SSH tunneling is essential for secure remote access to data. This guide briefly covers what SSH tunneling is, its uses, and some common issues users might face.
Examples of SSH Tunneling
Creating an SSH Tunnel:
ssh -L 8080:remote_server:80 user@ssh_server
This sets up a tunnel from local port 8080 to remote port 80 through the SSH server.
Reverse SSH Tunnel Example:
ssh -fN -R 7777:localhost:22 user@remote_server
This command creates a reverse tunnel from the remote server to the local machine.
