SSHD - authenication issue

[pbaker]

i have been using putty to ssh into a centos box. i think i changed the authication on something and now if i try to connect i get the login box to type in a username but then i get an error that says no authenication method supported is there anyway around this or an option to change

It sounds like you locked yourself out.

So you might need to get a local console on that machine to revert the changes.

i did wonder this, but wasnt sure if there something else i could do like a backdoor to gain entry and fix the problem i made as im not near the server at the moment. if not i will have two wait until im back home in a few days to fix it then.

Not to be mean,
but I wouldnt use opensshd, if it had such a backdoor

Maybe this machine features (and is already configured to use) some out-of-band management?

i did think that and i understand they wouldnt really do it because of security
