NAME

6       zoneserver - handle zone transfers and other TCP functions for MaraDNS
7

DESCRIPTION

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

USAGE

15       zoneserver -f pointer_to_mararc_file
16

OPTIONS

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

CONFIGURATION FILE FORMAT

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, and bind_address mararc
26       parameters.
27

EXAMPLE MARARC FILE

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
34       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"

BUGS

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