traceroute checks the program name when it is called.
When the name of the program is tracert, it uses ICMP,
traceroute-2.0.12 does *NOT* create any symlink "tracert",
the RPM packagers does.
For your curiousness, I include the function that does the check in
traceroute[1]
The symlink has been dropped by Redhat packagers so
I think in the next versions of CentOS - which is a sub-stream from
Fedore project -
will reflex the change[2]
[1] traceroute-2.0.12/traceroute/traceroute.c:164
/* Set initial parameters according to how we was called */
static void check_progname (const char *name) {
const char *p;
int l;
p = strrchr (name, '/');
if (p) p++;
else p = name;
l = strlen (p);
if (l <= 0) return;
l--;
if (p[l] == '6') af = AF_INET6;
else if (p[l] == '4') af = AF_INET;
if (!strncmp (p, "tcp", 3))
module = "tcp";
if (!strncmp (p, "tracert", 7))
module = "icmp";
return;
}
