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/

Tinc Connections


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:

config 'supernode' 'vpn1'
	 option 'port' '4204'

config 'edge' 'ffhh'
	 option 'mac' '00:11:22:33:44:55'
