One of the first things you will probably want to do when setting up a new Vyatta / vRouter / VyOS install, is to enable SSH so you can configure it from your desk.
The secure shell (SSH) service allows you to securely administer the device from a remote location on the network.
These steps below outline how to enable SSH.
Enter configuration mode
Enable the SSH service
# set service ssh
Commit the changes
Save the configuration
Exit configuration mode
vyatta@vyatta:~$ configure  vyatta@vyatta# set service ssh  vyatta@vyatta# commit [ service ssh ] Restarting OpenBSD Secure Shell server: sshd.  vyatta@vyatta# save Saving configuration to '/config/config.boot'... Done  vyatta@vyatta# exit exit vyatta@vyatta:~$
You should now be able to SSH into your Vyatta / vRouter / VyOS device.
