本文主要是介绍Linux下traceroute的安装和使用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
traceroute是跟踪数据包到达网络主机所经过的路由工具。其原理为试图以最小的TTL发出探测包来跟踪数据包到达目标主机所经过的网关，然后监听一个来自网关ICMP的应答。发送数据包的大小默认为40个字节。
yum install -y traceroute

Default is 30-N squeries --sim-queries=squeriesSet the number of probes to be triedsimultaneously (default is 16)-n Do not resolve IP addresses to their domain names-p port --port=port Set the destination port to use. It is eitherinitial udp port value for "default" method(incremented by each probe, default is 33434), orinitial seq for "icmp" (incremented as well,default from 1), or some constant destinationport for other methods (with default of 80 for"tcp", 53 for "udp", etc.)-t tos --tos=tos Set the TOS (IPv4 type of service) or TC (IPv6traffic class) value for outgoing packets-l flow_label --flowlabel=flow_labelUse specified flow_label for IPv6 packets-w waittime --wait=waittimeSet the number of seconds to wait for response toa probe (default is 5.0). Non-integer (floatpoint) values allowed too-q nqueries --queries=nqueriesSet the number of probes per each hop. Default is3-r Bypass the normal routing and send directly to ahost on an attached network-s src_addr --source=src_addrUse source src_addr for outgoing packets-z sendwait --sendwait=sendwaitMinimal time interval between probes (default 0).If the value is more than 10, then it specifies anumber in milliseconds, else it is a number ofseconds (float point values allowed too)-e --extensions Show ICMP extensions (if present), including MPLS-A --as-path-lookups Perform AS path lookups in routing registries andprint results directly after the correspondingaddresses-M name --module=name Use specified module (either builtin or external)for traceroute operations. Most methods havetheir shortcuts (`-I' means `-M icmp' etc.)-O OPTS,... --options=OPTS,...Use module-specific option OPTS for thetraceroute module. Several OPTS allowed,separated by comma. If OPTS is "help", print infoabout available options--sport=num Use source port num for outgoing packets. Implies`-N 1'--fwmark=num Set firewall mark for outgoing packets-U --udp 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 portis 53)-D --dccp Use DCCP Request for tracerouting (default portis 33434)-P prot --protocol=prot Use raw packet of protocol prot for tracerouting--mtu Discover MTU along the path being traced. Implies`-F -N 1'--back Guess the number of hops in the backward path andprint if it differs-V --version Print version info and exit--help Read this help and exit
Arguments:
+ host The host to traceroute topacketlen The full packet length (default is the length of an IPheader plus 40). Can be ignored or increased to a minimalallowed value实例参考：参考
