Just checked one more time that emails from my server are accepted by Gmail. What am I doing wrong?
the list of the daemons running in docker-mailserver
Awful. Who heeds both rspamd and spamassassin simultaneously? fetchmail and getmail6? More than a half of these components are not required to get a working mail server. But I agree that setting up the another half is rather complicated. So I’m planning to give a try to mox when I’ll need to set up a new mail server.
Why not OpenWrt?
Yes, you select projects that you participate in by yourself.
You may install BOINC and contribute to scientific computations.
The best way is to disable password login and use SSH keys only. Any further steps are not required, but you may additionally install fail2ban or sshguard.
It asks for a path to a root directory of a bootstraped container. You can create it with debootstrap, rinse, pacstrap, alpine-chroot-install, virt-bootstrap etc.
virt-manager is able to work wit lxc. Add a new connection of type Libvirt-LXC.
Yes, you can.
Do you really need OPNsense? Buying a OpenWrt capable router would save your money, place and silence.
Well, I don’t use proxmox, however docker coexists with libvirt and other virtualization systems. If there are overlapping networks that docker ant proxmox attempt to manage, they are configurable.
Snapshotting in docker is as easy as docker commit. After that you can back it up with docker save. Then move to another host, but not without downtime.
However normally you need to backup/move only volumes attached to containers. If that’s not the way how you like to organize your services, you likely don’t need docker.
What’s the purpose of running container in a container? Why not install docker on your host machine?
I meant software RAID of course. Hardware RAIDs just cause headacehes, but fake RAIDs that are built into motherboards are a real nightmare.
Building RAID on top of SSDs is an answer.
With fail2ban single bot behind a NAT can make the site unaccessible for all users behind that NAT.
Full code audit is very time consuming. It’s impossible to audit all software someone uses. However if I know nothing about project, I do a short look at the code to understand if it follows best practices or not and make some assumptions about the code quality. The problem is that I can’t do this if I’m unfamiliar with the programming language the project is written in, so in most cases I try to avoid such projects.
