3. Setting up the AX25 Utilities

-

3.1 Allowing ax25 connects from users +

The aim of this section is not to fully cover the installation +and configuration of all the possible ax25 modules. I will +attempt to cover a simple installation and configure 2 serial +ports as if they had TNC's on them. I will also show what +additional configuration the DXSpider program requires.

+ +

Please bear in mind that I am basing this section on a RedHat +7.1 distribution, if you are using SuSe or any other distibution +then your mileage may vary. I will be happy to make any changes +and additions if you email me any errors or distribution specific +requirements.

+ +

You would probably benefit from reading the +AX25-HOWTO which is much more +comprehensive and an interesting configuration program is also available +called +ax25-config which +may help you to configure things.

+ +

The following files are extracts from the working files at GB7MBC and +are in daily use. However, there are many ways that you can configure the +ax25 utils, this is just the one I use, it does not mean it is necessarily +the best or for that matter, the right way!

+ +

3.1 Getting Started

-

As stated previously, the aim of this document is not to tell you how to -configure Linux or the ax25 utilities. However, you do need to add a line -in your ax25d.conf to allow connections to DXSpider for your users. For -each interface that you wish to allow connections on, use the following format ... -

-

-
-default  * * * * * *  - sysop /spider/src/client client %u ax25
-
-
-

or, if you wish your users to be able to use SSID's on their callsigns .. +

There are 2 things you need to do initially. You need to get the +3 files required for the ax25 installation and you need to make +some changes to the kernel configuration.

+ +

The first thing is to get the versions of the ax25 utils that match +your kernel. You may also wish to get a node package of some kind. +There are 2 main node packages in use of which I shall keep to the +original by Tomi Manninen, OH2BNS as this is included in the ax25 +rpms as standard. The other is +AWZNode by IZ5AWZ.

+ +

NB: The AX25 stuff in 2.4 kernels appears to have been broken until 2.4.18. I +strongly suggest you get at least this kernel.

+ +

For 2.4 kernels you need these files...

+

-

-
-default  * * * * * *  - sysop /spider/src/client client %s ax25
-
-
-

For most purposes this is not desirable. The only time you probably will -need this is when you need to allow other cluster nodes that are using SSID's -in. In this case it would probably be better to use the first example and -then add a specific line for that node like this: +

+

+ +

3.2 The kernel +

+ +

First you need to add Amateur Radio Support to your kernel. This is +a main menu item and should be easily found. Within this header you +will find lots of options. For our purposes you need to enable +Amateur Radio AX.25 Level 2 Protocol, NET/ROM and the Serial Port +KISS Driver. For the purposes of this document I will work under the +assumption that you include them in the kernel fully, ie not as modules. +If you need to look at compiling your kernel for ax25 more fully, I would +refer to the excellent +AX25-HOWTO

+ +

I should say at this stage that NET/ROM is not mandatory. If you do not use it +simply ignore any instruction concerning it.

+ +

Now recompile your kernel in the normal way and reboot your system.

+ +

3.3 Installing the RPM's +

+ +

Now install the RPM's you downloaded, libax25 first, then ax25-tools, +then ax25-apps.

-GB7DJK-2  * * * * * *  - sysop /spider/src/client client gb7djk-2 ax25
-default  * * * * * *  - sysop /spider/src/client client %u ax25
+rpm -ivh libax25-0.0.7-7.i386.rpm
+rpm -ivh ax25-tool-0.0.6-13.i386.rpm
+rpm -ivh ax25-apps-0.0.4-9.i386.rpm
 
-

-

3.2 Allowing telnet connects from users +

+ +

3.4 Configuration

-

-From version 1.47 there is a new (more efficient) way of doing this -(see next section) but, if you prefer, the method of doing it described -here will continue to work just fine. -

-

Allowing telnet connections is quite simple. Firstly you need to add a line -in /etc/services to allow connections to a port number, like this .... +

You will find the configuration files in /etc/ax25. These consist of +several files ...

-

-
-spdlogin   8000/tcp     # spider anonymous login port
-
-
-

Then add a line in /etc/inetd.conf like this .... +

+

+ +

These are the main files. You will find other files but they do not +have any use unless you are wanting to use that particular protocol, +Rose or axip for example.

+ +

NOTE:- before we start it is important to realise that every interface +requires a different SSID. You should be able to follow this in the +following examples.

+ +

3.5 axports +

+ +

This file sets up the ax25 ports you want to use. An example is below +for a standard TNC2 ...

-spdlogin stream tcp nowait root /usr/sbin/tcpd /spider/src/client login telnet
+#portname   callsign   baudrate   paclen   window   description
+ 2m         gb7mbc-2   19200      256      2        2m port on 144.900MHz
+ 4m         gb7mbc-4   19200      256      2        4m port on 70.325MHz
 
+

+ +

Note that the portnames have to be unique.

+ +

The file headings are as follows ...

-

Once this is done, you need to restart inetd like this .... -

-

-killall -HUP inetd
+portname        -       The name you will refer to the port by
+callsign        -       The ax25 callsign you want to assign to the port
+baudrate        -       The speed you communicate between TNC and computer
+paclen          -       The maximum packet length for ax25 connections
+window          -       The ax25 window parameter.  This is like 'maxframe'
+description     -       A textual description of the port
 
-
-

-

-

Now login as sysop and cd spider/src. You can test that spider -is accepting telnet logins by issuing the following command .... +

+ +

3.6 nrports +

+ +

This file sets up the netrom ports you want to use. An example is below +and includes a port for both cluster and node. You will see why we need +2 ports later ...

-./client login telnet
+#portname   callsign   alias   paclen   description
+ netrom     gb7mbc-8   BARE    236      Node Netrom Port
+ netrom2    gb7mbc-9   MBCDX   236      Cluster Netrom Port
 
-

You should get a login prompt and on issuing a callsign, you will be given -access to the cluster. Note, you will not get a password login. There seems -no good reason for a password prompt to be given so it is not asked for. -

-

Assuming all is well, then try a telnet from your linux console .... +

+ +

Note that the portnames have to be unique.

+ +

The file headings are as follows ...

-

-telnet localhost 8000
+portname        -       The name you will refer to the port by
+callsign        -       This is the callsign that NET/ROM traffic from this
+                        port will use
+alias           -       The NET/ROM alias this port will be assigned
+paclen          -       The maximum size of NET/ROM frames transmitted
+description     -       A textual description of the port
 
-
-

-

You should now get the login prompt and be able to login as before. -

-

3.3 Setting up telnet connects (from 1.47 onwards) +

+ +

3.7 nrbroadcast

-

From version 1.47 you can choose to allow the perl cluster.pl program to -allow connections directly (i.e. not via the /spider/src/client -interface program). If you are using Windows then this is the only method -available of allowing incoming telnet connections. -

-

To do this you need first to remove any line that you may previously have set -up in /etc/inetd.conf. Remember to:- +

This file sets up the netrom broadcast qualities. An example is below ...

-killall -HUP inetd
+#axport   min_obs   def_qual   worst_qual   verbose
+ 4m       5         10         100          1
 
+

+ +

The file headings are as follows ...

-

to make the change happen... -

-

Having done that, you need to copy the file -/spider/perl/Listeners.pm to /spider/local and -then edit it. You will need to uncomment the line containing "0.0.0.0" -and select the correct port to listen on. So that it looks like this:- -

-

-
-@listen = (
-    ["0.0.0.0", 8000],
-);
-
-
-

-

As standard, the listener will listen on all interfaces simultaneously. -If you require more control than this, you can specify each interface -individually:- -

-

-@listen = (
-    ["gb7baa.dxcluster.net", 8000],
-    ["44.131.16.2", 6300],
-);
+axport          -       The port name in axports that you wish to broadcast
+                        NET/ROM on.
+min_obs         -       The minimum obsolescence value for the port
+def_qual        -       The default quality for the port
+worst_qual      -       The worst quality for the port.  Any routes under
+                        this quality will be ignored
+verbose         -       This flag determines whether you will only broadcast
+                        your own node (0) or all known nodes (1)
 
-
-

-

This will only be successful if the IP addresses on each interface are static. -If you are using some kind of dynamic IP addressing then the 'default' method -is the only one that will work. -

-

Restart the cluster.pl program to enable the listener. -

-

One important difference with the internal listener is that no echoing -is done by the cluster program. Users will need to set 'local-echo' on in -their telnet clients if it isn't set automatically (as per the standards). -Needless to say this will probably only apply to Windows users. -

-

3.4 Setting up for AGW Engine (1.47 onwards) -

+

-

AGW Engine is a Windows based ax25 stack. You can connect to an AGW engine -from Linux as well as Windows based machines. -

-

In order to enable access to an AGW Engine you need to copy -/spider/perl/AGWConnect.pm to /spider/local and edit it. -Specifically you must:- -

-

- -

-

-

3.5 Setting up node connects +

3.8 ax25d.conf

-

In order to allow cluster node connections, spider needs to know that the -connecting callsign is a cluster node. This is the case whether the connect -is incoming or outgoing. In spider this is a simple task and can be done in -runtime. -

-

Later versions of Spider can distinguish different software and treat them -differently. For example, the WCY beacon cannot be handles by AK1A type -nodes as AK1A does not know what to do with PC73. There are 4 different -types of node at present and although they may not have any major -differences at the moment, it allows for compatibility. The 4 types are ... +

This file controls any incoming ax25 and NET/ROM connections and steers +them to the relevant program. There are lots of configuration options +you can set here, however they are well covered in the AX25-HOWTO. For +our purposes I will show a typical set of parameters. An example is +below ...

-set/node        (AK1A type)
-set/spider
-set/dxnet
-set/clx
-
-
-

-

For now, we will assume that the cluster we are going to connect to is an -AK1A type node. -

-

Start up the cluster as you did before and login as the sysop with client. -The cluster node I am wanting to make a connection to is GB7BAA but you would -obviously use whatever callsign you required. At the prompt type ... -

-

-
-set/node gb7baa
+[gb7mbc-0 via 2m]
+parameters    2 1   6  900 *  15  0
+NOCALL *  *  *  *  *  *  L
+default  * * * * * *  - sysop /spider/src/client client %u ax25
+
+[gb7mbc-1 via 2m]
+parameters    2 1   6  900 *  15  0
+NOCALL *  *  *  *  *  *  L
+default *  *  *  *  *  *  0  root  /usr/sbin/node  node
+
+[gb7mbc-0 via 4m]
+parameters    2 1   6  900 *  15  0
+NOCALL *  *  *  *  *  *  L
+default  * * * * * *  - sysop /spider/src/client client %u ax25
+
+[gb7mbc-1 via 4m]
+parameters    2 1   6  900 *  15  0
+NOCALL *  *  *  *  *  *  L
+default *  *  *  *  *  *  0  root /usr/sbin/node  node
+
+<netrom2>
+parameters 1    10 * * * 3 *
+NOCALL *  *  *  *  *  *  L
+default  * * * * * *  - sysop /spider/src/client client %u ax25
+
+<netrom>
+parameters 1    10 * * * 3 *
+NOCALL *  *  *  *  *  *  L
+default *  *  *  *  *  *  0  root  /usr/sbin/node  node
 
-

-

The case does not matter as long as you have a version of DXSpider later than -1.33. Earlier versions required the callsign to be in upper case. -

-

That is now set, it is as simple as that. To prove it, login on yet another -console as sysop, cd to spider/src and issue the command ... +

+ +

There are a few things to take note of here. Firstly, all ax25 +sections are wrapped in [ ] and all NET/ROM sections are wrapped in +< >. Secondly you should be able to see that anyone who forgets to +set their callsign in a TNC and tries to connect with the standard +NOCALL set into their TNC will not connect, the 'L' means 'lockout'. +Lastly and importantly, notice the order of the sections. They are +all done in interface order.

+ +

You should be able to see that the normal line for access to the +cluster is like this ..

-./client gb7baa (using the callsign you set as a node)
+default  * * * * * *  - sysop /spider/src/client client %u ax25
 
-

-

You should get an initialisation string from DXSpider like this ... +

+ +

however, if you wish your users to be able to use SSID's on their callsigns ..

-./client gb7baa
-PC38^GB7MBC^~
+default  * * * * * *  - sysop /spider/src/client client %s ax25
 
-

If the callsign you just set up as a cluster node is for an incoming connect, -this is all that needs to be done. If the connection is to be outgoing then -a connection script needs to be written. -

-

Sometimes you make a mistake... Honest, it does happen. If you want to make a node -back to being a normal user, regardless -of what type it is, do: +

+ +

For most purposes this is not desirable. The only time you probably will +need this is when you need to allow other cluster nodes that are using SSID's +in. In this case it would probably be better to use the first example and +then add a specific line for that node like this:

-unset/node gb7baa
+GB7DJK-2  * * * * * *  - sysop /spider/src/client client gb7djk-2 ax25
+default  * * * * * *  - sysop /spider/src/client client %u ax25
 
-

-

3.6 Connection scripts +

+ +

3.9 node.conf

-

Because DXSpider operates under Linux, connections can be made using just about -any protocol; AX25, NETRom, tcp/ip, ROSE etc are all possible examples. -Connect scripts live in the /spider/connect directory and are simple ascii files. -Writing a script for connections is therefore relatively simple. -

-

The connect scripts consist of lines which start with the following keywords -or symbols:- -

-

-

-

#

All lines starting with a # are ignored, as are completely -blank lines. -

-

timeout

timeout followed by a number is the number of seconds to wait for a -command to complete. If there is no timeout specified in the script -then the default is 60 seconds. -

-

abort

abort is a regular expression containing one or more strings to look -for to abort a connection. This is a perl regular expression and is -executed ignoring case. -

-

connect

connect followed by ax25, agw (for Windows users) or telnet and some type dependent -information. In the case of a telnet connection, there can be up to -two parameters. -The first is the ip address or hostname of the computer you wish to -connect to and the second is the port number you want to use (this -can be left out if it is a normal telnet session). -In the case of an ax25 session then this would normally be a call to -ax25_call or netrom_call as in the example above. It is your -responsibility to get your node and other ax25 parameters to work -before going down this route! -

-

'

' is the delimiting character for a word or phrase of an expect/send -line in a chat type script. The words/phrases normally come in pairs, -either can be empty. Each line reads input from the connection until -it sees the string (or perl regular expression) contained in the -left hand string. If the left hand string is empty then it doesn't -read or wait for anything. The comparison is done ignoring case. -When the left hand string has found what it is looking for (if it is) -then the right hand string is sent to the connection. -This process is repeated for every line of chat script. -

-

client

client starts the connection, put the arguments you would want here -if you were starting the client program manually. You only need this -if the script has a different name to the callsign you are trying to -connect to (i.e. you have a script called other which actually -connects to GB7DJK-1 [instead of a script called gb7djk-1]). -

-

-

There are many possible ways to configure the script but here are three examples, -one for a NETRom/AX25 connect, one for AGW engines and one for tcp/ip. +

For those of you that wish to run the node, you need to set up the +node.conf file. There are a couple of additional files, node.perms is +very similar to the way ftp permissions are set up in NOS systems and +node.motd is the message anyone logging into the node will get. +The node.conf file sets all the parameters of the node as you would +expect. An example is below ...

-timeout 60
-abort (Busy|Sorry|Fail)
-# don't forget to chmod 4775 netrom_call!
-connect ax25 /usr/sbin/netrom_call bbs gb7djk g1tlh

+

+ +

This should be fairly obvious I hope.

+ +

3.10 Getting it all running +

+ +

Ok, now we have all the relevant files configured, the next step is to get +it all running.

+ +

The first thing to do is attach the TNC's. Your TNC's should be in KISS mode +and connected to the serial ports involved.

+ +

You now use the 'kissattach' command to connect the TNC's to the system like this ...

-timeout 60
-abort (Busy|Sorry|Fail)
-# this does exactly the same as the previous example
-# the '1' is the AGW port number to connect thru for g1tlh
-connect agw 1 g1tlh
-'Connect' '' 
-'Connect' 'c np7'
-'Connect' 'c gb7dxm'
-# you can leave this out if you call the script 'gb7dxm'
-client gb7dxm ax25
+kissattach /dev/ttyS0 2m 44.131.96.199
+kissattach /dev/ttyS1 4m 44.131.96.199
 
-

-

+

+ +

Assuming that 44.131.96.199 is your IP address. The devices ttyS0 and ttyS1 are com1 and +com2 respectively. Now we can set some parameters ...

-timeout 15
-connect telnet dirkl.tobit.co.uk
-'login' 'gb7djk'
-'word' 'gb7djk'
-# tell GB7DJK-1 that it is connected to GB7DJK
-# you can leave this out if you call this script 'gb7djk'
-client gb7djk telnet
+kissparms -p 2m -t 150 -l 150 -s 50 -r 50
+kissparms -p 4m -t 150 -l 150 -s 50 -r 50
 
-

-

Both these examples assume that everything is set up properly at the other end. -You will find other examples in the /spider/examples directory. -

-

3.7 Starting the connection -

+

-

You start the connection, from within a sysop enabled cluster login, by typing -in the word connect followed by a script name like this .... +

The command 'man kissparms' will give you the explanation of the switches.

+ +

Now we need to attach the NET/ROM ports in the same way ...

This will start a connection using the script called gb7djk-1. You can -follow the connection by watching the term or console from where you started -cluster.pl. From version 1.47 onwards, you will need to set/debug connect first. -You should see something like this ... +

+ +

All of the above can be put in a file and called from /etc/rc.d/rc.local. Put all +the above commands in a file called rc.ax25 and put a line in rc.local to call it.

+ +

Now you can start the daemons that set everything in motion ...

With later versions of Spider there is a set/login command for users. This -tells them when a user or node logs in or out. If you do not add a line to -your scripts after the final line (or before the client line which should always -be last if needed) then the login/logout information will be sent to users -before the login actually completes. This means if a node is -unreachable, it will continue sending logins and logouts to users even though it -is not actually connecting. To avoid this use the following line ... +

+ +

All should now be running. All that remains is to get the node working for telnet +connections. If nothing else, this will allow you to connect to the node yourself +to check on connection status etc. There are 2 files that need to be edited.

+ +

First edit /etc/services and add

-'connect' ''
+node    3000/tcp     #OH2BNS's Node Software
 
-

-

In a script, this might look like ... +

+ +

Assuming you want it to run on port 3000

+ +

Now cd /etc/xinetd.d and edit a new file called node. It should look like this ...

-timeout 35 
-abort (Busy|Sorry|Fail)
-connect telnet mary 3000
-'ogin:' 'gb7mbc'
-'>' 'telnet 44.131.93.96 7305'
-'connect' ''
+# default: on
+#       unencrypted username/password pairs for authentication.
+service node
+{
+        socket_type     = stream        
+        wait            = no
+        user            = root
+        server          = /usr/sbin/node
+        log_on_failure  += USERID
+        disable         = no
+}

3.8 Telnet echo -

+

-

Cluster links in particular suffer greatly from the presence of telnet echo. -This is caused by the telnet negotiation itself and can create at worst severe -loops. At best it creates unnecessary bandwidth and large logfiles! There are -things that can be done to limit this problem but will not always work dependent -on the route taken to connect. -

-

Telnet echo itself should only be a problem if the connection is being made to -the telnet port (23). This port uses special rules that include echo negotiation. -If the connection is to a different port, such as 7300, this negotiation does -not happen and therefore no echo should be present. -

-

Sometimes it is not possible to make a direct connection to another node and this -can cause problems. There is a way of trying to suppress the telnet echo but -this will not always work, unfortunately it is difficult to be more specific. -Here is an example of what I mean ... +

You now need to restart the xinetd daemon. First find out what the PID is +like so ..

-timeout 35
-abort (Busy|Sorry|Fail)
-connect telnet mary.lancs.ac.uk
-'ogin:' 'gb7mbc'
-'word:' 'mypasswd'
-'\$' 'stty -echo raw'
-'\$' 'telnet 44.131.93.96'
-'connect' ''
+ps auxw |grep xinetd
 
-

So, the first connection is made by Spider. This is fine as Spider uses the -Net_Telnet script from within perl. This actually uses TCP rather than TELNET -so no negotiation will be done on the first connection. Once connected to -mary.lancs.ac.uk, the command is sent to suppress echo. Now a telnet is made -to a cluster node that is accepting connections on port 23. The problem with -this link is that the negotiation is made by the remote machine, therefore you -have no control over it. The chances are that this link will create echo and -there will be no way you can stop it. -

3.9 Autostarting the cluster -

+

-

Ok, you should now have DXSpider running nicely and allowing connects by cluster -nodes or users. However, it has to be shutdown and restarted manually. It -would be much easier to have it start automatically. -

-

This is not only a way to start the cluster automatically, it also works as a -watchdog, checking the sanity of DXSpider and respawning it should it crash for -any reason. Before doing the following, shutdown the cluster as you did earlier. -

-

Login as root and bring up the /etc/inittab file in your favourite editor. Add -the following lines to the file near the end ... +

You will get a reply something like this ...

-##Start DXSpider on bootup and respawn it should it crash
-DX:3:respawn:/bin/su -c "/usr/bin/perl -w /spider/perl/cluster.pl" sysop >/dev/tty7
+root       592  0.0  0.1  2256  620 ?        S    Feb07   0:00 xinetd -stayalive -reuse -pidfile /var/run/xinetd.pid
 
-

-

This line works fine for RedHat distributions. It is also fine for SuSE up to -7.0. From Suse 7.1 you need to add runlevels 2 and 5 like this ... +

+ +

The PID or Process ID is 592 in this case so now we can issue the command ...

-DX:235:respawn:/bin/su -c "/usr/bin/perl -w /spider/perl/cluster.pl" sysop >/dev/tty7
+kill -HUP 592
 
-

-

The line required for Slackware distributions is slightly different. My thanks to -Aurelio, PA3EZL for this information. +

+ +

All should now be operational and you should be able to log into the node by +using a telnet session to the relevant port, like so ...

-DX:23:respawn:/bin/su - sysop -c "/usr/bin/perl -w /spider/perl/cluster.pl" >/dev/tty7
+telnet localhost 3000
 
-

-

This will automatically start DXSpider on tty7 (ALT-F7) on bootup and restart -it should it crash for any reason. -

-

As root type the command telinit q. DXSpider should start up -immediately. You will see the output on tty7 and if you login as sysop -you should find everything running nicely. -

+

+ +

If that works, you are just about there. you should (assuming you have radios connected +to the TNC's) be able to connect out to other stations and receive incoming ax25 and +netrom connections.
