Parameters
host: The host that we wish to trace the route packets for.
ipv6: If a hostname is defined as the value of the 'host' parameter, use the hosts IPV6 address.
gateway: Tells traceroute to add an IP source routing option to the outgoing packet that tells the
network to route the packet through the specified gateway.
interface: Specifies the interface through which traceroute should send packets. By default, the
interface is selected according to the routing table.
first_ttl: Specifies with what TTL to start. (Minimum: 1, Default: 1)
max_ttl: Specifies the maximum number of hops (max time-to-live value) traceroute will probe.
(Minimum: 1, Default: 30)
port: Specifies the destination port base traceroute will use (the destination port number will be
incremented by each probe). A value of -1 specifies that no specific port will be used. (Minimum: -1,
Default: -1)
nqueries: Sets the number of probe packets per hop. A value of -1 indicated. (Minimum: 1, Default: 3)
src_addr: Chooses an alternative source address. Note that you must select the address of one of the
interfaces. By default, the address of the outgoing interface is used.
tos: For IPv4, set the Type of Service (ToS) and Precedence value. Useful values are 16 (low delay) and
8 (high throughput). Note that in order to use some TOS precedence values, you have to be super
user. For IPv6, set the Traffic Control value. A value of -1 specifies that no value will be used.
(Minimum: -1, Default: -1)
waittime: Determines how long to wait for a response to a probe. (Minimum: 1, Default: 5)
pausemsecs: Minimal time interval between probes. (Minimum: 0, Default: 0)
packetlen: Total size of the probing packet. Default 60 bytes for IPv4 and 80 for Ipv6. A value of -1
specifies that the default value will be used. (Minimum: -1, Default: -1)
debug: Enable socket level debugging.
dontfragment: Do not fragment probe packets.
icmp: Use ICMP ECHO for probes.
nomap: Do not try to map IP addresses to host names when displaying them.
bypass: Bypass the normal routing tables and send directly to a host on an attached network.
