Linux traceroute command details how to use Linux traceroute command

The traceroute command allows you to track the route of network data packets. The default data packet size is 40 Bytes, which can be set separately.

Syntax

Traceroute [-dFlnrvx] [-f <survival value>] [-g <Gateway>...] [-I <network interface>] [-m <survival value>] [-p <communication Port>]

[-S <source address>] [-t <Service Type>] [-w <timeout seconds>] [host name or IP address] [packet size]

Parameter description:

• -D uses the Socket-level troubleshooting function.
• -F <survival value> sets the TTL value of the first detected data packet.
• -F: Do not disconnect the bits.
• -G <Gateway> You can set up to eight source route gateways.
• -I <network interface> use the specified network interface to send data packets.
• -I replace UDP data with ICMP response.
• -M <survival value> sets the TTL value of the maximum survival value of the detection data packet.
• -N directly uses the IP address rather than the host name.
• -P <communication Port> sets the communication port of UDP transmission protocol.
• -R ignores common Routing tables and directly sends data packets to the remote host.
• -S <source address> sets the IP address of the data packet sent from the local host.
• -T <Service Type> sets the TOS value of the detection data packet.
• -V displays the instruction execution process in detail.
• -W <timeout seconds> sets the time to wait for the return of the remote host.
• -X enables or disables the packet correctness test.
