Package: apache2.2-common Version: 2.2.22-13 Severity: normal Tags: ipv6 Reported to upstream as requested in Ubuntu bug 1207384: https://bugs.launchpad.net/bugs/1207384
Apache fails to start on boot when attempting to bind to an IPv6 address. boot.log shows the following (IP changed for privacy purposes): (99)Cannot assign requested address: make_sock: could not bind to address [2001:db8::1]:80 no listening sockets available, shutting down Unable to open logs Action 'start' failed. The Apache error log may have more information. * Starting web server apache2 [fail] Starting manually (apachectl start) after boot starts the daemon as expected. Here is the inet6 section of my /etc/network/interfaces. Again, IPs removed for privacy. The post-up/pre-down route directives are required to access my provider's network: iface eth0 inet6 static address 2001:db8::1 netmask 64 up /sbin/ifconfig eth0 inet6 add 2001:db8::2/64 down /sbin/ifconfig eth0 inet6 del 2001:db8::2/64 post-up /sbin/ip -f inet6 route add 2001:db8::ff:ff:ff:ff dev eth0 post-up /sbin/ip -f inet6 route add default via 2001:db8::ff:ff:ff:ff pre-down /sbin/ip -f inet6 route del default via 2001:db8::ff:ff:ff:ff pre-down /sbin/ip -f inet6 route del 2001:db8::ff:ff:ff:ff dev eth0 Doing a little bit of research, it appears apache is trying to bind to an IP in the tentative state. (source: http://pyro.eu.org/how-to/micro/nginx-cannot-assign-requested-address-ipv6.txt). Adding the while loop shown on at that URL to /etc/network/interfaces did not help; however, adding it to the beginning of /etc/init.d/apache2 resolved the issue. Suggest implementing something similar as a fix; have /etc/init.d/apache2 check for IPs in the tentative state and sleep until resolved. -- Package-specific info: List of enabled modules from 'apache2 -M': alias auth_basic authn_file authz_default authz_groupfile authz_host authz_user autoindex cgid deflate dir env mime negotiation reqtimeout setenvif status -- System Information: Debian Release: 7.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages apache2.2-common depends on: ii apache2-utils 2.2.22-13 ii apache2.2-bin 2.2.22-13 ii lsb-base 4.1+Debian8+deb7u1 ii mime-support 3.52-1 ii perl 5.14.2-21 ii procps 1:3.3.3-3 Versions of packages apache2.2-common recommends: ii ssl-cert 1.0.32 Versions of packages apache2.2-common suggests: ii apache2-doc 2.2.22-13 pn apache2-suexec | apache2-suexec-custom <none> ii w3m [www-browser] 0.5.3-8 Versions of packages apache2.2-common is related to: pn apache2-mpm-event <none> pn apache2-mpm-itk <none> pn apache2-mpm-prefork <none> ii apache2-mpm-worker 2.2.22-13 -- Configuration Files: /etc/apache2/ports.conf changed: NameVirtualHost 198.100.152.164:80 Listen 198.100.152.164:80 NameVirtualHost [2607:5300:60:bae:2::1]:80 Listen [2607:5300:60:bae:2::1]:80 <IfModule mod_ssl.c> # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl # to <VirtualHost *:443> # Server Name Indication for SSL named virtual hosts is currently not # supported by MSIE on Windows XP.
