Description

Please implement and integrate a GUI for port knocking
to make PK easy and convenient to use. PK adds a
simple but effective layer of security.

http://en.wikipedia.org/wiki/Port_knocking

I imagine the PK GUI to be able to use/add/edit/delete
a list of port knocking "sequences." Each sequence has
one title, one host name, and then an arbitrarily-long,
ordered list of port numbers and protocols (TCP or
UDP). So, a sequence might be:

Title: The office LAN
Hostname: office.example.com
#1: UDP 12898
#2: TCP 62181
#3: TCP 9999

You could also design the UI for the sequence as a
string...e.g.
udp:12898 tcp:62181 tcp:9999

Several applications have integrated port knocking
clients. For example, Enhanced TightVNC has it, and it
will also be in an upcoming AlmostVPN (for Mac) and WinSCP.

I'd like to find a way for people at our office to
access our Linux file server from home using their
Windows computers.

Won't be implemented. Port knocking is a superflous concept.
VPNs and a good password / public key authentication scheme
can do a much better job.
