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?

Both are fine. Ufw has a set of applications that are defined in terms of what ports they need for convenience. You wouldn't have to know that 3389 is for RDP, you could just allow RDP. Ufw ultimately modifies the iptables, it is just another interface for interacting with it.
