Babel und dnsmasq in unsere firmware

Diese Seite befindet sich noch im Entwurfsstadium.
Hilf mit sie zu verbessern!

Um aus einem Router ein Gateway zu machen, muss in die Firmware Olsr und dnsmasq mit eingebaut werden. Dieses Patch baut diese 2 Programme plain mit ein, es müssen danach noch diverse Konfigurationen und Routingparameter gesetzt werden. Es kann sich dazu ganz grob an die Anleitung zum Gateway aufsetzen gehalten werden.

Achtung! Man sollte sich bei solchen Experiementen immer gut überlegen wie man den Router noch erreichen kann, man kann sich relativ leicht selbst komplett aussperren. Nach diesem Patch baut der Router z.b. kein fastd Batman mehr zu einem Gateway auf, er mesht aber noch frei mit anderen Routern und spannt auch noch ein WLAN auf.

Zu beachten gilt auch, das dnsmasq und Olsr zu groß für 4MB Router sind, die Firmware wird nicht für jeden Router bauen. Ich hab sie aktuell für ar71xx gebaut und auf einen wr1043 (hat 8MB Flash) verwendet.

2.1.4

Ich hab dies mal grundsätzlich in einem neuen Git getan: [1] Das ganze ist noch ungetestet!

Folgendes muss grundsätzlich danach noch getan werden damit er als Gateway verwendet werden kann:

Verbindung ins L3 Netz

Irgendeine Art von Verbindung in unser L3 Netz. Ich habe dazu fastd im tun Modus verwendet um ein Gateway über das Internet zu erreichen, natürlich sind auch Glasfaser, WLAN, Laser, Morsecode o.ä. Verbindungen denkbar.

Server:

bind any:1234; # UDP Port 1234 auf allen Interfaces
mode tun;
interface "fffolsrVPN";
method "null";
mtu 1426;
secret "SECRET KEY DES SERVERS";

#include peers from "peers";
include peer "/etc/fastd/fff.olsr/peers/router1";
on up "
  ip link set up $INTERFACE
  ip address add 10.50.252.****/32 dev $INTERFACE # eigene Tunnelip setzen
";

fff-gw-cd1 /etc/fastd/fff.olsr/peers # cat router1
key "PUBLIC KEY DES ROUTERS";

Client:

 
log to syslog level warn;
method "null";
mode tun;
interface "fffgwcd1VPN";
mtu 1426;
peer "fffgwcd1" {
  remote ipv4 "SERVERIP" port 1234;
  key "SERVER PUBLIC KEY";
}
secret "EIGENER SECRET KEY";
on up "
#/etc/fastd/fff/up.sh
";
secure handshakes no;

irgendwo muss hier noch eine IP gesetzt werden für den Tunnel, bin mir eben nicht sicher wie ich das getan habe:

ip link set up fffgwcd1VPN
ip address add 10.50.252.*** dev fffgwcd1VPN

Ebenfalls muss fastd noch in den Autostart, ich glaub ich hab dazu einen Cron gebastelt, damit falls der Link abbricht wieder neu aufgebaut wird. Muss u.U. noch schöner gemacht werden ;)

2 wertvolle Links die bei fastd extrem weiterhelfen: [2] [3]

Folgende Routingregeln müssen am Router angelegt werden

Auf dem Router muss ebenfalls die 10 fff angelegt werden:

vi /etc/iproute2/rt_tables

...
10     fff
...

Weiterhin müssen folgende Regeln angelegt werden (z.b. in der /etc/rc.local):

ip rule add from 10.0.0.0/8 table fff prio 20
ip rule add to 10.0.0.0/8 table fff prio 20
ip route add 10.50.XXX.XXX/XX dev br-mesh table fff # eigenes Subnetz das später per DHCP vergeben wird

Das Interface br-mesh muss noch die Gateway IP bekommen:

/etc/config/network

...
config interface 'mesh'
        option type 'bridge'
        option auto '1'
        option macaddr '30:b5:c2:0e:c9:54'
        list ip6addr 'fdff:0::30b5:c20e:c954/64'
        list ip6addr 'fdff:0::1/64'
        list ip6addr 'fdff:0::32b5:c2ff:fe0e:c954/64'
        option ipaddr '10.50.130.1'
        option netmask '255.255.254.0'
        option proto 'static'
        option ifname 'eth0.1 bat0'
...

ToDo: IPv6 muss auch angepasst werden!

Olsr konfigurieren

Olsr muss am Router konfiguriert werden, dazu wird im /etc/olsrd/olsrd.conf eine Konfigurationsdatei erwartet die Beispielhaft so aussehen kann. Zwingend angepasst werden muss das/die Interface(s) und die HNA.

#
# olsr.org OLSR daemon config file
#
# Lines starting with a # are discarded
#
# This file was shipped with the debian olsrd package
#

# Debug level(0-9)
# If set to 0 the daemon runs in the background

DebugLevel 0	

# the interface the mesh runs on is specified at run time using the -i flag

Interface "fffgwcd1VPN"
{
  # Olsrd can autodetect changes in NIC configurations (IP address
  # changes etc.).  This is enabled by default and the interval to
  # poll for changes on is defined by NicChgsPollInt.  This polling
  # can be disabled pr. NIC by setting AutoDetectChanges to no.

  #AutoDetectChanges            no

  # IPv4 broadcast address to use. The
  # one usefull example would be 255.255.255.255
  # If not defined the broadcastaddress
  # every card is configured with is used

  Ip4Broadcast		255.255.255.255

  # IPv6 address scope to use.
  # Must be 'site-local' or 'global'

  #Ip6AddrType		site-local

  # IPv6 multicast address to use when
  # using site-local addresses.
  # If not defined, ff05::15 is used

  #Ip6MulticastSite		ff05::11

  # IPv6 multicast address to use when
  # using global addresses
  # If not defined, ff0e::1 is used

  #Ip6MulticastGlobal	ff0e::1


  # Emission intervals.
  # If not defined, RFC proposed values will
  # be used in most cases.

  # Hello interval in seconds(float)
    HelloInterval		6.0

  # HELLO validity time
    HelloValidityTime		600.0

  # TC interval in seconds(float)
    TcInterval			0.5

  # TC validity time
    TcValidityTime		300.0

  # MID interval in seconds(float)
    MidInterval			10.0

  # MID validity time
    MidValidityTime		300.0

  # HNA interval in seconds(float)
    HnaInterval			10.0

  # HNA validity time
    HnaValidityTime		300.0

  # When multiple links exist between hosts
  # the weight of interface is used to determine
  # the link to use. Normally the weight is
  # automatically calculated by olsrd based
  # on the characteristics of the interface,
  # but here you can specify a fixed value.
  # Olsrd will choose links with the lowest value.

  #Weight 0


  # If a certain route should be preferred 
  # or ignored by the mesh, the Link Quality 
  # value of a node can be multiplied with a factor 
  # entered here. In the example the route 
  # using 192.168.0.1 would rather be ignored.
  # A multiplier of 0.5 will result in a small
  # (bad) LinkQuality value and a high (bad)
  # ETX value.

#NatThreshold  0.7

#LinkQualityMult 10.50.252.251 1.0 
#LinkQualityMult 10.50.252.10 0.7

  # LinkQualityMult default 0.8

Olsr muss noch in den Autostart gekickt werden, ich hab dazu in die rc.local einfach olsrd eingetragen, dann startet Olsr bei Routerstart mit.

Wünschenswert wäre es gleich noch ein Routingprotokoll mit aufzunehmen das auch IPv6 gleichzeitig kann, aktuell tendiert der allgemeine Trend zu babel

dnsmasq konfigurieren

ebenfalls muss noch dnsmasq konfiguriert werden:

/etc/dnsmasq.conf

dhcp-range=10.50.131.1,10.50.131.127,255.255.254.0,1h                            
dhcp-option=3,10.50.130.1
dhcp-option=option:dnsserver,10.50.252.250                                                             
log-queries  

natürlich die IP Adressen entsprechend anpassen der Syntax lautet:

dhcp-range=DHCP_RANGE_START,DHCP_RANGE_ENDE,SUBNETZMASK,LEASETIME
dhcp-option=3,STANDARTGATEWAYIP
dhcp-option=option:dnsserver,DNSSERVER
log-queries  

muss noch auf Vollständigkeit geprüft werden!

Alfred

Leider ist noch kein Alfredproxy für die Router geschrieben worden, aktuell umgehe ich das Problem indem ich die Alfreddaten mit einen zusätzlichen Raspberry Pi sammel und ans Monitoring schicke, Infos dazu hier [4]

WLAN Parameter

Ebenfalls müssen die WLAN Parameter angepasst werden, wenn eine eigene Hood entsteht sollten mindestens folgende Parameter geändert werden:

Mesh:

• BSSID
• SSID

AP:

• SSID

Die eigene Hood kann aber auch mit ganz anderen Parametern betrieben werden, so ist z.b. denkbar die Hood auf 802.11s umzustellen oder gar eine andere Batmanversion zu verwenden.
