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.

Has anyone used nsjail? Any thoughts? (lemy.lol)

I recently learned about nsjail, a utility to sandbox applications or provide workload isolation.

It seems to be lighter weight than firejail and possibly better suited for server applications.

Has anyone used this? What's your experience with it? I'm curious about using it for my web server applications as an additional layer of Dr hotty.

Thanks a lot for taking the time to explain.

I did notice CTF on the description so I imagine "escaping" it is "harder" than with containers. I recently participated to SplinterCon which included a "block-a-thon" (cf day 2 of https://splintercon.net/brussels/ ) to try to escape a limited environment, approximately simulating the limited Internet access of some political regime. It might be interesting in that context too.

Could also be interesting then to distinguish which defaults are changed compared to Docker ones or examples for which nsjail is currently preferred.
