The method I used to skip a bastion was (while still using HTTPS "CONNECT")
to run pppd in inetd on 443/tcp ... then all you need to do is run the ppp client 
over the "telnet" session and you can fully route one organisation through 
another.  At the time I used cotty to dup the tty at the client, but netcat should
be better for this now.

That is very easy if you can have a machine in the net with ssh server...

With a standard proxy that support CONNECT METHOD (Typically HTTPS
connections) using putty and a ssh server listening in port 443 you can
forward any port via tunneling.

Look at your logs looking for an endless HTTPS connection..., with tons of
traffic.

Subject: By passing surf control

Hello Group,


Does anyone have any information on how to by pass a web content filter? We
use Surf Control to monitor and filter web content. However, I have one of
my users who was able to by pass this. We tried using a proxy to by pass
just for testing purposes but it did not work. I am still trying to figure
out what other method he used to do so. If anyone has any information , it
will be greatly appreciated.

Thanks

Kuda
