I'm currently developing a simple multiplayer game app for Android and I need to have a server to which the users connect to.I'd like to set up this server at home. I have a dynamic IP address,so someone told me I'd have to set up a local DNS server or something like that. I'm not even sure where to start with setting up a DNS server, everything I found was for windows 2003 and linux. Nothing for XP? If any one can shed some light on this matter, explain a bit how setting a DNS works or supply a link with "setting up local DNS for dummies" I'd be grateful.
Also, besides setting up a DNS so I can find the server every time, how about the communication with it? I'd like for it to be as secure as possible. Another friend told me something about communicating via SSH, which is again something I am not accustomed to.
So if someone could explain some of these concepts or offer some GOOD link for that that would be great. I'm very confused :)
Thanks
EDIT
Btw, the server is in Java and currently i'm communicating from Android emulator to the server (which is localhost) via sockets.
That's not a simple thing you're trying to achive. First you have to create your own server on your machine (maybe you're done with this step), then you have to make this server available for everyone. At this point, I suggest the DynDNS service:
http://lifehacker.com/124804/geek-to-live--how-to-assign-a-domain-name-to-your-home-web-server
A local DNS by default help you to find your own servers by name instead of IP address, but if you have a usual internet service with dynamic IP, you need an external DNS provider to route your clients to your server. (read the link above for the full explanation)
About the SSH security: Yes, you will need some security settings indeed, but that could be a very hard problem sometimes. You can set your server to work with SSL sockets, which is a part of the core J2SE release. It will work against some sort of attack, but none against others. Running your own server will raise unexpected numbers of problems, prepare for that.
As already stated in the comment to your post, something like http://www.no-ip.com or http://www.dnsdynamic.org would solve the issue with your dynamic ip - You do not need a local DNS server.
With regards to communication, i believe that SSH is linux/unix only. Since you wish to use Windows for the server, FTP or Remote Desktop would be best. Choose FTP if all you want to do is manage your files, choose remote desktop if you wish to manage your entire computer. I've had good results with the FileZilla FTP server on windows (http://filezilla-project.org/)
With that said, i think you would be better off buying a simple and cheap hosted service instead of using your own computer - you can get something that can run your java app for $5/month some places, and compared with the annoyance of having a local server running in your house, it might be worth it.

I'm a software engineer who knows little about domains/AD/DHCP and the rest, But I have a project where I need to test with 2 domains and let's say a SQL Server that has users from both domains. (It's not really SQL Server but I don't think that matters). Anyway, I installed Hyper-V and then Windows Server 2019. The VM came up and I couldn't see the network at all. After some fiddling (I think I set up a static IP address) the VM could then see the network. Then I promoted it to be a domain controller and lost all network access. I can't ping anything on our local network and nothing outside either. I know there's probably no simple answer, but any guidance would be much appreciated.
I currently run an Apache server with Ubuntu 14.04, and also have a TOMCAT server and a Calibre server (running on port 8080 and 8081 respectivly).
I can reach them throught firefox by typing
http://localhost:8080 // For TOMCAT
http://localhost:8081 // For Calibre
I'd like to know what should I tweak or set to be able to reach them by typing
http://tomcat.localhost/ or http://localhost/~user/tomcat
and
http://calibre.localhost/ or http://localhost/~user/Calibre
(I'd like best the first option if possible)
Is this possible to do this without installing a DNS server? (I can use it if needed, but I'd be happier not to use a technology I'm not comfortable with)
I tried a PHP include or redirection in localhost/~user/Calibre/index.php, but this is verry inelegant (and I couldn't get it to work properly anyway)
The goal is to have it used on different computer on my local network (so cross navigators and cross computer compatibility is a better solution, but I'd be happy if it work only on my computer for the moment).
Any help would be greatly appreciated.
Thanks a lot
You should create a virtual host to use multiple domain..Follow the article to archive this..Let me know if you have any queries.

Here's the situation. I developed a simple examination system with registration forms. I used VB.Net as the programming language. I haven't tried manual coding for my problem yet.
Anyway this is a project for the company from which I am an intern.
The plan is to get every client pc to have this examination/registration application and this application will send the personal info and the score to a central database(server pc).
I used MySql as the dbms and developed the application on the same machine which means that the Database server I used is only on the local host.
Now I was about to try to implement the application to one client pc(as a beta test) and installed the necessary files(.net framework) and I also installed MySQL Server(and workbench) in the server pc.
When I run the application in the client PC it didn't detect/connect to the ServerPC's MySQL server instance and therefore was not able to record the dummy values I input in the client application. Take note I changed the connection string of my app to point to the ip address of the serverPC.
Now my questions are the following:
1)What have I done wrong?
2)Should I install the MySQL Server(and Workbench) to every ClientPC so that I can create a server instance that uses the REMOTE HOST option and configure it such that it will connect to the SERVERPC's Database?
3)How should I setup the server so it gives access to the application I installed in all clientPCs?
I'm pretty new to VB.net and mostly learned from internet sources. I haven't tried manual coding. Mainly because the tools in VB.net are slightly easy to understand thanks to intellisense,the drag and drop tools and also the help topics.
Anyway I hope anyone helps me. Advance Thanks and If the information i've given is not quite complete please point out to me which info I forgot to add.
EDIT:
Additional info, the client pcs and the server pc is in one network.
I also granted every privelege to the serverPC settings of MySQL.(it's just for the test run)
Did you enable the MySQL user for localhost only access? You can check this in MySQL control center by browsing to your 'mysql' database, 'users' table, am ensure the host field of the user is set to % and not localhost, allowing them to connect on any NIC, not just the loopback (localhost) adapter.
I'm looking for a way to allow potential customers to try my application before they buy it.
The product is a windows forms application that requires an SQL Server database to operate.
Although I have a functional demo that the customer can install on their network, I want to make it easier for them by have them "play" with it at my environment.
I remember Microsoft had (has?) something similar. I was testing Visual Studio a few years ago in a virtual environment where I was connecting to a server at Microsoft.
They setup the environment this way so when a user logs off after using it rollback his actions. Or to explain it better: when a user logins it starts with a new, clean environment.
So any projects I've created testing Visual Studio were lost after I logged off.
Any suggestions?
Thanks.
Some solutions that come to mind:
Provide remote access
You could provide access to a running instance of your application via some sort of remote connection protocol, e.g. via RDP or via VNC.
For example, there is a Java VNC client which can run as a Java applet; you could put that on a webpage and have it connect to a VNC session you host on your servers.
Or use Windows Terminal Server, and allow connection via RDP.
Both solutions of course have the drawback that people need to open the appropriate ports, if they are behind a firewall. There might be ways around that, however (e.g. you can run VNC over HTTP).
VM image
A completely different solution: Provide a ready-to-run VM image (for VMWare, VirtualBox or similar) of your application, including server and everything. You would need a demo version of your app though, plus getting redistribution rights for all the proprietary components (Windows OS, SQL server) might get hairy.
Offer videos
Often people do not really need to actually use the app; they are mainly interested to see how it works. So maybe it is enough to host videos of the app in operation. That allows you to put in some advertising for your features, and lets you show the users what they might miss when testing on their own.
I am relatively new to iphone development. I have looked through the documentation and cannot really find an answer to this problem.
I have a server which I have created and know the ip address and the port it is using. I am now trying to connect to this using an iphone application I am creating. Through the documentation there are many example where it connects via an ID (such as the witap example) however there is none where it directly accesses a previously created server.
Would anyone be able to point me in the direction of an example that uses this, give me some information or even inform me of another way around doing this? It would be much appreciated. Thanks.
Bonjour is a technology to detect servers in your local network. If you already know it, as you seem to because you know the IP address, you can connect to it using the usual techniques.
It depends on your server, is it a HTTP server? There are some Cocoa classes that might help you.
If it's a custom made server you might consider CFStream or raw sockets.
