How to manage password with exec('scp...

[nemonoman]

I'd like to issue an scp command to copy some remote files from one server to another on a regular cron basis.

scp runs very fast from my console, but how do I put it into a PHP script when it asks for a password??

[root@35235 test]# scp -r [e-mail]:www/1 test
[e-mail]'s password:

I could say exec('scp -r [e-mail]:www/1 test').

How do then manage the password challenge via PHP?

What you need to do is make the server you are copying data to trust the server/user that data is coming from. This is done by passing around the proper keys. Here is a basic write up on how to do it http://www.linuxhorizon.ro/ssh-wo-passw.html .
