I installed Fedora Server 25 a week or so ago on a small server, sshd was open (with an extremely strong random password) and fully functional at install time. SELinux has caused no issues, I actually chose to install docker in the installer at install-time and it came pre-configured to play nice with SELinux.

Firewalld on the other hand, I'm still figuring out (firewall-cmd is useful, but trying to translate iptables rules -> firewalld is proving harder than I expected)




One of the reasons I like OpenBSD. Linux has a habit of taking well established things and replacing them with incompatible things (firewalld, systemd for example).

I have enough to do, I don't need to throw away years of acquired experience every few releases. It's one thing if the replacements are clearly better, but for me they just seem to be new, different ways to do the same things.


I'd argue that (at least in recent years) OpenBSD does a lot of replacing as well, but I happen to like their direction, where the replacements are simpler rather than more complex.


firewalld is just a daemon frontend to iptables. The underlying firewall hasn't changed since Linux moved from ipchains to iptables.


Every time I mess with Fedora I have to screw around with selinux trying to figure out how to make ~/.ssh/authorized_keys work. Every time I need to google the stupid magic incantation that makes things work (that normally should "just work") because I can just never remember it.


I have always run SELinux on Fedora/CentOS/RHEL and I don't remember a time where I had issues with authorized_keys. The only thing recently I recall about ssh is that is complains if the files in .ssh are not mode 600.

SELinux has come a long way since RHEL4 days.


I'm not talking about RHEL4. I'm talking recent Fedoras (within the last year or 2). Making a brand new ~/.ssh/authorized_keys file has never worked for me without running restorecon (which is the thing I can never remember).
