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


And i kept getting a message


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.

Server :: OpenVPN Access Server Error: 501 Not Implemented

Apr 12, 2011

We're setting up an OpenVPN access server, a quite straight-forward and very customizable system. Only we have a problem, I guess caused by Apache, when we try to reach the client web server via a custom port (see screenshot in attachement) we get the following error: Code: 501 Not Implemented. The requested method is not implemented by this server. Although we have added on the cisco router a port forwarding for port number 9943. It is working when we access the website : port with the local IP address [URL]...

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 :: 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:
Openvpn server ip:
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 '' to '') 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
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 (, for example), instead of a static IP ( also thought to use a DHCP server, but I'm not sure that will work.

Ubuntu Networking :: OpenVPN / Adito Setup - Extranet Access

Feb 25, 2010

Alright, I've been trying to get this fixed on my own, but I think I am missing a fundamental principle and no amount of scripts or hacks is gonna take place of that. I have adito/OpenVPN installed on my media center. It runs fine and I can access adito in my internal network from other computers just fine. But, the whole point is I want to be able to access it remotely!

Now, I had previously made a run at an external FTP site and failed miserably at that, and I think its all coming down to me not knowing how to configure my own router. I have a Netgear router, I can log into it and under Router status I can get what looks to be my routers external IP address. But if I try to access it at https://XXX.XXX.XXX.XXX:4433 (didn't want to use the default port, 443) I get nothing.

So, my main problems as I understand them are:
1)I need to clear the firewall on my router to allow traffic in/out of my reserved port
2)I need to forward incoming requests on that port to the static internal IP of my media center
3)I really would like a more reliable way to verify the info im getting from my routers admin settings page is actually my external IP, is there a command for this or a website that will tell me?

Ubuntu Servers :: Access To Web Server Files ?

Jul 24, 2011

I'm new to Linux and have taken over at a company where the linux admin walked out. he has several older linux based servers running version 8.1 i tried running the command sudo apt-get install swat xinetd to setup swat but i get an error that it can't find the package. in addition, this directory xinetd is no where to be found under the etc directory. i've verified that samba is in fact installed on these servers but for some reason the xinetd and inetd directories are not on these servers.

Could it be possible that this older version of linux does not support Swat? i'm considering upgrading very soon to the latest but my main problem right now is i need to copy all web server html files that he had on the web Server i know there are different ways to copy files from linux systems but need the best way to copy all the files so none of the website links get broke off this linux server over to my windows server.

Since i don't have access to anything of the directories nor files on the web server, what is the best way to copy these files and folders off this server?

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...

Fedora Networking :: OpenVPN Client - How To Access Internal Ressources

Sep 26, 2009

I'm using Fedora Core 11 and the client OpenVPN on the network-manager into a segmented infrastructure. It works well.

My laptop is on a dmz wireless Zone and access Internet through a firewall via a front-end zone with wlan0 interface.

But my laptop can access on a back-end zone to a server.

When I start the OpenVPN tunnel, I cannot access on my back-end zone because the kernel routing table is modified (all the traffic is routed through the tun vpn interface)

If I define a static route like route add -host 192.168.2.x gw where x is my file serveur, I cannot connect to this server because the routing is make through the tun interface and not by the wlan0 who can access on is gateway

I want to know where changing the kernel routing table file to access on the Internet and on my back-end zone in a same time.

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 :: HTTP Throttling - Limit Access To My Web-server

Apr 12, 2010

I'm thinking about some ways to limit access to my web-server. It runs Nginx and php in FCGI. The server contains a large amount of information. The data is freely available and no authentication is required but other companies might like to mirror it and use on their own servers.

The requests could be limited on different levels: IP, TCP, HTTP (by nginx) or by the php application. I found some solutions (like Nginx's limit_req_zone directive), but they do not solve the second part of the problem: there's no way to define a whitelist of clients who are allowed to use the data.

I thought about an intellectual firewall that would limit the requests on IP basis, but I'm yet to find such device. Another way was to hack some scripts that would parse the log file every minute and modify the iptables to ban suspicious IPs. It would take days and I doubt this system will survive, say, 1000 requests per second.

Perhaps, some HTTP proxy, like Squid, could do this?

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):


# Setup
dev tap
port 5091

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