I use vixie-cron too. No idea what the differences between them all are tho.

I don't have any ideia of the differences too, but vixie-cron didn't let me.

I use vixie-cron too - emerge sync at mid-day, emerge -uDpv world at 12.30 and emerge -uDpv system at 12.35; very useful for keeping an eye on what needs updating without actually doing anything.

I use it to Check for email; Backup; emerge sync every 4 hours.

i don't use it...

Emerge sync every 4 hours! The recommended is once a day max - is there any need to put the servers under that pressure?

Just my thoughts but I think that's a hell of a lot of syncing

I agree, six times a day is way more than you need. The only reasons I can think of for syncing more than once a day are urgent security fixes, and if you absolutely can't wait to get a new version of something (i.e. there's a new feature you urgently need). Every four hours is excessive.

dcron

hourly: ntp sync against ntp1.ptb.de
daily: updatedb (annoying but useful), makewhatis, logrotate
monthly: fetch new pciids

dcron ...
4 times an hour I sync my IP to my DNS service. Evil ISP, making me need those 4 syncs an hour.

I use fcron, as it deals very nicely with events that would have happened while the computer was switched off. My only item is:

Code: Select all

%weekly,runas(ian) * * /usr/sbin/gentoo-stats --update && date >> /home/ian/last-gentoo-stats

to send my Gentoo stats. Not very essential really.

vixie-cron, cuz the install guide seemed to point me that way.

Once a day for both

emerge sync (which my other 3 boxes sync off of when needed)
mythfilldatabase

how does it handle it exactly?

Ian Goldby · Post by **Ian Goldby** » Sat Apr 10, 2004 10:06 pm

I don't exactly remember. I did spend a while comparing the various crons, and fcron seemed to just do the Right Thing. In the example I gave, it just runs the command next time the computer is on, with a sensible delay to allow the boot to finish first. But I suspect there are other options too.

Blue Fox · Post by **Blue Fox** » Sat Apr 10, 2004 10:16 pm

Uhm... I think that vixie-cron doesn't do that... so my next cron will be fcron =)

I use vixie-cron, just caus that's what teh install guid recomended.

Is this necessary?

PowerFactor · Post by **PowerFactor** » Sat Apr 10, 2004 10:28 pm

eventualy

Gentoo's default /tmp cleaning boot script(it's in bootmisc) doesn't clean /tmp very agressively. And sometimes I don't reboot for a long time anyway. Especialy my server.
