-''This document describes how to setup the ax25-utilities package for
-Amateur Radio such that it makes Netrom Nodes for the Node program
-and the BBS software from John-Paul Roubelat, F6FBB. The DOS G8BPQ
-Switch makes a bbs node and many features, it was expected that the
-Linux ax25-utils would have a similar capability. This was not the
-case. Help came from John Ackerman, N8UR who put a message on the
-Linux-Ham SIG that he had done the BBS node and the info was on his
-web site! When the information was tried it didn't work properly but
-much was learned about the technique. Help from Tomi Manninen, OH2BNS
-did the trick. Nodes for the BBS and the Node and the DX Cluster were
-made and work fine.''

-
-!!1. Introduction
-
-
-It is possible, using just the ax25-util's to generate node
-listings for the Node application and the FBB BBS and the DXNet DX
-Cluster. This is done by changing the configuration files for Netrom
-and making a Netrom entry for each application. At present there is a
-kernel imposed limit of 4 Netrom entries. The new kernels are
-expected to drop this limit.
-
-
-Now users look for CRUCES:K5DI-4 and LCBBS:K5DI-3 and
-LCDX:K5DI-5 on the many nodes here in New Mexico, Texas and Arizona
-and are connected like magic. They no longer need to remember
-anything.
-
-
-
-
-
-
-----
-
-!!2. How to Begin
-
-
-Obtain and read the AX25-HOWTO:
-
-
-ftp:/sunsite.unc.edu/pub/Linux/docs/HOWTO/AX25-HOWTO/
-
-
-Using the AX25-HOWTO set up the normal Amateur Radio ax.25
-and Netrom system and make certain it is operating properly. When
-the software "CALL" can be used to make either a ax25 or Netrom
-connection to a distant node, the system is ready to change to one
-using node listings like the BPQ Switch.
-----
-
-!!3. Some Details of the AX.25 Utilities
-
-
-Below is a list of all the applications and files that are
-needed to set up a working ax.25 system. The Applications are all in
-the /usr/sbin/ directory and the Configuration files are in the
-/etc/ax25/ directory. Note: Kissattach is used only if you have TNC's
-in the Kiss Mode.
-
-
-
-
-
-* kissattach Application
-*
-
-* call Application
-*
-
-* ax25d Application
-*
-
-* ax25d.conf Configuration file
-*
-
-* axspawn Application
-*
-
-* axspawn.conf Configuration file
-*
-
-* axports Configuration file
-
-*
-
-
-
-There are several names that a ax25-util user must invent.
-Since this paper uses the files of k5di, a listing of those names can
-be made.
-
-
-
-
-
-Name Call-sign Alias Other
-ax0 k5di-9 ax25 9600 baud
-ax1 k5di-10 ax25 1200 baud
-Netrom k5di-1 #CRUCE Real Netrom
-netnod k5di-4 CRUCES Node node-list
-netbbs k5di-3 LCBBS BBS node-list
-netdx k5di-5 LCDX DX-Cluster
-
-
-It's a good idea to make a list like this on paper before you
-start to change things. It is easy to put the wrong name in a control
-file.
-
-
-Kissattach is an application that connects the kernel
-to the TNC, sets the tcp/ip address up, sets the speed of the
-connection, and is given the serial port to use.
-
-
-Axports is a file that defines the name of the ax.25 ports
-and tells kissattach what call-sign, baud-rate and window size to use.
-Below is an example of a 2 TNC system.
-
-
-
-
-
-# /etc/ax25/axports
-# Be very careful with the speed setting. This is the speed in
-# bits/second that data passes from the computer to the TNC, and has
-# nothing to do with the radio baud rate!
-#
-# The format of this file is:
-#
-# name call-sign speed paclen window description
-#
-ax0 K5DI-9 9600 255 3 445.1 (9600 bps)
-ax1 K5DI-10 9600 255 1 145.07 (1200 bps)
-
-
-
-
-AX25D is the application that reads the ax25d.conf
-Configuration file and answers calls made to the system. Below is a
-sample ax25d.conf that has no Netrom defined. In fact all it will do
-is answer calls to k5di-9 and k5di-10. When it answers it starts the
-node application and logs the caller in.
-
-
-
-
-
-# /etc/ax25/ax25d.conf
-#
-# AX25D Configuration File.
-#
-# AX.25 ports begin with a '
[['.
-#
-[[k5di-4 VIA ax0
]
-default * * * * * 0 - root /usr/sbin/node node
-[[k5di-4 VIA ax1]
-default * * * * * 0 - root /usr/sbin/node node
-#
-
-
-The next step is to get ax25d to answer a call to the alias
-CRUCES as well as the call-sign. This is easy to do and is shown
-below:
-
-
-# /etc/ax25/ax25d.conf
-#
-# AX25D Configuration File.
-#
-# AX.25 ports begin with a '[['.
-#
-[[CRUCES VIA ax0]
-default * * * * * 0 - root /usr/sbin/node node
-[[k5di-4 VIA ax0]
-default * * * * * 0 - root /usr/sbin/node node
-[[CRUCES VIA ax1]
-default * * * * * 0 - root /usr/sbin/node node
-[[k5di-4 VIA ax1]
-default * * * * * 0 - root /usr/sbin/node node
-#
-
-
-
-
-If you have trouble, as root kill ax25d if it is running and
-then at the prompt type ax25d &. As ax25d loads the ax25d.conf file
-it will print out any errors it finds. This print out is very accurate
-and tells you which row in the file is wrong.
-
-
-A connect from any adjacent node to k5di-4 or CRUCES will
-connect to the k5di node. But Netrom is not transmitting a node
-listing for CRUCES or k5di-4. This is done by changing some Netrom
-Configuration files.
-
-
-
-

-
-!!4. Setting Up Netrom
-
-
-Netrom has applications and files that control it's function
-and to achieve the G8BPQ look and function we must use these in ways
-never intended. Below is a list of these components of Netrom:
-
-
-
-
-
-*nrattach Application
-*
-
-*netromd Application
-*
-
-*nrports Configuration File
-*
-
-*nrbroadcast Configuration File
-*
-
-Nrattach is the application that works with the kernel and
-establishes the ports and tcp-ip used by Netrom. To use nrattach you
-place it in your startup file and the example looks like this:
-
-
-
-
-
-/usr/sbin/nrattach -i 44.30.2.5 netrom
-/usr/sbin/nrattach -i 44.30.2.5 netnod
-
-
-
-
-Nrattach gets some of it's information from a configuration file
-called nrports. This file is shown below:
-
-
-
-
-
-# /etc/ax25/nrports
-#
-# The format of this file is:
-#
-# name call-sign alias paclen description
-#
-netrom K5DI-1 #CRUCE 235 Switch
-netnod K5DI-4 CRUCES 235 Real Node
-
-
-
-
-There is no change to the nrbroadcast file so the remaining
-changes will be made to the ax25d.conf file. In this file you
-normally put the real netrom application called k5di-1, but since a
-call to k5di-1 or #CRUCE gets undesirable results, leave that entry
-out of ax25d.conf and a user will get just a "busy" when calling.
-
-
-Instead put in the netnod and that will allow ax25d to answer
-a call to CRUCES. This is shown in the example below:
-
-
-
-
-
-# /etc/ax25/ax25d.conf
-#
-# AX25D Configuration File.
-#
-# AX.25 ports begin with a '[['.
-#
-[[CRUCES VIA ax0]
-default * * * * * 0 - root /usr/sbin/node node
-[[k5di-4 VIA ax0]
-default * * * * * 0 - root /usr/sbin/node node
-[[CRUCES VIA ax1]
-default * * * * * 0 - root /usr/sbin/node node
-[[k5di-4 VIA ax1]
-default * * * * * 0 - root /usr/sbin/node node
-#
-# NET/ROM ports begin with a '<'.
-#
-<netnod>
-default * * * * * * - root /usr/sbin/node node
-#
-
-
-
-
-With these changes netrom node broadcasts will include the
-node K5DI-4:CRUCES and K5DI-1:#CRUCE. By testing it was determined
-that a call from any node to k5di-1 or #CRUCE got a busy, and a call
-to k5di-4 or CRUCES connected to the node on this system.
-
-
-

-
-!!5. Setting Up FBB and DXNet:
-
-
-
-
-
-The FBB packet BBS and DXNet Linux software are written to
-answer calls to a call-sign defined in the configuration files. In
-these examples the FBB call-sign is k5di-3 and the DXNet is k5di-5.
-
-
-Since calls to k5di-3 and k5di-5 are answered by other
-software, ax25d is not used and these calls should NEVER be found in
-a ax25d.conf file. But the nrports file needs to have the information
-added and 2 more nrattach lines are added to the start file. The
-nrattach lines (4 each) and the file "nrports" are shown below:
-
-
-
-
-
-/usr/sbin/nrattach -i 44.30.2.5 netrom
-/usr/sbin/nrattach -i 44.30.2.5 netbbs
-/usr/sbin/nrattach -i 44.30.2.5 netnod
-/usr/sbin/nrattach -i 44.30.2.5 netdx
-# /etc/ax25/nrports
-#
-# The format of this file is:
-#
-# name call-sign alias paclen description
-#
-netrom K5DI-1 #CRUCE 235 Switch
-netnod K5DI-4 CRUCES 235 Real Node
-netbbs K5DI-3 LCBBS 235 FBB BBS
-netdx K5DI-5 LCDX 235 DXNet DX Cluster
-
-
-
-
-These changes will make the node listings wanted but a call
-to LCBBS will not work yet. Recall that FBB answers a call to k5di-3
-but not the alias. To achieve this a change to the
-/usr/local/fbb/system/port.sys file is required. Before these changes
-port.sys had a listing for the name "netrom". With these changes
-replace "netrom" with "netbbs". That section of port.sys is shown
-below:
-
-
-#TNC !NbCh Com !MultCh Pacln Maxfr !NbFwd !MxBloc M/P-Fwd Mode Freq
-0 0 0 0 0 0 0 0 00/01 ---- File-fwd.
-1 8 1 ax0 250 4 1 10 30/60 XUWY UHF port
-2 2 1 ax1 250 4 1 10 00/60 XUWY VHF port
-3 6 1 netbbs 250 4 4 10 30/60 XUWY BPQ look
-4 8 2 0 250 5 4 1000 5/15 TUWY Telnet
-#
-
-
-
-
-A similar change is made to the "dxnet.cfg" file where netrom
-is replaced with netdx. When these changes are made and a few hours
-have passed to let Netrom send node lists, any nearby node will have
-nodes listed to your Netrom for CRUCES and LCBBS and LCDX, and they
-will all work just as they do when using the G8BPQ Switch under DOS
.
