SSH Password Authentication

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View

I logged in from SUSE 9.3 Server via my shell to a UNIX Backup Server.
The authentication method is with a password. After the first login, I
never was asked again for the password on the UNIX Backup Server. The
log in worked without any authentication!! Is there something like a
password cache? I use OpenSSH.

Not as such, no.  There are however several authentication methods which
will allow you access without asking you for a password.  You can see which
is being used by using the "-v" option to ssh.

It's also possible to misconfigure your system such that no authentication
is required (eg by messing with the PAM config files, or setting an
empty password and enabling PermitEmptyPasswords in sshd_config).

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.

Host-based authentication might be the problem.  Maybe it's activated,
so the backup server remembers your hostname and lets you in without
password authentication.
