Wireshark on CentOS 7 (TL;DR version)

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..

1. Install a prebuilt .repo file

   wget https://www.1310nm.net/repository/CentOS/7/wireshark.repo
   Now move it to the yum repositories directory
   sudo mv wireshark.repo /etc/yum.repos.d/

2. Update yum

   sudo yum update

   You should see entries for the wireshark repository included

3. 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.
   Retrieving key from https://www.1310nm.net/repository/RPM-GPG-KEY-publisher@1310nm.net
Importing GPG key 0x8B4AE102:
Userid : "Package Publisher (Package Publisher @ thirteen-ten nanometer networks) <publisher@1310nm.net>"
Fingerprint: c963 6096 c244 b68f 5306 031a c22c 2e77 8b4a e102

Is this ok [y/N]:

4. Run Wireshark

   From a command-line, wireshark, or from the menu, Applications|Internet|Wireshark.

Done.
