Fping problem

Hi All, I have written a simple page that uses fping and was working perfectly just shelling out to it using the backtick. The server it was on crapped out and I'm trying to get it going again on our new server. I have installed fping, given permissions to everyone to run it and copied it to the places where it was before. /usr/local/bin /bin /sbin And it will not return the input I give it. Anybody in the house got an ideas? Idiot me didn't document what I did to get it going in the first place... Thanks Matthew
