comment What happens when wifi channels overlap?
It is not entirely accurate to say there is no intelligently. Some high-end wifi gear can be setup to automatically adjust its power.

comment Terminal Server - Group Policy prevent command line
While I agree this is the problem and changing the policy may fix the issue, given the current OU/GPO structure making this change is not an option. Are their any alternatives? One thing that looks tempting is in the Session Host Configuration. There is an option User Login Mode where you can set the host to prevent new connections. Do you know how to modify the User Login Mode from a script/command line? I would like to be able toggle between Allow all and Prevent reconnections.

comment Does disabling root login enhance security?
Root via ssh does NOT automatically mean that the system is susceptible to brute force. Consider a system with the PermitRootLogin without-password option set.

comment Why shouldn't root be allowed to login via ssh?
Disabling root logins is required to protect against brute force. Disabling password-based authentication would also protect you against the people scanning and still allow you to authenticate as root with little risk. Running an IPS that kill connections after a few failed attempts will also be more helpful then just blocking root access.

comment users connecting to remote desktop to use software
Are you more curious about the potential license issue, or are you concerned about running applications from a Terminal server? We are not lawyers, I don't think we can offer you useful advice on if you are breaking a license agreement, and what the risk is.

comment Validating SSL clients using a list of authorised certificates instead of a Certificate Authority
@djangofan, Yes, to authenticate with a client certificate the end-user must get the certificate from somewhere and install it into the certificate store used by their browser.

comment Autologin on Ubuntu Server
Are you talking about logging in from the console or a remote system? If you are connecting from a remote system just setup SSH key-based authentication.

comment Why ethernet cables must be ended with specific arrangement
This is more then just about twists though. For example pins 1&2 should use the same pair, and 3&6 should use the same pair. This way the TX+ and TX- are on the same pair, and RX+, and RX- use the same pair. The point of having a TX+/- and RX+/- on a pair is so that any interference can be factored out since it should typically affect both the + and - wire the same way.

comment Why ethernet cables must be ended with specific arrangement
Just to bring up a point, but not all Ethernet is over UTP (unshielded twisted pair). (For example 10base2, and Fiber are Ethernet).
