Installing And Using OpenVZ On CentOS 5.2

Post date: July 31, 2008, 11:07 Category: Installing Views: 4844 Comments
Tutorial quote: In this HowTo I will describe how to prepare a CentOS 5.2 server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

Apple's G5 versus x86, Mac OS X versus Linux

Post date: June 4, 2005, 03:06 Category: Benchmarks Views: 3168 Comments
Tutorial quote: This article is written solely from the frustration that I could not get a clear picture on what the G5 and Mac OS X are capable of. So, be warned; this is not an all-round review. It is definitely the worst buyer’s guide that you can imagine. This article cares about speed, performance, and nothing else! No comments on how well designed the internals are, no elaborate discussions about user friendliness, out-of-the-box experience and other subjective subjects. But we think that you should have a decent insight to where the G5/Mac OS X combination positions itself when compared to the Intel & AMD world at the end of this article.

How To Automate Spamcop Submissions

Post date: May 26, 2006, 07:05 Category: Network Views: 3059 Comments
Tutorial quote: Spamcop is a service which provides RBLs for mailservers in order to reject incoming mail from spammers.

Their philosophy is to process possible spam complaints from users. When they receive a certain amount of complaints during a time-period then they will blacklist the offender. This system is dependant on spam reporting from users. However, their submission process is not very user-friendly.

As I have said above, Spamcop is pretty much dependant on the user input. If no one submits and verifies spam, then they will have no blacklist. However that whole submission and verification process is a bit annoying. Why should I bother to actually submit spam to spamcop and have it verified? If I just delete it, that will take less time...

The human being isn't really made to do repeating things. This gets quickly boring and hence my idea to automate this submission and verfication process.
In this howto I will show you how I achieved that. All I do is just putting the spam into certain folders and our good old friend cron does the rest.

CGI Programming on the World Wide Web

Post date: December 12, 2005, 17:12 Category: Programming Views: 3022 Comments
Tutorial quote: The Common Gateway Interface (CGI) emerged as the first way to present dynamically generated information on the World Wide Web. CGI allows the computer to generate Web pages instantly at the user's request rather than being written by someone in advance. And at the time of this writing, it remains the only stable and well-understood method for creating such pages. Java presents problems that have not yet been solved. Other products are currently just in the announcement stage.

CGI is fun. You can get a kick out of writing scripts that perform tricks for you, and the users enjoy the spice the scripts add to your Web pages. But CGI has a serious side too: It lets the Internet offer the kind of interactive, user-driven applications that modern computer users have come to expect. CGI opens up an entire class of modern applications to the Web.

Creating a safe directory with PAM and Encfs

Post date: June 7, 2006, 20:06 Category: Security Views: 3181 Comments
Tutorial quote: Now, in my network (and others) the credentials provided at login could (and should) be used by those programs. How can you retrieve these credentials, providing enough security?
With a the PAM modules pam_script it's possible to store the password in a file, which will be used by fusemb and mount.cifs to read the password from.

To achieve security, one could make the user logging in owner and deny read/write for anybody else. Remove this file when the user ends his/her session.
This is enough, for runtime. But I was wondering, but what if the system crashes, and the file with the credentials remains on the harddrive? Anybody who is able to mount this harddrive with for example a lifecd, can read this file!

That's why I was looking for a way to encrypt this file.

With encfs this is very possible! At run time it gives an interface to encrypted files and directories, which does only exist at runtime! When the system is not running, there are only encrypted files, useless when you do not know the key to it. And this key is exactly the (encrypted) password! That's why I've chosen for a combination of PAM and Encfs.
