Dropbear Public-Key authentication

Public-Key authentication allows you to log in to your routers console without needing to type your password. Instead a public-key will be used to authenticate you.

 Easy

• OpenSSH
• PuTTY
• Key authentication

1. install ssh-client on your clients (OpenSSH, Putty)
2. prepare private-/public-key's (ssh-keygen, Puttygen)

Dropbear automatically looks in '/etc/dropbear/authorized_keys' for known identities. All needs to be done is to append the own public-key to this file.

In the following example i simply cat my public key into a new 'authorized_keys'-file and copie it onto the router.

• New something

cat .ssh/id_dsa.pub > authorized_keys
scp authorized_keys 192.168.1.1:/etc/dropbear/

After that, logging in from a mashine with my public-key won't require a password:

:~ $ ssh 192.168.1.1
