rip98d - Send and receive RIP98 routing messages
SYNOPSIS
rip98d [-d] [-l] [-r] [-t interval] [-v]
DESCRIPTION
The RIP98 routing protocol was devised by John Wiseman G8BPQ as an alternative to both traditional RIP and RSPF for use in an RF environ-
ment. Its main advantage is that each routing element only takes six bytes and is therefore much more efficient in terms of bandwidth than
other routing protocols.
In operation rip98d that each neighbour that also uses RIP98 must be listed. RIP98 is not a broadcast protocol and each neighbour is indi-
vidually contacted. Any incoming RIP98 message is also validated against this list. The list of neighbours is held in
/etc/ax25/rip98d.conf, and each line is either the name or the dotted decimal IP address of the neighbour.
The time interval between RIP98 transmissions is set to one hour by default but other intervals can be set with the -t option. The routes
advertised and received can be restricted by the -r option which only allows processing of ampr.org addresses. At present rip98d is under
development and any feedback on its operation would be welcome.
OPTIONS -d Set debugging on. Information is only output if the logging option is also enabled.
-l Enable logging to the system log, the default is off.
-r Restricts the transmitting and receiving of routes to ampr.org (44.x.x.x) addresses only.
-t interval The time interval between routing broadcasts, in minutes. The default is 60 minutes.
-v Display the version.

netromd - Send and receive NET/ROM routing messages
SYNOPSIS
netromd [-c] [-d] [-i] [-l] [-p pause] [-q quality] [-t interval] [-v]
DESCRIPTION
For a NET/ROM based network to operate correctly, a periodic broadcast of routing information needs to occur. Typically this occurs once
every hour on every port which is expected to carry NET/ROM traffic. The purpose of netromd is to send and receive NET/ROM routing broad-
casts. To operate correctly a set of parameters that corresponds to each AX.25 port needs to be passed to the program. This information is
encoded in a configuration file, by default which is /etc/ax25/nrbroadcast with each line representing one port, see the manual page for
nrbroadcast(5).
To cut down the length of these routing broadcasts, only the information about the highest quality neighbour for a particular node is
transmitted. The transmission is also limited to those node that have a certain minimum value in their obsolesence count, this value is
decremented every time a routing broadcast is transmitted, and is refreshed by receiving a routing broadcast which contains that particular
node.
The value of the default quality is traditionally assigned a value that represents the quality of the radio links on that port. A higher
number representing better radio links with 255 (the maximum) reserved for wire connections. The practise in the UK is to set the default
quality to a low value, typically 10, and manually set up the trusted neighbouring nodes in the neighbour list manually. The worst quality
for auto-updates value is a way to filter out low quality (ie distant) nodes.
The verbose flag may be either 0 or 1, representing no and yes. By specifying no, the program will only generate a routing message contain-
ing information about the node on which it is running, by specifying the yes option, all the information in the nodes routing tables will
be transmitted. The quality advertised for the other node callsigns on this machine may be set using the -q option.
Between each transmission netromd pauses for five seconds (default) in order to avoid flooding the channels that it must broadcast on. The
value of this delay is settable with the -p option.
OPTIONS -c Forces strict compliance to Software 2000 specifications. At present this only determines how node mnemonics with lower
case characters will be handled. With compliance enabled mixed case node mnemonics will be ignored. The default is to
accept node mnemonics of mixed case.
-d Switches on debugging messages, the default is off. Logging must be enabled for them to be output.
-i Transmit a routing broadcast immediately, the default is to wait for the time interval to elapse before transmitting the
first routing broadcast.
-l Enables logging of errors and debug messages to the system log. The default is off.
-p pause Sets the delay between transmissions of individual routing broadcast packets. The default is five seconds.
-q quality Sets the quality of the subsidiary nodes relative to the main node. The default is 255.
-t interval The time interval between routing broadcasts, in minutes. The default is 60 minutes.
-v Display the version.
