SSH tunnels

  1. This tutorial helped understanding tunneling a little
    • Main example is:
       ssh -L 8888:localhost:7180 remote.server.com
      

      In this example we assume that remote.server.com has a website available like this: remote.server.com:7180. After entering the above command we can also access this website with address localhost:8888. This is very useful when for example we cannot connect to port 7180 because of network configuration in the remote.server.com.

    • How this works
  2. How signing of files/other information works
  3. This information was very useful to understand ssh
  4. SSH encryption description, ssh agent. Super good
