Hello
Running clamav 0.97.6 and then 0.97.8 on a Debian squeeze server, since
14 Feb this year freshclam has been consistently failing with
ERROR: getpatch: Can't download daily-16682.cdiff from database.clamav.net
WARNING: Incremental update failed, trying to download daily.cvd
...
Ignoring mirror 217.135.32.99 (has connected too many times with an
outdated version)
ERROR: Can't download daily.cvd from database.clamav.net
Giving up on database.clamav.net...
Update failed. Your network may be down or none of the mirrors listed
in /etc/clamav/freshclam.conf is working. Check
http://www.clamav.net/support/mirror-problem for possible reasons.
One solution (delete daily.cvd and run freshclam again) has been covered
here on 15 Feb
<http://www.gossamer-threads.com/lists/clamav/users/57663#57663>.
However, that solution is not necessarily obvious, and there is other
advice out there such as reducing number of Checks per day to less than
6 and waiting at least 24 hours
<http://forums.debian.net/viewtopic.php?f=5&t=97058>, which didn't work
for me. (The upgrade to 0.97.8 also reduced Checks to 3.)
Another solution that I found was setting a HTTPProxyServer and
HTTPProxyPort in freshclam.conf. So are the mirrors blocking the IPv4
address used by my freshclam? And if so, why, is there any way to
remove the block, and why is the restriction only enforced when the old
daily.cvd is present?
I'm wondering how many ClamAV installations there might be out there
which are "stuck on updates prior to daily.cvd version
16685" months later, without the owners even knowing. The updates
usually work very nicely thank you, and the errors may not get noticed.
Could this be fixed by an update to the freshclam client, or perhaps to
the mirrors? At least could
http://www.clamav.net/support/mirror-problem be updated to reflect this?
Thanks
CK
