IOError: [Errno 2] No such file - Paramiko put()

The IOError is local, so (for whatever reason) it seems that your local python cannot find localFile. Safety checking this before the call might help tracking down the problem:

if os.path.isfile(localFile):
    sftp.put(localFile, remoteFile)
else:
    raise IOError('Could not find localFile %s !!' % localFile)

If you're positive that localFile does exist, then this could just be a path problem - is localFile on an absolute or relative path? Either way, the if statement above will catch it.

EDIT

Tracing through the paramiko files shows that line 245 of sftp_client.py (the one throwing the exception) is actually

fr = self.file(remotepath, 'wb')

which is quite misleading as paramiko throws an IOError for a remote file! My best guess now is that remoteFile is either a missing directory or a directory you don't have access to.

Out of interest, can you list the remote dir

sftp.listdir(path=os.path.dirname(remoteFile))

to check that it's there (or maybe it's there and you can write to it)?


The put method has a confirm parameter which is enabled by default, which will do a stat on the file after transfer.

In my case, the remote server i was transferring the file to, immediately moved any transferred files to another location to get processed which was causing the stat to fail. Setting the confirm parameter to False resolved this.

def put(self, localpath, remotepath, callback=None, confirm=True):

From the paramiko source sftp_client.py:

:param bool confirm: whether to do a stat() on the file afterwards to confirm the file size (since 1.7.7)


It seems to be a remote folder permission problem. Although the remote folder was made before the file was uploaded, it appears the permissions on the folder were preventing an upload.

The problem is linked to this issue - if I set open permissions on the folder I'll be uploading to before I upload, the program can upload fine. Although for a permission issue I should be getting IOError: [Errno 13] Permission denied, since I made the changes I haven't encountered any errors.

I'm not sure if it's the response the server is giving Paramiko which is the issue, or a bug in Paramiko itself which is causing IOError: [Errno 2] No such file instead of a Errno 13, but this appears to have solved the problem.


Are you sure the directory has been created and it is your remote working directory? Paramiko has its own methods for creating new directories and navigating the remote file system. Consider using something like:

sftp.mkdir(remotedirectory)
sftp.chdir(remotedirectory)
sftp.put(localfile, remotefile)
