DESCRIPTION
This program is used to manipulate the routing tables of the NET/ROM
network layer, or to get and set many of the network and transport
layer parameters for the NET/ROM protocol. The program has three basic
modes of operation, node setting, neighbour setting and general parame‐
ter setting. The syntax for the node and neighbour setting is taken
from the original NET/ROM manual and is therefore not very UNIXy but
should be familiar to those familiar with NET/ROMs or TheNet.
To set up a new route to a NET/ROM node in the routing tables you must
use the nodes option. All of the parameters are needed to add the node.
It is probably best to illustrate with an example:
nrparms -nodes GB7BPQ + NMCLUS 120 6 vhf G8ROU-3
This creates a new route to a distant node with the callsign GB7BPQ and
the alias NMCLUS, it has a quality of 120 (out of 255) and has an obso‐
lescence count of six and packets for that node should be sent on the
AX.25 port named vhf to my immediate neighbour G8ROU-3. The callsigns
of the node and the neighbour may be the same. For example to set up
the node G8ROU-3 which is also my immediate neighbour, I would use:
nrparms -nodes G8ROU-3 + MATLCK 200 6 vhf G8ROU-3
If the ident of the remote node is not known, it is possible to add a
node with a blank ident. To do this an ident of ’*’ must be entered on
the command line. Because of the command line expansion that shells do,
the * must be escaped by enclosing it in quotes.
It is also possible to remove a route to a distant node with the same
command except that the + is replaced by a -. The other parameters must
also be present. If the node has not other routes then the node will be
deleted, and the neighbour node that the connections go via may also be
deleted if no other node route uses it, and it is not a locked neigh‐
bour entry.
When setting up a new node, a new neighbour entry may also be created.
This will have a default value. For that neighbour to be meaningful in
the automatic routing process, it must have a more reasonable entry in
the neighbours list. To do this the routes option of the command must
be used. An example:
nrparms -routes ax0 G8ROU-3 + 120
This will create (or update) the neighbour entry for G8ROU-3 with a
quality of 120 and it will be locked, it will not create a node entry
for the neighbour. This quality will be used by the netromd(8) program
when calculating route qualities via this neighbour. Normally once a
neighbour has zero node routes going via it, it will be deleted. Lock‐
ing a neighbour prevents the deletion from occurring. To unlock a
neighbour entry, the same command is used but with the + replaced by a
-.
