I install the sentry on my server with the Document，one-step，one-step，use my own postgresql，I just change the Database config
Finally,I invite myself by sent email,get this problem
Two possibilities
one：have some error in your config file，for instance your email password or smtp server and so on
two: you don't install smtp software，like postfix,sendmail and so on,and smtp is localhost in your config file

I am trying to connect to gmails's smtp server and send email. But unfortunately, I am getting the below error:
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
I have check the script in my local computer and it works. But it doesn't work on VPS. Using the below code to connect to server:
import smtplib, ssl
context = ssl.create_default_context()
with smtplib.SMTP_SSL("smtp.gmail.com", 465, context=context) as smtp_server:
smtp_server.login(username, password)
The Problem
I'm getting started with MongoDB on Python, I have a Ubuntu machine in my local network and MongoDB is installed there. When I try to connect with database using Python from Mac it throughs me an error. I searched about it and found out there is a .service called mongod.service that needs to be started along with mongodb.service. But when I try to start the mongod.service the it says the .service doesn't even exist. I tried both with IP and mongodb url, nothing works.
Ubuntu Terminal
$ sudo service mongod start
$ Failed to start mongod.service: Unit mongod.service not found.
$ sudo systemctl start mongod

Note That
I'm providing the correct username and password for the database.
I'm using a machine on my local network, which is not a live server.
I've also tried the following commands but they did not solve anything.
Ubuntu Terminal
$ mongod --auth --port 27017
$ mongod --port 27017
$ sudo rm /var/lib/mongodb/mongod.lock
$ sudo mongod --repair
For accessing mongodb from another machine in local network. You will need to check the following:
There is no firewall restriction in the server machine or client machine. In case there is a firewall, you will need to add rule exceptions to allow this port to be accessible. Both incoming and outgoing. (Ubuntu firewall)
You will have to add bindIp config to the mongodb config in server machine. Refer to docs here. You will need to add something like this:
net:
bindIp: 0.0.0.0
port: 27017
Make sure you are able to connect using this ip: 192.168.0.106(server in local network) from the server machine itself. This will make sure the server is listening in this ip.
$ Failed to start mongod.service: Unit mongod.service not found.
The solution for this error could be found here
The mongo atlas error might be due to the following reasons:
You will have to create an database user in order to connect to mongodb.
you can find it under the left panel -> Database access -> Add user
This will be because of a mismatch with username and password. In case you have any special characters in your password you will have to url encode them.
I have tried running the following:
import pymongo
from pymongo import MongoClient
client = MongoClient('mongodb://localhost:27017/')
db = client.test_database
collection = db.test_collection
collection.find_one()
but I get
ServerSelectionTimeoutError: localhost:27017: [Errno 111] Connection refused
Any suggestions on how to fix this? I am running this behind a corporate proxy, but have already set environment variables for that in .bashrc.
EDIT
If I run mongo from the terminal, I get
$ mongo
MongoDB shell version v4.0.13
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb

Its look like you didn't run any mongo instance on your machine
run the command mongod -f <config_file> and then test it again (this may needs a sudo permissions)
I thought I'd share this puzzler. . . I've been successfully using 'plain' paramiko for SFTP for years (but always to port 22). I had a requirement to do SFTP over a non-standard port (115) and I could not establish a connection.
Moving to pysftp solved the problem, but as best I can tell, pysftp is built ontop of the paramiko libraries.
'plain' paramiko code:
import paramiko
transport = paramiko.Transport((hostname,115))
transport.connect(username=user,password=passwd)
sftp = paramiko.SFTPClient.from_transport(transport)
The error thrown:
File "c:\python27\lib\site-packages\paramiko\transport.py", line 311, in __init__
'Unable to connect to %s: %s' % (hostname, reason))
paramiko.ssh_exception.SSHException: Unable to connect to XXX.XXX.XXX.XXX: [Errno 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
Moving to pysftp has solved the problem, but pysftp has a paramiko dependency
sftp = pysftp.Connection(hostname,username=user,password=passwd,port=115)
Insights are appreciated
I set up a Mosquitto server a few days ago using https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-the-mosquitto-mqtt-messaging-broker-on-debian-8.
Playing around with it, everything seemd to be working like I wanted. I am able to connect an android client and MQTTSpy to my own server.
Yesterday I had the great idea of looking for a Kodi plugin that would push status and info to MQTT: https://github.com/owagner/kodi2mqtt
It is able to find the server as I see changes in the Mosquitto log file, however I keep getting the same error:

From what I understand there are some issues with certificates but I am not 100% sure what is missing. In the other applications I do not need to provide my own certificates, so I don't see what is missing. I tried using the generated certificates in the Kodi addon, however they seem not to work and I get a different error:
1492541859: New connection from 81.240.134.64 on port 8883.

I'm not sure in what direction I should check. Is something wrong with my server/certificates (seems unlikely since other clients are working) or is something wrong with the python code of the Kodi addon? If so, could anyone shed some light on what is missing (I know my way around coding, just not really around certificate things).
Thanks for the help!

Your python client will need access to the trusted certificate authority. Copy the signed public certificate The browser clients don't need that because they already come loaded with trusted certificate authorities.
If the kodi addon is using the paho mqtt client library , then the following should fix it..
client.tls_set('$your server's public cert$.crt')
Try ssl connection:
openssl s_client -connect 81.240.134.xxx:8883 -CAfile /etc/certs/file.crt -debug
