This command will create a dynamic forward from an SSH client to an SSH server. Basically what this does is allow you to use any local port (8080 in this example) as a proxy for any TCP application.

Feedback, suggestions and comments are all welcome!

# In the following example, we create a dynamic
# forward from port 8080 (client) to port 22 (host.net).

ssh -D 8080 username@host.net

# Now, we'll check out netstat to see what we
# have done.

netstat

# Active Internet connections (w/o servers)
# ...
# tcp 0 0 host.net:ssh client.com:60565 ESTABLISHED
# ...

# Awesome! Now we've got the connection. I'll add
# another post telling how to use this port as a
# socks proxy for any TCP application :)
