Click the Default Settings option in the Saved Sessions area. Click the Save button. Now, whenever you use the Cunix shortcut, connect from your web browser, or create a new profile, these settings will be used for your environment.

Type the hostname cunix. To save a session, enter the hostname in the Hostname text box and enter the name you want to save that session as in the Saved Sessions, text box and click Save. Select a saved session by highlighting a previously saved session and click Load and then Open. Back to Top. Other SSH clients. Using the terminal on Windows. PuTTY user manual. Note that use of SSH1 is not recommended for security reasons.

Practically all devices support SSH2 these days. No scripting support, but can be used together with WinSCP. The main feature of the product is the terminal window. It has good terminal emulation, good configurability, and good support for different cryptographic algorithms. The user interface does not include an integrated file transfer client. These can be used for file transfers. However, most non-technical users are not willing to use a command line. Tectia SSH , for example, has offered fully integrated file transfer capability since Having two software packages, switching between them to do operations, and managing profiles and logins for both is extra trouble.

The keys are stored in. The PuTTYgen tool can be used for generating new keys and converting between. It is common for hackers and malware to collect SSH keys when penetrating an organization. This happened, for example, in the infamous Sony breach. Managing SSH keys properly is important. PuTTY grew out of a telnet client. It still supports the telnet protocol.

However, very few devices use telnet these days. Its use is not recommended for security reasons. Telnet sends all user names and passwords in the clear.

It is very easy to listen to network traffic and steal user names and passwords from telnet traffic. By mids, such password sniffing attacks had become the largest security problem on the Internet. That was the very problem SSH was designed to solve. Compromised routers, switches, or ARP proofing attacks can also be used to inject arbitrary commands into telnet sessions. There is a separate version of the software, called PuTTYtel , for countries that do not allow any use of encryption.

However, SSH is now used in all countries, officially or unofficially. Most systems can no longer be managed without encryption. Even the most oppressive countries need to secure their systems somehow.

There cannot be cybersecurity in a networked environment without encryption. PuTTY also supports connecting to serial ports and raw sockets. These can sometimes be useful for debugging purposes and for working with some legacy devices. For example, in kernel development access via a serial port is still sometimes the best way to debug a panic that causes an immediate reboot, as it provides a way to see the boot messages. Version 0.
