NAME
       vlmcs - a client for testing and/or charging KMS servers


SYNOPSIS
       vlmcs [ options ] [ target ] [ options ]

       target can be one of the following:

              hostname|ipaddress[:tcp-port]  or to query a specific KMS server
              (example: vlmcs kms.example.com:1688).
              .domain to automatically detect KMS servers via DNS  for  domain
              (example:  vlmcs  .example.com).  Please  note  the  dot  before
              domain.
              - (a single dash) to detect KMS servers in your own domain.

       If you use ipaddress:port as the target, the ipaddress must be enclosed
       in  brackets  if it contains colons, e.g. [2001:db8:dead:beef::1]:1688.
       If you use a link-local IPv6 address on Unix systems, you must append a
       percent  sign and the interface identifier of the source interface, for
       example fe80::dead:beef%eth0.

       If you omit the target, 127.0.0.1:1688 will be used except if  you  use
       -i6. In this case the default target is [::1]:1688.


DESCRIPTION
       vlmcs  is a program that can be used to test a KMS server that provides
       activation for several Microsoft products. The KMS server may  also  be
       an emulator. It supports KMS protocol versions 4, 5 and 6.

       vlmcs  generates  one  or  more activation requests for a Microsoft KMS
       product and sends it to a KMS server. It then analyzes and displays the
       responses of the KMS server.

       vlcms  checks  both the DCE-RPC protocol and the activation message for
       correctness and reports any errors that it finds.

       vlmcs can also be used to "charge" a KMS server. A Microsoft KMS server
       sends  correct activation messages only if it detects a certain minimum
       of clients (25 for Windows client OSses, 5 otherwise) on  the  network.
       This is Microsoft's futile attempt to prevent running a KMS server in a
       home environment.


OPTIONS
       -h or -?
              Show help.


       -x     Show valid applications that can be used with -l.


       -e     Show some examples how to use vlmcs correctly.


       -v     Be verbose. Instead of just displaying the returned ePID and the
              HwId  (protocol  v6  only) vlmcsd shows all details of the query
              and the response.


       -l application
              Request activation for a specific application.   Valid  applica‐
              tions  can be displayed by using -x.  The default application is
              Windows Vista Business.  The list of available  applications  is
              not complete. You may supply GUIDs with -a, -k and -s to specify
              applications that are not listed with -x. The -l option is  used
              as a shortcut for the most common applications.


       -4, -5 and -6
              Force  version  4, 5 or 6 of the KMS protocol. The default is to
              select a suitable version according to the application selected.
              Plese note that some products (e.g. Office 2013) may use differ‐
              ent protocols with different versions of Windows.


       -m     Let the client pretend to be a virtual machine.  Early  versions
              of  Microsoft's  KMS server did not increase the client count if
              the request came from a virtual machine. Newer  versions  ignore
              this flag.


       -d     Use NetBIOS names instead of DNS names. By default vlmcsd gener‐
              ates some random DNS names for each request. If you prefer  Net‐
              BIOS  names, you may use -d.  A real Microsoft activation client
              uses DNS names or NetBIOS depending on the client name  configu‐
              ration. KMS servers treat the workstation name as a comment that
              affects logging only. Clients will be identified by a GUID  that
              can  be specified using -c. -d has no effect if you also specify
              -w.


       -a application-guid
              Send requests with a specific application-guid.  There are  cur‐
              rently only three known valid application-guids:


              55c92734-d682-4d71-983e-d6ec3f16059f (Windows)
              59a52881-a989-479d-af46-f275c6370663 (Office 2010)
              0ff1ce15-a989-479d-af46-f275c6370663 (Office 2013)


              A  Microsoft  KMS server uses these GUIDs to have seperate coun‐
              ters for the already activated clients. A client that  does  not
              contact  the  KMS server within 30 days will be deleted from the
              database. Emulated KMS servers are always fully charged.


       -k kms-guid
              Send requests with a specific kms-guid.  A Microsoft KMS  server
              uses  these  GUIDs  as  a  product id to decide whether to grant
              activation or not. A list of current kms-guids can be  found  in
              kms.c  (table  KmsIdList). Emulated KMS servers grant activation
              unconditionally and do not check the kms-guid.


       -s activation-guid
              The activation-guid defines the actual  product,  e.g.  "Windows
              8.1  Professional WMC KMSCLIENT edition". A activation-guid maps
              1:1 to a product key.  However, neither a Microsoft  KMS  server
              nor emulated servers check this id.  The activation-guid is use‐
              ful in logging to get a specific product description like  "Win‐
              dows  8.1  Professional WMC". A list of current activation-guids
              can be found in kms.c (table ExtendedProductList).


       -n requests
              Send requests requests to the server. The default is to send  at
              least one request and enough subsequent requests that the server
              is  fully  charged  afterwards  for  the  application-guid   you
              selected (explicitly with -a or implicitly by using -l).


       -T     Causes  to use a new TCP connection for each request if multiple
              requests are sent with vlmcsd. This is useful when you  want  to
              test  an  emulated  KMS  server  whether  it suffers from memory
              leaks. To test for memory leaks use -n with a  large  number  of
              requests  (>  100000) and then test twice (with and without -T).
              This option may become neccessary for future versions of  Micro‐
              soft's  KMS  server  because  multiple  requests  with different
              clients-guids for the same kms-id-guid are impossible in a  real
              KMS szenario over the same TCP connection.


       -c client-machine-guid
              Normally  vlmcs  generates a random client-machine-guid for each
              request. By using this option you can specify  a  fixed  client-
              machine-guid  This  causes  a Microsoft KMS not to increment its
              client count because it receives multiple requests for the  same
              client.  Thus  do  not  use  -c if you want to charge a real KMS
              server.


       -o previous-client-machine-guid
              If the client-machine-guid changes for some reason, the real KMS
              client  stores  a  previous-client-machine-guid which is sent to
              the   KMS   server.   This   happens    rarely    and    usually
              00000000-0000-0000-0000-000000000000  is used. You can use -o to
              specify a different previous-client-machine-guid.


       -G filename
              Grabs ePIDs and HWIDs from a KMS server and writes the  informa‐
              tion  to  filename in format suitable to be used as a configura‐
              tion file (aka ini file) for vlmcsd(8).  This is especially use‐
              ful  if  you have access to a genuine KMS server and want to use
              the same data with vlmcsd(8).

              If filename does not exist, it will be created.  If you  specify
              an  existing filename, it will be updated to use the information
              received from the remote KMS server and a backup filename~  will
              be created.

              -G cannot be used with -l, -4, -5, -6, -a, -s, -k, -r and -n


       -w workstation-name
              Send  requests  with a specific workstation-name.  This disables
              the random generator for the workstation name.  Since  it  is  a
              comment only, this option does not have much effect.


       -r required-client-count
              Also  known  as  the "N count policy". Tells the KMS server that
              successful activation  requires  required-client-count  clients.
              The  default is the required-client-count that the product would
              need if the request was  a  real  activation.  A  Microsoft  KMS
              server counts clients up to the double amount what was specified
              with -r. This option can be used to "overcharge" a Microsoft KMS
              server.


       -t status
              Reports a specific license status to the KMS server. status is a
              number that can be from 0 to 6. 0=unlicensed, 1=licensed,  2=OOB
              grace,   3=OOT   grace,  4=Non-genuinue  grace,  5=notification,
              6=extended grace. Refer to TechNet ⟨http://
              technet.microsoft.com/en-us/library/ff686879.aspx#_Toc257201371⟩
              for more information.  A  Microsoft  KMS  server  collects  this
              information for statistics only.


       -g binding-expiration
              This  tells  the  KMS  server how long a client will stay in its
              current license status. This can be the remaining OOB time  (the
              grace  peroid  that is granted between installation of a product
              and when activation is actuall required) or the  remaining  time
              when  KMS  activation  must  be  renewed.  binding-expiration is
              specified in minutes. A Microsoft KMS server apparantly does not
              use this information.


       -i protocol-version
              Force  the  use  of  Internet protocol protocol-version. Allowed
              values are 4 (IPv4) and 6 (IPv6). This option is useful only  if
              you  specfiy  a  hostname  and  not an ip-address on the command
              line.


       -p     Do not set the RPC_PF_MULTIPLEX flag in the  RPC  bind  request.
              This can be used to test if the KMS server uses the same setting
              of this flag in the RPC bind respone. Some KMS  emulators  don't
              set this correctly.


       -N0 and -N1
              Disables (-N0) or enables (-N1) the NDR64 transfer syntax in the
              RPC protocol. Disable NDR64 only in case of problems.  If  NDR64
              is not used, vlmcs cannot detect many RPC protocol errors in KMS
              emulators. If you want to test whether a KMS emulator fully sup‐
              ports  NDR64,  you  must  use the -n option to send at least two
              requests. This is because Microsoft's client  always  sends  the
              first  request  using NDR32 syntax and subsequent requests using
              NDR64 syntax.


       -B0 and -B1
              Disables (-B0) or enables (-B1) bind  time  feature  negotiation
              (BTFN)  in  the RPC protocol. Disable BTFN only in case of prob‐
              lems. If BTFN is not used, vlmcs cannot detect many RPC protocol
              errors in KMS emulators.


       Options  that do not require an argument can be specified together with
       a single dash, e.g. vlmcs -6mvT. If you specify  an  option  more  than
       once, the last occurence will be in effect.

BUGS
       Some  platforms  (e.g.  Solaris) may have a man(7) system that does not
       handle URLs. URLs may be omitted in the documentation  on  those  plat‐
       forms. Cygwin, Linux, FreeBSD and Mac OS X are known to work correctly.
