When I setup this server, I was going to use FreeBSD but a coworker told me that OpenBSD touted their strong stance on security. Their website boldly claims that there hasn’t been a security hole in their “default configuration” in something like eight years. So I gave it a try and installed it. I don’t know if sshd is part of the default configuration but it had SSH1 enabled by default. I don’t think Fedora or Mandrake or any other Linux allows SSH1 by default.
I claim that sshd is part of their default config because all the install asked me was “Would you like to install sshd? [Y/n]“ So I instantly distrusted OpenBSD from that point on because their claim seemed outlandish.
Not only that, but the default installation didn’t even install the ports service (think urpmi, yum, etc). That’s how their tutorial talked about installing all services. I spent forever trying to find dependencies for all the things I wanted to install and just gave up.
So, even if they are the most secure OS in the world, they are probably the least user friendly.
