.  The newer version will not accept SSH.
Thank you

    I don't think it's a matter of SSH compared to openSSH. More likely the problem you are having is which version of SSH are being accepted. By that, I mean the version of the protocol. If you are using version 1 of the protocol on one machine, and running SSH tries to only connect on version 2, then you won't be able to connect. On the other hand perhaps openSSH automatically tries version 2, and then falls back to version 1 if version 2 fails.

    You'll need to check the servers for what versions of the protocol they will accept.

    Show us the output of

    ssh - v eftserver1

    ssh -v eftserver2

    Using the SSH client.  It's probably more due to ssh server configuration, particularly around permissions.

    Really need to see the debug output from when your login fails with the SSH client.
