icmp again..

icmp again..

[Martin Svenningsson]

Hello.

I wonder if someone can tell me how to use ICMP with cygnus wunderful gcc.exe.

The icmp.h and ip_icmp.h is empty, and I read in this lists archive that
winsock don't handle ICMP in the same way as unix, but there was .h's
fixing it and calling icmp.dll(?). The guy who wrote that mail said that I
(well, us;P) should search for a file named ICMP_API.ZIP, but I can't find
anyting named that nor something like it.

I found a ms_icmp.h somewhere, but gcc don't like it.

Will be glad if someone can help me :)

btw, im trying to port the icmpinfo-1.11, which is an excellent
icmp-logger. If someone already ported it (or simular) please let me know.

Thanx.

Will we see the use of winsock2 in the future (b19) releases of great 
cygwin32 tools... Winsock2 is out for win95 an winNT allready has it 
an it does support raw sockets or most of them.. I know there's a few 
problems with UDP an IPPROTO_RAW. Will we see it in use?

You can use winsock functions in the normal (socket) way to write
icmp packets out.  Unfortunately the winsock functions are
somewhat of a hack for reading back packets.  It appears that
you only get packets back in a recv that are a response to
a ping icmp packet you sent out.  In other words, it's almost
completely unusable for reading icmps.

Winsock is incapable of reading arbitrary icmps so you would
need some other way to read icmps to make an icmp logger.

Check out Chris Becke's page on icmp programing at
http://www.dbn.lia.net/chris/icmp.html .  He has hacked the add-on DLL
Windows uses to handle ICMP packets.  The page has a .ZIP file containing
source and a decent discussion of what's involved.
