It is quite common that the login of the root user is prohibited. Usually normal user accounts log in and are then allowed to become root. Issue an

Code:
lsuser root

and have a look at the user attributes. Alternatively do a smitty chuser and check there.

Bind to port 22 on :: failed: The socket name is already in use..
Cannot bind any address.

This seems to be pretty obvious, doesn't it? Whatever occupies port 22 either has to go or you will have to use another (unoccupied) port for ssh.

I asked you to remove the comments and i really did mean it. It seems that PermitRootLogin yes is not set at all and other relevant parameters are not set either.

Correct your sshd_config (you can find many examples for AIX here in this board) and then restart your ssh-daemon. Btw., newer versions of the sshd (you still haven't told us which version/package you are using) are controlled via the systems resource controller: instead of starting it from the command line you do a:

Code:
refresh -s sshd

or, if it is not started (check with lssrc)

Code:
startsrc -s sshd


I hope this helps.
