Set up a simple go server in a webhost - go

I wanted to set up a simple go server in a webhost. I acquired a domain mydomain.com and hosted it using Bluehost. Now, going through the Go tutorial, I went through this example http://tour.golang.org/#59 and it works fine on my machine. Now, instead, I want to make the HelloWorldServer work when I call mydomain.com:4000 or some other port.
What I did was ssh to my server at bluehost, install go there, then compile the server and run. But then I try to access mydomain.com:4000 and it is not found. I also tried to change "localhost:4000" to just ":4000". any ideas how to make it work ?
Any help or pointers are appreciated. (some more details: it is a shared-hosting account)

This is due to the firewall on your BlueHost server not having ports (including 4000) open on a shared hosting account, Firewall Port Restrictions
If you want to do some simple (and not so simple) web hosting, why don't you look at Google App Engine

Is it possible to install localhost server in one pc and to access on multiple computers on a same network.?

We are building php web application while i am a designers and my friend is developer we work on different pcs we want to test the file by runnig on localhost on both of our pc how can we reach it. I have gone through some of concepts in internet but didn't get proper info.
Yes. You need to create a firewall rule to allow access through whatever port you are serving on, probably 8080.
Here is how to create an inbound port rule in windows
Then they should be able to access your server by simply using your ip

create php web service and access to the internet

I have recently installed PHP, MySQL Server, and Apache web server. I played around with some PHP scripts locally on the PC to insert some entries to MySQL Database.
Noob question so please be patient with me:
How do I get my web service out to the internet, by self hosting? Say I already have a domain for example mydomain.com How do I make it so that when someone not within my network can access mydomain.com/something and can send some data so my server gets it and do anything with that data?
Webhosting
You have to have some form of webhosting. You pay for hosting and you can upload your PHP files to their servers. They will usually also have database servers you can use.
Your domain name has to point to those servers via DNS so the internet can reach your application. I'd suggest you search the internet for popular hosts that provide the tools your need for this.
Self hosting
Another possibility is to open your network up to the world, but this is not recommended unless you have network administration experience due the security trouble that comes with it.
In short: forward a port through your router to the machine running your application. The website portforward.com has instructions on how to do this but keep in mind that misconfiguration could lead to vulnerabilities in your network.
In order to make you site public
1. you need host
2. you need domain
there are bunch of hosting sites you should get one first.
This link explains very well about self hosting

Self Hosted WebApi Accessible over LAN

Very new to the Self Host WebApi, but I am very impressed with its ease of use and extendability. At least through this tutorial. Everything I've done so far works on my development machine whether I use localhost, 127.0.0.1, or my LAN Ip (192.168.0.x) but I am baffled why I can't access the service from any other computer even others in the same subnet.
In short after going through the tutorial on the machine where it is running:
Browsing to
localhost:3636/api/products/
results in the expected xml return.
On another machine on the LAN browsing to:
192.168.0.x:3636/api/products/
results in a timeout
Data points for those who might know how this all interacts:
1.) My dev machine(192.168.0.x, server, host whatever you want to call it) has IIS on it; I was so paranoid it was in the way that I stopped it via the Administration GUI
2.) I have reserved the URL/Port with the following command line executions:
>netsh http add urlacl url=http://+:3636/ user=DOMAIN\USER listen=yes delegate=yes
>netsh http add urlacl url=http://192.168.0.x:3636/ user=DOMAIN\USER listen=yes delegate=yes
2.b) I've tried both of those together and individually, and tried changing the user to "everyone" to no avail
3.) I have tried to change the code in the tutorial to set the
config.HostNameComparisonMode = HostNameComparisonMode.Exact //default is Strong Wildcard
4.) I can successfully ping and tracert to 192.168.0.x from other machines on the LAN
5.) A friend recommended I setup a TCPListener and ensure I could telnet to that to eliminate the firewall as a possibility. If that logic is sound, the firewall isn't the problem
EDIT: Thanks for your help, here's another data point that I believe confirms it's not a firewall issue. I previously posted this connection when behind a rather obtuse (at least to a non Certified guy like me) Juniper Firewall/Router. I have since redone the tutorial on another machine (without IIS) on my home network and still cannot publish the service to other computers within my LAN. Any ideas?
Well it wasn't the hardware firewall, it was the windows firewall! yikes i wasted a bunch of time on that. Once I turned off the windows firewall (the code runs in an intranet anyway) everything worked.
Anyone know of a good site that explains how firewalls and wireshark interact; or i suppose that just has to be one's first test.
I would try a couple things:
First off, get rid of the HostNameComparisonMode line. That might actually disable requests coming from other machines.
If things still don't work, try getting rid of the URL ACLs and run your application as an administrator and see if that works. If that works, you may be able to add the URL ACL back on and not have to run as an administrator. You should only need the one with '+' as the hostname.
I faced the same problem when i tried to self host using OWIN. What worked for me was -
Run Visual Studio as an Admin
Remove any and all netsh urlacl port registrations that I had added while debugging this issue
Add a inbound rule to my windows firewall
I followed the instructions on this link
https://learn.microsoft.com/en-us/dotnet/framework/wcf/samples/firewall-instructions
Check out the section - To enable a port range in advance
That's it! I was able to call my api from other computers on the network.
Hope this helps...

IIS 7 and ASP.Net MVC issue

This is a bit complex - so here we go.
I am developing a mobile web application using asp.net mvc and I need to test it locally on my iPhone. So far I have the first iteritaion of the site running on my local dev laptop. I created a virtual dir for the site under IIS 7 on the same machine. I deployed the site to that folder from VS2008. I open a browser and entered "" and the site cam up just fine. I am runnig a home network with locked down WIFI and both the laptip and my iPhone are on the network. So now I want to test with the iPhone but the site won't come up when browsing to "". I have another machine that is also on the network and I get this error message when attempting to browse to the site:
"Website (laptopname) is online but isn't responding to connection attempts"
I have a feeling that this has something to do with IIS setting and \ or application pools but have not been able to find anything relavent goolging. Any help appreciated.
There are some possibilities:
iPhone is not able to resolve your laptop by name. Try using the IP address of your computer in the URL instead.
The firewall on the laptop is blocking inbound connections from other machines. Check your firewall.
The IIS Website is configured with a host header localhost so it won't respond to requests to other hostnames. Check the binding for the Web site in the IIS Manager.
To eliminate possible network issues, you can create an ad hoc WiFi network on your PC and connect to that network to test.
Check that Allow Anonymous Access is set for the site
I suspect you are not alone, as I had this exact problem. I developed a small port opener I called "SharpProxy" that may make your local testing much easier.

My IP seems to be blocked by web hosting server

I have a strange problem, I just installed my php web site on a shared hosting, all services were working fine. But after configuring my app I just could visit my web site only once, other attempts gives:
"The server is taking too long to respond.".
But from other IP i can access, but only once, it seems all ip addressess beeing blocked after first visit(even ftp and other services get down, no access at all from the IP), can anyone help to explore this problem ? I don't think that it's my app problem, the app works fine on my local PC.
Thanks.
First thing to try would be a traceroute to determine where your traffic is being blocked.
In a windows command prompt:
tracert www.yoursharedhostingserver.com
At the moment, trying to access this address gives this:
Fatal error: Class 'mainController'
not found in
/home/myicms/public_html/core/application/crApplication.class.php
on line 181
I have tried it multiple times and it didn't block me. It might be that You have already solved this problem.
As far as I know, the behavior described by You could only be explained by a badly configured intelligent firewall. It may have been misconfigured by Your host.
If You visit a site at a certain host and suddenly You cannot access an ftp on this host, then it's either a (really bad) firewall or a (very mean) site that explicitly adds a firewall rule to ignore that address.
Some things that You might look into:
It might be something with identd too. What was the service You have configured on Your host? Was it by any chance any kind of server-controll panel (that might have an ability to controll a firewall)?
Is the blockade permanent, or does it go off after 24h, or does it only go off after rebooting the server? Does restarting some services makes the blockade go off?
Did You install any software that "protects Your server from portscanning"? It might be a bit too aggressive.
I wish You good luck in finding a source of this problem!
Chances are that if you can access it once that its actually working. The problem is more than likely in the php code than in the server.
