SSH console (PuTTY) with DHCP/TFTP output
DnsMasq Configuration File (/etc/dnsmasq.conf)
The following configuration example needs to be adapted to your network and RFPs.
Change all lines with “192.168.112.” to match your LAN. Use a calculator (e.g. Windows
“Calc”) to convert the hex values in the “openmob,43” line: 192=0xc0, 168=0xa8, 112=0x70,
and 52=0x34. Also change the MAC address (here: 00:30:42:0d:10:2e) to the value printed
on the backside label of the RFP that is designated as OMM.
# Disable DNS service for this dnsmasq instance
port = 0
# The OMM (specific MAC used) needs a fixed IP
dhcp-host = 00:30:42:0d:10:2e,net:openmob,192.168.112.52
# Set net:openmob for clients that send Vendor=='OpenMobility'
dhcp-vendorclass=openmob,OpenMobility
# Ignore queries that does not send Vendor=='OpenMobility'
dhcp-ignore=#openmob
# Set the firmware file name for bootp requests
dhcp-boot = net:openmob,omm_ffsip.tftp
# Specify options to be send to all RFPs
dhcp-option = openmob,224,"OpenMobility" # Let RFP accept our config
dhcp-option = openmob,43,0a:04:c0:a8:70:34 # Hex: 192.168.112.52 is OMM
dhcp-option = openmob,option:router,192.168.112.1
dhcp-option = openmob,option:dns-server,192.168.112.1
dhcp-option = openmob,option:domain-name,"mycompany.de"
dhcp-option = openmob,option:ntp-server,0.0.0.0
# The 'dhcp-range' is required otherwise DNSmask does not serve DHCP
dhcp-range = net:openmob,192.168.112.52,192.168.112.55,,,1h
# This dnsmasq also acts as TFTP server
enable-tftp
tftp-root=/var/lib/tftpboot
The “dhcp-range” statement may overwrite the default netmask and broadcast settings.
Adapt “,,,1h”, e.g. to “255.255.255.0,192.168.112.255,1h” for this.
OMM selection
One RFP of a set needs to function as OpenMobility Manager (OMM). The configuration
suggested above will select a specific RFP for this role with the “DHCP option 43”. The OMM
is generally selected
