Traceroute Flags -p -q
-p Port Sets the base UDP port number used in probes. The default is 33434. The traceroute command depends on an open UDP port range of base to base + nhops - 1 at the destination host. If a UDP port is not available, this option can be used to pick an unused port range.
-q Nqueries Specifies the number of probes the traceroute command sends at each Max_ttl setting. The default is three probes.
