Hi,
I am having difficulties running knot on an dualstack host. I want Knot
to listen on all IPv4 and all IPv6 interfaces. I am using this
interfaces section in config file:
interfaces {
allv4 { address 0.0.0.0; }
allv6 { address [::]; }
}
Using this config, Knot listens only on v4 address and gives an error
binding the v6 address:
2012-07-27T13:21:44.646094+02:00 Binding to interface 0.0.0.0 port 53.
2012-07-27T13:21:44.646197+02:00 [error] Cannot bind to socket (98).
2012-07-27T13:21:44.646233+02:00 [error] Could not bind to TCP interface
:: port 53.
2012-07-27T13:21:44.646240+02:00 Binding to interface :: port 53.
Changing interface order the other way around results in listening on v6
only with same error, yet also v4 connections are accepted, probably due
to IPV6_V6ONLY socket option not being turned on by Knot.
When I tried changing listening port on either line, problem
disappeared. I am using Debian package, version 1.0.6-1~bpo60+1.
Cheers,
