I have direwolf with QtTermTCP running with a DINAH with no issues. The hardware is hooked up and working. The system is using the CM108 chip and again it works ok?

When I run PAT on the same system the hardware does not key up..

This is what I see when I start direwolf.

Ok.. that looks good.

Ok.. so this doesn't look like it has anything to do with direwolf, etc.? Few things:

?? - what does "ls -la /tmp/kisstnc" show?
?? - what does "ls -la /dev/pts/*" show?

If you run "sudo su" and then run "kissattach /tmp/kisstnc radio", does it work?

Seems you should fix the perms here so you make systemd happy.

Per my test above, not everything works properly with sudo.? Usually, issues are seen when using redirects, pipes, etc. and a simple command like kissattach should work but I'm not 100% sure.? The above test will help you narrow that down.

Hi David, I think this is what your asking for:

Hello Darrell,

I have a service I wrote to start direwolf on boot up but I have two issues with this. First it works but does not create the virtual tnc.? if I add the "-p" in the service I get a permission denied when trying to attach the kisstnc.

Can you show us the output the of journalctl lines when you get this permission denied error?? I confirmed the other day that Direwolf does NOT need to run as root with the -p option.

First is there a way to run direwolf as a service and still get a virtual tnc?

Well.. the issue here is that to have a complete LInux AX.25 stack, you need to run a lot more than just Direwolf.? You need to at least run kissattach and kissparms as well to properly configure the stack.? Yes, you can make both of those programs as systemd units and work on getting all the dependencies figured out so that if say Direwolf dies and Systemd restarts it, Systemd will kill the old kissattach process, restart it and also re-run the kissparms command as well.

Second is there a way to attach the kisstnc from within the service itself?

I personally haven't tried to run all these different Linux ax.25 bring up/down commands via a systemd.? Maybe it's possible but I've always seen that a systemd unit only runs ONE command, not multiple.? There are various websites out there that talk about this though.? Search for "linux ax.25 systemd unit"

??

In this example, this person is not using Direwolf but just using a KISS TNC but regardless, they are running things as ROOT and also is just using systemd to run a script of commands.? I think calling out a script of commands for bringup / down is probably the sane thing to do.

[Service]

User=pi

ExecStart=/usr/local/bin/direwolf -t 0 -c /home/pi/direwolf.conf -p

StandardOutput=syslog

StandardError=syslog

SyslogIdentifier=direwolf

Are you 100% sure that the "pi" user has the "dialout" group permissions as well as anything else required to operate properly?? I would bet this is where your above "permission denied" errors are coming from.? It is worth mentioning that I do believe that "kissattach" must be run as root.

Hello Ryan,

Rob is spot on on things to look at though I would offer some additional troubleshooting tricks.? You are stating you're both not being heard (aka.. an issue with your transmissions) and what you hear is too low (aka.. a receiving problem).?

?? - Take an amplified speaker and connect it to end of the the cable that's supposed to plug into the Direwolf soundcard.? Use alligator clips, etc. to make the connections and this step will help you confirm your cable is wired correctly, etc.? You MUST hear all the packet sounds when say tuned to 144.390

?? - Take an amplified speaker and connect it to end of the the cable that's supposed to plug into the Baofeng's microphone input.? Use alligator clips, etc. to make the connections and this step will help you confirm your cable is wired correctly, etc.? Now reconfigure Direwolf to send a beacon say every 60 seconds and make sure you hear sounds when it transmits.? It's worth noting that Baofeng radios are renown for incorrect dimensions for the speaker/microphone jacks and you need to shave off some of the plastic on the connectors going into the radio or you'll never have a reliable connection. See the top entry in this FAQ:

???


Overall, Baofeng radios can be made to work but they are renown for being inconsistent from one radio to the next, being very flaky, and downright unreliable.? With a lot of persistence, I bet you'll get it working but many people recommend to spend a little more money and get a better radio for reliable packet operations.? Up to you but I thought I'd put that warning out there.

All, thanks for reading. I am trying to get my club back into packet and maybe then APRS later on.? I am modifying HAMPI because it already has a bunch of great tools for the club to run QTterm and PAT.

First
If I start direwolf as a script it runs great with QTtermTCP using AGW.
After asking questions last week I was told to add the "-p" to have it create a virtual kiss tnc for PAT
I did this and again it all seems to work.

I have a service I wrote to start direwolf on boot up but I have two issues with this. First it works but does not create the virtual tnc.? if I add the "-p" in the service I get a permission denied when trying to attach the kisstnc.

First is there a way to run direwolf as a service and still get a virtual tnc??

Second is there a way to attach the kisstnc from within the service itself?

This is what I have:

Hello,

Thanks for the input. I am at work now, but I'll go through your steps and recheck everything. I reinstalled all software yesterday.?

When my truck APRS signals a beacon, my direwolf is picking it up on the screen. However, when I go to APRS.fi it doesn't show my mobile station listed as a station 'directly heard' by my digitpeter.?

In fact, I have never had any stations directly heard by my station ever, despite multiple stations being near me. Is there something I'm missing?

Thanks for your help,

Hello. I have direwolf running on a Raspberry Pi 4 with a UV5R and a magmount antenna. I have gotten direwolf and xastir running, however the output on direwolf after it loads is 0(0/0) or 1(0/0). When I check my digitpeter on the APRS website, nobody is hearing me (even when I have my APRS mobile in the driveway 20 ft away). I have messed with the soundcard, traded out radios, tinkered with the mixer, etc. I have tried reinstalling and following other peoples videos/websites for installation without success. Anyone happen to know what my issue may be??

Also get this error:

I was working on this project tonight as i have direwolf snd hamlib running on a raspberry pi. Id reslly like to get this working on the windows laptop but i run into this issue (please see the right terminal window):

I think I found the issue although I don't know how to fix it ... I'm not that good at linux commands.

I changed directory to direwolf10-28-10 ? ?which I think is the day I downloaded the v1.6
from there I ran direwolf and it started.
Looks like I need to fix the program name on /

How?

I have tried using sudo but since direwolf is giving an error I assume its opening without the sudo so the issue is not permissions.?

play -l shows 3 cards, the important one being?
card 2: Device [C-Media USB Audio Device], device 0?: USB Audio [USB Audio]

I've rebooted this Raspberry Pi 15 times or more working on this so I don't think another instance of Direwolf is running.

This is v5.4.79-v7+

Which translates to Buster Version 10

Completely updated and upgraded.

Darn error correction. YES plughw:1,0 but it is a plight... LOL

Here is a clue:



Did you mean to say? plughw:1,0? ?
