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?

For boolean options you can override the config file by using something like -f-,--no-f, -f=no or several other variations. -t, --tempdir Temporary directory in which to write extracted debconf template files and config scripts.
