Installing openvpn on Linux Debian wheezy 7

I have installed openvpn on my Debian system so it’s possible to surf with my winhoos laptop on the amprnet. Work quite nice

In this description I do not give much text and explanation. On the internet there is plenty to find about configuring openvpn.

This is what I use, it’s a simple setup.

sexy ifconfig

ax0 voor link fbb
ax1 voor link Convers
eth0 Dit is de Baas
sl0 voor (X)net
tun0 voor Jnos
tunl0 voor ampr Gateway

Om te zorgen dat de data gaat lopen hebben we een aantal ip routes nodig.

ip route add dev sl0 table 44 src
ip route add dev tun0 table 44 src

En voor de iptables firewall
$ipt -A FORWARD -i tunl0 -o sl0 -j ACCEPT
$ipt -A FORWARD -i sl0 -o tunl0 -j ACCEPT
$ipt -A FORWARD -i tunl0 -o tun0 -j ACCEPT
$ipt -A FORWARD -i tun0 -o tunl0 -j ACCEPT

Met deze bovenstaande regels heeft iedereen toegang tot sl0 en tun0

Tcp Access Control Jnos

Jnos works with an access control list. Here a small example what you can put in there. There are things double in it, this is just an example what is possible


Xnet axudp link Jnos

The axudp link from xnet to jnos has caused a lot of problems.
But he is up and running … Here the explanation.

In the line “attach axudp xnet 256” (jnos) is the secret.
This must therefore “not” refer to the ip address of xnet like you
have indicated in at myip, but to the IP address of Linux itself.
So the ip address of (for example) eth0

Autoexec.nos (Jnos)

Eth0 (Linux) (xnet) (xnet)


Monitor script F6fbb

Brain N1URO has written a script to see if fbb is still running.
I saved this script in the fbb directory.

Have it saved as “fbbcheck” now it is possible to call it via a cronjob every hour.

Edit the /etc/crontab file and add the following.

Now, every 15 minutes after the full hour, it is checked whether fbb is still running, otherwise it will be restarted.

Here under the “fbbcheck” script.

Tnx to Brain N1URO

I made a small addition to the script myself. Now I can also see how long fbb has been running and when fbb has been started. (just fun )

Looks like this.

Examples forward JNOS/BPQ/LinFBB

Here below some examples how the configuration of the forward in different systems works.

Thanks in particular to Bob (VE3TOK) and Gus (I0OJJ) for example configs !

Start DXSpider bij het booten

Om DXSpider te starten bij het booten, moet er wat aangepast worden in de /etc/inittab.
Eerst moet onder staan de regel worden uitgeschakeld, hier kan simpel een # voor.

We gebruiken tty6 voor DXSpider, dus deze moet worden uitgeschakeld.
Nu kunnen we de onderstaande regel toevoegen aan de /etc/inittab

Start Jnos on bootup

To start Jnos when booting, you have to adjust something in the /etc/inittab.
First the line “#2:23:respawn:/sbin/getty 38400 tty2” must be switched off , a simple # can be used.

We use tty2 for Jnos, so it must be disabled.
Now we can add the line below to the /etc/inittab

Start file for Jnos

Now Jnos is automatically started with every reboot of the system.


Linux Iptables Blok een compleet land.

Hier onder een iptables script wat het mogelijk maakt om hele landen te blokken.
Op staan de landen files die je kunt gebruiken.

Installeer DxSpider op Debian Wheezy

# Install Dx-Cluster

sudo apt-get install wget
sudo apt-get install git-core
sudo groupadd spider
sudo useradd -m sysop -G spider
sudo usermod -g spider sysop
sudo passwd sysop
sudo adduser sysop sudo

# Perl modules
sudo apt-get install libtimedate-perl
sudo apt-get install libnet-telnet-perl
sudo apt-get install libcurses-perl
sudo apt-get install libdigest-sha-perl
sudo apt-get install libdata-dumper-simple-perl

sudo su
cd ~sysop
ln -s /home/sysop/spider /spider
shutdown -r now

After restart login as sysop
cd ~
mkdir spider
git clone git://
cp -a /home/sysop/ /spider
rm -rf
cd /spider
git reset –hard
sudo su
cd /home/sysop/
chown -R sysop.spider spider

find . -type f -exec chmod 775 {} \;
cd /spider
mkdir local
mkdir local_cmd
cp perl/ local/
cp perl/ local/
cd local
– edit following the instructions in the comments
– edit to remove “#” from the line for the port, and add additional ports as needed:
@listen = (
[“”, 7300],

cd /spider/perl/
cd /tmp
# The next step can take a few minutes
/spider/perl/ /tmp/usdbraw.gz
cd /spider/src
cd /spider/perl
# on a separate ssh or system console, log into the system as sysop
# from the command line of the console enter:
load/usdb # US database ?

# Edit /etc/inittab to add the following two lines at the end of the file.
##Start DXSpider on bootup and respawn it should it crash
DX:2345:respawn:/bin/su -c “/usr/bin/perl -w /spider/perl/” sysop >/dev/tty6

Add a line to /etc/services and /etc/inetd.conf for spider

# Local services
bpqspider 7400/tcp # BPQ to Spider Link


sudo apt-get install openbsd-inetd

bpqspider stream tcp nowait sysop /spider/src/client client login ax25

Restart inetd – sudo killall -1 inetd
