hey so im stuck on this, what does this mean?

I saw the online phantom sdrs, I wanna do something like this with just a RTLSDR V4, MLA-30+ and a Ubuntu laptop, how would I do that? I tried the phantomsdr GitHub thing but it looks really bad (the site) and is pretty much not working, would be nice to have your help.
I'm referring mostly to it looking like the http://websdr.lumpkinschools.com/ WebSDR

My list is:

This is much less than the number 91 in the official list.

Is it not possible to make some cron command that would restart the official list at least once every night until the bug with filling the list with non-existent servers is solved?

Something similar to this:

#-- RX888MK2 -----------------
#
@reboot /bin/bash -lc 'cd /home/websdr/PhantomSDR-Plus/ && ./start-rx888mk2.sh' && sleep 150 && intel_backlight 0

Anyone an idea how we write a logfile of chat-posters with IP-address so they can be banned via iptables?

Some people keep posting nasty stuff, I want to ban them from using the websdr in total.

How do we write a log with IP via chat.cpp? Anyone?

Seems Steven his server has problems again.

If this keeps happening, we will start a new list and host it on the forum-webserver.

We have reported problems too many times to keep on using this list.

It should not happen. My testing-server is turned off and also still listed.

Looks to me the webpage isn't updated (again)

Hi,
I currently DO NOT have four PhantomSDRs.
I don't know why they are showing up four times in the sdr list.

I added that chatbox change, did an npm build and restarted the sdr.
Currently I have register_online=false in config-rx888 and my sdr is visible in the list.

I think it's a bug in the list.
