NAME

       zonecheck - DNS zone checking tool

SYNOPSIS

       zonecheck [ -hqV ] [ -voet opt ] [ -46 ] [ -c conf ]
                 [ -n nslist ] [ -s key ] domainname

DESCRIPTION

       The  DNS  is  a critical resource for every network application, quite important to ensure that a zone or
       domain name is correctly configured in the DNS.

       ZoneCheck is intended to help  solving  misconfigurations  or  inconsistencies  usually  revealed  by  an
       increase in the latency of the application, up to the output of unexpected/inconsistant results.

OPTIONS

       NOTE:  It  doesn't  necessary  make sense to combine some options together, if that case happens the most
              recent option will be taken into account, silently discarding the others.

       --lang lang
              Select another language (en, fr, ...). The syntax is the same  as  for  the  environment  variable
              LANG.

       --debug, -d lvl
              Select  the  debugging messages to print or activate debugging code.  This parameter will override
              the value of the environment variable ZC_DEBUG.
              The available options are:
                0x0001 : Initialisation
                0x0002 : Localization / Internationalisation
                0x0004 : Configuration
                0x0008 : Autoconf
                0x0010 : Loading tests
                0x0020 : Tests performed
                0x0040 : Debugging messages from tests
                0x0400 : Information about cached object
                0x0800 : Debugger itself

                0x1000 : Crazy Debug, don't try this at home!
                0x2000 : Dnsruby library debugging messages
                0x4000 : Disable caching
                0x8000 : Don't try to rescue exceptions

       --help, -h
              Show a short description of the different options available in ZoneCheck.

       --version, -V
              Display the version and exit.

       --batch, -B filename
              Depreciated option. You can use this script instead :
                for domain in `cat list_dom`; do
                  echo "Testing $domain"
                  zonecheck $domain
                done

       --config, -c filename
              Specify the location of the configuration file (default is zc.conf).

       --testdir directory
              Location of the directory holding the tests definition.

       --profile, -P profilename
              Force uses of profile profilename.

       --category, -C catlist
              Limit the test to perform to the categories specified by catlist.   The  syntax  for  the  catgory
              description is as follow:
                allow=[+|]    disallow=[-|!]    subcomponent=:    separator=,
                ex: dns:soa,!dns,+
                    don't perform DNS tests that are not SOA related

       --test, -T testname
              testname is the test to perform. In this case failing to pass the test is considered as fatal.

       --testlist
              List all the tests available.

       --testdesc desctype
              Give  a  description  of  the  test,  the possible values for desctype are name, success, failure,
              explanation.

       --resolver, -r resolver
              Resolver to use (only IP address is accepted) for finding the information about the  tested  zone,
              by  default the name servers used are the one specified in /etc/resolv.conf. Note that for finding
              the name servers the zone should already have been delegated.

       --ns, -n nslist
              List of nameservers for the domain. Nameservers name are separated by a semicolon, the name can be
              followed by the equal sign and its IP addresses separated by a colon.
              This can give the following example: ns1;ns2=ip1,ip2;ns3=ip3

       --securedelegation, -s [dsordnskey]
              Force the execution of the full DNSSEC profile. Arguments are optional.  You can precise the Trust
              Anchor of your zone by giving the DNSKEY or the DS and  the  algorithm  used  to  hash  your  key.
              Several  Trust  Anchors  can  be  specified, separated by commas (in that case, they _all_ have to
              match.)
              This can give the following example:
                DNSKEY:af1Bs0F+4rg-g19,DS:eAg7P4J1qfMg:SHA-1
                DS:eAg7P4J1qfMg:SHA-1
                DS-RDATA:5991 8 2 46DB8A99F9125B1F88AAC74DF7EC3FFCCC13CE7412C3BEBB2CB93BED4A05A960
                DNSKEY:af1Bs0F+4rg-g19

       --quiet, -q
              Don't display extra titles.

       --one, -1
              Only display the most relevant message in a compact format.

       --tagonly, -g
              Display only tag. This option should be used for scripting.

       --verbose, -v options
              Display extra information, they can be prefix by '-' or  '!'   to  remove  the  effect,  available
              options are:

              intro, i
                     Print a short summary about the domain name and its nameservers.

       --edns [always|never|auto]
              Activate/Deactivate the use of EDNS for all queries. Three possible values: always,  never,  auto.
              Auto : automatically determine if the domain and the route to name servers can carry EDNS queries.

       --ipv4, -4
              Only check the zone with IPv4 connectivity.

       --ipv6, -6
              Only check the zone with IPv6 connectivity.

       --preset name
              Use of a preset configuration defined in the zc.conf configuration file.

       --option options
              Set extra options. The syntax is: -,-opt,opt,opt=foo

              nojavascript
                     Remove generation of javascript (for HTML output).

ENVIRONMENT

       LANG   Specify the lang and eventually the encoding to use to display messages.  For examples: fr, fr_CA,
              fr.latin1, fr_CA.utf8, ...

       ZC_CONFIG_DIR
              Directory where the configuration file and the different profiles are located.

       ZC_CONFIG_FILE
              Name of the configuration file to use (defaul to zc.conf), it is override by the --config option.

       ZC_LOCALIZATION_DIR
              Directory where all the localization files are located.

       ZC_TEST_DIR
              Directory where all the tests are located, it is override by the --testdir option.

       ZC_HTML_PATH
              Path relative to the web server to use when generating HTML pages.

       ZC_DEBUG
              The variable as the same effect as the debug parameter, but its main advantage is that it is taken
              into account from the beginning of the program.

       ZC_INPUT
              The  variable as the same effect as the undocumented INPUT parameter, it allows to chose the input
              interface used by ZoneCheck, the currently supported values are: cli, cgi  and  inetd.  But  other
              interfaces doesn't accept the same parameters as the one described here.

       ZC_IP_STACK
              Restrict  the IP stack available to IPv4 or IPv6, for that set it respectively to 4 or 6.  This is
              particularly useful if you have an IPv6 stack on your computer but don't have the connectivity, in
              that case define ZC_IP_STACK=4.

       ZC_XML_PARSER
              If  ruby-libxml is installed, this parser will be used instead of rexml for speed improvement, but
              you can force the use of rexml by setting ZC_XML_PARSER to rexml.

       NOTE:  The following variables are mainly useful when  it  is  not  possible  for  the  user  to  specify
              alternative   value   with   the   selected   input   interface:   ZC_CONFIG_DIR,  ZC_CONFIG_FILE,
              ZC_LOCALIZATION_DIR, ZC_TEST_DIR.  Such a case happen when using the cgi interface, and you  don't
              want the user to read an arbitrary configuration file, but as the provider of the service you want
              to use another configuration.

EXIT STATUS

       The following exit status can be reported by ZoneCheck:

       0      Everything went fine, no fatal errors were reported, the domain configuration is correct.

       1      The program completed but some tests failed with a fatal severity, the  domain  is  NOT  correctly
              configured.

       2      The program completed but some tests failed due with a fatal severity due to timeout occuring, the
              domain has been considered as NOT correctly configured, but you could want to check  again  later.
              This is currently not implemented.

       3      The user aborted the program before it's completion.

       4      An  error  which  is  not  directly related to the tests performed has occured (ie: something went
              wrong).

       9      The user (you?) didn't bother reading the man page...

FILES

       /usr/local/etc/zonecheck/zc.conf
              The default configuration file.

       /usr/local/etc/zonecheck/*.profile
              The test sequence to use for different domains.

       /usr/local/libexec/zc/test
              Contains the code of the tests performed by ZoneCheck.

       /usr/local/libexec/zc/locale
              Contains the different translations.

       /usr/local/libexec/zc/www
              Contains a website sample for the web interface.

EXAMPLES

       Test the domain_name with IPv6 only connectivity, print a summary information about the tested domain  as
       well as explanations and details of failed tests.
              zonecheck -6 --verbose=i,x,d domain_name

       Ask for the 'error' message associated with the test 'soa'.
              zonecheck --testdesc error -T soa

       Only  print  tests  which  have  failed  and  the result (succeed/failed), this would be ideal for giving
       people, through email fir example, a short description of why their domains are not correctly configured.
              zonecheck -q -vn,d,x,f domain_name

       If you want to test your domain, you will certainly like to use these parameters (the use of IPv4 only as
       been  forced because now people have computer with IPv6 stack but very few have the IPv6 connectivity, so
       autodetection will failed).
              zonecheck -4 -vi,x,d,c domain_name

AUTHORS

       Stephane D'Alu with the help of people working at AFNIC is the author of this version, but  don't  forget
       also to take a look at the CREDITS file available in the distribution.

HISTORY

       ZoneCheck  was  initiated and developed by engineers working at NIC France (INRIA's service) to check the
       correct configuration of a zone before delegating a domain name under .fr. Its development  continued  at
       AFNIC, which took over the activities of NIC France on January 1 1998.

       ZoneCheck-1.*  was  created  in  1995  by  Benoit  Grange  and has been maintained by him until 1997. The
       prototype was a script using the dig command, which evolved into a perl program based on the DNS resolver
       Resolv5.  Vincent Gillet maintained the programme in 1998. This task has been taken over by Erwan Mas and
       Philippe Lubrano from 1998 until now.

       ZoneCheck-2.* is a rewrite from scratch done in ruby at the end of 2002  by  Stephane  D'Alu,  so  as  to
       create a modular and extensible version. And is the current version of ZoneCheck.
