import paramiko
from socket import error as socket_error
import os 
server =['10.10.0.1','10.10.0.2']
path='/home/test/'
for hostname in server:
    try:
        ssh_remote =paramiko.SSHClient()
        ssh_remote.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        privatekeyfile = os.path.expanduser('~/.ssh/id')
        mykey = paramiko.RSAKey.from_private_key_file(privatekeyfile, password='test123')
        ssh_remote.connect(hostname, username = 'test1', pkey = mykey)
        sftp=ssh_remote.open_sftp()
        for i in sftp.listdir(path):
            info = sftp.stat(i)
            print info.st_size      
    except paramiko.SSHException as sshException:
        print "Unable to establish SSH connection:{0}".format(hostname)
    except socket_error as socket_err:
        print "Unable to connect connection refused"

This is my code. I tried to get file size of remote server files. But below error was throwing. Can some please guide on this?

Error

SFTPClient.listdir returns file names only, not a full path. So to use the filename in another API, you have to add a path:

for i in sftp.listdir(path):
    info = sftp.stat(path + "/" + i)
    print info.st_size

Though that's inefficient. Paramiko knows the size already, you are just throwing the information away by using SFTPClient.listdir instead of SFTPClient.listdir_attr (listdir calls listdir_attr internally).

for i in sftp.listdir_attr(path):
    print i.st_size
