Track availability of computers

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:
I must write a program that records the availability of computers. For the argument i have to give him a file containing a list of computers, the program should check every five minutes if they are available. If a computer is not reachable, then the program should write into the file the name of computer and the time when it was't available.

Example usage:

$ Check list_of_computers.txt

The print in the file:

io.something.si not reachable at 15:31
io.something.si not reachable at 15:36
io.something.si not available at the 15:41
verbena.something.si not reachable at 15:41

2. Relevant commands, code, scripts, algorithms:
?

3. The attempts at a solution (include all code and scripts):
The command "ping" is given as a hint

Any ideas?

How Many Computers Do You Have At Home?

Here is an easy one. Count the number of desktops and servers you have running at home, including your home office if you have one. Don't count those that are in storage or you rarely use, count the ones that are powered on most, if not all, of the day (and night).

lmfsetup(8) System Manager's Manual lmfsetup(8)

Name
lmfsetup - License Management Facility PAK registration script

Syntax
/etc/lmfsetup [ template ]

Description
The script allows you to register data supplied by a Product Authorization Key (PAK). The script prompts you for the data associated with
each of the fields on a PAK. When all the data has been entered, the License Management Facility (LMF) ensures there are entries against
all the mandatory fields, and that the Checksum validates all the license data. If the data has been entered correctly, the PAK is regis-
tered in the License Database. If the data has been entered incorrectly, the appropriate error message is displayed and you are given the
opportunity to re-enter the data.

The template option allows you to register license data from templates in A template containing a partially complete PAK is created by some
products as part of their installation process. The script only prompts you for data on the fields that are empty in the template. If the
script cannot find the specified template in it searches the current directory.

The script is provided as an alternative to the command. This displays a template, which includes the fields on the PAK, and invokes an
editor so that you can add the license data to the appropriate field. The command also allows errors to be corrected without having to re-
enter all the data.
