How To Install rubygem-net-telnet on CentOS 8
Introduction
In this tutorial we learn how to install rubygem-net-telnet on CentOS 8.
What is rubygem-net-telnet
Provides telnet client functionality. This class also has, through delegation, all the methods of a socket object (by default, a TCPSocket, but can be set by the Proxy option to new()). This provides methods such as close() to end the session and sysread() to read data directly from the host, instead of via the waitfor() mechanism. Note that if you do use sysread() directly when in telnet mode, you should probably pass the output through preprocess() to extract telnet command sequences.
We can use yum or dnf to install rubygem-net-telnet on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install rubygem-net-telnet.
