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.

How is running transmission as a dedicated user more secure? (lemmy.ml)

I noticed Debian does this by default and Arch wiki recommends is citing improved security and upstream.

I don't get why that's more secure. Is this assuming torrents might be infected and aims to limit what a virus may access to the dedicated user's home directory (/var/lib/transmission-daemon on Debian)?

@CasualTee @Quail4789 With torrent you are specifying the filename when you start the torrent, or at least I am. Thus any data can only go into that file. Usually when you use torrents the way I do, primarily for downloading distros, occasionally source code, an md5sum is provided. Thus before you use the downloaded data you do an md5sum on it and check it against the value it is provided. If it's not the same you remove the file and start over, if it is you know you didn't get any additional data.
