Fix your freshclam setup or get blacklisted

We are seeing a lot of useless traffic on our mirror servers.
It looks like there are many broken freshclam clients still running.

Once again, we urge you to upgrade to ClamAV 0.80 and take advantage of the new DNSDatabaseInfo option, which allows to check for a new version of the database with a single DNS query. Verify that your freshclam.conf contains:


Check out the doc for more info.

Unless you are using DNSDatabaseInfo, please keep the check frequency below once per hour.

1) if you run freshclam from crontab, check that you have an entry like the following:

N * * * * /usr/local/bin/freshclam --quiet

where N is a random integer between 3 and 57 and is not a multiple of 10.

Do NOT use anything like this:

* * * * * /usr/local/bin/freshclam --quiet
*/N * * * * /usr/local/bin/freshclam --quiet

2) if you run freshclam from crontab, make sure that you are
_not_ using the -d flag (see the manpage for more info).

Abusing clients will be added to a black list and won't be able to
download our database anymore.
