I am trying to upload a file using SFTP protocol using C# using SSH.NET library. Below is the code I am using
FileInfo f=new FileInfo("C:\\mdu\\abcd.xml");
string uploadfile=f.FullName;
Console.WriteLine(f.Name);
Console.WriteLine("uploadfile"+uploadfile);
var client = new SftpClient(host, port, username, password);
client.Connect();
if(client.IsConnected){
Console.WriteLine("I AM CONNECTED");
}
var fileStream = new FileStream(uploadfile, FileMode.Open);
if(fileStream!=null){
Console.WriteLine("YOU ARE NOT NULL");
}
client.BufferSize = 4 * 1024;
client.UploadFile(fileStream, f.Name,null);
client.Disconnect();
client.Dispose();
I am able to connect and the filestream
is also not NULL. But I am getting PermissionDeniedException
while attempting to upload a file.
Unhandled Exception: Renci.SshNet.Common.SftpPermissionDeniedException: Permission denied
at Renci.SshNet.Sftp.SftpSession.RequestOpen(String path, Flags flags, Boolean nullOnError)
at Renci.SshNet.SftpClient.InternalUploadFile(Stream input, String path, Flags flags, SftpUploadAsyncResult asyncResult, Action`1 uploadCallback)
at Renci.SshNet.SftpClient.UploadFile(Stream input, String path, Boolean canOverride, Action`1 uploadCallback)
at Renci.SshNet.SftpClient.UploadFile(Stream input, String path, Action`1 uploadCallback)
at movemsi.Program.UploadFile()
at movemsi.Program.Main(String[] args)
Is there any settings I am missing from the above code. Any help is much appreciated.
You need to specify a full path to upload the file to.
For example:
client.UploadFile(fileStream, "/home/user/" + f.Name, null);
Without the path, the SFTP server probably tries to write the file to a root folder or other folder that you do not have a write access to (hence the Permission denied).
