fping gets return packet when run from terminal, a script, but not when the script is called by transmission-daemon

I'm using the following .. fping -c1 computer I get 0% packet loss when I run it manually from the terminal. I get 0% packet loss when I run it from a script, ~/scripts/torrent.done.script. But I get 100% packet loss when transmission-daemon triggers, and runs the script. computer : xmt/rcv/%loss = 1/0/100% I'm at a loss trying to figure this out. I tried specifying the IP address explicitly, I tried using only IPv4 but same results. I tried with a public IP address, same results. It tried with a VPN and without, same results. ping works, fping does not. So bizarre, to me.
