[aclug-L] Re: Encrypted/compresed network traffic

["John Alexander" <johnalexander@xxxxxxxxxxx>]

Ah, use one compression engine on either end of the link that feeds the hub
that interconnects the three machines.

  +-c/e--the 'Net--c/e--hub--+-----+-----+
  |                          |     |     |
pc(a)                      pc(b) pc(c) pc(d)

An alternative would be to build the compression engine with whatever might
be in the van o' junk and computers to interconnect these segments. You
could use the built-in compression and port forwarding capabilities of ssh
to do this. That just sticks in my head because I learned how to send a vnc
screen over a compressed ssh tunnel last night.

It'd be easier to use something intended for full network tunneling, such as
IPSec or VTun.  But my goal was to find something that didn't require a
point-to-point connection for security.  I suspect that nothing like that
exists.
