Title: SSH Connection fails after update to OpenSSH 7.5
Post by: dbonine on May 03, 2018, 10:51:44 am

We have recently applied a security update to AIX to use OpenSSH 7.5. The update is causing all ssh connections from ICETCP Pro DejaWinT to be disallowed. I have made the suggested change  to the sshd_config, but that does not work. We are using ICETCP 4.4.30. TCP PRO 5 doesn't work either. I have tried the newest version of TCP PRO 5.1.30 and ICETCP Plus build 30 without success. I get the ssh login box, type in the credentials and the window disappears with no connection.

I am able to make SSH connections with PuTTY and other emulator evaluation software.

As in the ICE TCP Plus post, use this in your sshd_config file (and restart sshd).
