ntpd issues

I did an update today as part of my daily grind.. and after an update I regenworld, --depclean, and revdep-rebuild...

Today in my depclean it wanted to remove swig & libcap. So I tested this on my systems box then did a revdep-rebuild and it wanted to build ntp again. This went through fine. Now however ntpd wont run..

So I tried to re-emerge libcap and swig then ntp and it still wont start.

Not sure why this is. I have the same exact setup on 5 other boxes. All want to remove swig & libcap (ya i know depclean is not stable, but I never ran into a problem with it until now)

equery depends libcap displays ntp & pax-utils need it.

I am not sure what I could have messed up that the steps I have already taken do not fix. Any ideas?

my log when i try to start..

I'm having pretty much the same problem, which seemed to occur after I recently updated to GCC 4.1.1 and recompiled my whole system.

I never removed libcap and swig (even though emerge --depclean wants to remove them), but nonetheless, ntpd won't start. I've tried recompiling all of these packages, but ntpd always fails to start.

This definitely started happening after I did an "emerge -e world", so somethings going on.

By the way, I can't figure out any way to get ntpd to spit out verbose logging. If you try to run it with the -d or -D options, it will tell you that ntp is not compiled with debug support. There's also no option you can put into /etc/ntp.conf that will increase the amount of logging written to the log file (by default, all logging is enabled).

hmmm this is the only machine I run gcc 3.4.6 on. I wonder if this could have happened when I did my emerge -e and I just failed to notice the issue until now. The rest of my servers are still running gcc 3.3.6.

I also fail to get any decent logging.

It seems that others have had this problem when linuxcaps wasn't correctly configured.

Even though I've always run on a kernel with CONFIG_SECURITY=y and CONFIG_SECURITY_CAPABILITIES=y, I'm wondering if it has something to do with this.

I can't test anything until I have access to my machine later in the day. If you want to try something, see if you can run ntpd as root (you may need to remerge it with the "nodroproot" USE flag). You could also try unsetting CONFIG_SECURITY and CONFIG_SECURITY_CAPABILITIES, since leaving them unset is supposed to enable linuxcaps anyway.

Yes I am able to run it as root as I said in my first post.

I just tried to set linuxcaps as a module and ntpd still failed.
I also tried to compile it into the kernel and it still fails.

Even tried to re-merge libcap and ntp each time..

I have no idea what is going on :p

**edit I also tried both unset..

An update:

I recompiled pax-utils and ntp with the USE flag "caps" enabled, and now ntpd starts successfully.

I never had to use this USE flag before, so I don't know what changed. Also, I still don't understand why swig and libcap don't register as dependencies of anything, even with the caps USE flag turned on, since:

Same here, never use 'caps' flag

This fixed up my deps also.

I guess I should start reading the changelogs more

Thanks working well now.

I was having the same problem with ntpd after emerge -e wolrd. Using the "caps" use flag does fix the problem, however when i rebuilt my new kernel i, i built CONFIG_SECURITY_CAPABILITIES as a module and forgot i had to
