![]() ![]() mtr -m 35 216.58.223.78 Set the size of the packet usedīy testing the quality of the network, we will be able to set the packet size. To do this we use -m followed by the value that interests us. ![]() With this we will be able to probe between the local system and the remote machine. We will be able to specify a maximum number of jumps. mtr -i 2 Specify the maximum number of jumps This can be changed by specifying a new interval between requests changing the value using -i. The default interval between ICMP ECHO requests is one second. mtr -o "LSDR NBAW JMXI" 216.58.223.78 Interval between ICMP ECHO requests It can see the MTR man page for the meaning field labels. This is possible thanks to the -o option as shown below. We will also be able to organize the output fields in the way that interests us the most. mtr -r -c 4 > mtr-reporte Organize the output fields Since the statistics are printed on standard output, we will be able to redirect them to a file for further analysis. We can use this option together with -c to specify the number of pings. To do this, we will use -r, which is a useful option to generate statistics on network quality. This program can be configured in report mode. If we look at the Snt column, once the specified number of pings is reached, the live update stops and the program exits. To limit the number of pings to a specific value and exit MTR after those pings, we'll use -c. If we are interested in MTR showing both host names and IP, we will only have to use -b: mtr -b Limit the number of pings For this we will only have to use -n as shown below: We will be able to force MTR to show IP addresses instead of host names. This command will show us a traceroute report updated in real time, until we close the program, pressing q or Ctrl + C. ![]() The simplest example we can use with MTR is to supply the domain name or IP address of the remote machine as an argument, for example or 216.58.223.78. Sudo apt install mtr Some examples of using MTR We will only have to open a terminal (Ctrl + Alt + T) and write in it: If you can't find MTR installed, you can install it on Ubuntun using the default package manager. We will find this tool pre-installed on most Gnu / Linux distributions and it is quite easy to use. 2.7 Specify the maximum number of jumps.2.6 Interval between ICMP ECHO requests.A sudden increase in packet loss or response time can be a sign of a bad connection, an overloaded host, or even a man-in-the-middle attack. When executing the program, ICMP packets are sent adjusting the time to live (TTL), to see the series of jumps that the packet makes between the origin and the destination. These are updated in real time, by default. ![]() It will also be possible to determine the path to a remote machine while printing the response percentage, as well as the response times of all network hops between the local system and the remote machine.ĭuring the course of this operation, MTR generates some useful statistics on each machine. From the host where MTR is running to a user-specified target host. Like traceroute, this program prints information about the path taken by packets. It then pings each one to determine the quality of the link to each machine. First you set the address of each network hop between the hosts. Once MTR is running, it will explore the network connection between the local system and a remote host that we specify. It is a simple and multiplatform program that combines the functionality of the traceroute and ping programs in a single tool. It is a network analysis tool and that we are going to use from the command line. In the next article we are going to take a look at MTR. ![]()
