Hi @mikerjensen as the original requester (#1664) can you please review and/test Tim's PR #1665 here?

Thanks if possible!

(Tagging @georgejhunt @jvonau @m-anish who might also be to help?)

The proposed changes look good to me, but it's not apparent to me how to test them.

@mikerjensen can you let us know if the following works!?

sudo su -
cd /opt/iiab/iiab
git checkout -b tim-moody-samba-ports master
git pull https://github.com/tim-moody/iiab.git samba-ports
./iiab-network    # this command arranges IIAB networking -- plz make sure your WiFi/Ethernet/routers are all plugged in (or unplugged from!) IIAB according to your final configuration, before running this command

PS normally you'd run the command /usr/bin/iiab-gen-iptables whose source code is here: https://github.com/iiab/iiab/blob/master/roles/network/templates/gateway/iiab-gen-iptables

Sorry i'm such a noob at this, i ran the below three lines from the above:
sudo su -
cd /opt/iiab/iiab
git checkout -b tim-moody-samba-ports master

and on the last line I got:
fatal: Cannot update paths and switch to branch 'tim-moody-samba-ports' at the same time.
Did you intend to checkout 'master' which can not be resolved as commit?

Not sure what to do next.

@mikerjensen ok! Let me tentatively merge this so you can test from our master branch. I can always revert it later if nec.

So...please now run the following:

sudo su -
cd /opt/iiab/iiab
git checkout master
git pull
./iiab-network    # this command arranges IIAB networking -- plz make sure your WiFi/Ethernet/routers are all plugged in (or unplugged from!) IIAB according to your final configuration, before running this command

Does that solve your Samba problem?

Sorry,
'git checkout master'
results in:
error: pathspec 'master' did not match any file(s) known to git.

'git checkout master'

Did @mitra42 build these machines? Perhaps I wrongly assumed you were on IIAB's master branch.

So just manually install the 2 necessary files:

cd /opt/iiab/iiab/roles/network/templates/gateway/
mv iiab-gen-iptables iiab-gen-iptables.bkp
wget https://raw.githubusercontent.com/tim-moody/iiab/94eba076368ff21a5e7fcdd22dd55f723a690235/roles/network/templates/gateway/iiab-gen-iptables

cd /opt/iiab/iiab/vars
mv default_vars.yml default_vars.yml.bkp
wget https://raw.githubusercontent.com/tim-moody/iiab/94eba076368ff21a5e7fcdd22dd55f723a690235/vars/default_vars.yml

cd /opt/iiab/iiab
./iiab-network

Does that solve your Samba problem?

Yes, sorry, i have installed IIAB via /usr/sbin/iiab with a modified line 179:
git clone https://github.com/mitra42/iiab -b distweb --depth 1
I'm not sure running /usr/sbin/iiab again will pull these new files,
so i tried running the commands you suggested in message above, but it didn't fix the samba problem, and the RPI was still unpingable via eth0. I did notice that after running the above commands /etc/iptables/rules.v4 had not changed (including after reboot) so i figured there was still an intermediary step i missed. I assumed it was 'install configured options' in the iiab admin menu, so i ran this, and iptables/rules.v4 did indeed change, dropped in size from 2204 bytes to 765 bytes. And SMB now works via eth0!

@mikerjensen can you take a quick look at PR #1677 which should make your life a great deal easier, after I hopefully merge it along with Internet Archive functionality in the coming 24h?
