[pkg-lighttpd] Bug#864475: lighttpd: Does not bind to some ipv6 port

[Johannes Schlumberger]

Package: lighttpd
Version: 1.4.45-1
Severity: normal
Tags: ipv6

Dear Maintainer,
I am trying to have my lighttpd listen on port 80 and 443 for both ipv6 and
ipv4. Please see attached config for how I am trying to achieve this.
It ends up listening on 80 and 443 for ipv4, but only on port 80 for ipv6. I
would expect it to listen to port 443 for ipv6 as well. There is nothing
else listening on this port.

$ sudo netstat -tulpn | grep lighttpd
tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      10525/lighttpd
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      10525/lighttpd
tcp6       0      0 :::80                   :::*                    LISTEN      10525/lighttpd
$ sudo netstat -tulpn | grep 443
tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      10525/lighttpd
$ for prot in 4 6; do for port in 80 443; do echo -n -e "Testing with port $port \
and ipv${prot}:\t"; echo exit | nc -q 1 -v -$prot localhost $port;done ;done
Testing with port 80 and ipv4:  Connection to localhost 80 port [tcp/http] succeeded!
Testing with port 443 and ipv4: Connection to localhost 443 port [tcp/https] succeeded!
Testing with port 80 and ipv6:  Connection to localhost 80 port [tcp/http] succeeded!
Testing with port 443 and ipv6: nc: connect to localhost port 443 (tcp) failed: Connection refused


Please let me know if I can help with any other information.
thank you for your work,
	Johannes
