How do I check that a computer are a member of a sutain network????
Hi!
I'm thinking of developing a peer 2 peer client. That should not be a problem. But its a p2p client who only should allow users working for my company. How do I see that the user are inside our LAN?
You probarbly know what I meen.
For points I'd like some code in java och C++ or something simular.
Peace. Mike

The code above would be java specific. Though the WinSock object provides the same functionality.
just set up your firewall to only allow those from your group, based on IP address.
if you fon't have a firewall, try Zone Alarm, it's the best.

It's true that I can use the IP adress when the user is inside our net but we have consultants that are outside out net aswell. Mayby I was'nt clear enough on that.
Ithink I have solved it by making a client based om my own protocol instead of gnutella. then I can make a client that has a built in crypted password.
Thank you guys for getting me on the right track...

If you want to scan for Lan, I'll support checking IP address. But as graham_k suggested...Zone Alarm is the best.It is free for "personal" use.
Are you using DHCP ?
For security you may try out servlets.
Have a look at:

and also some code on socket:

may be helpful.

Sorry I was little late...
servlets may be useful then...

WindowsUpdate has new updates for .NET users; Details follow - Microsoft .NET Framework
The .NET Framework is a new feature of Windows. Applications built using the .NET Framework are more reliable and secure. You need to install the .NET Framework only if you have software that requires it.
For more information about the .NET Framework, see http://www.microsoft.com/net. (This site is in English.)
System Requirements
The .NET Framework can be installed on the following operating systems:
Windows 98
Windows 98 Second Edition (SE)
Windows Millennium Edition (Windows Me)
Windows NT 4.0® (Workstation or Server) with Service Pack 6.0a
Windows 2000 with the latest service pack installed (Professional, Server, Datacenter Server, or Advanced Server)
Windows XP (Home Edition and Professional)
You must be running Internet Explorer version 5.01 or later for all installations of the .NET Framework.
To install the .NET Framework, your computer must meet or exceed the following software and hardware requirements:
Software requirements for server operating systems:
MDAC 2.6
Hardware requirements:
For computers running only a .NET Framework application, Pentium 90 mHz CPU with 32 MB memory or the minimum CPU and RAM required by the operating system, whichever is higher.
For server operating systems, Pentium 133 mHz CPU with 128 MB memory or the minimum CPU and RAM required by the operating system, whichever is higher.
Recomended software:
MDAC 2.7 is recommended.
Recommended hardware: For computers running only a .NET Framework application, Pentium 90 MHz CPU with 96 MB memory or the minimum CPU and RAM required by the operating system, whichever is higher.
For server operating systems, Pentium 133 MHz CPU with 256 MB memory or the minimum CPU and RAM required by the operating system, whichever is higher.
How to use -> Restart your computer to complete the installation. No other action is required to run .NET Framework applications. If you are developing applications using the .NET Framework, you can use the command-line compilers or you can use a development environment, such as Visual Studio .NET, that supports using the .NET Framework.
How to uninstall
To uninstall the .NET Framework: Click Start, point to Settings, and then click Control Panel (In Windows XP, click Start and then click Control Panel.).
Click Add/Remove Programs.

in java it would be something like using sockets.
ServerSocket server=new ServerSocket(1818);
Socket socket=server.accept();
socket.getInetAddress();
The IP returned by getInetAddress should be checked against your LAN-ip numbers. Not for each and every one, just check for the boundaries in your domain.
