CMG-DCM Data Communications Module
The routes are specified as arguments to the standard Unix route
command. For example, if you wanted the DCM to route traffic to and
from IP addresses beginning 192.168.0. over the eth0 interface, you
would include the line
add -net 192.168.0.0 netmask 255.255.255.0 dev eth0
in the list.
For more information on the route command, please see its Linux
manual page.
6.7 DNS setup
The settings on the Configuration – DNS setup refer to the Domain
Name Service (DNS) used by the DCM, which translates numeric IP
addresses into names.
It is not essential that you set up DNS for the DCM to work, or to
update the software.
net.dns.domain : The name of the domain containing the module. For
example, a DCM at
myinst.bignet.org would have its domain set to
bignet.org.
The rest of the settings on this page determine how the DCM
determines the addresses of other hosts on the network from their host
names.
