Like many Linux users, I use Guarddog as a frontend to my iptables firewall. At some point, I noticed that Guarddog started acting strangely. Every time I restarted my computer, all internet traffic was blocked (both in and out). The only way to fix this situation was to open Guarddog and press “Apply” (without doing any changes). While it was annoying, it didn’t bother me much because I used to restart my computer about once a month. But few days ago, I decided to solve this problem once and for all.

svn switch fails because unversion files exist in the working copy, and the need to erase them comes up. This is also true when updating to an old revision (usually one that misses directories that exist in the head revision), doing some work (like compiling), and then trying to update back to the head revision. Subversion (SVN) will fail complaining that directories/files already exist.

In this tutorial I will explain how to create a local Subversion (SVN) repository, intended for a single user. I assume that you already know the benefits of keeping track of old revision of projects or important documents such as a resume or a thesis you have been writing. Subversion offers you a very convenient yet strong method to do so, and the easiest way to do so with Subversion (SVN) is to create a local, home, repository intended for a single user – you.

spass is a secure password generation tool.
spass was designed under the assumption that a password generator is as good as its random number generator, so
spass uses the
Random class, a
/dev/random based cryptographically strong random number generator class. As always, I tried to make the command-line interface as user-friendly as possible (as much as a command-line interface can be friendly).
spass – A Secure Password Generator Utility
In this post I will walk you through generating RSA and DSA keys using
ssh-keygen. Public key authentication for SSH sessions are far superior to any password authentication and provide much higher security.
ssh-keygen is the basic way for generating keys for such kind of authentication. I will also explain how to maintain those keys by changing their associated comments and more importantly by changing the passphrases using this handy utility.
