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.

could you explain the difference between using these 2 commands to open a port? iptables and ufw (lemmy.ml)

commands are:

iptables -I INPUT -p tcp --dport 3389 -j ACCEPT > to open only that tcp port

sudo ufw enable transmission > to open the whole program

being a newbie I'd say it's safer to only open a determined port with iptables. What do you think?

ufw or firewalld have presets and will automatically open the right ports and traffic types.

Also these are different programs.
