Linux.com :: sudo, or not sudo: that is the question |
|
Written by bibe
|
|
Sunday, 24 February 2008 |
If you've dabbled even a little bit with security matters, you know that giving root rights or the root password to a common user is a bad idea. But what do you do if a user has a valid need to do something that absolutely requires root rights? The answer is simple: use sudo to grant the user the needed permissions without letting him have the root password, and limit access to a minimum.

Linux.com :: Using MySQL as a filesystem |
|
Written by bibe
|
|
Sunday, 24 February 2008 |
With MySQLfs you can store a filesystem inside a MySQL relational database. MySQLfs breaks up the byte content of files that you store in its filesystem into tuples in the database, which allows you to store large files in the filesystem without requiring the database to support extremely large BLOB fields. With MySQLfs you can throw a filesystem into a MySQL database and take advantage of whatever database backup, clustering, and replication setup you have to protect your MySQLfs filesystem.

Debian package of the day :: rkhunter and chkrootkit: wise crackers only |
|
Written by bibe
|
|
Sunday, 24 February 2008 |
Rkhunter and chkrootkit are tools to check for signs of a rootkit. They will inspect the system they’re running on and report anomalies either through the shell or via email.
Although an attacker able to install a rootkit is likely also able to easily escape or delete these tools, not every attacker is a skilful one. Not every script kiddie knows about these tools or the way to cover its tracks. Since every single error can make the difference, on either sides, an effortless passive protection can do no harm and adds one more (maybe thin) layer of security.
Both rkhunter and chkrootkit, indeed, can be deployed quickly and require little management effort.

ComputerWorld :: The 5 users you meet in hell (and one you'll find in heaven) |

Written by bibe

Monday, 17 December 2007 |
Ah, end users. We sure do love them. Why, most of us wouldn't have jobs without them. But that doesn't mean users don't drive IT crazy sometimes, or maybe most of the time.
Just as a zookeeper cares for his monkeys one way and his rhinos another (we kid -- sort of), so too should IT tailor its responses to fit the individual styles of its end users, support managers say.

ossPro :: Linux: Create your own Domain Name Server (DNS) |
|
Written by bibe
|
|
Monday, 17 December 2007 |
One vital step to hosting your own domain is to set up a domain name server. One nice solution is to use Linux and the Berkeley Internet Name Domain(BIND) software. The primary job of a domain name server is to allow you and your users to associate your domains and subdomains with IP addresses. Oddly enough, even though the software is called BIND the daemon that you run is called named.

Behind the times :: Smartcard authentication on Linux and Mac |
|
Written by bibe
|
|
Monday, 17 December 2007 |
For various reasons, I need to secure access to some resources using two-factor authentication, and thus have been looking at smartcards. These little devices store digital keys and certificates, protected by a passphrase, and calculate digital signatures on-device. Hence the two factors: possession of the card, and knowledge of the password.
This sort of scheme is widely used by government agencies and large corporations (and largely reliant on Windows, too), but I wanted to find the low cost way in for the small operator using open source.

Mad Penguin :: Skype 2.0 vs. Ekiga for Linux |
|
Written by bibe
|
|
Monday, 17 December 2007 |
Many of us wonder, why is there so much excitement over Skype when, at its core, Ekiga is a more robust application with even more maturity behind it? The answer to that is rather simple - provide a compelling reason to use something besides Skype. Honestly, I believe Ekiga blows Skype out of the water with mature features (video calls) and it's open source heritage, which means that nothing 'weird' is going on without you knowing about it. Yet many Linux users by the truckload will still migrate over to Skype because they 'know' about this application from other platforms.

Linux.com :: CLI Magic: No-nonsense network monitoring tools |

Written by bibe

Monday, 17 December 2007 |
Linux is an excellent platform for network administration. If you want to monitor your network traffic, you can find many tools -- some accessible from a Web interface, others using a graphical interface -- but nothing beats the speed of the command line. Command-line tools are also useful in shell scripts, where they can help you perform complex tasks. Here's a handful of my favorites for monitoring network traffic.
