How to setup

• create user in your system using the command provided below

  useradd xrambad --shell=/bin/true

  this will make the user have no shell + sftp and scp access.

• create ssh key for the user.

• there will be issue that user can't login to fix this add /bin/true to /etc/shells

• start your minecraft server with the plugin installed. but you will notice that it will not load the plugins as shown down below.

  [09:16:17 WARN]: [AppleTunneler] no Identities files found, please put them in plugins/AppleTunneler/Identities
  [09:16:17 ERROR]: Error occurred while enabling AppleTunneler v1.0-SNAPSHOT (Is it up to date?)
  

• place your user that you created private key into plugins/AppleTunneler/Identities folder

• start server again, but you will be met with another error as shown below

    [09:20:16 ERROR]: [AppleTunneler] FILE at path: /home/test/Desktop/test-server/plugins/AppleTunneler/.known_hosts Does not exists
    [09:20:16 ERROR]: Error occurred while enabling AppleTunneler v1.0-SNAPSHOT (Is it up to date?)
    java.lang.RuntimeException: Known host file does not exists in plugin folder
  

  as you can see the error created path for us which will be easy for us to create the file, now copy the path.

• run this command to create the host file ssh-keyscan limework.net >> /home/test/Desktop/test-server/plugins/AppleTunneler/.known_hosts

• now modify the config of the plugins for your needs by setting host, port, username of ssh server and setting tunneling needed.

and done.
