Try ssh with the -v option (verbose) and post the last 10 or so lines
that you get.

What means "doesn't seem to work"? There could be several
things that lead to failure. e.g.

a) There's no ssh daemon running on the remote machine
b) There might be a firewall in between that blocks con-
nections to port 22
c) remote root logins may not be allowed on the remote
machine

Of course it's totally k-rad fancy cool for the beginning user with
his own linux box to login and do everything as root.

This, however, is bad practice; it's unnecessairy and dangerous. Of course
every windows user on his own windows machine does everything with admin
rights too, but we all know about the gigantic botnets Out There. Had all
those users done the sensible thing and given themselves two accounts: one
to use, and a separate one with a (different) password, and admin rights
only to be used when strictly necessairy, then all that malware would have
had a manifold harder time gaining any foothold.

So, don't do that. Use your own user account and use su or sudo to gain
root if and only if you need it. In fact, any sensible unix and linux
distribution comes with its sshd defaults set to disallow logging in as
root. If you insist you now also know where to look to enable this, but
you can't say you haven't been warned of possible dire consequences.

Try logging in as someone other than root. Some systems specifically
disable remote root logins for security reasons.

P.S.: When posting a technical question like this, it's best to provide
a more detailed description of the problem than just saying "it doesn't
work." What happens *exactly*? Does the action eventually time out, or
do you see any error messages?

Right. The unix machine (and certainly should, although it's not the
default setting) may have "PermitRootLogin no" in the sshd_config
file.
