Salaries and Services Costs Microsoft and Linux

Network Infrastructure Specification and Costs
Network Infrastructure is calculated as the cost of equipping one computer, whether it be a
workstation or a server, with a connection point on a port or a switch, appropriate cabling
and a wall socket, as per current industry bestpractice.
Research has shown this turns out
to be approximately $100 per computer.
Therefore, network infrastructure is calculated as the number of computers multiplied by
$100.
Total Cost of Network Infrastructure 259 x $100 = $25,900.00
Staff Salary Specifications and Costs
Staff for both our Windows platform model and our Linux/Open Source environment were
sourced from online placement agency firms (such as Dice.com and Mojolin.com). We
performed a search using some of the core technologies required for both platforms, and
itemised three core staff members for our example organisation. We require a Senior
systems administrator and coordinator,
reporting to our example firm's executive
management. We also require a midlevel
generalist, and a junior helpdesk
support
staffer. Ancillary or specialist technical services will be provided by external consultants.

Disabling Shutdown Via Ctrl-Alt-Del

By default, /etc/inittab species that your system is set to shutdown and reboot the system in
response to a [Ctrl]-[Alt]-[Del] key combination used at the console. If you would like to completely disable this ability, you will need to comment out the following line in /etc/inittab by putting a hash mark (#) in front of it:ca::ctrlaltdel:/sbin/shutdown -t3 -r now Alternatively, you may just want to allow certain non-root users the right to shutdown the system from the console using [Ctrl]-[Alt]-[Del]. You can restrict this privilege to certain users, by taking the following steps: 1. Add a -a option to the /etc/inittab line shown above, so that it reads: ca::ctrlaltdel:/sbin/shutdown -a -t3 -r now The -a ag tells shutdown to look for the /etc/shutdown.allow le, which you will create in the next step. 2. Create a le named shutdown.allow in /etc. The shutdown.allow le should list the usernames of any users who are allowed to shutdown the system using [Ctrl]-[Alt]-[Del].

The format of the /etc/shutdown.allow le is a list of usernames, one per line, like the following: stephen jack sophie According to this example shutdown.allow le, stephen, jack, and sophie are allowed to shutdown the system from the console using [Ctrl]-[Alt]-[Del]. When that key combination is used, the shutdown -a in /etc/inittab checks to see if any of the users in /etc/shutdown.allow (or root) are logged in on a virtual console. If one of them is, the shutdown of the system will continue; if not, an error message will be written to the system console instead. For more information on shutdown.allow see the shutdown man page.
