$ ssh -i ~/.ssh/SSH-EC2.pem - system, cmds & shell To make it easier to ssh to remote, we set up an alias as "ec2b" in ~/.ssh/config like this:

So, the syntax of the full command would be as follows: The channel between "remote" and "local" will be encrypted while the connection between "remote" and "" will be unencrypted. So "local" doesn't need to know how to connect to "". At the "remote" end it will create a connection to "" at port 80.

Now the SSH client at "local" will connect to SSH server running at "remote" (usually running at ssh port 22) binding port 9001 of "local" to listen for local requests thus creating a SSH tunnel between "local" and "remote". $ ssh -L 9001::80 L switch indicates that a local port forward is need to be created. To simulate the picture, we'll use EC2 as a remote and my home computer as a local: They are also called outgoing and incoming tunnels, respectively.

There are two kinds of port forwarding: local and remote forwarding.
