When I try to ssh to a remote computer I get the following error:
Received disconnect from RemoteIPAddress: 2: Too many authentication failures for UserNameA
However until recently this used to work fine. I asked me for a password and I could login. It seems like I messed up my ssh configuration. Maybe by following this website which recommended using some ssh - agent...
Does anyone know how to repair my ssh configuration to the normal setting. This is the output of ssh -v UserNameA@RemoteIPAddress
ssh -v UserNameA@RemoteHostName

I tried manipulating /etc/ssh/sshd_config
and calling sudo /etc/init.d/ssh reload
:
RSAAuthentication no
PubkeyAuthentication no
[...]
PasswordAuthentication yes
But it didn't help :-/
