Package: tomcat6
Version: 6.0.20-9
Severity: important

In current versions of squeeze, the default value of IPV6_V6ONLY is
true:

ganymede:~# cat /etc/sysctl.d/bindv6only.conf | egrep -e '^([^#])'              
                          
net.ipv6.bindv6only = 1

This causes tomcat6 to not accept IPv4 connections by default, as it
only binds to an IPv6 socket and apparently doesn't change the
IPV6_V6ONLY socket option from its new default value.
