Linux uses Host Name to connect

 Tested on Ubuntu 20.04.

In Windows, the "computer name" can be used for network connection, so no matter how the IP is changed in the local network, the connection setting does not need to be changed. In Linux, there is the same thing, which is to use Host Name to connect.

During the Ubuntu installation process, you will need to fill in the "your computer name". In fact, the Host Name is set, but it cannot be used to connect by default. This article gives examples of two ways to open it:

Install Samba

Samba is a commonly used communication component with Windows. If you use the nmbd component, it can support NetBIOS to allow various Windows applications to connect without complicated settings. If you use the Ubuntu desktop, just share any folder and you will be asked if you want to install Samba. Click Yes and you are done.

The command installation method is:

sudo apt-get install samba

This method is easy to use for small offices or small area networks. It should be noted that sometimes the host name ping will not work after samba settings are changed, and manual configuration is required.

BIND ISC

BIND is a world-renowned DNS Server software that directly configures /etc/named settings. Suitable for large-scale local network management.

After completion, you can use ping HOST_NAME to test, and replace HOST_NAME with the previous setting.

Getting started with Gradle-Grovvy language foundation

Image
  Why learn Grovvy The official recommended language of Gradle is Groovy, which is a jvm language. If you want to perform plug-in modules, hot repairs, complex construction systems, etc., you need a little understanding of Groovy. You don't need to learn the details of Groovvy. Generally, the benefits are too great. Low, like bloggers only use Gradle to build SpringBoot, and the main project language is not Groovy. There are quite a few Gradle users who have no basic concepts at all. Whenever they encounter a need or problem, they need to find it online. This is a misunderstanding. Gradle is not just a configuration script, I personally think that behind it is a combination of two languages: Groovy Language + Gradle DSL The DSL part can also be expanded. If you are using the Android ecosystem, there will also be Android DSL, a total of three. The full name of DSL is Domain Specific Language, that is, "domain specific language", which means that this language is not univer...

Linux Command Pipeline basic teaching

  The "command pipeline" (command pipeline) is a very powerful basic feature of the Linux ecosystem. It can cascade a variety of different commands and turn many basic commands into a programmable way to use, which is of great help in the operation of the system. When a general Linux command is executed, there will be three input and output data streams, namely: Standard input (code 0): input data required for program execution. Standard output (code 1): The output data produced by the normal execution of the program. Standard error output (code 2): A message used to notify the user when a program error occurs, or a message used to present the program status. When the Linux program is running, it looks like this: Standard input STDIN ==> Linux program ==> Standard output STDOUT ==> Standard error output STDERR We can use the redirection feature to change the flow of these data, and add a pipe to string together different Linux programs. Pipe Connect the input and out...

Gradle configuration Spring multi-project test

  For projects with multiple Gradle projects, if the main project is executing unit test, other sub-projects will be executed together, and some advanced settings are required. First refer to another article, use eclipse to configure two SpringBoot projects: lab-springboot, library1. Gradle references the level project First, modify the build.gradle of library1 and add these codes at the bottom of the file: configurations { // Gradle DSL // The names of the configurations which this configuration extends from. testOutput.extendsFrom (testImplementation) } task jarTest (type: Jar, dependsOn: testClasses) { from sourceSets.test.output classifier = 'test' // The classifier distinguishes different artifacts build from the same project. } artifacts { testOutput jarTest } Then modify the build.gradle of lab-springboot and add these codes at the bottom of the file. Note that there may be other codes in the dependencies: dependencies { im...
