From: pranav jituri To: cygwin AT cygwin DOT com Content-Type: text/plain; charset=ISO-8859-1 X-IsSubscribed: yes Hello, I am behind a firewall and a proxy. The setup is like I enter the proxy and the port to connect to the Internet which is then again filtered. Now, I did some research for this and found how to do it. I was successfully able to tunnel to the Amazon EC2 instance on port 443, but due to bandwidth limitations of free tier, I purchased an instance on DigitalOcean. Now, the problem is that this present server is also has it's SSH Daemon listening on port 443 but I am receiving a Proxy could not open connnection to aa:bb:cc:dd: Proxy Authentication Required ssh_exchange_identification: Connection closed by remote host I am currently running Cygwin under Windows 8. At the moment I am able to SSH and tunnel into my Amazon EC2 instance but not into this one.
