Hmm, right (r2758: bind to IPV6-only if ipv6 address was specified).
Could you try with a clean conf and post a strace of the error?
$ ltrace lighttpd -f /etc/lighttpd/lighttpd.conf
...
memcpy(0x081319b0, :80, 3) = 0x081319b0
strrchr(:80, ':') = :80

fcntl(4, 2, 1, 0xb7584ff4, 0xb75863a0) = 0

So: use_ipv6 is not 1 because host_token has no [::] for some reason.
Extract from strace follows.
# dpkg --purge lighttpd
# dpkg --install /var/cache/apt/archives/lighttpd_1.4.28-1_i386.deb

Well, yes, for _new_ installs, but this is a conffile so it keeps the existing value for existing installations. That sucks, IMO it should've been set to 0 before the file being removed. My own analysis is the same as before: relying on anything about the bindv6only setting is just asking for trouble. lighttpd needs to set or clear the IPV6_V6ONLY option itself for ipv6 sockets, or autoconfigure correctly at runtime. This bug was about Lighttpd relying on v6only = 1. So in your case it should've worked. Lighttpd actually sets v6only = 1 itself (AFAIK) now.

Hi, not sure if it is relevant at all anymore but I hit this too in the following environment: * debian stable * custom kernel with CONFIG_IPV6=y * debian unstable chroot for testing unstable packages Obviously /proc/sys/net/ipv6/bindv6only is false since it is not set by the debian stable system. (And as noted earlier setting it to true would destroy java networking from all other users of the system.) I can confirm that changing #include_shell /usr/share/lighttpd/use-ipv6.pl to server.socket = [::]:80 indeed makes it possible to start lighttpd. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

I’m using a Debian kernel now; I’ll try rebuilding a kernel with ipv6 disabled and get back to you in the next few days. Was this fixed upstream or something? I thought the problem was caused by your kernel option. bindv6only is now enabled by default in netbase AFAIK.

Maybe it could be considered a kernel bug: if ipv6 support is disabled (because built as a module) at the time the netbase init script runs, then it cannot enable bindv6only. The sysctl errors out. But surely programs should not be relying on bindv6only to be set! That is just asking for trouble. There _are_ going to be administrators who disable it, and we should accomodate them. In other words, lighttpd needs to set or clear the IPV6_V6ONLY option itself for ipv6 sockets.
