Apache mina sshd :: sFTP's advanced configuration and parameter description

Apache Mina SSHD is a library for SSH servers and clients for Java.It provides a safe file transmission protocol (SFTP).This article will introduce the advanced configuration and parameter description of the Apache Mina SSHD, and with some Java code examples to help readers better understand. 1. Add SSHD dependencies To use Apache Mina SSHD, you first need to add corresponding dependencies to the project construction file.The following is an example of using Maven to build a project: <dependency> <groupId>org.apache.sshd</groupId> <artifactId>sshd-core</artifactId> <version>2.7.0</version> </dependency> 2. Create the SFTP server To create a SFTP server, we need to define a class that inherits from `sftpsubsystemFactory`, and rewrite the method of` createSubsystem ().In this method, we can set some advanced configuration parameters.The following is an example: import org.apache.sshd.common.Factory; import org.apache.sshd.server.command.Command; import org.apache.sshd.server.subsystem.sftp.SftpSubsystemFactory; public class CustomSftpSubsystemFactory extends SftpSubsystemFactory { @Override public Command createSubsystem(Session session) { // Set the advanced configuration parameters of the SFTP server // You can set the file of SFTP here to open the limit, file upload/download speed, etc. // For example, set the maximum number of files to open is 100 session.setAttribute(SshConstants.MAX_OPEN_FILES, 100); return super.createSubsystem(session); } } 3. Start the SSH server To start a SSH server and use the SFTP server we define, we need to create an object of a `SSHSERVER` and set some configurations.The following is an example: import org.apache.sshd.common.util.security.SecurityUtils; import org.apache.sshd.server.SshServer; import org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider; import java.io.IOException; import java.nio.file.Paths; import java.security.GeneralSecurityException; public class SftpServerExample { public static void main(String[] args) throws IOException, GeneralSecurityException { // Initialize the security module of Apache Mina SSHD SecurityUtils.setRegisterBouncyCastle(true); // Create the SSH server SshServer sshd = SshServer.setUpDefaultServer(); // Set the advanced configuration parameters of the SSH server // You can set the port of SSH here, host key, subsystem factory, etc. // Set the monitor port of the SSH server as 2222 sshd.setPort(2222); // Set the storage path of the server key sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider(Paths.get("hostkey.ser"))); // Set the SFTP server sshd.setSubsystemFactories(Collections.singletonList(new CustomSftpSubsystemFactory())); // Start the SSH server sshd.start(); // Waiting for the program to terminate, for example, turn off the server through user input System.out.println("Press any key to stop the server..."); System.in.read(); // Close the SSH server sshd.stop(); } } In the above example, we set up the SSH server's monitoring port to 2222 by calling the method of calling the `setport ()` method, and use the `setKeypairprovider ()` method to set the storage path of the server key.Then, we add the custom SFTP server to the SSH server through the method of `setsubsystemFactories ()` ``). We can also set the senior configuration parameters of the SFTP server in the sftp server in the sftp server through the method of `session.settattribute ()` method.For example, we can set the maximum number of files to allow the SFTP server to open. This is a knowledge article about the high -end SFTP configuration and parameter description of Apache Mina SSHD.By using these configurations and parameters, you can better control and optimize the behavior and performance of the SFTP server.Hope this article will help you!
