# create_tap_device.sh

|
#
|
||
|
|
# This script sets up an XBee network interface (xbnet) in tap mode. It creates a virtual Ethernet interface
|
||
|
|
# that runs over the XBee radio network, assigns it an IP address, and brings the interface up.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# ./create_tap_device.sh --index=<int> --subnet=<value> --port=<device> --serial-speed=<baudrate>
|
||
|
|
#
|
||
|
|
# Examples:
|
||
|
|
# ./create_tap_device.sh --index=1 --subnet=10.10.10 --port=/dev/ttyUSB0 --serial-speed=230400
|
||
|
|
# - Creates a tap interface with IP 10.10.10.1 using /dev/ttyUSB0 at 230400 baudrate.
|
||
|
|
#
|
||
|
|
# ./create_tap_device.sh --index=2 --subnet=192.168.2 --port=/dev/ttyUSB1 --serial-speed=115200
|
||
|
|
# - Creates a tap interface with IP 192.168.2.2 using /dev/ttyUSB1 at 115200 baudrate.
