Screen: an introduction and beginner's tutorial

Post date: April 15, 2005, 23:04 Category: Software Views: 2531 Comments
Tutorial quote: Most modern Unix-based operating systems (e.g. Linux, MacOS X, and BSD) come with a little console-mode utility called GNU Screen. It's a powerful tool in the hands of the console warrior, a veritable Swiss Army knife of text-mode human-computer interaction.

This utility, despite its considerable usefulness, goes unused by a great many people. Why is this? Few people even know it's there, and those that do rarely understand the problem it solves. In this article, I will explain what screen does for you, and provide a simple set of instructions for accomplishing basic tasks using screen. My audience is those that are skilled with the command line but who have little or no experience with screen itself.

Using FreeBSD's ACLs

Post date: September 29, 2005, 17:09 Category: Security Views: 3458 Comments
Tutorial quote: Five years ago (gee, has it really been that long?), I wrote a series of articles on understanding Unix permissions. Since then, FreeBSD has implemented something known as ACLs (Access Control Lists).

ACLs came to BSD as part of the TrustedBSD project. As the name suggests, they give a user finer access control over permissions.

Grub From the Ground Up

Post date: April 12, 2005, 17:04 Category: Software Views: 2708 Comments
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.

How To Run Fully-Virtualized Guests (HVM) With Xen 3.2 On Debian Lenny (x86_64)

Post date: March 8, 2009, 13:03 Category: Installing Views: 3918 Comments
Tutorial quote: This guide explains how you can set up fully-virtualized guests (HVM) with Xen 3.2 on a Debian Lenny x86_64 host system. HVM stands for HardwareVirtualMachine; to set up such guests, you need a CPU that supports hardware virtualization (Intel VT or AMD-V). Hardware virtualization allows you to install unmodified guest systems (in contrast to paravirtualization where the guest kernel needs to be modified); that way you cannot only virtualize OpenSource operating systems like Linux and BSD, but also closed-source operating systems like Windows where you cannot modify the kernel.

Learn REXX fast

Post date: September 1, 2005, 01:09 Category: Programming Views: 3239 Comments
Tutorial quote: If you’ve programmed under IBM operating systems, you’ve undoubtedly heard of Rexx. Rexx is the scripting and command language IBM bundles with all its mainframe, mid-range, and lower-end operating systems. What you might not be aware of is that Rexx also runs on almost every other operating system in the known universe. You can download Rexx free for all versions of Windows®, Linux, UNIX®, BSD, Mac OS, and DOS, and many other systems. It even runs on the three major operating systems for handheld devices: Windows CE, Palm OS, and Symbian/EPOC32.

What this means is, if you learn Rexx, you’ll know a scripting language that runs everywhere from mainframes to handhelds—and everything in between. Rexx is a general-purpose language that's powerful enough for mainframes yet flexible enough for other platforms. Best of all, Rexx is easy to learn.

Linux stateful firewall design

Post date: April 12, 2005, 17:04 Category: Network Views: 2400 Comments
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.
