What's New

This is the initial public release of 'tperimeter'

What Is 'tperimeter'?

Have you ever been away from the office and needed, say, ssh access to
your system? Ooops - you can't do that because in your zealous pursuit
of security, you set your tcp wrappers to prevent outside access to all
but a select group of hosts. Worse still, everywhere you go, your local
IP address changes so there is no practical way to open up the wrappers
for this situation.

'tperimeter' is a dynamic tcp wrapper control system that gives you
(limited) remote control of your tcp wrapper configuration. It does this
via a web interface that you've (hopefully) secured with https/SSL. You
just log in, specify your current IP address and one of the services you
want to access. 'tperimeter' will then briefly open a hole in your
wrappers long enough to let you in. It then automatically closes the
hole again. Voila! Remote access to your system, wherever you are. You
get much of the facility of a VPN or so-called "port knocking" without
most of the aggravation. As a side benefit, 'tperimeter' will also
simplify management of your standard /etc/hosts.allow tcp wrapper
control file.

'tperimeter' is written in python, shell script, and html. It is very
small and easy to maintain. It was developed and tested on FreeBSD 4.x,
and apache 1.3, but should run with very minor (or no) modification on
most Unix-like systems like Linux or Mac OS X hosts. It comes complete
with documentation in html, pdf, dvi, and Postscript formats. There is
no licensing cost for individual non-commercial use.
