I have a Linux box I need to remote into.  SSH is running and I can get a prompt remotely, but I can't login.

I tried seeing what is up with sshd_config, but the lines are completely commented out (I did a search and found two - both the same)

So if it's using a different config file, how can I find it?

Are you trying to login as root? If so then direct root login may be disabled.

Do you have a console plugged into this Linux box which you are able to use or is the machine remote as well?

I'm trying to log in as a regular user whose logon works from the physical box

I can get to it locally.  But the sshd_config files is commented out entirely.

I don't see how sshd can run if every line of it's config file is commented out, as I have no problem getting a remote prompt,  so I'm wondering if it's referring to a different config file and how I can find it?

The configuration file should be /etc/ssh/sshd_config. Is this the file that is commented out?

If every field in /etc/ssh/sshd_config is commented out, then sshd will be using all the defaults.

What message do you get when trying to login?

What message do you get when trying to login?

Try running sshd in debug mode then try logging in again.

Ahh!  While I was at the terminal, I tried to ssh to 127.0.0.1,

I get the error. "Permission Denied (Public Key)"

I'm guessing it's a public key authentication thing.

How can I disable Public Key authentication so I can use a regular user-name and password?

 Post your ssh config file, what distro are you using?
  In the sshd_conf file you should see an option for passwords, make sure you can log in using passwords.  If you post your sshd_config I am sure someone here could pick it apart.

try logging in with the "-v" option to get verbose output on the client side

if the result isn't giving you enough clues you can post it here for comments

you can also try to start the server with the "-d" option to get debugging output (probably to syslog)
(the ssh server needs to be restarted after each login attempt when "-d" is used)
