Key-Based SSH Logins With PuTTY

Filed under
HowTos

This guide describes how to generate and use a private/public key pair to log in to a remote system with SSH using PuTTY. PuTTY is an SSH client that is available for Windows and Linux (although it is more common on Windows systems). Using key-based SSH logins, you can disable the normal username/password login procedure which means that only people with a valid private/public key pair can log in. That way, there is no way for brute-force attacks to be successful, so your system is more secure.

1 Preliminary Note
In this tutorial I use a Windows desktop to connect to a Linux SSH server (Debian Sarge, IP address: 192.168.0.100).

2 Install PuTTY, PuTTYgen, And Pageant On The Windows System
First we need to install PuTTY, PuTTYgen, and Pageant on our Windows system.

I reviewed Calibre back when it was at version 0.8.24 and the 1.0 version was nowhere in sight. Even back then, the software was chock-full of features and options. It was difficult to imagine that it could bring even more improvements to the table, but it did. In fact, it's safe to say that a large number of eBook readers crossed paths with Calibre at one point or another, and it's likely that most of those users found what they had been looking for.

Fedora Might Try A New Scheduling Strategy For Its Releases

It's no secret that Fedora has had a challenging time sticking to their release schedules for a long time. With taking care of blocker bugs, Fedora Linux releases tend to frequently slip -- with Fedora 21 it's about two months behind schedule and we're just past the alpha stage. By the time Fedora 21 actually ships, Fedora 20 will have been at least twelve months old. However, a new release scheduling strategy might be tried starting with Fedora 22. Read more
