Hello Our's FreeBSD have nice possibility of hiding process informations of other users just by setting kern.ps_showallprocs=0. But there is one bad thing about it. For what we using it, when anybody can read all informations from /proc filesystem. And, as everybody knows, this filesystem contain information on ALL processes in system. So I was trying to protect this information by permissions manipulations but without possitive results. The only workaround is to umnount /proc and hash it in /etc/fstab, but I think it's not good idea to resolve this in only in that way. If somebody has some good solution to this problem: I'am ready to read about it. I working on FreeBSD 4.6.2-RELEASE and 4.7-RC. -- Nomad [%% When you dance with the devil %%] [%% the devil don't change. %%] [%% The devil changes you. %%] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
