Hi Jason,
Thanks very much for your response!
I check the ping & traceroute code, For ping:
if (options & F_TTL) {
if (IN_MULTICAST(ntohl(dst4.sin_addr.s_addr)))
moptions |= MULTICAST_TTL;
else
options |= F_HDRINCL;
}
For traceroute:
void
check_tos(struct ip *ip, int

Hi tech@,
For `-T' option explanation in netcat manual:
-T keyword
Change the IPv4 TOS value or the TLS options.
But in fact, the netcat code not only processes IPv4 but also IPv6:
if (Tflag != -1) {
if (af == AF_INET && setsockopt(s, IPPROTO_IP,
