RE: [squid-users] IPv6 error prevents Squid start

Also disabled IPv6 for eth0:
/etc/sysconfig/network

/etc/sysconfig/networking-scripts/ifcfg-eth0
        IPV6INIT=no
        IPV6_AUTOCONF=no

/etc/modprobe.d/ipv6.conf containing
        alias net-pf-10 off
        alias ipv6 off

/etc/modprobe.d/blacklist.conf
        blacklist net-pf-10 < add to bottom of file

I know have another site that is throwing the Ip::Address::GetSockAddr error and squid will not start at all. Is it possible some library or squid dependency may have got updated with "yum update" and upset the apple cart? I appreciate your time. Please advise.

Squid is written to operate on hybrid dual-stack systems (dual stack with v4-mapping abilities). Split-stack and non-mapping dual-stack system support is still incomplete, but should be working in 3.2.0.17.

I will need the backtrace to know where the trouble component is and what it is trying to do with an IPv6 [::] / "*" address.

For now pause the updates cycle and possbly check the system IPv6 settings on the barfing machines are either enabled, or disabled in a way Squid can detect (IPv6 socket() creation disabled).
