[英]Connect to a server with keyboard-interactive password authentication using jsch
[英]Connect to server without username or password using JSch
我正在使用com.jcraft.jsch.JSch創建SFTP連接。
我的SSH密鑰設置為我無需用戶名或密碼即可直接SSH到服務器的位置。
ssh test_server
我的公鑰在me@test_server:~/.ssh/
中的authorized_key文件中me@test_server:~/.ssh/
我的本地計算機上的SSH密鑰位於C:\\cygwin\\home\\me\\.ssh\\
另外,我在此目錄中還有一個配置文件和一個known_hosts
文件。
Host test_server
User user_name
HostName test_server.domain.com
ForwardAgent yes
要仔細檢查,我確保C:\\cygwin\\home\\me\\.ssh
中的C:\\cygwin\\home\\me\\.ssh
位於遠程服務器的authorized_keys
文件中。
我正在開發一個創建文件的GUI程序。 有了該文件,我希望能夠將其存儲在遠程服務器上,並將其放置在具有SFTP的文件夾中。 我該怎么做?
這是我到目前為止的內容:
public static void main(String[] arg) {
try {
JSch jsch = new JSch();
String user = "";
String host = "test_server";
int port = 22;
String privateKey = "C:/cygwin/home/me/.ssh/id_rsa";
jsch.addIdentity(privateKey);
System.out.println("identity added ");
Session session = jsch.getSession("", host);
System.out.println("session created.");
session.connect();
System.out.println("session connected.....");
Channel channel = session.openChannel("sftp");
channel.setInputStream(System.in);
channel.setOutputStream(System.out);
channel.connect();
System.out.println("shell channel connected....");
ChannelSftp c = (ChannelSftp) channel;
String fileName = "test.txt";
c.put(fileName, "./in/");
c.exit();
System.out.println("done");
} catch (Exception e) {
System.err.println(e);
}
}
我一直收到
com.jcraft.jsch.JSchException:驗證失敗錯誤。
有人知道解決方案嗎?
其他信息(這可能有用...不確定):
當我打開cmd時,它將帶我到C:\\Users\\me
。
但是,當我通過“ pwd”命令時,它會打印出/cygdrive/c/Users/me
。
我也願意接受任何新庫,或者也許只是一種更好的方法。
非常感謝!

您沒有在ssh
命令行上顯式指定用戶名的事實並不表示沒有使用用戶名。
默認情況下, ssh
隱式使用本地用戶名。 JSch不會那樣做。 即使與本地用戶名相同,也必須明確指定用戶名。
