[PLUG] Putty on Windows - Getting around the Firewall to All Servers (Samba, Mail, Http)

[Mike Chirico <mchirico@comcast.net>]

Many people run Putty on Windows to connect to their Linux
computers at work or home. If your firewall only permits
port 22 (ssh) to a single computer, it's still possible to
get access all the other computers on that network. That
could be a good thing.

This article shows how to connect a WindowsXP computer
to multiple samba shares, mail, and an http server 
normally blocked by a firewall.

To me, this method shows the power of sshd running
on a Linux server. No need for an expensive Microsoft VPN 
solution (PPTP ) that runs  much slower than the
ssh method in the article. In addition, Microsoft's VPN
PPTP solution requires protocol gre 47, which some ISPs
may not route. Some Virizon locations are blocking gre 47.

The method can be used in reverse - if you are forced to
use Windows at work; but, want full access to your home
Linux resources, this method should work as well.

You may want to reference the following resource (TIP 13)
on how to secure the ssh server so that root cannot login
remotely.

Also, (TIP 12) will detail generating ssh keys.
