| 1. Execute make first. This will result in a netlinkKernel.ko output among many others. | |
| 2. Execute $ gcc netlinkUser.c -o netlinkUser | |
| 3. Insert kernel module by :$ sudo insmod netlinkKernel.ko | |
| 4. Run ./netlinkUser to see message and run dmesg to see debug messages | |
| 5. Remove module by : $ sudo rmmod netlinkKernel | |
| 6. Finally make clean to remove output files. |
