Freshclam needs a "connection failed" counter. Reset the "connection failed" counter to zero after a successful transfer. To select a mirror, add "connection failed" + "success" in the mirror selection scheme. This will help push persistent dead sites down in preference, but still keep them available for when the network starts working. This recent episode has exposed an opportunity to improve freshclam's handling of persistently dead mirrors. In this case, a mirror was unreachable from a fairly large section of the internet, but worked fine for others. While this event is notable for its scale, it is probably not terribly uncommon on a smaller scale. Currently, a persistently dead mirror will have an artificially low (possibly zero) failure count, and a low (possibly zero) success count. Since freshclam prefers mirrors with low failures and low successes, this makes persistently dead mirror a "connection attractor" where it will be tried even more frequently. We've seen this in action with this recent episode where the dead mirror was frequently tried first for many people. Freshclam needs some way to identify persistently dead mirrors. While it would be a mistake to ignore a host after a low number of transient connection errors, we're shooting ourselves in the foot to never consider connection errors. -- Noel Jones -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOdL5aAAoJEJGRUHb5Oh6gpGcIAKVStnNiE49b1DRVVPphcHU0 98aJr5yp9rDwIoWFOumxFxQTN2D6YREz/FD3g/gQmdIc6DE9yzItqBSMQURfH5/u Qnw4FZjxmkkUrKm/UV3+2isbDQn//s9xYQYL1nj/kz+fq480mLK/1d90L/dHAJfj /RaNwaRgpmwpZ5dDxWuiVfCI3EuPZIh5gTs9NvIQs3rVUsXexC6y/GPszv2nqmVA yfqtbY0YfCx2Z6GUzBa1C2ZgHDOMRuK0ys2bkh8P5AOM9eGFVD9EFxMJ1LNtW5L4 7HwKY9VPKNGokKIge01P7G/DwLgEbyTW76PfA6cHgoNNC88UiBlxjNnAwtQZ8VM= =eQvA -----END PGP SIGNATURE----- _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://www.clamav.net/support/ml
