Description
Nginx 1.4.0 is not binding to IPv4 with [::]:80 on Ubuntu 13.04 when net.ipv6.bindv6only is set to false.
server {
listen [::]:80;
...
}
$ sysctl net.ipv6.bindv6only net.ipv6.bindv6only = 0
$ sudo netstat -npl | grep nginx tcp6 0 0 :::80 :::* LISTEN 4265/nginx.conf
I can fix this by explicitly specifying Nginx to bind also to IPv4.
server {
listen 80;
listen [::]:80;
...
}

Ah, I see. Thank you Maxim! Maybe the wiki page should be updated to reflect this information: http://wiki.nginx.org/HttpCoreModule#listen

We do not maintain wiki, please refer to official docs in the future.
Note:
See TracTickets
for help on using tickets.

This is expected behaviour, the ip6only is now consistently set to on, see http://nginx.org/en/CHANGES:
Changes with nginx 1.3.4 31 Jul 2012 *) Change: the "ipv6only" parameter is now turned on by default for listening IPv6 sockets. ...You should either list both IPv6 and IPv4 listen sockets, or explicitly switch off ipv6only for IPv6 sockets.
