Our lab contains 10 different hosts named cslab1, cslab2,...,cslab10. Each runs Linux. The hostnamectl command lists information about the machine on which it is run including the version of Linux running on it. For example, the hostnamectl command shows that eniac is running Linux 2.10.0-130-generic. The first number, 2, is the version number. The second, 10, is the major release number. The third, 0, the minor release number, and the last, the patch number.

Q1How many different versions of Linux are running in total on all of the cslab hosts?

Q2A release is a version together with the major release number, such as 2.10. How many different releases are running in total on these hosts?

Q3How many different Linux kernels are running on the different cslab hosts in our lab? In the space below, write this number as an integer. Consider two kernels different if they do not have the exact same (version, major,minor, patch) number. If a host is unreachable, write the answer based on the remaining hosts.

Q4What is the latest version of Linux running in the lab?
