Revision as of 02:10, 21 April 2007
Dieser Node besteht momentan aus einem Soekris 4501 Board und soll die Verbindung zwischen den einzelnen Funkwolken in Hamburg und Freifunk Initiativen in anderen Staedten herstellen. Als VPN Software wird Tinc-VPN eingesetzt, wobei allerdings in Zukunft vermutlich auch andere VPN Protokolle unterstuetzt werden koennen.
Interfaces
Hier eine kurze Uebersicht ueber die verschiedenen Netzwerk-Interfaces.
eth0
Das eth0 Interface ist momentan noch ungenutzt.
Interface Name: eth0 IP Adresse : none Hostname : none Description : not used yet Bandwidth : 0bit
eth1
Das eth1 Interface ist zwar up, wird aber in der Regel ebenfalls nicht genutzt.
Interface Name: eth1 IP adresse : 193.158.228.140 Hostname : none Description : secondary uplink Bandwidth : 1500kbit/s
eth2
Ueber das eth2 Interface wird momentan die ganze VPN Geschichte abgewickelt. Es ist moeglich per SSH sich einzuloggen, sofern man den dafuer noetigen Account, oder Exploit hat. Das Tinc-VPN lauscht hier auf den Ports 655 und 656.
Interface Name: eth2 IP adresse : 62.206.27.20 Hostname : vpn1.hamburg.freifunk.net Description : primary uplink Bandwidth : 4000kbit/s
ffhh
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. Der OLSR Daemon sendet seine Pakete an die Broadcast-Adresse (10.127.255.255) ueber dieses Interface.
Interface Name: ffhh IP Adresse : 10.112.1.1/12 Hostname : none Description : Freifunk Hamburg Software : tinc-vpn, olsrd Tinc-Port : 656
ffvpn
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: ffvpn IP Adresse : 10.207.0.9/16 Hostname : hamburg-r1.hamburg.freifunk.net Description : tunnel staedtekopplung Software : tinc-vpn, quagga(bgpd) Tinc-Port : 655 AS-Number : 65044
