Linux traceroute command

Linux Command Manual

The Linux traceroute command is used to display the path between packets and hosts.

The traceroute command allows you to trace the route of network packets, with the default packet size being40Bytes, users can set it 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 Use the debugging function at the Socket level.
• -f<survival value> Set the size of the TTL (Time to Live) for the first detected packet.
• -F Set the non-disconnect position.
• -g<gateway> Set the source route gateway, up to8number.
• -Use the specified network interface to send packets.
• -I Use ICMP echo instead of UDP data information.
• -m<survival value> Set the maximum survival value TTL for packet detection.
• -n Use IP address directly instead of host name.
• -p<communication port> Set the communication port for UDP transmission protocol.
• -r Ignore the normal Routing Table and send packets directly to the remote host.
• -s<source address> Set the IP address of the local host to send packets.
• -t<service type> Set the TOS value of the packet to be detected.
• -v Display the detailed execution process of the command.
• -w<timeout seconds> Set the time to wait for the remote host to respond.
• -x Enable or disable packet correctness check.
