All computers connected to the Department network must respond to ping requests. Managed computers should have ping enabled by default, but personally-owned laptops often do not.

 

Windows

Open Control Panel, choose "System and Security", followed by "Windows Firewall Status", and then select "Advanced Settings". From the list at the list, click on "Inbound Rules". Sort the list that appears in the right hand panel by Name, and then look for settings entitled "File and Printer Sharing (Echo Request - ICMPv4-in)" and "File and Printer Sharing (Echo Request - ICMPv6-in)". Please enable all rules with either of those names by right-clicking and select "Enable rule".

Alternatively, you can open a command prompt as administrator and run the command

netsh advfirewall firewall add rule name="Enable ping" protocol=icmpv4:any,any dir=in action=allow

If you are trying to register a personally-owned laptop for use on the Department network and are still told that ping is not enabled after following these steps, it may be because you have third-party firewall and/or antivirus software installed that is blocking ping. Please contact us if this is the case and you are unable to enable ping.

Linux

Unfortunately, due to the wide range of different Linux distributions, it is not possible to offer general instructions that apply to all versions of Linux. However, ping is typically enabled by default on most Linux computers.

Mac OSX

OSX usually has ping enabled by default. The most common reason why OSX may not respond to ping requests is because "Stealth mode" has been enabled in the Firewall settings.
