Ubuntu Servers :: Minecraft Server - On Debian PPC - How To Use Openvpn

Mar 21, 2011

I recently loaded up my old powermac g3 with debian 6.0 PPC, and it seems to be running quite good. I control it using ssh from my windows 7 box. I installed default-jre, so I could run the minecraft server on there.

I've got two questions: I installed Openvpn, but I'm a bit confused on how to use it.. I want people to be able to connect to my vpn network over the internet, what configuration should I use, and could someone maybe link me a decent step by step tutorial?

secondly, when I tried to launch the server, it tried to generate a new map, but this is taking ages! on my desktop computer, it only took two seconds, but after over half an hour, it only got to 20% of "preparing spawn area" what could be wrong with this? Any reason why the java virtual machine would have performance issues? I have no clue.. I haven't tried copying over my smp map from my windows box yet, and launching that.. but I doubt performance will be any better. (my windows 7 machine is hosting at the moment for about 10 people)

Ubuntu Servers :: OpenVPN - Script Up/down - Access Server

Feb 24, 2011

I have a few issues after setting up Openvpn. At work i just setup a new Ubuntu Server 10.4. The server itself is working Great. I ended up getting Openvpn installed and working to a point. I have searched online and done as much reading as i could find but i keep running into the problem of not understanding. So here is the problem.

The server is set on a static IP address. At first i tried to have the config file listen on a virtual ip address i setup up in /etc/network/interface but that ended up not working so i set it to its specific ip address. I kept running into the error about script security while trying to start Openvpn. I tried to add into the config file "script-security 2" that way the up.sh and down.sh scripts were allowed to be run. That didn't help and then i kept trying to run Openvpn manually running the command

Quote:

And i kept getting a message

Quote:

So what i did was just comment out the "up" and "down" scripts in the config file. This allowed me to actually get Openvpn started on the server. So once this was done i connected form a client machine and was given an ip address like i should. The only issue is that i was not able to actually comunicate with the server. I have a samba share on there to allow me to copy files back and forth but an not able to actually communicate with the server at all. I should note that this is a web server that i can view from the outside. (actually get to the webpage) but i tried to access the website and share via the Openvpn gateway. I also tried to access the website portion using the hostname with no luck.

By the way, prior to putting the server on its separate network i was able to access the webpage and the samba share using both the ip address and the hostname.

Ubuntu Servers :: Setup An OpenVPN Server In Bridged Mode?

Jan 17, 2011

I am trying to setup an OpenVPN server in bridged mode (Ubuntu 10.04 Lts). The goal is for the clients to be able to reach all the servers behind Openvpn server's lan. I have followed the official OpenVPN guide for Ubuntu 10.04.

My network setup is:

Private lan: 10.90.90.0-255 255.255.255.0
Gateway: 10.90.90.1
Openvpn server ip: 10.90.90.8
Gateway public ip: 79.xxxxxxxxx

I have forward port 1195 to the Vpn server through my gateway firewall.Besides that no other firewall is running.I can connect and ping the server both from windows and ubuntu clients. The difference is that from windows I can reach the private lan but not from ubuntu clients.

Server :: OpenVPN Range Address / When Change Static IP To Dynamic IP In Config File OpenVPN Didn't Work?

Feb 13, 2010

I want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.

So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.

Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.

Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.

Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.

I hope I explained my problem as well.

My configuration file:

# OpenVPN Server Configuration File
dev tun 0
ifconfig 192.168.0.1 192.168.0.2
cd /etc/openvpn
secret key_file

In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.

Debian :: Cannot Connect To OpenVPN Server

Oct 20, 2015

I try to establish basic connection between my 2 end systems using openvpn. The problem is when i move the client files to my laptop i cant even ping the server from there. I copy paste the server commands in section 4 [URL] ....

In the client i ran the first command and changing VPNSERVER IP with 10.9.8.1 and LOCALGATEWAY IP with 192.168.1.1
which i thought that whats the server use : ROUTE_GATEWAY 192.168.1.1/255.255.255.0 in the server initialization process

The second command produce error device tun0 not found and when i create one using openvpn --mktun --dev tun

I get RTNETLINK answers : network is unreachable

Note : I use wireless connection in the client system (laptop). The server works good and i could ping him ( from the same machine ) but cant ping him or access the vpn server in my laptop. I also use default openvpn settings...

Networking :: Setting Up A VPN With OpenVPN On A Debian Lenny Server?

Sep 9, 2010

I'm setting up a VPN with openVPN on a debian lenny server. I successfully installed it in the server, then created the certificates and both client (winXP) and server config files. For the client I use openVPN gui. I tested the tunnel and everything went just fine. I even can ping the openVPN server from the XP client.But thats all. I can't ping any machine behind the openvpn server.Some facts that you may find useful to help me with this issue are:

- The openVPN server is not the default gateway of the LAN. The dg is a pfsense server
- I dont have iptables enabled (policy of all chains are ACCEPT).
- I have configured ip forwarding (echo "1" >/proc/sys/net/ipv4/ip_forward)

[code]....

I have checked and all seems to be OK. I think that the problem is connected with routing the traffic from the vpn to my LAN but I don't know how to do that (besides the push route line in the server.conf).

Ubuntu :: How To Fully Automate A Minecraft Server

Jun 29, 2011

I'm trying to fully automate a Minecraft server, and I decided to use Ubuntu 11.04 on this computer. The computer I'm using for it is an old computer (it's the old family PC, it's about 5 years old (and running amazingly now that I've formatted the hard drive (compared to how it used to run))) so it won't run the Unix environment (or something like that) and runs the Gnome environment instead.

Anyways; the server auto-starts when my computer turns on (my computer also automatically turns on). Now all I need to do is have my computer auto-shutdown at 12:00AM as well as enter the command "stop" into the running terminal. I plan to later add more commands (such as automatically welcoming people to the server when they connect, but that's not important right now and I'll likely be able to figure out if I can get this working).

This is the command I'm using to shutdown the computer:

sudo shutdown -P 24:00

However, it doesn't work. First of all, I need to enter my password, so I need some way to have the shell file enter my password for me whenever the terminal asks for it. Second of all, it just plan doesn't work, even if I enter my password (like, the countdown doesn't appear). As for entering commands into the terminal, the only way I can think of is:echo "stop" But the problem is that doesn't work because it wont enter into the running terminal (and I don't know how to do that).

Debian :: Why To Have To Use Root To Play Minecraft

Jan 10, 2016

I can run Minecraft if I log in to su but I have a user to whom I do not wish to give su permission. If I try to run Minecraft from the terminal without signing into su first, I get a lot of error messages that I do not understand. I think it might have something to do with having to give the user permission to run java but I am not sure.

Here is the output:

Current time is Jan 9, 2016 5:31:46 PM
System.getProperty('os.name') == 'Linux'

Debian Multimedia :: Increasing And Decreasing Screen Brightness Crashes Minecraft

May 3, 2015

When increasing or decreasing the screen brightness, Minecraft crashes and to an extent freezes my computer UI. What I mean by to an extent is that I can move the cursor around, but I can't click on anything. I can also run keyboard shortcuts and type, which is how I restore my system by terminating all java processes with pkill.

What causes minecraft to crash and how can I solve it?

Ubuntu Servers :: OpenVPN Slow When Windows Is Used ?

May 16, 2010

I have many openvpn implementations. Every time I use windows shares over openvpn, the speed is no more than 500KB/s, in LAN environment. When I start a copy it reaches 200-300KB/s, when I start second one it reaches 500KB/s. No more is reached after more copies simultaneously. When I use linux to copy files - the first copy reaches 700KB/s, the second copy reaches 2.5MB/s (then the first grows also to 2.5MB/s), the third copy reaches also 2.5MB/s. All of these are copied simultaneously, otherwise when only one is started it sits on 700KB/s. Moreover when 2 of the 3 simultaneous copy processes end, the one left backs at 700KB/s again.

But this is linux. When I use Windows the transfer speed is no more than 400-500KB/s (LAN environment).
The OpenVPN server is always ubuntu (any version - I've tried 6.06, 8.04, 10.04).

Tried the OpenVPN client in ubuntu (and the windows machine behind the ubuntu), in windows (directly installed the client on windows) and it is all the same - no more than 500KB/s.

I can not use this because it is so slooow. When only one file is copied at a time it reaches only 200KB/s!!! Searched all the google results - no one have an answer, although there are many people with the same problem.

Now, I am sure that the problem is in Windows, because when I use linux as a server and as a client, the client copies fast. But when I use windows as machine behind the client it copies slow. I don't know... something in the tcp/ip settings in windows or something...

Ubuntu Servers :: Portable OpenVPN Without Admin Rights?

Feb 4, 2011

I have OpenVPN setup and running on my home server (Lucid Lynx). I move around alot and use Portable OpenVPN to connect to my home server. The problem is a lot of the computers I use I do not have admin rights to install the necessary routes to connect. So my question is this. Can OpenVPN be configured to use PPTP protocol? Because I have PortableVPN on my U3 flash drive and that VPN client does not need admin rights to run. If OpenVPN cannot do this, and from my understanding of its archetecture it cannot, but I must admit i am no authority on the matter. Can you suggest a workable solution, ie. install and setup this server software and use this portable client software.

Ubuntu Servers :: Webserver On OpenVPN Client (visible To Internet)

Apr 19, 2010

I'm trying to run Web server (nginx, does not really matter) "behind" VPN tunnel (i.e., on VPN client - the idea is that Web server is available at VPN endpoint IP on VPN server). Stock Ubuntu 9.10 Server with stock openvpn 2.1. No network changes done, only ufw is enabled and IPv6 is switched off. I need this box to be available at main IP address, no default route for VPN tunnel.

Tunnel itself works nicely, no problems at all. Hand-made static routes work via tunnel just fine. Problem is in-going traffic - I can see that it at least comes via tunnel (via OpenVPN debug), but is blocked (or dropped) by firewall or kernel. As far as I know, specific VPN server does not filter anything and is used for running Web servers on other IPs. I think I might need to set up some sort of IP forwarding for tap0 device to localhost - but don't really know where to start.

Tried disabling firewall, making Web server listen on all IPs (from localhost to VPN tunnel) - no luck. The box is in another country and KVM will be time and money, so I really don't feel like experimenting. openvpn.conf (IPs are obscured, non-relevant options removed, based on recommended config for that server):

Code:

# Setup
dev tap
remote 1.2.3.4
port 5091

Ubuntu Servers :: Setting Up A Bridge For OpenVPN / Tunnel All The Traffic Through The VPS?

Fedora Servers :: OpenVPN Setup On FC12 - Ethernet Ports?

I am trying to setup a VPN on my FC 12 box. Looks like getting openvpn to work behind NAT is as easy as just forwarding the ports. Do I need to forward any specific protocols (GRE, etc)? Also, can I do this with one Ethernet port (IE: RJ-45 jack), or do you recommend a second ethernet port? I could add in another PCI ethernet card if it makes it easier. Anyone know if a single ethernet jack will work or do I need two?
