Bug Description

Hi,

I am uploading zip files to a linux server from xp
some time there is no error, some times it can not upload a specific file.

the test program:

    transport = paramiko.Transport((host, port))
    transport.connect(username = username, password = password)
    sftp = paramiko.SFTPClient.from_transport(transport)

    localpath = 'C:/Program Files/infoio/mklogger/zlog/20091203173444.zip'
    filepath= '/home/amit/tmp/server/uploadedziplogs/zlog/20091203173444.zip'

    sftp.put( localpath,filepath)

    sftp.close()
    transport.close()

the out put:

Traceback (most recent call last):

It's happening for me now too. I'm on Python 2.6 on a Mac client, uploading to a CentOS machine.

I'm using paramiko 1.7.6 with pycrypto 2.0.1 on Mac 10.6 and putting on a CentOS machine.

May be a red herring... it may just be a problem with authentication.

Once I double checked my credentials, and changed my
   ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
to
   ssh.load_system_host_keys()

I could upload to the server.

Hello,
I have similar error and I was wondering where in the code should I place this load_system_host_keys()?

I am using this simple to use ssh.py below.

http://media.commandline.org.uk/code/ssh.txt

And in my code I'm just doing:
import ssh
s=ssh.Connection(host=....,usernanme=....,password=....,port=...)
s.put(..file1...)
s.put(..file2)
s.put(...file3)
s.close()

Could somebody point to a proper place/line in the ssh.py code?

This is the error I'm trying to fix.
 File "./upload.py", line 31, in <module>

    s.put('/home/lucas/tmp/sql_report_server/eft_files/%sxxxxx' %date2import)

I've done some research on this and verified that the reason for this error is because the call to sftp.stat() fails. This is most likely because the SFTP server doesn't not support the df -hi command.

If you login to the remote machine from the command line and type.

sftp> df -hi .

You'll most likely get something like:

Server does not support <email address hidden> extension

Perhaps there is another method to determine file stats via sftp?

I have the same problem as Lance.
I need to put a file on a remote server that does NOT support "df -hi ."

Is there a solution for this?
Perhaps just have sftp.put NOT verify the filesize with self.stat?

Alan Rotman (alan-actcom) wrote :

Is it a reasonable solution to just comment out the stat at the end of put in sftp_client.py?
Since the sftp server does not support stat, ...

        #s = self.stat(remotepath)
        #if s.st_size != size:
        # raise IOError('size mismatch in put! %d != %d' % (s.st_size, size))
        #return s

Greetings,

I have found a solution to a similar issue.

This fails:

srv = pysftp.Connection(~)
srv.put(localPath,remotePath)

This works:

srv = pysftp.Connection(~)
srv.chdir(remotePath)
srv.put(localPath)

Not sure how useful this is, but it worked for me.
