6 zoneserver - handle zone transfers and other TCP functions for MaraDNS
7
9 zoneserver listens on port 53/tcp and handles DNS zone transfers and
10 any DNS query done over TCP instead of UDP. zoneserver uses a
11 configuration file, /etc/mararc by default, to determine its
12 parameters.
13
15 zoneserver -f pointer_to_mararc_file
16
18 -f Specifies the location of the configuration file. MaraDNS uses the
19 same configuration file for both the main dns server and the
20 zoneserver.
21
23 The file format for the mararc file can be found in the mararc(5)
24 manual page. In particular, the zoneserver uses the zone_transfer_acl,
25 tcp_convert_acl, tcp_convert_server, bind_address, and recursive_acl
26 mararc parameters.
27
29 In this example mararc file, which is used both by maradns and
30 zoneserver, we allow 10.1.2.3, 10.1.14.7, and 192.168.116.{any} to
31 transfer zones, and we allow anyone on the internet to perform TCP
32 queries. The only zone served in this example is example.com:
33 ipv4_bind_addresses = "10.1.1.1" # Our IP
35 tcp_convert_server = "10.1.1.1" # IP of UDP DNS server
36 tcp_convert_acl = "0.0.0.0/0" # Anyone may do DNS-over-TCP
37 chroot_dir = "/etc/maradns" # Where zone files are
38 csv2 = {} # Initialize list of zone files
39 csv2["example.com."] = "db.example.com" # example.com zone file
40 # The next line is a list of who can transfer zones from us
41 zone_transfer_acl = "10.1.2.3, 10.1.14.7, 192,168.116.0/24"

50 zoneserver assumes that the authoritative NS records are immediately
51 after the SOA record, and that there is at least one non-NS between
52 that last authority NS record for the zone and the first delegation NS
53 record.
54 IXFR requests are incremental zone transfers, meaning that the DNS
56 server should only display records changed since the last IXFR request.
57 zoneserver, however, treats an IXFR as if it were an AXFR request,
58 outputting all of the records for the zone in question.
59 zoneserver closes the TCP connection after transferring the requested
61 zone.
62 If an unauthorized client attempts to connect to the zoneserver,
64 zoneserver immediately disconnects the unauthorized client.
