Severity: important

Coin,

Netbase has recently introduced the sysctl-setting
net.ipv6.bindv6only=1 in /etc/sysctl.d/bindv6only.conf and this setting
will probably be the default in squeeze.

This setting disable the automatic bind-mapping from ipv6 to ipv4, then if you want to listen on both protocol, you've got to bind on both. The former behavior is broken as it does not allow useful combinations and does not respect standards established on all other OSes. With the 'inet6' ejabberd setting then it listen on ipv6 only, which is not what is expected.

More info on the problem here :

Regards.
