so you can stop and start the server remotely?

 

hey i love this plugin, but can you make please a possibility to save the user, password and ip in the udp client !? and a possibility to make the "console say" with the remote toolkit would be very nice too

 

ill still cant get this to work. ive tried and read carefully, perhaps a YouTube clip is in order.

 

Open the .bat in notepad and replace 'java' with:

Code:

"%ProgramFiles(x86)%\Java\jre6\bin\java.exe"

It is a known problem with bukkit. The wrapper should force a restart after about 5 minutes, but since I have not encountered that problem with bukkit before, I cannot verify anything.

Yes, that is one of its features.
And where are you stuck in the setup process?

I'll look into having the UDP client data persistent. I may add the ability to issue commands (like 'say') over UDP, but I am still split on that decision. For the mean time, you should be able to log into the console via telnet and issue 'say' commands that way.


@Fuzzwolf @virtualism What OS are you using? Also, how common is the problem and does it correct itself without restarting the wrapper?

 

I think that the Unknown Command is due to the periodic saves. The saves seem to work (as tested by an accidental server shutdown), yet they don't display a message besides "Unknown Command." I am using Windows 7. My plugins are:
Citizens
CommandBook
iConomy
iConomyChestShop
LWC
MagicCarpet
MineQuest
WorldEdit
WorldGuard

To the best of my knowledge, none of these plugins manipulate saves (I think ... ?).

 

Debian 6 64bit.
http://pastebin.com/mjVqRQNe
10 min, 10 times. Not been able to get rid of it. (With the timing, fuzzwolfs idea seems pretty reasonable )

 

@Fuzzwolf @virtualism What craftbukkit build are you using? Make sure the plugin component is up to date, and also try deleting the jar from the plugins folder.

I think it is more likely that it is a problem with the periodic heartbeats.

 

760. 766. Yeah, i did see your 740 in the title, but i was stubborn. I can't restart the server right now, but i remember from last time i stopped using it that the message disappeared. I'll try updating it to be sure and getting rid of it, and running it on a virginal server, once people go to bed and I won't have to deal with the moaning about five minutes downtime.

 

Would it be possible to add the ability to reboot the computer itself on a schedule like we currently can for the minecraft service. Or have the ability to shutdown the minecraft service completly and not restart? (I would then use window's scheduler for rebooting the machine).

I am currently running the server on a not too powerful machine but this is temporary. I have noticed that it has hard time after maybe a week of use. Minecraft is set to restart every mornings via your wrapper but seems like the computer would also needs to restart too for optimal performance. So either this could be done via your wrapper? or I would do it via window's scheduler service (but it would be best if minecraft would not be running when that happens, don't want to endup with corrupted data or things like that). I can at least set the reboot to happen just after minecraft has rebooted (it would have saved before the reboot) but still, ending minecraft improperly is not very recommended i guess.

Think you can have a solution?

Thanks!!

 

Hm, I am using 740 yet I still have the same issue. Virtualism, are you using any of the same plugins that I am using?

CommandBook
iConomy
iConomyChestShop
LWC
MagicCarpet
MineQuest
WorldEdit
WorldGuard

 

see above.

 

@Fuzzwolf @virtualism Your problem appears to be that the plugin component is not enabled.
Make sure that MinecraftRKitPlugin.jar is in the plugins directory of your server. Your problem is consistent with exactly what would happen if the wrapper attempted to send heartbeat requests if the plugin was not active.

 

umm sir there is an auto-save plugin, it's even called Auto-save.

 

That post was made months before this supported auto-saves, and before that other plugin even existed....

 

oh ok my bad

 

Love this plugin. absolutely awesome.

I do have a question though. Is there anyway that something like THIS could be added? basically, if someone tries to get into the server will its being held or is down, the RTK will display a message telling them to wait.

Also, are there any GUI modules for the RTK? if not, do you think that running THIS with the RTK would work?

Thanks again!

 

how do i enable my startup bat, i got

Code:

@ECHO OFF
IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="64" "%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1024M -jar "%~dp0craftbukkit-0.0.1-snapshot.jar"
IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="86"  java -Xincgc -Xmx1024M -jar "%~dp0craftbukkit-0.0.1-snapshot.jar"
PAUSE

when i start it this why the client doesnt connect. but when i use

@echo off
java -Xmx30M -Xms30M -XX:MaxPermSize=40M -jar Minecraft_RKit.jar ****:****

the client works, how do i add the rtoolkit.bat info to my customer server starter?

 

Get this quite often while server is on .hold, harmless?

java.io.IOException: Stream closed
at java.lang.ProcessBuilder$NullOutputStream.write(ProcessBuilder.java:434)
at java.iutputStream.write(OutputStream.java:116)
at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:82)
at java.io.BufferedOutputStream.flush(BufferedOutputStream.java:140)
at com.drdanick.McRKit.Wrapper$4.run(Wrapper.java:376)

 

My server randomly crashes and restarts with no error messages at all. :S

Gives the error "Internal exception: Java.net.SocketException: Connection reset by peer: socket write error" when it crashes and restarts.

 

I'm exploring the idea of having it send messages to people connecting to the server while held. It will likely be in a future update.
As for the GUI, i'm almost certain it could work. I cannot give any instruction until i've tested it myself, though.

I'm not sure about exactly how your custom server starter works, could you give me an idea?
If you wanted to, say, have it start with a similar .bat format to the other startup bat, you can use this code:

Code:

@ECHO OFF
IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="64" "%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1024M -jar "%~dp0Minecraft_RKit.jar USER:PASS"
IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="86"  java -Xincgc -Xmx1024M -jar "%~dp0Minecraft_RKit.jar USER:PASS"
PAUSE

That should be normal. I'll work on suppressing it in a future update.

That is a problem on Bukkit's end. It is restarting because either the server process crashed entirely, or it became unresponsive.

 

Awesome, thanks dude! I'll give it a try and let you know what happens.

 

Quick scenario! I run my server off an amazon micro instance, that seems to throttle my IO if it is overused. However, with this plugin, my server can run pretty smoothly if i disable minecrafts auto-save. Problem is that everytime the server restarts, i need to re-enter the command 'save-off' into the console or it will continue having lag spikes when it trys to save.

Anyone know how i can perminantly disable the minecraft auto-save and use this plugin to save instead?

 

trying to get this working with jrockit, but i get this error:

jrockit launches fine with this command

Code:

need to make changes to wrapper.properties in order to accomidate jrockit

Code:

input appreciated, thanks

 

Is there a command to see how long it is till the next restart?

 

Have not had much success with crash recovery, generally end up having to killall java.

Stuff like: http://pastie.org/1915687

Java just endlessly using CPU, never actually killing the server and restarting it.

 

For shame, Virtualism. Why do they let people like me administrate servers?

Thanks. :3

 

Guys how can i make it so everytime it does a world save, it does this:

/save-on
/save-all
/save-off


when you do a save-all while auto save is off, it doesnt work :S

 

Is there a way to STOP the server at like 19:00 instead of RESTARTING the server?

 

Working on a solution to that.

Ah, you didn't specify the jar file when you overrode the process arguments. Use the following config:

Code:

#Minecraft Remote Toolkit Properties File
#Tue May 17 16:17:19 SGT 2011
minecraft-server-jar=/home/minecraft/craftbukkit-0.0.1-SNAPSHOT.jar
severe-exception-detection-level=1
server-saveall-period=0
maximum-heap-size=
import-properties=false
server-restart-delay=03\:00
server-heartbeat-threshold=1m
restart-on-severe-exception=false
server-arguments=
overridden-process-arguments=/home/minecraft/jrockit-jdk1.6.0_24-R28.1.3-4.0.1/bin/java -Xms1024M  -Xmx1024M -Djline.terminal=jline.UnsupportedTerminal -jar /home/minecraft/craftbukkit-0.0.1-SNAPSHOT.jar
failed-heartbeat-restart-count=5
server-restart-alerts=10m,5m,1m
forced-restart-delay=5m
initial-heap-size=
extra-runtime-arguments=

That will be in the next update.

Did you issue the forced restart manually, or was it triggered automatically? When/if this happens again, note down how many java processes are running and the resources each is using.

I am currently working on that.

 

Great plugin/tool.

Just a quick questions - is there anyway to cancel a pending restart? (eg. scheduled restarts every 6 hours, server's running fine and players are in the middle of something - perhaps ".skipscheduledrestart").
