Crond messages on /var/log/messages

Hi Guys,

I just noticed that, on my server at home, I have a bunch of these messages:

May 31 08:50:01 yoruba crond(pam_unix)[5829]: session opened for user root by (uid=0)
May 31 08:50:03 yoruba crond(pam_unix)[5829]: session closed for user root

May 31 09:05:03 yoruba crond(pam_unix)[5837]: session closed for user root

I don't remember scheduling anything, and if I do

crontab -l

I get

no crontab for root

.

Does anyone knows what can it be or how can I find what it is?

[pbharris]

are you running a localization for yoruba? I also see cron job enteries for root but know they are okay (can't remember them now, at work).

[trickster]

Nope, no localization. I dimly remember trying to make yum run automagically, but don't think I got it to work. However, it stil does not show on crontab. ???

[Outlaw]

Look in /var/log/cron*, maybe run-parts /etc/cron.hourly etc? That kind of activity won't be in root's crontab.

Radar is the man!!
