Does Indy ping require UAC elevation?

问题

Does the Indy ICMP component require Administrator privileges to ping?

If I run with UAC turned on but without elevated privileges I get an "Access Denied" error message.
Looking at this question it sounds like Indy ICMP uses RAW sockets and thus needs elevated privileges?

I'm developing using Delphi 2007 & Indy 10.x and testing under Windows 7 Pro.

回答1:

My colleague found this Article states that the Indy ICMP component uses RAW Windows sockets, which under Vista or later requires elevated privileges to run under UAC.

I adapted the program to request UAC elevation and it's now pinging okay.

The alternative would be to call the ICMPSendEcho() and it's related functions directly.
