Can you explain ping and tracert




















Traceroute, like ping , is considered to be lower priority compared to other traffic, so RTT values aren't guaranteed. There is a second caveat with traceroute that you should be aware of: Traceroute shows you the path from the source to the destination, but this does not mean that the reverse is true. In fact, there is no current way to identify the path from the destination to the source without running a second traceroute from the destination.

Keep this in mind when troubleshooting path issues. Netstat is an indispensable tool that shows you all of the network connections on an endpoint. That is, by invoking netstat on your local machine, all of the open ports and connections are shown.

This output includes connections that are not completely established as well as connections that are being torn down:. The output above shows several different ports in a listening state as well as a few established connections. For listening ports, if the source address is 0. If there is an IP address instead, then the port is open only on that specific interface.

The established connections show the source and destination IPs as well as the source and destination ports.

The Recv-Q and Send-Q fields show the number of bytes pending acknowledgment in either direction. Netstat also has a number of switches that can be used to view other information, such as the routing table or interface statistics. Both IPv4 and IPv6 are supported: There are switches to limit to either version, but both are displayed by default.

In recent years, netstat has been superseded by the ss command. You can find more information on the ss command in this article by Ken Hess. As you can see, these tools are invaluable when troubleshooting network issues. As a network or systems administrator, I highly recommend becoming intimately familiar with these tools. Using Ping Ping is a network utility used to see if the end user can reach other devices connected to the internet. To ping a device, proceed as follows.

Example: a successful Ping The following example shows the screen display after a successful ping attempt, where four packets were sent, and four packets received.

Example: a longer test Unfortunately, a sample set of four pings is not suitable for detecting packet loss, so we need to run a longer test. We don't need to view every ping, just the final result, which will look like this: As you can see in this test we dropped two packets but, due to the large sample size, this is negligible and is well within working parameters.

Using PathPing This network utility is a more advanced version of the Ping tool, which performs a ping to each hop along the route to the destination unlike Ping, which just pings from the originating device to the destination device. To PathPing a device, proceed as follows. Understanding PathPing results The advantages of PathPing over Ping and Traceroute are that each node is pinged as the result of a single command, and that the behaviour of nodes is studied over an extended time period, rather than the default ping sample of four messages, or default traceroute single route trace.

Example: successful pathping In the example, there were five hops along the route from the origin, Example: failed pathping The example illustrates some of the different results you might encounter.

Looking at hop 3, No packets have been dropped on hop 3, but it does have an abnormally high ping response time of ms. Looking at hop 4, As you can see this hop has not responded to any pings sent to it, but has not dropped any pings sent through it. Looking at hop 9, Everything on hop 5 to 8 is fine and everything looks normal, but hop 9 does not. Close Request a Demo.

By sending out datagrams with increasing TTL values and watching where the time to live exceeded datagrams come from one can produce a "map" of the "hops" that the outbound datagram moved through, along information about how long it took for the datagram to round-trip.

Think of ping like sonar pings on a submarine. You send packets to a particular host, and receive packets back. It's letting you know that host is running and responding to ICMP ping traffic. If it doesn't respond, it's either down or configured not to respond to pings, or there are other connection issues between you and the host either outgoing or incoming.

Tracert shows you the path that packets take from your local system to a remote host. You see the response time to each step along the way, because each datagram has a TTL time-to-live that's one hop longer than the previous one. This can be used to troubleshoot connection problems, as you can localize the source of your issues. Tracert lists the places that a message passes from source to destination. Ping only says the computer destination is answering "yes, I'm here.

While gaming ping comes into play to see the latency issue 1. Traceroute is a utility different on different platforms. Traceroute works by tracking packets sent by your pc to the destination server. Traceroute measures how many hops the packets take to reach the host and how long each hop takes it also determines the exact path taken by the packets.

Windows comes with included utility of Traceroute that can be accessed via the command prompt. On the other hand traceroute will help you to detect the exact point where the problem is occurring. Traceroute is used for video conferencing to debug the slowness in the hops.
