This issue seems to be related with ipv6: $ grep ipv6 /etc/modprobe.d/blacklist blacklist ipv6
But alias net-pf-10 ipv6 was just commented out in /etc/modprobe.d/aliases alias net-pf-10 off - solve the problem for me. -- To UNSUBSCRIBE, email to debian-apache-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
