Good afteroon,
I'm working on a java project and I'm going to use JSch for SFTP connection.
My test class worked fine when I used user/pass authentication, while it
ends with "*Auth fail*" when I try to switch to user/key authentication.
If I manually connect to the server using OpenSSH client it works, so SSH
server should work and accept the key.
I set up a simple logger, from its output it seems JSch skips publickey
method... without errors.
Where am I wrong? Thanks!
My code:
---
public class JSchTest {
public JSchTest() {
JSch jsch = new JSch();
JSch.setLogger(new MyLogger());
try {
jsch.addIdentity("C:\\id_dsa");
} catch (JSchException e) {
e.printStackTrace();
System.exit(1);
}
Session session = null;
try {
session = jsch.getSession("myuser", "myhost");
} catch (JSchException e) {
e.printStackTrace();
System.exit(1);
}
Properties properties = new Properties();
properties.put("StrictHostKeyChecking", "no");
session.setConfig(properties);
try {
session.connect();
System.out.println("Connected!");
} catch (JSchException e) {
e.printStackTrace();
System.exit(1);
}
System.exit(0);
}
