Some Details of the AX.25 Utilities</A></H2> <P>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. <P> <UL> <LI> kissattach Application</LI> <LI> call Application</LI> <LI> ax25d Application</LI> <LI> ax25d.conf Configuration file </LI> <LI> axspawn Application</LI> <LI> axspawn.conf Configuration file</LI> <LI> axports Configuration file </LI> </UL> <P>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. <P> <BLOCKQUOTE><CODE> <PRE> 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 </PRE> </CODE></BLOCKQUOTE> 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. <P>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. <P>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. <P> <BLOCKQUOTE><CODE> <PRE> # /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) </PRE> </CODE></BLOCKQUOTE> <P>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. <P> <BLOCKQUOTE><CODE> <PRE> # /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 # </PRE> </CODE></BLOCKQUOTE> 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: <BLOCKQUOTE><CODE> <PRE> # /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 # </PRE> </CODE></BLOCKQUOTE> <P>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. <P>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. <P> <P> <HR> <A HREF="Netrom-Node-4.html">Next</A> <A HREF="Netrom-Node-2.html">Previous</A> <A HREF="Netrom-Node.html#toc3">Contents</A> </BODY> </HTML>
