Create a new file " authorized_keys " (with notepad) and copy your public key data from
the "Public key for pasting into OpenSSH authorized_keys file" section of the PuTTY Key
Generator, and paste the key data to the "authorized_keys" file. Make sure there is only
one line of text in this file.
Use WinSCP to copy this "authorized_keys" file into the users home directory: eg.
/etc/config/users/testuser/.ssh/authorized_keys of the Console Server which will be the
SSH server. You will need to make sure this file is in the correct format with the correct
permissions with the following commands:
# dos2unix \
/etc/config/users/testuser/.ssh/authorized_keys && chown testuser \
/etc/config/users/testuser/.ssh/authorized_keys
Using WinSCP copy the attached sshd_config over /etc/config/sshd_config on the server
(Makes sure public key authentication is enabled)
Test the Public Key by logging in as "testuser". Test the Public Key by logging in as
"testuser" to the client device and typing (you should not need to enter anything): # ssh -
o StrictHostKeyChecking=no <server-ip>
To automate connection of the SSH tunnel from the client on every power-up, you need to
make the clients /etc/config/rc.local look like the following:
#!/bin/sh
ssh -L9001:127.0.0.1:4001 -N -o StrictHostKeyChecking=no testuser@<server-ip> &
This will run the tunnel redirecting local port 9001 to the server port 4001.
Fingerprinting
Fingerprints are used to ensure you are establishing an SSH session to who you think you are.
On the first connection to a remote server, you will receive a fingerprint which you can use on
future connections.
This fingerprint is related to the host key of the remote server. Fingerprints are stored in
~/.ssh/known_hosts.
To receive the fingerprint from the remote server, log in to the client as the required user
(usually root) and establish a connection to the remote host:
# ssh remhost
