Are you trying to install a tool that helps in analyzing the network traffic? A good option is to install WireShark on CentOS.

It helps in troubleshooting common problems which include dropped packets, latency issues, and malicious activity on the server.

Here at Bobcares, we often receive requests to enable WireShark as a part of our Server Management Services.

Today, let’s discuss how to install WireShark on CentOS and see how our Support Engineers fix its related errors.

What is WireShark and why it is important to install?

Before getting into the installation part let’s briefly discuss what WireShark is. Also, let’s see why it is necessary on a server.

WireShark is a network analyzer tool. From a security perspective, it is a very important tool that provides the necessary details of the traffic.

Also, it captures the network packets and provides their details.

Moreover, it provides the necessary tools to dig deep into the traffic and find the root cause of the problem.

How we install WireShark on CentOS

Let’s move on to the installation part and see how our Support Engineers install it on CentOS.

Before installing it let’s make sure all the dependencies are available. We install the dependencies using the command:

$ yum install gcc gcc-c++ bison flex libpcap-devel qt-devel gtk3-devel rpm-build libtool c-ares-devel qt5-qtbase-devel qt5-qtmultimedia-devel qt5-linguist desktop-file-utils

In Linux, the WireShark is available directly from the distribution’s repositories. So we can easily install it via yum.

$ sudo yum install wireshark wireshark-qt

Common Errors with WireShark CentOS

Having a decade of experience in managing servers, our Dedicated Engineers are familiar with the WireShark errors.

Now, let’s see a few errors that we commonly receive in WireShark and how our Support Engineers fix them.

Out of Memory error

This is one of the annoying problems we come across. Usually, Wireshark will automatically terminate if it runs out of memory.

Recently, we received this error from one of our customers.

So to fix this error, our Support Engineers increased the memory of the server.

Finally, this fixed the error.

Permission Denied error

This is one of the common errors that we receive after the installation. In case, if we receive this error when starting the WireShark as a local user then we can simply start it as root.

This will quickly fix the error.

Else, we can add the local user to the WireShark group.
