Exercise 1 - Administering Windows Servers using Telnet
Telnet is an application protocol that enables bidirectional text-based communication among the devices on a network. Telnet offers a user-interface that enables a user to access various devices on the network remotely. In addition, you can use telnet to perform remote configuration and maintenance of devices. Telnet supports devices on WANs (such as Internet) as well as LANs (corporate or home network). By default, the telnet servers listen for incoming connection requests on port 23. Telnet operates on the server-client setup.
In this exercise, you will use Telnet to perform some basic administrative work like creating users and security groups on a Windows server.
Exercise 2 - Administering Kali Linux using VNC and SSH
Virtual Network Computer or VNC is a graphical desktop sharing program that allows you to remotely control another computer. This tool transmits the keyboard and mouse movements on your computer to a remote system, and responds with graphical screen updates. All this communication takes place over a network. 5900 is the default port for VNC.
Many VNC variants are available for free public download. You can explore these to select the one most suited to your requirement(s).
Similarly, Secure Shell or SSH is an encrypted network protocol for initiating text-based shell sessions on remote systems. SSH allows a user to run commands on a machine’s terminal window without being physically present at the machine. SSH is similar to telnet. The difference being that SSH provides a secure channel over an insecure network.
In this exercise, you will use TigerVNC (a VNC app) and Putty (an SSH app) to remotely administer PLABKSRV01 - a Kali Linux device.
Exercise 3 - Administering Servers using RDP
Remote Desktop Protocol (RDP) is a client-server based protocol that provides a user with a graphical user interface (GUI) to connect to another computer over a network connection. RDP is designed for secure communications among devices with either the Windows Terminal Services Client or the Windows Terminal Services Server. This protocol supports devices connected on the wide range of network sizes - from a WAN (such as Internet) on one end to a LAN (say, a home network) on the other. RDP uses port 3389 by default.
