There must be something useful here…

I found the holy grail for any network admin, password-less login. This gives you the power to run remote scripts, forget passwords, and control the world… well maybe. Anyways, lets get to it. This specific post is talking about how to remotely login to an AirOS system (Ubiquiti). I’ll assume you are using a Linux system, or if not, you will need to know how to generate your own rsa key.

First, open an ssh session to the radio in question and do the following:

#vi /tmp/system.cfg

Next add users.1.homedir=/etc/persistent and type the following:


#cfgmtd -w -p /etc/
#reboot


Next do ssh-keygen to generate a new RSA key. You will be asked for a directory and a passphrase. Make sure you leave passphrase blank, or you will have to enter that key each time.

Now you will need to make a directory and copy the public key to the AirOS system:

#ssh username@x.x.x.x 'mkdir /etc/persistent/.ssh/'
#cat ~/.ssh/id_rsa.pub | ssh username@x.x.x.x 'cat >> /etc/persistent/.ssh/authorized_keys'


If you changed the directory during the ssh-keygen process, make the change in the command above.

Now make your changes persistent with this command:
#cfgmtd -w -p /etc/

You should be able to login without a password!
