Server host/IP: mc.bywatercraft.co.uk /
Website name: bywatercraft.co.uk -/> bywatercraft.com

Currently the Bywater Craft Minecraft server is running Spigot 1.8.8. We have now updated the plugins to be compatible with 1.8.7.

Load Minecraft:

/usr/bin/java -Djline.terminal=jline.UnsupportedTerminal -client -Xmx7132M -jar spigot.jar nogui -d yyyy-MM-dd HH:mm:ss -nojline

Load McMyAdmin:

tmux new-session -n minecraft
cd /home/user
./MCMA2_Linux_x86_64 | tee yourminecraft.log

If you want to connect from elsewhere to view the above output/console load the screen session:

ssh user@localhost -pXXXX
tmux ls
tmux attach 0

To kill the process on boot:

ps -ef | grep tmux | grep -v grep | awk '{print $2}' | xargs kill -9

Using CTRL + D will quit screen and close any processes running within it.
To exit safely do CTRL + B, let go, then press D on it's own.

When downloading a backup from McMyAdmin, it comes in the mcb format. Change it to .zip and you can then unzip it into a folder and restore to the server.

Allowing PvP

Personally, for WorldGuard's pvp flag to work we had to ensure:

  • Essentials plugin had pvp = true
  • McMyAdmin control panel had Configuration > Game Settings > Allow Player vs Player combat
  • server.properties file had pvp = true
  • WorldGuard had __global__ set to pvp deny
  • WorldGuard then could have specific regions set to pvp allow


Reduce/downgrade Backpack space:

cd /Minecraft/plugins/Backpack/backpacks/world
ls -lah

Edit the value next to "contents-amount:" in the user's .yml file.

/tell PlayerName will whisper a message to a player. This option will not show in a console.

/msg PayerName will show it as YourPlayerName -> Me to the other Player but be private

Prefix and Suffix

Never use McMyAdmin's Prefix and Suffix boxes, as you likely will not be able to remove them after you have set them without removing the group and re-adding it.

Check server's TPS

Ticks Per Second

If you use Bukkit/Essentials, do /lag


If you add or remove a player to players.yml manually, keep a copy of the text you entered or of the file from which the text was removed. Sometimes when you do /color reload it will import an old version of the file from before the change you made. To resolve this:

  • make a copy of the text you added or the entire file not including the text you remove
  • run the following command:
:> players.yml
  • in config.yml set updateConfig: to true from the default of false
  • /color reload
  • now add or remove the text you did before, run the above command and it should work

Also, it may be worth keeping updateConfig: as true always

Colour and type

To use both colour and formatting/type such as bold, itallic, strikethrough and underline at the same time, use the colour first then the formatting:

amplified: '&6&oModerator&f'


/prefix me &6&oModerator

Command Block

Quick FAQ/Guide: http://hypixel.net/wiki/command-block/

Connection reset


Set opt-out to true in plugins/PluginMetrics/config.yml

This by default is false.

In minecraft.log "[INFO] Connection reset"

touch reset.sh ; chmod +x reset.sh ; vim reset.sh

netstat -pantu | grep -v LISTEN | grep 25565 >> reset.log
echo -e "\n-------------------------------------------------------------------------------------------"
date +%R
netstat -pantu | grep -v LISTEN | grep 25565

Then do the following in two separate SSH windows:

tail -f minecraft/install/directory/logs/minecraft.log
watch -n 1 ./reset.sh

Then match up the times, and block the IP address from the server list website that is causing the message:

iptables -A INPUT -s -j DROP
iptables -L



Allowing lava seems to be easiest by creating a group that can do it and then doing:

# Allow lava buckets

The below method seems to fail


Current errors

[WARNING] Can't keep up! Did the system time change, or is the server overloaded?

Current issues



To remove a map from rendering on the Dynamic Map web page, do this:

/dynmap pause all
/map mapdelete _worldname_:_mapname_

Or remove the folder from /home/user/Minecraft/plugins/dynmap/web/tiles/worldname

Configuring Maps and Worlds using dmap
Component Configuration

Render all:

/dynmap fullrender

Please be warned if you run a full render with the template set as the highest one for HD, hi_boost_xhi, then on a server with 8GB of RAM it will cause ~45-65% RAM usage.

Pause render:

/dynmap pause all

Start render:

/dynmap pause none

Disable world render:

/dmap worldset WorldName enabled:false

Hide a player:

/dynmap hide PlayerName

Show a player:

/dynmap show PlayerName



The Dynmap WorldGuard plugin that shows the WorldGuard region areas on the Dynamic Map shows a green border when there is no owner as it is not claimed.

This will stop a render in progress and purge the tiles.

/dynmap purgeworld Le_Monde

Modifyworld pass event

[SEVERE] Could not pass event InventoryClickEvent to Modifyworld v1.19.4 org.bukkit.event.EventException

Fix: Disable the Modifyworld plugin and allow people to edit the world via the essentials.build permission.

NoSplosion will cause Endermen to NOT spawn

Disables all explosions vanilla or mods (Tekkit etc...) and fire from destroying blocks as well as Endermen from spawning. All explosions and fire still damage players but do not damage the environment.

Your configuration might be outdated!

The best thing to do is just do:

mv config.yml old.config.yml

Then reload the server configuration or NCP plugin itself:

/ncp reload

Then check if the config is different:

diff config.yml old.config.yml

Install Feed The Beast on a Unix server

Add a user and make a directory specifically for the mod, e.g.:

add user ftb
mkdir server
cd /home/ftb/server
su ftb

Then do:

tmux new-session -n NameTheSession
su user
cd ~/server
wget http://www.creeperrepo.net/direct/FTB2/6ce418a51b200ece8cb3c509ba9e094a/modpacks%5EUltimate%5E1_0_1%5EUltimate_Server.zip
mv modpacks^Ultimate^1_0_1^Ultimate_Server.zip Ultimate_Server.zip
unzip Ultimate_Server.zip
vim ServerStart.sh

Edit the values as you see fit.

chmod +x ServerStart.sh
./ServerStart.sh | tee ftb.log

It will error out if you're already running a Minecraft server on the default port 25565. If it does, do CTRL + C. To change this,

vim server.properties

Set the server-port to something that is not 25565. Then make sure the user:group ownership is correct on the server folder and all files and directories below it.

./ServerStart.sh | tee ftb.log

CTRL + B then d to quit the tmux session.


If you get something like below, you likely need to disable some mods (for me it was mods/railcraft.jar and mods/MineFactoryReloaded.jar):

[SEVERE] [ForgeModLoader] Detected leaking worlds in memory. There are 4 worlds that appear to be persisting.
A mod is likely caching the world incorrectly

2013-04-23 15:54:59 [SEVERE] [ForgeModLoader] The world 3e6abeb4 (world) has leaked.

Install Votifier

Install the plugin as normal by placing the .jar file in your plugins folder: http://dev.bukkit.org/server-mods/votifier

Then reload the server and do:

cat plugins/Votifier/rsa/public.key

Copy the code into the area of the server listing website you are using.


SimpleVoteListener can perform commands and broadcast messages

Load MCMyAdmin and Minecraft on server start

ssh -p port user@localhost
crontab -e

Press insert and add:

@reboot screen -dmS minecraft /home/mc/MCMA2_Linux_x86_64

Then do:


You can then if you wish do:

touch /etc/init.d/minecraftd ; chown user:user /etc/init.d/minecraftd
vim /etc/init.d/minecraftd

Lock chests

Use LWC or Lockette.

To reload LWC, do /lwc admin reload

To snoop in a chest with Lockette and to do this without a broadcast message, edit this file:


And edit the following:

allow-admin-snoop: true
broadcast-snoop-target: ''

Kill all MCMA processes

ps aux|grep MC|grep x86|awk {'print $2'}

Results of the above command.

for a in `!!`
for a in `ps aux|grep MC|grep x86|awk {'print $2'}`
> do
> kill -9 $a
> done
ps aux|grep MC|grep x86|awk {'print $2'}


Migrate from one *nix server to another

scp / rsync the data in the Minecraft directory across. Then do:

apt-get install unzip
apt-get install openjdk-7-jre openjdk-7-jdk
cd /usr/local
wget http://mcmyadmin.com/Downloads/etc.zip
unzip etc.zip

Go to serverIPaddress:8080 in your browser. To login, check the details in McMyAdmin.conf. To change the password you need to stop McMyAdmin:

/quit in console

The file stores the password as MD5, to convert your password use this: http://www.md5hashgenerator.com/index.php

Remote Toolkit

Colour code errors in console/log such as:

[12:21:32 INFO]: CONSOLE: Forcing save..←[m
[12:21:32 INFO]: CONSOLE: Save complete.←[m
:32 INFO]: ←[0;35;1m[Server←[0;35;1m] Save is complete.←[m

This is due to the MinecraftRKitPlugin.jar file in your plugins folder. This is as of Release 10, Alpha 15.3 of the toolkit wrapper and happens on both Windows (example) and Unix (my own) (example 2).

Restart required

If you use PermissionsBukkit with McMyAdmin, if you make a change you normally need to restart the Minecraft server to get it to see the changes.

A huge advantage of setting the Permissions Export to PermissionsEx is when a permission is added to McMyAdmin it automatically reloads the configuration, this is shown in the console by:

[INFO] Permissions file successfully reloaded
[INFO] Permissions reloaded

If you op or de-op a player from ops.txt and the Administrators group in McMyAdmin.

To set negative permissions in PermissionsEx, use - -permission before the other permissions.

Restore backup from McMyAdmin

cp -v world world_nether world_the_end BACKUPOFWORLDShhmm/ -R
mkdir movedawayworlds
mv world world_nether world_the_end movedawayworlds

Then restore the backup via the McMyAdmin control panel.


To check when a player was last online, their IP address, what world they are in, do:

/seen playername


screen -xr mcmonitor
screen -xr mysqlmcmon

cd /home/mc/Minecraft
cat server.log | grep "YYYY-MM-DD" | grep User | grep -v indestructible
cat server.log | grep User | grep -v 'indestructible\|fell from a high place'

Create the database:

mysql -p
create database hawkeye;
show databases;
use hawkeye
show tables;

This may be empty. If so (more than likely), log into your minecraft server and do /reload. Then go back into MySQL:

use hawkeye
show tables;
| Tables_in_hawkeye       |
| hawk_players            |
| hawk_worlds             |
| hawkeye                 |
select * from hawk_players;
select * from hawk_worlds;
select * from hawkeye;

And you can now do /hawk in game. To check a block, do /hawk tool , then left click a block and it will show you the block information.

Get table structure and players

desc hawkeye; select * from hawk_players;

Look at logs

Via a web interface: http://dev.bukkit.org/bukkit-plugins/hawkeye-reload/pages/web-interface-setup/

If you do a search and get this error message you need to re-download the interface:

Error! Unknown column 'date' in 'where clause'

Via SQL:

select * from hawkeye ORDER BY data_id DESC LIMIT 100000;

/region info area

It should output something like:

server.properties file

Set flyspeed

Default is 1

For yourself:

/flyspeeed 2

For others:

/flyspeed 2 playername

Setting spawn

On Bywater Craft where we have multiple spawn plugins, to set spawn you need to do:

/mw setspawn

Set warps

/setwarp NewWarpName

Go to warps:

/warp WarpName

List warps:


If you have per-warp-permission set to true in the config.yml then you can limit what warps players can use. This also controls what players would see with /warp, hence why both essentials.warp and essentials.warp.list are used.

Set world for SkyGridMP

vim SkyGrid.jar/config.yml

Edit this line:

Spigot patching 09/09/14 - 28/11/14 (old)

This was changed as of November 28th 2014: http://www.spigotmc.org/threads/bukkit-craftbukkit-spigot-1-8.36598/

Please now use http://www.spigotmc.org/threads/buildtools-updates-information.42865/ for Minecraft 1.8+

cd ~/spigotwork
java -jar ~/spigotwork/SpigotPatcher-1.0.jar ~/spigotwork/spigot1649.jar ~/spigotwork/spigot-YYYYMMDDa.bps ~/spigotwork/spigot-patched.jar ; mv spigot-patched.jar spigot.jar ; chown user:user spigot.jar

Using it


Update CraftBukkit

Stop the server, then do:

mv craftbukkit.jar versioncraftbukkit.jar
wget http://dl.bukkit.org/latest-rb/craftbukkit.jar

Or download the development/beta build and do:

mv craftbukkit-dev.jar craftbukkit.jar

Start the server

Log out and back into MCMyAdmin.

World Edit

Place .schematic files in /home/user/Minecraft/plugins/WorldEdit/schematics

Import them by doing:

//schematic load filename

Then you can do //paste in Minecraft to paste it into the world where you are.

Fill an area


Select position 1 and 2. Then do:

//set block

Unbind a tool/block

If for example you accidentally do //fill block (e.g. sand), and each time you right click with a tool/block or your hand, clear it by doing:


World Guard



To protect an area, do:


Then click the first position then the second position with the wooden axe.

If you only do one layer, you can do //expand to go up or down, e.g.:

//expand UpValue DownValue up
//expand 10 0 up

This would expand up 10 blocks from the single layer but do 0 down.

Then do:

/region define newnameforarea owner

Owner can be left blank.

To get information on the area you just created, do:

/region info newnameforarea

Allow fire spread/tick

In config.yml:

Set high-frequency-flags to true
Set disable-all-fire-spread to false

/rg flag __global__ fire-spread allow
/rg flag __global__ lava-fire allow

If this still doesn't work, if you have Essentials then set these in config.yml:

fire-spread: true
lava-fire-spread: true
flint-fire: true

Edit world regions from outside (and inside) that world

/rg flag -w ExactWorldName RegionName FlagName allow

If you want to use the blocked-cmds flag and want to block multiple commands separate them by commas:

/rg flag -w world MyHome blocked-cmds /tp,/warp

Entry flag for groups

Due to inheritance

/rg flag chestroomdoor entry deny
/rg flag chestroomdoor entry -g nonmembers
/rg addmember chestroomdoor g:citizen

This gets round inheritance by denying all except members from a certain group up the inheritance tree.

Let's say you have:

Region name: doorway
Group name: vip
Flag: entry deny

/region define doorway
/region flag doorway entry deny
/region addmember doorway g:vip
/region flag doorway entry -g nonmembers

This would stop entry to everyone who is not in the vip group for the doorway.

Region name: doorway
Group name: guest
Flag: entry deny

/region define doorway
/region flag doorway entry deny
/region addmember doorway g:guest
/region flag doorway entry -g members

This would stop entry to everyone who is in the members field, guest in this case, group for the doorway. Everyone else would be allowed.

Then you'd add the permission node "group.guest" to the guest group in your permissions plugin's config.

"Guest" isn't a group - http://wiki.sk89q.com/wiki/WorldGuard/Regions/Flags#Group


/rg removemember chestroomdoor playername

Group inheritance

Important note about the below example:

/rg flag regionname entry deny
/rg addmember regionname g:groupname

These two commands should deny entry to groups not added as members or owners.

Keep in mind that if you use any inheritance system in your permissions (for example: builder inherits default permissions), any groups that inherit the same permissions as the allowed group will also be allowed entrance to the region.

Your best bet is to eliminate the inheritances and give each group their own group.groupname permission. This allows worldguard to see separate groups.

The same goes with the exit flag.

Flint & Steel doesn't work

If it returns the message:

You're not allowed to use that here

Do this in-game:

/region flag -w world __global__ lighter allow

Source: http://forums.bukkit.org/threads/i-need-help-with-allowing-flint-steel.152990/

Rename region

You cannot do this without editing the database manually. If the area is not too big, just remove it and re-add it.

If you do edit the entry in the id column of the region table of the worldguard (by default) database, just do /worldguard reload in-game after you have changed it.

Set flags

To set flags, see this page: http://wiki.sk89q.com/wiki/WorldGuard/Regions/Flags

To stop building and PvP but to allow use, you would do:

/rg flag areaname build deny
/rg flag areaname pvp deny
/rg flag areaname use allow

WorldGuard Block Restricter

This requires WorldGuard Custom Flags installing too.

To only allow a specific type of block you need to:

  • set build allow in WorldGuard: /rg flag areaname build allow
  • then deny all blocks via WorldGuard Block Restricter using /rg flag areaname deny-blocks any
  • then allow the blocks you want via WorldGuard Block Restricter using /rg flag areaname allow-blocks dirt
