FTPConnection , exception on connect(); statement.

Question

I am trying to connect to a Siemens Switch/MSC in a mobile operator network. I have code sample in C# but it gives exception when i try to execute connect() statement. I am using edtFTPnet (for .net)
I can download the required files using windows ftp utility (command prompt). using ftp utility i simply login and give 'get TS.CPXX.WE1' and the file gets downloaded.

Following exception is observed when ftpObject.connect() is executed.
Command not implemented PRO01EL4 (code 502)

the code is here...

ftpConnection = new EnterpriseDT.Net.Ftp.FTPConnection();
ftpConnection.ServerAddress = ServerIP;
ftpConnection.UserName = UserName;
ftpConnection.Password = Password;
ftpConnection.LocalDirectory = Environment.CurrentDirectory;
ftpConnection.ConnectMode = EnterpriseDT.Net.Ftp.FTPConnectMode.ACTIVE;
ftpConnection.AutoLogin = true;                                
[b]ftpConnection.Connect();   [/b]                          
ftpConnection.DownloadFile(fileName, RemoteFile);

when i try to login to this system using FileZilla it has the following log.

Status: Connecting to 10.175.20.1:21...
Status: Connection established, waiting for welcome message...
Response: 220 SERVICE READY FOR NEW USER. PRO02OC0

Any help ?

Answer 1

Set AutoLogin = false, and call Login() after Connect()

Answer 2

Thanks dear,
It solved HALF problem, now i am able to connect/login but the next statement which is downloading file giving exception.

statement is :

ftpConnection.DownloadFile(fileName, RemoteFile);
// values of both parameters are ...
// fileName = "D:\\PAT-Software\\ECN\\prjCPLoad\\prjCPLoad\\bin\\Debug\\ftp\\MSC-5__02122010_0310__TS.CPXX.TH1.raw"
// RemoteFile "TS.CPXX.TH1"

Exception thrown:
Command not implemented PRO01EL4 (code 502)


StackTrace is :
Exception :: at EnterpriseDT.Net.Ftp.FTPClient.GetASCII(String localPath, String remoteFile)
at EnterpriseDT.Net.Ftp.FTPClient.Get(String localPath, String remoteFile)

Can you post the log file from ftp.exe (command line)? Set the mode to 'debug'

Answer 5

Ensure you are transferring in active mode. If it doesn't work in active mode post the fragment of the log file (from edtFTPnet) showing the error.

Answer 6

As you can see, i am using Active Connection Mode. and how can i get fragment of the log file from edtFTPnet ?

ftpConnection = new EnterpriseDT.Net.Ftp.FTPConnection(); 
ftpConnection.ServerAddress = ServerIP; 
ftpConnection.UserName = UserName; 
ftpConnection.Password = Password; 
ftpConnection.LocalDirectory = Environment.CurrentDirectory; 
[b]ftpConnection.ConnectMode = EnterpriseDT.Net.Ftp.FTPConnectMode.ACTIVE; [/b]
ftpConnection.AutoLogin = true;                                
[b]ftpConnection.Connect();   [/b]                          
ftpConnection.Login();                 
ftpConnection.DownloadFile(fileName, RemoteFile); 

Answer 7

Read the documentation or search these forums for logging.

Answer 8

however, i have done away with it by using simple windows ftp utility with a bunch of DOS commands...

It works perfect... 8)
