FileZilla SFTP Disconnected from Server

When connecting to an SFTP server using Java code, it's not uncommon to encounter issues that prevent a successful connection. One such issue is when the connection is unexpectedly closed by the foreign host, resulting in a disconnection. This problem was recently faced by a developer who was trying to connect to a local SFTP server using FileZilla configurations.

The developer used the following Java code to establish an SFTP connection:

```

Session session = jsch.getSession('test', 'localhost', 21);

JSch jsch = new JSch()

```

However, when executing this code, they encountered an error message indicating that the connection was closed by the foreign host. The full error message is as follows:

`connection is closed by foreign host`

This error is likely due to a misconfiguration or incompatibility between the Java code and the SFTP server. To troubleshoot this issue, it's essential to analyze the configuration settings used by FileZilla and compare them with those used in the Java code.

In the case of FileZilla, the user had successfully connected to the local SFTP server using the following configurations:

`FilleZilla server: (000017) 09:26:20 - (not logged in) (127.0.0.1)> Connected on port 21, sending welcome message.`

This suggests that the issue lies not with the FileZilla configuration but rather with the Java code used to establish the SFTP connection.

To resolve this problem, the developer will need to investigate and fix the configuration settings in their Java code to ensure compatibility with the local SFTP server. This may involve adjusting port numbers, usernames, passwords, or other parameters used during the connection process.

In summary, when facing issues with an SFTP connection using Java code, it's essential to carefully analyze the configuration settings and compare them with those used by FileZilla to identify any discrepancies that may be causing the disconnection.
