Problem connecting to localhost:3000

[Gaba Luschi]

Hi,
After typing "rails server", I tried to go to http://localhost:3000, as
well as http://0.0.0.0:3000, but I got an error message. In the first
case, I get: Connection refused. For the second one, there was an error
about no DNS entry?
Help!

Please paste in what you see in Terminal after you typed this. You
might also see some sort of traffic log from the first try (the one
that was refused). Also, what does your /etc/hosts file look like? Do
you have the Firewall up? (not sure that matters on localhost, but
worth a try)

Walter,
This is what I get when I type in "rails server"

=> Booting WEBrick
=> Rails 3.0.4 application starting in development on
http://0.0.0.0:3000
=> call with -d to detach
=> Ctrl-C to shutdown server

How do i check to see what my etc/hosts file look like? It's in a demo
app, in views, with a basic index.html. How do I check re: firewall?
Thanks!

If you're using a Mac, and TextMate, type mate /etc/hosts in your
Terminal. If you don't have TextMate, you can use your favorite
command-line editor through the generic (alias) command edit, as in
edit /etc/hosts. Or nano /etc/hosts for that very easy-to-use editor.

Again, on the Mac, the firewall is configured in the System
Preferences app, in the Security section.

On other platforms, I can't say for sure about either of these. On
anything Unix-like, edit /etc/hosts should get you **something**.

I have windows. When I type in "edit /etc/hosts", I get
MS-DOS Editor

Is there something in particular I should look for here? I get
/B - Forces monochrome mode
/H - Displays the maximum number of lines possible for your hardware

Doesn't the last part of that line indicate Windows?

So...how can I get http://localhost:3000 to display? Or connect to the
host, given that it seems like when I type "rails server" i get the
standard booting webrick messages...?

Did you check the windows firewall (or any other firewall you may have installed)? Worth tryin 127.0.0.1:3000 as well, I've occasionally had localhost resolve to an ipv6 address somehow

On Windows XP your hosts file is located at C:\Windows\system32\drivers\etc\hosts. Run the following and let us know what is in it.

edit C:\Windows\system32\drivers\etc\hosts

That's what I get.

thanks!

This is good. Next thing is to turn off your Windows Firewall. It's under Control Panel->Windows Firewall.

That's what I get.

thanks!

Look in your system tray for it. You can also check your Add & remove Programs list.

I am building my environment on my Mac / Yosemite

Here is my /etc/hosts file

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost

I have installed Ruby, Ruby on Rails, mysql2, homebrew, gems (bundled),
built the newapp, run all the updates. Tried: localhost, 127.0.0.1,
ports 3000, 4000, 4040, 5000, 5050

I don't get it. What is the issue with connecting to the rails server?

If there is a concise answer to resolve this issue, I have not found it
yet.

Thanks,

bfulbright

What server are you using, and how are you trying to start it?

If it fails to start there should be some kind of error message.
