2008/8/5-10 [Computer/Networking] UID:50788 Activity:nil | 8/5 It looks like my company has started blocking HTTPS tunneling.
I used to do this by tunneling SSH through the HTTP/HTTPS proxy
server, but this seems to have stopped working. Does anyone know
how the implementation of tunneling detection works, and whether
there are widely available implementations? We run a bunch of MS
stuff, so I imagine we're running an MS proxy server or something.

\_ AFAIK, probably be corrected by someone:
hub: Allows communication on a LAN with bandwith shared amongs all
the nodes on the hub and maxing out at the max line speed.

the max line speed (point to point)
