    Essentials has a SocialSpy function that does exactly that: allows you to see other players' private messages when you toggle SocialSpy on.

    Alternatively, you could get a simple plugin that logs commands to your server.log and then look at that file for any "sneaky" needs. The drawback incumbent with this alternative solution is that only you, the server owner, can "spy" on people because only you have access to the server.log (I assume). However, having this extension can prove to be useful in many situations, just in general.

    Have you tried running just a vanilla bukkit server for a few hours/ a day to see if the problem persists?

    It could be that a plugin is tampering with some of bukkit's functions, making the error seem to stem from bukkit, itself - though the problem might not be a direct result of bukkit's native functions.

    I don't have a clue why you're encountering that problem, but running a vanilla bukkit server is a good diagnostic test in situations like this.

    On my server, both groups "default" and "builder" are not allowed to use /spawn. Also, default can't /warp. I NEED HELP!

    the permisson nodes are essentials.spawn and essentials.warp I think, put them in globalgroups.yml under Builder and default

    Hehe, thats exactly what I need. I don't really like Essentials, or any other All-In-One-Pack. I like to build my own plugin list :D

    Hello, i've got a problem.

    Tekkit version: 2.1.0
    Bukkit version: 1.1-R4
    Operating System: Windows 7 (x86) Home Premium
    Version of Java: Java 7
    Description of Problem: Picaxes (and other tools ?) are disappearing when used for a short amount of time. There are no error logs on console or something. Anyone can tell how to prevent this?

    Using these plugins: SWatchdog, WorldEdit, Towny, Register, WorldSaver, Vault, Permissionsex, Questioner, WorldGuard, Essentials, ChatManager, AuthMe Permissions, Modifyworld, LWC, WorldBorder

    Error Messages:
    There are no error messages.

    Without bukkit plugins it doesn't break. I even tried to one plugin, remove it and add the other and etc and there were no pickaxes-bug. But when i turn on all plugins, booom.

    Thanks!

    I would suggest testing each plugin in hopes of pinpointing the culprit.

    Since you don't have too many plugins, this shouldn't be too tough a task - though it will be a bit rote and tedious.
    Start with no plugins and keep adding plugins, one-by-one, until you find the plugin that causes server mechanics to "break," as you put it.

    Then, after isolating the problematic plugin, remove it and check the plugin's thread. Optionally, notify the plugin dev. of the issue and they might fix it/make a work-a-round for Tekkit.

    Edit: Didn't see the part of your post where you said you tested plugins.
    Nonetheless, don't remove plugins when you test them. Just add plugins until you encounter the issue - don't add one plugin, remove it, and add another.

    There's probably some incompatibility between plugins - not necessarily Tekkit related, though it could be. Start with 0 plugins and add plugins (don't remove any!) until you encounter the plugin that seems to be responsible for the error.

    Removing that plugin should resolve your problem, but you could keep testing by starting with the first plugin you added and cumulatively removing plugins, until the problem disappears. This would indicate an incompatibility between two plugins.

    If you can't follow what I'm getting at (it's a bit convoluted, I know), I can try and clarify after you re-test like I've recommended.

    Post your permissions file on pastebin.com and provide us with a link if you want any accurate help.
    Also, please specify which permissions manager (permissions plugin) you are using.

    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

    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.

    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?

    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.

    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.

    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.

    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?
