dump1090-fa v7.2 - Empty Aircrft Table on Right Side of Skyaware Map on Kali Linux amd64 2022
dump1090-mutability EB_VER - OK
Piaware Installs & Works OK
Visit it in a browser that’s larger than a stamp?
Check for console log errors, standard stuff you should know after testing i don’t know how many obscure configurations

Please do not get wrong impression by screenshots I have posted. These are of the local browser of the Kali in VM.
I have also checked the Skyaware map in my Desktop’s full-sized Firefox & Google Chrome browsers at IP-of-Kali/skyaware/. The results were same, i.e. unpopulated aircraft table.
I have also several times cleared browser cache (Ctrl+Shift+Delete) and reloaded broser (Ctrl+F5), but problem persists in both the Firefox & Google Chrome on my Desktop as well as in VM.
Well then see if any errors are on the dev console (F12).
I just want to point out for general information that Kali Linux was designed to be booted from removable media such as a USB stick or optical drive and used by cybersecurity experts for penetration testing, security auditing, white hat hacking and forensics, particularly in secure environments where the security team isn’t allowed to bring in their own computers or have Internet access. It isn’t intended to be an installed daily-driver Linux distro. As such it may possibly lack some components that come with most normal desktop distros and that are needed to run some end-user software, Kali was only designed to be able to run the security tools that come preinstalled in the OS, not necessarily to be able to run added-on applications.
You’re missing some javascript.

This can happen due to some lighttpd stupidity even when the file exists.
Try http://127.0.0.1/skyaware/formatter.js
You see it in the html folder, so it should load.
My guess: you have lighttpd deflate enabled in the lighttpd config, it makes a mess of things.
lighttpd is completely buggy which is kinda sad.
I mean most of the time it mostly works … but the issues it causes are very spurious and annoying.

Well, try again and see if it loads formatter.js now.
Check the F12 network tab and see what happens with the formatter.js loading.
Found Kali Linux fresh install has apache2 and nginx pre-installed, but both are disabled.
Please note that in Kali Linux, many pre-installed packages are disabled by default.
Also ALL user installed packages are disabled by default and user has to explicitly enable these after installation. I have installed lighttpd alongwith dump1090-fa and had to enable both manually.

Here is the strange part:
Although apache2 is disabled right from writing the iso to hard drive, and lighttpd is installed & enabled, the placeholder page is that of apache2, and not that of lighttpd

Yeah they use the same directory, it doesn’t matter what the default page shows.
Have you right clicked copied the link?
Clicking on the entry before making the screenshot will help providing more info.
Edit: nevermind, found the issue.
@eric1tran might be the the two query strings causing issues?
<script type="text/javascript" src="formatter.js?v=2?v=8.0"></script>
Yes that’s the issue, lighttpd gives a 404 if you add two query strings (which isn’t proper html to be fair.)
(i suppose it might depend on the lighttpd version … and the 404 isn’t present for all versions)
@abcd567 you can change the index.html, remove ?v=2 from that line.

Doh. I’ll get that fixed and committed. Thanks for looking into that guys.
I’ve heard some of the same. Been considering trying out nginx next time I get to SkyAware stuff.

Thank you for the help. It worked.

Removed ?v=2 from this line:
<script type="text/javascript" src="formatter.js?v=2?v=8.0"></script>
So it became:
<script type="text/javascript" src="formatter.js?v=8.0"></script>
Saved file index.html, cleared browser cache and reloaded browser
It is working now

The issue is, even installing it as a dependency will cause issues if something like lighttpd exists.
Would be great if there was a way to just install the binary and then be able to add a service yourself, serve on some other port.
8080 is very crowded btw, who chose that for skyaware?
lighttpd is sadly the defacto standard … so it’s gonna remain the lesser evil to use it unless it becomes completely unusable.
Why not to have an integral web server as part of dump1090-fa binary?
Because then we have to maintain a bunch of web server code.
If there was an actively maintained, easy-to-embed library that could provide this then it’d be another question, but I don’t know of anything that fits at the moment.
