Changing port 8080 issues

FlightAware ADS-B Flight Tracking
1

On one of my feeds I change the /etc/lighttpd/conf-enabled/89-dump1090-fa.conf file from 8080 to 8282 so I can forward that port.

'# Listen on port 8080 and serve the map there, too.
$SERVER[“socket”] == “:8282” {
alias.url += (
“/data/” => “/run/dump1090-fa/”,
“/” => “/usr/share/dump1090-fa/html/”

It has worked until recently (possibly 3.7.2 upgrade?). Now if I do this it does something to the map display. IE nothing is displayed, no flights no range rings nothing. If I leave it set to 8282 but check localIP:8080 the map displays but no flights or data.

This is what the map looks like with 8282 set.

Changing the file back to 8080 fixes the issue.

Ctrl-F5 maybe?

I don’t see any changes in regards to that configuration or any problems.
You are restarting lighttpd after changing the configuration i assume?

3

Yeah, did a reboot on the PI just to make sure and ctrl+F5 to clear the cache on the viewing browser.

What I find odd is that :8080 would still show the map when :8282 is mapped in the file. Wouldn’t that indicate that 8080 is still configured somewhere?

I referenced a post that you posted in when I first did this and it was working then.

I initially did this because of the two feeds running from two different PIs. Primary is running 8080 out of the box so I moved the secondary over to 8282 so I could see them both while not local.

4

Maybe you are confusing your two RPis?

Let’s check this:

grep -r /etc/lighttpd/conf-enabled -e socket

Does the log show any problems?
sudo journalctl -eu lighttpd

5

The grep search has no output at all and the log is empty.

Side note: graphs works with or without :8282 when 8282 is configured.

6

Yeah, bad command:

grep -e socket /etc/lighttpd/conf-enabled/*

The log really should have something in it.

Sep 30 21:30:06 pi systemd[1]: Starting Lighttpd Daemon...
Sep 30 21:30:06 pi systemd[1]: Started Lighttpd Daemon.

Anyway if the webserver is running, then the logs won’t show anything.
That’s just the place to check when the server isn’t running.

Also let’s just see the complete config file with the modified port you’ve tried:

cat /etc/lighttpd/conf-enabled/89-dump1090-fa.conf

Please put ``` on their own line around the text, so the formatting is proper.
If you can’t find the ` on your keyboard, you can just copy this line:
```

)

  alias.url += (

    "/" => "/usr/share/dump1090-fa/html/"
  )
}

# Add CORS header
server.modules += ( "mod_setenv" )
$HTTP["url"] =~ "^/dump1090-fa/data/.*\.json$" {
  setenv.add-response-header = ( "Access-Control-Allow-Origin" => "*" )
8

Did you modify /etc/lighttpd/lighttpd.conf ?

I don’t see why it wouldn’t work.
Is /dump1090-fa working with the new configuration (on port 80)?

9

The only bits I’ve changed are the set gain in the title bar and graphs. Then the 8282 port change.

10

You should check what the browser is actually seeing as a first step - look at e.g. the developer tools window in chrome (f12), network tab, reload the page, see if it’s getting errors.

11

There are some errors.

8282fail
8282fail1001×738 133 KB

12

And http://192.168.25.82/dump1090-fa works?
Or does it have the same errors?

13

Yes http://192.168.25.82/dump1090-fa and http://192.168.25.82:8282/dump1090-fa/ work perfectly.

14

Do they work after Ctrl-F5?

Get the impression the other pages only work because the browser has them cached.

15

They do work after reload and they work after clearing cache in chrome settings, history, cache and cookies.

16

please show the full network trace; it looks like openlayers / jquery aren’t loading successfully, but I can’t tell why because those requests are off the top of your screenshot

The 8282 jquery/openlayers javascript is way too small. What do you get if you directly fetch e.g. jquery-3.0.0.min.js?

19

From the 8282 there is nothing.

ip:8282/dump-fa I get data 86407 chars / starting with this but had to delete some to post.
