edtFtpj SFTP connectivity problem

Question

We are getting following error when we tried to connect one of our SFTP host.
The connection did not complete
com.enterprisedt.net.ftp.ssh.SSHFTPException: The SSH client has not yet connected to the server. The requested action cannot be performed until after a con
nection has been established.
at com.enterprisedt.net.ftp.ssh.SCPClient.checkConnection(Unknown Source)
at com.enterprisedt.net.ftp.ssh.SSHFTPClient.quit(Unknown Source)
at com.db.ftptest.FTPTest.performFtp(FTPTest.java:83)

Please see edtFtpj java code for the SFTP connectivity

SSHFTPClient ftp = new SSHFTPClient();
ftp.setConfigFlags(SSHFTPClient.ConfigFlags.DISABLE_CHMOD_AFTER_PUT); 
ftp.setRemoteHost(SFTP_HOST);
ftp.setRemotePort(sftp_port);
ftp.getProxySettings().setProxyAddress("socks-proxy-servert.com");
ftp.getProxySettings().setProxyPort(1080);
ftp.getProxySettings().setProxyType(ProxyType.SOCKS4);
ftp.connect();

We are able to connect successfully for the same SFTP host using following command
Via unix command line
sftp -v -o "Proxycommand=/usr/lib/ssh/ssh-socks5-proxy-connect -h socks-proxy-servert.com -p 1080 SFTP_HOST sftp_port" user@SFTP_HOST


We would highly appreciate your help in this regard.

Answer 1

Try SOCKS5 since that is how you are connecting successfully.

Then enable logging at the ALL level and send us the zipped log file.

Answer 2

Thank you for the response.we are getting same error even with SOCKS5 using edtFtpJ program.

Please advise.

Answer 3

Enable logging at the highest level for both clients and send us the zipped log files and we'll take a look.
