OP25 OP25 Errors

[krutzy]

My OP25 installation is running ok but I have noticed some broken transmissions. So I went to look at the rx.py log and I am getting these repeater errors. Any idea what is causing these?

Thank you,
Kevin

Boatbod or nonBoatbod? Any browser extensions?

 

[krutzy]

No extentions. Orginally boatbod but replaced with osmocom.

 

[NebraskaCoder]

Ah, ok. I can't vouch for the new interface code. Sorry. If it was boatbod, then that would have been some sort of extension messing it up, but if it is Max, I'm unsure.

Thanks for this report - it initially appears to be one we haven't seen before - is the error repeatable and if so, how often are the incidents and are there any other symptoms? Which web client (browser software/version) are you running when the error occurs?

There are actually two errors - the initial parsing error and then secondarily a crash in the python code. I will push a probable fix for the second error later today...

Kevin

please post your rx.py command line. If you're running multi_rx - please post that command line as well as a copy of your configuration json file.

Thx

Max

Max,

First, this may throw a curveball but I run Opera browser v78. There aren't many extensions but it has some ad and tracker blocking built in. Just fireshot and lastpass. It seems to be repeatable but if it based on screens I am not sure. I can always use Firefox. I can always try some different things.

My start line is:
./rx.py --nocrypt --args rtl -N LNA:47 -S 57600 -o 25000 -d 300 -q 1 -2 -T kutrunk.tsv -w -u 23456 -P constellation -l http:0.0.0.0:8080 -V 2> stderr.2

It is the boatbod version so some of this is for liquidsoap. (I think).

Thank you, let me know what I can try.

Kevin

-l http:0.0.0.0:8080

OK thanks for posting this info.

This shows the web service on port 8080 is accessible to any machine on the network.

By any chance, is it also publicly accessible?

Max

 

[krutzy]

Yes but not advertised. I just wanted to be able to access when not home.

 

[NebraskaCoder]

Sounds like someone is trying to hack you. Even if you do t advertise it, it is normally picked up on the internet within 30 minutes.

Fix pushed to osmocom repo master for the tributary python crash in http server. Should need only to update using "git pull" as no rebuild is req.

Max,

I have let it run for a while and gone to different screens. Everything is a lot cleaner now!

Thanks for the fix

Kevin
