FBB7.0.9 released

Trying BBSURO:N1URO-4… <Enter> aborts.
Virtual circuit established to BBSURO:N1URO-4

There has been quite a bit of activity on the mail list or Fbb in the last 2 weeks. Some bugs have been fixed by Dave, now the Protus C_Filter and the G0LGS M and F Filter are working properly again.

Last release


Brian N1URO has written some installation script for Protus and G0LGS filters and has been working on the translation of the Spanish Protus files.

The appropriate Filters can be downloaded from the links below.




They are currently working on getting rid of some Bugs that cause some errors with Fbb ping and the ReqDir server.

Thanks to Dave, Brian N1URO, Bernard F6BVP, Paul G4APL and Tom SP2L

Great work, Thank you


7.0.8-beta9 (f6bvp, Dave van der Locht)
– [r176] fbblog files renamed from 0 to 52 for week number
fbb log displayed calling executable script /usr/local/bin/fbblog
– [r177] Some functions are done via system() calls. However, observed return value
is invariably -1 while it should reflect the result of called program.
It happened because the SIGCHILD signal handler was set to SIG_IGN.
Fixed at the beginning of the main function in xfbbd.c.

7.0.9 (Dave van der Locht)
– [r178] beta9 was hanging. xfbbd.c patched.
1) Return value of system() is always -1 due to SIGCHLD signal was ignored.
2) Added ‘fail-safe bypass’ in case call_nbdos() couldn’t find the command/executable to run.
3) Replaced system() with popen() in the call_nbdos() function to fix the problem with
response text from a c_filter not coming through.

Systemd and Linfbb

I had some problems starting Linfbb with systemd. The problem turned out to be that Linfbb was running in the background. Systemd was thinking fbb was going offline and kept restarting. Now it is possible to provide start options with fbb.

Command line options of the fbb script :
-f : Software is run in foreground
-h : help information
-q : run silent
-l logfile : log debug info to logfile

Now I put the following in my fbb start file.

The unit file for systemd.

Systemctl status fbb

Now is fbb running just fine.

Xfbb interface with Linbpq

In bpq32.cfg add


This creates a DED Host mode TNC on device /home/pi/fbbded, accessible from the LinBPQ Node as Application 3. Change APPLMASK and APPLICATION line if you already use APPL 3


This allows uses to connect to FBB. You can add the usual Call, Alias and Quality if you want to be able to access FBB directly instead of via the Node.

Change APPLMASK and APPLICATION line if you already use APPL 3

In /usr/local/etc/ax25/fbb/port.sys#

# FBB7.0.8-beta8
#Ports TNCs
1 1
#Com Interface Adress (Hex) Baud
1 9 /home/pi/fbbded 9600
#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 6 1 1 250 2 1 10 00/15 DUWYL 145
# End of file.

This tells fbb to use /home/pi/fbbded as a DED Mode TNC.

Fbb problem showing .HLP and .ENT file

Donnie WD1F has some trouble to get the english.hlp and the english.ent files to show up in fbb. He found the solution.

All the files are there with the right permissions.

I found my problem and it wasn’t easy. In case others have this issue…
The issue was: Pressing H would not give me the help file. After getting it working I see I was missing other things as well like lots of the welcome text.

duckduckgo.com search showed EMSGSIZE (Message too long) had to do with packet sizes allowed. Made me think it may relate to max packet length setting in axports
The fix was:

in /etc/ax25/axports…
name Call speed paclen window desctiption
1 WD1F-1 9600 128 2 144.01 MHz (1200 bps)

I had to set paclen to 255 like this:
1 WD1F-1 9600 255 2 144.01 MHz (1200 bps)

Linfbb maintenance scripts modified.

Brain n1uro has write a script to getting reports sent to you nightly from your maintenance.



I have some trouble to get things going so i change some line in the scipt.

I have change the line


fbbgetconf needs a option.

Output off the script.


Forward from linbpq through uronode to fbb.

There were some problems getting the forward from linbpq through a uronode to a linfbb bbs. I spent a while testing to see if we could get things going. It actually works pretty well.

I have add the following connection script to linbpq

ATT 3 stands for attach port 3, and port 3 is in my system the telnet port.

Furthermore, in uronode.conf I have created an Alias with the name BBS. So if the command BBS is given in uronode, you will be connected with linfbb.

We can test whether the forward script does what it is supposed to do. Let’s start the forward in Linbpq.

Log file of Linbpq

Okay looks good.
