I recently updated my Ubuntu version in Vagrant from 12.xx to 14.04 and have also updated Guest Additions. I use VirtualBox and SSH into my development VM which primarily is used for Rails applications. The Rails server is listening on port 3000 which is also configured in the Vagrantfile as shown:
# config.vm.network "forwarded_port", guest: 3000, host: 3000
I have tried accessing 127.0.0.1:3000, localhost:3000, 10.0.2.2, tried using different ports, added exceptions to my Windows firewall, ran this:
iptables -I INPUT -p tcp --dport 1022 -j ACCEPT
I also tried different servers such as Unicorn and Thin in lieu of WEBrick rails server. I destroyed this VM and rebuilt/installed everything as well as upgraded to Ubuntu 14.04 yet again. I'm not sure why Windows won't display my stuff! Any ideas will be very appreciated. Thank you in advance. :-)

I am learning Dart. I already installed Dart, and also the CLI tools (webdev and stagehand).
I successfully made a Dart console app and ran it without any issues. Then I started a bare-bones web app project and I ran the app with the following command:
webdev serve
And it started to run the web app in localhost on port 8080:
Serving web on http://127.0.0.1:8080
I already changed the forwarded port to 8080 in the vagrant file like this:
config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"
But I still cannot access/view the Dart web app, so my best guest is that I am doing something wrong with the port forwarding. How can I access my Dart web app running in vagrant from the browser?
I am using an ubuntu box.
I recently have been having a problem with my AWS EC2 instances. The problem is that I cannot hit my Rails servers via public IP, but I can hit localhost and the server will respond.
Here's what I'm doing:
Create new EC2 instance (t2.micro, ubuntu free tier)
Security group has port 22, 80, 3000 open to everyone (0.0.0.0)
SSH to EC2 instance, install rails (I've been using this to install)
Start rails server after install, it's running on port 3000
run "wget localhost:3000" and it returns index.html, yay!
go to my web browser, type in EC2 instance public IP and port 3000 (IP:3000), says it can't connect :(
kill rails server, restart it on port 80, wget works but can't connect via public IP
as a sanity check, I install nginx and run it, and can see the nginx start page on port 80 via public IP... so confused...
So I'm thinking it has something to do with how I'm installing Rails, but I've tried methods other than using that install script but am encountering the same problem... I've even tried creating an entirely new AWS account just in case I screwed up the settings in my original account but haven't had any luck. I have previously been able to get rails running on EC2 instances just fine (in fact I have EC2 instances using the same security group running on my AWS account right now and can hit those public IPs just fine), but am now just banging my head against the wall... any help would be greatly appreciated!
EDIT: For now, I've configured nginx to hit my rails server.... at least that works for now... although I'm still curious why I can't hit my rails server directly...
Check if rails listens on 0.0.0.0 or 127.0.0.1, default is to listen only on localhost.
-b, --binding=IP Binds Rails to the specified IP.
Default: localhost
From the Ruby on Rails 4.2 Release Notes:
Due to a change in Rack, rails server now listens on localhost instead of 0.0.0.0 by default. This should have minimal impact on the standard development workflow as both http://127.0.0.1:3000 and http://localhost:3000 will continue to work as before on your own machine.
If you are using 'rails server' and want to use the default port 3000 then use below:
sudo rails server -b 0.0.0.0
it can be accessed as http://[public_ip]:3000.
If you want to use it as a URL without the port use the below to run the server:
sudo rails server -p 80 -b 0.0.0.0
You just access it as http://[public_ip].
I was running the rails server on default port 3000 on my AWS Ubuntu instance and had allowed this port in the security group, inbound section but still I was unable to access my application by using this.
http://public_ip:3000
I searched a lot and this answer helped me. Explaining the answer. We have to make firewall setting flexible so that our firewall allows port 3000.
You can use this command to check if this port is allowed on firewall or not.
$ sudo iptables -L | grep :3000
If you see nothing it means we have to allow it using this command.
$ sudo iptables -A INPUT -p tcp --dport 3000 -j ACCEPT
This worked for me to get my rails app access on port 3000.
Hello i am trying to access my Webrick rails server that i started on my ubuntu to my windows 7 pc locally. I checked on ifconfig in my virtual box and used the inet:10.0.2.15 when i run my rails server and also used port 80 like this:
rails server -b 10.0.2.15 -p 80
It didn't gave me an error in the terminal but when i try to go to 10.0.2.15 on my windows browser, it says it can't connect. I tried disabling the firewall in windows but still wont work. Thank you.
Choose another network type for your VM ubuntu. I suggest the Bridged Network. Reboot vm, it should obtain ip in same network as your windows host (example 192.168.0.XXX). Then you will be able reach your rails server from network At any port 80 or 3000.
Can you share your ubuntu with the vm, via the apache server too? is that started? In macs you have to enable web sharing (or something similar to that wording). ON ubuntu what happens when you do localhost:80... if i recall it should say it works! or something like that.
I have a rails application running on localhost:3000. I wish to access it from another computer on the same network. I feel like i've done this before with ease, but it's giving me some grief. I can ping the IP of the computer just fine, but hitting ip:3000 in the browser doesnt work. I tried launching rails s -b ipaddress as well, and no luck.
Suggestions?
After making sure your server side firewall is open to the incoming connection on high ports (this is normally true and the default port is 3000, so you probably don't have to do anything) you must also start the server like this:
rails server -b 0.0.0.0
which binds it to the universal address. It binds to localhost by default.
Using this method you don't have to bind to port 80, but you can like this:
rails server -b 0.0.0.0 -p 80
(If you're using rvm then you may need to use rvmsudo)
To make this change more permanent edit your config/boot.rb and add this:
require 'rails/commands/server'
module Rails
class Server
def default_options
super.merge(Host: '0.0.0.0', Port: 3000)
end
end
end
Then you should only have to use rails s
Source: https://stackoverflow.com/a/29562898/1795429
rails server -b 0.0.0.0 -p 8000
This worked for me. No firewall issues, and no need to give super user permissions.
Yes, this was a good answer in general:
rails server -b 0.0.0.0
If you use Ubuntu, you probably have to open the port in the firewall:
sudo ufw allow 3000
If your system is running in VirtualBox, you have to check your Network Settings.
In the case of network mode NAT you have to click to the extended options and there to Port Forwarding. Add a rule for TCP protocoll, host port 3000 (or any other), and guest port 3000.
Assuming Webrick starts without issue, this is 100% a firewall issue. You should provide some specifications, like what operating system your host is running and whether or not you have administrator privileges as far as controlling the firewall.
If you're on Linux and running the iptables firewall service, you need to add a rule to accept traffic over port 3000. It would look something like:
iptables -A INPUT -p tcp --dport 3000 -j ACCEPT
That command would be a one-time-only solution though, you'd need to extend your current iptables rules script to make it permanent every time your system boots or logs in.
If you're running Windows, depending on whether you're running XP or Vista/7, you'd need to do something similar. I'm going to assume you're in the Vista/7 environment, and you would just need to follow the steps provided through this guide http://windows.microsoft.com/en-US/windows7/Open-a-port-in-Windows-Firewall.
Try running the server on port 80 instead, your firewall is probably blocking port 3000.
I am using foreman to manage my Procfile-based application.
Adding -b 0.0.0.0 to my bundle exec rails s command in Procfile worked for me.
One reason is your ip is not bind to the rails server. You can bind the ip with -b command option.
Usage: rails server [mongrel, thin etc] [options]
-p, --port=port Runs Rails on the specified port.
Default: 3000
-b, --binding=IP Binds Rails to the specified IP.
Default: localhost
i am developing a facebook app and i am using for that facebooker plugin and webrick server.
i have configured correctly my router to froward ports to my machine for 2 ports (80 and 3000)
the apache server can be accessed from the net http://ip:80 amd the webrick server can http://ip:3000 ,
i dont understand why , please help me.
What IP address do you have WEBrick set to listen on? My guess is it could be set to “127.0.0.1” which would cause the problem you’re describing. If so, set it to “0.0.0.0” and see if that works. If you’re starting the server with script/server, you can specify the IP to bind to with the -b flag:
script/server webrick -b 0.0.0.0 -p 3000
You have to access it from another Network not in your network. Because your server is running on IP and your accessing machine is also connected to the same IP[because of port forwarding]. So it will not work in same network. You have to access it from different WAN IP Network.
