Environment
UNIX Manager 5.6
UNIX Manager 7.1
Vmware ESX Server
Not VMware ESXi server
Situation
While deploying to ESX hosts through the UNIX Manager you might receive:
com.jcraft.jsch.JSchException: Algorithm negotiation fail
com.jcraft.jsch.JSchException: Algorithm negotiation fail
Resolution
To fix this issue:
1) find and comment out the following line in the /etc/ssh/sshd_config file:
Ciphers aes-256-cbc,aes-128-cbc
2) Restart the ssh server:
/etc/init.d/sshd restart
Cause
Some versions of Vmware ESX server limit the possible ssh ciphers to a set which the UNIX Manager does not support.
