FBB Packet-radio BBS mini-HOWTO by Miroslav "Misko" Skoric YT7MPB

Linux FPAC mini-HOWTO by Bernard Pidoux F6BVP
FPAC LINUX MINI HOWTO describes how to install and set up the FBB BBS on
a packet radio network taking advantage of level 3 automatic routing
using ROSE protocol and FPAC nodes (an F6FBB application too).
This is probably the most convenient packet routing system available for
hamradio through Internet and radio links

Raspberry Pi
A lot of Radio Amateurs around the world are using the Respberry Pi as their computer.

To Run
Linux networking applications and supporting services on the amprnet.

Below is a link to F6BVP Bernard's web site and his current work.
At least give you a good staring point.

He has prepared an image containing the required networking
applications that just need configuring

Another Radio Amateur Charley K4GBB has done some good work

G4APL has used
a selection of this information from both these Radio Amateur's to create his experimental
APpLe and Raspberry Pi
(256MB Memory) node APLRPI back in 2012
and with the Raspberry Pi (1GB Memory) version 2  and 3 Model B nodes APLPIE 2016

Use Mozilla's Thunderbird to access your FBB SP Mail and Bulletins
You can now use Thunderbird(mail/news) to connect to the GB7CIP LinFBB 7.0.8 server via the Internet or amprnet.
GB7CIP now has a user using a Mobile Phone (AndroidOS) using K-9 Mail to read and send
(SP AX25 Mail) mail.

The firewalls have now been configured so you can use the pop3(6110)/smtp(6025)
 to read
and send your
  SP(email) to and from the GB7CIP LinFBB server.
  also AX25 Bulletins (nntp newgroups)

Address the SP mail address as you would do. i.e.
when using a standard AX25 Client. CALLSIGN@BBSCALL.#Area.COUNTRY.CONTINENT
You can also use Reply to messages and bulletins received.

For a bulletins, again address as you would do as when using an AX25 Client. e.g.

Remember your LinFBB SysOp needs to enable Telnet access on your LinFBB User account.
YOU! need to disable paging if you have it enabled.  Using the OP command.

All message
s need to be plain text by default

To configure SMTP and POP3

TNC2PPP eprom info for TNC2+WIN95/98  (3Kbytes)  enter TNC2PPP at bbs prompt(g4apl has this working on win98pc driving a BSX2 TNC)

The simplest version to get going if you have a TNC2 clone
(e.g. Tiny2, TNC200, BSX2)  or Baycom, in JNOS running under DOS or a DOS window. 
Though we only have experience of using TNC2's.

  You can always do your own thing afterwards, once you have got going and gained some experience.
a) TCPIP Over AX25
Paul found that he could set-up this system up and working in 30 minutes using an Ethernet Virtual Driver and an Ax25inet interface to drive a TNC2 in KISS mode. Allowing all the windows IP enable programs to access the local TCPIP GB7CIP server over 1200bd or 9600bd radio Interfaces 
TCPIP over AX25 document
(Links referred to in this document are no longer active)

Using your windows system soundcard to generate the tones and  drive your transceiver. (or AGW drive the TNC in KISS mode)

c) Windows
Setup your Win3.11, win95/98,2000,XP PC to route via the jnos PC over the  Ethernet connection between the jnos and windows machines.



Reported to work well on TCP/IP using windows sound card. Win98, ME, 2000, XP.
g4apl has had no experience of this software.  Other than spoken to a station nr Bristol via the amprnet ip network who is very please with the system.  MixW Web Site
e) URONode
URONode is a friendly User frontend that sits ontop of the Linux ax25 tools, utils, apps and IP networking software which gb7cip uses on a very busy hard disk based system, instead of LinuxNode(which had security issues).
It supports cross-port digipeating, automatic routing, various IP functions, and ANSI colours.
There is also a Raspberry Pi image distribution that take ten minutes to configure and
get up and running. Once the image is on a SD memory card and plugged into the
RaspberryPi. Note G4APL only Uses AX25 NetRom TCPIP (not FLexnet or ROSE) for the UK Network.

f) Xrouter
Use Paula's (g8pzt) XROUTER on a scrap Dos PC connected to your Windows PC over the Ethernet.  (Quite easy to setup once you have read the manual, PC min specification 386 640KB ram, small hard disk,  serial ports, TNC, Ethernet card)  or run XROUTER on it's own.  Then use the standard Windows supplied internet programs  IWeb Browser e.g. via radio web server Telnet, FTP, Outlook or Outlook Express for pop3(mail) and nntp (Bulletins) network games over TCP/IP etc. and any other program that uses TCP/IP

These are the notes extracted from the article written by G4HIP.
A little screed on getting an NNTP server working with NOS. While intended for those using TNOS developed by Brian Lantz, it may be of help to other NOS users as well."
Can be article found on the attached link G4HIP NNTP for VIRGINS

h) Microsoft Outlook Express

i) NNTP EMAIL Dialog
Another Email, NNTP Newsreader that you may like to experiment with is Dialog from  40tude Web site.
We have run it under Windows XPpro and Win 98 successfully sending and receiving Email and News Articles from gb7cip.  It is very configurable and could replace Outlook.
j) MAILGW Modified by G4HIP assisting Paul  G4APL to fix major bugs back in 1998/1999.  Is a Linux suite of applications used with INN and SENDMAIL at GB7CIP. Now working with INN 2.5.3 and current version of  Sendmail 17.5.2014l 
Here are the latest map files based on the gateway.txt file. 
It is assumed that you have a fully working MAILGW AX25<>TCPIP gateway using the following files.

MAILGW 0.3.1 G4HIP Patches. refer to G4HIP Web site

k) Jnos example of the resulting config file
Jnos commands Manual (1994) in pdf format
e.g. GB7CP                                         enter SMTPFIX at bbs prompt)

m) JNOS program function Keys   
1)     The version that the Caterham SysOps suggest you use is a self installing package called  (1.39Mbytes)Available from  Internet   (preferred)
Old no longer supported- noted here for history.

2)   YAPP from gb7cip  directory  yapp/tcpip/nosins2k.zipNote: The XFBB Server here does it's housekeeping at 02:00 hours and restarts
3)   7PLUS   connect to GB7CIP(CIPBBS)  then issue the command  7pserv yapp/tcpip/
 this will send you 70+ files of 15 Kilobytes each.

  You will need to identify your local TCP/IP server and frequency that you will use to access your local hub(Server) and the rest of the TCP/IP network

You are most welcome to use if you can access one of our frequencies direct. (makes our life easier as we can assist in helping you getting it going if you use the suggested software and a TNC). 

Connect to gb7cip-5 and enter info and ports for details.
Once you have the software and keen to get up and running, you will require an amprnet TCP/IP address to be allocated to you. Information required (please send to g4apl)
Did you previously hold, currently hold another callsign.
Please advise all the UK callsigns you have held.
    e.g. Foundation, Intermediate, A/B, A, B Licence. QTH   (TCP/IP addresses are issued based on where you live)
     (as explained in UK IP ADDRESSING SCHEME) Local TCP/IP HUB and frequency that you plan to use for your local access point of presence (POP) to the network.
(Just like you use your Internet ISP for access)
