/sbin/ifconfig
will display the IP address of all interfaces
It would be really hard for those people to ssh in and read that file
unless they first knew the IP, in which case they wouldn't need the
file ...
Instead, check out ddt.sourceforge.net. It is a project that provides
a client utility that will update their server so you can have a
domain even though you have a dynamic IP. Then you don't need to know
the IP anymore.
