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.

Is there an advantage of using doas over sudo (thelemmy.club)

I see people talking about doas saying it's just like sudo but with less features. I'm just wondering if there is any situation where you should use doas or if it's just personal preference.

How is it more secure?

[–] youRFate@feddit.de 9 points 8 months ago

Afaik much smaller code base and as such easier to audit.

I think it's because sudo only requires a password the first time on each shell.

[–] bleistift2@feddit.de 8 points 8 months ago (2 children)

sudo maintains ‘sudo state’ for 15 minutes. After that you need to enter the password again.

15 minutes that's good to know thanks.

[–] taladar@sh.itjust.works 3 points 8 months ago

It is a configurable value so don't rely on it being 15 minutes everywhere.

TIL, thanks for this info

It's entirely configurable but I think by default sudo will "cache" your authentication for a period of time so multiple commands in the same session only need the password entered once. You can even configure sudo to not need a password for certain commands (although obviously you need to be careful you're not opening a hole in your security).

doas is likewise configurable; though the mechanism that keeps track of the timeout is different on OpenBSD (where doas originated) & Linux ---- and there used to be some reservations about the latter implementation.
