I'm following this guide here https://github.com/flaree/Flare-Cogs/tree/master/dankmemer. I got to the import rethinkdb part but I get this error when running the r.connect('localhost', 28015).repl()
command. Been searching yesterday for a fix but couldn't find one.
r.connect('localhost', 28015).repl()

You need to run rethinkdb first.
Enter your venv, and run tmux. Then run rethinkdb inside your tmux shell. This starts the rethinkdb server, and keeps it running. Close the SSH session, and open another one. Try running your code again.

I was running a server within a docker container, the package and image were provided by others so I can't access the code but only the tar.gz package, and I have no idea what services this container is providing.
It worked right several days ago and was not working since one restart, then I restarted it several times trying to get it to run, but it still has the same error. Is there any chance to make it run without touching the code since I cannot? Here is the error description:

I have written a script which gets data from a sqlite db to upload into MySQL db. The structure of the code is as below.
def insert_to_mysql(_row):
# get mysql connection by Pymysql
connection = pymysql.connect(..., connect_timeout=31536000)
# insert data
connection.close
def get_data_from_sqlite(_db):
for i in sqlite_generator:
insert_to_mysql(i)
the code works fine. But the connection get's time out without certain pattern with the below trace back very often, despite the connect_timeout in connection object and I am using one object per row. My logic is to create one object for a row so that there will not be timeout issue.
Can anyone help me in understanding what's going wrong here?

I first followed the tutorial on the heroku site. I did this
pip install rq
then in a worker.py file
import os
import redis
from rq import Worker, Queue, Connection
listen = ['high', 'default', 'low']
redis_url = os.getenv('REDISTOGO_URL', 'redis://localhost:6379')
conn = redis.from_url(redis_url)
if __name__ == '__main__':
with Connection(conn):
worker = Worker(map(Queue, listen))
worker.work()
and then
python worker.py
and I got the following error

I then went to google and found the package index which I also followed which is

>>> r.set('foo', 'bar')
hit enter and got the following message

I have done no more or less then what these tutorials ask. How can I make this work?
You need to run the redis server. Type redis-server on you console to start the server(Mac OSX).
$redis-server
Remember that the worker needs a broker(redis) in order to communicate with your app.
I trying to get validate_email package (https://pypi.python.org/pypi/validate_email) to verify an email for me on a Windows 7/Python 2.7 device. The following works:
>>> validate_email('example#example.com')
True
>>> validate_email('example#example.com',check_mx=True)
True
>>> validate_email('example#example.com',verify=True)
True
But when I try a commercial email server example to check if the host has SMPT Server and/or the email really exists, it fails as follows:
>>> validate_email('example#gmail.com')
True
>>> validate_email('example#gmail.com',check_mx=True)

It appears that I'm trying to access a port that I don't have permission to, but I don't know how to change to a port that would work and has the correct permissions.
Any suggestions?
It looks like this could be a problem with Windows Firewall blocking access to certain ports.

I'm running a Mac OS X and used postfix to enable localhost.
This is the error message I get:

Use netstat to verify that a SMTP server is bound to port 25 of an appropriate interface in the first place.
Check the postfix log file, which might be at /var/log/mail or something similar, depending on how you installed postfix.
