Paramiko Python：IOError：[Errno 13] 权限被拒绝

Question

The Question:

Can I do something like:

self.sftp.put(sourceFilePath, final_destination, use_sudo=True)

I can make folders, but not files? Do I need to explicitly call sudo or set something in paramiko? Should I be copying the file to a permissable space and chowning? Is there a way to give paramikko sudoer without using keys or having to mess around with ssh.exec_command("sudo mv") ? What am I missing?

The Code:

class Ssh(object):

    def __init__(self):
        super(Ssh, self).__init__()

    def setup(self):
        '''Setup connection'''
        try:
            # DEBUG
            paramiko.common.logging.basicConfig(level=paramiko.common.DEBUG)
            #set username & password
            username = 'sgdevbox'
            password = MainFrame.ssh_pass
            host = '192.168.0.170'
            port = 22
            self.transport = paramiko.Transport((host, port))
            self.transport.connect(username = username, password = password)
            self.sftp = paramiko.SFTPClient.from_transport(self.transport)
            print(self.sftp.sock)
        except Exception, e:
            print(traceback.format_exc())

    def putFiles(self, sources, listingSku):
        '''
        Upload images to server along with all currentItemInfo, plus initials and date
        Basically build the auction and put it into the queue for verification
        '''
        print('\n# Ssh.putFiles() #')
        if isinstance(sources, unicode):
            sources = {sources,'True'}
        try:
            self.setup()
            destination = '/var/www'
            cwd = os.getcwd()
            for source in sources:
                filename = os.path.split(source)[-1]
                destinationFolder = listingSku
                final_path = posixpath.join(destination,destinationFolder)

                try:
                    self.sftp.mkdir(final_path, mode=777)
                except:
                    print(traceback.format_exc())
                final_destination = posixpath.join(final_path, filename)
                sourceFilePath = os.path.join(cwd,source)
                print('\n# Source Path: {}\n# Destination Path: {}\n\n'.format(sourceFilePath,final_destination))
                self.sftp.put(sourceFilePath, final_destination)
        except Exception, e:
            print(traceback.format_exc())
        return

Some of the posts are sort of old, but seemed to indicate that paramiko doesn't have it implemented? Fabric has a version implemented, but I am not sure about adding more dependencies.

(Pdb) import pkg_resources
(Pdb) pkg_resources.get_distribution('paramiko').version
'1.13.0'

Answer 1

1) Cron task to move folders from /home/user/Desktop to /var/www

2) Login as root. ( obvious security issues )

After running sudo passwd root on the host server I am now able to transfer files to /var/www with root.

I had also added user to www-data And recursively chowned the files and directories, but I think setting up a root password did the trick.

Edit dont do the above:

Change the permissions, and/or ownership

On linux: If you can ssh in:

ls -ld /path/to/location

to see who owns the directory and has r/w permissions.

bob@bob-p7-1298c:~$ ls -ld /var/www
drwxr-xr-x 3 root root 4096 Sep 24 10:39 /var/www

Then look into using:

• usermod
• addgroup
• useradd
• chown
• chmod

to give the user r/w permissions.

This can be done by:

• changing who owns the directory
• adding a user to the group of the directory
• creating a new group and changing the group on the directory
• changing the owner
• Changing the r/w permissions of owner,group, or public.

Answer 2

I had the same error for sftp.get

I tried to do:

sftp.get('/remote_server/readme.txt', localpath='C:\\Users\\user1\\Desktop')

Got the error above: [Errno 13] Permission denied

The fix is that we need to specify the whole path include the file name.

sftp.get('/remote_server/readme.txt', localpath='C:\\Users\\user1\\Desktop\\readme.txt')

Answer 3

I was getting the "permission denied" error on Windows myself. My code looked like this -

sftp.put(sftp_local_path + "\\filename.txt", sftp_remote_path)

Then I changed it like below -

with pysftp.Connection(host=sftp_host,username=sftp_user_id, password=sftp_pwd, port=sftp_port, cnopts=cnopts ) as sftp:
    with sftp.cd(sftp_remote_path):
        sftp.put(sftp_local_path + "\\filename.txt")

and I was able to upload the file successfully.

Answer 4

I had the same error with a very similar traceback when using pysftp to put() a file. It turned out I was trying to put() a file that had the same filename as a file that already existed in that sftp directory. Changing the filename before put() fixed this for me.
