New Stations Added

Hi all

Pi3 is supported, and as mentioned the sd card does not latch on a pi3

Can you connect a keyboard and monitor to see if we get any diagnostics?
Alternatively, you can connect over ssh or shellinabox, this should be documented in the guide

Also, it can take upto 10 mins after book ing before the ports are active

Thx
Lee

Interesting - so it might not be the SD socket...didn't know a Pi3 SD card socket was different (not an improvement in my view!)

Yes, I tried the IP address as shown on the router, and the host name - which is ognpaw (NOT ognpaw.local)

I think I mentioned in my earlier post I had tried http://192.168.1.67:8080, http://192.168.1.67:8081 and http://192.168.1.67:8082
using Chrome and nothing, and tried to telnet to these ports and also nothing. I CAN ping the host name and IP address so they are
correct?

Think as Lee suggests I'll try and find an HDMI monitor and keyboard/mouse and see if it is booting up, if the card socket functionality is as described it is perhaps not faulty

Hi Chris,
How did you log in to perform the initial configuration ?
you must have used either 'ssh' or 'shellinabox' - is that correct ?

If you managed to use either of these methods to get a login shell, then you should be able to dump the diagnostics from the OGN processes, so assuming you are logged into the PI, can you try the following

$ telnet localhost 50001

This should provide the diagnostics from the OGN decoder which connects to the OGN APRS Servers, this is a pre-requisite to anything running TBH

Thx

Hi Lee

I loaded and configured the software using Shellinabox at Wilmcote and tested the unit which was working here but obviously reporting as at Dunkeswell.

[Chris Parsons]

Hello Lee and Keith

Not sure if Mike told you but we are 'guests' on the network infrastructure of the flying school so I am trying to keep the disturbance
to a minimum?

We (Mike, Brian and myself) have had a few weekends climbing around on the roof, and installing CAT5 cable inside - the OGN PAW Bridge is
15m from the network router, which had no spare ports, so we had put a 4 port hub on the router to give us the capacity. Fortunately the flying
office was not too busy because of the poor weather - the few pilots that came in were very interested in what we were doing, so there was a bit of promotion going on too

I have a feeling when I connect this at home and give it enough time to settle down and connect, everything will be good (ever the optimist!), while I did see the 10 minute connection time in the documentation I am now not convinced that perhaps we left it alone for long enough to connect fully?

One thing that has just occurred to me...I can attach my PAW antenna for the transmissions but don't have the incoming USB feed from the OGN antenna, will this still show up as active on the map?

We have seen that it did briefly connect at around the time we stopped, and decided the SD card was not fitting properly.

At least at home I have the ability to carry out some further testing if I need to. Very interested in your remote 'radar' interface - let me know if you want a guinea pig, I have one or two Pi's I could experiment on, and perhaps offer this to the flying school as a thank you?

Might be worth mentioning the SD card behaviour/change in the docs?

I'll keep you posted

Chris

[Chris Parsons]

Got the OGN PAW Bridge running at home, and it looks to be working - while I appreciate there will be no OGN
traffic (no antenna attached) I do have a PAW antenna attached and wondered why the visibility hasn't updated
on the range map? Or does it update when it picks up traffic?

I have had a look for EGTU on the Aprs servers and cannot see it anywhere - do I need to do some port forwarding
on my router?

I have left the config file alone, the position of the station is actually a bit out but nothing significant but thought it worth
taking a backup, interesting stuff.

Before I drive back up to the airfield and reinstall it, it would be good to know it is connecting and talking so I know any issues
are then with the airfield network?

Regards

Chris

Hi Chris

Can your u look at the http ports we mentioned before
8080
8081
8082

8082 should report your pilotaware as received

Also if you are connected via ssh

telnet localhost 50000
telnet localhost 50001
telnet localhost 50002

Thx
Lee

Guys,

Just looked at Glidertracker - nothing showing, so switched to 'Spot the Gliders' and PWEGTU was showing at Dunkeswell - albeit red, but that's probably because there is no traffic at this time of night - 1015pm. Checked back again a few minutes ago at 1025 and EGTU is visible but PWEGTU has disappeared again. I take it you are testing Chris?

Peter

PWEGTU back again at 23.00

[Admin]

Hi Peter

The definitive method to detect if a station is connected, is to look at the APRS servers page
Spot the gliders will only show either EGTU or PWEGTU I think

Thx
Lee

[Chris Parsons]

I left it running all night - from around 8.00pm so I am not sure about why it was dropping in and out, but think the next step in to put it back at the airfield and see if the Aprs servers still see the station using the airfield network?

I have established that I can open http://<ip>:8080, http://<ip>:8081 and http://<ip>:8082 from home, while I couldn't get anything from the airfield

Keith, you are correct about being little difference between you running it on your network and me running it on my network but I take small steps - for instance I cannot see the Aprs servers from the office network because port 14501 is not open? Not sure if there are any restrictions on the airfield router for instance?

Don't think this will be a problem as the station has been seen once, on Sunday when it was connected at Dunkeswell so it must be visible at least part of the time (ie the relevant ports are open)

Regards

Chris

Hi Chris/Lee,

Yes, I realise that checking the server listing is the definitive test. Just thought it might help Chris to know the station had been visible on the net.

Chris might not be aware that the OGN net (spot the gliders and ognrange) has been a bit ‘shaky’ for several months now and often shows stations as being ‘down’ (red) when they actually aren’t, so the fact that a Station is showing red (or isn’t showing at all) doesn’t necessarily mean the unit isn’t working.

As you say Lee, the only reliable way to check is to look for the APRS messages on port 8081 and look for the station on the APRS servers.

Chris, if you are interested, there is lots of useful additional info available on the OGN Forum....

https://groups.google.com/forum/m/#!forum/openglidernetwork

....(though some of it does get a bit ‘highbrow’). You need to sign up first via the OGN wiki page....

http://wiki.glidernet.org/subscribing

I’m sure you’ll get to the bottom of it shortly. Looking at UKNHL on www.flarmrange.onglide.com , you should get really good coverage from Dunkeswell, so well worth the effort.

Best Regards

Peter

Ok, I am home and have switched the PSU to one of the new Pi3 2.5amp PSU's

I have attached a centre fed dipole to my PAW and left the end fed dipole on the OGN PAW Bridge
but my PAW has not (yet) appeared on 192.168.1.24:8082

I have noticed that the 'connected to' info in the aprs section on 192.168.1.24:8081 changes periodically,
I guess this is the server losing connection and the bridge getting reconnected to a different one?

You wanted me to capture some diagnostics, I'll look out the post and do that shortly?

Chris

 

[Admin]

Hi Chris

just to clarify, this is completely unrelated to the bridge, what we are seeing here is a networking problem, the OGN decoder is connecting / disconnecting, and from our recent email exchange sounds suspiciously like an NTP issue.

A quick check would be to print the current date from a your secure shell login
$ date

Thx
Lee

EGBS (Shobdon) OGN-R installed last Friday, though the antennas will have to be relocated on the VCR at the request of the senior AFISO.

The system was set up by Keith Vinning off site (thanks Keith) and just appeared to work once powered up. Owing to the nature of the local computer network I was unable to determine an IP address for the ognpaw unit, so no diagnostics were possible at the time. Fortunately PWEGBS showed up on glidertracker.org  and I was able to see evidence of some Flarm contact. Yesterday saw some PAW contacts also but checking on ognrange.onglide.com plus flarmrange.onglide.com I see the Flarm track of last Friday but switching to see PWEGBS the site places it in the Atlantic Ocean south of Gambia*! Checking the aprs servers I can see EGBS listed but NOT PWEGBS. Strange that glidertracker was showing PAW tracks. Any thoughts where the problem lies?

Edit: * zero lat/ lon so no GPS location in some database.

[Mike Mold]

It looks like PWEGTU is now working.
