## NAME

vlmcsd.ini - vlmcsd KMS emulator configuration file

## SYNOPSIS

vlmcsd.ini

## DESCRIPTION

vlmcsd.ini (or simply called the "ini file") is a configuration file for vlmcsd(8). By default vlmcsd does not use a configuration file. It is completely optional and for advanced users only. You must use the -i option on the vlmcsd command line to use an ini file. There is no default name or default location for the ini file.

Everything, that can be configured in the ini file, may also be specified on the command line. Any configuration option specified on the command line takes precedence over the respective configuration line in the ini file.

Benefits of a configuration file

While you can use the configuration file to simply modify the default behavior of vlmcsd, it can also be used to change the configuration of vlmcsd after you sent a HUP signal(7). Whenever you send SIGHUP, the configuration file will be re-read. Any changes you made to the ini file will be reflected after vlmcsd received the hangup signal.

Differences between command line and configuration file

If you specify an illegal option or option argument on the command line, vlmcsd displays help and exits. If you specify an incorrect keyword or argument in the ini file, vlmcsd displays a warning with some information, ignores the respective line and continues. This is intentional and prevents vlmcsd from aborting after a SIGHUP if the configuration was modified incorrectly.

## SYNTAX

vlmcsd.ini is a UTF-8 encoded text file with each line being in the format keyword = argument. The keyword is not case-sensitive. The argument is treated literally. It is neither required nor allowed to enclose the argument in any form of quote characters except when quote characters are part of the argument itself. Whitespace characters are ignored only

- at the beginning of a line
- between the keyword and ’=’
- between ’=’ and the argument

Lines, that start with ’#’ or ’;’ are treated as comments. Empty lines are ignored as well. If a keyword is repeated in another line, vlmcsd will use the argument of the last occurence of the keyword. An exception to this is the Listen keyword which can be specified multiple times and causes vlmcsd to listen on more than one IP address and/or port.

Some arguments are binary arguments that need to be either TRUE or FALSE. You can use "Yes", "On" or "1" as an alias for TRUE and "No", "Off" or "0" as an alias for FALSE. Binary arguments are case-insensitive.

## KEYWORDS

The following keywords are defined (not all keywords may be available depending on the operating system and the options used when vlmcsd(8) was compiled):

Listen

This defines on what combinations of IP addresses and ports vlmcsd should listen. Listen can be specified more than once. The argument has the form ipaddress[:port]. If you omit the port, the default port of 1688 is used. If the ipaddress contains colons and a port is used, you must enclose the ipaddress in brackets. The default is to listen to 0.0.0.0:1688 and [::]:1688 which means listen to all IPv4 and all IPv6 addresses. See the -L option in vlmcsd(8) for more info about the syntax. If you use -L or -P on the command line, all Listen keywords in the ini file will be ignored. The Listen keyword cannot be used if vlmcsd has been compiled to use Microsoft RPC (Windows and Cygwin only) or simple sockets.

Examples:

Listen = 192.168.1.123:1688
Listen = 0.0.0.0:1234
Listen = [fe80::1721:12ff:fe81:d36b%eth0]:1688

| Port |  | Can only be used if vlmcsd has been compiled to use simple sockets or on Windows and Cygwin if vlmcsd(8) has been compiled to use Microsoft RPC. Otherwise you must use Listen instead. Causes vlmcsd to listen on that port instead of 1688.

FreeBind

Can be TRUE or FALSE. If TRUE, you can use the Listen keyword with IP addresses that are currently not defined on your system. vlmcsd(8) will start listening on these IP addresses as soon as they become available. This keyword is only available under Linux and FreeBSD because no other OS currently supports that feature. FreeBSD supports this only for IPv4 and requires the PRIV_NETINET_BINDANY privilege which is normally assigned to proccesses of the root user.

PublicIPProtectionLevel

Set the level of protection against KMS activations from public IP addresses.

0 = No protection (default)
1 = Listen on private IP addresses only (plus those specified by one or more Listen statements)
2 = Disconnect clients with public IP addresses without activating
3 = Combines 1 and 2

For details on public IP protection levels see vlmcsd(8) command line option -o.

UseNDR64

Can be TRUE or FALSE. Specifies whether you want to use the NDR64 transfer syntax. See options -n0 and -n1 in vlmcsd(8). The default is TRUE.

UseBTFN

Can be TRUE or FALSE. Specifies whether you want to use bind time feature negotiation in RPC. See options -b0 and -b1 in vlmcsd(8). The default is TRUE.

RandomizationLevel

The argument must 0, 1 or 2. This specifies the ePID randomization level. See options -r0, -r1 and -r2 in vlmcsd(8). The default randomization level is 1. A RandomizationLevel of 2 is not recommended and should be treated as a debugging level.

| LCID |  | Use a specific culture id (LCID) even if the ePID is randomized. The argument must be a number between 1 and 32767. While any number in that range is valid, you should use an offcial LCID. A list of assigned LCIDs can be found at http://msdn.microsoft.com/en-us/goglobal/bb964664.aspx. On the command line you control this setting with option -C.

MaxWorkers

The argument specifies the maximum number of worker processes or threads that will be used to serve activation requests concurrently. This is the same as specifying -m on the command line. Minimum is 1. The maximum is platform specific and is at least 32767 but is likely to be greater on most systems. The default is no limit.

ConnectionTimeout

Used to control when the vlmcsd disconnects idle TPC connections. The default is 30 seconds. This is the same setting as -t on the command line.

DisconnectClientsImmediately

Set this to TRUE to disconnect a client after it got an activation response regardless whether a timeout has occured or not. The default is FALSE. Setting this to TRUE is non-standard behavior. Use only if you are experiencing DoS or DDoS attacks. On the command line you control this behavior with options -d and -k.

PidFile

Write a pid file. The argument is the full pathname of a pid file. The pid file contains is single line containing the process id of the vlmcsd process. It can be used to stop (SIGTERM) or restart (SIGHUP) vlmcsd. This directive can be overriden using -p on the command line.

LogFile

Write a log file. The argument is the full pathname of a log file. On a unixoid OS and with Cygwin you can use the special filename ’syslog’ to log to the syslog facility. This is the same as specifying -l on the command line.

LogDateAndTime

Can be TRUE or FALSE. The default is TRUE. If set to FALSE, logging output does not include date and time. This is useful if you log to stdout(3) which is redirected to another logging mechanism that already includes date and time in its output, for instance systemd-journald(8). If you log to syslog(3), LogDateAndTime is ignored and date and time will never be included in the output sent to syslog(3). Using the command line you control this setting with options -T0 and -T1.

LogVerbose

Set this to either TRUE or FALSE. The default is FALSE. If set to TRUE, more details of each activation will be logged. You use -v and -q in the command line to control this setting. LogVerbose has an effect only if you specify a log file or redirect logging to stdout(3).

WhitelistingLevel

Can be 0, 1, 2 or 3. The default is 0. Sets the whitelisting level to determine which products vlmcsd activates or refuses.

0: activate all products with an unknown, retail or beta/preview KMS ID.
1: activate products with a retail or beta/preview KMS ID but refuse to activate products with an unknown KMS ID.
2: activate products with an unknown KMS ID but refuse products with a retail or beta/preview KMS ID.
3: activate only products with a known volume license RTM KMS ID and refuse all others.

| The SKU ID is not checked. Like a genuine KMS server vlmcsd activates a product that has a random or unknown SKU ID. If you select 1 or 3, vlmcsd also checks the Application ID for correctness. If Microsoft introduces a new KMS ID for a new product, you cannot activate it if you used 1 or 3 until a new version of vlmcsd is available.

CheckClientTime

Can be TRUE or FALSE. The default is FALSE. If you set this to TRUE vlmcsd(8) checks if the client time differs no more than four hours from the system time. This is useful to prevent emulator detection. A client that tries to detect an emulator could simply send two subsequent request with two time stamps that differ more than four hours from each other. If both requests succeed, the server is an emulator. If you set this to TRUE on a system with no reliable time source, activations will fail. It is ok to set the correct system time after you started vlmcsd(8).

MaintainClients

Can be TRUE or FALSE (the default). Disables (FALSE) or enables (TRUE) maintaining a list of client machine IDs (CMIDs). TRUE is useful to prevent emulator detection. By maintaing a CMID list, vlmcsd(8) reports current active clients exactly like a genuine KMS emulator. This includes bug compatibility to the extent that you can permanently kill a genuine KMS emulator by sending an "overcharge request" with a required client count of 376 or more and then request activation for 671 clients. vlmcsd(8) can be reset from this condition by restarting it. If FALSE is used, vlmcsd(8) reports current active clients as good as possible. If no client sends an "overcharge request", it is not possible to detect vlmcsd(8) as an emulator with MaintainClients = FALSE. Maintaining clients requires the allocation of a buffer that is about 50 kB in size. On hardware with few memory resources use it only if you really need it.

If you start vlmcsd(8) from an internet superserver, this setting cannot be used. Since vlmcsd(8) exits after each activation, it cannot maintain any state in memory.

StartEmpty

This setting is ignored if you do not also specify MaintainClients = TRUE. If you specify FALSE (the default), vlmcsd(8) starts up as a fully "charged" KMS server. Clients activate immediately. StartEmpty = TRUE lets you start up vlmcsd(8) with an empty CMID list. Activation will start when the required minimum clients (25 for Windows Client OSses, 5 for Windows Server OSses and Office) have registered with the KMS server. As long as the minimum client count has not been reached, clients end up in HRESULT 0xC004F038 "The count reported by your Key Management Service (KMS) is insufficient. Please contact your system administrator". You may use vlmcs(1) or another KMS client emulator to "charge" vlmcsd(8). Setting this parameter to TRUE does not improve emulator detection prevention. It’s primary purpose is to help developers of KMS clients to test "charging" a KMS server.

ActivationInterval

This is the same as specifying -A on the command line. See vlmcsd(8) for details. The default is 2 hours. Example: ActivationInterval = 1h

RenewalInterval

This is the same as specifying -R on the command line. See vlmcsd(8) for details. The default is 7 days. Example: RenewalInterval = 3d. Please note that the KMS client decides itself when to renew activation. Even though vlmcsd sends the renewal interval you specify, it is no more than some kind of recommendation to the client. Older KMS clients did follow the recommendation from a KMS server or emulator. Newer clients do not.

User

Run vlmcsd as another, preferrably less privileged, user. The argument can be a user name or a numeric user id. You must have the required privileges (capabilities on Linux) to change the security context of a process without providing any credentials (a password in most cases). On most unixoid OSses ’root’ is the only user who has these privileges in the default configuration. This setting is not available in the native Windows version of vlmcsd. See -u in vlmcsd(8). This setting cannot be changed on the fly by sending SIGHUP to vlmcsd.

Group

Run vlmcsd as another, preferrably less privileged, group. The argument can be a group name or a numeric group id. You must have the required privileges (capabilities on Linux) to change the security context of a process without providing any credentials (a password in most cases). On most unixoid OSses ’root’ is the only user who has these privileges in the default configuration. This setting is not available in the native Windows version of vlmcsd. See -g in vlmcsd(8). This setting cannot be changed on the fly by sending SIGHUP to vlmcsd.

Windows

The argument has the form ePID [ / HwId ]. Always use ePID and HwId for Windows activations. If specified, RandomizationLevel for Windows activitations will be ignored.

Office2010

The argument has the form ePID [ / HwId ]. Always use ePID and HwId for Office 2010 activations. If specified, RandomizationLevel for Office 2010 activitations will be ignored.

Office2013

The argument has the form ePID [ / HwId ]. Always use ePID and HwId for Office 2013 activations. If specified, RandomizationLevel for Office 2013 activitations will be ignored.

Office2016

The argument has the form ePID [ / HwId ]. Always use ePID and HwId for Office 2016 activations. If specified, RandomizationLevel for Office 2016 activitations will be ignored.

## VALID EPIDS

The ePID is currently a comment only. You can specify any string up to 63 bytes. In Windows 7 Microsoft has blacklisted few ( < 10 ) ePIDs that were used in KMSv5 versions of the "Ratiborus Virtual Machine". Microsoft has given up on blacklisting when KMS emulators appeared in the wild.

Even if you can use "Activated by cool hacker guys" as an ePID, you may wish to use ePIDs that cannot be detected as non-MS ePIDs. If you don’t know how these "valid" ePIDs look like exactly, do not use GUIDS in vlmcsd.ini. vlmcsd provides internal mechanisms to generate valid ePIDs.

If you use non-ASCII characters in your ePID (you shouldn’t do anyway), these must be in UTF-8 format. This is especially important when you run vlmcsd on Windows or cygwin because UTF-8 is not the default encoding for most editors.

If you are specifying an optional HWID it follows the same syntax as in the -H option in vlmcsd(8) ecxept that you must not enclose a HWID in quotes even if it contains spaces.
