You need to get a copy of a later Wireshark (version 2.4) on your CentOS 7 system, without needing to follow all the instructions in Building Wireshark 2.4.0 for Centos 7. Wireshark provides one of the widest used network analysis tools available.
Let’s go, you’re in a hurry..
Install a prebuilt .repo file
Now move it to the yum repositories directory
sudo mv wireshark.repo /etc/yum.repos.d/
sudo yum update
You should see entries for the wireshark repository included
Install Wireshark, accept the GPG key
yum install wireshark-qt
This will install the wireshark version using the Qt front-end as version 2.4.0 finally removes the GTK support.
You will receive a prompt as below, select Y only if the fingerprint matches.
