This article mainly introduces how to use the traceroute command in the Linux system, the article is very detailed, has a certain reference value, interested friends must read it!

Use the traceroute command in the Linux system to know the path we sent your computer to the host on the other side of the Internet, allowing you to track the route of network data packets. The default packet size is 40Bytes, which the user can set separately.

The syntax traceroute [- dFlnrvx] [- f] [- g...] [- I] [- m] [- p] [- s] [- t] [- w] [hostname or IP address] [packet size] parameter states that-d uses Socket-level troubleshooting.

-f sets the size of the survival value TTL of the first detection packet.

-F setting do not leave the break bit.

-g set source routing gateways. A maximum of 8 can be set.

-I send out packets using the specified network interface.

-I use ICMP responses instead of UDP data information.

-m sets the size of the maximum survival value TTL of the detection packet.

-n directly use the IP address instead of the host name.

-p sets the communication port of the UDP transport protocol.

-r ignores the normal Routing Table and sends the packet directly to the remote host.

-s sets the IP address of the packet sent by the local host.

-t sets the TOS value of the detection packet.

-v shows the execution of the instruction in detail.

-w sets the time to wait for a return from the remote host.

-x turns on or off the correctness check of the packet.

The case demonstrates the use of multiple commands

Traceroute-n-m 5-Q 4-w 3 www.baidu.com

Description:-n displays the IP address, does not check the hostname, and-m sets the hop count

-Q 4 each gateway sends 4 packets-w sets the waiting response time for outgoing probe packets to 3 seconds

The basic UDP port setting used by the probe packet is 6888

Bypass the normal routing table and send it directly to the network-connected host
