I have uninstalled and reinstalled mongo (3.0.1), being sure i accepted the network access on windows 8, and yet i still have the same issue of \"waiting on 27017\".
I have a similar problem.
In my case when I ran MongoDb on docker with the following command and expected entering mongo shell to do some query but I got meesage 'waiting for connections on port 27017' and couldn't do anything.
docker run -p 27017:27017 --name mongo-container mongo
It seems that I was supposed to launch MongoDb on the background with -d option first and then use docker exec to enter the shell
docker run -p 27017:27017 --name mongo-container mongo -d
docker exec -it mongo-container mongo admin
