How do I port forward correctly?

Hi,

ok, it seems you are using an older java. On the SL 6.2 box I'm using

java-1.6.0-openjdk-1.6.0.0-1.49.1.11.4.el6_3.x86_64

So, please install this package. Eg

Code:

yum install java-1.6.0-openjdk-1.6.0.0-1.49.1.11.4.el6_3.x86_64

Then check that /etc/alternatives/java links to the new version. Ie if you run the following command you should get the same output

Code:

% ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 46 Sep  6 04:08 /etc/alternatives/java -> /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java

Once you've done this try running the minecraft server again.

No feedback when I tried to start it, it's in the files though

Hi,

in [code] blocks in my post, if there is a "%" on the line it indicates that this is a command that I ran (or want you to run) at the prompt.
If there is no "%" this means that the text is the output I got. So the command that I want you to run is actually "ls -l /etc/alternatives/java".
This is just to confirm that when you run "java" you will actually be running the newly installed version.

I also wonder if this is also the reason you got no output when running "readlink -f $(which java)".

Hi,

you entered the "%" in the command again. Just enter "ls -l /etc/alternatives/java".

Sorry didn't notice

Code:

[root@metroville ~]# ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 46 Sep  5 20:56 /etc/alternatives/java -> /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java

Bump?

What is your question?

We never answered how to port forward yet :P

evo2 · 09-10-2012, 06:13 PM

Hi,

I thought the port forwarding question was based around a misunderstanding of the error messages produced when using an older (incompatible) version of java.

So, could you restate the question?

Alright, how do I open port 25565

evo2 · 09-10-2012, 07:51 PM

Hi,

why do you think it needs to be opened? Are you unable to connect to your minecraft server?

Are you running some sort of firewall?

Well I can't even start the server, this is what happens

Code:

m
[minecraft@metroville ~]$ java -Xms384M -Xmx384M -jar craftbukkit.jar nogui
[minecraft@metroville ~]$ cd Metroville
[minecraft@metroville Metroville]$ java -Xms384M -Xmx384M -jar craftbukkit.jar nogui
[minecraft@metroville Metroville]$ java -Xms384M -Xmx384M -jar craftbukkit.jar nogui

evo2 · 09-10-2012, 08:20 PM

Hi,

can you please go back to the standard minecraft server? As I think I explained earlier it is *much* easier to troubleshoot things when there are fewer unknowns.
