File transfer with python

[Valentin de Pablo Fouce]

Hi there,

I hope this is the rigth place, if not please, tell me which is the
right dicussion place. I apologize in such case.

Ok, I am trying to do a very quick application (is "home based" so is
not a big deal...). My intention is to transfer files from one
computer to another.

I am using several OS (Linux and Windows basicly, but potentially in
the future Mac too), and the computers won't be potentially in the
same network (ok, the most times will... but there will be
exceptions).

My intention is to be able to transfer files from one computer to
another in this environment.

Looking (and surfing) at internet the only suggestion given is to use
low level sockets for this file transfer. Is there another way to do
it, is there any top level library that helps you to do that?

That's a lot!

Have a look at Paramiko. It lets you do secure transfers easily (scp/sftp)

Do you have a USB flashdrive?

Networked file system (e.g. Samba/SMB), File Transfer Protocol (FTP),
whatever works for you. pysamba is available from sourceforge and there
is ftplib in the standard library. For most purposes though, you could
just setup a network shared directory and drag and drop files from the
file manager.

Python standard library offers tools for HTTP communication (rather easy
to use) -- see:
http://docs.python.org/library/simplehttpserver.html
http://docs.python.org/library/cgihttpserver.html
http://docs.python.org/library/basehttpserver.html
-- as well as:
http://docs.python.org/library/urllib.html
http://docs.python.org/library/urllib2.html

cygwin + scp or rsync are other options.

Well there's several file transfer protocols you could use, TFTP, FTP,
SFTP and you can do SCP and Rysnc over SSH.

AFAIK there's python libs that handle all of those. Unless you need very
high performance I'd suggest using SFTP (Secure file transfer protocol).

Lookup the Paramiko library, it does this and other SSH based stuff.

If your computers are distributed across many networks, and they all
have internet access, Richard Jones' GmailFS[1] might give you some
ideas. It uses the Python bindings for FUSE to create a local
filestore that's a wrapper around the Gmail API, stashing the actual
data on Google's servers. It's out of date now, but it shouldn't be
much of an effort to update to the latest Gmail API, or to replace
with any other backend data store you like. Google App Engine[2]
provides a hefty amount of free storage to developers, so that's
another option.

Your solution looks quite nice...but one question, just by looking to
it I think I will need to create an HTTP server on a "file" server PC,
isn't it?

Yes, in case of such communication protocols like HTTP always one side
have a role of a serwer, and the other -- of a client. However, please
note that files can be both downloaded *from* serwer and uploaded *to*
serwer. You can also run *each* side both as a client *and* as a serwer
(though it's rather unnecessary...).
