I've got a brand new EC2 VM in AWS and installed SQL Server on it. I've then imported a database and now want to make that data externally accessible.
Can anyone guide me as to what I need to do?
Dont worry this isn't anything sensitive, its just test content at the moment.
Thus far I've turned off the Windows Firewall to ensure that wasn't blocking it, ensured TCP/IP is enabled in SQL but when I try and connect to it from an asp.net application for example (either locally or from an asp.net app running on a different ec2 instance), it just times out connecting (using the public DNS or the private IP adddress of the VM).
What are the steps that I realistically need to do to make this SQL instance available outside of the VM?
Every time you add services to your EC2 instance you need to make sure to allow inbound connections to the needed ports in the security group attached to your instance.
Did you open the port 1433 to allow inbound connections to Microsoft SQL Server?
Here are some basic steps to troubleshooting SQL Server Connectivity:
Is SQL Server running, and on TCP/IP
From the client can you PING
From the client can you TELNET 1433
Can you clarify the network setup, is it like this:
VM > VM HOST > CLIENT on LAN
VM > VM HOST > CLIENT on Internet
Try those troubleshooting steps at each stage.

I created a new windows server + sql server in aws lightsail. I cant seem to connect remotely via ip address. I almost do everything but to no avail.
I tried the ff:
allow remote connection & windows/sql auth via connection properties
allow all tcp/udp ports (for testing)
enable tcp/ip sql config
add static ip address in tcp/ip sql config
disable firewall
Any help is very much appreciated.
Apparently when managing vps, some configurations such as networking are done via the providers interface, in my case its in AWS console. This means that the firewall rule for port 1433 which is used by SQL Server should be configured in the AWS site. There is a networking tab wherein you can add a custom rule to TCP 1433. Also don't forget to set the Server Properties Server Authentication to both windows and sql authentication (Right click the connection > Properties > Security) and then restart sql server service.
There are two version of Lightsail
Window + MS SQL
Window
When we talk about managing port of MSSQL from Networking tab this will work only when AWS setup MSSQL for you.
if you have just took window and then installed MS SQL from your side you need to do following setting:-
Server Server Configuration Manager, enabled TCP/IP from Networking section
and also open in detail and put port 1433 and remove dynamic ports
Create inbound Firewall in window.
Then it will work.
I have SQL server 208 R2 hosted on AWS. Can I access that SQL server through my web application on local machine without VPN?
What connection string we need to give in web.config. So I no need to have SQL server on my local machine.
I can run and test my application without having SQL server on my local machine.
If your SQL Server is publicly accessible, then you can simply connect directly to it. It's a bad practice to expose database servers directly to the internet, however, so don't do this.
If your SQL Server is not publicly accessible, then you can connect to it via an SSH tunnel. You would launch a publicly-accessible EC2 instance, restrict its security groups to allowing SSH from your local IP address, and then use SSH on your local machine to port-forward to the SQL Server via the SSH tunnel. You can then connect your database client to the local port on your machine and that will be forwarded to the SQL server via the SSH tunnel. Here's an example.
The SQL Server will also have to allow inbound connections from your EC2 instance.
Assuming it's the default SQL Server instance listening on port 443, and your EC2 instance has a public IP address, you could do the following:
Enable access to your EC2 instance through port 443 from your local machine public IP.
Configure Windows firewall to allow access through port 443
Ensure TCP/IP protocol is enabled for your SQL Server Instance
Use data source=<the public ip address of your E2 instance> in the connection string.
To enable access to your EC2 instance through port 443 from your local machine public IP do the following:
Go to AWS mangement console.
Go to EC2 Service.
Click on Running Instances
Click on your EC2 instance running SQL Server
Click on one of the security groups listed on the Description tab.
Click on the Inbound tab.
Click on the Edit button
Click on Add Rule button
Select Custom TCP rule on the Type dropdown list.
Enter 443 on Port Range.
Select My IP on Source dropdown list.
Enter "SQL Server from My local IP" on Description text box.
Your public IP address might change over time, so you might need to update the source when this happens.
To configure Windows firewall to allow access through port 443 open an RDP session to your EC2 instance and use Windows Firewall with Advanced Security tool and add the the rule.
To ensure TCP/IP protocol is enabled for your SQL Server Instance do the following:
Open an Remote Desktop session to your EC2 instance.
Open SQL Server Configuration Manager.
Expand SQL Server Network Configuration
Click on Protocols for
Enable TCP/IP protocol if not enabled.
Hope it helps
I'm attempting to set up a Virtual Network in Windows Azure and use it to avoid opening a public endpoint on my (CUSTOM) SQL Server Virtual Machine. However, I continuously get a network related error, stating that the SQL Server wouldn't talk back in time, when trying to access my web application via my cloud service's URL.
I've looked all over the net for tutorials that show how to connect to one's own Custom-created VM instead of one of Windows Azure's preconfigured Virtual Machines, and found little of use. All the suggestions I've found I've tried.
I am working in Windows 7, using Visual Studio 2010 with the Windows Azure SDK installed, SP1.
Here are some details of what I have attempted to do to no avail.
I have:
created the Virtual Network with
its own Affinity Group
a single Subnet
added the Virtual Machine to it
making sure to put it in the same affinity group as the one I created for the VNet
installed SQL Server
configured SQL Server as per this tutorial
Added my databases and a login that I have verified can access the database
Both:
Converted an existing Asp.NET Website to a Web App and added a Azure Deployment Package thing see here for the tutorial I followed
I used r-click->Publish to Azure/Publish for this one, configured to use an existing Cloud Service I had already deployed in the VNet with the SQL VM, and made sure it was in the same Subnet as the VM.
it is also worth noting that this application did connect to a similar VM that was deployed outside the Virtual Network (still in Azure) by opening a public endpoint on port 1433 and using the Public IP address to connect to it.
Used the converted Web App's code in a brand new Azure Cloud Service project configured as per this tutorial (the first one I mentioned)
I attempted both publishing by:
r-click->Publish to Azure/Publish
r-click->Package and uploading it on the Azure Portal
in both cases both to
an existing Cloud Service in the VNet (and Subnet)
and a brand new Cloud Service created in the VNet (and Subnet) and upload package during creation or immediately publish to service as soon as started.
Double checked that all Cloud Services and Virtual Machines I've gone through were in the VNet, and in the same Subnet.
My Cloud service is usually at internal IP 10.4.2.5, and the VM at 10.4.2.4. My connection string is the same as the first tutorial I mentioned only with the proper authentication and my VM's internal IP specified. Connection string follows:
<add name="SQLServerinWAConnection"
connectionString="Data Source=tcp:SQLVMInternalIPAddress;Initial Catalog=MyTableName;User ID=loginName;Password=thepassword;Encrypt=true;Trusted_Connection=false;TrustServerCertificate=true"
providerName="System.Data.SqlClient" />
I also tried specifying Trusted_Connection=true
No matter what I try, I cannot get this application to connect to the SQL Server instance on that VM. I have even added a public endpoint to the VM at port 1433 and tried using its public IP and private IP, to no avail. That was my fallback, so now I'm at a serious loss.
Some implementation details that may or may not have any bearing:
The SQL Server instance is named, not default, so instead of just 'SQLServerVM' in the object explorer in SQL Server Management Studio, it has 'SQLServerVM\SQLServerDB'.
I have the port 1433 opened on the firewall on the VM for any IP range and any user
I will add any additional details (in case you don't want to read the whole tutorials to figure out what I've done) upon request.
There isn't by any chance a checklist available to state the things which need to be done for a web role or website to be able to connect to a virtual machine in its virtual network? That would greatly simplify troubleshooting.
Any suggestions would be greatly appreciated. I would very much like to have this working by the end of the day.
In my case, since our client installed SQL Server on the VM, using a named database instance, the service which hosted the instance I needed to connect to didn't have its TCP port set properly. So my detail that the SQL Server instance was named was indeed important.
If you just cannot figure out why your Web Role (Cloud Service) just isn't connecting to your Virtual Machine in the same Virtual Network, In addition to checking all of the things above in the question, check the following setting:
Log into the Virtual Machine (RDP)
Open the SQL Server Configuration Manager
Expand "SQL Server Network Configuration" in the left panel.
Click on "Protocols for {SQL Instance name here}" in the left panel.
Right-Click on "TCP/IP" in the right panel, go to "Properties..."
Double check that "Enabled" is set to "Yes".
Switch to the "IP Addresses" tab.
At this point, you should see that the "TCP Port" should be 1433 for at least the domain IP (in my case 10.4.2.4 in the "IP2" section), if not "IPALL" or some others.
Note that the "TCP Port" settings on all the "IP{X}" sections may have different values.
IF you don't see this SQL Server instance listening on 1433 (or some other port you are trying to configure):
Go to "IPALL" and change the "TCP Port" to 1433 (or whatever port you like, 1433 is the default that things will send to).
This will allow that port to be listened on for addresses coming to this server from anywhere.
Note that there is probably a cleaner way to do this, but this worked quite well for us.
This allowed me to access the SQL Server instance from all the Cloud Services in that VNet, using only the Internal IP Address of the VM, without a public endpoint opened for the port I configured (1433).
Just in case, here is the working connection string:
<add name="ApplicationServices"
connectionString="Data Source=tcp:{VM Internal IP}\{InstanceName},{port};Initial Catalog={Table};User ID={username};Password={passwd};Encrypt=true;Trusted_Connection=false;TrustServerCertificate=true" providerName="System.Data.SqlClient"/>
Make sure you replace:
{VM Internal IP} with your internal IP address
{InstanceName} with your SQL Server Instance's name, or leave it and the preceding \ out entirely if you have a default instance.
{port} should either be 1433 or whatever port you set open in your VM for that Sql Server instance.
{Table} with the Database table you want to use by default
{username} and {passwd} with those for your SQL Server user. Note that I am using SQL Server authentication here.
It's also worth noting that this did not open my server up to the internet (as expected), as I still can't get at it from the outside world, so it remains secured within the VNet this way.
Hopefully this will help someone in the future.
I'm sure this is out there somewhere but I can't find it and my brain hurts.
I have a VM on Azure. It has SQL Server running on it. I can access it locally on the VM no problem but I would like to manage it from my dev computer via SQL Server Management Studio.
Is this possible and what creds would I use? the VM Login?
Thanks,
R
You need to complete all of the following to achieve what you want:
Add a TCP endpoint for that VM on port 1433 - public & private (you can change the public port if you will).
Configure the SQL Server Instance to listen to TCP.
Enable the incomping TCP port 1433 in the local FireWall rules of the VM.
Enable mixed mode authentication on the SQL Server
Make sure your ISP does not block outgoing port 1433 (a common practice for most of ISVs since 2003' SQL Slammer) - this is overridable with custom Public port for your TCP endpoint.
Than you will be able to connect to the SQL Server in the Azure VM using your local SSMS.
Faced this issue with Azure VM, I can't connect to SQL server.
Completed all steps described in answer above but didn't get success..
It started to work when I set specific port for TCP/IP protocol.
So open SQL Server Configuration Manager, find TCP/IP protocol for your instance, open Properties and set port to 1433 in IPAll section.
I had the same problem, what I should change was:
click on the VM in AzurePortal --> SQL Server configuration --> Change SQL Connectivity to public
then it works for me!
Instead of SSMS you can also use Powershell to check connectivity with SQL server on Azure VM. The detailed powershell script is at the following link -
http://sanganakauthority.blogspot.in/2014/02/connecting-to-sql-server-virtual.html
This saves you from the installation of SSMS on the machine from which you wih to connect to SQL server virtual machine.
How do I connect to SQL Server 2005/2008 using Management Studio or other desktop application over the internet?
Check out WCF Data Services:
http://msdn.microsoft.com/en-us/data/bb931106.aspx
That way, you don't have to totally expose your database server out to the internet, but you get fine grained control over what gets exposed and who (which type of user) can see or modify what.

I finally solved this by:
Changing default SQL Port to 8080 from 1433 (our ISP was blocking)
Turning off Windows Firewall on the server. I know this is not a long term solution, but at least I was able to pinpoint the problem. I had set two inbound firewall rules to allow port 8080 and SSMS program, on the server. I created an outbound firewall rule on the client for SSMS (but don't think this mad a difference).
I had to change all apps to use the new port instead of the default port. I had to configure our router to handle the new port 8080 and forward to the database server.
I will modify the Windows Firewall settings to see what was blocking SSMS.

If you put 'your' SQL server (any brand, I'm not bashing) on the internet ... it won't be yours for long, unless you add some rather effective security measures ...
I suggest you look into VPN.
To be able to access your database over the internet, you will need to make sure that the server that hosts the database is accessible over the internet and the port that the database instance uses is open on that machine. You will also need to allow remote connections using the SQL Server Configuration Tool.
For Management Studio access I would recommend rather than opening the server to the outside to use a VPN solution that allows you to create a secure connection to the server and from there you can use the server name or IP to connect as if your machine is part of that network.
For the desktop application I would recommend looking into having the data be consumed through a web service or WCF rather than needing to have a direct connection to the database over the internet.
Hope this helps.
Firstly, if we put security consideration on the side, you have to configure SQL server (sql surface area configuration) to accept traffic, then you have to open proper ports on you server and allow inbound traffic thru to your router to the SQL server.
When you open sql server management studio in connect to server window and at the server name type the IP of your server and enter your username and password.
correct format : IP\InstanceName
you should have a user on target database.
