Java application needs sudo

[risegeek]

I am running a minecraft server - I have read many tutorials on how to get it running and it works perfect :) however I have not seen anyone with this problem. I need to run this with sudo or it will give errors.

I am stuck here guys :(

You appear to be running "minecraft.jar" from a place you don't have permission to write to, hence "java.io.FileNotFoundException: server.log (Permission denied)".

The "server.log" file will be created in the same directory as the jar file.
Copy minecraft.jar to your home folder, then try running it.

You don't have access to server.log file. change file attributes if you can or move the file to ~.

"java.io.FileNotFoundException" - the file doesn't exist.
Minecraft server creates the file on startup, along with any other files it needs, that don't exist currently.

I've moved it to my home directory, same problem. These files do exist I believe;


sam@server1:/home/minecraft$ ls
banned-ips.txt Minecraft-Overviewer server.log.1 util.py
banned-players.txt minecraft_server.jar server.log.lck util.pyc
blockcounter.py nbt.py server.properties world
chunk.py nbt.pyc setup.py world2
chunk.pyc ops.txt template.html world.py
COPYING.txt quadtree.py terrain.png world.pyc
flatgrass quadtree.pyc textures
gmap.py README.rst textures.py
minecraft.jar server.log textures.pyc


Sorry for the file cluster, I was fooling around with overviewer y/day.

I HAVE THE SOLUTION YOU ARE LOOKING FOR!!!
had the same problem and now it works perfectly

btw NEVER RUN THE GAME SERVER AS ROOT OR SUDO IT.. bad bad


go to the folder where the minecraft server is and run this command

sudo chmod -R 0777 *

I am having the same issue, the above did not fix the problem.

Can you please go through and describe your problem, perhapse past the log you get from trying to run the minecraft server so that I can see what would be the problem?
