[clamav-users] VirusDB Updates Broken?

[Paul Kosinski]

Joel,

Sorry to have been somewhat cryptic: I assumed the context of the
posting I was nominally replying to.

By "broken", I meant that freshclam cannot retrieve daily.cvd files
from the new CloudFlare IPs. In fact, I just now removed mirrors.dat,
and all(?) the new CloudFlare IPs report "not synchronized", probably
due to the ping.clamav.net failures (see below):

  WARNING: Mirror 104.16.185.138 is not synchronized.
  WARNING: Mirror 104.16.186.138 is not synchronized.
  WARNING: Mirror 104.16.187.138 is not synchronized.
  WARNING: Mirror 104.16.188.138 is not synchronized.
  WARNING: Mirror 104.16.189.138 is not synchronized.

The command "host -t txt current.cvd.clamav.net" reports as follows:

  current.cvd.clamav.net descriptive text "0.100.0:58:24699:1530048540:1:63:47550:322"

But the freshclam log reports some variant of:

  Querying daily.0.85.0.0.6810BD8A.ping.clamav.net
  Can't query daily.0.85.0.0.6810BD8A.ping.clamav.net
  Giving up on db.us.clamav.net...

None of my local recursive DNS, my off-site Web server (in another
state), or (apparently) 8.8.8.8 or 8.8.4.4 can resolve
daily.0.85.0.0.6810BD8A.ping.clamav.net, but mxtoolbox.com resolves it,
(via ns4.clamav.net) to:

  5.9.14.57 at Hetzner Online AG (AS24940)

Weird.

However, it seems I *can* get at the daily.cvd file by means of direct HTTP
access to "http://db.us.clamav.net/daily.cvd", which accesses the same
CloudFlare IPs that are allegedly "not synchronized".

The result of all this confusion is that the last time I got a
daily.cvd via freshclam was before CloudFlare:

  Monday 25 June 2018 at 09:06:26
  Database updated (6556585 signatures) from db.us.clamav.net (IP: 200.236.31.1)

I am going to have to use the direct HTTP until [whenever]?
