17 This program is used to manipulate the routing tables of the NET/ROM
18 network layer, or to get and set many of the network and transport
19 layer parameters for the NET/ROM protocol. The program has three basic
20 modes of operation, node setting, neighbour setting and general parame‐
21 ter setting. The syntax for the node and neighbour setting is taken
22 from the original NET/ROM manual and is therefore not very UNIXy but
23 should be familiar to those familiar with NET/ROMs or TheNet.
24 To set up a new route to a NET/ROM node in the routing tables you must
26 use the nodes option. All of the parameters are needed to add the node.
27 It is probably best to illustrate with an example:
28 nrparms -nodes GB7BPQ + NMCLUS 120 6 vhf G8ROU-3
30 This creates a new route to a distant node with the callsign GB7BPQ and
32 the alias NMCLUS, it has a quality of 120 (out of 255) and has an obso‐
33 lescence count of six and packets for that node should be sent on the
34 AX.25 port named vhf to my immediate neighbour G8ROU-3. The callsigns
35 of the node and the neighbour may be the same. For example to set up
36 the node G8ROU-3 which is also my immediate neighbour, I would use:
37 nrparms -nodes G8ROU-3 + MATLCK 200 6 vhf G8ROU-3
39 If the ident of the remote node is not known, it is possible to add a
41 node with a blank ident. To do this an ident of '*' must be entered on
42 the command line. Because of the command line expansion that shells do,
43 the * must be escaped by enclosing it in quotes.
44 It is also possible to remove a route to a distant node with the same
46 command except that the + is replaced by a -. The other parameters must
47 also be present. If the node has not other routes then the node will be
48 deleted, and the neighbour node that the connections go via may also be
49 deleted if no other node route uses it, and it is not a locked neigh‐
50 bour entry.
51 When setting up a new node, a new neighbour entry may also be created.
53 This will have a default value. For that neighbour to be meaningful in
54 the automatic routing process, it must have a more reasonable entry in
55 the neighbours list. To do this the routes option of the command must
56 be used. An example:
57 nrparms -routes ax0 G8ROU-3 + 120
59 This will create (or update) the neighbour entry for G8ROU-3 with a
61 quality of 120 and it will be locked, it will not create a node entry
62 for the neighbour. This quality will be used by the netromd(8) program
63 when calculating route qualities via this neighbour. Normally once a
64 neighbour has zero node routes going via it, it will be deleted. Lock‐
65 ing a neighbour prevents the deletion from occurring. To unlock a
66 neighbour entry, the same command is used but with the + replaced by a
67 -.
