This looks like you have a bad cable perhaps.  Does the disk seem to 
work ok after these errors come up?  It could also be an indication 
that your disk is dying.

sshd is started in the default install.  The configuration of sshd is 
controlled by the file /etc/ssh/sshd_config

There are a lot of really cool things that you can do with ssh, but 
out of the box you should be able to log in remotely by doing:

$ssh -l usernameofaccountonthehost hostname

man ssh and man sshd have lots of useful information on ssh.  A book 
that you might get if you are interested in all of the things that you 
can do with ssh is Using Secure Shell Services by O'Reilly.
