[gentoo-user] ntp problems

[David Corbin]

ntp-client is in my "default" run level.  However, when I it runs at boot 
time, I get this error message:

12 Mar 09:06:24 ntpd[9516]: cap_set_proc() failed to drop root privileges: 
Operation not permitted
12 Mar 09:06:26 ntpd[9561]: parent died before we finished, exiting


If I run it as root manually, it runs fine.  

Any ideas as to what the problem is?

Add nodroproot to your USE flags and remerge ntp

I will, but why does it work fine "from the command line"?

Hi,
Because when it wants to drop it's privileges from root to e.g. ntpd (user or 
group) it can't - get's killed.
Usually permission problems or in this case it/ntpd can't access /proc to set 
time (cap_set_proc()).
Just a sidenote, recently (a day ago) exchanged "ntp" for "openntpd" (from 
OpenBSD) on a hardened router, because ntp wanted to lock too much memory 
(RLIMIT_MEMLOCK - from 32K (default) -> ~8 MB) and other minor issues.

I don't mean to sound like child who continues to go "but why?".  Still, it 
doesn't make sense to me.

First, I don't understand how root could ever have a permission problem try to 
"downgrade its privleges".

Second, I don't understand how it could not have the require privileges during 
the boot process (presumably running starting as root), and yet it works when 
I run it by hand as root.
