    I have recently deleted my old Minecraft Server (the one you get off the minecraft.net) to switch to a bukkit server.

    When I try to run the server it gives me the message:
    "Starting minecraft server version 1.2.5"
    "loading properties"
    "Staring Minecraft server on (what I want the server ip to be):25565"
    "the Exception was: java.net.BindException: Cannot assign requested address: JVM_Bind"
    "[WARNING] Perhaps a server is already running on that port?"

    What do I have to do to fix this? Thank you in Advance!

    Your old java process is still running. Before proceeding, gracefully "stop" your new [bukkit] server.

    If on widows, open task manager, click on the processes tab, locate javaw.exe and/or java.exe, then right click on the java processes and "kill" it.

    If on a Linux OS, open up console and enter the following command:
    killall java -9
    After performing one of the above step, start your server - it should startup without errors.

    I have done this and it still gives me the same thing. Is it because of my old server and I have to change the ports or something like that? I do not know what to do!

    1. Check to make sure that your IP hasn't changed (if static).
    2. Check to make sure your opened port is actually open.

    It's because a process is hogging the port, not because of some firewall thing. It was also a good suggestion to check that you have the right ip address because that would give the exact same error.

    Wild idea: Try connecting to the port when you don't have a server started to see if a minecraft server is running there.

    Killing the java process almost always solves the problem. This is especially relevant if you had an old minecraft server running on the same port. This indicates that the port was opened, assuming people could connect.
    This also tells us that your java process, specifically your minecraft server, was using or "hogging" the desired port prior to this instance - thus the "Cannot bind to port" error occurred because a process is already using said port.

    Are you on windows or linux? If you're on windows, perhaps you killed the wrong java process.
    Regardless, try restarting your server. That should kill any stagnant processes.
