For maximum flexibility in your licensing options, you can define the HostID values for your protected application within the license rather than inside the protected application. This enables you to license your application differently for different users, without requiring your application to be recompiled.

...

The following HostIDs are supported in the license:

For help on deciding which HostID or combination of HostIDs fits your needs, see Determining which HostID to use.   For complete information about the operating system versions that are supported by LM-X, see Supported platforms.   

 LMX_HOSTID_ETHERNET

For license generation, LM-X can handle different Ethernet HostID formats in the license template based on the operating system representation of the address when using ipconfig (Windows) or ifconfig (Unix); for example, AABBCCDDEEFF, AA:BB:CC:DD:EE:FF or AA-BB-CC-DD-EE-FF.

When using LMX_HOSTID_DONGLE_HASPHL with local standalone licenses, the client application should ensure that the dongle is not removed during client runtime.

One way to You can check the dongle is by calling LMX_Heartbeat on a separate thread continuously, or by ensuring that LMX_HOSTID_DONGLE_HASPHL HostID is in use and , if so, comparing the HostID value against the last known good value, as demonstrated in the following example. 

int i;
LMX_FEATURE_INFO FI;
LMX_HOSTID LmxHostid[LMX_MAX_HOSTIDS];
int nHostids;
LMX_GetFeatureInfo(LmxHandle, "my_app", &FI);
/* Go through each hostid used for this particular feature */
for (i = 0; i < FI.nClientLicenseHostids; i++)
{
  /* See if the hostid is a dongle hostid */
  if (FI.ClientLicenseHostid[i].nHostidType == LMX_HOSTID_DONGLE_HASPHL)
  {
    /* See if hostid function reports the same value as we used when checking out the license */
    if (LMX_Hostid(LmxHandle, LMX_HOSTID_DONGLE_HASPHL, LmxHostid, &nHostids)!= LMX_SUCCESS) 
      return BAD_DONGLE;
    if (nHostidnHostids != 1)
      return BAD_DONGLE;
    /* Compare if the hostid at checkout time matches the hostid at present time */
    if (strcmp(FI.ClientLicenseHostid[0].szValue, LmxHostID[0].szValue) != 0) 
      return BAD_DONGLE;
  }
}
