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. Any idea
what is happening?
