Has anyone run across the authentication error messages below?

root@AI6BX-DMR:~# tail -f /var/log/dmrlink/dmrlink.log

I have a similar error.
AuthError: IPSC packet failed authentication. Type 80:

any ideas any one?

Can you post the entire log line and a few above and below, please, and something about the setup of your system – what's a master, what's a peer... so that I can assess what device is sending a packet, and at what position in the stream it is.

You guys also need to realize that not everything that gets logged at the ERROR level means something is broken.

I have a Motrola xpr 8300 as a master. dmrlink is the peer. the configuration is IPSC_Bridge to HB_Bridge to HBlink3. 

we get connection and audio from the server to the repeater to the radios. but when you go radio to repeater to IPSC_Bridge. IPSC_Bridge puts out that error and nothing gets sent to HB_Bridge.

Thanks for the help.

Yep – that’s what it looks like – Group voice packets from the repeater failing authentication. How long was the transmission, roughly?

The transmission lengths would vary between a couple seconds to 20++ seconds. with same results.

Always the same number of authentication error packets regardless of the transmission length?

no there will be more depending on length. scrolling about the same speed as import_datagrammReceived when it is repeating a transmission from HB_Bridge.

Looks like all of the packets from the incoming voice stream are failing as authentication. I’d never seen a case like that previously, where the link establishment ones pass, but the voice stream doesn’t.

I don’t have even a single MOTOTRBO repeater anymore. When I sold the last one was when I stopped developing DMRlink.

Could be some fluke with the password, some extra Motorola gratuitous feature enabled, or if you’re running the latest firmware, I suppose they might have changed IPSC somehow.

Weird. Well we're going to swap the machine for a known good one. Going to do more testing in the home lab than the repeater site.

IPSC was reverse engineered. There’s way more I don’t know about it than what I do. Mostly I figured it out by brute force, and a few folks stepped up in the early days with nuggets of info that helped. There’s going to be a lot about it we don’t ever know.

I’d recommend simply trying to change the password, flip the master/peer relationship, strip down to the basics in the subscribers and if applicable, the repeater (no enhanced channel access, tx interrupt, etc) and start from there.

Richard,

Did you make any progress on solving this? I took a bit of a break on my project over the holidays and am stepping back in. I noticed Cort's comment about a potential firmware glitch so took a look at several of my 8300 machines as I have firmware ranging from 2.03 to 2.09, one of the latest versions before they jumped to the new CPS system. I do see this on the 2.09 machine and not on the 2.03 version. I may try to drop back on the firmware to see if that resolves the issue on that unit.

It was solved by turning off authentication. The machine connects to a raspberry pi within the network that converts it to mmdvm to the main hblink server. So the authentication was a little redundant.

In the future may play with it again but right now everything is working.
