    What does this mean, im trying to run bukkit plug ins with a friend, and i created the server and i dont, know why or how i can let him connect to my server, i edited my server properties to my ip address, but when i go to launch my server, it cannot bind it to port, can someone help me troubleshoot it this? I attached a screenshot for clarification.

    You probably didn't close out of your server properly before. Navigate to start, type in "task manager," navigate to processes and end "java.exe"

    You forwarded your port wrong.
    In the server.properties, keep server-port to 25565 and keep server-ip BLANK!
    If your port is not forwarded, you will have to do that next.

    So if I keep my ip blank how people connect to me?

    Your external ip. Whatismyip.com When its blank it automatically uses that.

    Having any ip in your server-ip= line ONLY matters if you have multiple IP addresses on your system, and you want the server to listen on a single IP only.

    You can try tickling the minecraft port from http://canyouseeme.org/
    Click Start, type 'cmd' (no quotes) and hit Enter. Then type 'ipconfig' (no quotes) and hit Enter. Look for your IPv4 address. It should start with 192, 10, or 172. That's your internal IP address, and the address that you need to forward the port to from your router's configuration.
    See above website.

    And remember, leave the server-ip field blank!

    So which ip do people use to connect to me my Ipv4 or my ip from, whatismyip.com

    People who are connected to the same router as the server (people in the same house, possibly neighbors if they can pick up your wifi) would use your internal IP address. People who are connected from outside the router (anywhere else in the world except in the same house) would use your external IP address, from whatismyip.com.

    to test if your ports are working this is the site made to test out ports like minecraft
    http://www.ipfingerprints.com/portscan.php
    paste your exturnal ip into the slot n put the ports as 25565
    CLICK ON ADVANCE AND TURN PING TYPE TO "DONT PING"
    if it works it should say

    Host is up.
    PORT STATE SERVICE

    25565/tcp open minecraft
    or the STATE will say
    Host is up.
    PORT STATE SERVICE

    25565/tcp filtered minecraft

    the service is what your named your ports to b

    It might be closed because the server isn't starting up due to the object heap error. Install any plugins recently? Or have you foxed with the startup command in your .bat file? You might have some java options that aren't playing nicely with your system.

    ^ that website comes up with errors time to time i no my port is open because ive tested it and it works but canyouseeme.org gives me this
    Error: I could not see your service on (my ip) on port (25565)
    Reason: Connection timed out

    reason being that this website responds to what is pinged back at them but the port 25565 is only ment to be pinged to and not pinged back

    where as this website http://www.ipfingerprints.com/portscan.php allows you to chose the option dont ping so you can get the accual correct info either this

    Host is up.

    PORT STATE SERVICE

    25565/tcp filtered minecraft

    or this

    Host is up.

    PORT STATE SERVICE

    25565/tcp open minecraft

    to my understanding u leave out the ip adress forwarded for some modems try that

    I don't think that's your LAN (or internal) IP address, it looks more like an external IP. You need to forward the port to your internal IP address.
