I have installed mongo on machine1(Ubuntu 14.04.3 LTS server
) in my local network. I have also opened the port 27017
as mentioned in this guide using following commands:
sudo iptables -A INPUT -p tcp --destination-port 27017 -m state --state NEW,ESTABLISHED -j ACCEPT
sudo iptables -A OUTPUT -p tcp --source-port 27017 -m state --state ESTABLISHED -j ACCEPT
Current rules are (iptables -L
):
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:27017 state NEW,ESTABLISHED
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp spt:27017 state ESTABLISHED
But I am not able to connect to this port from machine2 (in the same network):
$ mongo --host 192.168.0.108
MongoDB shell version: 3.0.4
connecting to: 192.168.0.108:27017/test
2016-01-23T18:02:14.848+0530 W NETWORK Failed to connect to 192.168.0.108:27017, reason: errno:61 Connection refused

I also tried checking if port is opened or not:
$ nc -v 192.168.0.108 27017
nc: connectx to 192.168.0.108 port 27017 (tcp) failed: Connection refused
I am not sure what I am missing. Must be some silly mistake as I am setting up mongo for the first time. Pls help.
Update (for the doubts raised in current answers)
$ service mongod status mongod start/running, process 31205
and the port is 27017 $ sudo netstat -tulpn |grep 27017 tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 31205/mongod
bind_ip
to 0.0.0.0
and restarted mongo. Still the same error is coming.Mongo logs:

make sure that mongodb daemon is running, and listening on 0.0.0.0, but not 127.0.0.1 port
for example, for my local mongodb, it has this config:
[vodolaz095@steel ~]$ cat /etc/mongod.conf
##
### Basic Defaults
##
# Comma separated list of ip addresses to listen on (all local ips by default)
bind_ip = 127.0.0.1
# Specify port number (27017 by default)
#port = 27017
for mongodb server to listen for remote connections, you can change
# Comma separated list of ip addresses to listen on (all local ips by default)
bind_ip = 0.0.0.0
