I'm running 0.103.3 on all 3 of my ClamAV installations. On one of the systems (where I have very detailed logging of freshclam), main was still at 59 (today at 7:43 AM EDT), and freshclam correctly downloaded daily 26231 over 26230. Later on, from the same system, main was allegedly (DNS TXT) supposed to be at 60, and daily was supposed to be at 26232, but *both* failed to download at least 7 times (15:43 EDT through 21:43). This may, of course, be essentially the same problem I had with Cloudflare's BOS (Anycast) POP a couple of years ago, which made me give up putting any more work into setting up my own mirror. _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
