The ISO standard C language does not define "ping", "suid state", "raw
sockets" or "root". In fact it does not even define "other computers".
Please ask in comp.unix.progr ammer.

No, not necessarily, it's just that you asked the question in the
wrong newgroup. Most people usually don't admit to knowing any-
thing here about C++, networking or what "suid state" or root
accounts are since the topic of this group is the C programming
language which does not have any build-in support for networking
or must be used on an OS were "suid state" or root accounts are
available. And for C++ there's another group. Sorry.

You probably should try comp.unix.progr ammer if the "suid state"
and root account bits aren't misleading me (but I guess I don't
really have to tell you about that group since you have already
posted there).

See http://www.planet-lab.org/raw_sockets/api.html, if you can live with
the limitations. There not true raw sockets, but better as nothing.
