Re: GPS "Status Reporting" (GPSD/Direwolf)

 

Hi John (et. al.) -?

There is a line in the reports produced by [cgps / gpsmon -n] that is entitled "Status", which in APRSIS/32 can be stripped from the header NMEA text and included in the APRS station beacon so that the receiving stations can see my GPS dongle's 3D lock.? Does that clarify what I'm trying to do?

Ciao & 73,?

GPS "Status Reporting" (GPSD/Direwolf)

 

Hi folks,?

I'm running Direwolf on a Rasberry Pi with a cheap GPS dongle.? I am wondering if there's a way to get Direwolf to beacon the GPS receiver's status?? Any thoughts would be appreciated.

Ciao & 73,?

Re: Direwolf to send to Igate server AIS ship information

 

Did you put "-A" on the command line to convert AIS sentences to APRS objects?
Direwolf to send to Igate server AIS ship information

 

So I am testing the Direwolf AIS option.

?

Need to make sure that I am interpreting this correct.

?

If I capture AIS information in my area can Igate that to APRS.FI?

?

So this is a sample what I am Igating, I do see go the information on the screen after it connects to an Igate server.

?

Does this looks correct?

?

I have gone to APRS.FI but don’t see any ship tracks on the map from my station.

Re: Need help with kissattach TIOCSETD error

 

An older version of the User Guide had this.
It was removed after it did not seem to be a problem anymore.
I don't recall the specifics right now.
If neither of them solved the problem, I don't have any other ideas.
Maybe this will jog someone's memory about the problem.


5.6.2.1 ????? Troubleshooting – kissattach? failure

?

Sometimes kissattach has an issue with the Dire Wolf pseudo terminal.? This shows up most often on Raspbian but sometimes occurs with other versions of Linux.

?

kissattach: Error setting line discipline: TIOCSETD: Device or resource busy

Are you sure you have enabled MKISS support in the kernel

or, if you made it a module, that the module is loaded?

?

The root cause and a proper solution have not been found yet.? For now, two different work-arounds are available.

?

5.6.2.2 ????? First Work-around

?

IZ1YPS came up with this interesting work-around.

?

(1)??? Start up direwolf with -p option as you normally would.

?

(2)??? Rather than putting the pseudo terminal slave name (/dev/pts/…) in the kissattach, use /dev/ptmx instead.? Example:

?

sudo /usr/sbin/kissattach /dev/ptmx radio 44.56.4.118

?

??????????????? It should respond with something like this:

?

AX.25 port radio bound to device ax0

Awaiting client connects on

/dev/pts/5

?

??????????????? Remember that last line because it will be used in the final step.

?

(3)??? Connect them with mkiss.

?

sudo mkiss /tmp/kisstnc /dev/pts/5

?

The last command line argument is the result from step 2.? If you wanted to script those last two steps, you could do it like this:

?

x=`sudo /usr/sbin/kissattach /dev/ptmx radio 44.56.4.118 | tail -1`

sudo mkiss /tmp/kisstnc $x

?

?

5,6,2,3 ????? Second Work-around

?

Rather than using the pseudo terminal feature of Dire Wolf, use the TCP network KISS port instead.? AB4MW pointed out that “socat” can be used to create a pseudo terminal for use by other applications.? First install “socat.”?? On Debian / Ubuntu / Raspbian systems, the command is:

?

sudo apt-get install socat

?

Run “direwolf” without the “-p” option.? Among the start up messages you should see:

?

Ready to accept KISS client application on port 8001 ...

?

Now create a two way connection between port 8001 and a new pseudo terminal in a different command window.

socat PTY:raw,echo=0,link=/tmp/kisstnc TCP4:127.0.0.1:8001

Use the result with kissattach.

?
Need help with kissattach TIOCSETD error

 

Folks,
I am trying to get Dire Wolf installed on a Jetson Nano (4 gb version).? It is running Ubuntu 18.04 LTS.

The issue I am running into seems identical to a bug fixed in version 1.4?
- When I issue this command:
??? "kissattach /tmp/kisstnc wl2k"

- I get this error:
??? "kissattach: Error setting line discipline: TIOCSETD: Invalid argument
???? Are you sure you have enabled MKISS support in the kernal
???? or, if you made it a module, that the module is loaded?"

The first time I hit this error I reflashed the Jetson Nano OS memory card
with a clean copy and compiled Dire Wolf 1.6 from source.? I got the same error.

Then I built Dire Wolf 1.7 from source and got the same issue.? I have multiple
Raspberry Pi's happily running Dire Wolf.

It seems like this has been fixed before.? Is there something special about
the Ubuntu OS?? I actually found the 2 work around suggestions for this issue
in the user guide for version 1.4, but neither of those worked for me either.

Any suggestions for other things to try would be greatly appreciated.

Thanks in advance.

Kind regards,

Mike

Indeed, U+2013 is the En Dash character (–), which is distinct from the U+002D hyphen character (-), so that’s undoubtedly what’s going on here.

This is a common problem on sites like WordPress blogs, which are designed for formatting text and automatically format quotes and dashes unless the author surrounds their code in <code> tags.
Re: ALSA lib Unknown PCM

 

I've also seen this type of issue when using copy/paste from some documentation.
Some word processors will change the ASCII "-" (minus sign, dash) to some other character that looks the same but has a different internal representation.
If you got this error after a copy/paste from some documentation, try typing it on the keyboard instead.

There is a difference between the Range ( r/ ) and Type ( t/ ) filters.
Range ( r/ ) "Pass posits and objects within dist km from lat/lon."

Indeed. This is one of the most common errors I have seen, where someone chooses _not_ to send their beacon to the APRS-IS backbone (for whatever reason), and then expects the backbone to know where they are to calculate the circle center for the m/ filter.

Arnold,

I've seen this occasionally when trying to use my-position filter like your t/m/<callsign>/<distance> and found that the problem was it didn't apply the filter because that particular server didn't know my current position.? It's more reliable to use an explicit range filter, like this:? r/37.95/-91.77/100 (this is for my position, it's "r/<latitude>/<longitude>/<range_in_km>").? Try that using your lat & lon and see if it fixes your problem.

Hello Alfred,


I get the following error message(s):
Reading config file direwolf.conf
Audio input device for receive: \u2013p? (channels 0 & 1)? <------------------------------------

Ah... interesting.?? See that "\u2013p" text?? That's showing what Direwolf is trying to use as it's input soundcard when it loads.? To see what this string is, type in that text to a Unicode converter such as:

??

What's the output?? It's "-p"!? More on this in a moment.


arecord -l

Ok.. seeing this output confirms you have a different language file enabled on your Raspberry Pi.? That should be perfectly fine BUT I haven't seen many users doing this so there might be some Direwolf parsing bug.? I will admit I'm surprised this is happening as Direwolf is used by a LOT of people.? As an experiment, try running the following command from a terminal window:

?? sudo raspi-config

and go to:

????? localization options --> Locale

which locales do you have enabled (there can be multiple)?? On my Rpi 3B+ running Raspberry Pi OS version "Buster", I have "en_US.UTF-8 UTF-8".? I believe you're from Germany so you might try using ONLY the "de_DE ISO-8859-1" option just as a test.? Once you select the new language package, you need to select OK, select the ISO option again, and then the system will build the package and enable it.? After that, select "Finish" and if the tool doesn't prompt you to reboot, I recommend to do so with a "sudo /sbin/shutdown -r now".? Once the system reboots, you should be able to still log in and read everything in your native language.

At this point, try starting direwolf again and see if it's still complaining about this "\u2013p" text.

t/ is the type filter. m/ is the "me" filter (range around my station position).

?? - Arnold reaches out to these two APRS-IS owners and have them fix their systems or take them down.? If there isn't any response, I would recommend to take this up with the main APRS email list ( ) and see if someone at a higher level can apply more pressure.? This is ultimately not a Direwolf issue and people here won't be able to do much about this.

?? - Create a iptables firewall filter to BLOCK any outbound contact with these two APRS-IS server IPs and then see what Direwolf does in terms of possibly retrying and possibly connecting to one of the other NON-BLOCKED IPs.? If that doesn't work, I would argue that Direwolf should be enhanced here but that might take some time.?

?? - Setup and use a local DNS server that will resolve this noam.aprs2.net address with whatever IPs he does or doesn't want.? This new DNS zone file will need to be updated and reloaded on a regular basis to have the newest set of APRS-IS host IPs that might be coming/going to the network.

?? - Try some iptables tricks to locally NAT (aka redirect) outgoing traffic away from these bad APRS-IS IP addresses to a good IP APRS-IS but that's rather gross


I'm sure other crafty ideas can be offered up from other smart people on the list but I still think option #1 above is the *right* way to solve it as I'm sure other people are having this issue but they don't know it.

I would guess that the versions of javAPRSSrvr these two servers are running (4.0.7b10 and 4.0.8b07) may not handle the range filter properly, in which case the server owners may want to update to a more modern version.

Hi Arnold,
?
What server-side filter are you setting in your configuration?
I see both those T2 servers are running javAPRSSrvr, but there are other Direwolf v1.7 clients connected that are setting server-side filters so doesn't immediately appear to be an incompatibility between DW 1.7 and? javAPRSSrvr.
?
If you want to avoid connecting to those two servers, you could drop the host routes to them on your igate which would cause connection attempts to fail and the next server in the pool would then be tried.
