I create a tunnel to my server that is running squid using ssh and
running with a default (debian) configuration. My server is
dual-stacked (public IPv4 and IPv6 addresses) while the client is a
IPv4 only.
Over the past few days I have been developing a website and found an
oddity on what address is reported specifically from my laptop while
using this tunnel. It appears that Squid is alternating between
using
the IPv4 and IPv6 address (the destination website is also dual
stack)
and as such was making it difficult for myself to deal with these
sessions.
So this appears to be happening because:
* Squid is choosing to use IPv6 and IPv4 randomly /
interchangeably causing server side session checking to fail (phpBB
has an IP Address check for example)
So my question are:
* Did I miss something in the configuration file?
hmm my squid boxes are also dual stacked and I was not able to force ipv4 precedence over ipv6 (see : /etc/gai.conf - http://tools.ietf.org/html/rfc3484)
Squid does not use the kernel resolver. And also does not (yet) read the
gai.conf file for its own use.
These settings can be achieved by setting the DNS resolver Squid uses as
its source to send IPs in the rfc3484 ordering you want. Squid will
still fetch AAAA before A though so rfc3484 only affects within a set of
same protocol IPs.
