DESCRIPTION
       inadyn-mt  is  a	client for `open' name servers.	That is, it allows the
       user's machine to have an internet recognized name by transferring some
       control	over  a	 name server not managed by the	user. Some of the ser-
       vices that are offered by those open name servers are free  of  charge,
       and  work even when the client machine does not have a static IP.  Sup-
       ports both IPv4,	and IPv6 addresses.

       Supported name servers are:

       Its basic operation is to periodically check whether the	actual	IP  of
       the client machine is the same one that is recorded in the name server,
       and update the name server records when there is	a mismatch.

       For IPv6	addresses, see below, alias, and ip_server_name	options.

       Also, network status can	be checked at a	user specified	interval,  and
       audible alerts issued in	event of network status	down.

   OPTIONS
       -h, --help
	      Print a summary of the options to	inadyn-mt and exit.

       -u, --username username
	      The username, if applicable. This	might be referred to as	hash.

       -p, --password password
	      The password, if applicable.

       -a,  --alias alias[, hash] [ip type] [if] [addr pref] [ip server[:port]
       <ip server url> [ip server host]]
	      A	host name alias, optional comma	delimited hash,	 and  optional
	      ip  version  (default  auto), network interface, address prefer-
	      ence, ip server (and optional colon delimited port) and url,  ip
	      server host. This	option can appear multiple times.

	      IP  types	are dual, coupled, ip4,	ip6, or	auto.  IP type auto is
	      the default.  IP type dual (for  dual  ip	 stack),  denotes  the
	      alias  should  be	 updated  to both ipv6,	ipv4.  Coupled is like
	      dual, but	denotes	DDNS server accepts dual stack	updates	 in  a
	      single  request, where the ipv4, ipv6 addresses are presented as
	      a	comma delimited	list.

	      Network interface	parameter should denote	the network  interface
	      to  be  used as the ip server connect source address.  When this
	      parameter	is opted, unless ip type is ip4, the alias will	be up-
	      dated  to	 the  ipv6 address obtained from this interface, along
	      with, if indicated, the ipv4 address obtained from ip server.

	      The addr pref parameter denotes ipv6 privacy extentions  address
	      preference.   It can be one of either pub, policy, home, careof,
	      crypto, nocrypto,	tmp, pubtmp.  Logical OR  not  yet  supported.
	      The default is pub.

	      Use  the ip server parameter for other than the DDNS server's ip
	      server as	per default inadyn-mt hard  coded  configuration  set-
	      tings.  It can include a colon delimted port number.  It must be
	      accompanied by a url parameter.  Finally,	an ip server host  can
	      be  designated - useful in case of ip server running on multiple
	      server hosts, or the ip server domain name  used	to  reach  the
	      server otherwise differs from actual ip server domain name.

	      Except  the  host	(alias)	parameter, all of these	parameters are
	      optional,	but order matters.

       --input_file file
	      The file name that contains inadyn-mt command options exactly as
	      specified	 in  the  command  line	 syntax	(adds to those already
	      present in the cmd line).	The default configuration file name is
	      '/etc/inadyn-mt.conf'.  It is looked at automatically if inadyn-
	      mt is called without any command line options. The format	is  as
	      expected for a **NIX config   the	hash character is used to com-
	      ment entire lines. Spaces	are ingored. The long options  may  be
	      specified	without	-- if placed at	the beginning of the line.

       --ip_server_name	server[:port] url
	      The   client   IP	  is  detected	by  calling  'url'  from  this
	      'server:port'.

	      Choice of	ip server name parameter  option  can  determine  what
	      type  of	address	is updated.  To	update an IPv6 address,	simply
	      choose an	ip server that	supports  IPv6,	 such  as,  ip6.me  /,
	      myip.dk  /,  dhis.org  /,	among others.  And, of course, dynamic
	      dns server should	be set to one that supports IPv6.

       --ip_server_host	hostname
	      Host name	used in	http request to	ip server if different from ip
	      server name, as when, e.g., ip_server_name is 'localhost:port /'
	      through an SSL bridge. Defaults to ip server name.

       --dyndns_server_name server[:port]
	      The server that receives the update DNS requests.	When no	 proxy
	      is  specified  it	is sufficient to set the dyndns_system so that
	      the default servers will be taken.  The  option  is  useful  for
	      generic DynDNS services that support HTTP	update.

       --dyndns_server_url url
	      The update path inside the DynDNS	server.

       --dyndns_server_host hostname
	      Host  name  used	in  http update	DNS request, if	different from
	      dyndns server name, as when,  e.g.,  ip_server_name  is  'local-
	      host:port'  through  an  SLL  bridge.  Defaults to dyndns	server
	      name.

       --dyndns_system system
	      An optional DDNS service (dyndns@dyndns.org is the default). For

	      http://www.dyndns.org

	      the  acceptable  services	 are  one  of	dyndns@dyndns.org   or
	      dual@dyndns.org, statdns@dyndns.org or custom@dyndns.org.

	      There	is     only	one	acceptable     service	   for
	      http://freedns.afraid.org, which is default@freedns.afraid.org.

	      This option can be used multiple times  -	 once  for  each  DDNS
	      server to	update - followed by --alias, and other	options	corre-
	      sponding to the --dyndns_system entry. Per --dyndns_system entry
	      options	are   username,	  password,   alias,   ip_server_name,
	      ip_server_host,  dyndns_server_name,   dyndns_server_url,	  dyn-
	      dns_server_host, and proxy_server.

TYPICAL	USAGE
   http://www.dyndns.org
       inadyn-mt -u username -p	password -a my.registered.name

       inadyn-mt --username test --password test --update_period 60000 --alias
       test.homeip.net --alias my.second.domain

       inadyn-mt  --background	-u  test -p test --update_period 60000 --alias
       inarcis.homeip.net --alias my.second.domain --log_file inadyn-mt.log

   http://freedns.afraid.org
       inadyn-mt  --dyndns_system  default@freedns.afraid.org	-a   my.regis-
       trated.name,hash_from_freedns

       inadyn-mt  --update_period 60000	--alias	test.homeip.net,hash_for_host1
       -a my.second.domain,hash2 --dyndns_system default@freedns.afraid.org

       This provider prefers to	get as parameter a single hashed  (base64  en-
       coded) value.

       As of inadyn-mt version 02.24.07-afraid_00_patch, aliases hashes	can be
       automatically obtained via sha1 hashed  'username|password'.   To  this
       end, use	options	username, and password.

       Otherwise,  the	freedns.afraid.org  DDNS web user interface provides a
       "Direct URL" link via which corresponding alias hash may	be copied, and
       pasted into inadyn-mt config as alias option hash paramter.

       Example:	   Resulting	address	   window   url	  looks	  like	 this:
       http://freedns.afraid.org/dynamic/update.php?YUGIUGSEIUFGOUI-
       HEOIFEOIHJFEIO=

       The  user  has to copy and paste	the hash value after the '?' until the
       end of line.

       The hash	will be	used as	additional param in --alias option. (see typi-
       cal usage above)

OUTPUT
       inadyn-mt prints	a message when the IP is updated.  When	the connection
       goes down it could be that inadyn-mt will print	some  error  messages.
       Those  are  harmless  and should	be followed by 'OK' messages after the
       connection is back up.

Signals
       Any of the SIG_HUP, SIG_INT, SIG_QUIT will cause	inadyn-mt to terminate
       gracefully.  SIG_USR1 will cause	inadyn-mt to update ip,	if changed.

       mt.conf(5).
