But moving to a different operating system can be confusing, no matter how well-designed it is. Here's a list of tips that might save you some time while you're getting used to Ubuntu.

Splitting lighttpd Logs With vlogger And Creating Statistics With Webalizer

Post date: January 31, 2008, 13:01 Category: Miscellaneous Views: 3779 Comments
Tutorial quote: Vlogger is a little tool with which you can write lighttpd logs broken down by virtual hosts and days. With vlogger, we need to put just one accesslog.filename directive into our global lighttpd configuration, and it will write access logs for each virtual host and day. Therefore, you do not have to split lighttpd's overall access log into access logs for each virtual host each day, and you do not have to configure lighttpd to write one access log per virtual host (which could make you run out of file descriptors very fast). At the end of this tutorial I will show you how to use webalizer to create statistics from the lighttpd access logs.

Port Knocking

Post date: April 16, 2005, 10:04 Category: Network Views: 3418 Comments
Tutorial quote: Firewall administrators are challenged to balance flexibility and security when designing a comprehensive rule set. A firewall should provide protection against malfeasants, while allowing trusted users to connect. Unfortunately, it is not always possible to filter out the bad guys, because filtering on the basis of IP addresses and ports does not distinguish connecting users. Bad guys can and do come from trusted IP addresses. Open ports remain a necessary vulnerability: they allow connections to applications but also may turn into open doors for attack. This article presents a new security system, termed port knocking, in which trusted users manipulate firewall rules by transmitting information across closed ports.

Virtualization With VirtualBox 3.1.x On A Headless Fedora 12 Server

Post date: March 11, 2010, 13:03 Category: Installing Views: 2983 Comments
Tutorial quote: This guide explains how you can run virtual machines with Sun VirtualBox 3.1.x on a headless Fedora 12 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

Tripwire on your Fedora Box

Post date: April 16, 2005, 00:04 Category: Security Views: 5404 Comments
Tutorial quote: Tripwire is an Intrusion Detection System. This can be used to alert users whenever their system is compromised. Tripwire detects and reports changes in system files. It will alert you through email whenever a change is detected. If the change is due to normal system activity, you can instruct Tripwire not to report the change to that file in future. If the change is not due to normal system activity, then it is a clear indication that something is wrong and you need to act immediately and fix the issue. Thus tripwire comes very handy to maintain the integrity of the system.

There is lot of information on the web about Tripwire. Some people might argue that AIDE (Advanced Intrusion Detection Environment) is better than tripwire and so on. This comparison is beyond the scope of this article. This is an introductory article for novice users who are interested in installing Tripwire on their Fedora Box. Advanced users can refer to the web for relevant information or they can contact appropriate mailing lists like fedora users mailing list.
