The thing is, when You are at that remote location, how would You know
the address that Your box currently has (since it will change from time
to time, as You know).

There are other ways to do this than with dynamic DNS, like having it
sent to You via e-mail or some paging device such as a cell-phone. But
using dyndns or the like has the advantage that You only have to remem-
ber one name that You registered Yourself with.

Of course it is. - If You know the IP that You currently have, just
go "ssh user@$IP_ADDRESS", and Yo're done. If You use dyndns, it's
like "ssh user@yourname.dyndns.org". - You should not allow telnet
from the outside if You have ssh.

To clarify this: Your problem is to determine what dynamic IP address
Your ISP gave You, especially if it changes while You're not at home.
Once You have that address (because You got it by e-mail or via some
dynamic DNS service), all services that Your box offers are available
from the outside, unless You block connection attempts via some fire-
walling mechanism.

Cheers, Jack.
