License Problem

Host ID is required to register a license. According to this article, Host ID is the MAC address of eth0. However, what my PC has is enp0s25 rather than eth0. So, I used the MAC address of enp0s25 to register a license and placed it in /opt/intel/licenses/. 

When I executed icc, it gives the following information:

$ icc

Error: A license for (Comp-CL) could not be found.
License file(s) used were (in this order):
    1.  Trusted Storage
**  2.  /opt/intel/licenses/NCOM____3VGW-GX7RW6P9_1.lic
**  3.  /opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/../../Licenses
**  4.  /home/purboo/Licenses
**  5.  /Users/Shared/Library/Application Support/Intel/Licenses
**  6.  /opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/*.lic

icc: error #10052: could not checkout FLEXlm license

How can I resolve this issue? Thank you!
