6 mararc - Format of the mararc zone file that MaraDNS uses
7
9 Mararc files use a syntax that is a subset of Python 2.2.3 syntax. In
10 particular, Python 2.2.3 (and possibly other versions of Python) can
11 read a properly formatted mararc file without error.
12 Unlike Python, however, a mararc file can only use certain variable
14 names, and the variables can only be declared as described below.
15
17 Comments (lines ignored by the MaraDNS parser) start with the '#'
18 character, like this:
19 # This is a comment
21 The MaraDNS parser also ignores lines which contain only white space.
23
25 The MaraRC file supports two operators: = and +=
26 The = operator can be used to assign both numeric and string values
28 The += operator can only be used on string values, and concatenates the
30 value to the right of the += operator to the string specified to the
31 left of the += operator.
32 Examples:
34 ipv4_bind_addresses = "10.2.19.83"
36 ipv4_bind_addresses += ",10.2.66.74"
37 ipv4_bind_addresses += ",10.3.87.13"
38 ipv4_bind_addresses now has the value
40 "10.2.19.83,10.2.66.74,10.3.87.13"
41 ipv4_alias["icann"] = "198.41.0.4"
43 ipv4_alias["icann"] += ",192.228.79.201"
44 ipv4_alias["icann"] += ",192.33.4.12,128.8.10.90"
45
48 Follows is a listing of variables that can be declared in the mararc
49 file.
50
52 A dictionary variable is an array that can have multiple elements.
53 Unlike a traditional array, these arrays are indexed by strings instead
54 of numbers. These are analogous to associative arrays, or what Perl
55 somewhat inaccurately calls hashes.
56 The syntax of a dictionary variable is in the following form:
58 name["index"] = "value"
60 Where name is the name of the dictionary variable, index is the index
62 of the array, and value is the value stored at that index.
63 Every time we have a dictionary-type variable (such as csv2), we must
65 first initialize it using a line in the following form:
66 csv2 = {}
68 Here, csv2 is the name of the "dictionary" variable that we are
70 initializing.
71
73 Here is a listing of all "dictionary"-style variables that MaraDNS
74 uses:
75 csv2
77 The csv2 dictionary variable stores all of the zone names and file
79 names for the zone files that MaraDNS uses. Note that csv2 files are
80 read after MaraDNS is chrooted. Hence the filename is relative to the
81 chroot_dir. Example:
82 csv2["example.net."] = "db.example.net"
84 See csv2(5) for a description of this file's format.
86 The dictionary index (zone name) can not have a * in it. If it does,
88 MaraDNS will terminate with an "Illegal zone name" error.
89 csv1
91 csv1: Used to indicate the filename to use for a given zone stored in
93 the legacy csv1 zone file format. This is primarily for compatibility
94 with people who have maradns-1.0 zone files.
95 csv1["zone"] = "filename"
97 csv1: A pipe-separated-file. See csv1(5).
99 zone: the zone that file in question is authoritative for
101 filename: the file with the CSV1 zone data
103 Note that csv1 files are read after MaraDNS is chrooted, and, hence the
105 filename is relative to the chroot_dir.
106 See the csv1(5) man page for more information on this file format.
108 ipv4_alias
110 ipv4_alias: Used to give nicknames or aliases for ip/netmask pairs for
112 ipv4 (standard 32-bit) IP addresses.
113 ipv4_alias["name"] = "ip1/netmask,ip2/netmask,etc"
115 name: The name of the alias in question
117 ip: The ip portion of an ip/netmask pair
119 netmask: the mask portion of an ip/netmask pair
121 ,: Used to separate ip/netmask pairs. Spaces may be placed before or
123 after this comma.
124 An ip is in dotted-decimal format, e.g. "10.1.2.3".
126 The netmask can be in one of two formats: A single number between 1 and
128 32, which indicates the number of leading "1" bits in the netmask, or a
129 4-digit dotted-decimal netmask.
130 The netmask is used to specify a range of IPs.
132 ipv4_alias examples
134 10.1.1.1/24 indicates that any ip from 10.1.1.0 to 10.1.1.255 will
136 match.
137 10.1.1.1/255.255.255.0 is identical to 10.1.1.1/24
139 10.2.3.4/16 indicates that any ip from 10.2.0.0 to 10.2.255.255 will
141 match.
142 10.2.3.4/255.255.0.0 is identical to 10.2.3.4/16
144 127.0.0.0/8 indicates that any ip with "127" as the first octet
146 (number) will match.
147 127.0.0.0/255.0.0.0 is identical to 127.0.0.0/8
149 The netmask is optional, and, if not present, indicates that only a
151 single IP will "match". e.g:
152 10.9.9.9/32, 10.9.9.9/255.255.255.255, and 10.9.9.9 are all
154 functionally identical, and indicate that only the ip 10.9.9.9 will
155 match.
156 The significance of "match" depends on what we use the ipv4 alias for.
158 ipv4 aliases can nest. E.g:
160 ipv4_alias["susan"] = "10.6.7.8/24"
162 ipv4_alias["office"] = "susan,10.9.9.9"
163 Where "susan" in the "office" alias matches the value of the ipv4_alias
165 susan.
166 Multiple levels of nesting are allowed. Self-referring nests will
168 result in an error.
169
171 Normal variables. These are variables that can only take a single
172 value.
173 The syntax of a normal variable is in the form
175 name = "value"
177 Where name is the name of the normal variable, and value is the value
179 of the variable in question.
180
182 Here is a listing of normal variables that MaraDNS uses:
183 ipv4_bind_addresses
185 ipv4_bind_addresses: The IP addresses to give the MaraDNS server.
187 This accepts one or more ipv4 IPs in dotted-decimal (e.g. "127.0.0.1")
189 notation, and specifies what IP addresses the MaraDNS server will
190 listen on. Multiple bind addresses are separated with a comma, like
191 this: "10.1.2.3, 10.1.2.4, 127.0.0.1"
192 admin_acl
194 This is a list of ip/netmask pairs that are allowed to get certain
196 administrative information about MaraDNS, including:
197 * The version number of MaraDNS running
199 * The number of threads MaraDNS has
201 * MaraDNS' internal timestamp value
203 Note that this information is not available unless the mararc variable
205 debug_msg_level is sufficiently high. See the information on
206 debug_msg_level below for details on this and on the TXT queries sent
207 to get the above information.
208 bind_address
210 bind_address: The IP address to give the MaraDNS server.
212 This accepts a single IP in dotted-decimal (e.g. "127.0.0.1") notation,
214 and specifies what IP address the MaraDNS server will listen on. Note
215 that ipv4_bind_addresses has the same functionality. This name is
216 included so that old MaraDNS configuration files will continue to work
217 with new MaraDNS releases.
218 bind_star_handling
220 In the case where there is both a star record for a given name and
222 recordtype, a non-star record with the same name but a different
223 recordtype, and no record for the given name and recordtype, MaraDNS
224 will usually return the star record. BIND, on the other hand, will
225 return a "not there" reply. In other words:
226 * If a non-A record for foo.example.com exists
228 * An A record for *.example.com exists
230 * No A record for foo.example.com exists
232 * And the user asks for the A record for foo.example.com
234 * MaraDNS will usually return the A record attached to *.example.com
236 * BIND, on the other hand, returns a "not there" for foo.example.com
238 If the BIND behavior is desired, set bind_star_handling to 1.
240 Otherwise, set this to 0. In MaraDNS 1.3, this has a default value of
241 1.
242 In addition, if there is a star record that could match any given
244 record type, when bind_star_handling is 1, it makes sure that MaraDNS
245 does not incorrectly return a NXDOMAIN (RFC 4074 section 4.2).
246 Also, if bind_star_handling has a value of 2, MaraDNS will handle the
248 following case exactly as per section 4.3.3 of RFC1034:
249 * If a record for foo.example.com exists
251 * An A record for *.example.com exists
253 * And the user asks for the A record for bar.foo.example.com
255 * MaraDNS will usually return the A record attached to *.example.com
257 * RFC1034 section 4.3.3 says one should return a NXDOMAIN.
259 MaraDNS will exit with a fatal error if bind_star_handling has any
261 value besides 0, 1, or 2.
262 chroot_dir
264 chroot_dir: The directory MaraDNS chroots to
266 This accepts a single value: The full path to the directory to use as a
268 chroot jail.
269 Note that csv1 zone files are read after the chroot operation. Hence,
271 the chroot jail needs to have any and all zone files that MaraDNS will
272 load.
273 csv2_default_zonefile
275 This is a special zone file that allows there to be stars at the end of
277 hostnames. This file is similar to a normal csv2 zone file, but has the
278 following features and limitations:
279 * Stars are allowed at the end of hostnames
281 * A SOA record is mandatory
283 * NS records are mandatory
285 * Neither CNAME, FQDN4, nor FQDN6 records are permitted in the zone
287 file
288 * Delegation NS records are not permitted in the zone file
290 * Default zonefiles may not be transferred via zone transfer
292 * Both recursion and default zonefiles may not be enabled at the same
294 time
295 csv2_synthip_list
297 Sometimes the IP list of nameservers will be different than the
299 nameservers one is bound to. This allows the synthetic nameserver list
300 to have different IPs.
301 Note that this may act in an unexpected manner if routable and non-
303 routable (localhost and RFC1918) addresses are combined; in particular,
304 a list with both routable and non-routable addresses will discard the
305 non-routable IP addresses, and a list with rfc1918 and localhost
306 addresses will discard the localhost addresses.
307 csv2_tilde_handling
309 How the csv2 zone file parser handles tildes (the ~ character) in csv2
311 zone files. This is a numeric record, with a possible value between 0
312 and 3 (four possible values). The way the csv2 parser acts at different
313 csv2_tilde_handling levels:
314 * 0) The csv2 parser behaves the same as it does in old MaraDNS
316 releases: The tilde has no special significance to the parser.
317 * 1) A tilde is not allowed anywhere in a csv2 zone file.
319 * 2) A tilde is only allowed between records in a csv2 zone file. If a
321 tilde is between the first record and the second record, a tilde is
322 required to be between all records. Otherwise, a tilde is not allowed
323 anywhere in a csv2 zone file. The first record can not be a TXT, WKS,
324 or LOC record.
325 * 3) A tilde is required to be between all records in a csv2 zone file.
327 The default value for csv2_tilde_handling is 2; this allows
329 compatibility with older zone files without tildes while allowing zone
330 files to be updated to use the tilde to separate resource records.
331 debug_msg_level
333 This is a number indicating what level of information about a running
335 MaraDNS process should be made public. When set to 0, no information
336 will be made public.
337 When set to one (the default), or higher, a Tversion.maradns. (TXT
339 query for "version.maradns.") query will return the version number of
340 MaraDNS.
341 When set to two or higher, a Tnumthreads.maradns. (TXT query for
343 "numthreads.maradns.") query will return the number of threads that
344 MaraDNS is currently running, and a Tcache-elements.maradns. query
345 will return the number of elements in MaraDNS' cache.
346 If MaraDNS is compiled with debugging information on, a
348 Tmemusage.maradns. query will return the amount of memory MaraDNS has
349 allocated. Note that the overhead for tracking memory usage is
350 considerable and that compiling MaraDNS with "make debug" will greatly
351 slow down MaraDNS. A debug build of MaraDNS is not recommended for
352 production use.
353 When set to three or higher, a Ttimestamp.maradns. query will return,
355 in seconds since the UNIX epoch, the timestamp for the system MaraDNS
356 is running on.
357 default_rrany_set
360 This variable used to determine what kind of resource records were
362 returned when an ANY query was sent. In MaraDNS, the data structures
363 have since been revised to return any resource record type when an ANY
364 query is sent; this variable does nothing, and is only here so that old
365 MaraDNS mararc files will continue to work. The only accepted values
366 for this variable were 3 and 15.
367 dns_port
369 This is the port that MaraDNS listens on. This is usually 53 (the
371 default value), but certain unusual MaraDNS setups (such as when
372 resolving dangling CNAME records on but a single IP) may need to have a
373 different value for this.
374 dos_protection_level
376 If this is set to a non-zero value, certain features of MaraDNS will be
378 disabled in order to speed up MaraDNS' response time. This is designed
379 for situations when a MaraDNS server is receiving a large number of
380 queries, such as during a denial of service attack.
381 This is a numeric variable; its default value is zero, indicating that
383 all of MaraDNS' normal features are enabled. Higher numeric values
384 disable more features:
385 * A dos_protection_level between 1 and 78 (inclusive) disables getting
387 MaraDNS status information remotely.
388 * A dos_protection_level of 8 or above disables CNAME lookups.
390 * A dos_protection_level or 12 or above disables delegation NS records.
392 * A dos_protection_level of 14 or above disables ANY record processing.
394 * A dos_protection_level of 18 or above disables star record processing
396 at the beginning of hostnames (default zonefiles still work,
397 however).
398 * A dos_protection_level of 78 disables all authoritative processing,
400 including default zonefiles.
401 The default level of dos_protection_level is 0 when there are one or
403 more zonefiles; 78 when there are no zone files.
404 ipv6_bind_address
406 If MaraDNS is compiled with as an authoritative server, then this
408 variable will tell MaraDNS which ipv6 address for the UDP server to;
409 for this variable to be set, MaraDNS must be bound to at least one ipv4
410 address.
411 hide_disclaimer
413 If this is set to "YES", MaraDNS will not display the legal disclaimer
415 when starting up.
416 long_packet_ipv4
418 This is a list of IPs which we will send UDP packets longer than the
420 512 bytes RFC1035 permits if necessary. This is designed to allow
421 zoneserver, when used send regular DNS packets over TCP, to receive
422 packets with more data than can fit in a 512-byte DNS packet.
423 This variable only functions if MaraDNS is compiled as an authoritative
425 only server.
426 maradns_uid
428 maradns_uid: The numeric UID that MaraDNS will run as
430 This accepts a single numerical value: The UID to run MaraDNS as.
432 MaraDNS, as soon as possible drops root privileges, minimizing the
434 damage a potential attacker can cause should there be a security
435 problem with MaraDNS. This is the UID maradns becomes.
436 The default UID is 99.
438 maradns_gid
440 maradns_gid: The numeric GID that MaraDNS will run as.
442 This accepts a single numerical value: The GID to run MaraDNS as.
444 The default GID is 99.
446 max_ar_chain
448 max_ar_chain: The maximum number of records to display if a record in
450 the additional section (e.g., the IP of a NS server or the ip of a MX
451 exchange) has more than one value.
452 This is similar to max_chain, but applies to records in the
454 "additional" (or AR) section.
455 Due to limitations in the internal data structures that MaraDNS uses to
457 store RRs, if this has a value besides one, round robin rotates of
458 records are disabled.
459 The default value for this variable is 1.
461 max_chain
463 max_chain: The maximum number of records to display in a chain of
465 records.
466 With DNS, it is possible to have more than one RR for a given domain
468 label. For example, "example.com" can have, as the A record, a list of
469 multiple ip addresses.
470 This sets the maximum number of records MaraDNS will show for a single
472 RR.
473 MaraDNS normally round-robin rotates records. Hence, all records for a
475 given DNS label (e.g. "example.com.") will be visible, although not at
476 the same time if there are more records than the value allowed with
477 max_chain
478 The default value for this variable is 8.
480 max_tcp_procs
482 max_tcp_procs: The (optional) maximum number of processes the zone
484 server is allowed to run.
485 Sometimes, it is desirable to have a different number of maximum
487 allowed tcp processes than maximum allowed threads. If this variable is
488 not set, the maximum number of allowed tcp processes is "maxprocs".
489 max_total
491 max_total: The maximum number of records to show total for a given DNS
493 request.
494 This is the maximum total number of records that MaraDNS will make
496 available in a DNS reply.
497 The default value for this variable is 20.
499 max_mem
501 max_mem is the maximum amount of memory we allow MaraDNS to allocate,
503 in bytes.
504 The default value of this is to allocate 1 megabyte for MaraDNS'
506 general use, and in addition, to allocate 1536 bytes for each element
507 we can have in the cache or DNS record that we are authoritatively
508 serving.
509 min_visible_ttl
511 min_visible_ttl: The minimum value that we will will show as the TTL
513 (time to live) value for a resource record to other DNS servers and
514 stub resolvers. In other words, this is the minimum value we will ask
515 other DNS server to cache (keep in their memory) a DNS resource record.
516 The value is in seconds. The default value for this is 30; the minimum
518 value this can have is 5.
519 As an aside, RFC1123 section 6.1.2.1 implies that zero-length TTL
521 records should be passed on with a TTL of zero. This, unfortunately,
522 breaks some stub resolvers (such as Mozilla's stub resolver).
523 remote_admin
525 remote_admin: Whether we allow verbose_level to be changed after
527 MaraDNS is started.
528 If remote_admin is set to 1, and admin_acl is set, any and all IPs
530 listed in admin_acl will be able to reset the value of verbose_level
531 from any value between 0 and 9 via a TXT query in the form of
532 5.verbose_level.maradns. What this will do is set verbose_query to the
533 value in the first digit of the query.
534 This is useful when wishing to temporarily increase the verbose_level
536 to find out why a given host name is not resolving, then decreasing
537 verbose_level so as to minimize the size of MaraDNS' log.
538 synth_soa_origin
540 When a CSV2 zone file doesn't have a SOA record in it, MaraDNS
542 generates a SOA record on the fly. This variable determines the host
543 name for the "SOA origin" (which is called the MNAME in RFC1035); this
544 is the host name of the DNS server which has the "master copy" of a
545 given DNS zone's file.
546 This host name is in human-readable format without a trailing dot,
548 e.g.:
549 synth_soa_origin = "ns1.example.com"
551 If this is not set, a synthetic SOA record will use the name of the
553 zone for the SOA origin (MNAME) field.
554 synth_soa_serial
556 This determines whether we strictly follow RFC1912 section 2.2 with SOA
558 serial numbers. If this is set to 1 (the default value), we do not
559 strictly follow RFC1912 section 2.2 (the serial is a number, based on
560 the timestamp of the zone file, that is updated every six seconds), but
561 this makes it so that a serial number is guaranteed to be automatically
562 updated every time one edits a zone file.
563 If this is set to 2, the SOA serial number will be in YYYYMMDDHH
565 format, where YYYY is the 4-digit year, MM is the 2-digit month, DD is
566 the 2-digit day, and HH is the 2-digit hour of the time the zone file
567 was last updated (GMT; localtime doesn't work in a chroot()
568 environment). While this format is strictly RFC1912 compliant, the
569 disadvantage is that more than one edit to a zone file in an hour will
570 not update the serial number.
571 I strongly recommend, unless it is extremely important to have a DNS
573 zone that generates no warnings when tested at dnsreport.com, to have
574 this set to 1 (the default value). Having this set to 2 can result in
575 updated zone files not being seen by slave DNS servers.
576 Note that synth_soa_serial can only have a value of 1 on the native
578 Windows port.
579 tcp_convert_acl
581 This only applies to the zoneserver (general DNS-over-TCP) program.
583 This is a list of IPs which are allowed to connect to the zoneserver
585 and send normal TCP DNS requests. The zoneserver will convert TCP DNS
586 requests in to UDP DNS requests, and send the UDP request in question
587 to the server specified in tcp_convert_server. Once it gets a reply
588 from the UDP DNS server, it will convert the reply in to a TCP request
589 and send the reply back to the original TCP client.
590 Whether the RD (recursion desired) flag is set or not when converting a
592 TCP DNS request in to a UDP DNS request is determined by whether the
593 TCP client is on the recursive_acl list. Since MaraDNS 2.0 does not
594 have recursion, the maradns daemon ignores the RD bit (Deadwood will
595 not process any queries without the RD bit set).
596 tcp_convert_server
598 This only applies to the zoneserver (general DNS-over-TCP) program.
600 This is the UDP server which we send a query to when converting DNS TCP
602 queries in to DNS UDP servers. Note that, while this value allows
603 multiple IPs, all values except the first one are presently ignored.
604 timestamp_type
606 timestamp_type: The type of timestamp to display. The main purpose of
608 this option is to suppress the output of timestamps. Since duende uses
609 syslog() to output data, and since syslog() adds its own timestamp,
610 this option should be set to 5 when maradns is invoked with the duende
611 tool.
612 This option also allows people who do not use the duende tool to view
614 human-readable timestamps. This option only allows timestamps in GMT,
615 due to issues with showing local times in a chroot() environment.
616 This can have the following values:
618 0 The string "Timestamp" followed by a UNIX timestamp
620 1 Just the bare UNIX timestamp
622 2 A GMT timestamp in the Spanish language
624 3 A (hopefully) local timestamp in the Spanish language
626 4 A timestamp using asctime(gmtime()); usually in the English
628 language
629 5 No timestamp whatsoever is shown (this is the best option when
631 maradns is invoked with the duende tool).
632 6 ISO GMT timestamp is shown
634 7 ISO local timestamp is shown
636 The default value for this variable is 5.
638 verbose_level
640 verbose_level: The number of messages we log to stdout
642 This can have five values:
644 0 No messages except for the legal disclaimer and fatal parsing
646 errors
647 1 Only startup messages logged (Default level)
649 2 Error queries logged
651 3 All queries logged
653 4 All actions adding and removing records from the cache logged
655 The default value for this variable is 1.
657 zone_transfer_acl
659 zone_transfer_acl: List of ips allowed to perform zone transfers with
661 the zone server
662 The format of this string is identical to the format of an ipv4_alias
664 entry.
665
667 # Example mararc file (unabridged version)
668 # The various zones we support
670 # We must initialize the csv2 hash, or MaraDNS will be unable to
672 # load any csv2 zone files
673 csv2 = {}
674 # This is just to show the format of the file
676 #csv2["example.com."] = "db.example.com"

692 # running), unique handling of multiple QDCOUNTs, etc. Some people
693 # might not like these features, so I have added a switch that lets

695 # a value of one here, and MaraDNS should be more or less
696 # indistinguishable from a tinydns server.

735 If one should declare the same the same index twice with a dictionary
736 variable, MaraDNS will exit with a fatal error. This is because earlier
737 versions of MaraDNS acted in a different manner than Python 2.3.3. With
738 Python 2.3.3, the last declaration is used, while MaraDNS used to use
739 the first declaration.
