Update failed. Your network may be down or none of the mirrors listed in
/etc/freshclam.conf is working. Check
http://www.clamav.net/doc/mirrors-faq.html for possible reasons.



I'm able to telnet to port 80 at db.local.clamav.net without issue. but I
get a 403 forbidden when i try to download main.clv directly with wget (wget
http://db.local.clamav.net/main.cvd)

I'm not convinced that it's a network issue. Can anyone explain why
freshclam appears to be trying IPv6 even though the host only has an IPv4
address on eth1?

Re: [clamav-users] Freshclam network unreachable [ In reply to ]
Hello Adam,

Thank you for your email. As a result of events documented in places here:
https://lists.clamav.net/pipermail/clamav-users/2021-March/010577.html
and
https://lists.clamav.net/pipermail/clamav-users/2021-March/010543.html

We’ve been forced to take emergency measures to protect the ClamAV environment.

Please Immediately switch to using Freshclam or https://github.com/micahsnyder/cvdupdate to update your AV definitions.

Sorry for the inconvenience, but we are currently in emergency mode and have to make several drastic changes over the several days.

I'm able to telnet to port 80 at db.local.clamav.net<http://db.local.clamav.net/> without issue. but I get a 403 forbidden when i try to download main.clv directly with wget (wget http://db.local.clamav.net/main.cvd)

I'm not convinced that it's a network issue. Can anyone explain why freshclam appears to be trying IPv6 even though the host only has an IPv4 address on eth1?

There's been a flurry of recent activity on the mailing list about the
abuse of ClamAV DB service, see the archives for more detail but I
think Joel's reply has answered this part.

I think it is a network issue. Most network software doesn't know
what interface it's going to use, it just asks the resolver for an
address. Your resolver provides an IPv6 address and freshclam tries
to use it.

To build freshclam (and everything else) from source without IPv6
support you could (at least theoretically, I've never tried it myself)
use the 'configure' option '--disable-ipv6'. Alternatively, which I'd
suggest is preferable, you can fix the network's IPv6 connectivity.

Re: [clamav-users] Freshclam network unreachable [ In reply to ]
Adam,

Some of your log lines like “Ignoring mirror" indicate a version older than 0.102. 0.102 had a major freshclam update to the network code. It uses libcurl now. Please try to install 0.102.4 or 0.103.1 if you can. I think a newer version of freshclam may work for you.

Regards,
Micah

Well, I think they don't want to, but they might think they do. The
firewalling for example can be a whole can of worms, and there might
not even be an IPv6 route to the outside world. I don't know how many
providers still don't offer native IPv6 on their broadband packages,
but I'm fairly sure many (including ours) don't. We use he.net for
our IPv6 presence - it just needed some address/protocol juggling in
one of the firewalls.

zero support for it within 130 miles of me, Well, maybe in Charleston
WV, but that is still 100 miles. ipv6 traffic is blocked at my cable
supplied modem sitting on a shelf at the other end of this smallish
room. So I obviously disable it to make ipv4 the default hookups here.

Re: [clamav-users] Freshclam network unreachable [ In reply to ]
Thanks team, was just wondering.

zero support for it within 130 miles of me, Well, maybe in Charleston
WV, but that is still 100 miles. ipv6 traffic is blocked at my cable
supplied modem sitting on a shelf at the other end of this smallish
room. So I obviously disable it to make ipv4 the default hookups here.

There's been a flurry of recent activity on the mailing list about
the abuse of ClamAV DB service, see the archives for more detail but
I think Joel's reply has answered this part.

I'm not convinced that it's a network issue. Can anyone explain why
freshclam appears to be trying IPv6 even though the host only has
an IPv4 address on eth1?

I think it is a network issue. Most network software doesn't know
what interface it's going to use, it just asks the resolver for an
address. Your resolver provides an IPv6 address and freshclam tries
to use it.

To build freshclam (and everything else) from source without IPv6
support you could (at least theoretically, I've never tried it
myself) use the 'configure' option '--disable-ipv6'. Alternatively,
which I'd suggest is preferable, you can fix the network's IPv6
connectivity.

Re: [clamav-users] Freshclam network unreachable [ In reply to ]
"Out of procedural curiosity, why would someone want to disable ipv6?"

Although our FIOS connection supports IPv6, our firewall/gateway complex, which I custom built from scratch 16+ years ago using iptables etc., doesn't. Since this firewall/gateway also does lots of inter-LAN routing and blocking (not to mention some source-based iproute2 stuff), it would have to be rewritten extensively. I don't have time to do this, especially given that there is still (after all these years) nothing critical that is IPv6 only.

P.S. It would have been nice if the designers of IPv6 hadn't made it almost totally incompatible with IPv4 (unlike x64 vs x86). What if, when Ma Bell introduced direct distance dialing in the 1960s, they had made the new area-code scheme require that every customer who wanted to use area-codes get a new phone number with a totally different format, and replace their telephone handset?
