The problem you are having is due to the different class-loaders in use. The Commons Net classes must be loaded by the same class-loader that loads the FTP task. Because the FTP task is loaded by Ant on start-up, you need to add the Commons Net to Ant’s classpath so that it is loaded by … Read more
After some experimentation I came up with this way to automate a secure FTP download in PowerShell. This script runs off the public test FTP server administered by Chilkat Software. So you can copy and paste this code and it will run without modification. $sourceuri = “ftp://ftp.secureftp-test.com/hamlet.zip” $targetpath = “C:\hamlet.zip” $username = “test” $password = … Read more
Use the FTPClient Class from the Apache Commons Net library. This is a snippet with an example: FTPClient client = new FTPClient(); FileInputStream fis = null; try { client.connect(“ftp.domain.com”); client.login(“admin”, “secret”); // // Create an InputStream of the file to be uploaded // String filename = “Touch.dat”; fis = new FileInputStream(filename); // // Store file … Read more
I know this is an old Post but I am adding here for future reference. Here is a solution that I found: private void DownloadFileFTP() { string inputfilepath = @”C:\Temp\FileName.exe”; string ftphost = “xxx.xx.x.xxx”; string ftpfilepath = “/Updater/Dir1/FileName.exe”; string ftpfullpath = “ftp://” + ftphost + ftpfilepath; using (WebClient request = new WebClient()) { request.Credentials = … Read more
Try using ftp.nlst(dir). However, note that if the folder is empty, it might throw an error: files = [] try: files = ftp.nlst() except ftplib.error_perm as resp: if str(resp) == “550 No files found”: print “No files in this directory” else: raise for f in files: print f
There’s no standard way to have the FTP server sort the files according to your (or any) criteria. Though some FTP servers, notably the ProFTPD and vsftpd, support proprietary flags with the LIST/NLST command to sort the entries. Both these servers support the -t flag to sort the files by a modification time: LIST -t … Read more
Before you start downloading check for the existence of the file on the local filesystem. If it exists, then get the size and use that for the ContentOffset member of the FtpWebRequest object. This functionality may not be supported by the FTP server, though.
Try this: $ftp = [System.Net.FtpWebRequest]::Create(“ftp://username:[email protected]/camera/temp.jpg”) $ftp.KeepAlive = $true $ftp.UsePassive = $true $ftp.Method = “Rename” $ftp.RenameTo = “camera/temp1.jpg” $ftp.UseBinary = $true $response = [System.Net.FtpWebResponse] $ftp.GetResponse()
All protocol implementations in Apache Commons Net, including FTPClient, derive from SocketClient, which has a method addProtocolCommandListener. You can pass it an implementation of ProtocolCommandListener to implement logging. There’s a ready-made implementation PrintCommandListener, which prints the protocol log to provided PrintStream. With a code like this: ftpClient.addProtocolCommandListener( new PrintCommandListener( new PrintWriter(new OutputStreamWriter(System.out, “UTF-8”)), true)); …, … Read more
Make sure to login to the ftp server first. After this, use retrbinary which pulls the file in binary mode. It uses a callback on each chunk of the file. You can use this to load it into a string. from ftplib import FTP ftp = FTP(‘ftp.ncbi.nlm.nih.gov’) ftp.login() # Username: anonymous password: anonymous@ # Setup … Read more
