SSH login without Password

Written on November 14th, 2009 at 00:44 am by chia

Alright! So this one day, I'm talking to a friend. She's telling me about this real cool movie she heard about...2012 or something (which btw... WATCH! ). Now I'm also typing my password on an ssh server, and I happen to mistype. Now I have a feeling I've done so, so I press Backspace till I think nothing could ever have lasted here and type again. My lucky day it was, for I happen to mistype again. That was when it hit me! There's gotta be a way around this password thingy. This is why I love being a Linuxer. There's always a way out of everything!!!

But a forthcoming paper by an Electronic Frontier Foundation technologist suggests that Cookies are not be the only way to identify users, a combination of various information about the system and software collected from the browser are enough to uniquely identify a user.

Written on May 5th, 2010 at 20:28 pm by chia

The increased hacking attempts these days convinced me that password alone won't save my system from the attackers out there. For those of you who think that your system is safe because of some complex password, then think twice, because there is always a chance that a brute force attack from some dedicated server(s) might break it. A good password is a decent start, but its definitely not the end. In this tutorial, I will tell you some ways to make your ssh login more secure by making simple changes to the sshd_config file.
