This article mainly describes the new important security mechanism in the FreeBSD 5.0 operating system, that is, the use of mandatory access control mechanism (MAC) and source code analysis, including mandatory access control framework and multilevel security (MLS) strategy. This section describes some of the things that you should do with the MAC framework and the MLS strategy, and how to use them effectively.
Mandatory access control (acronym MAC)
to accidentally trick, because this will often lead to the normal use of the network, it may be a small matter for family users, but for some scientific research, enterprises and institutions, the network may be disconnected for one minute. At the same time, the old computers that have been chased by stars for several years are mostly left out in the corner. These computers basically cannot run Win2000, so we cannot use the traditional method to take advantage of it, but with the

As the BSD Project (dragonflybsd, FreeBSD, NetBSD, and OpenBSD) grows, their misunderstandings are also increasing. Some of these are due to misunderstandings, while others are rumors intentionally spread.This page aims to clarify these misunderstandings as objectively and fairly as possible.

UNCLX FreeBSD is a very good UNIX, I used it for nearly two years, here are some of my installation experience for beginners to refer to.

You can go to FreeBSD's official website as well as its mirror image website to download, recommended download optical mirror, suffix name is ISO, after downloading conditional can be carved into a direct boot disk (in Nero, c
FreeBSD 7 will be the most important version of FreeBSD over the years, with a large number of new features and performance improvements.
FreeBSD is an advanced operating system that supports x86 compatibility (including pentium® and athlon™), AMD64 compatibility (including opteron™, athlon™64, and EM64T), ARM, IA-64, PC-98, and UltraSPARC The computer for the ®
Establish a file system
When the system load increases gradually, it is not enough to rely on the original file system space, more efficient way is to add new hard disk devices. This first requires changes to the hardware settings of the hard disk and its controllers, as well as the FreeBSD kernel configuration so that the hard disk can be installed on the computer and properly identified by the FreeBSD ke

As a BSDer, the most frequently transferred on the internet is UNIX-related forums. In the process of getting in touch with many new users, it was found that a considerable number of people were transferred from Windows (almost "the vast majority"), and they encountered many difficulties when learning FreeBSD, and even felt that UNIX systems were extremely difficult to use, here, I will summarize my experience for your reference.
The first problem is
1. I personally think that the author's understanding of Linux by MAX is not as deep as that of Solaris, I do not know whether or not he has the following content about Linux from his own code reading and analysis, or only from third-party documents without on-site verification; 2. I have tried my best to translate it as intended. Of course, I can't help but insert two sentences in the middle. 3. Whether I only read this article or read other things, I think it is important to keep my mind clear

If you need to copy a file from the second hard disk and format it as a UFS 2 file system, how can you mount the UFS 2 file system created by FreeBSD to the Ubuntu system?
UFS file systems are widely used in different operating systems (such as HP-UX, Sun Solaris), including FreeBSD. The following syntax is used to
Network capability is important in FreeBSD systems, and for a standard FreeBSD system, at least one network interface is needed to communicate with other computers. It supports token ring and FDDI, as well as wide area network connections such as common telephone dial-up connections, ISDN, ATM, and so on. As for the installation of the FreeBSD system, which has a

After the system finishes executing the RC startup script, FreeBSD will read the/etc/ttys file, start multiple virtual consoles as configured, and start the logon process login on the console to accept user logins. Users can switch between different consoles using function keys such as ALT-F1, Alt-f2, and ALT-F3. By default, there are 4 virtual consoles (where the fourth does not provide a logon service), up to 12 virtual consoles (limited by the 12 f
FreeBSD 5-current has just introduced a kernel dispatch unit scheduler called the Ule Scheduler. This scheduler is much more efficient in SMP systems than FreeBSD previous versions (currently, the scheduler is called the 4BSD Scheduler).
The new Ule Scheduler is designed more like a scheduler for operating systems such as Solaris and Linux. Solaris's SMP performance is very good this is one of its selling
