I have a database currently running on localhost. I want to access it over the internet, but I don't know how to access and change its settings. I can only use ODBC mechanism to connect to it not SQL server. Please suggest a working link for the problem. Thanks in advance to respected community members.

I have an ASP.NET 2 (very old) web app that I am trying to migrate to a new server. BTW, I am a complete ASP.NET noob but have a good amount experience with other web technologies.
In the web.config, I can see the following connection string XML:
<connectionStrings>
<add name="myCon"
connectionString="Data Source=DEVELOP\DEV_SQL2008R2;Initial Catalog=QO2_New;Persist Security Info=True;User ID=sa;Password=q"/>
</connectionStrings>
I did "nslookup" on the machine name 'DEVELOP' and RDP into the server. To my surprise, I don't see any SQL Server process running. Also, there is no SQL Server installed on that server. I am 100% that the app is running and I am very confident that there are content that comes from the database. I also did a search on the code base and it seems like the connection string is being used.
On a side note, we do have some other databases on separate machines. My questions are the following:
Can the machine DEVELOP somehow redirect the DB connection to somewhere else? If yes, how do I find out which IP is it being redirected at?
If DB connection cannot be redirected, then what is going here exactly?
Unfortunately, I have very little people whom I can ask what is going with this app. Any tips that you can share is much appreciated.
Nslookup uses DNS but there is a chance your machine has a hosts file entry that points DEVELOP to somewhere else..
However, if you RDP'ed into DEVELOP (as in, used that name when connecting RDP, not the ip address given by nslookup) then you should have been able to see a sqlserver install in the list of services.
If there is surely no sqlserver installed there then, from within your RDP session, use TCPView from sysinternals to see what process is listening on port 1433. Could be some kind of TCP redirector like PortTunnel from SteelBytes, bouncing the connection somewhere else. Remember to run tcpview on the server, not your local machine
Perhaps you can try getting connected to the sqlserver using management studio, using the credentials in the web config, you can get sqlserver itself to tell you more about where it is running, such as:
SQL - Query to get server's IP address
Using Environment variables in T-SQL
I am truly ashamed to inform everyone that the database in the web config was never being used. Therefore, even though it is pointing to a non-existing database, it still works. The data from the old database have been converted to static files.
I should have checked this the first thing I came across it. Thanks again for all the help.
I'm going to be making a fun Python project for myself. This is non concurrent. Only me will use this. I would have a desktop version of the app, with the DB on it. And then my phone would have an app that accesses the information on the DB over network and display the data I want.
For most of the SQLite checklist, seems like a perfect fit for a single user super small project. Except the network part is confusing. Some say no, or yes it's doable but not great. What's the consensus here? If I want to access my DB from my phone from anywhere, is SQLite capable? What problems could I run into with this...
You would have to host your DB somewhere accessible from the internet. By doing this, you open it up for attacks should someone get your server address. You can secure this by setting up a VPN from your phone to the PC, this would allows you to run the SQL server as just a local instance only accessed if you're on the VPN. SQL Lite should work just fine under a VPN setup since it won't require the server to have an open connection out to the internet.
As for problems. If you are somewhere where you cannot establish the VPN connection (firewall, port blocked, etc) you will be cut off from your server.
I had installed oracle 11g in my system. I want to access oracle, especially oracle-apex from other PC in the same network. I am able to work on oracle apex via my pc. Since, it is being hosted locally,I was able to access within the PC. I tried with ip adderess from other PC in the same network. But I couldn't.
Thanks in advance.
Do you have any external Apex listener or is this integrated XML DB HTTP server? in the latter case a change in the configuration might help
try running
DBMS_XDB.SETLISTENERLOCALACCESS (FALSE)
Also, pay close attention on the server configuration, for example http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm and many other resources
We are a few web developers and currently edit our host file to point domain names to the local web server but this is becoming hard as number of clients are increasing and we need to continuously change each host file of computers.
What do you think is the best possible solution for us, use a proxy server or a dns server, and could you possibly tell me how to fix this problem?
Thanks in advance
I would use a DNS server, or use mDNS, on your LAN. Then an administrator can simply add an A or CNAME entry to the zone, and all the computers on the LAN will see that record.
I have a web application I have developed on a server on my home computer. Is it possible to access that web page from another computer on my home network?
My naive approach was just enter my ip address followed by the port number :8888 which the server is listening on...
Any help would be great thank you.
I don't know if it will help but you can use an ssh connection to your computer. But you need to do it from a shell (from terminal on a mac, use putty on a PC)
In the end it was easier to set up remote access to the server by setting up port-forwarding on my router and using no-ip for DNS management. They have a decent walkthrough to get it all up and running. So i simply have to type in my-address.no-ip.org to access my site from any remote device.
Otherwise the links to questions on superuser that Sampo posted are worth a try.
