[TriLUG] ssh question

[Brian via TriLUG]

PPK ++.

I use this to great convenience with almost all of my ssh hosts around 
my network.  Seems like it would be a good fit for your situation, since 
it (in a sense) transfers the authentication to the client machine 
rather than the client user (machine's private key vs. user's password 
knowledge), and you've only got one client machine (the "another Pi") to 
worry about.

Run ssh-keygen on "another Pi", specify an empty password, and put the 
public key in the presenting Pi's /home/pi/.ssh/authorized_keys file. 
Then set the client Pi's .ssh/config to automatically use the PPK pair 
to log in.  Example config on the client:

Host presenterpi
	IdentifyFile ~/.ssh/id_rsa

(using the default file name)

Cheers,
-Brian
