Calling shell script from PHP is not working as expected?

Make sure that the user that is running the php file (web server user if being called in that context) is set up for password-less authentication as well.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
