[squid-users] Squid3: icmp_sock: (97) Address family not supported by protocol / pinger: Unable to start ICMPv6 pinger

Thu Jun 23 07:54:41 UTC 2016

Hey,

Pinger is not a must but a luxury piece of software.

It will make your and others life easier but you can avoid it playing with the configuration option:

http://www.squid-cache.org/Doc/config/pinger_enable/

And if you have disabled ipv6 in some way it would be probably wise to start thinking about just enabling it if not using it.

Since you have compiled squid by yourself(right?) then you need to disable ipv6 in the squid flags.

I do not think it's a very good idea these days but you are the user\admin\client.

All The Bests,

Eliezer

I notice that I've comnpiled squid3 with --enable-icmp but I don't need thsi option because I don't work eith parent caches.

So I will try to reconfigure squid3 withouth the ICMP option (no pinger at all), and I expect not to see any IPv6 warning.

I can't see anything about IPv6:

cat /etc/default/networking:

# Configuration for networking init script being run during

# the boot sequence

# Set to 'no' to skip interfaces configuration on boot

#CONFIGURE_INTERFACES=yes

# Don't configure these interfaces. Shell wildcards supported/

#EXCLUDE_INTERFACES=

# Set to 'yes' to enable additional verbosity

#VERBOSE=no

cat /etc/network/interfaces:

# This file describes the network interfaces available on your system

# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*    (this path is empty)

# The loopback network interface

auto lo

iface lo inet loopback

# The primary network interface

allow-hotplug eth0

iface eth0 inet static

        address x.x.x.x

        netmask 255.255.252.0

        network x.x.x.x

        broadcast x.x.x.x

        gateway x.x.x.x

        # dns-* options are implemented by the resolvconf package, if installed

        dns-nameservers x.x.x.x

Well, that certainly confirms that IPv6 is disabled on your machine (from the
lack of lines such as "inet6 addr:").

You say "I haven't disabled the IPv6 protocol, no references in
/etc/default/grub neither in systcl asociated file."

Something (or someone) has certainly disabled IPv6 on this machine, though.

What are the outputs from:

        grep -v ^# /etc/default/networking

        cat /etc/network/interfaces

?
