Re: bypassing employer's proxy to surf anonymously

Gimeshell,

If a network is being used to transfer traffic, and something is physically
monitoring all traffic (regardless of source/destination port, regardless of
protocol, etc) then there's no way to prevent them from monitoring your
traffic over that network.  You're talking about bypassing something in a
lower network layer (physical) with something in a higher network layer (i.e.
Data or Network).  It's not going to happen.

Now hiding data in unsuspicious packets....depends on your definition of
"unsuspicious" and the level of detail of the network admins are who are
monitoring the traffic. If the net admins are using a network forensics
analysis product you have to get fairly creative to hide your data.

Question:

Is there a solution to prevent proxy traffic monitor (and therewith
big brother) to see SSH traffic to dynamic ip? So that there isn't any
suspicious line in proxy traffic monitor's output? The best: Proxy
doesn't get notice of nasty traffic at all.

Perhaps there is some technique to hide data in unsuspicious packets?
