Watchdog

I use watchdog to monitor my RPI. Do services go offline or the RPI is not responding, watchdog kicks in and restart the system. Now I also want watchdog to watch my Linbpq. This is possible with watchdog, watchdog looks at a PID file. As far as I know, no PID file is created when starting Linbpq.

Now there is a possibility that when starting Linbpq with systemd a command can be given so that a PID file is created.

This is my linbpq.service file from systemd

[email protected]:~ $ sudo cat /etc/systemd/system/linbpq.service
[Unit]
Description=Linbpq Daemon
After=network.target
After=direwolf.target

ExecStart=/bin/bash /home/pd9q/linbpq/linbpq.start
WorkingDirectory=/home/pd9q/linbpq

[Install]
WantedBy=multi-user.target
Alias=linbpq.service

This command creates a linbpq.pid file, now it is possible that watchdog monitors linbpq.

ExecStartPost=/bin/sh -c "echo $MAINPID > /home/pd9q/linbpq/run/linbpq.pid"
[email protected]:~ $ sudo ls -l /home/pd9q/linbpq/run
-rw-r--r-- 1 root root 4 Oct 14 18:36 linbpq.pid
[email protected]:~ $

At the end of my watchdog configuration file (/etc/watchdog.conf) I have added the following line.

# Check if Linbpq is running
pidfile         = /home/pd9q/linbpq/run/linbpq.pid

Take a look at what happens when you stop Linbpq.

sudo systemctl stop linbpq.service

Yes the system is ReBoOtInG (I hoop)

Xfbb interface with Linbpq

In bpq32.cfg add

TNCPORT
COMPORT=/home/pi/fbbded
TYPE=DED
STREAMS=1
APPLMASK=4
ENDPORT

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

APPLICATION 3,FBB,,PI1LAP,LINBBS,255

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

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

Bpq32 Log options

John G8BPQ has made it possible to move the log dir of linbpq and pilinbpq. Nice

I’ve uploaded versions of linbpq and pilinbpq to my beta download site
that allow you to move the log directory. Start with a command line
parameter of logdir=directory, eg

../pilinbpq logdir=/dev/shm

 

You can download the new version here.

LinBPQ Applications Interface.

LinBPQ has a facility to make a tcp connection from the node to an application running on the same machine. This was originally intended to connect to a shell to enable basic configuration editing, but has been generalised to allow connects to other tcp ports, thus allowing you to write your own applications to be used with LinBPQ.

Edit
Henk, pointed out that there was something missing in this story. Nowadays we mainly work with Systemd in the newer version of Linux. So the inetd (internet super server) is no longer part of this. But you can still install it. “sudo apt-get install inetutils-inetd” or the successor to inetd the Xinetd “sudo apt-get install xinetd”
Thank you Henk…

Ok, that sounds nice. Let give it a try.

Fist setup Linbpq, add de “cmdport” to the telnet port section.

PORT
 PORTNUM=4                      ; Optional but sets port number if stated
 ID=Telnet
 DRIVER=Telnet

CONFIG
 CMS=1
 CMSCALL=PI1LAP
 CMSPASS=**********
 LOGGING=1
 DisconnectOnClose=1
 CMDPORT 63000
 TCPPORT=6309
 FBBPORT=6306
 HTTPPORT=****
 LOGINPROMPT=User:
 PASSWORDPROMPT=Password:
 MAXSESSIONS=10
 CTEXT=Welcome to PI1LAP`s Telnet Server.\nPress ? For list of commands \n\n
 USER=pd9q,pass,PD9Q,,SYSOP
ENDPORT

I have add “CMDPORT 63000” but it can by any number.

Now add a Application at the end of de bpq32.cfg

APPLICATION 7,APP,C 4 HOST 0 S

Now we have to add some stuff to /etc/services and /etc/inetd.conf

/etc/services

# Local services
bpqdemo        63000/tcp   # BPQ Demo App

/etc/inetd.conf

bpqdemo    stream    tcp    nowait    pd9q  /usr/local/linbpq/testapp.pl

Now restart inetd. sudo killall -1 inetd

I have found a small script on the internet and make some adjustments.
This script is using some perl modules that has to be installed.

cpanm Linux::SysInfo
cpanm Sys::Info
cpanm Sys::Load
cpanm Sys::MemInfo
cpanm Sys::CpuLoad

The testapp.pl script. /usr/local/linbpq/testapp.pl

#!/usr/bin/perl -w -T

# Simple information script 10/2018. PD9Q/PI1LAP

use strict;
use Sys::Info;
use Sys::Info::Constants qw( :device_cpu );
use Sys::Load qw/getload uptime/;
use Sys::MemInfo qw(totalmem freemem totalswap);
use Sys::CpuLoad;

   my $info = Sys::Info->new;
   my $cpu = $info->device('CPU');
   my $os  = $info->os;

   my $old_fh = select(STDOUT);
$| = 1;
select($old_fh);

my $line = <STDIN>;

   print "Hello " . $line . "Welcome to the LinBPQ System Info App of PI1LAP.\n";
   printf "\nWe have %s ", scalar $cpu->count;
   printf "%s-bit CPU", scalar $cpu->bitness;
   printf " %s\n", scalar $cpu->identify;
   printf "The CPU speed is: %s\n\n", scalar $cpu->speed;
   print "Operating System is\n", $os->name( long => 1 );

   print "\n\nSystem load: ", (getload())[0], "\n";
   print "System uptime: ", int uptime(), "\n\n";

   print 'load average: ',
       join(',', Sys::CpuLoad::load()), "\n\n";

   print "Total memory: ".(&totalmem / 1024)."\n";
   print "Free memory:  ".(&freemem / 1024)."\n";

   print "Total swap: ".(&totalswap / 1024)."\n";
   print "Free swap:  ".(Sys::MemInfo::get("freeswap") / 1024)."\n\n";
   print "Type exit to close\n";

while( my $line = <STDIN> )
{
    $line =~ s/\r?\n$//;
    if ($line =~ /exit/)
    {
                die "shutting down, bye,bye\n";
        }

        # do your processing here!

        print "  $line\n";
}

Now we can run the script from linbpq. Let give it a try.

With the help of the config file of Jerry, N9LYA and some help from John, G8BPQ I have setup a Winmor port on my Linbpq.I use a Microham USB II as soundcard device connected to my Windows PC and a direct Cat kabel from my Linux PC to control the TRX.

DireWolf/Linpq with Systemd.

I have a bad time behind me, I have had a lot of arguments with Systemd to start DireWolf and Linpq when booting 🙂
If you like Systemd, you can read some about it here https://en.wikipedia.org/wiki/Systemd

I want Linbpq to run under /dev/tty2 and DireWolf under /dev/tty3. This is because if I login remotely I can view the monitor from DireWolf with “conspy”. “conspy 3” Hit esc a few times to leave conspy.

Systemd does not want to accept the start line with >/dev/tty3 &

ExecStart=/usr/local/bin/direwolf -c /home/pd9q/direwolf.conf -l /home/pd9q/direwolf.log >/dev/tty3

This upper start line does not work.

So I had to come up with something else for that. So i wrote a start file. “direwolf.start”

cd /usr/local/bin
./direwolf -c /home/pd9q/direwolf.conf -l /home/pd9q/direwolf.log >/dev/tty3

Now i wrote a unit file to start DireWolf on boot.
/etc/systemd/system/direwolf.service

I had the same problem with Linbpq, which I solved in the same way.

cd /home/pd9q/linbpq
sudo ./linbpq  >/dev/tty2

Jeff have made some comments about it.

On HF I`d recommend starting with a maxframe other than 7.
With the Tracker`s intelligence I found it best to start 
connections on HF with a conservative value of maxframe = 1 then 
let the modem ramp things up if band/link conditions support it. 
Also suggest keeping a few hundred ms of @T2 in there to help slower radios.

Obviously VHF/UIHF is a different story, but suggest load testing 
different values and being careful if you`re going to have users with the 
Tasco (D72, D74, D700, D710 or KISS mode TNCs with no/minimal buffering connecting in. 
Be sure to test with transfers both ways and large enough 
(at least 7-8kb on the link) to bring buffering issues to light or nasty surprises may lurk.

Bind bpq to ax25 interface

I’m using uronode as front end node, but i’m also like to connect to different packet software.
This time it’s linbpq. Lets go…..

First of all bpq32.cfg
Change the comport to COMPORT=/dev

PORT
 PORTNUM=1
 ID=Link Local
 TYPE=ASYNC
 PROTOCOL=KISS
 FULLDUP=0

Axports

[email protected]:/usr/local/linbpq# cat /etc/ax25/axports
ax1     PI1LAP-9        19200   256     2       Linbpq pi1lap-9

Now the linbpq start file

setcap "CAP_NET_ADMIN=ep CAP_NET_RAW=ep CAP_NET_BIND_SERVICE=ep" linbpq

# Link local pi1lap-9
        echo "Starting ax1 "
        if grep ax1 /etc/ax25/axports ; then
        tmpfile="/tmp/$.startax5.pts"
        kissnetd -p 2 > "$tmpfile" &
        sleep 2
        attachthem () {
                read PTS1 PTS2
                kissattach -l $PTS1 ax1 44.137.31.73 || return=$rc_failed
                ifconfig ax1 44.137.31.73 netmask 255.255.255.224 up
                sleep 1
                sed -i "s,COMPORT=/dev/.*$,COMPORT=$PTS2," /usr/local/linbpq/bpq32.cfg
        }

        tail -n 1 $tmpfile | attachthem
        rm $tmpfile
        sleep 3
        else
               echo  "Error ax1 not found in the file axports"
                return="Failed"
        fi
        echo "$1 $return"

cd /usr/local/linbpq
sudo ./linbpq  >/dev/tty4

Ok let’s look it ok now

ps ax | grep kissattach

[email protected]:/usr/local/linbpq# ps ax | grep kissattach
 5910 ?        S      0:00 kissattach -l /dev/pts/16 ax1 44.137.31.73
 6504 pts/19   S+     0:00 grep kissattach

Now have a look in bpq32.cfg

[email protected]:/usr/local/linbpq# grep COMPORT=/dev bpq32.cfg
 COMPORT=/dev/pts/17

Here you see there is a PTS couple /dev/pts/16 and /dev/pts/17

So we are good to go.

         cd /jnos

         mkdir users		* you only need to do this one time

         ./jnospwmgr -a <callsign> -w

         it will ask you to enter the phrase that you would have received
         from your winlink notice (the challenge/response phrase).         

       * for now please read release notes (search December 8) for more info.

   Remote LINFBB host
   ------------------

     For forwarding to VE4KLM I added the following line to 'bbs.sys' :

       < FWD\VE4KLM

     A forward file for that particular bbs is placed in FBB's 'fwd' directory,
     so an example of forward file, 've4klm' (contents might be different for
     other FBB owners.)

       A VE4KLM

         P A
         C C ve4klm ve4klm.ampr.org 6300
         V login$Wpassword$W

       #  Forward file -- To VE4KLM BBS (JNOS)
       #
       #  Personal mail
       #
       B VE4KLM
       F VE4KLM
       #
       # Reverse fowarding to take place
       R
       # Forward rest of North-America to VE4KLM
       H  VE4KLM.#WPG.MB.CAN.NOAM
       H *.NOAM
       #

   Remote BPQ host
   ---------------

     This is needed as telnet connect script for bpq in forwarding with jnos.
     It is entered in the "connect script" box of the forwarding config web
     page of the bpq mail server.

       TIMES 0000-2359
       Idletime 60
       attach 3
       c ve4klm.ampr.org 23 NEEDLF .login pass

     General:

       attach p - p is a port number cfg'd as telnet port in your bpq32.cfg

       c Hostname TCPport [NEEDLF] User Password [Command]

     Here :

       attached 3 - I configured port 3 as telnet port
       NEEDLF     - Causes a Line Feed to be sent after user and password.
       .login     - The period before the login user name will tell jnos to use
                    a transparent TCP session instead of ordinary telnet.

     See: http://www.cantab.net/users/john.wiseman/Documents/TelnetServer.htm

     This example line below is needed in bpq32.cfg so that jnos can login into
     bpq and initiate forwarding as bbs.
