paramiko sftp erro denied

I got this code, it encrypt the file passwords.txt and send to my kali linux machine:
...snippet....
host = '192.168.15.18'
user = 'kali'
passwd = 'kali'
path = '/home/kali/password'
# sending Descrypt
#creating object SSHClient
try:
ssh = paramiko.SSHClient()
#credentials
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
socket.gethostbyname(host)
ssh.connect(hostname=host, username=user, password=passwd)
pass
except:
print("Fail.")
exit()
#Criando um canal de conexão
sftp = ssh.open_sftp()
print('Sending passowrd and decryptor.py')
#Sending password e decrpyter to host
sftp.put("decryptor.py", f"{path}/decryptor.py")
sftp.put("password_crypto.txt", f"{path}/password_crypto.txt")
#closing
sftp.close()
But i got this error:

My code was working 1 month ago. The encrpyt and desccrypt works, but it not sending to my host...
Someone knows what can i do?

Copying a file from a server

I am currently trying to copy a file from a server to a local file. Below is my current code. I am currently generating the following error, [Errno 13] Permission denied. I believe this is associated with the remote path. Any ideas?
import os
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname='de.ac.uk', username="hfseb", password="kjsvbkjcb")
sftp = ssh.open_sftp()
localpath = '/Users/abc/def'
remotepath = '/home/abc/def/game.log'
sftp.put(localpath, remotepath)
sftp.close()
ssh.close()
Error generated

Probably the remote def directory have wrong permissions.

Unable to download file with pysftp get

I am able to connect the sftp with pysftp successfully, but getting error while downloading file as FileNotFoundError: [Errno 2] No such file. I also observed that the file is just creating at local path adding '?' along with extension. Below are more details.

Just add "/" in front of ftpsource. i.e. "/2020/Jan/10/". It should work

FTP not running on PC

I was trying this FTP file transfer code. The thing is that when I had run this code on an online environment(a workspace that I created on Cloud 9) then it worked fine and uploaded the file but when I run this on my PC I get an ERROR. How can I resolve it?
from ftplib import FTP
ftp=FTP('**domain**')
ftp.login(user='username',passwd='password')
ftp.cwd('/')

filename='fileName.txt'
localfile=open(filename, 'wb')
ftp.retrbinary('RETR '+filename, localfile.write, 1024)
ftp.quit()
localfile.close()
def placeFile():
filename= 'Strinzy.txt'
ftp.storbinary('STOR '+filename, open(filename,'rb'))
ftp.quit()
placeFile()

If you are using vsftpd then make sure your vsftpd service is running in your machine and /etc/vsftpd.userlist has username in it.

python mrjob - gaierror: [Errno -2] Name or service not known

I'm trying to access s3 files from the mrjob module.
Here's the code that's failing:
from mrjob.emr import S3Filesystem
fs = S3Filesystem("<aws_access_key_id>", "<aws_secret_access_key>", "us-west-2")
fs.get_s3_key("s3n://<bucket>/<folder>/file.txt")
(but with the actual aws_access_key_id, aws_secret_access_key, bucket, and folder) and the error I'm getting is:
Traceback (most recent call last):
File "<input>", line 1, in <module>

Any suggestions?
Thanks!

This (s3n://)
fs.get_s3_key("s3n://<bucket>/<folder>/file.txt")
should be this (s3://) :
fs.get_s3_key("s3://<bucket>/<folder>/file.txt")
