To configure a two-way SSH tunnel, follow these steps:
1. Start by opening two terminal windows on your local machine.
1. In the first terminal window, enter the following command:
`ssh -f -N -R 2222:localhost:22 remoteuser@remotehost` This command creates a reverse tunnel that forwards all traffic from remote port 2222 to your local port 22.1. In the second terminal window, enter the following command:
`ssh -f -N -L 3333:localhost:2222 remoteuser@remotehost` This command creates a forward tunnel that forwards all traffic from local port 3333 to remote port 2222.1. Now you have a two-way SSH tunnel set up. You can test it by opening a third terminal window and connecting to the remote machine using the following command:
`ssh -p 3333 localhost` This command establishes an SSH connection to your local machine, which is then forwarded to the remote machine through the two-way SSH tunnel.1. You can also use the two-way SSH tunnel to transfer files by using the scp command. For example, to copy a file from your local machine to the remote host, use the following command:
`scp -P 3333 myfile remoteuser@localhost:/path/to/destination` This command copies the file myfile to the remote machine through the two-way SSH tunnel.
