Too Amany Authentication Failures, when I ssh into a server
I get the error "Too many Authentication Failures" when I ssh into a server from a particular server.
If I ssh from server A to server Z I get the error Too many Authentication Failures
If I ssh from server B to server Z, no problem
It appears that the local sshd on server Z does not like server A.
I changed the option in /etc/ssh/sshd_config MaxAuthTries from 1 to 5 and I can now login to Z from A. That does not tell me why the problem existed in the first place. Why would sshd not trust a particular server?
