Any help wpuld be appreciated. You need to look at the logs or messages when you try to connect from SL7 to F28 (and F29 is current). Odds are that SL7 is using a cipher or an algorithm that is deemed insecure in the latest sshd implementations at the F28 end and you'll either need to have sshd on F28 accept it (via a "Ciphers" or "KexAlgorithms" option in /etc/ssh/sshd_config) or use one of the acceptable ciphers/algorithms at the client (SL7) end. Logs and error messages are your friends in these cases. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - "Hello.
