LyX 1.6 is ready for release

This month saw the release of LyX 1.6 release candidate 1. Occupying a position somewhere between a word processor and a mark-up editor, LyX is designed to meet the needs of professional and academic writers by allowing them to focus on their content rather than formatting and layout. It achieves this by eschewing some of the WYSIWYG conventions of a word processor.

Preventing Brute Force Attacks With Fail2ban On Fedora 9


Version 1.0

Author: Falko Timme <ft [at] falkotimme [dot] com>

Last edited 08/08/2008


In this article I will show how to install and configure fail2ban on a Fedora 9 system. Fail2ban is a tool that observes login attempts to various services, e.g. SSH, FTP, SMTP, Apache, etc., and if it finds failed login attempts again and again from the same IP address or host, fail2ban stops further login attempts from that IP address/host by blocking it with an iptables firewall rule.

Interview: Andy Hertzfeld

Quite often, Steve Jobs is given all the credit for the original Macintosh - but in reality, it wasn't Steve Jobs who made the largest contribution to the project; in fact, he didn't even come up with the idea. Jef Raskin envisioned an easy-to-use computer with a graphical user interface, and somewhere in 1979 he got the green light to start the Macintosh project, and together with Bill Atkinson he put together a team to develop the hard and software. It wasn't until much later that the project caught Steve Jobs' eye, who realised the Macintosh project had more potential than his own brainchild, the Lisa. One of the people on the Macintosh team was Andy Hertzfeld, and O'Reilly News interviewed him a few days ago...

Make etexts pretty with GutenMark

Project Gutenberg, the online library of more than 25,000 free books, is a treasure trove for bookworms and casual readers alike, but turning electronic text files into a readable form is not as easy as it may seem. In theory, since etexts are just plain text files, you should be able to open and read them on any platform without any tweaking. In practice, however, this approach rarely works. Hard line breaks, for example, may ruin the text flow, making it virtually impossible to read the book on a mobile device. Another problem is that most books are stored as single files, so locating a particular chapter or section in a lengthy book can be a serious nuisance. Then there are minor but annoying formatting quirks, such as inconsistent handling of italicized text, use of straight quotes instead of smart ones, and so on.

Be a Productive Linux User


Use Terminator: Terminator is a nice way to free your valuable screen space from multiple terminal windows. Instead of using one terminal window for each task, divide an existing window horizontally or vertically each time you need a new terminal window. So if you find yourself using 8 terminal windows, you can use Terminator and pack your terminals into 2 windows.



Set Terminal as Desktop Background: Some time ago, I showed you how to setup your terminal as a desktop background. This is a great way to assign certain portion of your desktop background for terminal window which can be seamless and be part of your desktop wallpaper. Two popular way to achieve this is with the use of Tilda or Devilspie. It would be even better if we could setup Terminator with Devilspie; I will have to find out and get back to you on that.




Use Conky: Conky can be used to have system stats, live, right on the desktop. Apart from giving you OS stats, conky can be setup as a music player and can alert you when you receive e-mail with IMAP and POP3 support. Conky has similarities with devilspie in the sense that it also integrates itself with the desktop background, without having a separate window for itself.



Use Pidgin: I am still surprised to see people using separate IM clients for chatting. Pidgin is a multi-protocol Instant Messaging client, which is a great way to stay connected with your friends regardless of the IM service they use. If you are a console junkie you can use the console version of pidgin, known as Finch.



Gnome-do: This will set your productivity on fire. Gnome Do wiki has an excellent description of what can be done with this wonderful application, so I will quote them:


“GNOME Do (Do) is an intelligent launcher tool that makes performing common tasks on your computer simple and efficient. Do not only allows you to search for items in your desktop environment (e.g. applications, contacts, bookmarks, files, music), it also allows you to specify actions to perform on search results (e.g. run, open, email, chat, play). Want to send an email to mom? Simply type “email mom.” Want to listen to some music? Simply type “play beatles.” Do provides instantaneous, action-oriented desktop search results that adapt to reflect your habits and preferences. For example, if you use Firefox web browser often, typing “f” in Do will launch it. Or, if you visit The New York Times webpage often, Do will open it if you simply type “nyt.” Unlike other search tools that present search results as flat, homogeneous lists, Do provides familiar graphical depictions of search results that assure you that your intent is being realized correctly; searching for “mom” will show a picture of mom, and searching for “beatles” will show a Beatles album cover. Do has many more powerful and exciting capabilities that must be seen to be appreciated.”



Do you know any other linux application that will help you be a more productive linux user? Do share them on comments.

Easy file uploads with Droopy

Suppose someone wants to send you a large file. They could try to send it via email, but many email servers impose limits on file size. They could try sending it over during an instant messenger or Internet Relay Chat session, but that's slow, as the file actually gets transferred twice: once to the chat server, then to your machine. File transfer services like RapidShare and MegaUpload are fine, but not for confidential information. Of course, you could set up an FTP server on your box, but you don't want to leave that door open all the time. Luckily, there's now an easy solution: droopy.

Tailf - watch the linux log file grows

Another overused linux command that has been quite around from this linux blog entry and widely used command on monitoring log file tail. Tail binary allows a user to watche the growth of a log file. Watching the log file grows can be done using an additional -f parameter. Alternatively, another approach to watch a log file grows can be done using tailf binary command.

To tailf or to tail -f ? That is the question.

Tailf binary is part of util-linux-ng linux package while tail binary is part of coreutils linux package.

File size difference of tailf and tail binary command:

# ls -la /usr/bin/tailf /usr/bin/tail

-rwxr-xr-x 1 root root 7416 2007-10-16 21:48 /usr/bin/tailf
-rwxr-xr-x 1 root root 43576 2007-10-30 17:52 /usr/bin/tail

Man Tailf
Tailf will print out the last 10 lines of a file and then wait for the file to grow. It is similar to tail -f but does not access the file when it is not growing. This has the side effect of not updating the access time for the file, so a filesystem flush does not occur periodically when no log activity is happening. Tailf requires only a single parameter when watching a growing log file. Tailf follows the following command format

# tailf logfile

Tailf is extremely useful for monitoring log files on a laptop when logging is infrequent and the user desires that the hard disk spin down to conserve battery life.

Tailf Usage Examples

# tailf /var/log/messages
# tailf /var/log/maillog

Linux under attack: Compromised SSH keys lead to rootkit

The U.S. Computer Emergency Readiness Team (CERT) has issued a warning for what it calls “active attacks” against Linux-based computing infrastructures using compromised SSH keys.

The attack appears to initially use stolen SSH keys to gain access to a system, and then uses local kernel exploits to gain root access. Once root access has been obtained, a rootkit known as “phalanx2? is installed, US-CERT said in a note on its current activity site.

PostPath: Enterprise-strength open source alternative for Exchange

For enterprise system administrators looking for interoperability with Microsoft Exchange, but not the high costs associated with it, PostPath email and collaboration server could be a smart business investment. Boasting interoperability with Exchange environments for a third of the cost, thanks to its use of the Postfix mail server and many other open source components, PostPath provides drop-in capability and compatibility with Exchange environments without the need for making changes to Outlook on the client side. Being compatible with Exchange means that it can be managed using Microsoft's Active Directory infrastructure. The latest version, PostPath v3.1.2, adds support for Blackberry Enterprise Server and ActiveSync, allowing you to use mobile devices to access your email.

RDesktop - remote desktop howto

We can never remove the fact that some companies still use any other desktop operating systems from their network. Several reasons for these are due to commercial and propriety softwares and customized applications that currently being managed and needed by certain specific company departments, whether those clients are located remotely or just a single department hop, providing support with these clients is never been at rest.

Here's a document entry on managing and connecting to Windows (TM) based operating systems (Windows 2000/2003, XP Terminal servers, Windows NT) from Linux box using a remote desktop tool called RDesktop.

rdesktop is an open source client for Windows NT Terminal Server and Windows 2000/2003 Terminal Services, capable of natively speaking Remote Desktop Protocol (RDP) in order to present the user's NT desktop. Unlike Citrix ICA, no server extensions are required.

rdesktop currently runs on most UNIX based platforms with the X Window System, and other ports should be fairly straightforward.

rdesktop was initially written by Matthew Chapman based on various scarce documentation, wire sniffs, and trial-and-error. It is released under the GNU Public Licence (GPL). Please send feedback, bug reports and patches to the appropriate mailing list. Patches can also be submitted to the SF patch tracker.

This X client for remote desktop to windows machine makes use of RDP on establishing protocol with Windows OS machines. Rdesktop connects to remote machines extremely fast compared to other remote desktop tools. By default, rdesktop establishes TCP/UDP connection to host's port 4899. Extreme works have been done to make Rdesktop to cover a lot of nice features that would be very usable with remote connection to window-based client machines.

RDESKTOP INSTALLATION
=====================

# yum -y install rdesktop

BINARY LAUNCH:

Ctrl+F2, rdesktop

RDESKTOP USAGE
==============

# rdesktop windows-machine-host
# rdesktop 123.123.123.123


The command issued above attempts to connect to a windows machine with an IP address of 123.123.123.123 . If no firewall exists between the connecting host, and the client, a successful rdesktop connection would be established immediately prompting rdesktop machine for username and password details.

If you wish to connect with supplied username and password using rdesktop

# rdesktop 123.123.123.123 -u username -p password

The above command connects remotely to windows XP machine and supply the needed username and password. This command does not work by default to Windows 2000 terminal machines as the default auto login configuration from Windows 2000 needs further tweaking. This tweaking method would not be discussed here. However, the command above works out right with Windows 2003 terminal server machines.

Rdesktop also features domain authentication during the remote connection attempt. The authentication attempt queries domain servers for centralized user authentication. This can be possible using rdesktop parameters.

# rdesktop 123.123.123.123 -d domain.com

Screen geometry can also be specified before remote connection is being made. Here's a sample example of using rdesktop geometry parameter

# rdesktop 123.123.123.123 -g 80%

which uses 80% of client screen to be displayed from connecting host.

Data transfer between the two host using rdesktop can also be encrypted by passing toggle rdesktop parameter like do

# rdesktop -E 123.123.123.123

For data compression during rdesktop data transfer can be done like so

# rdesktop -z 123.123.123.123

Audio sounds from rdesktop server can also be redirected to rdesktop machines. This can be handy if you would like to have livestream audio sounds and dumps it live to rdesktop client machines, which can be done like so

# rdesktop -r sound:remote 123.123.123.123

Alternatively, audio sound from client can be heard from rdesktop server by toggling the remote audio parameter like so

# rdesktop -r sound:local 123.123.123.123

Remote desktop protocol version can also be specified manually to rdesktop connection using the followinf rdesktop parameters

~~~~~~~~~~~~~~~~~~~~~~~~~~~
-4 uses RDP version 4
-5 uses RDP version 5
~~~~~~~~~~~~~~~~~~~~~~~~~~~


Remote client's disk, device, COM ports, LPT ports, printer details can also be specified from rdesktop command.

Using rdesktop, here is my captured simulataneous rdesktop screenshots with two remote machines Windows XP and Windows 2000 from Fedora 7 desktop:


Rdesktop Summary
===========

Thomas Vander Stichele: Angel

There’s a guy in Barcelona who runs an antique store. Well, maybe it’s not an antique store, because it doesn’t like like stuff my mom would actually buy. And I’m not even sure if he’s selling.


But he cooks for anyone who comes in, whatever is available, and turns it into honest and magical meals. He’s probably Barcelona’s best kept secret - he’s not in any guide (which is a good thing), and I doubt he even has a license to do what he does.


He gives you whatever he has, and what he has is always excellent quality. He probably goes by the farmers and vineyards himself to select his products. No is not a word he accepts, and there’s no way you can eat everything he gives you.


I’m always a bit worried when I bring people there because it takes some time to get there, it’s always difficult to organize it, and you just never know how people will react, or how Angel will react if he happens to be in a less sociable mood and gets asked to cook something non-meaty for example. But I’ve just never been disappointed, so I don’t know why I worry.


Today we went there to kick off our developer meeting now that everyone’s back from holidays and Julien, a new guy, just started. We got chorizo, manchego cheese, beans, a huge tortilla, a special Cabrales cheese which was very strong but good, bread, and duck pate. And those were just the starters, I had to explain to my surprised collagues. After that, we got blood sausage, cutlets, and hake. All of this with some wine, and desert and coffee at the end.


And when you get up and leave, you ask him for the price, and he makes one up on the spot for the whole group. Rumour has it it’s cheaper if you’re a girl and can part with some pecks on the cheek.


If you ever get to Barcelona, drop me a line for the address. And let me know if you write for a tour guide or travel magazine, so I can give you the wrong information. I don’t ever want to see it get ruined.

Christian Schaller: GUADEC photos online

I have been looking for a new hosting option for a while and last week I finally choose one. Based on recommendations from others I ended up going with Slicehost. Slicehost advertise themselves as being a hosting company for developers, which I learned is definitely true. It is the first time ever I had a hosting setup where I even needed to install and configure my own email server. Learned a lot about Postfix over the last weekend )


That said their setup is pretty nice. You can choose which linux distro you prefer from a quite big list and they will automatically set up your slice with that distro for you. They also have nice webtools for configuring things like DNS. And finally they got a lot of easy to follow tutorials on how to get common server tasks configured and running. Most of them Ubuntu centric, but I found it easy enough to find the Fedora equivalents when needed.


Once the basics was taken care of it was time for me to get my photo gallery back online after a longer period of being offline. Mostly due to me not having kept the gallery code up-to-date (and thus secure) it had been disabled at my old hosting provider. So upgrading to latest version was step one. The upgrade instructions turned out to not work at all, but doing a fresh install seemed to do the upgrade job just as well, it still managed to pick up all my old photos. I am still using Gallery 1.x though, but I noticed that Fedora packages Gallery 2. So I should probably switch to that at some point as having Fedora packagers make sure I am up to date without glaring security holes is more likely to work in the long run.


Anyway, to summarize a long story, my photos from GUADEC are now online )


I also orderd myself an Epson 350 photo scanner today after discovering that <a href=”http://avasys.jp/hp/menu000000500/hpg000000442.htm”>Epson</a> actually provides official drivers for Linux. Hopefully I will soon also get all my pre-digital photos online.

Objectify: Overview

This is part of a series of articles from J. Scott Edwards about his pet project Objectify.

– Editor



History


Right after Y2K I decided to resurrect a project I had started in the late ’70s to write an operating system. I started a project called EasyOS (1) on SourceForge to develop an OS based upon the best parts of Linux, FreeBSD, OpenBSD, etc. After toying around for a while I decided that part of the problem was that current operating systems are basically the same as the operating systems I had worked with in the 1970s, with the addition of a GUI. One example would be that all data is stored in files.


I decided that instead of using the same paradigms as existing operating systems, I needed to rethink those paradigms. I started another project: New World OS on SourceForge and in December 2004, I wrote an article for OS News about some of my ideas.


When it came time to start developing the system, I debated whether I should start completely from scratch; develop it from the hardware interface level and work my way up, or if I should start by testing some of my ideas on an existing system. If I started on top of an existing system I could see if my ideas were feasible, before dumping years worth of time into them only to discover that I had overlooked some fundamental flaw. I decided it made the most sense to test out some ideas on top of another OS first. To do releases on SourceForge I needed a package name. New World OS didn’t seem like a good package name because it wasn’t really an OS yet. I decided to call the package Objectify because it stored everything as an object. I often think that I should have called it Insomnia because almost all of it was developed while I should have been sleeping.



I started out storing the objects in files, each object in a separate file, but that proved to be cumbersome. I then tried storing all of the objects in a “sparse” file. Oddly, that ended up consuming gobs of disk space. Since one of my main ideas was to store objects directly on the hard drive and NOT in files, I ultimately decided to “just do it” and started reading and writing objects directly to an entire hard drive (like /dev/hdb) or a disk partition (like /dev/hda7). This worked quite well on Linux, but hasn’t worked on other operating systems like FreeBSD and OpenBSD, so I added the capability to substitute a regular file (like ~/.private.obj) for the block device (2).


One of the fundamental ideas, if not THE fundamental idea, was to eliminate storing data in files. I wanted to store data in a format more natural to the computer, so that a program did not have to read and convert it’s data from a file, do its thing, and then convert the data back to a file. I wanted the program to store it’s data in objects and then, only if the data had to be exchanged with another device, convert it to a file.


While I was working on the project, I had a collection of documents that I was scanning into the computer so I could shred the paper copies. However, since my project was not going to be ready to store these documents for some time, and I did not want to have the files sitting around on my computer or on DVD-R without encryption, I realized I could create a generic “FILE” object that would just store the file data until it was ready. I began storing my important documents in this manner in 2006 and now have over 3,500 files stored.


In January of 2007 I decided it would be nicer if the Objectify package had it’s own project on SourceForge, so I created an Objectify project. However, I have not completed the move so the CVS repository and the released packages are still under the New World OS project. The only thing I have in the Objectify project so far are the Bug and Feature Request Trackers.


I find it ironic that my initial goal was to eliminate the storing of data in files but currently that is the most developed function of the project. However, it is interesting to note that Objectify is inverted from other systems; instead of storing objects in files, it stores files in objects.


 


Notes:


 



  1. In early 2005 someone else wanted to use the EasyOS moniker on SourceForge. Since I was concentrating on New World OS by that time, I let them take it over. So the EasyOS project that is now on SourceForge has no relation to my project.

  2. I have tested the code on FreeBSD, OpenBSD, and Cygwin. I have started trying to get it to compile on Mac OS X but there were a couple of POSIX functions that are missing on OS X and I haven’t had time to work through it.

Sauerbraten blends the best of FPSes like Quake and Max Payne to give you a unique gaming experience.

HowTo: Install FFMpeg on Fedora Linux

FFMpeg is a complete and free Internet live audio and video broadcasting solution for Linux/Unix. It also includes a digital VCR. FFMpeg can encode in real time in many formats including MPEG1 audio and video, MPEG4, h263, ac3, asf, avi, real, mjpeg, and flash.

FFmpeg can generate a lot of different types of multimedia files with a variety of audio and video codecs inside. Sometimes these formats do not adhere to "accepted" specifications. Many open source multimedia playback applications have been specifically tuned to play all manner of multimedia files, no matter how incomplete or broken. However, certain widespread, proprietary multimedia applications, such as Microsoft Windows Media Player and Apple's QuickTime Player, are a little more rigid in the types of files they will accept.

FFMPEG Fedora Installation

Fedora repo supports FFMpeg. To install, simply issue

# yum -y install ffmpeg

FFMPeg Usage

# ffmpeg -i inputfile.ext outfile.mov
# ffmpeg -i inputfile.ext outfile.mp4
# ffmpeg -i inputfile.ext outfile.mpg


To convert a movie file into a playable AVI file
# ffmpeg -i inputfile.ext -vcodec msmpeg4 -vtag MP43 -acodec mp3 outfile.avi

To use Microsoft MPEG-4v2 video
# ffmpeg -i inputfile.ext -vcodec msmpeg4v2 -acodec mp3 outfile.avi

To create MPEG file with MPEG-1 video and MP2 audio.
# ffmpeg -i inputfile.ext outfile.mpg

To convert FLV to MPG using ffmpeg
# ffmpeg -i inputfile.flv -ab 56 -ar 22050 -b 500 -s 320x240 outputfile.mpg

Yes, you can use MPEG to convert video files from one format to another format, with a different video quality and pass. File output from FFMpeg was also tested to work with Windows Media player, Apple Video Player, Quick Time players and more.

That is all folks.

The case for Java modularity

The case for Java modularity: The lack of an effective modular programming model has frustrated Java developers since the Java platform's infancy. Until recently no single solution had stuck. In this article, Jeff Hanson explains why modularity is a next evolutionary step for the Java platform. He then surveys the two JSRs that propose to bring modularity to Java 7 -- JSR 291: Dynamic Component Support for Java SE and JSR 277: Java Module System. Both would bring the programming model popularized by OSGi to the Java platform, but they differ -- sometimes greatly -- in execution and philosophy...
