If you've got ssh running on the machine, and you don't want to enter
a password each time, just use RSA authentication....

On the server run ssh-keygen (hit return when asked for a password -
gives an empty password on the RSA key).
This should give you ~/.ssh/identity and ~/.ssh/identity.pub files.

Copy ~/.ssh/identity.pub to ~/.ssh/authorized_keys on the machine you
want to login to.

I've got 3 machines that have been running without a monitor, keyboard
or mouse since they were rebooted after installation.
All of them are controlled over ssh - none of which require a password
to login.

Dunno if my explaination is clear so....

Example - as baz [at] flux.localdomain, I want to login as
root@noodles.localdomain, via ssh, without using a password...

As baz, on flux.localdomain:

ssh-keygen
(when prompted for password/confirmation hit return)
scp ~/.ssh/identity.pub root [at] noodles.localdomain:~/.ssh/authorized_keys

(enter the password for root on "noodles")

ssh root [at] noodles

(Viola! Root prompt on noodles)...

It's all in man ssh / man sshd

About the only thing that throws a spanner in the works is the file
permissions on the various files - check the man pages, but it should
all be setup OK as standard.

I dunno, am I missing something that everyone else hasn't commented
on, or have I got the wrong end of the stick (again)?

Cheers.

Baz.
