Today in this article, we shall cover the basics of telnet including how to use Telnet in Windows.

Today in this article, we will cover below aspects,

What is Telnet?

Telnet is an application protocol for bidirectional interactive text-oriented communication over the Internet or a local area network using a virtual terminal connection.

Main feature of Telnet

• In an 8-bit byte oriented data connection using the Transmission Control Protocol, user data is interspersed in-band with Telnet control information (TCP).

• Telnet gave users access to a remote host’s command-line interface.

• Telnet’s has some security problems when utilizing it over an open network like the Internet when it compared with SSH.

• Telnet was created in 1969 and standardized as Internet Engineering Task Force (IETF) Internet Standard STD 8, one of the early Internet standards and extended in RFC 855

Telnet is already available in Windows operating system and can be easily enabled by following the below-listed steps.

Steps to enable Telnet in Windows

1. Open Control Panel ->Go to Programs and Features (WIN+R and then enter control)

Alternatively, you can run appwiz.cpl in the windows search

2. Click on “Turn Windows features on or off“

Select the Telnet Client feature.

Once enabled click on Ok and you shall see below dialog box for successful configuration.

next, open the command prompt and just type telnet.

This will open a “Command prompt for Telnet client”.

You are all set to run the Telnet commands,

Telnet commands on windows

• c – close -> close current connection
• d – display -> display operating parameters
• o – open hostname [port] connect to hostname (default port 23).
• q – quit exit telnet
• set – set set options (type ‘set ?’ for a list)
• sen – send send strings to server
• st – status print status information
• u – unset unset options (type ‘unset ?’ for a list)
• ?/h – help print help information

For more details on the above commands please refer to this link.

Today in this article, we shall see how to run Redis on Windows. We shall run Redis Server and default available Redis client on Windows machine to verify Redis cache is configured correctly.

Today in this article, we will cover below aspects,

There are multiple ways by which you can install Redis on your Windows machine. Recently, I tried a few different ways, but I ran into a few issues with Redis version compatibility and other errors.

Finally, I choose to adopt WSL, which is a basic approach to run easily on the Windows subsystem for Linux.

What is WSL?

WSL is Windows Subsystem for Linux.

Benefits of WSL

• It allows developers to execute Linux environments on Windows without the need for virtual machines or other configurations.
• WSL gives you support for most of the command-line tools, utilities, and applications used on Linux example bash, ssh, git, apt.

Run Redis on Windows setup

Please follow below basic steps below.

Step 1: Enable Microsoft-Windows-Subsystem-Linux on the windows machine

The Enable-WindowsOptionalFeature cmdlet enables or restores an optional feature in a Windows image.

Run Powershell in Administrator mode and run the below command

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

If not used in admin mode might get the below error,

Above specify the running operating system on your local computer with the Online option

The above command should take a few minutes to enable this feature.

Please restart the machine for the configuration to be effective.

Step 3: Download and install Linux distros using Ubuntu/Debian

You can install Linux distros using the Ubuntu app available on the Microsoft store.

Ubuntu on Windows allows one to use Terminal and run Ubuntu command line utilities including bash, ssh, git, apt, etc.

• Debian GNU/Linux

• Ubuntu 18.04 

Install Debian GNU/Linux on Windows

OR

Install Ubuntu 18.04 on Windows

Once Ubuntu is installed successfully, please configure the default user account to run the required apt commands

Please run the below commands to get the latest updates if any,

> sudo apt-get update

> sudo apt-get upgrade

Install Redis Server and Client- Windows

Let’s install now Redi server now using the sudo apt command,

sudo apt-get install redis-server

For any issue please restart the Redis Server,

sudo service redis-server restart

Redis client validation – Windows

Command

SET key value [EX seconds|PX milliseconds|EXAT timestamp|PXAT milliseconds-timestamp|KEEPTTL] [NX|XX] [GET]

As we can see Redis port for Windows 6379 is used. Above we are setting a new key and retrieving the key from the cache.

That’s all, you are all set to use the Linux command on the window machine. Hope you find this useful.
