I had configured Openvpn(2.0.9) server On Centos Machine>its working fine.i had already created keys for clients.Now i want to create one more key for new client.When i tried the "./build-key user " command its showing ""Please edit the vars script to reflect your configuration,then source it with "source ./vars".Next, to start with a fresh PKI configuration and to delete any previous certificates and keys, run "./clean-all".Finally, you can run this tool (pkitool) to build certificates/keys."".
Is there Any way to add more keys without changing Existing keys.
i have some problems with configuring openvpn tunnel connection to my openvpn server. I'm using static-key tcp connection. Network manager always said to me that connection could not be established. Also, when i try to run openvpn from terminal, i got some strange permissions problem:
Code:
openvpn --config config.ovpn Mon Apr 5 15:48:37 2010 OpenVPN 2.1_rc19 i486-pc-linux-gnu [SSL] [LZO2] [EPOLL] [PKCS11] built on Oct 13 2009 Mon Apr 5 15:48:37 2010 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables Mon Apr 5 15:48:37 2010 /usr/sbin/openvpn-vulnkey -q moj.key
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.
I connect to a VPN using openVPN. Now, after the connection is established, all my traffic goes through tun0. My LAN gateway is 10.100.98.4... So, for apps to use my direct internet connnection I did
sudo route add default gw 10.100.98.4
But, I cant use tun0 now. I know this because
curl --interface tun0 google.com
doesnt give me anything.. How do I go about using both connections simultaneously. How can I achieve that?

I am trying to start a 2nd openvpn service on my server so that clients can connect via udp instead of tcp.However when I run: openvpn /etc/openvpn/openvpn2.conf
I get no response at all.Usually I would expect the startup parameters or at least an error but I get nothing. I have to CTrl+c to get back to the prompt.ANy ideas what I can try?I changed the serve config so it has tun1 instead of tun and also changed the log files to openvpn-status2.log so it doesn't overwrite the other server.I also changed the network so there wouldn't be any IP conflicts. Openvpn1 runs on 172.16.x.x
i want to setup openvpn with preshared key. i want to make my linux system as openvpn server and windows machine as client. both the systems are same LAN. i am using centos 5.3 and windows xp. can u tell me the steps to create a vpn between these two using psk.
I have installed an OpenVPN server on my OpenWrt 10.03 router [freshly flashed]:
[URL]
It seems "ok".
I connect my pc to the lan port of the router, and i want to try it out. I'm using Fedora 14 with GNOME. In the NetworkManager applet i set these things: this and this. Ok!. i try to connect, but it fails. Here are the logs: [URL]
one important thing: my routers [the one with the openvpn server] ip address is 192.168.1.2, and i didn't had to write it nowhere. so how could the networkmanager applet know the ip address of my openvpn server? i think this is the problem, but i just can't find where to write 192.168.1.2
p.s.: yes, i tried to google for: "No server certificate verification method has been enabled." but i didn't find a thing, and i'm trying for hours now... :
p.s.: if i [on the router]: iptables -P INPUT ACCEPT iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT
I need to know the procedure to setup VPN between two network. i setup openvpn access server to do this easy. 1. Step by step procedure to setup VPN 2. Setup VPN with DHCP 3. How to check that open vpn is running successfully.
I'm using openvpn under linux OS which is Fedora Core 14, in the folder "/etc/openvpn" i put 5 files which belongs to the network server that I should connect to, files are : two files with the extension ".crt" two files with the extension ".key" one file with the extension ".conf"
Now, when I issue the following command (as root) : Code: /etc/init.d/openvpn start It asks for my username & password to the network server, & after I entered the required authentication information, I successfully login, but I get disconnected automatically after two or three seconds.
- I connect to the network without any disconnection or problems under windows - I use openvpn version "openvpn-2.1.1-2.fc13.i686" - there was a bug in my OS "Fedora core 14" which is that I cannot activate or deactivate any ethernet cards, which solved by disabling NetworkManager in all run levels - I disabled iptables - I disabled selinux - I got this error in /var/log/messages file when I disconnect from the openvpn network "

- I couldn't find the file called "/etc/openvpn/update-resolv-conf"
i have Fedora 14 OS, i installed an openvpn, & i got a problem with it, which i get disconnected automatically after successfully logined, one of the members here (ZeroSignal ) told me to comment any lines in /etc/openvpn/anyname.conf file, which contain the word update-resolf.conf, & my problem get solved, but now after i logined to the openvpn network & after half an hour (or less sometimes) i got disconnected from the network.
I had configured openvpn (2.0.9) on my Centos 5.4 machine.I want to route all client traffic through my gateway.So i had enabled (push "redirect-gateway ") in server configuration.Now the problem is the upload speed is very low while connecting through vpn.Normally i got 700 kbps download and 650 kbps upload speed.But while connecting through Vpn the upload speed is only 110-130 kbps but download is almost stable.Here is my Server and client conf Files.
I've set up OpenVPN on a Linux server. All my Internet traffic goes through the VPN from that server. I'm running Windows 7 at home. I noticed in Wireshark that DNS queries are not going through the encrypted tunnel, but instead directly to my ISP's designated DNS servers.
To overcome this, I tried pushing DNS for OpenVPN from the server to my computer, and also inputting the DNS address in my wireless adapter's configuration options. This appears to have secured the DNS leak, but is it the proper way to go about it? If I didn't push the DNS address from the server to the client and only set the DNS in the client's wireless adapter, then I couldn't visit any website. And if I just pushed the DNS but didn't set it in the adapter, then some DNS requests still leaked to the ISP's DNS servers.
I'm trying to setup openVPN on debian, well this worked. But every client will get the same ip (172.17.0.6 - local it is). how to set my server in bridge mode. I've read about: server-bridge LOCALIP 255.255.0.0 172.17.1.20 172.17.1.100
BUT, my server has no ipv4 address, but only ipv6: 2001:41d0:2:b2d6::542a:74a so I am not sure how I can do this.
I've been working with my OpenVPN server for a while, and I have a rather interesting problem. I need to redirect all client traffic through the tunnel except for a couple IP's that need to be resolvable locally. The way I'm doing this is pushing these routes from the server:
Server 'PUSH' directives
push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4"
I'm seeing that translating into these Windows routes:
Windows routes occurring

I've hidden my server's IP beginning with 199 for security purposes.What I've gathered.I'm assuming that 0.0.0.0 is a kind of code for "everything," so I'm not sure how I could get this to work, but the general idea is that I need a specific IP range (172.16.*) to be resolvable on the LOCAL NETWORK (of the client) meaning it does not go through the VPN tunnel and the client can connect to 172.16.* locally.Is this possible? Routes can be executed through the command line, server "push" or client config options. Any way to get this to work while still routing other traffic through would do, really.
Additional Info: I have the server running on Debian 64-bit and the client running on Windows 7 (although Vista needs to work as well).Client/server configs can be provided if needed.
I only have very basic understanding on how it works.This question may have been asked so many times, and honestly I've tried so many tutorials and have read a lot of articles but it all didn't worked. I may be too stupid to have this done, or it is just the lack of knowledge.
Here it goes,I have a VPS with a host which runs OpenVZ in LA. I want to create a VPN tunnel to the VPS and tunnel all my internet traffic to the VPS. Can somebody please help me out on the step-by-step?
I was once able to configure the VPS to run OpenVPN and my client pc was able to connect to it, but the internet connection is still thru with my local connection. Did it with a tutorial too. I would also like to ask, The VPS has 512mb of RAM, I was wondering how many clients can it handle at the same time.
I'm using Debian Lenny and I want to tunnel rtorrent only through a OpenVPN tunnel. I have a tunnel running, the config file looks like this:
client dev tun proto udp remote openvpn.xxx.com 1194 resolv-retry infinite nobind persist-key persist-tun
[Code]...
My idea is that I could run a sockd proxy internally that redirects traffic to the openvpn tunnel. I could use the *nix "proxifier" application "tsocks" to make it possible for rtorrent to connect through that proxy (as rtorrent doesn't support proxies). I have trouble configuring sockd as my IP inside the VPN changes every time I connect. This is a config file someone said would help:[URl].. As my IP changes at each connect I don't know what to put in that config file. I have no control over the host side config file.
I an unable to connect to an openvpn connection in ubuntu karmic. I have installed openvpn , I added the user certificate, CA certificate , Private key and the conf file in the /etc/openvpn directory. Also followed the steps given here [URL]..community/OpenSSL under "Importing a Certificate into the System-Wide Certificate Authority Database" , but still when I try openvpn --config linux_client.conf I get the following error.

I have set up an openvpn server on ubuntu via port tcp 443. The server use a public network and almost every ports are blocked (not 443) So when a client connect to the server, if it send traffic needing a blocked port, the connection cannot been etablished of course. So i d like to know if it is possible to redirect all incoming traffic on the server to an other unblocked port (like 443) to bypass firewall.
I dont think openvpn offer this possibility but maybe with linux it is possible..
I have Debian / Ubuntu / Xubuntu. I'm trying to distribute and run a Python file with the least number of clicks for the end user. How do I create a PKG file for Mac OS X on Linux?
I can currently boot into a given Linux distro on my hard drive. Is there a generic way, for any given Linux distro, in which a boot CD can be created to boot that particular distribution to a login prompt ? The boot CD would need to bypass booting from the hard disk.
Before you say, use the installation CD ( or DVD ), I have repeatedly run into problems booting into a Linux distribution from the installation CD, for quite a number of distributions. These distributions have a so-called repair mode which quite often does not work, or has been gratuitously removed in some current release.
Before you can say, use SuperGrub ( or SuperGrub2 ), both have failed abysmally on my computer in a number of situations.
I am looking for a generalized cookbook solution for any given ( fairly modern/recent ) Linux distribution for creating such a boot CD for that distribution.
Searches on the Internet yield to me a bewildering series of conflicting info so I am asking here believing that there must be some surefire solution generic to Linux itself.
I want to burn a dvd with some data directly without creating .iso file before burning.right now i use to create an iso file first using mkisofs or dd command and then burn using cdrecord command.But i want to know whether is it possible to directly burn dvd without creating iso first?i use following commands-
I need to change the functions of some linux commands. We can't edit the binary files provided in /bin, is there any other method other than alias.For ex. - I need to change the function chmod so that it takes only three consecutive integers as input (chmod 777 filename) and nothing else ? Do I have to write by own code for it, or is there any other alternate method.
I have a hdd with WindowsXP that I'd like to install on Virtual boxe. The hdd is currently in use, but can put in enclosure to perform operation. To do the planned operation, what is the best way? Do I need make iso image of hdd? Or can I install directly to vboxe?
Let us assume I have a zip file called patch.zip, when I run unzip -l patch.zip I get the following output.

To this zip file I want to add a new file, "Readme.txt" located at /path/to/Readme.txt in such a way that, when I re-run unzip -l patch.zip again I get something like this
I'm trying to create an extended partition. In GParted, I shrunk the size of the existing partition and now want to create a new EXTENDED partition in the free, unallocated space. GParted only lets me create a PRIMARY partition. What am I doing wrong here?
Here's what I've got right now:
You can actually ignore the flag for the swap as "boot." That was me just messing around trying to get it to work. I've removed that flag. Not sure how the question of boot affects all of this...maybe it factors in somehow.
There are basically two main limitations with hard links:
Hard links normally require that the link and the file reside in the same file system. Only the superuser can create a hard link to a directory.
Thus, symbolic links were introduced to get around the limitations of hard links. So, the question is, are hard links still needed? Might there be situation where they are more useful?
