Difficulty accessing local webserver

Question

I have an Echoprint local webserver (uses tokyotyrant, python, solr) set up on a Linux virtual machine.

I can access it through the browser or curl in the virtual machine using http//localhost:8080 and in the non-virtual machine (couldn't find out how to say it better) I use the IP on the virtual machine also with the 8080 port.

However, when I try to access it through my android on the same wifi I get a connection refused error.

If you are referring your localhost on your system from the Android emulator then you have to use 10.0.2.2:8080. Because Android emulator runs inside a Virtual Machine(QEMU) therefore here 127.0.0.1 or localhost will be emulator's own loopback address.

I don't know if it makes a difference or not but I'm using an actual android device. I have already tried to use that address and I still get the connection refused error. Could it be that the ports are closed even if I'm doing everything in the same wifi? – RicardoDeus Jul 03 '14 at 15:32

Is the server bound to localhost or 0.0.0.0?

Maybe your host resolves that ip to some kind of a localhost as well, due to bridging.

The server is bound to 0.0.0.0. Out of the virtual machine I use 192.168. etc. I am not sure if I should be using this address in other devices though. – RicardoDeus Jul 03 '14 at 15:34
What type of networking do you use for the VM? Is it bridged networking? – little_endian Jul 03 '14 at 15:43
It is NAT. Should I be using bridged? – RicardoDeus Jul 03 '14 at 15:44
Not 100% sure, but give it a try; might be the problem. As you asked for a "hint" and not a "solution" I was like "mh, give it a try" :) – little_endian Jul 03 '14 at 15:47
Tried bridged and I can't get a connection :P thanks for trying to help. I'm using VMware Player btw – RicardoDeus Jul 03 '14 at 15:56

Both "localhost" and "127.0.0.1" are local loopback interfaces only: they only make sense within the same machine. From your Android device, assuming it's on the same wifi network as your machine, you'll need to use the actual IP address of your main machine: you can either find that from the network settings of that machine, or from your router's web interface.

I have tried to use the IP you can get from sites like "whatismyip" with no success. – RicardoDeus Jul 03 '14 at 16:00
No, not that: those sites will report the external address of your network, but your machines will be behind NAT so you need to find the local network addresses. Probably something like 192.168.1.1, or 10.0.0.1. – Daniel Roseman Jul 03 '14 at 16:27
Oh. I already tried that too and I got connection refused. Is it possible that the ports are closed even if I am working on the same wifi? – RicardoDeus Jul 03 '14 at 16:42
Blame your firewall. Switch it off. – greenapps Jul 03 '14 at 17:33
Tried that and it still didn't work.. Don't know what else to do :( – RicardoDeus Jul 04 '14 at 08:51

In case someone has the same problem, I solved it. The connection has to be by cable and on the VMware Player settings the network connection has to be bridged, also you must click "Configure adapters" and uncheck the "VirtualBox Host-Only Ethernet Adapter".
