NetRom


If you have NetRom nodes as neighbors it is possible to interface your FPAC node with them. The FPAC node will continue to function/look the same. The Linux system will make Netrom Broadcasts and respond to the netrom protocol connects when addressed by it's Netrom Alias:Call-ssid.

To Add the Netrom support to your FPAC node

Load the Netrom Module.

Type :

modprobe netrom
lsmod


Check to see that netrom is in the list of loaded modules. If it has loaded add it to /etc/ax25/ax25-up with the other modprobe lines (near the top).

Edit /etc/ax25/nrbroadcast.

Example

# /etc/ax25/nrbroadcast
#axport Min_Obs DefQ WorstQ Verbose
0 5 195 75 1
9 5 200 100 1


There should be a line entry for each port that you wish to broadcast on.

In the example above ports 0 & 9 are going to broadcast.

Port 9 is AXIP... yes we are sending NetRom broadcasts across the E-Net.

To activate the broadcast to the individual nodes on the AXIP port, you must add a b to the end of the route line in /etc/ax25/ax25ipd.conf.

Example

route k4gbb k4gbb.serveftp udp 10093 b

Edit /add /etc/ax25/nrports.

Example

# Name Call Alias PacLen Description
netrom k4gbb-14 CIT03 236 K4GBB Netrom port


Attach a Netrom port

Add the following line to ax25-up.

/usr/sbin/nrattach -i 44.1.1.3* netrom

* Use <your-Ampernet> address if you have one.

Start netromd

Add another line to ax25-up to start the nrbroadcast daemon.

/usr/sbin/netromd -i -t 30

-i = start broadcast immediately.

-t(n) = time (min) between broadcasts. The default is 30 minutes

Edit ax25d

To have connect request to your NetRom node go to your FPAC switch; add the following lines to /etc/ax25/ax25d.conf

<netrom>
NOCALL * * * * * * L
default * * * * * * - root /usr/sbin/fpacnode fpacnode -q %S
