I followed cloud guru's course to create a ec2 instance in aws. I installed apache webserver and created a static page. When I login to the ec2 instance and run the curl command (from within ec2 instance) using "Public DNS (IPv4)" address , I am able to view the page in browser. However when I try to open it in my browser, I am unable to view. I did not make any changes to outbound rules in my security group.
I am unable to access the page using the public ipv4 ipaddress both from within ec2 and outside.
I can't comment due to new user. This seems "security group" inbound rule issues. Did you open port 80 in security group "inbound"?
When you use "public IP" even from EC2 box, that will be considered as traffic from internet and if your security group is not configured to accept (inbound) traffic from internet, you can't access the website available on port.
NOTE: Suggest to open port to "MyIP" instead of "whole world".

i get this error for installation script that worked perfect on EC2 vm but now seems that i can't reach the site , should i add some inbound rule or something to enable apache2 server ? the error in the chrome is
This site can’t be reached *.*.*.*.com’s server IP address could not be found.

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 an AWS environment where
for each client, there is a dedicated ec2 windows instance.
There is NO active directory; each ec2 instance is like in its own workgroup.
Each instance is deployed on its own dedicated VPC, security group etc.
Clients use RDP to connect from their site to the ec2 instances whenever required over port 3389.
The clients' ip addresses are known upfront and we open port 3389 to allow RDP connection.
Now we want to introduce the RDP using SSL (port 443)
The typical guides from Amazon and other books walk thru setting up a RD Gateway in a SEPARATE ec2 instance and use that as the jump box.
https://docs.aws.amazon.com/quickstart/latest/rd-gateway/architecture.html#best-practices
This is all good except that,
I do not want to have an additional ec2 within each VPC.
(I understand that there are other options to have a centralized RD Gateway in its own vpc and then using VPC peering etc. But I don't want to go that route for various reasons).
So, my question is:
Is it possible to setup the RD gateway directly on the ec2 instance to
which I ultimately want to RDP into ? and use SSL(port 443) for
connecting thru RDP?
Thanks in advance.
I tried this out successfully. I created an EC2 windows 2016 server.
I installed RD gateway using the powershell command.
Install-WindowsFeature RDS-Gateway -IncludeManagementTools
Then I launched the RD gateway manager.
configured the CAP and RAP to allow my Remote Desktop Users to access any resource.
Used the ssl certificate which I created using certroot in linux.
From aws console, opened the port 443 in the security group to allow connections from my public to the ec2 instance. (No other ports were opened).
From my local computer, I setup a RDP connection such that:
The RD Gateway server setting had the RD gateway server name (ex. poc.mydomain.com)
This should match the ssl certificate.
The remote computer name was specified as "localhost" (implying that the same server needs to be connected to).
After providing the right credentials, I was connected the the ec2 instance using RDP.
I am new to Amazon Web service. I created an Ubuntu 16 instance with AWS. Installed Apache and restarted the service. But still I am unable to figure out how to access the start page from a browser. Which IP address should I use? Public ip or elastic ip? Also do I need to change any configuration file? Thanks.
You need to use the public IP address, depending on your usecase you can even use an elastic IP address.
However you need to configure your security groups in order to access the web page.
Go to your security groups
Select the relevant security group
Add inbound rule to port 80 (TCP)
Then you will be able to access the page. Please refer this guide for more information.
You can use public ip / public DNS. These both will change upon restart of an instance. Elastic IP is useful when you want your IP address to be persistent. e.g. To make an entry in your domain DNS records.
Make sure your default site is pointing to correct directory as you are going to access using IP address.
If your instance is in VPC then it must be in public subnet. (subnet with Internet Gateway route attached)
I am following Tutorial: Installing a LAMP Web Server on Amazon Linux. My web server is started.
Now how do I access the website from my browser?
You will need to assign a Public IP address to your Amazon EC2 instance. This can be done at startup by enabling Auto-assign Public IP, or it can be done later by assigning an Elastic IP address:
Create an Elastic IP address in the Amazon EC2 console
Associate it to your Amazon EC2 instance
You will also want to check that the Security Group associated with your instance is permitting inbound HTTP traffic (port 80).
Then, just put the IP address of your instance into your web browser.
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.
