I'm not sure if those are still issues (e.g. I don't use NFS), but that may be why the values have been set that way by default. I hope that thread helps!

Depends on how the systems is used, to some extent. You probably won't notice it as long as it doesn't get ridiculously large. I realize that statement is a circular definition, but an accurate answer would, well, depend on how the system is used. > What will be an acceptable value for NGROUPS_MAX? > I know this number is set to 32 in suse linux I suspect doubling it would be fine, but trying it is the best way to know. > I know that ACL is a better way but i wont use it until it's stable under 5.x > freebsd and that 5.x is recomended for production issues. If your application really requires this sort of thing, 5.x might be more stable for your application than 4.x. Or maybe you should describe how you're getting to need so many groups, and see if someone can suggest a better way without the groups... > About how doing that change... > Is it just about changing the value and reboot the machine or there is some > recompilation matter linked to that change? You have to rebuild everything that uses it, of course. I'd recommend a full system rebuild. http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html -- Lowell Gilbert, embedded/networking software engineer, Boston area: resume/CV at http://be-well.ilk.org:8088/~lowell/resume/ username/password "public" ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
NGROUPS_MAX
Hi, i'm jonathan and i'm running a freebsd 4.8 box. i wish to increase the value of NGROUPS_MAX into /usr/src/sys/sys/syslimits.h. I'd like to know how increasing that number to permit users from /etc/passwd to be member of more than 16 groups will affect system performances. What will be an acceptable value for NGROUPS_MAX? I know this number is set to 32 in suse linux I know that ACL is a better way but i wont use it until it's stable under 5.x freebsd and that 5.x is recomended for production issues. About how doing that change... Is it just about changing the value and reboot the machine or there is some recompilation matter linked to that change? Any help will be greatly appreciated! I'm new to this list... everybody keep on that good work ;) ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Change NGROUPS_MAX
Hi All, Does anybody know how to safely change NGROUPS_MAX under Freebsd 4.7 Release? The problem is that I need to make one user account to be joined to more then 16 groups. Sincerely, Artur.
