A list of all the commands +needed to build everything can be found in README.git. Note that the actual +commands may be a little bit different on your machine.

Jakob Schlyter has kindly contributed a build +script that sets the right build and link options. You can find it in +contrib/build-solaris.sh + +KNOWN ISSUES + +A complete list of currently known open issues can be found here: +http://www.nlnetlabs.nl/projects/ldns/bugs + +* pyldns +Compiling pyldns produces many ``unused parameter'' warnings. Those are +harmless and may safely be ignored. +Also, when building with SWIG older than 2.0.4, compiling +pyldns produces many ``missing initializer'' warnings.

Don't override it +# in your configure.ac. +# +# This macro checks for Python and tries to get the include path to +# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) +# output variables. It also exports $(PYTHON_EXTRA_LIBS) and +# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. +# +# You can search for some particular version of Python by passing a +# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please +# note that you *have* to pass also an operator along with the version to +# match, and pay special attention to the single quotes surrounding the +# version number. Don't use "PYTHON_VERSION" for this: that environment +# variable is declared as precious and thus reserved for the end-user. +# +# This macro should work for all versions of Python >= 2.1.0.

If SWIG is +# found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd. +# +# You can use the optional first argument to check if the version of the +# available SWIG is greater than or equal to the value of the argument. It +# should have the format: N[.N[.N]] (N is a number between 0 and 999. Only +# the first N is mandatory.) If the version argument is given (e.g. +# 1.3.17), AX_PKG_SWIG checks that the swig package is this version number +# or higher. +# +# As usual, action-if-found is executed if SWIG is found, otherwise +# action-if-not-found is executed. +# +# In configure.in, use as: +# +# AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ]) +# AX_SWIG_ENABLE_CXX +# AX_SWIG_MULTI_MODULE_SUPPORT +# AX_SWIG_PYTHON +# +# LICENSE +# +# Copyright (c) 2008 Sebastian Huber +# Copyright (c) 2008 Alan W.

You may also read the documentation of the ldns library +(http://www.nlnetlabs.nl/projects/ldns). + +=head2 Brief examples of usage + + use DNS::LDNS ':all'; + + my $z = new DNS::LDNS::Zone(filename => '/path/to/myzone'); + print DNS::LDNS::last_error; + my $rr = new DNS::LDNS::RR('mylabel 3600 IN A 168.10.10.10'); + print $z->soa->to_string; + my $rrlist = $z->rrs->push($rr); + print $z->to_string; + + my $kl = new DNS::LDNS::KeyList; + $kl->push(new DNS::LDNS::Key(filename => 'key'); + $kl->key(0)->set_pubkey_owner( + new DNS::LDNS::RData(LDNS_RDF_TYPE_DNAME, 'myzone.org')); + my $signedz = $z->sign($kl); + print $signedz->to_string; + + my $r = new DNS::LDNS::Resolver(filename => '/my/resolv.conf'); + my $p = $r->send( + new DNS::LDNS::RData(LDNS_RDF_TYPE_DNAME, 'www.google.com'), + LDNS_RR_TYPE_A, LDNS_RR_CLASS_IN, LDNS_RD); + print $p->answer->to_string; + print $p->authority->to_string; + +=head2 Classes + +A description of the classes included and how they map to the ldns +library structures: + +=over 20 + +=item B + +Base class with static functions and constants + +=item B + +Represents a parsed zonefile (maps to the ldns_zone struct) + +=item B + +Represents a list of RRs. This class is also used to represent an +RRSet if all the dnames and types are equal, (maps to the the +ldns_rr_list struct) + +=item B + +Represents a resource record (RR), (maps to the ldns_rr struct) + +=item B + +Represents an rdata field or a dname in an RR (maps to the ldns_rdf +struct) + +=item B + +Represents a DNS resolver (maps to the ldns_resolver struct) + +=item B + +Represents a DNS package (maps to the ldns_pkt struct) + +=item B + +Represents a DNSSec private key (maps to the ldns_key struct) + +=item B + +Represents a linked list of keys (maps to the ldns_key_list struct) + +=item B + +Represents a zone with dnssec data (maps to the ldns_dnssec_zone +struct) + +=item B + +Represents a tree of DNSSecName nodes (maps to the ldns_rbtree struct) + +=item B + +Represents a node in the RBTree (maps to the ldns_rbnode struct) + +=item B + +Represents a dname in a DNSSecZone and holds a DNSSecRRSets list for +this dname, possibly with signatures (maps to the ldns_dnssec_name +struct) + +=item B + +Represents a linked list of DNSSec RR sets, possibly with signatures +(maps to the ldns_dnssec_rrsets struct) + +=item B + +Represents a linked list of RRs (maps to the ldns_dnssec_rrs struct) + +=item B + +Represents a chain of RR, DNSKEY, and DS data used for building a +dnssec trust tree (maps to the ldns_dnssec_data_chain struct) + +=item B + +Represents a tree of chained trust relationships from a signed RR to a +set of trust anchors (maps to the ldns_dnssec_trust_tree struct). + +=item B + +Garbage collector. Handles ownership dependencies and freeing data +used by the other classes. Used internally only. + +=back + +One thing to note is that some of the classes have a seemingly +overlapping functionality. The Zone and RRList are used to represent +a generic zone. It may contain dnssec data but treats it like any +other dns data and does not have any knowledge of its structure. The +DNSSec* and RB* classes are building blocks for representing a signed +zone in a more structured way. + +=head2 Static functions + + str = rr_type2str(type) + str = rr_class2str(class) + type = rr_type_by_name(str) + class = rr_class_by_name(str) + str = pkt_opcode2str(opcode) + str = pkt_rcode2str(rcode) + error = errorstr_by_id(status) + str = DNS::LDNS::last_error + status = DNS::LDNS::last_status + rr = dnssec_create_nsec(from, to, type) + rr = dnssec_create_nsec3(from, to, algorithm, flags, iterations, salt) + rr = create_nsec(current, next, rrs) + rr = create_nsec3(cur_owner, cur_zone, algorithm, flags, + iterations, salt, empty_nonterminals) + algo = signing_algorithm_by_name(name) + bool = key_algorithm_supported(algorithm) + rr = read_anchor_file(filename) + +=head2 Object references and cloning + +Since some of the objects are found as sub objects within other +objects, it is important to know how the wrapper classes handle +object references, dependencies and cloning. The general rule is that +accessor methods just return a reference to the object while methods +inserting data inserts inserts a clone of the object. Most classes +have a clone method which can be used if a cloned object is what you +really want. + +=head3 Examples + +DNS::LDNS::Zone::rrs returns a reference to the DNS::LDNS::RRList +within the zone, so if you make changes to the RRList you also +changes the Zone object. + +DNS::LDNS::RRList::push(rr) clones the rr, then pushes the cloned rr +to the list. Changing the rr afterwards will not change the list. + +An exception is the Key class which does not have a clone +mechanism. In this case we allow a free Key to be added to only one +KeyList. Adding it to multiple lists will provoke an error. + +The wrapper keeps track of allocated data structures and references. +Whenever data is no longer referred to by a perl object, it will be +freed. + +=head2 ERROR HANDLING + +The purpose for writing this wrapper class has been to be able to +process zone file data with good time performance. Data checking and +error handling is a bit sparse. + +Most constructors will update the DNS::LDNS::last_status variable if +they fail (return undef). Wrapper methods to ldns functions which would +return a status will update the static DNS::LDNS::last_status variable. +Most methods do not return a status and will not reset this variable +even though they succeeds. + +=head2 EXPORT + +None by default. + +=head2 Exportable constants + +=head3 Status + + LDNS_STATUS_ADDRESS_ERR + LDNS_STATUS_CERT_BAD_ALGORITHM +

Use + + perl ppport.h --list-provided + +to see which API elements are provided by ppport.h. + +=item * + +You should avoid using deprecated parts of the API. For example, using +global Perl variables without the C prefix is deprecated. Also, +some API functions used to have a C prefix. Using this form is +also deprecated. You can safely use the supported API, as F +will provide wrappers for older Perl versions. + +=item * + +If you use one of a few functions or variables that were not present in +earlier versions of Perl, and that can't be provided using a macro, you +have to explicitly request support for these functions by adding one or +more C<#define>s in your source code before the inclusion of F. + +These functions or variables will be marked C in the list shown +by C<--list-provided>. + +Depending on whether you module has a single or multiple files that +use such functions or variables, you want either C or global +variants. + +For a C function or variable (used only in a single source +file), use: + + #define NEED_function + #define NEED_variable + +For a global function or variable (used in multiple source files), +use: + + #define NEED_function_GLOBAL + #define NEED_variable_GLOBAL + +Note that you mustn't have more than one global request for the +same function or variable in your project. + + Function / Variable Static Request Global Request + ----------------------------------------------------------------------------------------- + PL_parser NEED_PL_parser NEED_PL_parser_GLOBAL + PL_signals NEED_PL_signals NEED_PL_signals_GLOBAL + eval_pv() NEED_eval_pv NEED_eval_pv_GLOBAL + grok_bin() NEED_grok_bin NEED_grok_bin_GLOBAL + grok_hex() NEED_grok_hex NEED_grok_hex_GLOBAL + grok_number() NEED_grok_number NEED_grok_number_GLOBAL + grok_numeric_radix() NEED_grok_numeric_radix NEED_grok_numeric_radix_GLOBAL + grok_oct() NEED_grok_oct NEED_grok_oct_GLOBAL + load_module() NEED_load_module NEED_load_module_GLOBAL + my_snprintf() NEED_my_snprintf NEED_my_snprintf_GLOBAL + my_sprintf() NEED_my_sprintf NEED_my_sprintf_GLOBAL + my_strlcat() NEED_my_strlcat NEED_my_strlcat_GLOBAL + my_strlcpy() NEED_my_strlcpy NEED_my_strlcpy_GLOBAL + newCONSTSUB() NEED_newCONSTSUB NEED_newCONSTSUB_GLOBAL + newRV_noinc() NEED_newRV_noinc NEED_newRV_noinc_GLOBAL + newSV_type() NEED_newSV_type NEED_newSV_type_GLOBAL + newSVpvn_flags() NEED_newSVpvn_flags NEED_newSVpvn_flags_GLOBAL + newSVpvn_share() NEED_newSVpvn_share NEED_newSVpvn_share_GLOBAL + pv_display() NEED_pv_display NEED_pv_display_GLOBAL + pv_escape() NEED_pv_escape NEED_pv_escape_GLOBAL + pv_pretty() NEED_pv_pretty NEED_pv_pretty_GLOBAL + sv_2pv_flags() NEED_sv_2pv_flags NEED_sv_2pv_flags_GLOBAL + sv_2pvbyte() NEED_sv_2pvbyte NEED_sv_2pvbyte_GLOBAL + sv_catpvf_mg() NEED_sv_catpvf_mg NEED_sv_catpvf_mg_GLOBAL + sv_catpvf_mg_nocontext() NEED_sv_catpvf_mg_nocontext NEED_sv_catpvf_mg_nocontext_GLOBAL + sv_pvn_force_flags() NEED_sv_pvn_force_flags NEED_sv_pvn_force_flags_GLOBAL + sv_setpvf_mg() NEED_sv_setpvf_mg NEED_sv_setpvf_mg_GLOBAL + sv_setpvf_mg_nocontext() NEED_sv_setpvf_mg_nocontext NEED_sv_setpvf_mg_nocontext_GLOBAL + vload_module() NEED_vload_module NEED_vload_module_GLOBAL + vnewSVpvf() NEED_vnewSVpvf NEED_vnewSVpvf_GLOBAL + warner() NEED_warner NEED_warner_GLOBAL + +To avoid namespace conflicts, you can change the namespace of the +explicitly exported functions / variables using the C +macro.

Simply say: + + perl ppport.h + +The result will usually be a list of patches suggesting changes +that should at least be acceptable, if not necessarily the most +efficient solution, or a fix for all possible problems. + +If you know that your XS module uses features only available in +newer Perl releases, if you're aware that it uses C++ comments, +and if you want all suggestions as a single patch file, you could +use something like this: + + perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff + +If you only want your code to be scanned without any suggestions +for changes, use: + + perl ppport.h --nochanges + +You can specify a different C program or options, using +the C<--diff> option: + + perl ppport.h --diff='diff -C 10' + +This would output context diffs with 10 lines of context. + +If you want to create patched copies of your files instead, use: + + perl ppport.h --copy=.new + +To display portability information for the C function, +use: + + perl ppport.h --api-info=newSVpvn + +Since the argument to C<--api-info> can be a regular expression, +you can use + + perl ppport.h --api-info=/_nomg$/ + +to display portability information for all C<_nomg> functions or + + perl ppport.h --api-info=/./ + +to display information for all known API elements. + +=head1 BUGS + +If this version of F is causing failure during +the compilation of this module, please check if newer versions +of either this module or C are available on CPAN +before sending a bug report. + +If F was generated using the latest version of +C and is causing failure of this module, please +file a bug report using the CPAN Request Tracker at L. + +Please include the following information: + +=over 4 + +=item 1. + +The complete output from running "perl -V" + +=item 2. + +This file. + +=item 3. + +The name and version of the module you were trying to build. + +=item 4. + +A full log of the build that failed. + +=item 5. + +Any other information that you think could be relevant. + +=back + +For the latest version of this code, please get the C +module from CPAN. + +=head1 COPYRIGHT + +Version 3.x, Copyright (c) 2004-2009, Marcus Holland-Moritz. + +Version 2.x, Copyright (C) 2001, Paul Marquess. + +Version 1.x, Copyright (C) 1999, Kenneth Albanowski. + +This program is free software; you can redistribute it and/or +modify it under the same terms as Perl itself. + +=head1 SEE ALSO + +See L. + +=cut + +use strict; + +# Disable broken TRIE-optimization +BEGIN { eval '${^RE_TRIE_MAXBUF} = -1' if $] >= 5.009004 && $] <= 5.009005 } + +my $VERSION = 3.19; + +my %opt = ( + quiet => 0, + diag => 1, + hints => 1, + changes => 1, + cplusplus => 0, + filter => 1, + strip => 0, + version => 0, +); + +my($ppport) = $0 =~ /([\w.]+)$/; +my $LF = '(?:\r\n|[\r\n])'; # line feed +my $HS = "[ \t]"; # horizontal whitespace + +# Never use C comments in this file! +my $ccs = '/'.'*'; +my $cce = '*'.'/'; +my $rccs = quotemeta $ccs; +my $rcce = quotemeta $cce; + +eval { + require Getopt::Long; + Getopt::Long::GetOptions(\%opt, qw( + help quiet diag! filter! hints! changes! cplusplus strip version + patch=s copy=s diff=s compat-version=s + list-provided list-unsupported api-info=s + )) or usage(); +}; + +if ($@ and grep /^-/, @ARGV) { + usage() if "@ARGV" =~ /^--?h(?:elp)?$/; + die "Getopt::Long not found.

+ +The rdf structure, the RData Field, is a type that contains the different +types in the rdata of an RR. Consider the following example: + +example.com. IN MX 10 mx.example.com. + +The "10 mx.example.com." is the rdata in this case. It consists of two +fields, "10" and "mx.example.com".

It is specificly designed to be used with DNSSEC. +.PP +The name \fBdrill\fR is a pun on \fBdig\fR. With \fBdrill\fR you should be able +get even more information than with \fBdig\fR. +.PP +If no arguments are given class defaults to 'IN' and type to 'A'. The +server(s) specified in /etc/resolv.conf are used to query against. + +.PP +\fIname\fR +Ask for this name. + +.PP +\fI@server\fR +Send to query to this server. If not specified use the nameservers from +\fI/etc/resolv.conf\fR. + +.PP +\fItype\fR +Ask for this RR type. If type is not given on the command line it defaults +to 'A'. Except when doing a reverse lookup when it defaults to 'PTR'. + +.PP +\fIclass\fR +Use this class when querying. + +.SH SAMPLE USAGE +\fBdrill mx miek.nl\fR +Show the MX records of the domain miek.nl + +.TP +\fBdrill \-S jelte.nlnetlabs.nl\fR +Chase any signatures in the jelte.nlnetlab.nl domain. This option is +only available when ldns has been compiled with openssl-support. + +.TP +\fBdrill \-TD www.example.com\fR +Do a DNSSEC (\-D) trace (\-T) from the rootservers down to www.example.com. +This option only works when ldns has been compiled with openssl support. + +.TP +\fBdrill \-s dnskey jelte.nlnetlabs.nl\fR +Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found DNSKEY +record also print the DS record. + +.SH OPTIONS + +.TP +\fB\-D +Enable DNSSEC in the query. When querying for DNSSEC types (DNSKEY, RRSIG, +DS and NSEC) this is \fInot\fR automatically enabled. + +.TP +\fB\-T +Trace \fIname\fR from the root down. When using this option the @server +arguments is not used. + +.TP +\fB\-S +Chase the signature(s) of 'name' to a known key or as high up in +the tree as possible. + +.TP +\fB\-I \fIIPv4 or IPv6 address\fR +Source address to query from. The source address has to be present +on an interface of the host running drill. + +.TP +\fB\-V \fIlevel\fR +Be more verbose. Set level to 5 to see the actual query that is sent. + +.TP +\fB\-Q +Quiet mode, this overrules \-V. + +.TP +\fB\-f \fIfile\fR +Read the query from a file. The query must be dumped with \-w. + +.TP +\fB\-i \fIfile\fR +read the answer from the file instead from the network. This aids +in debugging and can be used to check if a query on disk is valid. +If the file contains binary data it is assumed to be a query in +network order. + +.TP +\fB\-w \fIfile\fR +Write an answer packet to file. + +.TP +\fB\-q \fIfile\fR +Write the query packet to file. + +.TP +\fB\-v +Show drill's version. + +.TP +\fB\-h +Show a short help message. + +.SS QUERY OPTIONS + +.TP +\fB\-4 +Stay on ip4. Only send queries to ip4 enabled nameservers. + +.TP +\fB\-6 +Stay on ip6. Only send queries to ip6 enabled nameservers. + +.TP +\fB\-a +Use the resolver structure's fallback mechanism if the answer +is truncated (TC=1). If a truncated packet is received and this +option is set, drill will first send a new query with EDNS0 +buffer size 4096. + +If the EDNS0 buffer size was already set to 512+ bytes, or the +above retry also results in a truncated answer, the resolver +structure will fall back to TCP. + +.TP +\fB\-b \fIsize\fR +Use size as the buffer size in the EDNS0 pseudo RR. + +.TP +\fB\-c \fIfile\fR +Use file instead of /etc/resolv.conf for nameserver configuration. + +.TP +\fB\-d \fIdomain\fR +When tracing (\-T), start from this domain instead of the root. + +.TP +\fB\-t +Use TCP/IP when querying a server + +.TP +\fB\-k \fIkeyfile\fR +Use this file to read a (trusted) key from. When this options is +given \fBdrill\fR tries to validate the current answer with this +key. No chasing is done. When \fBdrill\fR is doing a secure trace, this +key will be used as trust anchor. Can contain a DNSKEY or a DS record. + +Alternatively, when DNSSEC enabled tracing (\fB-TD\fR) or signature +chasing (\fB-S\fR), if \fB-k\fR is not specified, and a default trust anchor +(@LDNS_TRUST_ANCHOR_FILE@) exists and contains a valid DNSKEY or DS record, +it will be used as the trust anchor. + +.TP +\fB\-o \fImnemonic\fR +Use this option to set or unset specific header bits. A bit is +set by using the bit mnemonic in CAPITAL letters. A bit is unset when +the mnemonic is given in lowercase. The following mnemonics are +understood by \fBdrill\fR: + + QR, qr: set, unset QueRy (default: on) + AA, aa: set, unset Authoritative Answer (default: off) + TC, tc: set, unset TrunCated (default: off) + RD, rd: set, unset Recursion Desired (default: on) + CD, cd: set, unset Checking Disabled (default: off) + RA, ra: set, unset Recursion Available (default: off) + AD, ad: set, unset Authenticated Data (default: off) + +Thus: \fB-o CD\fR, will enable Checking Disabled, which instructs the +cache to not validate the answers it gives out. + +.TP +\fB\-p \fIport\fR +Use this port instead of the default of 53. + +.TP +\fB\-r \fIfile\fR +When tracing (\-T), use file as a root servers hint file. + +.TP +\fB\-s +When encountering a DNSKEY print the equivalent DS also. + +.TP +\fB\-u +Use UDP when querying a server. This is the default. + +.TP +\fB\-w \fIfile\fR +write the answer to a file. The file will contain a hexadecimal dump +of the query. This can be used in conjunction with \-f. + +.TP +\fB\-x +Do a reverse lookup. The type argument is not used, it is preset to PTR. + +.TP +\fB\-y \fI\fR +specify named base64 tsig key, and optional an algorithm (defaults to hmac-md5.sig-alg.reg.int) + +.TP +\fB\-z \fR +don't randomize the nameserver list before sending queries. + +.SH "EXIT STATUS" +The exit status is 0 if the looked up answer is secure and trusted, +or insecure. +The exit status is not 0 if the looked up answer is untrusted or bogus, +or an error occurred while performing the lookup. + +.SH "FILES" +.TP +@LDNS_TRUST_ANCHOR_FILE@ +The file from which trusted keys are loaded when no \fB-k\fR option is given. +.SH "SEE ALSO" +.LP +unbound-anchor(8) + +.SH AUTHOR +Jelte Jansen and Miek Gieben.

When run it +will create a new zonefile that contains RRSIG and NSEC resource records, as +specified in RFC 4033, RFC 4034 and RFC 4035. + +Keys must be specified by their base name (i.e. without .private). If +the DNSKEY that belongs to the key in the .private file is not present +in the zone, it will be read from the file .key. If that +file does not exist, the DNSKEY value will be generated from the +private key. + +Multiple keys can be specified, Key Signing Keys are used as such when +they are either already present in the zone, or specified in a .key +file, and have the KSK bit set. + +.SH OPTIONS +.TP +\fB-b\fR +Augments the zone and the RR's with extra comment texts for a more readable +layout, easier to debug. DS records will have a bubblebabble version of +the data in the comment text, NSEC3 records will have the original NSEC3 +in the comment text. + +Without this option, only DNSKEY RR's will have their Key Tag annotated in +the comment text. + +.TP +\fB-d\fR +Normally, if the DNSKEY RR for a key that is used to sign the zone is +not found in the zone file, it will be read from .key, or derived from +the private key (in that order). This option turns that feature off, +so that only the signatures are added to the zone. + +.TP +\fB-e\fR \fIdate\fR +Set expiration date of the signatures to this date, the format can be +YYYYMMDD[hhmmss], or a timestamp. + +.TP +\fB-f\fR \fIfile\fR +Use this file to store the signed zone in (default .signed) + +.TP +\fB-i\fR \fIdate\fR +Set inception date of the signatures to this date, the format can be +YYYYMMDD[hhmmss], or a timestamp. + +.TP +\fB-o\fR \fIorigin\fR +Use this as the origin of the zone + +.TP +\fB-v\fR +Print the version and exit + +.TP +\fB-A\fR +Sign the DNSKEY record with all keys. By default it is signed with a +minimal number of keys, to keep the response size for the DNSKEY query +small, and only the SEP keys that are passed are used. If there are no +SEP keys, the DNSKEY RRset is signed with the non\-SEP keys. This option +turns off the default and all keys are used to sign the DNSKEY RRset. + +.TP +\fB-E\fR \fIname\fR +Use the EVP cryptographic engine with the given name for signing. This +can have some extra options; see ENGINE OPTIONS for more information. + +.TP +\fB-k\fR \fIid,int\fR +Use the key with the given id as the signing key for algorithm int as +a Zone signing key. This option is used when you use an OpenSSL +engine, see ENGINE OPTIONS for more information. + +.TP +\fB-K\fR \fIid,int\fR + +Use the key with the given id as the signing key for algorithm int as +a Key signing key. This options is used when you use an OpenSSL engine, +see ENGINE OPTIONS for more information. + +.TP +\fB-n\fR +Use NSEC3 instead of NSEC. + +.TP +If you use NSEC3, you can specify the following extra options: + +.TP +\fB-a\fR \fIalgorithm\fR +Algorithm used to create the hashed NSEC3 owner names + +.TP +\fB-p\fR +Opt-out.

This is done through the environment +variable OPENSSL_CONF. If you use \-E with a non-existent engine name, +ldns-signzone will print a list of engines supported by your +configuration. + +The key options (\-k and \-K) work as follows; you specify a key id, and a DNSSEC algorithm number (for instance, 5 for RSASHA1). The key id can be any of the following: + + + : + id_ + slot_-id_ + label_
