Authentication Problems when connecting with new created user (Lab: Change The Default DB Path)

MongoDB University M103: Basic Cluster Administration
#1

I am having trouble with authentication and I am receiving these errors when attempting to submit the assignment. It seems I’m able to authenticate to the admin database after connecting to port 27000. When trying to connect, and authenticate at the same time my created user does not seem to be recognized. I’ve been at this for hours. Could someone please help me figure this out?

"Client experienced a timeout when connecting to the database - check that mongod is running on the correct port, and that your user was created with the correct settings.
"

Here is what is outputted from the mongo console after authenticating:

connecting to: mongodb://127.0.0.1:27000/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("257bbc18-0e9e-46da-9d94-dcfd174edaea") }
MongoDB server version: 3.6.17
MongoDB Enterprise > use admin
switched to db admin
MongoDB Enterprise > db.auth("m103-user", "m103-pass")

And this is outputed from the mongod after trying to submit the assignment

You’ll get appropriate responses if your thread is linked to right course and chapter. Suggest you fix this and also mention the title of the lab that you’re working on.

Thanks for the response. My mistake, I’ll fix that.

#4

Check that you’ve met this requirement:

I.e. you can connect to 192.168.103.100 on the admin db

#5

Thanks for the reply. I have specified that ip. I’m still receiving the error. This is my config file:

net:

  port: 27000

  bindIp: "192.168.103.100,127.0.0.1"

security: 

  authorization: "enabled"

storage: 

  dbPath: "/var/mongodb/db"
#6

Can you connect?

PS: Suggest you specify localhost first. You’ll need to shutdown and restart the mongod.

#7

How do I go about doing that? I’ve already reset the session. I’ll try setting local host first

#8

Are you sure you are starting mongod correctly.

#9

I am using th following flag to start the mongod
mongod --config /shared/config/config.conf

#10

mongo --host 192.168.103.100:27000 ...other options

Refer to the mongo documentation to learn more.

Hello the issue was resolved. Sorry for the late response. I apparently have a cap on the number of responses I can make on a given post.
