Server initiated remote shell

[Ilici Ramirez <ilici_ramirez () yahoo com>]

Hi,

Lets suppose that I can execute a program on an inside
host on a network protected by a firewall. There is no
way in. But there is a way out to www browsing on port
80.

So the client could connect to any Internet address on
port 80. What program should it execute to provide me
with a shell? Of course I'm in Internet with a
listener. What listener?

The firewall is a real statefull firewall so no TCP
ACK or ICMP encapsulations. 

Have a nice weekend too.

Ilici R
