From yesterday, I cannot connect on a server. It's a rhel 7.1, properly installed 1 month ago, not special configuration.
I did have 2 logins: "root" and "parta". I've got both password, and both are not working anymore... But, I did not change anything, nor I someone else connected to this server.
There is the ssh -vvvv:
debug2: we did not send a packet, disable method
debug3: authmethod_lookup password
debug3: remaining preferred: ,password
debug3: authmethod_is_enabled password
debug1: Next authentication method: password
debug3: packet_send2: adding 64 (len 58 padlen 6 extra_pad 64)
debug2: we sent a password packet, wait for reply
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password
Permission denied, please try again.
I have a physical access to the server, so I can recover the root password (boot in recover mode), but I don't think it's only a "password" problem. Can it be something else ? (wrong permissions,..?)
