I just came across something strange with my fully updated
Centos7
server. When I try to ssh into it the same way I've always done I
get
"Too many authentication failures". This just came out of the

I'm
using the root account and a password. But in my sshd_config it
still
reads
#MaxAuthTries 6
Which I think is the default.
From the console I can log in fine and when I look in the logs
for
sshd
I can just see the the attempts I just made, that are less than
six
and
no previous denied attemps.
Any clues what's going on?
I got the same error once.
In my case the problem was ssh tried to log in with ssh keys before
giving a password prompt.
Thanks, same for me. I had added a new key for a different server to
the ssh client machine that got it over the limit.
This got me wondering what is the best practice for a situation where
you have a machine with more than five keys on file in able to ssh to
different servers. But you would also like to ssh with password to an
other set of servers.
I would suggest to configure your needs in .ssh/config
Check man ssh_config. Example:
#.ssh/config
Host myhost.example
PubkeyAuthentication yes
User myuser.example
IdentityFile ~/.ssh/mysecretkey.example
Host *
PubkeyAuthentication no
Just to get the idea. Top-down, first entry win, last is the default.
