![]() ![]() Putty (which may be available on your Intranet, if you’re lucky). ![]() Amazon AWS account (sign up for free – you won’t be charged until you use it).In steps 14-16, we’ll configure the browser to use the Putty as the SOCKS server. Read how to set up Putty as a SOCKS server and how to use Putty with a HTTP proxy. In Steps 8-13, we’ll set up Putty as our local HTTPS server. Alestic’s article on how to Automate EC2 Instance Setup with user-data Scripts and this thread on running SSH on port 443 are invaluable. (Remember: most proxies block all ports other than 80 and 443). Step 1 enables Port 443, and step 6 re-configures SSH to run on Port 443 instead of on Port 22. In Steps 1-7, we’ll launch a server on Amazon EC2 with 2 tweaks. So here’s a 16-step recipe to bypass your web filter. Amazon EC2 gives us a server outside the firewall. So we can redirect web traffic to a local HTTPS server, and set up a server outside the firewall that redirects them back to the regular servers. That means web filters can’t really block HTTPS traffic. Since all the traffic that passed through the tunnel is supposed to be SSL encrypted (so as to form an unhindered SSL session between the browser and the HTTPS server), there are little or no access controls possible on such a tunnel But it’s used to carry encrypted traffic, and, as Mark explains: Most web filters and proxies block all ports except the HTTP port (80) and the HTTPS port (443). And I usually end up wasting that money anyway on calling someone or eating my way out of the misery of corporate proxies.) It’s a fraction of the cost a phone call or a sandwich. You can defeat most web filters by spending around 8 cents/hr 0 cents/hr on Amazon EC2. ![]()
