FtpConnectionCosedException: Verbindung ohne Hinweis geschlossen ⇐ Apache

[Anonymous]

Ich versuche, eine Verbindung mit FTP Server herzustellen, die von Docker Image bereitgestellt wird,
mit Apache Client: < /p>

Code: Select all

 import org.apache.commons.net.ftp.FTPClient

import java.io.IOException

object FtpClient {

def main(args: Array[String]): Unit = {

val ftpClient = new FTPClient()

try {
ftpClient.connect("localhost", 21)
val success = ftpClient.login("one", "1234")

if (success) {
println("Success connect")
}

} catch {
case e: IOException => throw new RuntimeException(e)
} finally {
//
}

}
}

Changing password for one
New password:
Bad password: too short
Retype password:
adduser: /ftp/one: No such file or directory
passwd: password for one changed by root
seems like pidfd_open syscall does not work, falling back to
polling
failed to watch for direct child exit (pidfd_open error): Operation not permitted

Vielleicht vermisse ich einige signifikante Verbindungseinstellungen?
