=====================================================
``tperimeter`` - A Dynamic TCP Wrapper Control System
the ``tperimeter`` web interface. You also cannot specify
the host from which you desire access by using its name, only
its full IP quad address.
 
5) When initially logging into the ``tperimeter`` interface,
the user probably does not know their "real" dynamic IP
address - i.e., The address they need opened by ``tperimeter``
for the desired access. The dynamic IP addressing systems
found in hotels, airports, and self-service kiosks vary
considerably in their use of ``NAT`` and other address translation
schemes. There is a trivial solution to this problem, however.
Each time you log into the ``tperimeter`` system, simply
submit the request without the address field filled in.
``tperimeter`` will report an error that includes the address
the request came from. This is almost always the correct
address to use. If you are in a given location for several
days, be aware that many dynamic IP systems assign a new address
each time you log in. So, the address you provided on your
first day at a hotel may not be the same one the next day.
For this reason, the "trick" described above should be done
every time you log into ``tperimeter``.

There is a trivial solution to this problem, however. Each time
you log into the ``tperimeter`` system, simply submit the request
without the service or address fields filled in. ``tperimeter``
will automatically generate a request for ssh access at the
current address through which you're connecting. (It determines
the address from the http headers which is almost always the
correct address to use.) This makes it simple to just hit ``Enter``
at the ``tperimeter`` entry screen and have the right thing happen.
