Ich habe mongo auf machine1 installiert Ubuntu 14.04.3 LTS server) in meinem lokalen Netzwerk. Ich habe auch den port @ geöffn27017 wie in @ erwähDie Anleitung mit folgenden Befehlen:

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

Aktuelle Regeln sind 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

Aber ich kann von Maschine2 (im selben Netzwerk) keine Verbindung zu diesem Port herstellen:

$ 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

    at connect (src/mongo/shell/mongo.js:181:14)
    at (connect):1:6 at src/mongo/shell/mongo.js:181
exception: connect failed

Ich habe auch versucht zu überprüfen, ob der Port geöffnet ist oder nicht:

$ nc -v 192.168.0.108 27017
nc: connectx to 192.168.0.108 port 27017 (tcp) failed: Connection refused

Ich bin nicht sicher, was ich vermisse. Muss ein dummer Fehler sein, als ich zum ersten Mal Mongo aufbaue. Bitte helfen.

Update (für die in den aktuellen Antworten aufgeworfenen Zweifel)

Yeah es läuft. Ich kann mich mit mongo von derselben Maschine verbinden, aber nicht von der anderen Maschine. Der Daemon läuft:$ service mongod status mongod start/running, process 31205 und der Hafen ist 27017$ sudo netstat -tulpn |grep 27017 tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 31205/mongodIch habe das @ geändebind_ip zu0.0.0.0 und mongo neu gestartet. Immer noch kommt der selbe Fehler.
