Ubuntu Security :: Can't Seem To Activate The Openvpn Server In The Gui?

Aug 4, 2010

I installed OpenVPN and gadmin-openvpn-server from the repos and I can't seem to activate the openvpn server in the gui. I have the server certificate generated, and all the information on encryption protocols setup, and accounts named and ready, despite accounts that were already there, such as www-data, bind, ossec, etc being listed. The server log states:

PLUGIN_INIT: could not load plugin shared object /usr/lib/openvpn-pam-auth.so: /usr/lib/openvpn/openvpn-pam-auth.so: cannot open shared object file: No such file or directory.

Software :: Gadmin-openvpn-client Won't Activate Connection / Fix It?

Jan 19, 2011

I can get a tunnel connected via terminal with: openvpn --config client.ovpn

However, when I tried to use the "friedly" gui (gadmin-openvpn-client), it keeps telling me to "import server certificates into client first."

I don't know what that means. Nor, do I see a tun device.

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.

Security :: Security Of OpenVPN With Premade Keys?

Jan 2, 2010

Im a total beginner when it comes cryptography and networking. Finally managed to create a connection with OpenVPN on Ubuntu to a vpn provider called ivacy. On this page:http://ivacy.com/en/doc/user/setup/winxp_openvpn they give configuration files and keys, which I used. The question is, if someone wanted to see my network traffic, could they do it using the keys provided on that page. Reading the OpenVPN documentation i saw that it is also possible to create your own keys. Would that be more secure?

Security :: OpenVPN Security For Clients?

Jan 8, 2010

I have a running proxy server that I wish to also turn into a VPN server.The VPN is not used so much that a user can access the network but is used so that they can obtain a geo specific IP address for their applications (the proxy server only does this for HTTP).I would therefore like to block off the VPN from accessing any of my Linux box's ports such as email, web server etc.Clients are given local IPs of 172.16.0.x.What should I take into consideration to block off clients from accessing dangerous stuff on the network?

Ubuntu Security :: Openvpn Won't Work On A New Network?

Jan 5, 2010

A couple of weeks ago I was using openvpn with a provider of PVNs on a home wifi network with no problems.I had installed openvpn using apt-get install and downloaded theopvn PVN files from the organization.erything worked fine.I would type sudo openvpn nameoffile.ovpn and then add my username and password during the installation process.However, when I try to do the same on an Ethernet network, the installation work fines (as above) and informs me that everything is connected (same as on the home Wifi network) but Firefox and all other software cannot connect to anything on the Internet.I contacted the organization who said the DNS was a problem and I needed to install resolvconf then modify each .opvn file using up /etc/openvpn/update-resolv-conf and down /etc/openvpn/update-resolv-confcauses the installation to hang because it does not like openvpn pointing to an external file.Irrespective of the problem I have with this "solution", previously I could use openvpn without modifying the .ovpn files. It just worked! I wonder if anyone knows why using the exact same configuration on an Ethernet network (which I have not used before with openvpn) is causing problems

Ubuntu Security :: Configuring Iptables To Allow VNC And OpenVPN?

Jun 20, 2010

I'm running Ubuntu 10.04 LTS as a VM in Hyper-V, and accessing it via VNC with a machine in the same broadcast domain. I'm using OpenVPN to connect to XeroBank. I have instructions for configuring iptables to permit establishing and using the XeroBank connection, while blocking all other traffic on eth0. I've followed them successfully. I need to also permit the VNC connection, and haven't managed that. FWIW, the VM is at 192.168.111.12::5900 and the workstation is 192.168.111.2.

The attachment to this post lists the recommended contents for each Shorewall file. Which files need changed, and what do I add to each?

Ubuntu Security :: OpenVPN Installation Using Apt - Components

I just installed OpenVPN using apt, and it doesn't seem to have components which are distributed with the source, such as easy-rsa. Why would tools like this be excluded from the package? I prefer to use apt rather than compiling from source, to keep things neat and simple.

Ubuntu Security :: OpenVPN Connects To VPN But No Internet (10.10 64-bit)

Jan 5, 2011

I use vpntunnel.se and followed their tutorial for OpenVPN and it connects and assigns an IP. However, once the sequence is initiated and I open my browser I cannot connect to a webpage and get a "cannot resolve" error. I e-mailed their support and they suggested I change the DNS of my network settings. I did that but the same problem. Once I close OpenVPN my internet works again. It works in windows, so I know it is not my router...I use a wireless connection with my router. I don't know if this has something to do with anything...

Ubuntu Security :: Get Openvpn Start-up Script To Ask For A Password?

Jul 20, 2011

I have to say, I'm a little astonished at how anxious people are to bypass password checks on networks, all for the convenience of having things come up automatically. But given the world as we find it, I'm seeking a different approach.

I have an OpenVPN network. It works fine, but for my laptop, I've selected a client certificate that requires a password, so that if it falls into nefarious hands, the thief will not have immediate access to the VPN.

I'm trying not to have any data at all on the laptop (yes, a waste of a 500GB drive). So I want the VPN up even before I log in through the GUI.

It would be nice if the boot-up sequence would pause for the openvpn start script to ask for this password. I see the script contains a line "# X-Interactive: true" which I understand from documentation is supposed to accomplish this. But it doesn't. OpenVPN simply fails to start, which is better than the alternative, but a pain.

I have already disabled the splash screen (having been around Linux for over ten years, I am more comfortable seeing boot-up messages anyway, though even on this x86 they flash on so quickly I'm not sure I'm really gaining anything).

What am I missing?

Security :: Deleted Certificates But They Keep Reappearing - Openvpn?

Jan 10, 2010

Why is that certificates need to be revoked with openvpn?I simply removed them from the keys folder but everytime the client connects it just places the certificates back into the keys folder itself?! Should that be possible?

Secondly, I have a problems etting the revoke command.Is there a known setting on the openssl.cnf file that might cause this?

[root@server]# source ./vars
NOTE: If you run ./clean-all, I will be doing a rm -rf on /etc/openvpn/easy-rsa/2.0/keys
[root@server]# ./revoke-full client2
Using configuration from /etc/openvpn/easy-rsa/2.0/openssl.cnf

Security :: Public Facing OpenVPN - Open Any Ports On The Router / Firewall

Feb 14, 2011

Within the documentation of example OpenVPN setups there is a setup that shows an OpenVPN Server with two network interfaces. One interfaces is plugged into the public internet network and the second interface is plugged into the private network.

Normally I assume that it would be best to place the OpenVPN system inside the network behind the router and firewall and open only the ports needed on the router to allow access to the OpenVPN system. All other router ports would be closed. This is the first example they show. To see what I am talking about see page(s) 6-7 here -> [URL]

If one were to use the two interface public facing setup, when would that setup best be justified? I guess if you didn't want to open any ports on the router/firewall then this could be justified but then you have to lock down this public system individually instead of having it protected by the network firewall.

Server :: Run An Openvpn Server On A Openvz VPS - Packets Doesn't Reach The Client

Oct 23, 2010

I'm trying hard to run an openvpn server on a openvz VPS, the problem is packets sent from openvpn server process, doesnt reach the client, so connection is never stablished (I run tcpdump on server and wireshark on client to carefully investigate whats wrong), the first guess is that a kind of firewall is blocking traffic (I tried connecting to server through different ISP's but it's possible the national network provider applied some filtering but it cant be on IP,src port or dst port as I'd tried different configuration.

what about deep packet inspection technics, is it possible to block my traffic?) but at exactly the same time I can transmit UDP packets using netcat from server to the guest. there is no firewall enabled in between, I had tried, tcp and udp, tried both open vpn and openvpnAS and tried any thing one can imagine! the VPN is configured as a routed (TUN) type on debian

Server :: OpenVPN Access Server Error: 501 Not Implemented

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.

Server :: Ubuntu 10.10 - OpenVPN And Masquerading

Dec 12, 2010

I have set up OpenVPN Server on a VM (Ubuntu 10.10) running virtualbox bridged to the host. Everything is working fine excepts the fact that I cant seem to be able to assign internal IP (VPN Server) to client connecting. Let me explain: All my clients are connecting and accessing the internet without any issue. Where I have an issue is that all my clients come out the other way on the internet with my server ip address which kind of defeat the purpose. Is there a way (keeping in mind that I am running the server in a VM) to have all my clients accessing the internet with an IP provided by the VPN Server?

Ubuntu :: OpenVPN Server Won't Start After Reboot

Jul 15, 2010

I had recently setup an OpenVPN server on x64 10.04 via the guide found at: [url]

Everything was working perfectly, all clients were able to connect etc.

Today I needed to reboot for a completely unrelated issue - only to find that upon logging in, openVPN was no longer running.

When I tried to execute 'sudo /etc/init.d/openvpn start' I'm presented with an interesting message...

This *used* to say Server. I've double checked all the configs and scripts used in the config and they all check out OK. I purged and reinstalled openVPN to no avail...

Server :: Activate Aliases From A Script?

Jan 17, 2010

I wrote a small script :

#cat myscript.sh
NEWFILE=dojas.sh
touch $NEWFILE

in that script I create some alias commands an pipe them to a new shell script (called dojas.sh) however after execution of that script , I do not see the aliases jan1 and jan2 in my terminal. Even if I execute the dojas.sh srcipt manually , I do not see the aliases in the alias output of my terminal. The only way I can make the aliases active is do the following : cat dojas.sh copy and paste the alias rules, and they are active in my session. How can I make sure that I can activate aliases and they are active in my terminal from a script ?

Note : I am not interested in .bashrc file, I want them to be active in my current session.
