From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

@Shdwdrgn on Linux, the firewall with zero custom rules always allowed everything. did that change in very recent kernels? if that's the case, I'd expect a lot of lost acces to remote servers
Most of my experience is with iptables, but yeah, I think until you start adding rules nothing is implicitly denied? Once you enable a couple of initial rules then you should have good blocking from the outside while allowing internal traffic to connect freely. It doesn't get in your way until you start using it, but then it doesn't take much to get it going.
