Can you please assist. I am doing some channeling from my windows machine via python. I could not get into the remote desktop. I am using ssh, but I know this seems to be wrong. This is working to jumpbox which is linux based.
My machine(windows) > remote desktop(VM machine) > network device via ssh
CODE:
for device in devices:
device = device.rstrip()
#for jump in jumphost_devices:
print("Connecting to Device %s..." % (device),)
jhost = paramiko.SSHClient()
jhost.set_missing_host_key_policy(paramiko.AutoAddPolicy())
jhost.connect('10.10.10.11', username=username, password=password, timeout=10)
vmtransport = jhost.get_transport()
dest_addr = (device, 22)
local_addr = ('10.10.10.11', 22)
vmchannel = vmtransport.open_channel("direct-tcpip", dest_addr, local_addr)
#
host = paramiko.SSHClient()
host.set_missing_host_key_policy(paramiko.AutoAddPolicy())
host.connect(device, username=username, password=password, sock=vmchannel, timeout=10)

thanks,
I am attempting to connect to one of our SFTP servers in order to automate a report. We pull a file from this server once a week and I am not able to get this connections to work. I am not finding any useful references to the below traceback error. Anyone have an idea of what could be causing this problem?
I get a socket.timeout error after 2 or 3 seconds of executing the code.
import paramiko
cli = paramiko.SSHClient()
cli.set_missing_host_key_policy(paramiko.AutoAddPolicy())
cli.connect(hostname='AHOST', port=21, username="USER", password="PASS")
stdin_, stdout_, stderr_ = cli.exec_command("ls -l ~")
print(stdout_.readlines())
cli.close()

You are connecting to FTP port 21.
SSH/SFTP uses port 22 (what is the default value of the port parameter, which you override).
Side note 1: Your question is about SFTP. Yet, instead of using SFTPClient, you use SSHClient and execute shell commands – That has nothing to do with SFTP.
Side note 2: Do not use AutoAddPolicy like this. You
lose security by doing so.
See Paramiko "Unknown Server".
I am new to neo4j world. I have successfully used it on my macbook. Now I am deploying it on a remote Linux machine with the same setup. But I keep getting this Protocol error. What caused this issue? How to fix this? I have been banging my head on this error for days.

Seems to be port issue. Is the bolt port open or not? You have access to the port or not?
Check the output of the following command:
lsof -i tcp:7687
change the port number if you have changed bolt port address.
It turns out it was because I used the wrong credentials for this connection.
I'm trying to get a connection established to a FTP server with SSL from within Python (v3.3.0). But I keep getting a timeout. I am NOT using port 990 as the SSL port (paranoid). Would that be the cause of this problem? And if so, how do I specify the port I am using?
Here's my script:
from ftplib import FTP
from ftplib import FTP_TLS
ftps = FTP_TLS('ip address')
ftps.auth()
ftps.sendcmd('USER uname')
ftps.sendcmd('PASS password')
ftps.prot_p()
ftps.retrlines('LIST')
ftps.close()
And here is the result:
Traceback (most recent call last):
File "Scrpit name removed for posting", line 12, in <module>

sock.connect(sa)
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
any advice would be greatly appreciated,
After looking at the ftplib source, it doesn't seem to want to use any port but 21.
I think you should be able to work around this, something like
import ftplib
ftplib.FTP.port = 995 # or whatever port you are using
ftps = ftplib.FTP_TLS('hostname', 'user', 'pwd')
ftps.retrlines('LIST')
Set the port through the connect
import ftplib
ftps = ftplib.FTP_TLS()
ftps.connect ('hostname', 991)
The next script runs fine on my mac. When I try to run it on my WebHosting (bluehost) I'm getting socket.error: [Errno 101] Network is unreachable. Any idea how can I fix it?

Their support isn't helpful at all.
Can it be port related or maybe SSL?
On bluehosts help pages they mention that outgoing connnections are restricted, so ther problem isn't with your program. The only way of getting outbound connections to be allowed seems to pay for it.
