Linux Keep an Eye on Your Linux Systems with Netstat
Post date: April 12, 2005, 12:04 Category: Network Views: 755 Comments: 0
Tutorial quote: Two of the fundamental aspects of Linux system security and troubleshooting are knowing what services are running, and what connections and services are available. We're all familiar with ps for viewing active services. netstat goes a couple of steps further, and displays all available connections, services, and their status.
Linux Setting the Clock on Linux
Post date: April 12, 2005, 12:04 Category: System Views: 642 Comments: 0
Tutorial quote: There are 3 protocols dealing with time: NTP (port 123), Time (port 37), and Daytime (port 13). If you're connecting to the Internet periodically, then synchronizing your clock when you dial up or from crontab is good enough. This applies also to most Linux machines at home or at work, even if they are connected all the time. Here is a short tutorial on how to set your clock using these 3 protocols.

Linux Linux stateful firewall design
Post date: April 12, 2005, 12:04 Category: Network Views: 785 Comments: 0
Tutorial quote: This tutorial shows you how to use netfilter to set up a powerful Linux stateful firewall. All you need is an existing Linux system that's currently using a Linux 2.4.x or 2.6.x kernel. A laptop, workstation, router or server with at a Linux 2.4.x or 2.6.x kernel will do. You should be reasonably familiar with standard network terminology like IP addresses, source and destination port numbers, TCP, UDP and ICMP, etc. By the end of the tutorial, you'll understand how Linux stateful firewalls are put together and you'll have several example configurations to use in your own projects.
Linux Grub From the Ground Up
Post date: April 12, 2005, 12:04 Category: Software Views: 931 Comments: 0
Tutorial quote: Grub is a world-class boot loader with insufficient documentation. In many ways it blows the doors of LILO. For instance, it's MUCH easier to use Knoppix to rebuild a grub boot loader than to rebuild a LILO boot loader. However, until you're comfortable with grub, it might seem just the opposite. All too often grub dumps you at a grub> prompt with no hint of what you should do. You might have heard that a successful reboot is just three commands away, but which commands? The state of grub's documentation is such that you can't figure it out unless you already know grub.

That catch 22 is the very purpose of this document. This document will to give you enough grub expertise that you can create a grub boot floppy on a working machine with grub installed (not necessarily as the bootloader, just installed), and use that floppy to bust back into a Linux machine with a blown bootloader, and then use that floppy to actually install grub as the bootloader.

This document does not discuss using grub to boot or dual boot Windows, mach, BSD, or other non-Linux operating systems. I might write on that subject later. But in the meantime, once you're familiar with the principles and practices of grub, given some study of existing documentation you'll probably be able to use grub to boot non-Linux operating systems.
Linux Introduction to Linux files
Post date: April 12, 2005, 11:04 Category: Miscellaneous Views: 820 Comments: 0
Tutorial quote: This newbie-level Linux tutorial is an introduction to handling files from the Linux command line. It will cover finding files, determining their type, renaming, copying, examining their attributes, reading their contents, and, in the case of binary files, how to get clues to learn something more about them. Further reading will be suggested for editing files since that topic is beyond the scope of this article.
Linux Migrate your Linux Web site to another hosting company

Tutorial quote: The Web site hosting business has become more competitive in recent years. If you can find a better hosting deal, you may be able to save money by switching hosting providers. But what's the best way to move your Web site? What if you have a virtual private server (VPS) hosting several domains? What about PHP and your SQL data? The thought of moving may be daunting, but moving servers is not difficult if you plan properly. Here's how.
