java - net.schmizz.sshj.transport.TransportException : Unable to reach a settlement

Question

我正在尝试使用 SSHJ 登录其他机器。下面的 PFA 代码(不包括 try/catch/finally block )。

Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
final SSHClient sshClient = new SSHClient();
sshClient.addHostKeyVerifier(new PromiscuousVerifier());
sshClient.connect("test-hostname");
sshClient.authPublickey("test-user", private_key_path);
Session session = sshClient.startSession();
Session.Command cmd = session.exec(TEST_SSH_COMMAND);
cmd.join(5, TimeUnit.SECONDS);
if(cmd.getExitStatus() == 0) {
   System.out.println("Success");
}

当我尝试执行上述程序时，出现以下错误

[reader] n.s.sshj.transport.TransportImpl - Dying because -net.schmizz.sshj.transport.TransportException: Unable to reach a settlement: [] and [aes128-ctr, aes192-ctr, aes256-ctr, arcfour256, arcfour128, aes128-cbc, 3des-cbc, blowfish-cbc, cast128-cbc, aes192-cbc, aes256-cbc, arcfour, rijndael-cbc@lysator.liu.se]

有人可以帮我调试这个问题吗？

谢谢。

Answer 1

我遇到了同样的问题，这是一个类加载问题。另一个库 (winzipaes) 依赖于另一个版本 auf BouncycaSTLe (bcprov-jdk16)，该版本似乎与 SSHJ 引用的 jdk15 版本有冲突。

明确排除 jdk16 版本对我有帮助(但是我还没有测试使用 winzipaes 的代码)。
