I installed mongodb in Ubuntu14.04 server

I was not able to connect to mongodb via "mongoimport", "mongodump", "mongostat", etc. It always show "no reachable server"

```
mongoimport --db test --collection restaurants --drop --file dataset.json
2015-08-25T13:08:29.802+0800    [........................] test.restaurants 0.0 B/11.3 MB (0.0%)
2015-08-25T13:08:30.306+0800    Failed: error connecting to db server: no reachable servers
2015-08-25T13:08:30.306+0800    imported 0 documents

```

Somehow, I was able to connect with mongo shell

```
mongo --port 27017
MongoDB shell version: 3.0.6
connecting to: 127.0.0.1:27017/test

```

At first, I doubt if it cause by my iptables, so I flush all iptables rules and create rules for ALL accept, but it still same

```
 sudo iptables -S
    -P INPUT ACCEPT
    -P FORWARD ACCEPT
    -P OUTPUT ACCEPT
    -A INPUT -j ACCEPT
    -A INPUT -i lo -j ACCEPT
    -A FORWARD -j ACCEPT
    -A OUTPUT -j ACCEPT
    -A OUTPUT -o lo -j ACCEPT

```

I search the stackOverflow and google and someone told marked off 
bind\_ip or set bind\_ip to 0.0.0.0, I tried all but still failed.

Below are my mangodb config, would any one can help me to check?
Thanks for your help
