[How-to] SSH tunnel && port forwarding

Short for Secure Shell, SSH (developed by SSH Communications Security Ltd.) is a secure protocol for remote logins. Using an SSH client, a user can connect to a server to transfer information in a more secure manner than other methods, such as telnet. The image to the right is an example of how an SSH session, which uses a command line interface, may look. SSH defaults to port 22.

SSH option:

• Dynamic port forwarding
  Command:
  

  ssh -D [bind_address:]port

   

   

  Example:

  ssh -NfD 0.0.0.0:ASocksPort ddos@BIP -p 22
  ssh –NfD 0.0.0.0:ASocksPort ddos@AIP –p ATunnelPort

• Reverse port forwarding
  Command:
  

  ssh -R [bind_address:]port:host:host_port
