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?

A big thing the other comments are missing is that just running the iptables rule only works for the current boot. You need something to rerun it every restart

ufw is a front end to make it easier to use them

If you want/need more control, you should look into /etc/iptables/rules.d config files

Edit: or depending on what your distro already has, the firewalld comment makes a lot of sense. E.g. that’s Fedora’s default front end
