This is a very nicely done little page. Good stuff!

Page name and move[edit]

This page should probably be at FreeBSD jail, since it isn't being used a proper noun anywhere but the title. Unfortunately, it requires an admin to move since some anon created an article at that link... --Gwern (contribs) 03:33, 13 October 2006 (UTC)

I noticed the same thing. I fixed it. - furrykef (Talk at me) 03:28, 23 December 2006 (UTC)

DragonFlyBSD also supports the Jails. And the DragonFly jail is yet better as the FreeBSD implementation. Why is this not mentioned in the article? —Preceding unsigned comment added by (talk) 18:58, 19 September 2008 (UTC)

Other OSes with this feature?[edit]

Besides a *BSD variant or two, I haven't seen this feature in other *NIXes. Anyone have an idea how one could do this in Linux or Mac OS X? I think it'd be neat to allow an app (e.g. a webserver) to jail itself for added security.Twir (talk) 16:50, 5 April 2009 (UTC)

Solaris Zones are a similar concept, and I think Solaris Containers as well. Stuff like OpenVZ, Virtuozzo Containers, and Sandboxie are also similar. (talk) 22:48, 21 January 2015 (UTC)


  • This article is clearly written in a promotional tone.Jasper Deng (talk) 01:40, 26 June 2011 (UTC)
  • Please note that the FreeBSD and jails discussed here are not paid products of any company or individual. But are opensource free software and done on a volunteer basis. Therefor the promotion of such is a mute point. It may even urge others to add the functionality to their own flavor of *nixes.
    • Still, it musn't be overly promotional and neutral point of view is something that applies regardless.Jasper Deng (talk) 05:00, 16 July 2011 (UTC)
      • An enthusiastic page with legitimate content is better than no page at all. This kind of esoteric technology rarely generates enough job listings to cultivate an authoritative voice bereft of enthusiasm. If there were more to promote, the problem would solve itself. (BTW s/mute/moot. This error is becoming so common it could enter the language.) — MaxEnt 18:08, 29 May 2013 (UTC)

Constricted or verboten?[edit]

Additionally, interaction between processes that are not running in the same jail is restricted.

  • Kept within certain limits; limited: on a restricted diet.
  • Excluding or unavailable to certain groups: a restricted area.
  • Of, relating to, or being information available only to authorized persons.

So which is it? — MaxEnt 17:59, 29 May 2013 (UTC)

They can still communicate over TCP and over socket files (if their file systems overlap). Shared memory is also not separated (and thus disabled by default for security reasons). (talk) 22:41, 21 January 2015 (UTC)
