Ah very nice, good to hear they addressed that. It was the only real deciding factor last time I moved my mail around ~2 yrs ago

Fastmail. It’s been around forever and it just works. And they don’t do anything weird with SMTP/IMAP.

mailbox dot org is also pretty good, but I wasn’t a fan of their 2FA implementation.

It’s fine. RAID is not a backup. I’ve been running simple mirrors for many years and never lost data because I have multiple backups. Focus on offsite and resilient backups, not how many drives can fail in your primary storage device.

Not sure how to do that in docker, I’ve run mine as a plain old PHP-FPM site for years and years. It might be something that can be tweaked using config files or environment variables, or might require building a custom image.

ClamAV is slow and doesn’t catch the nastiest of malware. Its entire approach is stuck in 2008. It’s better than nothing for screening emails, but for a private file store it won’t help much considering that you’ll already have the files on your system somewhere. And most importantly, it slows down file uploads 10x and increases CPU load substantially. The only good reason to use ClamAV for nextcloud is if you will be sued if you don’t!

It needs some tweaks to be snappy. The defaults are really bad.

• change database from SQLite to a proper database like MySQL or Postgres, and configure the database server to use your memory fully
• increase the PHP memory limit from the default (128M on many distros) to >1G, the more the better
• install APCu in-memory cache for PHP
• add Redis as additional cache
• turn off the antivirus extension, if installed (ClamAV is useless)
• use http/2 on Apache/nginx to increase performance with multiple connections

This was my setup from about four years ago. Other than moving suricata elsewhere, it’s largely the same. Worth a shot if it’s something you’re into!

OpenBSD is also great, I’m just more familiar with the Linux tools. All the required tools are in the base image, and they have a great official guide:

Yep. Firewall, routing, dhcp, dns, everything you’d expect from a gateway device. Plain Debian (or really any distro) can do it all. With a 1gbps bi-directional connection fully saturated it will run at about 10% cpu on my very crappy low power Celeron CPU.

Plus, there’s no web UI full of janky and insecure CGI scripts to exploit, and software updates are forever (well, until x64 is deprecated, so basically forever).

IPtables on Debian because I like my life to be boring and unchanging.

For about a year I was running a full out of band IPS on my network. My core switch was set up with port mirroring to spit out a copy of all traffic on one port so that my Suricata server could analyze it. Then, this was fed into ElasticSearch and a bunch of big data crap looked for anomalies.

It was cool. Basically useless because all it did was complain about the same IP crawler bots as my nginx logs. But fun to setup and ultimately good for my career lol.

I mean it is possible to run your own authoritative nameservers on a server you own with a static IP. It’s a pretty irresponsible thing to self host, but it is possible :)

You can use pretty much any camera with ZoneMinder as long as it supports ONVIF or RTSP and has the right connectivity and power inputs for you. I did something similar with some cheap TP-link cameras with pretty good results. With motion activated recording, I have just shy of 12 month of recordings stored on a 500G SSD.

SPAN port on the switch, send it all into a server running Suricata which can analyze, classify, and log all the traffic. Don’t run it in IPS mode online unless you’re willing to suffer a little…

Could always whitebox it with Debian, nftables, dnsmasq, hostapd, etc. on an old mini PC if it has two NICs…

5 yrs for free is LTS, 10 for “Pro” enterprise subscription ($$$).

It’s pretty good. I understand and somewhat agree with the concerns about concentrating the web around one company, but tunnels is simply a great product. So convenient for running services behind CGNAT or dynamic IP without good port forwarding options, and it’s just set and forget. If there was an alternative that good I’d use it.

If you’re strong willed and stubborn, Zoneminder will work fine. It takes a lot of tinkering to get everything to work correctly, but it does work decently.

Not strictly RSTP, but the “zmninja” app works with a Zoneminder server, which can record and manage RSTP/ONVIF cameras. I would really recommend some sort of NVR (like Zoneminder) if you have cameras since there’s a low probability you’ll be able to watch them live all the time.

Yep, banning scanners with ipset lists is a great solution. I use a slightly convoluted method to perma-ban abusers, but fail2ban also works great.

Best advice I can give is to make sure the default virtualhost on nginx/apache just sends a 404 to all requests to your IP, and only serve the apps you want when they’re accessed by the correct hostname. The vast majority of spammy scanners are just hitting all public IPs, so as long as you don’t tell them what you’re hosting you’ll be alright.

Then, I’d advise having some sort of basic web application firewall (WAF). Modsecurity is a common one, NAXSI is another. These take some time to set up, but are quite good at absorbing attempted attacks.

Generally speaking, yes, but things can get a little weird when you’re dealing with an abstraction like docker.
