Situation
This article discusses information regarding following error:
Unhandled Exception: Exception: Failed: uname -q ---> PlateSpin.OperationsFramwork.PlateSpinException: Access denied to SSH server on x.x.x.x when connecting as serveradmin ---> Maverick.SSH.SSHException: Failed to negotiate a transport component [3des-cbc] [aes256-ctr]..........
When performing discovery on a Linux workload
Resolution
We currently only have a work around:
comment out all cipher related line in /etc/ssh/sshd_config, for example:
# default is aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,
# aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,aes192-cbc,
# aes256-cbc,arcfour
Then re-start sshd:
/etc/init.d/sshd restart
Cause
Customer tightened ssl security by removing some ssl ciphers.
