Ok gave up on other fixes..downloaded the fresh Draws version 16, wrote it to a new unused sd card...

...started from new on the 'Getting Started' https://nw-digital-radio.groups.io/g/udrc/wiki/8921

cd
cd n7nix
git pull

sudo su
apt-get update
apt-get dist-upgrade


(BTW at this point you need to 'exit' root in order to do the next two steps)

cd
cd n7nix/config
# Become root   (again)
sudo su
./app_config.sh core

During that ./app_config.sh core   I get the following messages...

== setup iptables
iptables v1.8.2 (nf_tables):  RULE_APPEND failed (No such file or directory): rule in chain OUTPUT
iptables v1.8.2 (nf_tables): Couldn't load match `udp':No such file or directory

I rebooted as directed and guess what... Chromium still attempts to ride on UDR0:

udr0: fm KF5DEY-10 to QST ctl UI pid=CC(IP) len 195
IP: len 195 192.168.255.2->239.255.255.250 ihl 20 ttl 1 DF prot UDP
UDP: len 175 57908->1900 Data 167


Again, this was a brand new sd card, fresh download of draws version16, ran ./app_config.sh core
as described...

Something is wrong somewhere...

I can take the NWDR image, burn it to an mSD card & configure some HAM

would allow you to do the same. If you find that useful, great.

Teamviewer install on Raspberry PI

J P Watters <kc9kko@...>
 

Basil,

Rather than HIJACK another thread, I recommend the installing Teamviwer on Buster to be able to remotely assist others with issues.

  • Install Teamviewer

# install teamviewer for virtual remote desktop access

cd  /home/pi/Downloads

mkdir teamviewer 

cd teamviewer
I currently use version 15 so I don't encounter too new of software the forces upgrading the client.

wget http://download.teamviewer.com/download/linux/version_15x/teamviewer-host_armhf.deb

 

sudo dpkg -i teamviewer-host_armhf.deb

 

Installing teamviewer often results in missing dependancies.

after teamviewer install fails run sudo apt --fix-broken install -y

 

sudo apt --fix-broken install -y

 

grep -i eula /opt/teamviewer/config/global.conf

# Should result in finding a line containing [int32] EulaAccepted = 1

#

# edit the /opt/teamviewer/config/global.conf 

# insure that there is a line EulaAccepted = 1 in the file.

#

# [bin  ] EnterpriseUIState = 

# [int32] EulaAccepted = 1

# [int32] IPC_Port_Service = 5942

#

 

#get teamviewer id

teamviewer info

 

#set a Teamviewer password 

# sudo teamviewer passwd [password]

# ie. sudo teamviewer passwd itisasecret  

 

sudo teamviewer passwd whateveryoutypeherebecomsethepassword

 

# restart the Teamviewer service      

sudo systemctl restart teamviewerd





Then from your TEAMVIEWER platform of choice, connect the the id.


Re: Chromium issue...

I would like to point out that I was running an image, did the
appropriate updates etc...for a few months... then probably something
I did broke the iptables...
I know passing emails back & forth is not very satisfying when trying to
fix problems. If I was in front of your RPi I could fix your problem
in short order so it is a little frustrating for both of us.

...so I can start over (the equivalent of reinstalling windows) but
chances are good I will successfully break iptables again.
I would like to know how you do that so I could make the configure
scripts more robust.

I am not saying it is your fault...Chromium is the issue...but
iptables is the weakness that Chromium is exploiting.
iptables is the solution to fixing a Chromium problem that binds to all
network interfaces.

I will work on what you wrote, and see if I can work around this...
Try running the iptable_install.sh script by itself. Then look for
this file:

/lib/dhcpcd/dhcpcd-hooks/70-ipv4.ax25

It needs to have the following line in it that will allow iptables rules
to be loaded at boot time.

iptables-restore < /etc/iptables/rules.ipv4.ax25

Re: #wl2kax25 #wl2kax25

Hi Ed,

Does the /usr/local/etc/wl2k.conf need to stay as udr0 or can I change
it since I am wanting to use udr1 for EMAIL and leave urd0 for APRS as
the frequesncies are different?
Yes that is exactly right. Change 'ax25port=' to which ever port you
will be using for Winlink messaging, then you will not have to bother
with setting that argument on the command line.

Re: Chromium issue...

If you use an NWDR SD card image and follow the "Getting Started"
instructions then iptables will get installed properly. Along with
iptables, the iptables-persistent package also gets installed.

Running iptable_install.sh script by itself MIGHT work to fix your
problem. Running ./app_config.sh core as is described in the "Getting
Started" WILL definitely work because that is what I test.

One of the things the iptable_install.sh script does is it creates a
/lib/dhcpcd/dhcpcd-hooks/70-ipv4.ax25 file that restores iptables rules
from a boot. That is most likely missing in your current setup but might
not be the only thing missing.

I would recommend starting with a fresh NWDR image & following the
"Getting Started" Guide.

It seems to have solved the problem.
Happy that's working for you.

iptable-check.sh - Lists current iptables rules
iptable-flush.sh - Clear all iptables rules
iptable-up.sh - Add all iptables rules

So another lesson learned.

Re: #wl2kax25 #wl2kax25

Basil Gunn
 

Hi Ed,

-a udr1

like this:

wl2kax25 -a udr1 -c n7nix-10

You will be overriding whatever is in your /usr/local/etc/wl2k.conf
configuration file. Take a look at the 'ax25port= ' line which should be
ax25port=udr0

Make sure your ALSA settings are correct for both radios on left & right
channel.

What value should it be for PORT1 of the DRAWS?

Re: Utilizing DRAWS to encrypt handheld radios

Using encrypted radios is completely legal in the US.  the FCC rules are more based around the language of frequency and tx power.
If you're talking commercial-band stuff, then yes, encryption? Sure,
knock yourself out. Amateur bands? Well, that differs.

Here in Australia, it is permitted for emergency communications and in
EMCOMMS exercises, as well as for remote control of equipment.

I understand the FCC rules are a lot more strict on this and do not
allow EMCOMMs traffic to be encrypted.

The real question is, "what hand-held radio"? They come in all shapes
and sizes from your $2 AM set that maybe puts out 10mW and is set by a
crystal in the upper HF… right through to eye-wateringly expensive TETRA
and DMR hand-held radios which likely do their own encryption.

The former could be "encrypted"… you'd just have to interface to the PTT
(fun, because sets of that vintage often used multi-pole switches so
they could cheap out on the transistors), but would be illegal to do so
as I'm pretty sure any kind of data communications at 27.145MHz would be
a violation of the Citizen's Band Radio Service Class License (or
rather, its US equivalent). This is also the case for the more modern
UHF CB sets at 477MHz.

Amateur: again, depends on the scenario, sometimes it's legal, most of
the time it isn't, so most of us have not bothered. QSSTV does work on
the Raspberry Pi, can send files using HamDRM, and HamDRM does not care
if you're sending a photo, plain text, or a blob of data encrypted using
openssl/GnuPG/whatever crypto tool.

Anything else you can get hold of as a mere mortal… smart money would
say it's not legal to use encryption on that band.
