re: procfs in 5.4
hi, i've been wondering long time what's the actual state of procfs in freebsd. yes, i added procfs line to fstab but i do not mount it automatically at system startup. yet i'm still able to use ps(1) unlike the originator of this thread. how come? i believe i've read somewhere that (use of) procfs was dropped or something and freebsd does not use it anymore. if so, i'm asking why and then why did the originator of this thread have problem running ps(1) without procfs mounted? many thanks for clearing this. regards, martin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

It's recommended not to use it unless you need to (at least on systems with untrusted users) because of the history of local security vulnerabilities. i believe i've read somewhere that (use of) procfs was dropped or something and freebsd does not use it anymore. if so, i'm asking why and then why did the originator of this thread have problem running ps(1) without procfs mounted? ps doesn't use (and never did use, afaik) procfs for normal operation. There is one function of ps that needs procfs, which is what the original poster was enquiring about. Kris pgpTegUe2T8ho.pgp Description: PGP signature

On Saturday 21 May 2005 21:56, the author Chris Radlinski contributed to the dialogue on procfs in 5.4: I'm running 5.4 Release. Whenever I run 'ps -ef' I get this message: ps: Process environment requires procfs(5) My kernel config contains these two lines: options PROCFS # Process filesystem (requires PSEUDOFS) options PSEUDOFS# Pseudo-filesystem framework I should have procfs. However, my /proc directory is empty. What gives? This can be accomplished by adding the following line to your /etc/fstab file: linprocfs /compat/linux/proc linprocfs rw 0 0 and then, as root, executing the commands: kldload linprocfs mount /compat/linux/proc -- 40 yrs navigating and computing in blue waters.

No, unless you run the one or two applications that require it. If I disable it will I get any improvement in system performance in terms of speed ? No. It is better for security on a multi-user system though since procfs has had a lot of security vulnerabilities over time, so there may be more. Kris pgpZfegvp0NCr.pgp Description: PGP signature
