RouterWars is a wifi mod to leave SSID messages via wireless network SSID within it's range.

RouterWars utilizes custom firmware based on OpenWrt, a Linux OS which targets embedded devices. All messages are publicly accessible to anyone within the routers range, i.e. so instead of seeing 'NETGEAR' in the menu of available networks from your devices, you might see 'Watch out for the Cop on 4th and Perry'. The SSID once selected automatically opens and reroutes any request to its GUI.

Each ID is a field string that can be edited through a web interface portal which is accessible when you click on the open SSIDs being broadcast. When connecting to any of the SSIDs the access point sets up a captive portal to reroute any web page requests to the web interface. It can be used to leave anonymous messages to people within its range, warnings to activists or protesters in the area or even to troll your neighbors.

• buy a TP-Link WiFi Router (reference https://openwrt.org/toh/hwdata/tp-link/start for supported models)
• flash firmware
• setup ssh and login password (sexylama)
• run setup.sh
  • chmod +x setup.sh
  • ./setup.sh
• restart access point
• connect to "Free Public WifiTagger"
• open any url -> web interface should open

• plugin router to ethernet (not wan port)
• open web interface at http://192.168.0.1/ or http://192.168.1.1/
  • user: admin
  • password: admin
• restore factory settings if anythings was changed
• run system upgrade uploading the firmware with the "factory" suffix
  • openwrt-ar71xx-generic-tl-wr741nd-v4-squashfs-factory.bin
• do not interrupt upload

• after restart you can now telnet to router "telnet 192.168.1.1" and
• set a password with "passwd"
• then telnet gets disabled and ssh login works with "ssh [email protected]"
• also "ssh -o UserKnownHostsFile=/dev/null [email protected]" if you have key problems

• this will copy a bunch of files to the router
• amoung them setup_remote.sh
• which it will then also execute

• if something doesn't work ssh to router and
• run setup_remote.sh manually
• check output for errors

Use dnsmsqr to wildcard all domains to the routers IP. In "/etc/dnsmasq.conf" add "address=/#/192.168.1.1" and restart dnsmasq. The "#" could also be a "com" to reroute all .com domains.
