我在FTP服务器(ProFTPD 1.3.3a)上使用FTPClient读取数据时遇到问题,需要对数据通道进行加密.一切正常,没有加密在其他服务器上.
我的代码是:
FTPSClient ftpsClient = new FTPSClient("TLS",false); log.debug("using TLS"); FTPClientConfig ftpClientConfig = new FTPClientConfig(FTPClientConfig.SYST_UNIX); ftpClientConfig.setServerLanguageCode("de"); ftpsClient.configure(ftpClientConfig); ftpsClient.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out))); // outputs all conversation to the console ftpsClient.connect(host,21); ftpsClient.login(username,password); ftpsClient.enterLocalPassiveMode(); ftpsClient.changeWorkingDirectory(pathname); listNames = ftp.mlistDir(); ftpsClient.logout();
我从输出中得到的是
220 ProFTPD 1.3.3a Server (xxx) [xxx] AUTH TLS 234 AUTH TLS successful USER xxx 331 Password required for xxx PASS xxx 230 User xxx logged in CWD /www/catalog 250 CWD command successful PASV 227 Entering Passive Mode (xxx). MLSD 550 SSL/TLS required on the data channel QUIT 221 Goodbye.
知道如何配置FTPSClient在数据通道上使用TLS / SSL吗?非常感谢您的帮助!
