An essential feature for people who use or need a video conferencing room lies in the ease of use of the software that allows videoconferencing. Possibly a person seeking a service of videoconference over the Internet need to meet any of the following needs:-present products or services to customers that are anywhere in the world and at any time. -Provide training. -run conferences live on various topics. And as well as these, there may be other reasons why a person needs a videoconference room. In the market are varied videoconferencing systems, many of which require complex and lengthy processes of installation that makes it difficult for many users by limitations of your antivirus, firewall or proxies. The best programs for video conferencing are those that allow a quick and easy access via the web, from any browser. These systems have a great bonus if they are also compatible with all types of operating system, both Windows, as Linux, Mac Os, etc..
The truth is that access to the passwords of users is not easy, since encrypted, and the only way to manually are stored in a way it is guessing it. A technique to obtain passwords is through the use of sniffers i.e. programs that intercept our communications and recorded passwords. There are ways of speeding up this process, through a keylogger. However, when these hacker tools fail, you can resort to brute force. WIKIPEDIA defines brute force such as: how to recover a key testing all possible combinations until you find one that allows access. Despite what may seem, is one of the methods most used by hackers, which exploits the most recurring vulnerability in the security of the information: the human factor. Users do not have sufficiently strong passwords, such as different types of characters and numbers that involve a certain complexity.
On the contrary, to prevent forgetting your password, they prefer passwords easy to remember, but at the same time to guess. To this end, the hacker, they use tools that have dictionaries of passwords, whose function is to keep trying passwords one by one. However, as users, we know that only with a password, you cannot access a post, since that requires a user code. To achieve both the user code and password, through this type of attack, exists different tools like BrutusAET 2 to brute force passwords of FTP, Net Tools Essential to brute force passwords from network (NetBIOS) service, or John the Ripper Windows, Linux to brute force passwords hashed from Windows. A simple way of protecting a system against attacks brute-force or dictionary attacks is to establish a maximum number of attempts.
In this way the system automatically locks after a number of failed attempts to default. However, even though there is a lockout policy of account, or complexity of passwords which obliges to change it from time to time they are also easily predictable because they often consist of adding short sequences of numbers to the same original root. Therefore, most advisable would set policies of sufficiently strong passwords, by a specialized company. From Audea want to remind you that the best way to prevent a penalty or damage to our information systems, is to comply with all technical and legal requirements of the security of the information.

Great amount of licenses exists of free software and its agreement can be very diverse. Despite of general way we can divide the licenses in two great blocks according to its more important characteristics. First they would be those that do not impose any condition in his second redistribution (permissive licenses) and second they would be those that do yes it (robust licenses or copyleft). Copyleft initially was developed for the distribution of the computer science programs. Software, nowadays so known, as Linux, Open Office or FireFox were created like free programs under copyleft.
With time, copyleft has extended to very diverse scopes, besides the computer science one, also to music, the edition, the right, the art or the media. One of first and more known projects than restored the bases of the conditions for the licenses of copyleft was the project of free software devised by company GNU. It was in 1983 when Richard Stallman created a productive process of cooperation for the elaboration of a free operative program of any restriction derived from copyright. The project mainly consisted of the elaboration of a set of licenses that guaranteed that the software created by the equipment of Stallman stayed completely frees in all later versions. The participants in this process could use, share, modify or improve anyone of the free versions of this software being forced to put it at the disposal of the rest of the society without no restriction regarding their operation. Of this form he was wanted to prevent that once put to the service of all the community of users without no restriction somebody he could change these conditions. Unlike a program under the public dominion in which also changes can be realised, copyleft prevents that it turns somebody it into a privative program. In a software under the public dominion any person who introduced modifications in the same could distribute, it as own product, that is to say, the intermediary could break the chain of free use initiated by the author original and to begin to distribute the versions modified under its own copyright. In case of copyleft, whatever it uses the free program it tries and it to redistribute, with or without changes, it will have to grant to the following receiver the freedom to copy it or to modify it, guaranteeing at any moment the maintenance of these initial conditions.

Just one year short of Linux to become an adult. A majority of legal age, of course, because the maturity that has long reached. Sunday was yesterday when they met 17 years of Linux, from the day that its founder, Linus Torvalds, published the first public version of your video.
It’s funny to read the original message with the announcement, which noted that Linus This is a program for hackers by a hacker. His original intention was not to further tap into that a little bit and learn at the same time as it developed an operating system, while awaiting the appearance of Hurd, who had to be the GNU version ofUnix.
Per, for all of a sudden, Linux has achieved success while Hurd is still little more than vaporware. And what began as a project of a Finnish student has become a revolution.
Today there are few teams that do not have a version of Linux that can run on them, from computers to video and music players or mobile phones. His versatility and power made it happen.
And, although for the moment has failed to arrive in bulk to the desktop, where Windows is still the great exponent, important steps have been taken, especially with the launch of ultraportable, many of them equipped with a Linux distribution.
We have no other to congratulate the father of the child, Linus Torvalds, and thank him for everything that your operating system has done for us.

Following the entry a single Grub for all your Linux of the wonderful blog of FORAT, which explains how to create entries by hand in GRUB when you install multiple operating systems and you want to keep the original GRUB, I will let me for once disagree with him and put my way of doing this by writing here, I think it is a little easier and so I’ll give the example of Windows XP. When you have installed Linux and XP on the same machine, what we have in the MBR is the Manager of GRUB bootloader, and within this a title such as for example XP input. If edit that entry (by pressing e) from GRUB, we see these lines: root (hd0, 0) chainloader + 1 makeactive these lines what they do is pass control to the Manager the XP boot, which rather than being in the MBR is partition 1, hence the (hd0, 0). Therefore can do same for linux. Does put us in a typical scenario: 1? partition hda1 > Windows XP (with your bootloader partition hda1 2? partition) makeactive chainloader + 1 then just below enters it for Windows XP create a new for our Debian: title Debian Lenny root (hd0, 2) chainloader + 1 makeactive save, and restart and load GRUB from the MBR that of Ubuntu, will leave us three innings Ubuntu Windows XP Debian Lenny if pressed Debian Lenny does is charging us the hda3 partition Debian GRUBClick in the kernel by default and ready.
I see you 2 advantages to this method: you can install several operating systems, having the GRUB that we like in the MBR, and through this charge the GRUB of other operating systems. We don’t have to worry about updates. If you exit a new debian kernel and updates the GRUB does not pass anything, it does us well. The other way, we would have to return to editing the menu.lst with the new kernel. Although everything is of course improvable.
I accept suggestions and criticisms.
The first machines using the rare Shugart Associates System Interface (SASI) as their hard disk interface, the SUPER X68000 (CZ-604C) take the standard SCSI (small computer system interface). Due to the capabilities of hardware, hard drives SASI can have 10, 20 or 30 megabytes in size and logical partitions. Diskettes come in several formats, none of them natively readable by other platforms, so there are different utilities for reading MS-DOS, Windows 98 or Linux.<
Production of stamps for the stamp – this is one of the most popular services on the market of printing services. For the design of seals used several different technologies: laser engraving of rubber, photopolymer technology, curing, flash technology. Under the production of stamps for the stamp means the recovery. Typographical firms produce a production of stamps for stamp replacement of lost or degraded. Confidential orders to restore the stamps are accepted at any reasonable time for the customer.
The appropriate stamp will be precisely designed the original print. Also, like any tool, Printing has developed its service life. As time passes, print wear out, damaged, deformed, or even lost.
