<body><div style="text-align: left;">Thanks, makes sense.<br><br>However, on my home computer, it is more vital that jobs are run when I say they should be run, and not according to a random formula. If the football game starts at 1630, I don't care to be reminded up to 68 minutes afterward :-)<br><br>I guess there's no harm in removing that 000-delay.cron job, eh?<br></div><br>kwhiskerz{<br><br><blockquote style="border-left: #008080 2px solid; padding-left: 5px; margin-left: 5px; margin-right: 0px;"><hr id="EC_stopSpelling">Date: Tue, 30 Jan 2007 15:14:26 -0500<br>From: pepebuho@gmail.com<br>To: fedora-list@redhat.com<br>Subject: Re: cron problem<br><br><div>Oftentimes, Cron is used to setup communication with other servers to update Clamav or Spamassassin, maybe to run Yum check-update.</div>
<div>The issue is that if everybody is hitting the servers on the hour, we have instataneous hourly DOS attacks on those servers.</div>
<div>The random delay prevents this by randomizing the access time while guaranteeing that within the next XX minutes you will run the update</div>

<div>On the weekend an update to cron came out with this new script: /etc/cron.daily/000-delay.cron<br><br>What it appears to do is to introduce a random length of delay before cron/anacron run.<br><br>What is the point of introducing randomness into a finely tuned system?
<br><br>When one sets up crontab/anacrontab to go off at precisely a certain time, one expects it to run at the time specified, and not at some random time in the next 68 minutes!<br><br>What purpose does this serve?</div>
