I've been the las 4 days setting up my first VPN (OpenVPN bridged). The server is up and running OK but when I try to connect I've got this message in the client log.

I have openvpn tunnel setup between two CentOS servers. One of the CentOS servers also acts as a DHCP server for some client computers.
Server A= OpenVPN server
Server B= OpenVPN client (connects to Server A with OpenVPN)
The two CentOS servers can ping each other (172.16.0.0/24) via the tun0.
However, client computer connected to Server B (DHCP server) can't reach 172.16.0.1 (which is the OpenVPN server).
I think I am missing some routing in my "ip route show". Following is the full picture:
What command can I issue to get this fixed? something along ip route add?
There is no firewall service on both end. service iptables stop! I can't bridge eth1 and tun0 as DHCP server might mess up the other side. I can't do a push of "redirect-gateway def1" because then clients loose their IP as they send DHCP requests to Server A.
Followed this guide to the letter:[URL]..
Tried to run command:
sudo /etc/init.d/openvpn restart
And just get a fail returned.
This is what the log-file says.

It says init bridge br0 does not exist. Do I need to create it in the network config or something?
i recently rent a VPS and installed with CENTOS 5 64bit, i followed a tutorial to install openVPN to bridge traffic to my windows machine.

I assume the failed read line is the culprit. I am currently running on a test machine. There is no firewall. I read on this error points to a firewall misconfiguration, but there isn't one.

I tried this config file at Windows OpenVPN client and all works fine.
what is the best way here? I have like 5 servers, and I want my clients to access each of them, so in case 1 server is down, they can access remaining servers. Also, it will work like user1 chooses the server number and is connecting to a central database, then reply is OK, and he can connect to the server number he wished.

I re-installed openvpn but it doesn't work neither. Then I searched for this issue, find that it is possibly caused by disabled DHCP Client service. I checked, and found it was enabled. Still won't work after restarting dhcp client service.

At some point my Ubuntu 9.10 Desktop install has stopped being able to connect via ftp to servers. I have several servers that I have accounts to and I have several ftp clients installed on my system, including gftp, Filezilla, and command line ftp tools. None of them can connect to any of my servers.
Here it is from the command line:

I can connect fine with my netbook running Ubuntu, only my desktop has this problem, and of course I use my desktop for development. Do I have a firewall running or something that's blocking my outgoing requests over port 21?
I try to establish basic connection between my 2 end systems using openvpn. The problem is when i move the client files to my laptop i cant even ping the server from there. I copy paste the server commands in section 4 [URL] ....
In the client i ran the first command and changing VPNSERVER IP with 10.9.8.1 and LOCALGATEWAY IP with 192.168.1.1
which i thought that whats the server use : ROUTE_GATEWAY 192.168.1.1/255.255.255.0 in the server initialization process
The second command produce error device tun0 not found and when i create one using openvpn --mktun --dev tun
I get RTNETLINK answers : network is unreachable
Note : I use wireless connection in the client system (laptop). The server works good and i could ping him ( from the same machine ) but cant ping him or access the vpn server in my laptop. I also use default openvpn settings...
I have a private server which I stream media from, but since I've installed VMware running Windows 7 and set up Windows to used a bridged connection, so I can access the network drives in Windows. Now that I have done that, I cannot connect to my home server unless I have VMware running.
I only want windows running when I need it, but I need access to my server at all times.
We use Openvpn for remote access to the office network. It would be nice to keep this running and automatically connect to the office at all times.Once started, it does this anyway. The problem lies when the user comes into the office. Openvpn connects as usual to the vpn gateway, but this causes weird routing loops.Is there a way to say to Openvpn "Always connect to the gateway unless you are on network 10.10.10.0/24" ?

I have a network that consists of a few desktop machines, laptops, and two Internet connected linux servers. The Linux servers are the gateways, routers, and firewalls for my desktop and laptop machines.Whenever I'm away from home; I can connect to my home machines over the Internet by first ssh'ng (technically I use Webmin; because my firewall on each Linux servers blocks ssh from the Internet.) to one of the linux servers and then ssh'ng to the desired machine on my home network.
This works fine for my home linux machines. But not my Windows machines.I'd like to be able to rdp or rdesktop to my Windows machines.Will OpenVPN allow me to accomplish this ?

i have added a vpn connection on my Lucid desktop machine, but every time i try and connect, it fails. I also have the same, identical vpn connection on my karmic install on my laptop. everything works perfectly on Karmic, but Lucid is having problems. I have followed identical steps for creating the vpn connection on both machines: vpn connections can be made in 2 ways, the first is through the network manager, but trying to connect through the nm-applet returns an error about vpn failing to connect and "no valid vpn secrets".
I suspect this is at the root of the problem. The only way for my Lucid machine to successfully connect through the command line is if I run the openvpn command under sudo.
I have setup an OpenVPN server on Ubuntu server. I am able to connect with Windows clients. I am, however, unable to correctly connect using Ubuntu.
If the router firewall is blocking the pings to keep the connection alive, then the connection initially does not work, but will work after the first timeout and reconnect. If the firewall does not block the pings then the initial connection attempt never times and therefore the connection does not work.
Attached is the readout from the client.
The first attempt gives error ERROR: Linux route add command failed: external program exited with error status: 7
Successive attempts work, they just time out every two minutes.
This is as far as FireFTP can go to make a connection.

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?

Suppose I have a server, foo, that runs on port 5555. I can make one connection to it at a time on that port. I want xinetd to fork new instances of foo so multiple clients can connect to it.
Here's a configuration entry:
1) How does xinetd fork a new instance of foo when a previous instance is already listening on port 5555? Wouldn't the new process fail to launch because port 5555 is already in use by the previous process?
2) Suppose five clients connect simultaneously, and xinetd forks five instances of foo. When the clients disconnect, does xinetd leave all five instances running?

I'm trying to setup OpenVPN in order to connect back to my home network while traveling for secure browsing and such. However, before I can even start trying to set that up I tried to see if I could open port check my computer through the net. And I'm having a hard time doing that.
As far as I can tell, here are my roadblocks:
1. Is ISP (Qwest) blocking my ports?
2. Is my modem doing the proper port forwarding and firewall?
3. Is my router doing the same?
4. Is my firewall on the computer allowing the request?
To minimize sources of error, I've turned off my local and router firewall and setup my router to forward ports. I'm not to familiar with my modem, but I'm pretty sure that the firewall is turned off by default and I think I've done port-forwarding correctly. But still no success when doing an open port check. At this point I don't know how to diagnose the problem.
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.
