- 1. What is the kernel version on matrix?
lsdaly@matrix:~> uname -r kernel release is 2.6.18.8-0.5-default Kernel version of linux on matrix is #1 SMP Tue Feb 12 09:16:51 EST 2008
- 2. What is the IP address and MAC address of the Linux machine on matrix?
- from /sbin/ifconfig:
HWaddr: 00:0E:0C:74:9C:F9 IP: 192.168.1.69
- 3. What is the network mask on matrix?
Mask:255.255.255.0
- 4. What are the network addresses of the Linux machine? (there should be three networks)
