After searching high-and-low for this fix, I finally found it’s fix…
HOW TO FIX “Algorithm negotiation failed”, the easy way:
when ssh to a system. In my case it was vCenter 5.*
- Use a different system or the console to drop to a shell.
- Edit the “/etc/ssh/sshd_config file
- Comment out the line reading “#Ciphers aes256-ctr,aes128-ctr” and “#MACs hmac-sha1“
- Restart your sshd service.
This removes the incompatible ssh Ciphers from your server.
USE WITH DISCRETION!!!
