我正在尝试设置一个具有多个用户的SFTP服务器,每个用户都有自己的主目录。
我阅读了this answer,其中解释了如何为单个用户设置虚拟目录,但我不确定如何让多个用户拥有自己的主目录。
有人可以告诉我该怎么做吗?

我终于开始工作了。这是一个有效的例子:

上面的更新版本(从sshd-core 1.4.0开始)。请注意,我没有为主机密钥提供程序指定文件,因为我的是用于Junit集成测试。
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();
