[英]Apache MINA SFTP Example
我正在嘗試設置一個具有多個用戶的 SFTP 服務器,每個用戶都有自己的主目錄。
我閱讀了這個答案,其中解釋了如何為單個用戶設置虛擬目錄,但我不確定如何讓多個用戶各自擁有自己的主目錄。
有人可以告訴我該怎么做嗎?
我終於讓它工作了。 這是一個工作示例:
pom.xml
<dependency>
<groupId>org.apache.sshd</groupId>
<artifactId>sshd-core</artifactId>
<version>0.14.0</version>
</dependency>
測試.java
import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.apache.sshd.SshServer;
import org.apache.sshd.common.NamedFactory;
import org.apache.sshd.common.file.virtualfs.VirtualFileSystemFactory;
import org.apache.sshd.server.Command;
import org.apache.sshd.server.PasswordAuthenticator;
import org.apache.sshd.server.UserAuth;
import org.apache.sshd.server.auth.UserAuthPassword;
import org.apache.sshd.server.command.ScpCommandFactory;
import org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider;
import org.apache.sshd.server.session.ServerSession;
import org.apache.sshd.server.sftp.SftpSubsystem;
public class Test {
public static void main(String args[]) {
try {
Runtime.getRuntime().exec("sudo fuser -k " + "2222" + "/tcp");
} catch (IOException ex) {
Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
}
File TEST = new File("test");
File ADMIN = new File("admin");
File ERROR = new File("error");
TEST.mkdirs();
ADMIN.mkdirs();
ERROR.mkdirs();
SshServer sshServer = SshServer.setUpDefaultServer();
sshServer.setFileSystemFactory(new VirtualFileSystemFactory(ERROR.getAbsolutePath()));
sshServer.setPort(2222);
sshServer.setKeyPairProvider(new SimpleGeneratorHostKeyProvider(new File("my.pem").getAbsolutePath()));
sshServer.setCommandFactory(new ScpCommandFactory());
List<NamedFactory<UserAuth>> userAuthFactories = new ArrayList<>();
userAuthFactories.add(new UserAuthPassword.Factory());
sshServer.setUserAuthFactories(userAuthFactories);
sshServer.setPasswordAuthenticator(new PasswordAuthenticator() {
@Override
public boolean authenticate(String username, String password, ServerSession session) {
if ((username.equals("test")) && (password.equals("test"))) {
sshServer.setFileSystemFactory(new VirtualFileSystemFactory(TEST.getAbsolutePath()));
return true;
}
if ((username.equals("admin")) && (password.equals("admin"))) {
sshServer.setFileSystemFactory(new VirtualFileSystemFactory(ADMIN.getAbsolutePath()));
return true;
}
return false;
}
});
List<NamedFactory<Command>> namedFactoryList = new ArrayList<>();
namedFactoryList.add(new SftpSubsystem.Factory());
sshServer.setSubsystemFactories(namedFactoryList);
try {
sshServer.start();
} catch (IOException ex) {
Logger.getLogger(CarrierSFTPServer.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
以上的更新版本(從 sshd-core 的 1.4.0 開始)。 請注意,我沒有為主機密鑰提供程序指定文件,因為我的文件用於 Junit 集成測試。
List<NamedFactory<UserAuth>> userAuthFactories = new ArrayList<NamedFactory<UserAuth>>();
userAuthFactories.add(new UserAuthPasswordFactory());
List<NamedFactory<Command>> sftpCommandFactory = new ArrayList<NamedFactory<Command>>();
sftpCommandFactory.add(new SftpSubsystemFactory());
SshServer sshd = SshServer.setUpDefaultServer();
sshd.setPort(22);
sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider());
sshd.setUserAuthFactories(userAuthFactories);
sshd.setCommandFactory(new ScpCommandFactory());
sshd.setSubsystemFactories(sftpCommandFactory);
sshd.setPasswordAuthenticator(new PasswordAuthenticator() {
@Override
public boolean authenticate(String username, String password, ServerSession session) {
if ((username.equals("admin")) && (password.equals("admin"))) {
sshd.setFileSystemFactory(new VirtualFileSystemFactory(new File("C:\\devl").toPath()));
return true;
}
return false;
}
});
sshd.start();
對於 2.8.0 版本(依賴 GAV: org.apache.sshd:sshd-sftp:2.8.0
),這個文件為我提供了一個很好的資源:

我通常不指定端口,它似乎使用隨機端口。
