SSH via HTTP - proxytunnel
SSH via HTTP — proxytunnel Excerpt SSH is a hugely powerful tool for communicating with and manipulating remote machines, and as a result many companies fear it and try to block it. As such, many corporate firewalls block port 22, the port naturally used by SSH. However, few corporations can afford to block ports 80 or 443, the ports designated for http traffic. SSH is a hugely powerful tool for communicating with and manipulating remote machines, and as a result many companies fear it and try to block it. As such, many corporate firewalls block port 22, the port naturally used by SSH. However, few corporations can afford to block ports 80 or 443, the ports designated for http traffic. It is possible to work around these firewalls by configuring SSH to listen on either port 80 or 443. However, this approach is only suitable if you are not already using, or planning to use, port 80 or 443 to serve your websites. There is, however, another option. If you have are running an Apache webserver, you can configure it to act as an HTTP or HTTPS proxy and use it to forward SSH traffic that comes in on ports 80 and 443 to your SSH server.
