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.
View 4 RepliesI'm running OpenVPN service on both debian server and client. When start connection between client and server, I expect all the computer traffic (except ARP and DHCP requests) go through created tunnel. However, when I capture packets on wlan0 on client (the only connection going outside host) using Wireshark, I can see DNS requests visible and sometimes incoming TCP traffic as well, but most of the traffic is going through tunnel as expected. I provide both configurations of client and server and client routing table for inspection. I changed server address to avoid server exploitation in the case of some big configuration mistake.
Commands to run OpenVPN services are:
Code: Select allFor client: sudo openvpn --config /etc/openvpn/client.conf &
For server: sudo openvpn --config /etc/openvpn/server.conf &
**Client routing table when VPN is OFF**

I searched through many forums and documentation and I found, that for all the traffic going via VPN is command: *push "redirect-gateway def1"* neccessary, however, I have leaks despite this command being in place.

I have (seemingly regretfully) finally upgraded my Fedora Core 7 linux machine that has served me so well for the past decade. One of the final pieces to put in place was my Openvpn config (which was running flawlessly on my FC7) which I cannot get to work.
Here are my steps.
1. Disabled SELinux
2. Added the following entry in my iptables: (although I've stopped iptables to help troubleshoot)
-A INPUT -i tap0 -j ACCEPT
-A INPUT -i br0 -j ACCEPT
-A FORWARD -i br0 -j ACCEPT
3. Yum installed openvpn and bridge-utils (btw I'm using bridging)
4. Configured my bridge-start script as such:
#!/bin/bash
# Set up Ethernet bridge on Linux
# Requires: bridge-utils
# Define Bridge Interface
br="br0" .....
5. Configured my openvpn server conf as such:
proto tcp-server
port 5990
dev tap0 .....
When I execute my bridge-start script it creates the br0 and tap0 then all connectivity vanishes (I can only ping my gateway 10.0.0.50) - internet and any other addresses time out.

my tablet can receive ip, can see ftp on server but can't see anything in my home network.
I use openvpn to connect otherwise isolated machines, and use samba to share filesystems across the vpn, which works just fine.But I recently discovered that copying files using rsync -e ssh is so much faster than copying from a mounted filesystem - like about 5 times faster.I've got comp-lzo enabled in both server and the client, at least I think I have, the directive is there in both the server.conf and the client.conf files, but how do I check that it's active?Does anyone know if I can make openvpn behave more like rsync, because copying is easier than rsyncing?

Is there anything I can do to the push rule of the servers's config file?
I managed to set up an openvpn server, ip-forwarding and a nat iptable rule for that.
Almost everything works as expected, but my problem is:
Smartphone -> VPN -> Internet ==> works (by ip and hostname)
Smartphone -> VPN -> machine in my local network by IP ==> works
Smartphone -> VPN -> machine in my local network by its hostname => DOES NOT WORK
Machine w/ VPN server -> ping to machine in local network by ip or hostname => works
So, i wonder why i cant access a local machine through the vpn by its hostname. I guess I'm missing a forwarding rule??

I have a problem with the Fedora 12 Network Manager - OpenVPN configuration. If I use the same configuration and manually start openvpn (as client) I get connected to the OpenVPN server and I can ping the network that I am accessing. With Network Manager - I get connected but when I try to ping is giving me "Destination host unreachable". The routing table looks similar except that when connecting with network manager is giving me on more route in table

I currently run openVPN on my Debian box that provides secure ipv4 routing from my laptop to my VPS in a different country (and from there the internet via this box). This works fine. However, id like to sort out ipv6 through this VPN as well as IPV4 and not overly sure how to do it. The remote server itself has native ipv6 configured on device eth0 and it works (ping6, traceroutes all fine,incoming to web servers etc) nicely on dual stack.
How would i go about modifying the config (both client and server if needed) to enable openVPN to act as a tunnel broker to enable the laptop to use the ipv6 through the server as well as the old v4? (the internet connection laptop end will not/does not have native ipv6 from the ISP. Currently im using he-net tunnel broker but id like to run myself through my existing openVPN). VPN config details: Its using UDP, port 1194, creates a TUN interface, redirect-gateway etc and the rest is normal config. Edit:- if it matters the clients are all running windows so i cant use sh scripts to set up stuff client end.
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:

i have installed openvpn and config it for a tunnel. my server.conf and client,conf is as follow:
server.conf
port 1194
proto udp
[code]...
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 have been trying to set up openVPN on a Virtual Machine running Ubuntu 10.04 with the eventual intention of having a closed VPN in the workspace I'm at, and a bridged internet connection out through the server.My initial process/instinct was to go through Webmin. After a fair bit of tooling around making eys/certificates, I was able to get a response (and that's all it was, really) from my windows machine accessing the VPN server. However, in my attempt to bridge the network, I have lost all internet/networking capabilities from the server.Fortunately I am able to access the server directly from the hardware underneath (i.e. I don't need to SSH in or anything), and so I've been attempting to restore the server's networking back to default. I have returned the /etc/network/interfaces file to it's original state (just the loop, and an eth0 on dhcp) and restarted the networking. A check with ifconfig returns what seems to be a working eth0, and the loop (noting else) however I am unable to ping any outside server. When I do, I am given the message:From XXX.XXX.XXX.XXX icmp_seq=1 Destination Host Unreachable(where of course XXX is my IP address).nother VM on the server is able to access the internet just fine, so it's not the overall server hardware...I guess at this point I'm just trying to take steps back,

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.

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

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:

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:

remote openvpn.xxx.com 1194

nobind
persist-key
persist-tun

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 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 want to see what is the configuration of my Wind River Linux (actually I want to see what modules are installed in it when it was built). I can't find the configuration file.
