Subject: [gentoo-user]  Copying a file via ssh with no password, keeping the system safe
Date: Thu, 07 Oct 2010 18:45:49 +0200	[thread overview]
Message-ID: <20101007184549.65756vlexbx2u7sw@momessonet.ath.cx> (raw)


Hi list,

I need to set up a cron job to transfer a file every day from server A  
to server B.

I'd like to do that via ssh and with no user assistance, completely automated.

Setting up a public key, would do the job, but then, all the  
connections between the servers would be passwordless, so if server A  
gets compromised, also server B is screwed.

Is there a way to allow only one single command from a single cronjob  
to operate passwordless, while keeping all the other connections  
secured by a password?

Thank you in advance for your help.
