Hi,
I will bump my own post from a month back (see below) and just will answer the
question in case anyone else was looking for something similar. I haven't found
a way to remotely navigate the file system through ParaView Python API objects,
but of course there are other Python packages which can achieve that. I used
paramiko. Below is my minimal example.
from paraview.simple import LegacyVTKReader, RenameSource, Connect
from paramiko import SSHClient, AutoAddPolicy
'''
This script extracts the output of a remote ls command with to feed into
a LegacyVTKReader. The main use is it to make a collection of VTK files
into a time sequence inside PV.
'''
# Inputs:
host = 'remote.host.com'
port = 22
username = 'me'
key_filename = '/path/to/private/key'
pvhost = 'localhost' # I typically run pvserver through an ssh tunnel so
pvport = 22227 # these are the parameters for local port forward
data_dir = '/path/to/data/on/remote'
# SSH part
# to get a list of files to open
client = SSHClient()
client.set_missing_host_key_policy(AutoAddPolicy())
client.connect(
host, port=port,
username=username,
key_filename=key_filename)
stdin, stdout, stderr = client.exec_command(
'ls -1 {0}'.format(data_dir))
lslines = stdout.readlines()
client.close()
# ParaView part
Connect('localhost', 22227)
reader = LegacyVTKReader(FileNames=[
'data/{0}'.format(l.strip()) for l in lslines])
RenameSource('source', reader)
Hope this helps someone!

Is there nothing they can't do?
