[Pdns-users] IPv4 and IPv6 sockets at the same time

[Marten Lehmann]

Hello,

there is no option "local-ipv6" in pdns recursor: 
http://doc.powerdns.com/built-in-recursor.html

local-address=::1,127.0.0.1 is partially working: pdns listens on ::1 
and 127.0.0.1. But it only answers on 127.0.0.1, not ::1 when both ip 
addresses are specified.

Could someone please try running pdns recursor with this config file:

setuid=pdns
setgid=pdns
local-address=::1,127.0.0.1
max-negative-ttl=5
allow-from=0.0.0.0/0

You can also use

local-address=127.0.0.1,::1

order doesn't seem to change the symptom.

# netstat -plntu | grep 53
tcp        0      0 127.0.0.1:53                0.0.0.0:* 
     LISTEN      673/pdns_recursor
tcp        0      0 ::1:53                      :::* 
     LISTEN      673/pdns_recursor
udp        0      0 127.0.0.1:53                0.0.0.0:* 
                 673/pdns_recursor
udp        0      0 ::1:53                      :::* 
                 673/pdns_recursor

So pdns recursor is definetely binding to the sockets as specified.

But if you do a

dig google.com @::1

you won't get any answer (at least I don't on a CentOS 5 system with 
firewalls disabled for testing).

dig google.com @127.0.0.1

does work however.

Should I file a bug report?

Kind regards
