ListAsLAN is a plugin that sends a mutlicast signal to all listening Minecraft clients on your local area network. This allows your spigot or bukkit server to automatically be listed in the server selection screen.

This plugin only works for clients on your local area network.
The intented use is for friends and family who want to play on a local spigot/bukkit server.

How it works:
Every five seconds this plugin sends an asynchronous broadcast to the 224.0.2.60:4445 mutlicast address. This is the local address that Minecraft clients listen to for LAN games.
The contents of the multicast message is as follows:

Code (Text):

[MOTD]YOUR SEVER MOTD[/MOTD][AD]YOUR SERVER PORT[/AD]

Issues to note:

• Custom MOTDs that are set by plugins are ignored. Only the MOTD in the 'server.properties' file is used.
• Servers with a complex MOTD message may not display as intended. There doesn't appear to be a work around for this at the moment, aside from simplifying the message or just putting up with it.

Troubleshooting:
If your server does not appear on the server list, try these:

• Make sure you're conntected to the same network as the server (via. Ethernet or Wifi)
• Check if your Minecraft client's mutlicast scan is being blocked by your firewall (I find this happens a lot with Minecraft's LAN)
• Check if the server's multicast signal is being blocked by the firewall.
