Freifunk:VPN1
Der Inhalt dieser Seite ist veraltet. Wenn du etwas neues hinzufügen kannst, sei mutig!
Dieser Node besteht momentan aus einer virtuellen Maschine unter VMware ESXi und soll die Verbindung zwischen den einzelnen Funkwolken in Hamburg und Freifunk Initiativen in anderen Staedten herstellen. Als VPN Software wird Tinc-VPN, OpenVPN und n2n eingesetzt. Eine kleine Hilfestellung fuer die VPN Konfiguration auf Basis von OpenWRT kann man hier finden: Freifunk:IP:VPN_Connect
Es gibt ein Looking Glass im Hamburger Freifunk Netz, das allerdings auch nur aus dem Freifunk Netz erreichbar ist: http://lg.hamburg.freifunk.net/

Interfaces
Hier eine kurze Uebersicht ueber die verschiedenen Netzwerk-Interfaces.
eth0
Das eth0 Interface ist momentan noch ungenutzt.
Interface Name: eth0 IP Adresse : 62.206.43.20 Hostname : vpn1.hamburg.freifunk.net Description : uplink Bandwidth : 10mbit up/down
ffhh_tinc
Dieses Interface ist fuer das Hamburger Freifunk Netz eingerichtet. Tinc-VPN setzt dieses Interface in den TAP-Modus, damit Pakete zwischen den einzelnen VPN Clients wie bei einem Switch verschickt werden koennen. Die OLSR und B.A.T.M.A.N. Daemons senden ihre Pakete an die Broadcast-Adresse (10.127.255.255) ueber dieses Interface.
Interface Name: ffhh_tinc IP Adresse : 10.112.1.1/12 Hostname : none Description : Freifunk Hamburg Software : tinc-vpn, olsrd Tinc-Port : 656
ffhh_ovpn
Interface Name: ffhh_ovpn IP Adresse : 10.112.1.3/12 Hostname : none Description : Freifunk Hamburg Software : openvpn, olsrd OpenVPN-Port : 4223
ffhh_n2n
Interface Name: ffhh_tinc IP Adresse : 10.112.1.4/12 Hostname : none Description : Freifunk Hamburg Software : n2n, olsrd
icvpn
Fuer das InterCity-VPN wurde dieses Interface eingerichtet. Tinc-VPN setzt auch dieses Interface in den TAP-Modus und die Quagga Routing Suite kuendigt den Hamburger Freifunk IP-Bereich an entfernte BGP-Router. Wir verwenden die interne AS-Nummer 65044 fuer das BGP-Peering.
Interface Name: icvpn IP Adresse : 10.207.0.9/16 Hostname : none Description : tunnel staedtekopplung Software : tinc-vpn, quagga(bgpd) Tinc-Port : 655 AS-Number : 65044

n2n
Auf diesem Knotenpunkt laeuft ein n2n-supernode, an den sich n2n Clients anbinden koennen.
Hostname : vpn1.hamburg.freifunk.net Port : 4201 Community : ffhh Password : ffhh
Der Supernode Daemon wird ueber inittab respawnt, wenn der Prozess stirbt. Aus der /etc/inittab:
7:23:respawn:/usr/bin/supernode -l 4201 -v &> /var/log/n2n-supernode.log
l2gvpn
Auf diesem Knotenpunkt laeuft ebenfalls ein l2gvpn Supernode und der dazugehoerige Client.
Hostname : vpn1.hamburg.freifunk.net Port : 4204 Community : ffhh Password : ffhh
Sowohl Supernode, als auch Client werden ueber die /etc/inittab gestartet und respawnet, wenn der Prozess stirbt. Aus der /etc/inittab:
8:23:respawn:/usr/local/sbin/l2gvpn-supernode vpn1 &> /var/log/l2gvpn-supernode.log 9:23:respawn:/usr/local/sbin/l2gvpn-node ffhh &> /var/log/l2gvpn-node.log
Die dazugehoerige uci Konfiguration aus /etc/config/l2gvpn sieht wie folgt aus:
