Re: Chromium issue...

Thanks for the console output.

The raspbian distro version of iptables has recently changed and no
longer allows setting iptables rules without the ax.25 interface(s)
being up. That means the place where iptables was previously config'ed
in './app_config.sh core' no longer works. I have made some changes to a
number of scripts and need to do more verification but running the new
iptable-check.sh script should fix your problem.

# First start the ax25 interfaces if you haven't already done that

ax25-start

# Then refresh the n7nix repo on your RPi

cd
cd n7nix
git pull
cd config
./bin_refresh.sh

# Now run the new iptable-check.sh script and verify

iptable-check.sh

I would appreciate seeing all the console output from this script.

If the above doesn't work then delete the following two files:

/etc/iptables/rules.ipv4.ax25
/lib/dhcpcd/dhcpcd-hooks/70-ipv4.ax25

and run iptable-check.sh again.

/Basil

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*

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...
