Install. Boot. Lpi. Server. Intrusion Detection with Tripwire LG #106. By Barry O'Donovan 1. Introduction A little over two years ago I was hacked. Someone broke into a web server I was administrating that had only Apache and OpenSSH running publically, and all packages were up-to-date. Tripwire is a file integrity checker for UNIX/Linux based operating systems and works as an excellent intrusion detection system. The idea behind Tripwire is quite simple: it first creates a "baseline" database of the state of the files and directories on your system and then on subsequent runs it compares the current state of the files and directories against this baseline identifying any deletions, additions or changes. In this article I will guide you through the process of getting and installing Tripwire, configuring it and setting it up to run on a daily basis. 2.
The easiest method of installing Tripwire is to use a vendor supplied package (I have checked and these are available for RedHat/Fedora Core, SuSE, Mandrakesoft and Debian). 3. EMAILREPORTLEVEL and REPORTLEVEL. Fix a Frozen System with the Magic SysRq Keys. You finally got your Linux environment to crash. Ctrl+Alt+Backspace does nothing, nor do the F-keys. You know you shouldn't have installed that bad driver, but you did it anyway. So you reach for the power button. Stop. Mashing in the power button to reboot could cause a problem if your hard drive is still being written to, and usually causes more problems than it solves. The Linux kernel includes a secret method of restarting your PC should it ever stop doing its job. Hold down the Alt and SysRq (Print Screen) keys. Here it is again: REISUB.
As an aside, don't try this if you just want to reboot. Jacob Peddicord - Jacob is a web developer, student, and programmer from Ohio.

I would lose a lot of time if I manually managed my configuration. In this tip I will tell you how to: Build up a feasible Vim configuration structure so your vimrc, plugins, syntax files, ... are all manageable. Putting your whole configuration in a version control system.
How you can access my (amazing) Vim configuration. Notice: When I write ~/ it means C:Documents and SettingsYourUser on Windows. Building a configuration structure I hope you know what a vimrc file is, if you don't read about it here. My current vimrc looks like this: fun! What, 4 lines? MySys: What O/S are we on?
Why is this smart? Runtimepath Runtimepath is really smart. ~/vim_local/plugin/ - All your plugins ~/vim_local/colors/ - All your color schemes ~/vim_local/doc/ - All your docs etc...

Manishrjain - flickrfs. Index About Flickrfs is a virtual filesystem which mounts on your linux machine like any other partition. Once mounted, it retrieves information about your photos hosted on your flickr account, and shows them as files.
You can now easily copy photos from your local machine to this mount, and it will automatically upload them to your flickr account. Similary, you can copy the files from your mount to your local machine, and it will download your images from flickr. All the files in the mount have a meta file attached to them, which provides access to title, description, tags, and license information. Modifying any of these fields and saving the meta file, will update them on the server as well. You can easily specify what is the default resolution of photos that you wish to upload, and the fs will automatically resize (read downsize) the photo, and upload it. That's not all, the latest verion of flickrfs, provides a syncing mechanism. Structure Flickrfs Home Directory $HOME/.flickrfs: /sets 1.
Creating Your Own Custom Ubuntu 7.10 Or Linux Mint 4.0 Live-CD W. Version 1.0 Author: Falko Timme <ft [at] falkotimme [dot] com> Last edited 11/28/2007 This guide shows how you can create a Live-CD from your Ubuntu Gutsy Gibbon or Linux Mint 4.0 system with a tool called remastersys. Remastersys is available in the Linux Mint romeo repository. You can customize your Ubuntu/Linux Mint system and then let remastersys create an iso image of it which you can then burn onto a CD/DVD. I do not issue any guarantee that this will work for you! 1 Installing Remastersys Open a terminal and become root: sudo su Then add the Linux Mint romeo repository to /etc/apt/sources.list and update the package database: echo "deb romeo/" >>/etc/apt/sources.list apt-get update Afterwards you can install remastersys like this: apt-get install remastersys Then leave the root shell so that you are logged in as your normal user again: exit 2 Remastersys Usage In order to learn how you can use remastersys, run sudo remastersys Examples: 4 Cleaning Up 5 Links.
Dia a drawing program. Welcome to Dia's new homepage. Dia is a GTK+ based diagram creation program for GNU/Linux, MacOS X, Unix, and Windows, and is released under the GPL license. Dia is roughly inspired by the commercial Windows program 'Visio,' though more geared towards informal diagrams for casual use. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It can load and save diagrams to a custom XML format (gzipped by default, to save space), can export diagrams to a number of formats, including EPS, SVG, XFIG, WMF and PNG, and can print diagrams (including ones that span multiple pages).
Download Dia and try using it; tell us what you think of it (visit the Contact page), including to report bugs if you find them. CategoryProject.
