This task includes checking, fixing the file system, and adjusting the tree to fit the changes in the system, adding new storage devices, etc. Check your hard drive There is no problem with the file system when using FreeBSD under normal circumstances. However, in some cases, if the computer's power is cut off without a nor
In actual work, we often encounter the requirement to connect two local area networks in different locations. The use of FreeBSD IPSec tunnel method can easily connect two local area networks, and has good security. Here's a case to tell how to connect two local area networks in this way. Assume the following network structure: The two FreeBSD machines are configured with firewalls of two subnets, and I
Because FreeBSD is a multi-user system, it requires the administrator to do day-to-day maintenance, especially as a network server system, once because of lack of maintenance caused by downtime failure, will cause great losses. Even for a single user of the FreeBSD system, but also to perform these indispensable maintenance tasks, only because the system to personal use, then the maintenance requirements ne

I used to hear about how to compile the kernel, and I felt very excited. Haha, especially for free-developed operating systems like FreeBSD, it is very good. I can customize the kernel by myself. I just want to know how to get it, it can increase the speed and ensure security and stability, so I will try to customize the kernel. (I am also a newbie. If an error occurs in this article, please correct me !) The Free

I've seen a lot of developers mention that FreeBSD is a very good system for development, but it's mostly about the advantages of FreeBSD in a stand-alone development environment, but lately I've found that FreeBSD's advantage in development is not the only one. The use of FreeBSD in a development team can be a complete solution. In the stand-alone development en
packets can be handed over to the firewall for processing, the real strength of IPSec is its communication encryption. In view of this, I think it is necessary to talk about the use of IPSec for communication encryption. Therefore, I have written this article after a period of study. Taking FreeBSD as an example, I will explain how to use IPSec for encrypted communication with Windows/Unix, we hope to help security enthusiasts and BSD enthusiasts.Fir
