Freifunk-Gateway aufsetzen/keyxchangev2 VERALTET

Hier landen die ersten Infos was für Gateways bei KeyxchangeV2 geändert werden muss. Es sind nur Beispieldateien und müssen pro Hood unbedingt angepasst werden! Ungetestet!

Batman

Hab ich leider schon installiert :( Wer es noch vor sich hat bitte hier dokumentieren, hilfreich vermutlich:

[Service]
ExecStart=/usr/bin/fastd -c /etc/fastd/fff.fuerth/fff.fuerth.conf

[Install]
WantedBy=multi-user.target

danach:

systemctl enable fastd
systemctl start fastd

Der Server muss dann händisch in den keyxchangev2 eingetragen werden. Dazu sind folgende Infos nötig:

• IP Adresse (aktuell v4)
• Port von fastd
• Servername
• Hood
