I am trying to connect a remote ftp server using Apache Commons FTP library, i am able to log into FTP server but after that i am not able to issue any command and getting following error when trying to retrieve file.
425 Can't build data connection: Connection refused.
but I am facing no issue while login using MS-DOS command prompt.
Do anybody know what would be the issue ?
Thanks.
Without seeing code this is a stab in the dark, but have you tried the following
client.enterLocalPassiveMode();
if you are uploading from a local machine to a remote FTP server. I remember I had a similar problem and doing the above worked

I'm trying to connect to MS SQL Server through IntelliJ IDEA.
After creating a new login in SSMS, confirming that it works fine and enabling all IPs in TCP/IP settings. (I added the 1433 port as well), I am getting an error when I try to connect to localhost:1433.
I'll attach a screenshot here, hoping that someone has an idea of what can I do.

Problem solved. The Microsoft drivers seem not to work, so I used JTDS instead. Thank you!

Disabled my antivirus.
Also added TLS1.1 and TLS 1.2 into .ini file.

Any help will be greatly appreciated.
Thanks in Advance.

I am getting the below given error while performing ftp from ubuntu machine to same machine. I have done the complete setup and able to transfer file using Filezilla. But while doing the same from code it is giving error. Below I have shown the code snippet.
String PROTOCOL= "SSL"; //I Have tried with TLS also
FTPSClient ftpsClient = new FTPSClient(PROTOCOL, false);
ftpsClient.setTrustManager(TrustManagerUtils.getAcceptAllTrustManager());
ftpsClient.connect("192.168.13.5",21);
ftpsClient.login(userName, password);
I am getting the error 530 Please login with USER and PASS. While connecting only. It is not even going to login statement.
Can somebody please point me out what I am doing wrong here?
I am getting the error 530 Please login with USER and PASS. While connecting only. It is not even going to login statement.
If it is not even going to the login statement the message might be caused by the server rejecting the AUTH TLS command which is used to upgrade the connection to SSL/TLS. This might indicate that the server does not support TLS at all.
... able to transfer file using Filezilla.
Are you sure that Filezilla did use FTP with TLS and not plain FTP or SFTP (which is file transfer using SSH, something completely different to FTPS)?
I'm not quite sure, but when you're saying you're using the server and the Client on one machine, you have to use localhost 127.0.0.1 as IP Adress
When I print the I.P. address of the system using InetAddress.getLocalHost(), I get user-VAIO/192.168.1.3 . Now, when I connect to derby using jdbc:derby://localhost:1527/mydatabase;create=true, it connects without any errors but when I connect the same using jdbc:derby://192.168.1.3:1527/mydatabase;create=true, it fails giving me the following exception:-
java.net.ConnectException : Error connecting to server 192.168.1.3 on port 1527 with message Connection refused: connect.
Any help will be appreciated.
When you start your Derby Network Server, you provide a value for the '-h' argument. You might not realize you are doing this, if you are using the packaged StartNetworkServer.bat file, but look inside the batch file, and you will see the -h argument there.
The batch file comes provided with the syntax '-h default' when you download Derby from the Apache website.
But you can change that, to say, for example, '-h 192.168.1.3', and then your Derby Network Server will accept connections that specify 'jdbc:derby://192.168.1.3/my/database'.
Note that if you want to accept such connections from other computers on the network, you will also have to adjust your Windows Firewall rules, as by default it will prevent such connections.
I want to upload file from my system to remote server as ftp.how i am to resolve this.I am using FTPClient client = new FTPClient(); and client.connect("sftp://something.com");But i am unable to connect it how i am check weather problem with my code or url.like ping command
I haven't used FTPClient (assume you mean Apache Commons FTPClient but a quick browse of apidocs shows two errors in your use:
The parameter to connect is server name, not url: client.connect("sftp://something.com") should be client.connect("something.com")
If you are using sftp you have to use FTPSClient
If you're connecting to an Sftp you might need to add the appropriate certificates (public/private keys) to the JVM where the code is running. Try your code on a regular FTP connection first, if that works, but not the sftp connections, it's almost sure is because of that.
