    search for a binary named crond, get the 2nd column of the output(the binary), then pass to rpm to look for it's belonging package. Note that in RHEL/CentOS cron daemon is named crond but not in some other OS. So I edited and use "crontab" instead which is more general. You can even filter from ps to figure out what binary is running

On your centos system: rpm -q vixie-cron

Should be something like vixie-cron-4.1-77.el5_4.1

In EL6, you can check the version of cronie (contains crond) with yum:

sudo yum list installed cronie

fyi, cronie replaced vixie-cron in EL6.
