Unable to ssh as regular user

[audiodef]

I'm unable to ssh to a server as a regular user, but I am able to as root. Has anyone else experienced this problem?

What exactly happens?

If you open a terminal and type

ssh user@machine

What is the output?

OP: do you mean that running /usr/bin/ssh as a normal user fails, without regard to the login name on the server, or do you mean that /usr/bin/ssh user@server fails, without regard to the UID of the ssh process on the client?

Aha. Using ssh user@host works. I was just using ssh host. I'm guessing it's a security issue that it works this way.

Normally, if you don't specify user@, ssh will use your current user name, which means you should have a user with the same user name on the remote machine.

I've never heard about requiring user@ as a security measure.
