Hello,
I have setup a KNOT dns server but I'm having troubles with the UDP
queries. The server is not answering to the UDP queries but it is
answering to queries in TCP.
The server is running on a CentOS release 6.3 (Final) and the
configuration file is the following.
*************knot.conf***********
system {
identity "Yet.another.server";
nsid "Yet.another.server";
storage "/opt/knot_run/knot-minimal";
pidfile "/opt/knot_run/knot.pid";
user root;
}
interfaces {
ipv4 { address 127.0.0.1@53; }
ipv4 { address 193.137.197.25@53; }
}
remotes {
ns-test01 { address 193.136.192.86@53; }
ns-test02 { address 193.136.192.87@53; }
ns-test03 { address 193.137.196.30@53; }
ns-test04 { address 193.137.196.31@53; }
}
zones {
zonetest-01.dns.pt {
file "/opt/knot_run/zones/zonetest01";
xfr-in ns-test01;
notify-in ns-test01;
}
zonetest-06.dns.pt {
file "/opt/knot_run/zones/zonetest06";
}
}
log {
file "/opt/knot_run/log/knot.log" { any all; }
}
**********************************
The output of the log file is
