dnroute is a daemon that manages the DECnet routing tables to provide a simple
but probably useful routing policy.
dnroute listens for incoming routing messages and adds routes in the kernel for non-local areas that it
sees. Routes will be modifed according to these messages so that the lowest cost route that is up will
always be used. Routes to locally accessible nodes (it those in the neighbour table) will also be added.
If you want to keep manual control of the route to a particular area, then add a line into dnroute.conf.
eg:
manual 26
will disable dnroute's setting of routing tables for that area. dnetinfo will still show the route that
would have been set with (M) on the line to show it has been overidden.
To implement its routing policies dnroute assumes that all interfaces on the system have a cost of 4. To
change this add lines in /etc/dnroute.conf for each of the interfaces you need to change. eg
eth0 6
eth1 8
tap0 10
A script called dnetinfo is provided that gets the routing information from dnroute and displays it on
stdout in a format similar to the VMS command SHOW NET/OLD.
