Others can't connect to my server. Help Please?

    Just downloaded and started running my first Bukkit server. The only plugin I have installed is Whitelist v2.7

    I am able to log into the server (from the same machine), but others are not able to log in, even though I've whitelisted them.

    Here is the error they are getting:

    Failed to connect to the server.
    Connection timed out: connect.

    Can anyone telling me what the problem is please?

    You will need to open the Minecraft port 25565 in your router, or computer so others outside your nerwork can actually connect to your server. If you use a router, check here for instructions: http://portforward.com/

    Oh btw, I have been running a server previously (the standard one from minecraft.net) and people have been able to connect previously with no problems.

    Do I need to do that port forwarding stuff because I upgraded to Bukkit?

    Also, I don't think I use a router. I just have a broadband modem. How do I tell?

    And since I can connect myself, is this still my problem?

    Hmm...so you only have the single computer connected to that modem, and no other computers in the house can connect to internet?? Test the port anyway when using the bukkit server. Run the bukkit server first, and then just enter port 25565 into the port section in that link I provided, which is the standard Minecraft server port, and if it says Successful in green, then it's not a port issue. If it says Error in red, then people outside your network shouldn't be able to connect to you because their computer can't "see" you computer from the outside, which means the port they need is closed on your end.

    Yes, I only have one computer connected to the internet through that modem.

    I did check 25565 on portforwardin.com although, and it says:

    External IP Address: Your external IP address is:
    Ping Result: We were not able to ping your router
    Port Check Result: Your port is NOT OPEN or not reachable!

    So apparently I need to forward my port, but I don't think I have a router. Can I still forward my port even though I don't have a router?

    First, you checked your port while you had Minecraft server running? Are you running Windows or Mac, which version?
  7. Offline


    No, I had to shut down the server (told me it couldn't check because another program was using the port atm, so I shut down the server).

    I am running Windows 7 on a PC. Like I said, I've had a standard server running before and didn't have connectivity problems. This problem has only happened since I switched to Bukkit/Whitelist v 2.7

    No router, only a broadband modem (an Arris TM602G).

    Don't use the application from portforward...it best to use the program you are actually trying to run. Maybe that Whitelist plugin is giving you the issues, so try and move that plugin out of the server folder just to test this. Open your bukkit server and leave it running, then go to this link http://www.canyouseeme.org/ and enter port 25565 for Minecraft, and it should say either Successful or Error after a few seconds. If you see Error, then use this link to help you open a port in the Windows firewall(make 2 rules, one with TCP, and one with UDP for port 25565): http://maximumpcguides.com/windows-7/open-a-port-in-windows-7s-firewall/

    if your ip is always changing use the static app from portforward.com
    their portforwarding tool SUCKS

    Uh.. this is what I get from canyouseeme.org:

    Error: I could not see your service on on port (25565)
    Reason: Connection timed out

    So I followed the instructions to make new rules for port 25565 on TCP and UDP and did canyouseeme.org:

    Error: I could not see your service on on port (25565)
    Reason: Connection timed out

    Same thing! Uggh...

    Modem: Arris TM602G

    Also, I did move the Whitelist v2.7 out of the server folder as well.

    Sorry, I noticed you had posted model in earlier post...Yeah, that's definitely a modem only, normally seen with Comcast service. Do you still happen to have the older standard non-bukkit server somewhere? I just want to see if you run that standard server, and check the same 25565 port again, if it says it's actually open or not, since you said people could actually connect previously...and there might be another way to allow others to connect using a program called hamachi, but I've never used it myself. Maybe someone else can help with that route.

    Yep.. if I open up the standard server (the one from minecraft.net) and canyouseeme:

    Success: I can see your service on on port (25565)
    Your ISP is not blocking port 25565

    Odd... whatever the problem is definately seems to be associated with Bukkit.
  13. Offline


    Hmmm...then the bukkit server should also be using the same exact port when you run it...very odd. In the bukkit server folder, if you open the server.properties file with notepad, does it say "server-port=25565" ??
  14. Offline


    yep :(
  15. Offline


    In that same server.properties file, is there an IP listed under "server-ip= "?
  16. Offline


    No ip listed:

    #Minecraft server properties
    #Thu Mar 17 06:02:37 CDT 2011

    Should I be listing my ip there?!?!!

    If so, I tried it, and I still cant see myself on canyouseeme

    No, you want it blank when you don't use a static IP...I really don't know why it would be blocking the port with bukkit, but not with the standard server, since either way it uses the same port...
    Ok, let's try one last time to get some info, see if I can't figure something out.
    1. What version of Java do you have installed? In command prompt window, you can type "java -version" to see version info.
    2. What craftbukkit build are you using? When you run the server, you'll see a line that says "This server is running Craftbukkit version git-Bukkit-x.x.x-xxx-xxxxxxxx-xxxxxxx", just post the whole line that looks like this...
    3. What is the text in your batch file(that .bat file you had to create) you use to run the server?
  18. Offline


    Java version 6

    This server is running Craftbukkit version git-Bukkit-0.0.0-544-g6c6c30a-b556jnks <MC: 1.3>


    SET BINDIR=%~dp0
    "%ProgramFiles%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -jar "%BINDIR%\craftbukkit-0.0.1-snapshot.jar"

    I don't know if this helps diagnose this problem at all or not, but I can actually log onto the Bukkit server... others just can't.

    Those actually seem correct...your Windows account is the admin account right? And you don't have any other firewall program like ZoneAlarm, maybe even a firewall from your antivirus program? Other than those, can't think of anything else. I was thinking if maybe the standard server can open ports because its a java console program, but the bukkit server uses the command prompt(which non-admin accounts might limit access to). :(
  20. Offline


    How do I check if my account is the admin account?

    I'm a biomedical scientist, not a computer scientist, so this computer stuff frustrates me sometimes.. grrr...

    Oh well.. this is such a fun game, it will all be worth it if I can get this figured out.

    Thanks for all your help though.

    In Windows 7, go to the start button on bottom left, then click on your little picture avatar at the top, which will take you to the User Accounts settings. In that window, it should say right under your username if you are Administrator or Standard User, or Guest...whatever it says is what you are...
  22. Offline


    Yep.. I'm an administrator... Uggh :'(

    Is there anybody in particular on here that would know a lot about this that I should seek out?
  23. Offline


    :'( me too.....only option I can think of to get you playing is to use LogMeIn Hamachi. It creates like a mini server, all your players will have to use Hamachi also to connect to your Hamachi server, but it tricks port settings so they have no problem connecting to you...let me see if I can find a video tutorial...

    Hopefully this tutorial helps you:

    So is this a fairly common problem then for this Himachi software and this tutorial to exist?!

    Since we have determined that this is something that is related directly to the Bukkit server, it seems like this is something the devs would want to address.

    I really don't want to have to ask players to download and install additional software just to be able to get on the server.

    I notice you are fairly new to this forum as well, but is there anyone you know of who is an expert in these matters that I might be able to seek out for help?

    are u sure you have no anti virus or something like that runnning?

    else you can try to "temporarily" disable the windows firewall to see if thats in the problem.
  26. Offline


    I may have missed it but no where do you say that you opened the port for incoming and outgoing traffic in the firewall

    Also. Windows firewall is dumb. Disabling it won't help

    And basic minecraft gets through while bukkit does not unless you make rules

    I did set up a rule for incoming traffic in the firewall. I will try setting up one for outgoing traffic as well. I will also try disabling it.

    The standard server from minecraft.net works though, so it must be something specific to Bukkit.
  28. Offline


    It could very well be the firewall as mughi mentioned. Since the standard server allows people to connect, then the port is opening correctly, but the fact that a similar program doesn't allow connection would mean that a software firewall is not allowing that program to open the same port. Try adding both inbound and outbound rules for Java in the Windows firewall advanced settings for port 25565 using UDP and TCP(this probably means you will have made 4 rules all together, 2 for inbound java, and 2 for outbound java).
  29. Offline


    Ok.. I turned off the firewall, and I think it might be working now. I can at least see myself on canyouseeme.

    Seems kinda stupid, since I made rules in the firewall for port 25565.

    Oh well.. if it works, it works. Can someone try logging in to see if it works?
  30. Offline


    it works, it now says i'm not on the whitelist :)
