traceroute : print the route packets trace
[SYNOPSIS] traceroute OPTION HOST
OPTION
-4 Use IPv4
-6 Use IPv6
-d Enable socket level debugging
-F Do not fragment packets
-f TTL Start from the first_ttl hop (instead from 1)
-g GATE Route packets through the specified gateway (maximum 8 for IPv4 and 127 for IPv6)
-I Use ICMP ECHO for tracerouting
-T Use TCP SYN for tracerouting (default port is 80)
-i DEV Specify a network interface to operate with
-m TTL Set the max number of hops (max TTL to be reached). Default is 30
-N QUERY Set the number of probes to be tried simultaneously (default is 16)
-n Do not resolve IP addresses to their domain names
-p PORT Set the destination port to use. It is either initial udp port value for "default" method (incremented by each probe, default is 33434), or initial seq for "icmp" (incremented as well, default from 1), or some constant destination port for other methods (with default of 80 for "tcp", 53 for "udp", etc.)
-t TOS Set the TOS (IPv4 type of service) or TC (IPv6 traffic class) value for outgoing packets
-q QUERY Set the number of probes per each hop. Default is 3
-r Bypass the normal routing and send directly to a host on an attached network
-s SOURCE Use source src_addr for outgoing packets
-z WAIT Minimal time interval between probes (default 0). If the value is more than 10, then it specifies a number in milliseconds, else it is a number of seconds (float point values allowed too)
-e Show ICMP extensions (if present), including MPLS
-A Perform AS path lookups in routing registries and print results directly after the corresponding
-M MODULE Use specified module (either builtin or external) for traceroute operations. Most methods have their shortcuts (`-I' means `-M icmp' etc.)
-O OPTS Use module-specific option OPTS for the traceroute module. Several OPTS allowed, separated by comma. If OPTS is "help", print info about available options
--sport=NUM Use source port num for outgoing packets. Implies -N 1'
--fwmark=NUM Set firewall mark for outgoing packets
-U Use UDP to particular port for tracerouting (instead of increasing the port per each probe), default port is 53
-UL Use UDPLITE for tracerouting (default dest port is 53)
-D Use DCCP Request for tracerouting (default port is 33434)
