What Is PuTTY?


Putty is a free and open-source terminal emulator supporting SSH, Telnet and Serial ports. Users can use Putty to easily manage remote devices as well as perform system administration tasks; users also have the power to personalize interfaces and keyboard shortcuts with this terminal emulator.

After installing the software, users can launch it by double-clicking an icon or from the Start menu. A window will open with two tabs: an initial configuration panel on the left and one for saving session profiles on the right.

It is a free and open-source terminal emulator

PuTTY is a free and open-source terminal emulator, serial console, and SSH client application designed for use on Windows operating systems. It enables users to connect remotely using network protocols like SSH, Telnet, Rlogin and Raw Socket connections; saving connection configurations as sessions for easy access is also supported by PuTTY.

PuTTY was initially developed for Microsoft Windows but has since been ported to other Unix-like platforms. PuTTY provides many features, such as connecting to multiple servers simultaneously, managing SSH keys and configuring keyboard settings, creating custom window sizes, controlling scrolling speeds and customizing colors of text in windows – and more!

This program, written in C, was released for download and use free of charge in 1996 and remains free today, though commercial use requires a license agreement. As its code is open source and developers encourage user contributions for improvements or patches; additionally it offers a bug bounty program to reward developers who identify bugs.

PuTTY stands out as an indispensable communication solution due to its SSH support, which ensures all communications remain encrypted. This feature can be particularly valuable for administrators needing remote access for managing networks; PuTTY allows them to work as though physically present at each machine’s console.

PuTTY stands out from other network protocols by supporting many, such as SFTP and SCP. This makes it a top choice for connecting remotely to Linux or BSD systems; additionally it makes for seamless interaction when working with raw Internet serial connections, like those found on Raspberry Pis.

Discovery, the supercomputer at New Mexico State University (NMSU), is located on campus, but students, faculty, and staff can log on remotely via PuTTY to use its memory and software resources – giving them access to programs like MATLAB without installing them on their own computers. Furthermore, PuTTY allows access to Discovery’s computational resources over the internet that are otherwise inaccessible via campus networking.

It supports SSH

SSH stands for Secure Shell and allows two remote systems to communicate securely over a network. To operate, both clients and servers need authentication from both parties – usually the client using an SSH key pair, while servers verify its authenticity by comparing it with an RSA fingerprint file on which all SSH keys exist; once authenticated, cached keys will be cached on servers until required again by clients or as part of a passphrase set up on them by clients for later use.

PuTTY supports SSH connections using both private and public keys, offering various features like logging, cursor formatting, keyboard formatting, alert sound alert sound notification resizing terminal window changing mouse buttons actions configuring proxy servers as well as auto logging/storing session profiles for future use.

Once PuTTY is installed, it’s easy to launch by either clicking its desktop icon or from Windows Start menu. A configuration window will appear with hostname or IP address fields on either side, as well as additional options in the center. At the lower right corner is an area for saving session specifications for easily connecting to commonly visited servers.

If you have an SSH key, click on the Auth tab of PuTTY configuration window to set up public key authentication. Provide remote hostname/IP address along with SSH as the connection type; save session to store this configuration; this way it won’t be necessary for future login attempts! This way you’ll avoid typing out hostname/password combinations each time!

Puttygen can help you generate and load an SSH key into PuTTY configuration window, using a passphrase created with Puttygen to prevent malicious software from guessing it. Furthermore, this passphrase must be memorable so that in case of password forgetfulness you have something you can remember instead.

SSH is an easy and flexible method of connecting to Linux-based servers on DigitalOcean, making it the go-to solution for developers testing new code in real-world conditions. DigitalOcean also offers managed products like Cloudways and App Platform that provide preconfigured software stacks on Droplets automatically.

It supports telnet

PuTTY’s Telnet feature allows users to securely connect to remote servers. This is useful for system administrators performing software updates or troubleshooting on headless environments; network engineers configuring/monitoring remote devices; file transfer; terminal emulation etc. It is also beneficial for file transfer. PuTTY can serve multiple other purposes including file transfer and terminal emulation.

To enable Telnet, toggling on its protocol button in the Session configuration panel (see section 4.1.1) will launch PuTTY’s Telnet Wizard which displays a prompt asking for host name and port details before offering up its connection options – once completed click “Open” to make an instantaneous connection! Since all settings for sessions saved within PuTTY will also transfer across machines if you copy over your program from one machine to the other, including saved sessions that are stored locally on it.

Debugging sessions is made simpler by logging all output to a text file. To log output, click the ‘Log All Session Output’ button within the ‘Session’ panel.

PuTTY also supports secure alternatives to telnet such as Rlogin and SSH; these protocols offer more secure connections between the host computer and users. You can configure security options of these connections using PuTTY’s “Session” panel.

If you want to use the NMSU supercomputer Discovery, for example, using PuTTY you can log on and run your MATLAB code directly on its server without taking up space on your own machine.

PuTTY can also be customized to fit the unique needs of individual users, including font size and colors adjustments, mouse behavior customization and keyboard shortcut settings. Users can also create multiple sessions that they save as profiles so that when connecting to similar servers frequently they don’t waste time switching profiles each time. Furthermore, users have the ability to choose whether or not their window closes upon exiting PuTTY sessions.

It is customizable

No matter if you’re using PuTTY to manage a server, configure network devices, or access remote computers – it is crucial that it meets your unique requirements. With its numerous configuration options and settings allowing for customization of font size and colors as well as keyboard shortcuts and mouse behavior settings – customizing PuTTY for yourself can make using it an enjoyable experience, especially over prolonged sessions of use.

PuTTY is an application that lets you connect to servers using SSH, Telnet and Rlogin network protocols as well as serial ports to connect devices like routers and switches. Furthermore, it supports X11 forwarding which enables graphical programs run remotely to be displayed locally on another system.

By selecting the menu item “Options”, the program settings can be tailored to your personal needs. Here, you can set your background color, encoding, terminal window size and font preferences; as well as changing other features such as scrolling speed. In addition, keystrokes like backspace and home keys may also be disabled and cursor positioning adapted according to personal needs.

PuTTY also allows users to easily select and copy text directly from its program by simply dragging their mouse across the session window, with all copied texts saved directly into their clipboard (CTRL + V). This feature can come in very handy if they need to paste them directly into another program.

PuTTY allows you to customize its windows and menus by choosing “Colors” in its Options Menu Item. Simply choose your color of choice and use Modify button; for instance, to change ANSI blue shades using sliding the black arrow until you find something suitable to your eyes. Furthermore, saving these settings using Configure Menu Item will save current font and color settings until next time you launch PuTTY program.
