Console Server & RIM Gateway User Manual
- Follow the instruction to move the mouse over the blank area of the program in order to create random data used by
PUTTYGEN to generate secure keys. Key generation will occur once PUTTYGEN has collected sufficient random
data
- 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 Opengear gateway 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 Opengear
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.
15.6.6 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 .
