With LM-X v3.3, hostids are no longer obfuscated, thereby making it easier to determine to what hardware item the license is locked and how the licensing is performed.

For example, versions of LM-X previous to v3.3 used a 16-digit Ethernet hostid (the obfuscated MAC address of the Ethernet card), as shown below:

ETHERNET: Intel(R) PRO/Wireless 3945ABG Network Connection
Hostid: 0C5E87A02B51C4F9

With LM-X v3.3, the Ethernet hostid information is now as follows:

ETHERNET: Intel(R) PRO/Wireless 3945ABG Network Connection
Hostid: 0018DEBC98A8

Compatibility notes

1. LM-X v3.3 can read existing licenses that use obfuscated hostids. However, by default the new license generator will generate licenses that are not compatible with existing clients. To avoid conflicts with existing deployed clients and licenses, you should use the new license generator only for new application deployments. If you want to preserve old host information, we recommend that you use your existing license generator to avoid mismatches.
   
   If you want to use the new license generator to generate a license file for a v3.3 license server but for pre-v3.3 license clients, you can use xmllicgen -oldhostid. For example, the following instructs xmllicgen to generate a license file with a pre-v3.3 (obfuscated ) hostid:
   
   xmllicgen -oldhostid -config ..\..\config\vendor.lmx -output token.lic token.xml
   
   
2. To get the previous hostid value, you can use lmxendutil -oldhostid, as in the following example:
   
   lmxendutil -oldhostid
   LM-X End-user Utility v3.3

   ETHERNET: Bluetooth Device (Personal Area Network)
   Hostid: D82F66029C4F266D
   
   
3. The LMX_HOSTID structure variables sValue and nLength have been deprecated. If you use the LMX_HOSTID structure, be sure to use the szValue variable instead.
