How To Install tcping on Fedora 34

tcping is Check of TCP connection to a given IP/Port

Introduction

In this tutorial we learn how to install tcping on Fedora 34.

What is `tcping`

tcping does a TCP connect to the given ip/port combination. The user can specify a timeout in seconds. This is useful in shell scripts running in firewalled environments. Often SYNs are just being dropped by firewalls, thus connection establishment will be retried several times (for minutes) until a TCP timeout is reached. With tcping it is possible to check first if the desired port is reachable and then start connection establishment.

We can use yum or dnf to install tcping on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install tcping.
