Have you considered "port knocking", which is similar to what
your describing.
Hi John,
I was not aware of the port knocking, but it seems as near as dammit
identical to what I had in mind. I "invented" it too late!!
On thing that stuck me as odd reading one of the articles on port knocking
http://netsecurity.about.com/gi/dynamic/offsite.htm?zi=1/XJ&sdn=netsecurity&zu=http%3A%2F%2Fwww.linuxjournal.com%2Farticle.php%3Fsid%3D6811
is that they say you have a limited number (about 256) ports available.
But they seem to be considering only privilidged ports below 1024. I
can't see why as in my original idea you can't use ports above that. Not
that I feel there is any need to use 256 ports, but I don't know why
they think why that is a limit.
Perhaps it explains it somewhere. There were so many flashing graphics I
got fed up reading it, so went elsewhere.
