A few days ago, I programmed some pre-tests so as to avoid running freshclam until *both* the DNS TXT record and the first few bytes of daily.cvd (obtained via curl) agree that there is a new version which *actually* is available for download via freshclam.
It turns out that doesn't cover all the possible mis-synchronizations. Today, my tests showed the new daily.cvd was indeed available (and freshclam downloaded it), but the new bytecode.cvd wasn't *really* available, so freshclam reported overall failure. Worse yet, the curl test on bytecode.cvd says that the new one still isn't available one hour later. Our enhanced log follows. It shows that daily.cvd #24761 became available by 14:18 (EDT), but bytecode.cvd #325 was *not* really available even though the DNS TXT records said it was, and it still wasn't really available at 15:18 (or even now, at 15:30). I guess I'll have to enhance my pre-test to demand that *all* of daily.cvd, bytecode.cvd and main.cvd pass the curl tests before invoking freshclam. (Today, this would *any* updating even more.) ------------------------------ Wednesday 18 July 2018 at 14:03:01 ------------------------------ /opt/clamav/bin/testclam-external --> DNS D 24760/24760 B 324/324 M 58/58 ------------------------------ Wednesday 18 July 2018 at 14:18:01 ------------------------------ /opt/clamav/bin/testclam-external --> UPD D 24761/24761/24760 B 324/325/324 M 58/58/58 /opt/clamav/bin/freshclam -v --stdout --on-update-execute=EXIT_1 Current working dir is /opt/clamav.d/clamav.0.100.1/share/clamav Max retries == 1 ClamAV update process started at Wed Jul 18 14:18:04 2018 Using IPv6 aware code Querying current.cvd.clamav.net TTL: 1798 Software version from DNS: 0.100.1 main.cvd version from DNS: 58 main.cvd is up to date (version: 58, sigs: 4566249, f-level: 60, builder: sigmgr) daily.cvd version from DNS: 24761 Retrieving http://database.clamav.net/daily.cvd Using ip '10.11.14.160' for fetching.
