Greetings from the Extreme Markup Languages Conference in Montreal.
(Which is a great conference but it's not what this note is about.)

Here I am at the Europa hotel with pretty good internet service.
Unfortunately, as in most such away-from-home situations, there's no
way for our amanda server to contact my machine after midnight to do
the usual daily backup.

I'd like to do the backup anyway.  I was wondering whether I could set
up an ssh tunnel at bedtime for the backup to occur later at night,
and I came across

http://wiki.zmanda.com/index.php/Amanda_and_ssh_tunnels

...which suggested that this is indeed possible to do, but it doesn't
account for the fact that our amanda is configured to use ssh.

I did what the article said to do (well almost -- what I really did
was:

   ssh -l 10080:<server>:10080 <server> 'sleep 7000' &

) but when I ran amcheck on the server (using another ssh session) it
couldn't find my machine, even though a tunnel presumably existed.
Amcheck, running on the server, said it couldn't find my machine at
port 22.  Whereupon it occurred to me that 10080 is not the same as
22.  (We use auth-ssh.)

Any clues to offer?
