Open file on remote linux server

[The Bear]

Hi I'm looking to do something like this

f = f.openfileobj(remotefileloc, localfilelikeobj)

my remote files are on a solaris box that i can access using ssh (could
prehap request othe protocols if necessary)

anyone got any ideas?

many thanks

Charlie

I don't know of any Python library that will give you that kind of
access to a remote file over ssh. It sounds like a fun project
though!

If nothing else, you can install the ssh filesystem for Fuse, and just
mount the remote filesystem as if it was local.

try paramiko. Or just use subprocess to scp and open the file locally.

You could look into GIO which is a virtual file system API used in
GTK+. I was a bit put off by it (necessarily) exposing the asynchronous
nature of remote file operations. Its fun to write a small amount of
asynchronous file I/O code but ensuring that all of your code handles
all the potential problems with remote connections is tedious.

Base library:
http://library.gnome.org/devel/gio/stable/

Python bindings:
http://library.gnome.org/devel/pygobject/stable/

Before committing to this, you should double check that these are the
currently supported APIs. There was an earlier API GnomeVFS that has
been deprecated for several years now and I don't follow this area closely.

try paramiko. Or just use subprocess to scp and open the file locally.

import paramiko

ssh = paramiko.SSHClient()
ssh.load_system_host_keys(os.environ['HOME'] + '/.ssh/known_hosts')
ssh.connect('localhost')
try:
ftp = ssh.open_sftp()
# To write
fh = ftp.file('/tmp/foo.test', 'w')
fh.write('This is a test string\nAnd this is another one')
fh.close()
# To read
fh = ftp.file('/tmp/foo.test', 'r')
for l in fh:
print l,
fh.close()
finally:
ssh.close()

You may need to add some password handling in there (for me my
environment takes care of that).
