Ping sources (WinSock2)...
I need Delphi 4 sources (no components without sources, please) for a little ping function using WinSock2 (no ICMP.DLL, please).
Thank you... :-)
Regards, Madshi.

BlackMan,
thanx for your answer. Unfortunately Andreas' components are based on WinSock(1) and the "ICMP.DLL". Look at this extract from one of his units:
{ Microsoft doesn't support the standard way ICMP is implemented using
sockets, that means by the SOCK_RAW socket type - they only work as
user administrator! And there's no way to set the TTL for the packets, so
there's no way to build a TraceRoute using winsock. So this unit uses their
ICMP.DLL, although MS discourages it's use - once they have a better solution
this properitary implementation will vanish. So be careful where you
use this unit! }
With WinSock2 Microsoft DOES support SOCK_RAW. So I need an implementation of ping for WinSock2.
Sorry, Madshi.

I think that is a "general" comment-cut from the WinSock site, the history.txt says:
1997-07-02 0.2 added support for winsock ICMP calls (TPing only yet)
And if you look at the TPing component in ICMP.PAS, it look like it has a socket-mode..

Andreas Hörstemeier has a packagde with both a ICMP and a Socket version of Ping.
