Connection Sql Server Express 2005 Over Internet ?

May 24, 2007

Is it possible to connect to a sql server express over internet or not ?

- I am using a win2003 sp1 server. Freshly installed.
- The server is directly connected to internet.
- For the purpose of the test, I stopped the windows firewall and the IPSec service.
- I stopped SQL server Browser service.
- I find a free port (here : 1401)
- I activated TCP/IP protocol in SQL Server Configuration Manager, and I have selected 1401 as the TCP port in the IPAll sextion of TCP/IP protection (and I remove the '0' of the dynamic TCP Port).
- Restarted SQL server express...

In the sql server log, I get the message "Serveur Server is listening on [ 'any' <ipv4> 1401]"

But I never get an answer from the server.

sqlcmd -S ip_of_the_server, 1401 -U username -P password is working fine if launched on the server. But I always get a timeout error from any PC. Same with a telnet on port 1401.

Any idea ?

Seting Up Sql Server Express For Internet Connection

May 7, 2007

Hi

Im having some problems setting up sql server so that i can connect to it in my vb program over the internet.

Im using windows xp pro and have IIS installed and using sql server 2005 express SP2.

My setup is as follows:

from phonecable to router, from router to wireless access point and the wireless connects to my computer.

I have tried disabling the xp firewall, and in the sql server configurationi have set the port to 11001, which i have also opened in my router.

There should be a connection to the computer, cause i have succesfully set up an FTP server on a different port.

I have also enabled remote connections, both via TCP/IP and named pipes.

I have tried to use telnet on my IP adress with the port 11001, and it says that i cant create a connection..Are there other settings i should set to get this to work? This has been bugging me for a little while...

Sql Server Licensing For Internet

Apr 9, 2001

I am so confused and I am getting no help from the Microsoft, two months and only stammering
from their representatives. I need to set up a Sql Server database that will allow internet access.
This is not an e-commerce situation. At most there will
be 10 known users of this system accessing statistical data. I had priced this system to use Backoffice,
but as I now read this is not legal for internet use. It also appears that a processor license is required for
internet access (not entirely clear on this). Access and MSDE also don't appear to be legal for internet access.
The customer is on a shoe string budget. If I use stand-alone
components the budget only covers an one processor SQL Server 2000 license. I don't like the idea of setting up
a database system with only one processor. Is there another Sql Server based option I am not aware of?
Its looking like a linux/mysql option - Yikes!

Updating 2nd MS Sql Server Over Internet

Feb 2, 2004

Hi,

I'm reasonably new to MS SQL server, I've mostly been setting up databases and creating ASP Pages to look at them with.

However recently I've been given a fun job and I can't seem to find a way to do it.

The problem is we have 2 servers located on different sites, one is actually doing stuff the other just monitors some equipment and when status chages on the equipment a report is made to a table. The software doing this is bespoke and it would cost a fortune to have changed, what we want to do is have the monitoring server send a copy of the inserted row as they get inserted.

I've tried linking the servers via ODBC (in the linked servers part) but when a trigger i've put on the insert table fires it throws up an error about ANSI NULLS and WARNINGS and nothing happens.

After a look round on the internet I've found reference to using the 'set ANSI_NULLS' on command but this seems to be for stored procedures, even then when i try to execute the stored procedure as they show it still comes back with this error.

Can anyone suggest any other ways of copying the inserted row across?

Both servers are MS SQL but are not on a LAN so I have to refere to them as IP addresses.

Cheers,

Iain

Connecting To SQL Server OVer Internet

Jul 23, 2005

I know it is possible to establish a connection to an SQL Server overthe Internet via Enterprise Manager. My question is, how secure is thisconnection? Is there a best practices document for this type ofconnection?Here is my scenario:We are looking to outsource our web hosting. Currently, we uploadclient sensitive data to our SQL Server databases within our internalnetwork. If we outsource, the SQL server will be on a differentnetwork. We are behind a firewall here and the dedicated hosted SQLServer will also be behind a firewall. Is the Enterprise Managerconnection succeptable to hackers? If so any reccomendations on how toaccomplish this would be appreciated.Another scenario is connecting to the SQL Server through a DSN. Canthis be accomplished from inside our network to outsourced server? Howsecure would that connection be?Thanks in Advance.

The connection string is
data source=192.168.0.1XXXX;initial catalog=XXXX;integrated security=SSPI;persist security

info=True;workstation id=XXXX;packet size=4096"

but when we change IP in the connection string to our remote server(in internet with static IP) one we get

an exception says that
SQL server does not exist or access denied.
We opened ports on firewall but problem is still here. Then swithched off the firewall at all

but
same exception comes.
Thanks for answers

Does SQL Server Work Well Over The Internet?

May 17, 2008

I have an Access 2003 application that works well in a LAN environment with a Jet based back end. However, I would like to move this back end to a SQL Server database hosted on a website so that my users could run the application from any Internet-connected PC, using a modified version of my Access front end.

Is this a perfectly normal way of using SQL Server? Is response time likely to be an issue or can careful design make performance similar to that with a LAN based back end?

Ssis Package Can't Connect To Pop Server Over The Internet From Sql Server Agent

Dec 20, 2007

Sql server agent is running under a domain account that is a member of administrators and domain users amongst others, and the package is executed as the service account. Connecting to servers on the same domain works and when I run it from the msdb package store in ssis (ssis runs under the network service account ...) it will connect to the pop server as well. Permissions, fiddly proxies .. the answer's out there somewhere

Connecting Directly To SQL Server Oer The Internet

May 14, 2008

Hi,
I'm currently writing a desktop application that communicates directly with a SQL server database on the local network. Ideally we'd like to connect directly to the database via the Internet.
- connecting via the Internet is important because we want easy access from anywhere.
- directly is important because fast data transfer is a requirement.

Not knowing much about the security implications of such a connection, I thought I'd ask here. So what are the major risks and objections? Can the connection and data be made secure?

Cheers, Gavin

Deploy Local SQL Server On Internet?

Feb 1, 2007

Hello,

Sorry for posting this here, I couldn't find an accurate forum name to post this in.

We are using Windows SBS Server 2003 with SQL Server installed. We have a static IP. I am wondering if we can host our database. I am specifically interested in having outside websites access our database. Is there anything special I need to do to make this happen? I am pretty clueless about this.

Thanks!

Report Server Authentication Through Internet

Mar 6, 2007

We're trying to determine the best way to implement an authentication mechanism for our reporting services solution. Basically, we are exposing a web application to the internet, and allowing a forms authenticated user to access our report server somewhere within our intranet to view reports. I've browsed msdn and found that there are two approaches:

1. create a custom authentication extension for reporting services
2. create a restricted domain user that is allowed to access the report server

Going with approach 2 and assuming I'm using a ReportViewer control, in order to authenticate with the report server (using the one domain user created specifically for report server access), are we supposed to just provide an instance of an object implementing IReportServerCredential containing the domain user information to the Credentials property of the ReportViewer.ServerReport before accessing the report? Is this the correct way to implement approach 2? Also, if implementing approach 2 is so simple compared to approach 1, why would anyone choose to implement custom authentication extension if they don't need fine-grain access control on the report server level?

Thanks for any help and suggestions!

SQL Server 2005 And Security Over The Internet

Feb 2, 2008


Couple of questions for the SQL Server Guru's out there.

SQLServer 2005
Web Hosting Provider

Ok I am developing a Web application in ASP.NET with AJAX, etc. etc. It will be some time before it is ready to roll out. As a mockup I created the same application in Microsoft Access and Visual Basic (VS 2008), which I can link the tables to the hosting provider on the internet. Works very well and speed is very acceptable. The want to start utilizing it with the mockup distributed app that I created.

My question is, is how secure is the data that is moving from the local application to SQLServer 2005 with the web hosting provider ? Is there anything that I can do to increase security ?

Thanks, any thoughts ?

Appreciate any suggestions or comments.

How-to Expose SQL Server To The Internet From Behind Firewall?

Jun 6, 2007

I cannot seem to find the definitive how-to guide for this. Can anyone point me in the right direction?

I have SQL Server 2005 (x64) already running on Windows 2003 R2 (x64). I'm having difficulty trying to expose it the Internet.

Using the Surface Area Configuration tool I can see that remote connections using TCP/IP is enabled. I also made the machine administrator a member of the SysAdmin role from here too.

In Windows Firewall "SQL Server" and "Web" are already checked as exceptions.

I know that SQL Server uses port 1433 and I also read somewhere that clients connecting to SQL Server communicate on a random port between 1024 and 5000. So, on my router (Netgear WNR854T) I'm forwarding ports 1024 through 5000 to the machine where SQL Server lives.

In my connection string I'm using the IP address of the SQL Server machine with ":1433" appended to the address. Yet I cannot connect to SQL Server. Am I missing anything?

Accessing SQL Server Via ODBC Through The Internet

Nov 24, 2006

Hi,

I am migrating from MySQL 5 to SQL Server Express 2005 (SP1) and I am having some remote connections issues. I have tried just about everything that I have read in the forums and in Microsoft's knowledge base about remote connections with SQL Server. I am using Visual FoxPro 9 as my client and connecting with ODBC to SQL Server. The strange thing about my issue is that I can connect just fine with localhost or using my LAN IP address. Before I get to the errors, here is what I have configured:

Remote connections are allowed, TCP is active, SQL Browser service is active and running, my router forwards requests on ports 4567 (my custom port that I setup IP1 in SQL Server Configuration Manager to listen on), 1433 and 1434 (TCP and UDP for all) to my local IP address. My firewall will not block ports 4567, 1433 or 1434 (TCP and UDP for all). I even tried turning my firewall off.

For example, the following connection strings work. The first works when I am at the same computer as my SQL Server, the second works from a different computer on the same LAN.

Driver=SQL Native Client;Server=localhostsqlexpress;Database=xyz;Uid=adm;Pwd=pw

Driver=SQL Native Client;Server=192.168.1.3sqlexpress;Database=xyz;Uid=adm;Pwd=pw

When I try the following connection strings (with either my hostname or internet IP address, I get one of several failures):

Driver=SQL Native Client;Server=my.domain.comsqlexpress;Database=xyz;Uid=adm;Pwd=pw

The above strings yields this error message: [Microsoft][SQL Native Client]SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]

Driver=SQL Native Client;Server=my.domain.comsqlexpress,1433;Database=xyz;Uid=adm;Pwd=pw

Driver=SQL Native Client;Server=my.domain.comsqlexpress,4567;Database=xyz;Uid=adm;Pwd=pw

Using either the SQL default port or a custom port yields this error message: [Microsoft][SQL Native Client]Login timeout expired Connectivity error: [Microsoft][SQL Native Client]TCP Provider: No connection could be made because the target machine actively refused it.

The fact that I can connect with my LAN and not on the internet suggests that my ISP may be blocking port 1433. For this reason I tried to change the port my SQL Server instance was listening on but I have a feeling it isn't working.

Any help would be greatly appreciated as I've been stuck on this problem. Is there any way to test if my SQL server instance is actually listening on my custom defined port? Thanks in advance.

-Tom
