Server :: OpenVPN Client GUI For Windows 7 64Bit?

Feb 9, 2011

I have set up my Openvpn Server in Centos and it is working fine. Windows XP clients are able to connect the OpenVPN Server and access the network. This is a customized OpenVPN Gui Client. Now I need the customized OpenVPN Client for MS Windows 7Bit. I am using openvpn-2.1.4-install OpenVPN Client in MS Windows 7 64Bit. This is a executable and working fine in the said architecture. Now I want to compile this version. I am following the given steps at : [URL].. As per the direction i have copied the source from 2.1.4 and tried to compile, but compiled copy is giving the error " An error occurred Installing the TAP-Win32 Device Driver". I have tried this compilation by making every change and hack but all in vain.

I think that there are some certain steps which are missing and not documented any where. And sure that someone in forum will know the facts.

CentOS 5 Server :: Openvpn Connect To Samba Share From Windows XP Client?

Sep 15, 2009

I'm trying to set up a VPN connection between our CentOS 5.3 server at work and my bosses XP computer at home. At this point, we are kinda locked into Quickbooks. I'm testing the connection from my XP boot at home to see if it works. I can log into our servicemanuals easily enough from XP at home however, the windows takes forever to update. I have the Samba server only listening on port 445 because is seems to work more efficiently at work. I connect to the Samba shares via linux from home and everything works well but, when I try to do anything with the shares from Windows client at home, it's very slow!

I'm thinking that it must have something either to do with the Windows OpenVPN client or the client.conf file. Is there anything I should look at in the .conf file for answers?

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

Ubuntu Networking :: OpenVPN Server And Client At Same Time?

Oct 26, 2010

I have an Ubuntu server that is currently running Ubuntu 8.10. I was thinking of making it a VPN server for my iPhone and also for my laptop whenever I'm outside and need to access internet over insecure wireless networks. Now that part should be easy I found several guides on how to configure OpenVPN server, as well as enabling clients on iPhone, and OSX.

However, the things is that my server is currently a OpenVPN client also, I have a paid tunnel set up to bypass my ISP blocking incoming traffic on various ports. Is it possible to keep this setting but still enabling a VPN server? Essentially causing traffic from my external device to go in through my tunnel to the VPN server, and then out through the external VPN provider.

Ubuntu Networking :: Config OpenVPN Client For SwitchVPN In Network Manager From Windows Ovpn Files?

Jul 17, 2011

I have ovpn configuration files for Windows from SwitchVPN. They do not provide configuration files for GNU/Linux. They said I can extract the certificate and key files from the ovpn files, but I'm confused about how to do that.First of all, I don't know which Authentication Type to choose: "Certificates (TLS)," "Password," "Password with Certificates (TLS)" or "Static Key."

Second, I don't know what to put where from the ovpn file. I see a <ca> � </ca> section and a <tls-auth> </tls-auth> section, but I don't see how those correspond to any of the Authentication Types. "Certificates (TLS)" and "Password with Certificates (TLS)" require two certificates and a key, "Password," requires one certificate and no key, and "Static Key" requires a key and key direction but no certificate. When I connect to SwitchVPN in Windows, it asks for a user name and password.Here's an example of the ovpn files (certificate and key contents removed):

Quote:

route-delay 3
fast-io
client
dev tun

[code]...

how to get what I need from the ovpn files, and which Authorization Type to choose in the Network Manager VPN configuration GUI, and what to put in the blanks?

CentOS 5 Networking :: OpenVPN Doesn't Work On CentOS 5.3 With Windows Client?

Jun 27, 2009

This will be a little long (having read Phil's 'how to ask questions' FAQ). I'm trying to get OpenVPN working between my CentOS server and some Windoze laptops running XP. There seems to be plenty of sample
config files available, but to date, none of them have worked for me. Pulling out my trusty Wireshark, I've found some clues,

BACKGROUND:
My local subnet (NAT'ed by my gateway router) is 192.168.52.x. My router has been configured with a conduit (port-forward) for port 1194 (the standard OpenVPN port), which points towards my CentOS server.The CentOS server is .52.112, and the supplicant is .52.110. I have tried the lient both inside and outside my local subnet, with no difference in events or outcomes.

(please make it an idiot proof anwser because i have limited knowledge about iptables). I was thinking like forwarding (the router in the network with the openvpn client is also firewalling with iptables) the request of the ip class of the openvpn network to the computer with the client,which masquarades the interface

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.

Fedora Networking :: OpenVPN Client Disconnects Me From LAN / Fix It?

Sep 15, 2009

This is the first one of probably many posts as I am new to Fedora having lots of questions. This one is about the openvpn client which is used by me to connect to my company network. Thanks to the Fedora FAQ it was easy for me to set up the client and establish a connection. There is just one problem every time I open a connection I am disconnected from my local Internet. I was using openvpn on my Windows XP PC before and there was no problem keeping two Network connections, the (W)LAN and the vpn tunnel. Does anyone know how to solve this? I am utilizing the latest Fedora 11 release and configured openvpn client via the Network Manager GUI.

Ubuntu Networking :: OpenVPN Client Not Setting Up?

Oct 1, 2010

I am trying to connect to an existing VPN server that I have been using for years now. I am moving my develpment environment over to a Ubuntu box and I must have openvpn working in order to access SVN. It has been a few years since I have been setting up linux boxes. And networking is a soft spot for me. But

The server has been running without problem for a LONG time. A windows computer I have been using connects to it fine and I can access the network on this machine. I am setting up a new computer, but when trying to connect openvpn starts the initialization sequence completes but I cannot ping the network I am trying to connect to.

I use a second VPN connection to connect to an alternative network and it works fine. The difference between these two is that the working vpn connection is a routed IP tunnel and the one that is not working is a bridged connection.

The VPN that is working on this box brings up tun0 while the bridged connection connects but does not bring up a network tun device. The server logs look normal, it just looks like the client is not setting itself up to use the network once connected. (The key/cert pair work find when on a windows box) Just not on this new ubuntu build.

My current client config

Quote:

cert eric@home.crt
key eric@home.key
client
dev tap

[Code]....

The server is using tap, as well as the working windows client uses "dev tap"

It has been a long time since I have been maintaining linux boxes but its coming back slowly.

Do I have to bring a device up manually ?

Server :: Calling Remote Apps On Windows Server From 'buntu' Client

Apr 23, 2010

My desktop is running 'buntu 9.10 and I have recently aquired a couple of half decent servers running Windows server 2003. I have a few windows app's that I use regularly for work that I have had limited success in running with wine or in vm's. I stumbled upon a how to to call apps in a vm to run seamlessly on the host desktop and did some playing and have succeeded in calling app's on my servers from my 'buntu desktop, the command I have set in my launcher for one of them (DIALux)

My question is, can I change the default application/file association in 'buntu with a custom command so I can double click on a file and have it open in one of these remote app's??If I can, what is the correct custom command to be using as using the above doesn't work at all, it just tries to open the file with rdesktop not the remote app.

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 192.168.3.0/24 and access Internet through a firewall via a front-end zone 192.168.65.0/24 with wlan0 interface.

But my laptop can access on a back-end zone 192.168.2.0.24 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 192.168.3.2 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 Networking :: 9.10 - OpenVPN Client Fails (Error Status 7)

Jan 9, 2010

I have openvpn server configured with bridged interface on my openwrt router. The client is running ubuntu 9.10 with config:

Client
dev tap
proto udp
remote x.x.x.x 1194
resolv-retry infinite
nobind
persist-key
persist-tun
ca /home/blwegrzyn/openvpn/ca.crt
cert /home/blwegrzyn/openvpn/client1.crt
key /home/blwegrzyn/openvpn/client1.key
comp-lzo
verb 5
(x.x.x.x was hidden)

When the client connects the log says:
WRRRWRSat Jan 9 20:16:03 2010 us=332404 PUSH: Received control message: 'PUSH_REPLY,redirect-gateway,dhcp-option DNS 192.168.1.241,route-gateway 192.168.1.254,ping 10,ping-restart 120' .....
Sat Jan 9 20:16:03 2010 us=343906 ERROR: Linux route add command failed: external program exited with error status: 7

The server is trying to push default gateway 192.168.1.254 to the client and the client is on 192.168.2.0 network as you can see the route addition fails with SIOCADDRT: No such process. This is because the tap interface does not have any ip and the route addition is not possible. The tap interface is not getting the dhcp address through the tunnel, not sure why (this works on XP). To fix the problem I must manually add the ip to the tap interface, and the default gateway, but then i must add dhcp server to resolv.conf to make it work and once I disconnect the computer does not know the old valid dhcp anymore and cannot communicate. Why openvpn cannot get the ip automatically? Why it cannot grab the dhcp from the tunnel? Is it related to the wireless card being managed by the network manager? This works perfect on windows machine (xp sp3).

Ubuntu Networking :: OpenVPN Client No Buffer Space Available (code=105)?

Jan 26, 2010

I'm using OpenVPN 2.1 on Ubuntu 8.10 to connect to LAN behind an IPCOP server. Everything works fine except when I move across the tunnel files which are over 180kb, then I get UDPv4 []: No buffer space available (code=105 surfing the Internet I've found post that suggest to increase these settings on the kernel

> sysctl -w net.core.rmem-max=8388608
> sysctl -w net.core.wmem-max=8388608
> sysctl -w net.core.rmem-default=65536
> sysctl -w net.core.wmem-default=65536

those have actually made a small difference, but not enough for uploading even an image over http. I guess that I can keep increasing those values till I'm not satisfied, but as I'm not sure on what I am dealing with, can anyone tell me if there's a rule of thumb? My machine is a laptop with a dual core processor and 2GB ram.

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

Networking :: Samba Client Shares Disconnect Over OpenVPN Connection

Jun 23, 2010

My network is barely functional. I'm running 2 linux servers connected by openvpn (tun) through routers on both sides. There are Windows clients (98 and XP) on both subnets. One server (ls3) acting as PDC for the domain. The Windows clients use the respective linux boxes as gateways. On the server side (ls3 which is both openvpn server and samba server), all the clients can read/write properly to shares on both sides. The problems are all on the client side. Share connections to the server side disconnect after a few moments.

Browsing on the client side windows machines is fine. I can see shares on the server side. Some server side files open and are readable, writable, other server side files will not open. Some samba logon scripts on the server side can be opened from the client side. Others open after a long wait to a blank file! Permissions on server side files are set to 777 for testing. If a file won't open or reads "blank", that doesn't change no matter how many times you try. A non-readable/writable file overwritten by a readable/writable one can be read and written to!

I can ping successfully from any client on either side to any other client by either ip address or workstation name. Firewalls on both side are set to forward tcp and udp traffic going to port 1194 to the respective gateway linux boxes. Iptables on both linux gateways are down for testing. I tried reversing the openvpn server/client roles with the same result; the same physical side of the network had the problem. On one of the windows 98 clients, I wiped out the networking configuration completely and rebuilt it from scratch. Same result.

One one of the windows xp clients, I tried to rejoin the domain. It went through successfully but the result was the same as above. The network was operating smoothly for several years until the client side dsl modem broke last week. It was replaced with a newer model and at the same time I migrated from a pptp connection to openvpn. How to resolve this, Is this something to do with openvpn? Is this a network hardware problem? Am I missing something in the port forwarding on the routers? My smb.conf files are ancient except I added interface tun0. I have never seen 2 files sitting next to each other in the same directory where one opens and the other doesn't!

I'm running Mandrake 9.2 on the client side and Mandriva 2008 on the server side. I have a Sonicwall firewall on the server side, a Westell 7500 on the client side. I note that during the modem install, the http port was opened to the linux box on the client side and the access log got huge over the weekend and I ran out of disk space until I closed it down and deleted the log. I tried a simple test while viewing /var/log/daemons/errors on the client side. From a windows workstation in the client subnet, I opened a dos window and tried to print a file located on the samba server on the openvpn server machine which I knew NOT to be problematic.

The file printed and there were no errors reported in the log. I repeated the test with a known problematic file. The file would not print. The errors log noted:
Authenticate/Decrypt packet error: packet HMAC authentication failed
I regenerated the static.key file on the server side and scp'd it to the client side and restarted both openvpn's. I checked for duplicate files named static.key on both sides. Same error.
