In times of crisis, Linux may be the choice!

2012-01-24T21:59:00.003Z

According to this news digital diary (DD), the "Linux advances on Windows andUnix in the Enterprise '! Needless to say that I read this news with great satisfaction. As the crisis global installed, there are already many administrators who intend to migrate servers to free platforms, says the second study that formed the basis of news dd. I hope you do not remain the intention! In Portugal, despite the crisis hit, I think this market (open source) will not grow, because mostmanagement applications (billing, accounting, etc.) work on Microsoft platforms(client and server) and not simply its migration to Linux based systems. One day,perhaps, this paradigm shift, that is, the technology is all over the market! Have you thought about buying a computer solution for your company and only pay for the hardware, service and little more? Well no! And antivirus? You do not need!And antispyware? You do not need! And format the PC and need to insert a dateserial numbers that the client already lost? You do not need! And being forced tobuy the new new version of Windows and Office M. to keep up? You do not need!Of course, the Windows operating system also has its advantages, but when the discussion is cost containment, there is not much to say.

Welcome Gnome3 or not!

2012-01-09T21:31:00.005Z

Gnome3 started using when he left the CM17. Soon after its installation, the first impact was "uauuuu the Gnome3 is spectacular." After a few days, I started to miss some things in Gnome2, the list
of open programs on the taskbar, the list of the commands in the command execution manager (the ALT F2) that does not appear and to make matters worse you can not execute the command SMB: / / this manager (the ALT F2), the widgets that have been abolished, among other things! I searched the Internet and noticed that there are already many users turn to the desktop XFCE, since with some changes, is very close to the Gnome2! Still, I insist and keep the Gnome3 at least until I reach the limit of patience! In my opinion the Gnome project wanted, and well, a new experience to innovate in the workplace. Despite some shortcomings, I think the project is following the natural evolution and the future work environment will be a renewed, modern and user friendly. Apparently, Mr. Linus Torvald also walks with Gnome3 clueless! It seems that Google Dave Jones, Linus also complained about the new interface of Gnome. If you want to read here.

Not Grep!

2011-12-26T22:46:00.005Z

It gave me a way to list several times using the grep command to the contrary, this is to list the contents of a file that contains less lines given string. For it is only necessary the-v parameter as shown below:
# cat file.txt | grep-v "exclude".

Mikogo - a great alternative to TeamViewer!

2011-12-09T12:42:00.003Z

Teamviewer know? Well, I present you, if you do not know, Mikogo, which I think is an excellent alternative.

This tool can be used in various areas: domestic, academic and even professional use. Some of the features available are:

     virtual meetings
     Web Conferences
     Product Demos
     web presentations

VPN: Importing files with. PCF

2011-09-15T20:37:00.000+01:00

If you want to import a file with. PCF to create a Cisco VPN compatible with (VPNC), need to install the network-manager-vpnc. This distro to Debian, or derivatives, such as the Magic Box that I myself am using.

This applies also in case they want to create a Cisco VPN connection from scratch.

Caixa Mágica

2011-08-31T00:17:00.004+01:00

Since I'm a fan of Debian, I could not test the new version of the Magic Box (CM16) based on this operating system (OS). There are about 2 months installed it on my desktop PC today and installed it on my laptop.
First impressions is that I have a full OS with office tool LibreOffice 3.3, EXT4 file system, Firefox 4.0, Shotwell Photo Manager, Banshee Music Player and automatic detection of proprietary drivers.
For instant messaging (IM) is built Empathy surprised me this new version the interface simple and friendly and the ability to connect to multiple IM systems. With Gwibber diffusion can add accounts like Twitter, Facebook and identi.ca, providing a common tool to interact with these social networks.
The Magic Box Software Center is very well played as a tool for package management. It is organized by categories and still have a dynamic part of recommendations.

What can I say more?! Try it and you will see will like it.

Video Editing on Linux - See OpenShot Editor

2011-07-05T20:41:00.004+01:00

Just recently I needed to edit videos and I'm a layman in this field had some difficulties.Among various tools I tried, the simplest and quickest way to learn was the OpenShot.
The installation of this tool for Debian distributions can be done through Synaptic it is in the repositories. If you prefer to install "a la pata" is as follows: sudo apt-get installOpenShot.
The features available are not many, but for many users (like me) arrives perfectly.

features:
Cut pieces of the video;
Add tags in the video;
Multiple bands;
effects;
transitions;
Import video, images and sounds;
Undo changes;
Export to various video formats;

How to put a video on a track:
(1) Click on the icon + (plus) and choose the video;
(2) Move the video imported onto the track at the outset;
(3) can add other video, pictures and even music files / sounds;

How to cut pieces of video:
(1) pick-and functionality divide and clicking with the mouse at the beginning and end of the piece to remove;
(2) Clicking the right mouse button over the video piece and remove;

Add a picture:
(1) Click on the icon + (plus) and choose the image;
(2) Move the image to the track where if you want to place;

Add effects and transitions:
(1) Just select the transition and move up the track to the site, where you want the transition;
(2) In effect, it is the same thing, but this is all in the band, or piece of track if it is divided;

Export:
Although you can export to many different formats, I will present the simplest and Iworked flawlessly.
(1) File -> Export Video -> Tab: Simple -> Profile: DVD -> Destination: DVD-NTSC ->Video Profile: DV-NTSC -> Quality: High -> Export.

Linux - Screen Resolution in Portable 10 "

2011-06-17T21:03:00.000+01:00

Today I had a problem installing Red Hat Enterprise Linux 16 (CM16) with a portable screen 10 "because the operating system can not detect the resolution and that it should use. The image was so poor he could not even read the text presented.

To overcome the problem follow these steps:

     I called a TFT monitor to the laptop and carried out the installation as usual;
     Once installed the CM16, I had to make the resolution setting the screen, manually in xorg.conf file:
         vi / etc/X11/xorg.conf (if no, it is created);
          Paste the following information:

                  Section "Device"

                  Identifier "Video Device Configured"

                  Driver "OpenChrome"

                  option "PanelSize" "1024x600"

                  option "ForcePanel"

                  EndSection

         Restart.

This problem happened to me on a laptop (type NetPC) brand Elonex Webbook. This solution resulted in CM16, but probably also work on Debian based distros (Ubuntu, etc).

Problems with Dropbox?!

2011-02-23T00:02:00.001Z

The subject today is again Dropbox. I've been just describing a problem I had with Debian 6.0 (squeeze) 64bit with this tool. The problem was that after the OS update,Dropbox longer boot!
To resolve, in my case resulted, can eliminate the Dropbox folder settings in your user,which should be / home /% user% /. dropbox.

rm-rf ~ /. .dropbox

After returning to run the Dropbox that will lead you to the setup wizard and here only have to look out at the stage where he can for you to choose the folder location"Dropbox. " If they choose the same location, is detected equal another folder, thenselect the option "Merge. "

They may know more about Dropbox here. or if they wish to install may do so by this hyperlink.

Configure a network interface with ifconfig

2011-01-03T19:47:00.000Z

May eventually need to configure a network interface in a very quick but not permanently.To do so can use the ifconfig command as follows:

ifconfig eth0 192.168.10.200 netmask 255.255.255.0

If you do not know what is the interface or if you want to check if the configuration iscorrect, they can simply run ifconfig.

After configuring the IP is to configure the gateway (gateway). In this case we will do isadd a route to route network packets to the gateway:

route add default gw 192.168.10.254

Today the Internet is a dangerous place for children! Leave a child alone in navigating the Internet is as dangerous as leaving a child alone in a very busy road traffic!Agree?!

Gnome Nanny is a project that lets you adjust when, where and how children can browse. This does not mean it is a check on the kids, like to think it is more a protection.

When - lets you adjust where you can surf heights;Where - to set / filter web pages that can refer;How - to adjust the duration that can surf the Internet;

Saving energy on Linux

2010-07-17T02:07:00.001+01:00

If you have a PC or a server passing of the time with no activity on the disk, can save a little on the electricity bill if the halt. It's true that can make configuring power management on your desktop environments (KDE, Gnome, etc.) but what I present here is a simple and rapid method for manually configuring this mechanism, ie the operating system Bash.
The tool to use hdparm is used to but to suspend the operation of hard disks can also adjust parameters of cache, DMA, or even acoustic noise, among others.
- Installation: aptitude install hdparm
- Suspend for 2 minutes: hdparm-S 24 /dev/ sda
- Check the condition of the disk: hdparm -C /dev/sda
- Configure the permanent suspension: vim /etc/hdparm.conf - And add at end of file the following code:
/dev/sda {
spindown_time = 24
}
- Then you just have to restart your PC, or the service - /etc/init.d/hdparm reload

Note: the sda is the disk ID in Linux, in your case is hard to see that they have, they can do it as fdisk-l and then with the tool Partition Editor (GParted). If you have only one SATA disk to start is sda if hda is an IDE. If they are not much inside it, then I suggest you to search or ask here on the blog:)

How to embed subtitles in Divx movies with Linux

2010-05-10T22:47:00.000+01:00

It is unfortunate that the Playstation 3 does have the ability to read DivX with external subtitles, or captions to a text file. It's a clear choice from Sony, but fortunately there is no alternative.
I come therefore have a short tutorial that despite being targeted at Linux operating systems, it also serves for those using Windows or MAC. The tool I'm talking about is native to Windows, so to run on Linux, you must have Wine installed.

Requirements for Linux OS:
- Subtitles of the film format. Srt;
- Wine installed.

Tutorial:
1 - Download AVIddXSubs.zip;
2 - Unzip the downloaded file;
3 - In the uncompressed folder, run the AVIAddXSubs.exe;
4 - Place the folder containing the movie in the box - c: \ pasta_do_filme (see figure). Or you may specify that they intend to embed the movie subtitles - c: \ pasta_do_filme \ filmecaseiro.avi | c: \ pasta_do_filme \ filmecaseiro.srt. The pipe symbol (| <- this one) makes the division between the way the movie and the file path of legends.

5 - This small tool consists of two tabs of settings. Then I leave you a picture of the tab "Settings 1" already with some modifications. It is up to each experiment to obtain the desired result.

6 - Probably the PS3 will have to select the subtitles when they start playing the movie, for these are inserted through the codec, and is not always visible.
7 - Finally, if you have questions whistle: P, I mean comment, I try to respond.

Concatenate split files of type 001, 002

2010-04-22T22:56:00.006+01:00

Today I leave you here a very simple way to concatenate files split, where normally the extension is 001, 002, 003, etc..

These files are very common in RapidShare or services of that kind.

My preferred way:
cat ficheiros_divididos.avi.??? > Ficheiro_concatenado.avi

In this second way that I present have to be careful not to have divided other files in the directory where:
cat *. [0-9] [0-9] [0-9]> ficheiro_concatenado.avi

find files by user identifier (user id - uid)

2010-03-09T20:50:00.000Z

If you have a file server to Linux, certainly have needed to find files of a particular user, or its UID or GID, or even by your username. Here is this article, some examples of how futilizar the find command for this and other effects more basic.

Find files by user identifier (UID)?
find. /-uid 502

For user name:
find. / user-joselito

For identifier then the group (GID):
find. /-gid 1000

Locate all files with extension. Doc:
find. /-iname "*. doc"
find. /-name "*. doc"

Find files that have changed in the last 24 hours:
find. /-name "*. doc"-mtime 0

Find files that have changed to 48:
find. /-name "*. doc"-mtime 1

Locate all files with permissions 777:
find. /-perm / 777

Find files that have changed to exactly 5 days:
find. /-mtime -7

Find files that have changed less than 5 days:
find. /-mtime 5

Find files that have changed to more than 5 days:
find. /-mtime +5

Note: The difference between the parameter name and iname is that the latter is case sensitive - distinguishes the case matching. The parameter. / Indicates that the search is performed from the directory where you are.

Edit PDF files with Sun PDF Import Extension

2010-02-16T19:37:00.002Z

Possibly ever needed to edit a PDF as a text document if it were! In Openoffice is an extension that makes this wonder possible - Sun PDF Import Extension.

Installation:
1 - Download the extension sun-pdfimport.oxt.
2 - Run
3 - Reboot Openoffice
4 - Open a PDF file like a text document.

The import can be time consuming, depending on the type and size of PDF, but believe that the result is really amazing. The PDF that I imported kept proper training of the document. In order to keep the original formatting, the Sun PDF Import, insert all the phrases in the text boxes that can be edited after the event.

Note
The Sun PDF Import Extension is independent of the operating system, but either way, the test results presented here were made in the version of OpenOffice 3.2, the operating system 5 64bit Debian.

Configure Intel PRO / Wireless 3945ABG in Debian

2010-02-04T23:25:00.001Z

This article serves to try to resolve some cases where they have problems in setting up wireless networks (RSF), with an Intel PRO / Wireless 3945ABG.
I think that whoever installed Debian in a more manual, ie the installation image Netinst, as was my case, you may have this problem. If you followed the article I published (see here) and have a FSR of this model, which surely must have had this problem.

Resolution:
Add the following repository to / etc / apt / sources.list, if you have not already:
deb http://ftp.de.debian.org/debian lenny main non-free

apt-get update
apt-get install firmware-iwlwifi

Restart the PC, and now you should see the card when RSF running ifconfig.
From here you just add the network through NetworkManager GUI application.

Some useful commands:
iwconfig - shows the interfaces of the active RSF.
ifconfig - Shows the configuration of network interfaces.
ifconfig wlan0 - Shows the interface configuration RSF wlan0.
ifconfig eth0 down - Disables the network interface eth0 wired

Dropbox - How to install on Linux (Debian)

2009-08-21T18:24:00.002+01:00

O Dropbox é uma ferramenta que sincroniza ficheiros entre vários computadores, tenham eles, Linux, Windows, MAC, ou mesmo iPhone*.
O funcionamento é muito simples, e passa por existir um serviço a correr em memória que sincroniza uma pasta seleccionada durante a instalação com um servidor remoto. Assim, sempre que se dá uma alteração dentro dessa pasta, o serviço vai sincronizar com o servidor do Dropbox. E mais, podem ter o serviço do Dropbox instalado em vários computadores, e assim, terem a informação sempre sincronizada.

*Até à data que este artigo foi publicado a versão para iPhone ainda se encontrava em desenvolvimento.

The Dropbox is a tool that synchronizes files between multiple computers, they have, Linux, Windows, MAC, or even iPhone *.
The operation is very simple, and goes through there is a service running in memory that synchronizes a folder selected during installation with a remote server. Thus, whenever a change occurs within that folder, the service will sync with the Dropbox server. Plus, the service may have the Dropbox installed on multiple computers, and thus always have the information synchronized.

* To date this article was published a version for iPhone is still under development.

ESXi - Backups

2009-07-05T17:42:00.001+01:00

The ESXi is a free operating system based on the Linux for VMWare virtual machines (VM). The big difference for the VMWare server, is that it runs directly on a layer of hardware, or you do not need an operating system (OS) by using the "eat" physical resources of the server. The ESXi is very light and takes only a few Mega Bytes.
In this article, I will not focus on the installation of ESX and its remote management console, I only focus on the use of a script to backup copies of virtual machines (VM), in an ESX server.

There are also the ESX, which is the commercial version of the OS, and obviously has but features.

The requirements for the tutorial that follows are: ESX and installed PuTTY (or other tool remote connection over SSH);

Tutorial:
1 - Enable SSH access:
In the console of ESXi press ALT + F1 and type the word "unsupported".
Then enter the root password. After that it gets access to bash OS ESXi.

2 - Edit /etc /inetd.conf and uncomment the line #ssh (remove the #);

3 - Restart the ESXi server;

4 - Connect to the server by ssh:
ssh root@IP_ServidorESXi (for your OS is Linux)
If users of Windows : ( can use PuTTY to connect to ESX.

5 - With the command wget-download the script to the VMware ESXi.
ESXi3x Version:
wget http://communities.vmware.com/servlet/JiveServlet/download/8760-34-23594/ghettoVCB.sh
ESXi4x Version:
wget http://communities.vmware.com/servlet/JiveServlet/download/8760-34-23594/ghettoVCB.sh

6 - Edit the script and change some important parameters:

* VM_BACKUP_VOLUME = / vmfs / volumes / backup -> path (local or NFS) which will be the copies of the VM (Virtual Machines). It is recommended to keep a host / remote storage (for NFS).
* ENABLE_2GB_SPARSE = 0 -> = 1 if the copy is divided into files of 2GB.
* VM_BACKUP_ROTATION_COUNT = 3 -> Number of copies to save up to start over.
* VM_BACKUP_DIR_NAMING_CONVENTION -> Format of the name of the copy. It is recommended to leave as is.
* POWER_VM_DOWN_BEFORE_BACKUP = 0 -> = 0 if the copies are made with MV in production.
* ENABLE_HARD_POWER_OFF = 0 -> If = 0 is off. Lets force the closure of the MV if it has not closed during the specified time in ITER_TO_WAIT_SHUTDOWN.
* ITER_TO_WAIT_SHUTDOWN = 4 -> is not applied if the previous option is = 0; recommended to leave as is.

7 - Create vmbackups file with the name of the virtual machines that ESXi contains. Example:

ServerA
ServidorB
ServidorC

8 - Run the script:. / GhettoVCB.sh vmbackups
During the execution of the script will be shown a progress bar.

Recommendations:
- You can create a small script to call the eating presented in section 8 and put it in cron (. Weekly;. Daily; (..)) in order to automate the execution of backups.
- The copies directly to NFS can be slow, you can make them to a local directory and then copy them to a remote NFS shares, thus saving time in the backup copies of each MV.

Disable sudo (If you please)

If you do not like (like me) to be always using the command "If you please" in Linux, ie "sudo", and then you must enter a user password! That sucks, does not believe?
So, to disable the password prompt when you switch to root, you can do the following:

1 - sudo visudo
# User privilege specification
root ALL = (ALL) ALL
(Uncomment the previous line)

2 - add your user to sudo group in /etc/group

3 - From now on, whenever the command line, just do sudo su, and not you are prompted password:)

Warning: The team Aventux, advises not make this change in servers, where security must be taken into account too. Now on workstations is not so serious, anyway, it is your account and risk.

Note: This was tested on Debian. I think that also works in this based distros (Ubuntu and others). Other non-Debian distributions also must have a very similar process.

To conclude let one more tip. After making the settings described above, to set up a shortcut menu of programs so that no password is requested, putting sudo before the command. I give the example of Synaptic. It always asks to start the root password, then you must edit the configuration of the shortcut and change the field where it says "Command: synaptic" to "Command: sudo synaptic".

xrdp: Linux Remote Desktop Protocol

2009-05-24T01:14:00.006+01:00

At one time published an article, which can read here on remote display in Linux. Now, I will publish another way that allows remote connection to a machine with Linux. The big difference is that xrdp accepts connections from both linux and the mstsc (Microsoft Terminal Services Command) without the need to install a client application. Therefore, contrary to nxclient (http://adventux.blogspot.com/2009/02/connection-screen-on-remote-linux-or.html), this does not require the installation of a client on a machine with Windows or Linux operating system, as it works with existing customers ( rdesktop and mstsc).

Installation for Debian (or derivative):
sudo apt-get install xrdp

They can also install via Synaptic or another package manager.

Tutorial for installing Debian Lenny - Light / Minimal

2009-05-02T21:30:00.001+01:00

After long hours of research, I developed a tutorial for installation of Debian, version 5 (codename Lenny) with KDE and with key features being "levezinho" (light). What I mean is that with this tutorial we can install only what you want, do not be so subject to the installation of a multitude of packages, something that usually happens in most Linux distributions.

Requirements:
Internet connection.
Some experience of installing Linux operating systems.

Tutorial:
1 - Download a mini version of Debian: amd64 (for 64 bit processors, Core 2 Duo and AMD and the like), i386 (32-bit processors), Other ...
2 - Burn the ISO image downloaded to a CD.
3 - Boot from CD and start the installation.
4 - The following steps to select the country code of the keyboard, etc.. Choose where Portuguese-Portugal, if they wish to European Portuguese.
5 - should get the part of setting up partitions. You can choose guided or manual. I always choose manual settings and do the partitions. If in doubt just ask the help in the comments section.
6 - When you reach the part of the package selection should leave only selected "Standard System".
7 - After the installation is complete the system, restart it. Now comes the most important part of this turorial.
8 - To install the KDE 4.2 graphical environment you must insert the following sources in source.list of apt-get:
vim /etc/apt/source.lists

deb http://ftp.de.debian.org/debian/ sid main
deb-src http://ftp.de.debian.org/debian/ sid main
deb http://ftp.de.debian.org/debian/ testing main
deb-src http://ftp.de.debian.org/debian/ testing main

9 - Installing KDE 4.2 based, with the media and government:
apt-get update
apt-get install kdebase-runtime kdebase-workspace kdebase kdemultimedia kdeadmin kde-l10n-pt phono-backend-xine

10 - This step will not be mandatory, but advisable, because programs will need to decompress, view PDF's, surf the Internet, etc ...
apt-get install ark okular apt-get install iceweasel-l10n-pt-pt
apt-get install build-essential kernel-package linux-kernel-headers linux-headers-`uname-r`
reboot

And so we avoid a "carraga" package that we sometimes leave the operating system more slowly. Try, will see that staying with a distribution of Linux and fast, and I know they have questions about any of these steps, say or write :p

Firefox is iceweasel in Debian!

2009-05-02T21:10:00.000+01:00

Since I had to format the laptop due to a problem that arose in my ex-honey "Kubuntu and it did not address in any way, enjoyed and installed Debian. On Debian, a distribution of free and more stable world of Linux:)!
What I am sharing here is something very simple, the installation of Firefox, or better iceweasel.
Avoid the search for firefox in the official Debian repositories, because they will not find. The Web browser that have the look is iceweasel.

Installation version of PT, by command line:
sudo apt-get install iceweasel-l10n-pt-pt

Installation via Synaptic:
Entering and searching synaptic pot "iceweasel portuguese" and then select only the PT-PT version if they wish to European Portuguese.

Linux Remote Desktop

2009-02-12T23:31:00.001Z

The connection screen on remote Linux or remote desktop, as this feature is known, can be carried out almost as simple as paid in operating systems: P (Windows).
The application that enables this function, which today is essential for management of servers, the company's NXServer Italian NoMachine.
Do not worry about the legality, since the NoMachine has been kind enough to provide a free edition (for Linux and Solaris) that enables simultaneous connection of 2 users. Is not good? :)
The NoMachine offers with this application, the possibility of a complete solution for remote desktop. Imagine having a room of class or training, with PC's "old." The refurbishment of this room would be very demanding in financial terms. Then, with a good server and the NXServer whole room can be remodeled, with departure at a cost much lower, since the PC's "old" it will connect by remote desktop to the server. And yet another advantage to have a centralized administration of the entire room.

There is also a free implementation with GPL in http://freenx.berlios.de/.

Installation:
1 - Download (There are versions for 32 and 64bit).
2 - Install the 3 packages downloaded the following order:
-------------------------------------
# Dpkg-i *. deb nxclient
# Dpkg-i *. deb nxnode
# Dpkg-i nxserver *. deb
-------------------------------------

Note:
The NXServer is installed as a daemon (service), then commands can use the type: / etc / init.d / nxserver (start | stop | restart).

Connect to remote machine:
Normally during the installation was created a group called "NX Client for Linux" on the Internet from your menu. Otherwise, the application can start with / usr / NX / bin / nxclient. Then it is super intuitive:)

Migrated to Linux and miss Internet Explorer?

Of course, in my opinion, ie not enough to heels of Firefox, but it is only my opinion. Even so, ie can not exist, for small things, such as pages that only work in Internet Explorer, or even to, programmers who want to test their sites on multiple browsers.

The ie4linux is a script that facilitates the installation of Internet Explorer on Linux.

* Requirements:

Wine - "Windows Emulator" - Learn more here

Wine-Doors: The graphics component of Wine

2008-09-10T20:55:00.001+01:00

Some say that the Wine-Doors is a graphical component of Wine and some say that the Wine-Doors is a management tool for Windows packages. Basically, you can considererar the two settings.
The Wine-Doors offers a range of Windows applications can be installed so easy on Linux systems.
This tool even though it was developed for the Gnome platform, also works the same in KDE.

Some of the applications that Wine-Doors are available: Dreamweaver 8, Windows Media Player, CDex, Photoshop, Visual C + +, DCOM, Warcraft 3, Call of Dutty, Medal of Honor, Quake 4, among many others.

It should be noted that most of these applications need to leave. When you install Wine-Doors are to agree to a clause requiring the user to have a license of Windows.
Some applications such as Dreamweaver, are installed with a version with 30 days of experimentation, and the possibility of entering the serial number, and others, require the installation CD.

Some applications installed and tested successfully by the team Aventux:

* Dreamweaver 8
* CDex
* DCOM 98
* Various types of source

Installation:

* Download Wine-Doors http://www.wine-doors.org/wordpress/?page_id=3 of the installation file for your distribution. In the same address should check the dependencies. It is clear that Wine is a mandatory dependency. Then just run the downloaded file for the package. DEB and. RPM.
* For more information on the official website (http://www.wine-doors.org) or at: http://www.guiadohardware.net/dicas/wine-doors.html.

* Versions available: Tar, DEB (Debian / Ubuntu) and RPM (Fedora).

Features:

* No Wine-Doors, you can filter the applications by: available, installed, and all queued to install.
* Update the list of packages.
* Kill the processes Wine.
* Restart the Wine.

Wormux - A clone of the Worms

2008-09-09T00:27:00.001+01:00

If at times the hours spent playing Worms, and when think about it, feel a little nostalgia, then it is because they are in need of Wormux!

The Wormux is a clone of Worms. I have tried and I assure you it is very cool.

Install it via Ultamatix, but I think that also you can install through Synaptic (if someone try, you know, tell us).

Also tested in the Magic Box and also worked well.

A disadvantage to find in the game, is not able to play against the computer. You can play up to 4 players simultaneously, and networking, but unfortunately (at least not find the option), against the Pc does not.
The game has several scenarios which to choose.

Go play some that life is not all work:).

Ultamatix: The successor to Automatix

2008-09-08T19:24:00.001+01:00

How many of you have not shame that Automatix had suspended its activity? Many concert!

The Automatix is (was) a tool that automates the installation of additional applications such as codecs, libraries, fontets, controllers/rivers, among others. This tool of great usefulness to users of K/Ubuntu has been discontinued from version 8.04, due to lack of availability of Automatixa team to continue its development.

But ... in July this year (2008) came to the bottom in a light tunnel, the Ultamatix. This new tool can even be the successor to Automatix. and was released versions for K/Ubuntu, Ubuntu and Debian Unstable Ultimate.

Allows, to date, the installation of 101 applications, of which highlight a few:

* Media Players and Editors, Adobe Acrobat Reader; Additional fonts, MS fonts, and Red Hat Liberation fonts; Additional archiving tools (rar, unrar, ace, and 7zip, etc.). Skype, Google Earth, DVD Ripping software, and Codecs Plugins, Google Picasa, Wine & Wine doors; NON-FREE w32codecs and DVD codecs, OpenOffice Clipart, Game Alien Arena 2007; Amoebax Game, Game ATanks; NTFS Read / Write Support;

Can give the rest of the applications supported in http://ultamatix.com/.

In terms of installation is greatly simplified, and once installed, is available wide range of tools, applications and games! Yes, well read, Games!

So let us install it:
1 - Download the website: http://ultamatix.com/#download.
2 - Run the downloaded file (package. DEB).

The next step is to take advantage of all the applications provided by Ultamatix:).

Because not everything is roses, "the team Aventux, alert to the fact that some codecs may not be distributed freely in our country, it should inform themselves about the possible need to pay copyright.
But another is that the use of unofficial repositories can bring problems, because some may not be reliable.
Apart from these drawbacks, we continue to advise, so try and then come comment on your experience here.

The WINE is not an emulator!

2008-09-07T17:01:00.000+01:00

Vai um copo?!

The Wine is an open source project that was born to give the possibility to run Windows applications on Linux operating systems. The Wine is more than an emulator, a time that you can understand that an emulator has to do with virtualization! From this, the Windows applications would be implemented in a virtualised, and therefore would be slower!
The Wine can carry to the field of Linux applications to Windows, which are executed as if the operating system for which they were manufactured. Surprised! Yeah, there is only a "very small" problem, in my angles course, is the stability of the programs running on Wine. At least I still can not run with 100% stability for example Microsoft Office 2003 and 2007. Word is that the stability is better, now when you go to Excel, the thing has changed a little picture! And then when we think in Outlook, you forget! Forget, is so to speak, remember, search and try and find out if the guys say here:). We are here waiting:). In any case there is a good alternative to Microsoft Office, which is Open Office, which I use and is very good. And an alternative to Outlook, there is the Evolution and Kmail, and others ...

As part of this instability, it is noted that there are many applications that run with great stability. Typically, the more simple the program is more likely he is to run smoothly on Wine.

Applications tested by team Aventux:
Can you run some stability with the following applications:

* Packet Tracer 4.1
* EyeDefender
* Putty
* Microsoft Office 2003: Word, Excel, Access, PowerPoint, Publisher, Picture Manager.
* ... (constantly updated)

We can not and never has been running successfully:

* Microsoft Outlook 2003 and 2007
* Google Chrome
* MSN Messenger (including the Live version)
* ... (constantly updated)

Installing the Wine?
Kubuntu 8.04 and Caixa Magica 12, and probably later versions, just go to Synaptic and find the Wine package, select and install.

Or, with the apt-get: sudo apt-get install wine

After the installation of Wine, should be available the following shortcuts in the group of programs Wine:

* Programs - Where are the shortcuts to Windows applications.
Browse * c: \ Drive - Explore the drive [c: \] - The Wine emulates the directory / home / USER / .wine / drive_c # as if they were disk [c: \].
* Wine Set - is an API which can, among other funcionalideades, add DLL's and configure the behavior of applications that work with Wine. As shown in the figure below, the application starts with Packet Tracer if in Windows XP.

Note: If an application does not run on Windows Xp so, should test the other modes, even if it seems a strange way for the application that is trying to use. I happened, for example, have to put a recent application of the boot as if Windows 98, because in none of the other modes worked!

K/Ubuntu: How to add sources/types of letter

2008-09-05T23:21:00.000+01:00

I found a good post this topic because, I went several times to "anhar" when I needed to add a font to my OS of choice:), I even got to lose a good 10m to search on google ...
But ready, look no further! It is very easy ... Just open the Konqueror or Dolphin in the address bar and put fonts: /, easy huh! Then just drag it to the source.

When you enter fonts: / should occur two areas, one personal and one of the system. First, it serves only to add fonts to the user that is in session, the other affects all users, therefore, the latter of administration privileges are required when adding new sources.

This procedure also works in the Magic Box, at least in KDE version and should work in many other, but at least those I tried.

Since the issue is fonts, take and leave a few addresses for download:

Gnome ISO Mounter (Gmount-iso)

2008-09-04T08:36:00.000+01:00

Surely you already gave way mount an ISO image in a directory? If yes, this publication (post) topic is for you!
Can install the iso-utility Gmount, already available in the repositories K / Ubuntu. Just go to synaptic (who is, I install) or the Adept Installer and install ... If you do not remember how to install a package, read the publication: http://adventux.blogspot.com/2008/10/teste2.html

As you can see in the following figure, the iso-Gmount is very simple to work:
Chooses to file (. ISO) and then choose the directory (mount point).
Possibly, they must first create the directory you want to mount image. Usually it is mounted on / media / whatever or / mnt / whatever, where "whatever" is the name they give to the directory that will have the contents of the ISO image.
This utility also allows you to show the ISO images already and are mounted and logically disassemble one.

It should be noted that the iso-Gmount is part of Gnome, but as I mentioned in previous publications, typically, the programs worked well in the Gnome Kde and vice versa. This is very good because we get a wider range of possible applications for our system: D.

What about Google Chrome? Sure already heard!
To begin with, in my opinion has great control, which is not getting out (02-September-2008) also a Linux version for community testing! I do not like using Windows, it is difficult to assess a browser so promising as this. Yes, assess, because so read the product is still far from the final version!
Certainly, there will be a Linux version and a MAC, but not for now! Decided they (Google) launched a version for Windows only (XP and Vista) ... 's wrong "because we have well water in your mouth! So it will to install a "XPzito", only to experience this scene (pardon the term: P).

An effort to install Google Chrome on Linux ...
Can you tell me that even in Arm artist and I was trying to install this new browser on Linux, using the Wine emulator! I tried, tried ... copied the directory of an already installed Windows (: P) and nothing. Changed settings in Wine and nothing! Simply not run, nor was any message: (.
I then got a call, who can say to the community! Are not only with the knowledge for you! eheh!

KolourPaint

2008-09-02T07:29:00.000+01:00

For those who feel the lack of a tool for simple image editing, as it was (I say was, because not used: P) the Windows Paint, the KolourPaint was more similar to that found. And it seems to me that there must be something so similar as this, to see has all the features that the Paint and have some more. In terms of robustness, speed of work and interface is similar to its homonym.

This little tool is perfect for small changes in images, that these changes do not need a powerful image-editing program such as Gimp or Photoshop.

Although the KolourPaint now part of the Kubuntu repositories, here is the same official address: http://superdownloads.uol.com.br/download/154/kolourpaint/.

To install in Kubuntu is just go to the Adept Installer (Add and Remove Programs) and search for and install KolourPaint.

In Ubuntu, in principle should also be installed from synaptics.

In CM (Magic Box), just select the repositories "Release" and then install from Synaptic.

Install with apt-get: sudo apt-get install kolourpaint

Manual KolourPaint: http://docs.kde.org/stable/pt_BR/kdegraphics/kolourpaint/index.html

Simply access a network share ...

2008-09-01T20:49:00.000+01:00

Accessing Samba shares / Windows is so easy in Kubuntu and Windows! Disbelief?
Then try opening Konqueror (the default browser of Kubuntu) and at put \ ip_da_máquina or \\ nome_da_máquina. Thus, konqueror automatically converts the "\\" to "smb: //" making this task be more transparent to a user who is accustomed to Windows (Windows).
It is clear that over time, begins to use more often "smb: //" instead of "\ ", then, is the rating of the Linux root.
They can also create shortcuts on the desktop, pointing to network shares, and very similar to Windows XP:). Click the right mouse button on the desktop -> Create New -> Shortcut to Location (URL), and only!

smbmount

For more advanced users can also mount a network share a point of your disk (ie a directory).
And so, here is the recipe:
1 - Create a directory. In my case, usually with a name-server network "in / media, with the entire path on / media / SERVER-NETWORK /. In turn, within-NETWORK SERVERS, create a directory for each share they intend to mount. Example: SERVIDORES-REDE/Servidor1.
2 - Run the command:
sudo smbmount //ip_servidor/pasta_partilhada/media/SERVIDORES-REDE/Servidor1-o username = jose
3 - Create a shortcut on the desktop to /media/server-network for a fast and direct access to network shares. Can even change the icon of this shortcut to identify the best! Well, if your environment is like mine, is full of shortcuts: P.

If they have the command smbmount can install it running: sudo apt-get install smbfs or by the package manager (eg Synaptic).

Package Systems

2008-08-27T21:03:00.000+01:00

A major difficulty in adapting to any Linux distribution, is to understand your installation system packages.
In K / Ubuntu, ie the distribution of the moment: P, the manager of packages is apt-get (not undoing of other distributions, but this is what I am using). The tool itself runs Debian packages Packeg - dpkg, which as you see, was a system adopted from the Debian distribution, as the whole Ubuntu.
In Windows, the standard is to install the application through removable media (CD, flash memories, etc.) or download the application from the Internet and then install. On Linux you can do exactly the same way, but what differs is the ability to install applications from repositories on the Internet somewhere (is not good.) The repositories are places where they are saved many programs, tools, utilities for Linux., Etc ...
Usually differ from the distribution repositories for distribution. Later, you'll see here a topic about some extra repositories (ie non-official repositories for K / Ubuntu).
In this way we avoid to have saved on CD's, DVD's, disks, "TeraGigas," floppies:), among others ...
In the Kubuntu distribution, has released the Adept Installer which is just a graphical interface for apt-get. Just us into this tool (the shortcut to the description that Add / Remove Programs) and inserting the name in the application, or only the initial letters, and follow ...
As shown in the figure below it was a messenger type program, the Emesene to install.

Another very good package manager (even higher than the Adept) is Synaptic. This can be installed in many distributions (Ubuntu, Kubuntu, Suse, CM, etc ...). But on this manager will soon only a topic on it.

Tips for starting ...

2008-08-26T06:36:00.000+01:00

When it is in principle all councils are few ... So here are some. of who has passed the "as passas do Algarve" to take this to function as it should be. Wait! It was not so bad!

The 5 basic advice:
1 - Download Kubunto:
latest version (http://www.kubuntu.org/getkubuntu/download).
or
1 - Download CM:
latest version (http://www2.caixamagica.pt/pag/b_down00.php)
2 - Install, taking care to the entire installation wizard, especially during the creation of partitions.
3 - Connecting the system to the Internet, and apply the updates that you feel necessary Adept Installer (There is an icon appears in the lower right corner with updates missing).
4 - Start using Windows as if they were, and little by little, trying to resolve difficulties and problems that arise, one at a time.
5 - Do not quit. This is important because this stage will miss the beauty of Windows XP. But sure, later this nostalgia will disappear.

Note: In this post, I only download two distributions because they are the two I have been testing / evaluation / work. Obviously there is no time to test all: (the ones that exist. So here are also other well known and used: openSUSE [1], Alinex [2] Fedora [3], etc ...

2008-08-07T07:56:00.000+01:00

Well, start by saying that I am not pro in linux! This is just to clarify, not come here to build me xico in with yet another smart blog about linux!
Yes come on my own experience. And my experience is only my experience, not even to be "some experience". Therefore assumes that the word "some" already includes plenty of fruit!

Started me more seriously in the discipline of Linux a Bachelor of Computer Science and Communications, which took in EStG (www.estg.ipleiria.pt).

Then reigned (in the middle where I was) the Fedora distribution and was by that I started. The classes were taught in Fedora and my final draft of course was in Fedora.

Now (August 2008),'m at the stage of Kubuntu! We have also walked the stage of Ubuntu! But KDE, by now convinced me:)

I live here then retract, or almost directly, with delays of several hours (which could be days: P), the adventure of an astronaut on a new planet - linux.

Yes, that is what they are thinking, migrate to linux and not use windows on both PC's at work (laptop and PC).
I have only one virtual machine with VMware on Windows XP that occasional use, moreover, is all in linux!

And this post was the start of this blog: D
Go now ...
