Linux command Daquan Linux command Daquan

Linux traceroute command displays the data packets to the path between hosts.

traceroute command allows you to track the routing route network packets, the default packet size is 40Bytes, the user can set separately.

grammar 

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]

Parameter Description:

  • -d Use Socket-level debugging functions.
  • -f <survival value> Set survival value first detected packet TTL size.
  • -F Do not set off down bits.
  • -g <gateway> Sets the source routing gateway can have up to eight.
  • -i <network interface> sent data packet using a specific network interface.
  • -I Use ICMP Echo substituted UDP profile information.
  • -m <survival value> is set to detect the maximum packet size of the survival value of TTL.
  • -n directly use IP addresses instead of host names.
  • -p <communications port> Set the communications port UDP transport protocols.
  • -r ignore normal Routing Table, directly to the data packet to the remote host.
  • -s <source address> Setting the IP address of the local host sends the packet.
  • -t <service type> Set detection packet TOS values.
  • -v displays detailed execution instructions.
  • -w <timeout in seconds> Set the time to wait for the remote host in return.
  • Verifying the correctness -x turn on or off the packet.
