Multiple Hosts and SSIDs

[Joe Tennis]

First off, Awesome project!! This is my second path down DigiPi Ally; the first time as a curious observer, and this time I seem to have a digipeater up and running! 

I'm fairly technical - have run web servers and *nix boxes, and work in technology, but like many I've been reading from on this list, I lack the general topology of how everything fits together... So I'll attack the questions I'm bumping up against one or two at a time, and see what I can figure out.

First, host names:

Since I don't have any friends I need to have two of everything, so I have two DigiPis - one on a rPi4 I plan to leave at home, and one on a 02W I plan to have in my car/travel gear. But, there are times where they'll be in range of each other so I reckon I need different hostnames, and probably SSIDs after my call, similar to the plethora of MMDVMs I have for DMR. Right?

So:

/etc/hosts

/etc/hostnames

Those're the only places I need to change domains, right? 

Then, SSIDs: Initialization gave them both -2, which I don't prefer for a computer-based setup, so I've changed the rPi4 to SSID:  -10 near the top of direwolf.digipeater.conf

• Then I peaked under the hood of direwolf.tnc.conf, direwolf.tnc300b.conf, direwolf.tracker.conf and saw -2 there too... Safe to change these to -10 too?
  
• I see it as -4 in direwolf.node.conf and that's kinda interesting, especially since I prolly use that -4 somewhere across my 4 aprs HTs, 4 Androids, and my main digital mode laptop... not sure why it's a different SSID, though I'm convinced there's a reason.
• Ah! and direwolf.winlink.conf uses -10, so will that confuse things if I use that in the others?

Do you have an audit of all the places I'll need to ferret them out? I'm sure I could do some clever python thing, but I thought I'd ask. Any theory or advice here would be most welcome!!

again, wonderful work - I love such solid dev-ops-esque thought going in to this rather complex end of the hobby!

There will be more to follow around how all this works together, but for tonight:

73,

Hi Joe - great questions!

Yup, edit /etc/hosts and /etc/hostname  (and/or /var/www/html/header.php).
If using wsjtx/js8call, run those apps once *after* pressing [save configuration]
to write out a .new Xauthority file.

Do not use an SSID during Initialization.

SSID's are different for each mode.  You can edit them in each of the
direwolf .conf files in /home/pi .

You already discovered some collisions too - so be careful there.  -10 is
almost always winlink.  checkout /etc/ax25/axports there.


American River?  I can walk there from here (confluence).


cool,

OK, So:

HOSTNAME(s)

in /etc/hists I commented out all your numbered hosts and added a line of my own:

#127.0.1.1      digipi digipi2 digipi3 digipi4
127.0.0.1       digipia

Kosher?

then in /etc/hostnames I edited its lonely little line to be:

digipia

That seems to work...

and did thusly with my "b" (mobile) pi

tbh I haven't even launched JS8Call yet, much less WSJTX, and to be even more forthcoming, I never really noticed the "[save configuration]" and can barely fathom what it does... see earlier comment about not groking the "topology" of this partly-locked-down file system. It certainly compartmentalizes things, which seems to simplify learning all the constituent parts...

I also changed the header at /var/www/html/header.php but a note to others trying to be cute and customize things (and Craig, correct me if I'm wrong):

Don't edit the TITLE of that screen as direwatch.sh is looking for it later, or something like that seems to be happening

SSIDs

No, didn't try to set at initialize - good callout though!

So, here's my plan. More or less based on convention from https://www.aprs.org/aprs11/SSIDs.txt I'm thinking the following for my two systems: 

digipiA being my Pi4 which will stay static in my shack and 

digipiB is my little zero2W in my car or backpack with a hotspot which will occasionally come up tot he shack for care and feeding

Next up will be some PTT questions, and Sound Levels!

and yes, lived on Little Rd less than 1/4 mile from the bridge back in the early 90s. Worked at Rapid Shooters which was where Troublemakers is now. Could walk to the Coloma Club. Fun times!

[Craig]

I added the 2, 3, 4, etc, so you could then append to that line with
your hostname. 

127.0.1.1      digipi digipi2 digipi3 digipi4, digipia

Do not edit 127.0.0.1, that's really reserved as "localhost"

Thanks! Makes perfect sense - more to follow :)
