Dies ist eine stark verkürzte Anleitung wie man Mesh auf seinen Server bekommt. Wichtig: die IPs anpassen!

Software

Tunneldigger

cd /opt/
git clone https://github.com/wlanslovenija/tunneldigger.git
cd tunneldigger/client/

cmake .
make

Respondd

cd /opt/
git clone https://github.com/ffggrz/ext-respondd.git
cd ext-respondd/
cp alias.json.example alias.json
cp config.json.example config.json

alias.json anpassen!

/opt/ext-respondd/config.json:
