Antivirus would probably be clamav.
As for policy, selinux would be my first Google.
Software allow lists I’m only going to mention system wide since stopping user space installs or chroots would be your software detection tool that I would be clueless on. System wide I’d look at sudo where you can control exactly what root level commands different users/groups can run.
GitHub has the option of emailing you on releases etc. by email.
install Debian the way you want up through the apps you need. Then it off and use it as a clone to copy for all your setups as needed.
Brother does sell laser printers but they cost a good bit more. What media do they actually print? That would help a lot in trying to give advice.
I’ve been using an onn brand puck that was cheap as dirt and been working for hdmi to my tv. Honestly if there’s a Walmart nearby I’d recommend going that route if cheap and occasional usage is the goal.
Glad we got to the root issue! As others have said this is a learning process and you picked one of the more complicated ones to start with. Once this is done e everything else will start to feel much easier!
If you are on the raspberry pi with a physical screen/keyboard and mouse you can also try accessing with the ip address "localhost:80" and see if there's a connection that way as well.
We can get the port list another way. From the terminal on the raspberry pi run the command "nmap localhost". Let us know what that shows, but I would expect to see either 80, 443, or both.
As a side note, if you did not give the nextcloud container a certificate when you made it, you cannot use https:// on the browser, as it has no way to talk using that security mechanism. It is only capable in that case of using http:// and port 80. You will need to disable forced https to access the site (this is fine on the local network if every device is trusted, and only encrypted vpn service in like zerotier is used imo). This might be your problem here, especially if you are seeing both ports listed as open on the pi.
You would be given a safety risk warning page by your browser if you did the self signed certificate that you’d need to tell it to connect anyway, so that likely isn’t the issue. Looking at ports, how are you trying to connect to the server? If you did not assign a certificate at all, you would want to use port 80, port 443 if you did install a certificate.
For instance, my Nextcloud is on ip 192.168.50.30 With that in mind I would be using:
No certificate: http://192.168.50.30:80 Certificate: https://192.168.50.30:443
Does this look like what you are typing in?
As two additional questions, what is the output of “docker container ls” typed into the terminal? And what operating system did you install on the pi, was it raspbian?
At a glance your first issue is finding the correct ip address, you should only have one local ip address to access it with (inside your home network).
To find your local ip, type “ip a” into the terminal, and look for the address under “eth0“ for a wired connection, or “wlan0” for wireless. This will allow you to connect using the ip and port while on your home network to test the connection and make sure it works right.
After that, I highly recommend the vpn option, it will simplify connecting to it while not at home without creating security issues like setting it up with a domain. I personally use zerotier, that guide will help you get it set up on the raspberry pi. Not the last bit about a “managed ip.” That will be the address to tell your phone to connect too once you have the vpn set up on the phone as well.
This has to do with encryption protocols. Offhand my assumption is either they are trying to be extra cautious as the rules are incredibly complex, or they have a different algorithm included by default that would be subject to those rules.
