List of content you will read in this article:
For example, we can specify the complete network Fping (192.168.0.1/24 Class C Network). As mentioned, it will send a Fping request to the host and move to another target host. This works like a round-robin. Unlike ping, fping is meant for basic scripting.
If you want Fping, you will need to install Fping packages separately as this doesn’t come together with the Operating System.
How to Install Fping on CentOS 7
First, download fping source package to your Linux server (the latest version is 3.10):
wget http://fping.org/dist/fping-3.10.tar.gz
To install the fping application, follow the steps below:
tar -xvf fping-3.10.tar.gz
cd fping-3.10
./configure
make
make install
You can compile fping with support for IPv6 addresses follow the next steps:
./configure --prefix=/usr/local --enable-ipv4 --enable-ipv6
make
make install
That's it! You have successfully installed fping on your CentOS server. Now for the next section of the article, we will go through some of the basic use cases of the fping command!
