I'm trying to build a mongo replica set on my server, Centos 5.6, that would be setup from 5 VB holding Ubuntu 8.10 and mongodb. The main problem is i can't connect to mongo on virtual box.

The network is setup over NAT with forwarded ports.

I have my image of Ubuntu 8.1. Below the way I create a box

VBoxManage createvm --name "mongovb_03" --ostype Ubuntu --register
VBoxManage modifyvm "mongovb_03" --memory 2048 --acpi on --boot1 dvd --nic1 nat
VBoxManage modifyvm "mongovb_03" --pae on --cpus 2 
VBoxManage storagectl "mongovb_03" --name "SATA Controller" --add sata --controller IntelAhci
VBoxManage storageattach "mongovb_03" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium "ubuntu_8.vdi"

Than I forward port using vboxtool.

So now I can have access my vbox via ssh like that:

ssh -p 2023 localhost

I can also access my apache on localhost:8083 or munin on http://localhost:8083/munin/index.html

The problem is that I can't access mongo.

My mongo.conf

dbpath=/var/lib/mongodb

#where to log
logpath=/var/log/mongodb/mongodb.log

 logappend=true

 port=27017
 journal=true
 bind_ip=127.0.0.1

So when I try to connect to mongo I get:

mongo 127:0.0.1:27003
MongoDB shell version: 1.8.1
connecting to: 127:0.0.1:27003/test

Wed Sep 21 14:33:31 Error shell/mongo.js:81

Or:

Thanks for all the help, I'm really stuck here.

Check your mongodb.conf (on ubuntu: /etc/mongodb.conf, not sure where on CentOS) and see if:

bind_ip = 127.0.0.1

If so, comment that line with "#":

#bind_ip = 127.0.0.1

Note that this may have security repercussions.

I'm not sure what the issue is but this certainly sticks out at me

getaddrinfo("127:0.0.1")

Shouldn't that be 127.0.0.1?
