Whenever
you run a server on your machine, it uses what are called 'ports',
which allow other machines to connect to them. Of course, sometimes
you're just running them for your own internal use, but there's no easy
way to stop someone from accessing the server. AnalogX PortBlocker
allows you to basically block the Internet port of most servers, making
them unreachable to other computers on the Internet. This program is
NOT a Firewall, but it will allow you to run a server that is only
available on the local network, and will log any access attempts made
by other machines that are attempting to use the blocked interface. By
default, PortBlocker is configured to block the most common types of
servers that might be on a system (FTP, HTTP, etc), so will not require
any modification for most users. If you are running a special server of
some sort, then you can easily add it's ports (either TCP or UDP) to
it's list, and have them blocked and/or logged.
