the virtual machine network is completely dependent on the network of the physical host. In this mode, the two systems do not process the same LAN and cannot directly ping the system. However, virtualbox can set port forwarding rules in Nat mode. By setting rules, the PC can connect to virtual machines in virtualbox.Practice

Byte order
Byte sequence refers to the storage order of data that occupies more than one byte in the memory. Generally, there are two types of byte sequence: small and large.Small-end byte orderLow-byte data is stored in the memory address and high-byte data is stored in the internal address;Large-end byte orderHigh-byte data is stored at the low address, and low-byte data is stored at the high address.
The PC based on the X86 platform is in the small byte order, while some embedded platforms ar

I found this on the internet and found that there were very few materials. Almost no one put forward substantive content. Recently, I started to do this part of the game. I have never developed such a thing before, so I had to analyze other people's systems in a simple way, A solution is designed based on your own understanding. I think this part of knowledge may be helpful to many people, so I made public the design of this solution. In fact, it is estimated that the solution is not even secure

The AMQ configuration file needs to be modified, and the client connection URI address should be modified accordingly. 4.

, the amount of data to be processed is much larger than that of the general switch. Therefore, the cache of the bridge is generally larger than that of the switch.
Notes:
1) Does the bridge need software assistance?
To answer this question, first look at the original bridge. In computer network (version 4), there is a saying like this: Traditionally, bridges usually contain a CPU, "forwarding-storage" is implemented by software. Oh,The previous bridge was like this.But now, due to the improveme

There are three solutions to this problem:
One is[Enable package configuration]To write the database connection information to the configuration file. No matter which user runs the package, the configuration file will be re-loaded, and the problem will naturally be solved.
The second is to reconfigure the Logon account of the SQL Agent service. By default, the Logon account of the SQL Server Agent service isNETWORK SERVICEYou only need to change it
One of the biggest features of Linux is its network stack. It was originally originated from the BSD network stack and has a very clean set of interfaces, which are well organized. Its interfaces range from protocol-independent layers (such as general Socket Layer interfaces or device layers) to specific layers of various network protocols. This article will explore the Linux network stack interface from the perspective of layering and introduce some of the main structures.
