ppp

(sorry for my bad english)

I want run ppp connection when my usb modem is connect. so i use next udev rule:

ACTION=="add", SUBSYSTEM=="tty", ATTRS{idVendor}=="16d8",\
RUN+="/usr/local/bin/newPPP.sh $env{DEVNAME}"

(my modem appear in /dev as ttyACM0)

newPPP.sh:

#!/bin/bash
/usr/bin/pon prov $1 >/dev/null 2>&1 &

Problem:

udev event fire, newPPP.sh running, BUT newPPP.sh process will be killed after ~4-5s.
ppp not have time to connect. (in it params is timeout 10s for dial up).

How can i run long time process, that will not be killed?

(I was try nohup. It don't work too.)
