Create virtual network interface programmatically

Is it possible to add a virtual network interface with Java or C#. I need to set a bunch of IPs to my computer for a data mining app and I don't have enought NICs (I don't want to buy more yet).

I need full control of virtual cards from the app (create, delete, set IP, maybe redirect traffic).

I am not sure you have a pure Java solution for this.

You have several alternatives.
1. Use a script that will do that for you, writing this solution in perl\shell will be 4-5 lines.
2. You can open a ssh connection to your machine and run the commands from Java. I have such utility that uses trilead-ssh2.

To get it using maven you can use:

    <dependency>
        <groupId>com.trilead</groupId>
        <artifactId>trilead-ssh2</artifactId>
        <version>build213-svnkit-1.3-patch</version>
    </dependency>

For example, this way you should open a connection:

public static Connection newConnectionWithPassword(String host, String username, String passwd) {
    Connection newConn = new Connection(host);
    try {
        newConn.connect(); // Ignoring ConnectionInfo returned value.
        newConn.authenticateWithPassword(username, passwd);
        return newConn;
    } catch (IOException ioe) {
        newConn.close();
        ioe.printStackTrace();
        return null;
    }
}

Then to run your command you can :

this.session = conn.openSession();
this.session.execCommand(this.cmd);

You can use an OS command to create your virtual interfaces from java now. BTW, You can test the results using NetworkInterface.class , that can query a netweork interface on your machine.

Good luck.
