What is your Craftbukkit version?

its: [INFO] This server is running CraftBukkit version git-Bukkit-1.2.5-R1.3-20-g45703c2-b2195jnks (MC: 1.2.5) (Implementing API version 1.2.5-R2.0)

EDIT: just updated to most recent

Soooo... 1.2.5-R3.0?

@PartyPoison98
Your GM build, as displayed in the error, looks outdated; You should be on version 2.x.x if you're on a recent bukkit build.

Remove your old GroupManager (and GroupBridge, if you're using it) and install EssentialsGroupManager.jar and EssentialsGroupBridge.jar, dowloading them from this link.

The problem probably wasn't due to Promotions; it was most likely due to your GM being outdated.

Deleting the groupmanager folder fixed it for me. It worked fine before I installed Promotions though

Glad you found the problem

Seems like basic server problem, but I am stumped.

I was running vanilla minecraft server, and could connect localhost and other LAN users no problems. After install craftbukkit (downloaded two days ago), localhost works fine, but other LAN users cannot see the server. Switch back to vanilla server, LAN users work again; switch back to craftbukkit, LAN users can't see it.

Searched quite a few forums, but not finding many ideas about how to investigate, as all the hits involve portforwarding, which I am not trying to do. So, sorry in advance if this is answered somewhere.

Any advice or hints greatly appreciated. Running on Windows 7.

@BossCraft
What do you have in the "server-ip" line of your server.properties? Is it blank, like so:

Code:

server-ip=

Since you're on a LAN, meaning the same network, I don't think port forwarding is necessary or pertinent.

I don't have much experience with LAN networks and none what-so-ever in regards to minecraft (Xbox LAN, anyone?). What ip are your LAN users trying to connect with?

@m1StRm4N
Does it bother you that I just reverse capitalized your name?

Nope

Ah, good to know.

server-ip is blank, like you show. I also tried putting my server-ip in there just to see if that had any effect, but nada.

I have since discovered that turning off the public firewall on my server box makes the bukkit server visible. Which is odd, because my users are all connecting internally on my home network. I mean, these computers can all access each other's hard drives etc.

At least I have a starting point now, though still unsure whether this odd behavior is specifically bukkit related. As mentioned, vanilla minecraft server worked without changing anything on the firewall.

@BossCraft
That is strange.

I would suggest trying to port-forward your minecraft port and seeing if that accomplishes the same thing as turning off the entire firewall - making your server accessible to your LAN players.

I can understand why you would not want to port forward, because it creates a potential exploit, but I would recommend you try it for the sake of testing.

If you discover that port-forwarding doesn't solve the problem, then, by all means, re-block the port.

But, if it does solve the problem, you'll have a more pin-pointed problem area. At this point, you could go ahead and re-block the port.

I just think it would be conducive to locating the problem if you port-forwarded to see if your problem is directly related to blocked ports.

i figured out what the firewall problem is. My vanilla minecraft is configured to use javaw.exe, but bukkit is configured to use java.exe. Not sure why I did that - I probably copied those directly from their respective instructions, and one says javaw and the other java.

The javaw file was permissioned on my firewall, but java wasn't.

That doesn't answer the question about why the public network is being used and not the private one, but at least it is now consistent.

I appreciate your responses, they helped get my brain working.

@BossCraft
A logical explanation, I love those!
Glad I could help, @BossCraft , in whatever way I did :3

What's the question you're still not sure about - could you clarify/specify it a bit more (getting late, so I'm a bit scatter-brained)? I'm not sure I'm more qualified to help you with it, but Im sure we could manage to come up with a solution as to why it's happening. It might not be crucial to your server, but understanding your network and how it fuctions is always a handy convenience.

Boing!

Would I be able to run a bukkit server on 6 GB of ram with a low download/upload speed?
I have a 32 bit Window XP laptop

I originally posted this on the Something's not working post, but thought better of it:

Hi, I'm using the file craftbukkit-1.2.5-R3.0 to set up a server.
I have a Windows 7 64-bit system with a 32-bit version of Java 7 (Update 4) and JavaFX.
I deleted JavaFX in case this was messing things up, but that doesn't seem to have helped.
Java resides on my machine at C:\Program Files (x86)\Java\jre7\bin\java.exe.

I'm still having the "unable to access craftbukkit.jar" error. Here are my files.
( http://s16.postimage.org/8jux7w6k5/Craftbukkit_files.png )

I've tried renaming craftbukkit-1.2.5-R3.0.jar to Craftbukkit (as above) and craftbukkit, and leaving it as-is, and changing the name in the bat file to match the long, versiony name of the craftbukkit filename.

For the bat file, I've had it titled Run.bat (not with the .bat visible, but as in the screenshot in the Something's not Working post.) I've included several versions of the Java path, and
@ECHO OFF
"C:\Program Files (x86)\Java\jre7\bin\java.exe" -Xmx1024M -Xms1024M -jar Craftbukkit.jar
PAUSE
Seems to work best--it gets me to the "unable to access craftbukkit.jar" error.
If I use
@ECHO OFF
IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="64" "%ProgramFiles(x86)%\Java\jre7\bin\java.exe" -Xincgc -Xmx1024M -jar "%~dp0craftbukkit.jar"
IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="86" java -Xincgc -Xmx1024M -jar "%~dp0craftbukkit-0.0.1-snapshot.jar"
PAUSE
It gives me a similar message (after I moved the BUKKIT folder to my desktop):
"unable to access jarfile C:\Users\User\Desktop|?Minecraft Server -- BUKKIT\craftbukkit.jar"

By contrast, using
@Echo OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles%\Java\jre7\bin\java.exe" -Xmx1024M -Xms1024M -jar craftbukkit.jar
PAUSE
or
@Echo OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles(x86)%\Java\jre7\bin\java.exe" -Xmx1024M -Xms1024M -jar craftbukkit.jar
PAUSE
or
@Echo OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
java -Xmx1024M -Xms1024M -jar craftbukkit.jar
PAUSE
the batch file seems to fail due to a path problem--they generate this error in the terminal window:
The system cannot find the path specified.

I looked for the GUI system mentioned in the Something's not working thread by ZeroZX4, and get a 404 error.
His run2 j7 32b file gives me the same "cannot find the path specified" error.

One thing occured to me as I edited the file over and over. I put my BUKKIT folder into my
Program Files (x86) folder, so as I edited and reedited the bat file, I needed to run notepad as admin,
and click through lots of user access dialogs. So I tried moving the whole BUKKIT folder to the desktop,
in case some access/permission problem was at the root of things, but no joy.

Any help is much appreciated, thanks! I'm sure I'm missing something silly, but can't seem to find it.

Low download/upload speed is not enough info.

What's your CPU(Almost certainly good enough if you have 6gb ram) And what exactly is your d/u speed?

I looked here and found this--I can imagine Bukkit could me more resource intensive:
Players RAM Upload Speed Download Speed
2 500 MB or more 512 kbps 1 Mbps or more
3 500 MB or more 1 Mbps 2 Mbps or more
4 500 MB 2 Mbps 3 Mbps or more
6 1 GB 2 Mbps 3 Mbps or more
8 1 GB 3 Mbps 10 Mbps
9 2 GB 3 Mbps 10 Mbps
12 2 GB 4 Mbps 10 Mbps
15 2 GB 5 Mbps or more 10 Mbps
20 3 GB 10 Mbps 10 Mbps
30 4 GB 10 Mbps
10 Mbps

People used to be able to join my server but can't now. I can though. People say it's something wrong with my configuration. What do?

My server has been running fine for a while, but I downloaded the new build (1.2.5 R.3) and now it says End Of stream whenever anyone (even me) tries to join. please help!

EDIT: Also now I can't join any other servers...

OMIGOSH. I had a facepalm moment. i had to have the 1.2.5 client, not the snapshot. ALL FIXED. sorry

My CPU is:
Microsoft Windows XP SP 3 Verision 2002
Intel(R) Core (TM) 2 CPU
T7200 @ 2.00 GHz
2.00 GHz, 2.00 GB of RAM (My friend is giving me 6 GB of ram later)

Ping: 45 ms
Download Speed: 2.02 Mbps
Upload Speed: 0.42 Mbps

Boing!

I think I solved this one--I think that notepad added a .txt to the file by default. (grins sheepishly)

I'm gonna try and sneak in here to try and get some help...

@M1sT3rM4n Is pairing server admins with other potential staff included in community building? If you could play matchmaker for myself and some reputable members of the bukkit community that would be great. Otherwise, I'll just keep waiting for mr/mrs right to stumble on my server.

Boing!

Yep. But like a merger & acquisition IRL, you have to think about the benefits and costs of bringing said individuals into the community. The last time I attempted a M&A with another community it resulted in much sadness.
