Your setup now:
Server A: Authenticates User SSL -> runs PHP -> runs su -> runs SSH to
Server B
Server B: Authenticates User SSH -> runs command
My sugggested solution:
Server A: Authenticates User SSL -> runs cURL -> Server B
Server B: Authenticates User SSL -> runs PHP -> runs command
IE:
*MOVE* your PHP script that runs the command to Server B.
Use SSL on both A and B
Use cURL from A to B to authenticate.
B runs PHP which runs command.
You've taken out all the su and SSH stuff between A and B with no real
loss of Security.
You already know how to do everything in my suggested solution, except
maybe cURL, which would take you an hour to figure out, max.
I guarantee you that if you do this, you'll have a lot less headaches, now
and in the future, and a lot cleaner/clearer code-base.
Maybe having the PHP script on Server B is impossible. That's the only
reason *not* to do it this way.
