"ControlSocket.Validate reply" when trnsferrg file

Question

Hi,
I'm trying to upload a blm file on the ftp server.
At the time of upload i'm getting an exception: com.enterprisedt.net.ftp.FTPException: command not implemented.
at com.enterprisedt.net.ftp.FTPControlSocket.validateReply(FTPControlSocket.java:821)
at com.enterprisedt.net.ftp.FTPControlSocket.createDataSocketPASV(FTPControlSocket.java:531)
at com.enterprisedt.net.ftp.FTPControlSocket.createDataSocket(FTPControlSocket.java:401)
at com.enterprisedt.net.ftp.FTPClient.initPut(FTPClient.java:1423)
at com.enterprisedt.net.ftp.FTPClient.putData(FTPClient.java:1500)
at com.enterprisedt.net.ftp.FTPClient.putData(FTPClient.java:1480)
at com.enterprisedt.net.ftp.FTPClient.put(FTPClient.java:1306)
at com.enterprisedt.net.ftp.FTPClient.put(FTPClient.java:1278)

any idea why is this happening? since this class works fine for all the servers except for only one.

Answer 1

Most likely the client is issuing a command that is not supported by the server. If you enabled logging you should be able to see which command it's having problems with. If you post the last part of the log here we should be able to tell you.
