<p>Do you need to admin remote host placed in the intranet behind firewall out of your control?
If the firewall performat NAT (masquerade) where you can connect from
the intranet to the outer world by @{[ a_href 'http://www.openssh.org/','SSH' ]}
you can use these security safe scripts.</p>
<p>If you are able to set up port forwarding on the firewall you do not need any such scripts.
In the case of HTTP-only proxy you cannot use these scripts - look elsewhere.</p>
