# Conigure a "spare router" in a known-good state.
|
||||
|
||||
# This script configures the factory default settings of OpenWrt
|
||||
# to make it easy to swap it in when a new router is needed.
|
||||
# It also displays important configuration information when complete.
|
||||
# You can print out those lines and tape them to the router so
|
||||
# the next person will know how to access the router in the future.
|
||||
# The format is:
|
||||
#
|
||||
# Configured: YYYY-MMM-DD
|
||||
# Device: Belkin RT3200
|
||||
# OpenWrt: 22.03.5 r20134-5f15225c1e
|
||||
# LAN: 192.168.253.1
|
||||
# User: root
|
||||
# Login PW: SpareRouter
|
||||
# WiFi SSID: SpareRouter
|
||||
# WiFi PW: none
|
||||
|
||||
# The default settings of the script are generic, but the router will work.
|
||||
# You could make a copy of this script, customize it to your needs,
|
||||
# then use the "To run this script" procedure (below).
|
||||
#
|
||||
# ***** To run this script *****
|
||||
#
|
||||
# Flash the router with factory firmware. Then SSH in and execute these statements.
|
||||
# You should do this over a wired connection because some of these changes
|
||||
# can reset the wireless network.
|
||||
#
|
||||
# ssh root@192.168.1.1
|
||||
# cd /tmp
|
||||
# cat > config.sh
|
||||
# [paste in the contents of this file, then hit ^D]
|
||||
# sh config.sh
|

# Presto! (You should reboot the router when this completes.)
