Using MTR for Linux network troubleshooting

Diagnosing the network in Linux

In case mtr is not installed, install it in Linux. You can use your own default package manager to do this:

#Debian/Ubuntu
apt-get install mtr
#CentOS
yum install mtr

Once the utility is installed, it is invoked with the command mtr: you need to specify the domain of the site or the IP of the server where you want to test access.

For example:

mtr google.com

To display true IP addresses instead of hostnames adjacency -n:

mtr -n google.com

Alternatively, use TCP SYN packets or UDP datagrams instead of standard ICMP requests:

mtr --tcp google.com mtr --udp google.com

If the -r and -c 100 keys are used, you can output the final result in a convenient form with the specified number of packets using the following command:

mtr -rn -c 100 google.com
