Almost certainly named -- it appears to listen on a high numbered
UDP port, but all it is is the next /source/ port for an outgoing
UDP packet. You can configure named to always send packets using a
fixed port number (which can be helpful for firewalling) by:
query-source address 12.34.56.78 port 53;
query-source-v6 address 1999:aaaa:bbbb:cccc::1 port 53;
transfer-source 12.34.56.78 port 53;
transfer-source-v6 1999:aaaa:bbbb:cccc::1 port 53;
notify-source 12.34.56.78 port 53;
notify-source-v6 1999:aaaa:bbbb:cccc::1 port 53;
Cheers,
Matthew
