SSHJ - EC2 örneğine giriş anahtarı oturum açma

Question

SSHJ testlerindeki gibi görünen bir pem dosyası var (referans olarak görmüyor olmamasına rağmen): https://github.com/shikhar/sshj/blob/master/src/test/resources/hostkey.pem. Basitçe pem dosyası aracılığıyla bir EC2 örneğine (string olarak okunur), ancak sorun yaşamaya çalışın. Bunu yapan var mı?

SSHClient ssh = new SSHClient(); 
    ssh.connect("ec2-XXXXXXX.compute-1.amazonaws.com"); 
    ssh.authPublickey("ubuntu", getPemAsString("/Users/me/ec2.pem")); 
    final Session session = ssh.startSession(); 
    session.exec("echo -e \"test\" >> /home/ubuntu/testfile"); 

Hata aşağıdaki gibidir:

DÜZENLEME: Hala şanslar. AWS, giriş için özel anahtar ile yanlış bir şey mi yapıyor olmalı?

SSHClient ssh = new SSHClient(); 
ssh.connect("ec2-XXX.compute-1.amazonaws.com"); 
ssh.addHostKeyVerifier("dd:9c:XX:fa:6a:XX:32:6a:2b:c3:e7:bd:2b:15:26:5f:76:b6:‌​c4:fe"); 
ssh.authPublickey("ubuntu", getRSAPrivateKeyAsString("mypem")); // Must be wrong? 

final Session session = ssh.startSession(); 
session.exec("echo -e \"test\" >> /home/ubuntu/testfile"); 

Answer 1

Sizinle açma ediyor kullanıcı kimlik doğrulama değil, konak anahtarı doğrulama :) var

client.addHostKeyVerifier ("xx gibi bir şey: 0a: xx: b5: c2: fd: 44: 1d: e0: e4: fc: xx: 5f: f8: dd: f6 ") bağlanmadan önce.

Answer 2

Ben başarıyla kullanan bir Amazon EC2 örneğine bağladıysanız aşağıdaki:

final SSHClient ssh = new SSHClient(); 
ssh.addHostKeyVerifier("XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX"); 

ssh.connect("host"); 

PKCS8KeyFile keyFile = new PKCS8KeyFile(); 
keyFile.init(new File("server_pem.pem")); 
ssh.auth("ec2-user", new AuthPublickey(keyFile)); 

try { 
    final Session session = ssh.startSession(); 
    try { 
     final Command command = session.exec("whoami"); 
     String response = IOUtils.readFully(command.getInputStream()).toString(); 
     command.join(10, TimeUnit.SECONDS); 
     return response; 
    } finally { 
     session.close(); 
    } 
} finally { 
    ssh.disconnect(); 
}

Ben java.security.Security sınıfına BouncyCastleProvider eklendi kadar başlangıçta benim için işe yaramadı EC2 bağlanmak için verilen örnek . Benim (basitlik için Groovy yazılmış) çalıştı basit bir örnek:

@Grab(group='net.schmizz', module='sshj', version='0.8.1') 
@Grab(group='org.bouncycastle', module='bcprov-jdk16', version='1.46') 

import net.schmizz.sshj.* 
import net.schmizz.sshj.userauth.keyprovider.* 
import net.schmizz.sshj.common.* 
import net.schmizz.sshj.transport.verification.PromiscuousVerifier 
import net.schmizz.sshj.connection.channel.direct.Session 
import net.schmizz.sshj.connection.channel.direct.Session.Command 

import java.security.* 
import java.util.concurrent.TimeUnit 

Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); 

client = new SSHClient() 
client.addHostKeyVerifier(new PromiscuousVerifier()) 
client.connect("ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com") 

PKCS8KeyFile keyFile = new PKCS8KeyFile() 
keyFile.init(new File("/dev/ec2/key/mykey.pem")) 
client.authPublickey("ubuntu",keyFile) 

final Session session = client.startSession() 
final Command cmd = session.exec("whoami") 
String response = IOUtils.readFully(cmd.getInputStream()).toString() 
cmd.join(10, TimeUnit.SECONDS) 

println response //ubuntu 

session.close() 
client.disconnect()
