FreeBSD is an excellent UNIX operating system. It is famous for its excellent stability, security, and performance. It is one of the mainstream server operating systems. Not long ago, FreeBSD released a new major version FreeBSD 7.0, which added many outstanding features. Now we take the standard PC as an example to introduce the installation process of
Change work, mainly contact SuSE Redhat Aix These have the original service system, FreeBSD long not touched, and now quickly forget, yesterday under the FreeBSD 10来 play, found there are many new changes. So write a few articles about FreeBSD, hoping to let more people understand it.The environment is based on:Vmware 11 Please own BaiduFreeBSD 10:Http://mirrors.
System. Depending on the desktop system you choose, there are three versions available, Gnome-based Ubuntu, KDE-based Kubuntu, and XFC-based Xubuntu. Features are very friendly interface, easy to use, the hardware support is very comprehensive, is the most suitable for desktop system Linux distribution version.Gentoo, the Great Gentoo, is the youngest distribution in the world of Linux, and because of its youth, it is one of the reasons why Gentoo is known as the most perfect Linux distribution
The installation system is a complex process, one of the reasons is the variety of personal computer hardware, can be combined in a variety of ways, so it can cause complex installation problems.
Network Installation Method
In addition to using the installation CD to install FreeBSD, there are several other installation media to choose from, where network installation is also a very convenient way to install.
If the consumer is connected
other messy things. There is also a machine that has been granted root permission many years ago. (Ironically, it was a Linux machine, not Microsoft, and the machine never took any safety measures, and the lab keeper's brother put a rootkit on it.) When we found it, we replaced it with FreeBSD, and the root code was kept by us, and the machine was never invaded again. )
The lab now has 10 Windows XP machines and a
Objective
We may have seen many Linux operating on floppy disk, can run on floppy disk FreeBSD instead of less, although there are PICOBSD, however, many times Picobsd does not meet our needs, then can we make a floppy disk run on the FreeBSD system? The answer is yes. I am maintaining a floppy firewall project, which is a firewall system based on FreeBSD and IP

It is not freebsd, It is freenas7.2. Due to a problem with freenas installed for a friend, I studied how to operate raid1 in freebsd command mode yesterday and the night before. I should say how to configure freenas.
In fact, freebsd manual says:

Linux is a cute little penguin, while FreeBSD is a little devil with a fork. Do you often hear people confuse Linux and BSD systems? Yes, I often hear from new users and even the media. Of course, the two actually have many similarities. For example, they are all developed based on UNIX, and basically both systems are developed by non-profit organizations and teams, in addition, I would like to say tha
I believe you have heard of qemu. qemu is a well-known virtual machine like bochs. however, the performance and functions are relatively better than bochs. for example, why not run qemu when it supports ISO installation, DHCP gateway, and IMG images compatible with bochs? Haha, of course, there are also some shortcomings, but sometimes the operation is unstable, and the keyboard shortcut for switching the mouse is not properly designed, the two keys Ctrl + shift will be used first.
