我正在嘗試通過本地端口轉發建立套接字連接。流程是：客戶端 --> SSHhost --> TargetHost試圖通過端口轉發來實現這一點，但不斷收到 IllegalStateException: Can't connect to rHost 錯誤。我測試過遠程主機確實直接接受連接，我的用例是通過 SSHhost 連接。不確定哪里出了問題，或者我愿意接受不同的方法或建議？謝謝。 try { jsch.addIdentity(privateKeyPath); session = jsch.getSession(username, hostL, port); session.setConfig("PreferredAuthentications", "publickey,keyboard-interactive,password"); java.util.Properties config = new java.util.Properties(); session.setConfig(config); } catch (JSchException e) { throw new RuntimeException("Failed to create Jsch Session object.", e); } try { session.connect(); session.setPortForwardingL(8080, rHost, rPort); try (Socket s = new Socket()) { s.connect(new InetSocketAddress(rHost, 8080), timeout); } catch (Exception e) { String errText = String.format("Can't connect to rHost") throw new IllegalStateException(errText); } session.disconnect(); } catch (JSchException e) { throw new RuntimeException("Error durring session connection ); }

您需要更改以下行
s.connect(new InetSocketAddress(rHost, 8080), timeout);
到
s.connect(new InetSocketAddress("localhost", 8080), timeout);
因為你在使用該方法時實際上已經將本地主機端口 8080 映射到遠程主機端口session.setPortForwardingL(8080, rHost, rPort);
你可以試試這段代碼
try {
jsch.addIdentity(privateKeyPath);
session = jsch.getSession(username, hostL, port);
session.setConfig("PreferredAuthentications", "publickey,keyboard-interactive,password");
session.setConfig("StrictHostKeyChecking", "no");
session.connect();
session.setPortForwardingL(8080, rHost, rPort);
Socket s = new Socket();
s.connect(new InetSocketAddress("localhost", 8080), timeout);
session.disconnect();
} catch (JSchException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
