【网络诊断命令】Linux traceroute命令追踪网络数据包的路由途径

Linux traceroute命令用于显示数据包到主机间的路径, 相当于windows下的tracert 命令。

traceroute指令让你追踪网络数据包的路由途径，预设数据包大小是40Bytes，用户可另行设置。

tracerroute -h

Usage: traceroute [-FIldnrv] [-f 1ST_TTL] [-m MAXTTL] [-p PORT] [-q PROBES]

[-s SRC_IP] [-t TOS] [-w WAIT_SEC] [-g GATEWAY] [-i IFACE]

[-z PAUSE_MSEC] HOST [BYTES]

Trace the route to HOST

-F Set the don't fragment bit

-I Use ICMP ECHO instead of UDP datagrams

-l Display the TTL value of the returned packet

-d Set SO_DEBUG options to socket

-n Print numeric addresses

-r Bypass routing tables, send directly to HOST

-v Verbose

-m Max time-to-live (max number of hops)

-p Base UDP port number used in probes

(default 33434)

-q Number of probes per TTL (default 3)

-s IP address to use as the source address

-t Type-of-service in probe packets (default 0)

-w Time in seconds to wait for a response (default 3)

-g Loose source route gateway (8 max)

诠释：

语法（用法）

traceroute [-dFlnrvx][-f<存活数值>][-g<网关>...][-i<网络界面>][-m<存活数值>][-p<通信端口>][-s<来源地址>][-t<服务类型>][-w<超时秒数>][主机名称或IP地址][数据包大小]
