Please correct me
Based on the best available info
- What is the kernel version of Linux on matrix?
- What is the IP address and MAC address of the Linux machine on matrix?
- What is the network mask on matrix?
- What are the network addresses of the Linux machine? (there should be three networks)
- What is the IP address of the gateway for the Linux machine on matrix?
- What is the command to display all the currently loaded kernel modules?
- Where is the file for the kernel module called "e100"?
- What is the MAC address for the network device that has the IP address 192.168.1.254?
- How do you display all the physically network addresses known by a Linux machine?</a>
