You can use the kernel's IP firewalling mechanism to control which
systems can use the server as a relay. You would still need to write
some sort of `logon server' to enable and disable the firewall rules,
although this could be a simple script which functions as a login
shell (which would be accessed via telnet), or as a CGI script (which
would be accessed using a web browser).
