要搭建一个与正式环境一样的测试环境，有些硬件设备没办法复制过来，就只有用软件版了。幸好，Citrix官方有出一个Netscaler VPX，在Citrix官网注册一个账户，申请一个免费license就可以使用一年了，以下就是申请license时需要的信息（MAC地址）.
官网参考链接：
Each of the license keys will generate one Citrix NetScaler license. You will repeat the process of allocating a license with a unique license key for each device. Each license file will be unique for a specific NetScaler device and must be installed only on that device.
The “lmutil” command is only available on systems running Release 8.0 and later. For Evaluation units that involve an upgrade (such as an older unit being used to test platinum features,) customers need to upgrade the box to 8.0 before executing the following Imutil instructions.
To obtain the Host ID:
1. Log on to the NetScaler CLI using SSH or the console.
2. Drop to the BSD shell by typing the shell command.
3. From the shell, use the following command:
lmutil lmhostid –ether
Example:
root@ns1# lmutil lmhostid –ether

The FLEXlm host ID of this machine is “00d068107316″
NOTE: lmutil command needs to be run on each system in an HA pair
