I recently attended Shmoocon 2009, and was surprised to find a few attendees asking me how I got my EVDO Sprint Novatel u727 modem working in BackTrack 3. The process should be the same for BT4, which was just released on Friday at Shmoocon. So for convenience sake, I provide the script I use to connect, and the configuration file for kppp.

evdoconnect.sh:

#!/bin/bash
if [[ $EUID -ne 0 ]]; then
echo "This script must be run as root" 1>&2
exit 1
fi
eject /dev/sr0 2>/dev/null
sleep 1
modprobe -r usbserial
modprobe usbserial vendor=0x1410 product=0x4100
sleep 1
nohup kppp -c "Sprint Wireless" > /dev/null 2> /dev/null &

A note that the vendor and product codes will probably need to be changed if you’re using a different provider or card. Contact your provider for this information.

Again, this is simply my personal configuration. These should work quite the same for other distributions as well, provided that your card is connected via USB.
