In Azure, I created a virtual network and then associated an Ubuntu Server virtual machine, created with Azure Resource Manager Deployment method, with the network. I then updated the associated Network Security Group and added an inbound security rule for port 80 (Source:Any, Destination:Any, Service:TCP/80). After installing Apache on the VM, I tried to access the server from my browser, but have run into a wall. I can SSH into the VM just fine, but web is a no-go, and I cannot figure out why. Any help would be appreciated.
It sometimes happen to me too because I forgot to RESTART the VM, yes just restart it. At least this works for me. and also dont forget to add outbound rule too
It worked for me with this inbound rule.
Note that when a VM is created from the portal (in ARM model), it gets automatically associated to a virtual network (vnet), a specific subnet within the vnet and a network security group.
When creating the inbound security rule, make sure to:
identify the correct network security group associated to the VM
use a priority number lower than 65500
set the source port range as *
You also need open port 80 on the VM to allow web access.
I dont think that creating your Network Security Group opens the desired port on the VM automatically.
By default in Azure Resource Manager (ARM), all ports are open; there is no need to make Network Security Groups (NSGs) to open ports, only to close them. Here is an example of an ARM template that deploys an ubuntu VM with apache:
https://github.com/Azure/azure-quickstart-templates/tree/master/apache2-on-ubuntu-vm
Alternatively, if you want an auto-scaling LAP stack using VM Scale Sets (in public preview), you can find the ARM template for that here:
https://github.com/Azure/azure-quickstart-templates/tree/master/201-vmss-lapstack-autoscale
Hope this helps! :)

Network Security Group
Azure VMs do not have any ports open firewall ports by default unless you open them when you provision your VM. When you created your Azure VM in the Azure Portal, you likely created a Network Security Group for the VM. If you didn't specify any ports to open during the VM's creation, you'll need to open up the VM's firewall.
To Open Ports
To open up the ports on the firewall, head out to the Azure Portal (where you set up the VM). Find the VM in the list of resources. It should take you to a page for your VM where the name, status, location, size, IP address, etc will be displayed. On the left side, you'll have a vertical menu > Select Networking. From there, you'll be able to see currently active firewall rules for the VM. Since you're likely missing HTTP (80) and HTTPS, select add inbound port rule. From the dropdown for service, select HTTP and assign a name/priority. Perform the same options, except this time selecting HTTPS (443). Press save and test. You should be able to access Apache running on the VM.
Additional Troubleshooting
The script you used may have inadvertently set up the VM's iptables. You can view Linux's firewall with sudo iptables -L to verify that no firewall rules have been enabled. Since Azure handles the firewall, you shouldn't need any iptables rules, but they could always be added for additional security.
This answer assumes that you do not have Azure's Load Balancing servers installed in front of the VM.
I have created a web application in glassfish and I can access it on my LAN.
How can I access the web application from a remote location over internet?
I do not have static IP.
Please reply.
Thanks.
Steps :
Creating virtual DNS(Domain name server) Server on your machine.
Port Forwarding.
Reference https://cookbook.fortinet.com/port-forwarding-60/
Remote Desktop Connection enabling.
Creating Inbound Rules. Reference :
https://www.howtogeek.com/112564/how-to-create-advanced-firewall-rules-in-the-windows-firewall/
Creating account on www.noip.com and create custom host and download DUC (Dynamic Update Client) Software.
Some more steps may have it depends on your LAN Router and firewall configuration.Use http://ifconfig.me/ to get your public ip.
Access from outside your machine should be configured by default. You may check if it is so in admin console, at Configurations->server-config->Network config->Listenters. There should be one listening on the desired port (like 8080) and be bound to 0.0.0.0 address.
To easily access something behind a dynamic ip you need something like http://www.noip.com/ or http://www.dnsomatic.com/ (I took these from my router's control panel)
I did this recently,
first you need to use port forwarding on your router, access it by typing your default gateway path, mine was 192.168.0.1 then go to "advanced settings -> Port forwarding". Simply enter the details that are asked for, I set mine to HTTP using port 8080, yours might be different. Protocol is TCP. The IP address it asks for is your local address.
For quick testing you can disable the firewall on your machine and then you can search on google for your Public IP address by typing "what is my IP".
Then type your ip into the browser and the port number "ipAddress:portNumber"
You should see the glassfish welcome screen if it is successful.
After that you might want to enable your firewall again but then you have to add an inbound rules to allow the port to be used:
Setting Windows inbound rules
Then you still have one last step to perform, allowing glassfish to access the resources on your machine: Adding glassfish to allowed programs
Follow the instructions on adding java.exe only.
I want to make my site available world wide. Im using xampp server for hosting. I have no access to any kind of servers and modems. Situation is shown below:
My site server has local ip assigned by wifi router and it runs Windows 8.
Remember I have no access on any kind of servers and modems so port port-forwarding is impossible (out of my scope).
Its actually difficult, but not impossible.
One way, I would approach this is:
I would host a page on internet.
Then take request and store it in database.
One of my program will always be running from my computer.
Then check for request and curl the request to localhost. For this you may use Node.js (taking data from database using GET method and curl it to localhost).
This is the best I could think of. And I am working on it, when the code is ready I'll make it open source and notify you :)
But still, it's difficult, as you need to put user's request to sleep for 2 seconds and then transferring it.
Its slow, but may work out for you.
Disadvantages:
Program will be very slow and memory usage will be more.
Breaking may happen many times.
High bandwidth wastage
If not encrypted, MIM (Men in Middle) may possible.
Advantages:
Indirect method of hosting
Need not to worry about your code being lost.
I am looking forward for a better alternative and I would like to keep this question for bounty once again.
If you cannot open the necessary ports within your LAN you will require access to an external server. However, the external server does not need to host any code, e.g.
Create a Linux based ec2 instance using Amazon's free tier.
Install a package to redirect remote to local ports:
a. using socat:
Install socat using your distributions package manager
Connect via SSH: ssh -N -R 42500:127.0.0.1:80 -o ServerAliveInterval=60 ubuntu#xxx.xxx.xxx.xxx -N -R 8080:localhost:80 "socat TCP-LISTEN:8080,fork TCP:127.0.0.1:42500"
b. using a webserver and reverse proxy:
Install apache or nginx and any required reverse proxy modules and configure your VirtualHost to proxy requests to a local port, e.g. :8080 -> 127.0.0.1:42500
Connect via SSH: ssh -N -R 42500:127.0.0.1:80 -o ServerAliveInterval=60 ubuntu#xxx.xxx.xxx.xxx
Your machine is now reachable via the ec2 instance http://xxx.xxx.xxx.xxx:8080/.
I occasionally use this technique when debugging web service callbacks.
Update 17-02-2014
If you are a Windows user you will need to install a third-party tool to support ssh. Options include:
cygwin
git bash
PuTTY
PuTTY is the easiest choice if you are not familiar with *nix tools. To configure remote port forwarding in PuTTY expand the following setting: Connection -> SSH -> Tunnels. Given the previously described scenario, populate Source port as 42500, Desination as 127.0.0.1:80 and tick the Remote option. (You may also need to add the path to a PuTTY compatible private key in the Connection -> SSH -> Auth tab depending on your server configuration.
To test you have successfully forwarded a port, execute the command netstat -lnt on your server. You will see output similar to:
tcp 0 0 127.0.0.1:42500 0.0.0.0:* LISTEN
Finally you can test with curl http://127.0.0.1:42500. You will see the output of your own machines web root running on port 80.
if you don't have a public IP address and cannot use port forwarding it is impossible to host the site
As people have said you need a public IP address. However, even if you did you should not use xampp as a public server, as it is designed for development and therefore has some security settings disabled.
I would recommend buying some shared web hosting, and uploading it to that. (you can get cheap hosting if you google 'shared web hosting', plus free .tk domains are avaliable: http://www.dot.tk/)
Do your company has any vpn network?
If it does and you have access to the vpn network, you can include your server to the vpn network and your guest will only need to login to your company vpn network then access your site like in a local network without using port forwarding. And since your data is very confidential, I assume that using vpn will also help to increase the security of your data.
Please correct me if I'm wrong.
Thank You.
What you are asking is not possible without port forwarding.
Lets break it into steps.
To host your site locally you will need a IP that is static so that
users can access it specifically.
You will need a domain so that it can be converted into user friendly name.
A 24x7 Internet Connection is must! You added a Wifi Router in your Diagram and most of today's router are capable of port forwarding.
What i will do in your scenario is:
Instead of using XAMP, i will install WAMP because i am more familiar with it and easy to configure.(totally personal preference)
Then i would set my server "ONLINE".(Google how to set WAMP server online)
Forward port "80" from router settings to my local computer ip address.(mostly it is tagged as "Virtual Server","Firewall","Port Forwarding",etc vary router to router in settings)
Suppose you have a local ip "192.168.1.3" and global/router IP "254.232.123.232" then you would redirect all the HTTP request done towards router to your local IP.
[[[[254.232.123.232]]]] --+ :80 +-- --------->192.168.1.3
That is good for now, but then you will need to tackle dynamic IP problem of router. But don't worry, thanks to some free sites that will be easy!
Go to no-ip.org -> Setup Account -> and create a entry, just a subdomain for now to test whether everything is working fine.(subdomain like mysite.no-ip.org, later purchase a real Domain)
Input your IP address there(Router IP) and download its application which will automatically update their server if your local IP changes.
Wait for some minutes and Voila! Your site is live.
I've created literally dozens and dozens of web servers in my day, but this is my first attempt with Windows Azure and I'm running into some problems. I just started migrating from AWS recently.
First of all, I'm running Ubuntu 13.04. Firewall disabled (for debugging), Apache2 installed correctly (using apt). SSH works fine as do many other services with both the DNS hostname and public IP. Virtual host is set up correctly and validated. However, I cannot access the HTTP website either through the Azure provided subdomain or the virtual IP. It just times out.
This is also my first time using Ubuntu 13.04 as well. So, through the powers of deduction, I'm assuming there is something I'm missing either with this new version of Ubuntu or some quirk in Azure. Does anyone have any suggestions?
SOLUTION
These steps to create "endpoint" works fine for all VPS:
open "virtual machine > endpoint > add endpoint"
choose "next"
set "name:http, protocol:tcp, public port:80, private port:80"
choose "complete"
and then must wait for activation and then for some time.
If you are using Azure Resource Groups along with your VMs (which is available on the new portal) you cannot use endpoints because it's not available there, so you should follow the following to open up the HTTP port or ANY other port:
1- Select the VM that you want to manage ports on.
2- In settings, click on Network Interfaces and select your network.
3- Go to Network Security Group and select your group.
4- Add Inbound or Outbound security rules depending on what you need.
I have an AWS instance running Apache server.
Apache is running when accessed from the local machine.
RDP connection through the elastic IP is working.
Port 80 is open for the security group
However, the elastic IP is not accessible from the browser.
Any ideas?
It could be a Security Groups is not configured to allow HTTP.
Go to http://aws.amazon.com Sign in.
Click on EC2. Then click on Security Groups. Click on the Security Group that your instance is using.
Click on Inbound tab. Click on Edit button.
In here, add you IP address (or Anywhere) for HTTP.
Unfortunately, that is not enough information for me to provide a definitive answer.
Here are some questions you can ask to help you figure out what may be wrong, however:
What happens when you run telnet 50.40.30.20 80 (where
50.40.30.20 is your EIP)?
You mention that RDP is working, is this a Windows instance (which requires port 3389 to be open for RDP)? or is it a Linux instance that requires port 22 to be open for SSH?
If Linux, is SELinux running? If so, you may find
this helpful
in disabling it temporarily or permanently to see if it has an impact on your ability to hit Apache.
