How to access Amazon EC2 files via web browser - amazon-web-services

So I have an Amazon EC2 Free Tier Instance with Debian Jessie. There's a software running that generates an html file I'd like to access remotely.
When connected to the instance via SSH, I can remotely open a web browser and go to 127.0.0.1:8083/index.html?PARAMETER1=...&PARAMETER2=...
Now doing this is very tedious because the browser is slow. I'd like to be able to access to this file directly using the web browser in my local machine.
How do I do this? I tried replacing 127.0.0.1 with the Public IPv4 but it won't work. Do I have to open the port?
Thanks.

You would need to open port 8083 using the security groups inbound rules for the ec2 instance. Then use the public IP to access the file.

How do i set a public URL when using EC2

I have an instance setup for a test site using Amazon Web Services listed under EC2.
I then setup an Elastic IP which as i understand is a static IP.
Once logged into this instance of Windows Server i setup a site in IIS which runs locally.
I have set all the bindings in IIS but struggling to figure out how i assign a public name to this instance so i can view the site in an external browser? I tried entering the IP but that doesnt open anything, not even the standard IIS page?
Check your firewall if you have opened the port 80 or whatever the IIS is bonded with
and also check your security group of the EC2 instance and open the port 80 to the world

Accessing a dev server when doing remote / cloud development

I'm attempting to find a completely remote / cloud-based development workflow.
I've created an aws free-tier ec2 instance and on that box I've been developing a gatsby site (the framework doesn't matter, the solution I'm looking for should be framework agnostic). Since the code is on another box, I can't run the dev server and then from the local computer hit localhost as I would normally.
So,
What do I need to do so that I can run gatsby develop and hit my dev server that's hosted on the ec2 box?
How do I provide public access to that endpoint?
Is it possible to provide temporary access so that when I log off of the box, it's no longer accessible?
Is there some mechanism I can put into place so that I'm the only one that can hit that endpoint?
Are there other features that I should be taking advantage to secure that endpoint?
Thanks.
I can't run the dev server and then from the local computer hit localhost as I would normally
You can. You can use ssh to tunnel your remote port to your localhost, and access the server from your localhost.
What do I need to do so that I can run gatsby develop and hit my dev server that's hosted on the ec2 box?
ssh into the dev server, run gatsby develop and either access it on localhost through ssh tunnel or make it public to access through its public IP address.
Use sshfs to mount a development folder on the dev server onto your localhost.
Alternatively, you can setup vncserver on the dev server, tunnel vnc connection using ssh, and access the dev server using through a remove desktop. Something liteweight would be good, e.g. fluxbox as a desktop environment for vnc.
Is it possible to provide temporary access so that when I log off of the box, it's no longer accessible?
yes. through ssh tunnel. You close tunnel and the access is finished.
Is there some mechanism I can put into place so that I'm the only one that can hit that endpoint?
ssh tunnel along with security group to allow ssh for your IP address only.
Are there other features that I should be taking advantage to secure that endpoint?
Security groups and ssh tunneling would be primary choices to ensure secure access to the dev server.
You can also make the endpoint public, but set security group of your dev server to allow internet access only from your IP.
You could also put the dev server in a private subnet for full separation from the internet. Use bastion host to access it or setup double ssh tunnel to your localhost.
Other way is to do all development on localhost, push code to CodeCommit and have CodePipeline manage deployment of your code to your dev server using CodeDeploy.
You can also partially eliminate ssh by using SSM Session Manager.
Hope this helps.

How to open outside access to ElasticSearch server hosted on Windows EC2 instance?

I didn't find such guide or articles how to do it for ElasticSearch hosted on Windows server.
I have the EC2 amazon windows instance which running ElasticSearch server on port 9200, but I can't achieve it by _ec2_ip_adress:9200 outside the server.
I completely sure that all TCP ports are opened in amazon security group rules, I've turned off the firewall on the server as well.
So that is the problem in ElasticSearch configs.
Can someone help me with that?
Well but you know that then any body would be able to delete/create stuff in your index until you have shield.
If you really want to open it, also make sure that in windows firewall you opened port 9200.
So what i would do i would probably restrict in firewall on in Amazon access to this port for specific IPs (Actually in my project i am doing that :) )
There is one more thing to check on which IP is runned as soon as i remember ES will run on private IP. Look to network.host default is __local__. Try network.host: 0.0.0.0

Connection getting refused to socket.io server on Amazon EC2

I have set up a a micro EC2 instance on AWS. Currently, I am using the free tier in Oregon. There are two problems which I am facing.
When I try to SSH the instance using the public DNS, it says host does not exist but when I try conencting it using the public IP, it connects to it. What setting is needed to use the public DNS ?
I have opened the SSH client using the IP address. I want to set up my application which needs Node.js and MongoDB. I installed Node.js using this
Next I installed MongoDB using this
Then I connected to my instance using Filezilla and uploaded my code to it. I then start my node application which uses socket.io.
When I try to connect to socket.io server using web browser, I get a message which says connection refused "error 111". I have opened TCP port 80 in instance's security groups. In iptables, I have forwarded port 80 to 8080, but still it does not work. I have also checked that the firewall is disabled in ec2. Kindly help me to resolve this issue.
Did you check if all of the necessary ports are open on Amazon Security Policy?
What you can do is to allow all traffic on Amazon Security Policy for test and see if the connection goes well or not.
You might also check if you need access DB from outside. In that case, you also have to open the mongodb port and setup mongodb correctly as well.
Other tools that might useful to test firewall and connection issue will be tcpdump and syslog file
For the dns issue, did you try to nslookup on that name and see if the IP shown matches your server IP?
As Amazon gives a long DNS hostname for the server, I always use my own domain name. It's much easier.
example : ec2.domainname.com, which points to the Amazon IP address
Hope that help.
My problem is resolved now..
For the DNS issue, earlier I needed proxy to access internet, so I guess the DNS name was not getting resolved. When I tried using proxy free internet, I was able to ssh using public DNS.
And regarding connection to socket.io, I used port 8080 instead of 80 and used "sudo node main.js" to run my node file. Now I am able to connect to the socket.io server and MongoDB.
Another thing which I want to ask is that would running the node file with sudo rights create some security issue ?
Thanks for the answer! That also worked for me. I had the same problem trying to connect through sockets (http://myipaddress:3000) to a node.js server, i tried opening ports on the actual ec2 instance and disabling the firewall through SSH but nothing worked. Had to go to Security Groups on the ec2 console and open a new inbound tcp rule enabling that port

Cant host content with amazon ec2

here is what i have done:
I've opened up post 80, 22,21 in the amazon e2 security settings
i have putty and putty gen
i have putty and pem keys
i created an index.html file in the public_html directory using Win_SCP
nothing loads
http://ec2-107-20-57-133.compute-1.amazonaws.com/
Putty keeps telling me the connection refuses no matter what i put in it.
I can't even login without it disconnecting me. Is this a problem with my own network setting at work , is this a problem with putty config, problem with my amazon account..i dunno
First,
What IP addresses did you allow HTTP, FTP and SSH traffic from?
Next,
Is ec2-107-20-57-133.compute-1.amazonaws.com still the correct instance name?
Then,
Is your web started and running?
Is index.html the actual default document?
I had a similar problem with instances refusing connections. I would suggest you to check the ports open and if they allow the traffic from all IPs. Also, if you are using the default security settings and it refuses the connections, try creating your custom security profile and open up the required ports and allow IPs.
Also, which OS image did you select while creating the instance?
