Preventing overloads at the database.clamav.net servers

Two cents (and not even my own):

I would like to draw your attention to the thread "proposal: best
practices for cron jobs in RPM packages" at the freshrpms list:

http://lists.freshrpms.net/pipermail/freshrpms-list/2004-June/009875.html

In short, the conclusion of the thread is that packages (such as
freshclam) should randomly select and establish the time at which their
cron jobs run, in order to prevent overloading download servers.

Thanks for a great package!

There should be a built in random delay into freshclam, and probably also some
means to determine the closest mirror despite what the rr ns rr says.

I disagree. freshclam is a command line utility and it must work
immediately on demand.

Already implemented. See http://www.clamav.net/doc/mirrors/

I meant that it should be a optional switch, like "--random", "-r".

Cool!, I didn't know that.

Thanks.

I see no need for that. You can easily randomize freshclam starting time
with help of package installation scripts. Example from my package for
upcoming ALT Linux distro:

# randomize time of database updating (in order to distribute load on servers evenly)
RNDM=$[$RANDOM/546]
/usr/bin/subst s/^[0-9]*/$RNDM/ %_sysconfdir/cron.d/freshclam
