Raw Sockets and SP2...

Devil Panther · 05-24-2005, 10:19 AM

Well, as we all know microsoft killed raw sockets on windows machines with their sp2 for XP, and their "illegal" patch for people who didn't want sp2 on their machines!

But the question remains, if i don't have raw sockets... can i still write applications that use icmp? like PING that uses icmp request.
Because as far as i know, raw sockets is the only way to generate an icmp packet, but there aren't any raw sockets on "patched" windows machines, then how could it be that the PING program still works?

thank you.

The only two restrictions to raw sockets in SP2 are:

TCP data cannot be sent over raw sockets.
UDP datagrams with invalid source addresses cannot be sent over raw sockets. The IP source address for any outgoing UDP datagram must exist on a network interface or the datagram is dropped.

i see.... so those are the only restrictions?

You don't have to use raw sockets. There is also the ICMP.dll, although MS have been threatening to remove it for a few years now.

Check the winsock FAQ for details on how to use it. (although raw is a better method)

Is the icmp.dll supported by windows 2003?

eth0 · 05-26-2005, 03:53 PM

yes, they haven't removed it (and I doubt they will be doing any time soon)

The document says I need to use icmpapi.h but neither my VC++ Studio nor the Borland C++ has it... Why?

But why do i need an update if it's an old header? It's practically obsolete.

Also, how can I update my Borland C++ 5.5 compiler?

I'm sorry to bring the topic back up, but I really need an answer on this question
