Generating and uploading SSH keys under Windows
This FAQ describes how to manually generate and configure SSH keys using Windows. First create a new user from the Opengear Management Console on Opengear gateway (the following example users a user called "testuser") making sure it is a member of the "users" group. If you do not already have a public/private key pair you can generate them now using ssh-keygen, PuTTYgen or a similar tool:
- PuTTYgen:
- OpenSSH:
- OpenSSH (Windows):
- For a good overview of SSH key generation:
For example using PuTTYgen first make sure you have a recent version of the puttygen.exe and make sure you have a recent version of WinSCP (available from ). To generate a SSH key using PuTTYgen :
- Execute the PUTTYGEN.EXE program
- Select the desired key type SSH2 DSA (you may use RSA or DSA) within the Parameters section ... and it is important that you leave the passphrase field blank
- Click on the Generate button
- 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
- 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
