Fedora 14 + java + Minecraft = help please.

[Lloyd5867]

Okay, so I can get it to run, I can get the server to run, I can get the java to install. My purpose is to run a server off it in VB. The server runs fine, I'm okay with the command line coding, the problem I am having is accessing the server. The internet runs slow, I can get it to run on NAT and Bridged but no others. No one on the LAN can access even though the router is forwarded and VB (when in NAT) is forwarded as well.


I don't understand why I can't access it.

I have read 90% of the guide for VB, and have read and reread the networking and still can't access it from the outside, I have also tried uninstalling and reinstalling according to the installation section


Like I stated above, all I want to do is run a server off it. I can manually install java to run the server and get the client itself to run but if I use the Yum install method like the guide at fedorafaq.org says then it doesn't work. I don't need fedora to be completely setup, just enough to run the server. I am open to other versions of Linux to run it. linux runs smoother and has better resourcing than windows.

My current rig:
Phenom II X4 955 BE
8 gb 1333mhz Corsair Ram
GeForce GT 430 1gb
WD 320gb 7200 rpm drive blue
WD 500gb 5400 rpm green

Look at this logically. Where is the defect? Try ping and tracert to find where the connection is failing.
What about the firewall in the host? If you want the easiest way for the LAN to see the server then use Bridged mode. NAT will require port forwarding on the host and not just the router.

[Lloyd5867]

I pinged and traceroute, nothing is blocked. I went so far as to activate the bridged connection to DMZ mode disabling the routers firewall entirely. the firewall I run, Comodo, hasn't blocked any incoming or outgoing connections. Even so I have now allowed all things VB through the firewall, testing now.

[Lloyd5867]

that didn't work either. Would a different version of Linux be more compatible, or maybe a server version of linux?

[Perryg]

Fedora works just fine. You can try a different one if you like though but I doubt it will change anything.
Disable comodo and the Windows firewall to start with and make sure that it is not blocking the connection.
Start by making sure that the service is actually working on the guest first then try the host and then the LAN.
Never use 127.0.0.1 as the connection IP as this is the local loopback on any PC that has a network. Use the assigned IP address (preferable fixed and not static)

[Lloyd5867]

Shut down firewalls and antivirus ran the trace route again reinstalled and re setup java and the server still cannot connect. ping and trace both 10ms bounce. internet is faster since reinstall.

can't even access it over my internet IP. Do you think it could be my router?

or possibly the port is different on the VB than it should be on my host. but I don't think that make sense, because the router should just route to the ip, it shows up as linux under my router and has its own lan IP.

I just don't get it.....is there some command I need to run in the terminal that involves vb commands?

the ones in the guide crashed the net in the box its self even with guest additions installed....this is just a conundrum...

[Lloyd5867]

Okay, since I have still gotten no reply, I decided to try and use Ubuntu Server. I was using a guide hoping that if I could use this tried and proven guide, and was able to at least access the webserver through virtual box that I would be able to access minecraft. No luck.


What I don't understand is that I am able to access the server when running it in a windows 7 environment through VB. using all the same settings, and with any of the network adapters.

It must be the way the Mindcraft server is setup. Have you checked with the Mindcraft people?
See http://www.minecraftwiki.net/wiki/Tutor ... structions on how to set it up in case you have not already found this.
It seems very detailed and from the looks of it you need to verify that everything is set up properly.

If you use Bridged mode and can actually reach the Linux guest from the host then VirtualBox is out of the picture. It must be a setup issue, especially if the guest can reach the outside world and you can ping the guest from the host.

[Lloyd5867]

Well I gave up on it for now, I found a way to run it on my computer without it lagging.


but more on the issue incase someone else runs into. I could connect inside the guest to the server, I could ping the server on that port, I just couldnt connect to anything. I could run and connect to the server in a windows guest. I did use the minecraftwiki guide to set it up as well. and followed the guide for installing java.

In Fedora the minecraft server might still be blocked by iptables or even selinux could prevent connection from outside.

Edit: Just tried it myself and I only had to add port 25565 (standard minecraft server port) to fedora's firewall settings.
And the server itself worked with OpenJDK
