how to perform traceroute

Traceroute command, tracerouteWith traceroute, we can know the path from your computer to the host on the other end of the Internet. Of course, the path for each packet to arrive at the same destination from a certain source may be different, however, most of the time the routes are the same. In linux, traceroute is called tracert in MS Windows.

Mtr (My traceroute) is a Network Diagnostics tool that incorporates ping and traceroute into a program. The MTR provides two interfaces: a ncurses interface that is useful for using MTR from a Telnet session, and a GTK + interface for X (provided in the MTR-GTK software package).MTR use1, MTR command line toolsMTR use is relatively simple, please refer to MTR's man page for detailed usage.[root@ts3-142 ~]#

through the router-1, when reaching router-2, the TTL value is a value of 0 , which is discarded, returns the icmp-timeout packet to the requesting host; Continue to repeat, each received a return icmp-timeout packet, then continue to emit a TTL value of +1 UDP packet; 3, in this way, after 4 routers, ttl=5 UDP packets, after the mountains and rivers, finally came to the destination host, we may feel that the destination host will gladly accept this UDP packet, But actually not, the destination

also gives us a chance to view the route from the host to the target host. This is because, when the ICMP ping request datagram passes through a vro, The vro will put its own IP address in the report. The target host will copy the IP address list to the host in response to the ICMP packet. However, in any case, the list of routes that the IP header can record is very limited. To observe routing, we still need to use a better tool, that is, traceroute

host's u d p module generates an I c m p packet with the "port inaccessibility" error. In this way, the traceroute program needs to distinguish whether the received I c m p packets are time-out or the ports are inaccessible, to determine when to end (when the destination host is received when the port cannot reach the ICMP packet ). The traceroute command uses the UDP high port to send multiple detection

, such as sf.net, if you are interested. Then you can see packet loss, the program runs for a longer time.Ping also gives us a chance to view the route from the host to the target host.

The relevant knowledge about the Linux traceroute command is as follows: Through traceroute we can know the information from your computer to the Internet on the other end of the host is what path to go. Of course the path to a certain same destination (destination) may be different every time a packet is reached by a certain same starting point (source), but basically the route is the same for most of the

) ip addresses is 9. -K computer-list Route data packets using the computer list specified by computer-list. The maximum number of ip addresses allowed by consecutive computers to be separated by intermediate gateways (strictly source routes) is 9. -W timeout Specify the timeout interval, in milliseconds. Destination-list Specify the remote computer to be pinged. C: //> ping ds.internic.net Pinging ds.internic.net [192.20.239.132] with 32 bytes of data: (192.20.239.132 his IP address) Reply from

Ping, tracert, traceroute, and netstat command to view the ubuntu running status command 1. route to view and set the route information for Linux 2. ping: network connectivity check example: ping 192.168.0.1 parameter:-c is used to specify the number of ping responses. Example: ping-c 4 192.168.0.1 the specified number of responses is 4 3. traceroute is used to analyze the network topology format:

Command for viewing Ubuntu running status 1. route to view and set the route information for Linux 2. ping: network connectivity check example: Ping 192.168.0.1 parameter:-C is used to specify the number of Ping responses. Example: Ping-C 4 192.168.0.1 the specified number of responses is 4 3. traceroute is used to analyze the network topology format: Traceroute Remote Host IP address or domain name 4. net

By traceroute we can know what path the information from your computer to the other end of the Internet host is walking. Of course, each time a packet arrives at a similar destination (destination) by a similar starting point (source), the path may be different, but basically the route is the same.Linux systems, which we call traceroute, are tracert in MS Windows.
