I'm using OpenVPN to connect to a remote system. When I run

It brings up a new tunnel interface. The problem is that once the tun interface is brought up and the VPN is established, my whole Internet connection slows to a crawl.
Here is the output from ip route show before openvpn:

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 an OpenVPN setup at work, and windows clients are able to connect fine. On my dual-boot system (Windows XP 64-bit and Ubuntu 10.10 64-bit) I'm able to connect on Windows but not Ubuntu. I use the same files for each. The network manager wasn't working, so I'm doing it via the command line right now:
Below is the output (sanitized)

Does this mean it's connected? If so, I'm not able to ping anything on the remote network, not even the OpenVPN server.
I am having problems setting up openvpn with networkmanager. I am running fedora15 with the newest networkmanager. Okay here is some info...
openvpn runs at boot time no problem...
Here is a copy of the boot time message from /var/log/messages

Here is a copy of tun0 from the ifconfig, and also you can see that openvpn is running from the command "netstat -ntl"

Here is the options i am using for server.conf for openvpn.
Code:
Okay well when i try to add openvpn to network manager i select the openvpn option and it ask for the required fields.
For gateway i am using -> 10.0.0.0
ALL other options i am just using the defaults...
Now i am not sure if they options that i am using is correct... if anyone has any input i would love to hear some.
Now when i try to start New VPN Connection from network manager it fails to connect and here is what i am getting from /var/log/messages
Code:
If you want to recommend command line options instead of using the network manager gui i am okay with that...
I have an openvpn bridge up and running (ubuntu to ubuntu, both in vmware fusion machines on macs). My problem is that I cannot get a connection faster than ~9mbps even though 20+mbps is available. I've been troubleshooting for a while and have tried many fixes. I just now did ethtool tap0 and I think maybe I found it. It says the link is 10mbps. I tried to change it with:
sudo ethtool -s tap0 speed 100
but it says ethtool cant change speed on tap0. How can i define the link speed of tap0?
I have installed OpenVPN for network-manager using "sudo apt-get install network-manager-openvpn". Now I have it in my network-manager, but I dont know how to configure a connection, I have a configuration script, when I import that script in network-manager it automatically creates a connection, but still problems exists ...
View 3 Replies View RelatedI 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.
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.
I installed all the necessary packages for the networkmanager-openvpn function to function. The openvpn-connection-setting are successfully imported into the networkmanger via the conf file but the apply button is grayed out, so that actually saving and using the connection isn't possible? Does anyone know, where the problem is? It's a fresh install of Ubuntu 10.10 after the upgrade from 10.04 sent the networkmanger down the drain.
View 2 Replies View RelatedAs I reported in this bug:[URL].. root is not able to start an openvpn-connection via the "nmcli"-command to control NetworkManager, whereas my user does not run in any problems with this command. My error output when starting as root is as follows:
Code:
# nmcli con up id "my-openvpn"
Active connection state: unknown
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/5
state: VPN connecting (need authentication) (2)
Error: Connection activation failed: no valid VPN secrets.
Does anybody know what to do about this strange behaviour? The vpn-secret seems to be stored in the gnome-keyring and in the /etc/NetworkManager/system-connections/my-openvpn simultaneously. But root cannot access any of these. Why this is important? I'm trying to set up a dispatcher-script to automatically start openvpn on eth-connection. but this does throw the exact error from above (no valid vpn secrets..).

I have freshly installed OpenSUSE 11.3 64 bit and reimported my old openvpn connections via Network Manager. Connection can be established fine, but after 3 to 6 seconds (pings) it will stop to receive any packets on the tun device.
I tried disabling the firewall, starting openvpn manually, no avail. I checked the message log and the openvpn output, no messages recorded.
I am trying to connect to an OpenVPN connection using the gnome-network manager.
I'd like to point out that using the configuration file in /etc/openvpn works perfectly but I have no way of knowing if the connection has dropped.
When I set up the connection in the nm it connects for a few seconds then fails. The /var/log/messages file shows this:
When I make a vpn connection to an openvpn server, I loose the internet connection.
The VPN works all right.
Server config (extract)
Client config
Client route without the VPN connection
client route with VPN connected (internet lost)
Is there anything I can do to the push rule of the servers's config file?
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.
I have a Actiontec m1000 modem from Qwest that seems to offer more speed to my brothers Windows PC then my Linux PC (same make and module) I checked the ping on all systems, and they all look fine. The only thing that seems different is the number of open sessions in the modem, Linux only uses 2, and Windows uses 80. My guess is that the modem uses sessions to control the bandwidth, but I don't know how to add sessions to Linux networking to compete for bandwidth. I did test in the same browser.
View 4 Replies View RelatedI have succesflly installed OpenVPN server and clients(followed tuts). Everything is great, however when I have openvpn connection established on the clients I loose the basic internet connection in the browser, but my clients can see the vpn server(even I can ssh to the server via the openvpn client ip). I am guessing that all the traffic is routed through the server. I am just not knowledgable enough with routing , iptables and internet sharing. I am using tun based setup on OpenVPN. I am just not even sure if this is a server or a client issue, sorry for ignorance and illeteracy.

I have Ubuntu 10.10 running on a Dell Latitude E6500 notebook and am using the Broadcom STA wireless driver (just in passing, same happens on Mint 10).
My problem is this:
- when the computer is plugged into a power outlet, wireless works fine, but
- when the computer is running on battery, it hardly works at all: The network strength indicator item still shows the same connection strength but data are not transmitted anymore or only extremely slowly (google.com might 2 minutes to load).
The drop in performance literally happens 1 sec after unplugging it, and once the notebook is plugged into external power again, it resumes after a few seconds. (I have tested this with big downloads where you can see Firefox's or the Update Manager's download speeds.) The BIOS doesn't seem to have power saving settings that make that happen, and I haven't found any in Ubuntu.
I am programmatically doing a large FTP upload (about 5 Gb's of 2-3 Mb files) from my Windows 7 machine to a ProFTPd server on my Ubuntu box. When the program is run, transfer rates are huge! but as run time continues, transfer rates drop off significantly and eventually slow to a halt resulting in a:

Read Timed Out
error.
The rest of the uploads fail due to Socket Read Errors.
Why is the transfer failing like this?
I'm having a weird problem that I'm hoping someone can help me with.
First some specs:
F13
NetworkManager Applet 0.8.3.998
Driver r8169
Opera 11 and Firefox 3.6.16
Recently my ISP switched to PPPoEand since then my internet connection has been giving me problems. While browsing, some websites load fine, some websites load fine after I refresh once or twice, some load really slowly and the formatting tends to be messed up and some websites won't load at all (they stop at waiting for website...). Ping for all of these sites is however fine. Also uploading and downloading either from sites like rapidshare or using torrents is also fine. The same ISP also provides a second similar connection which is connected through a wireless router (mine is connected directly - no modem or router) to two computers (one via a wired connection and one through wireless) both running Win 7 and everything works fine over there.
Things I've tried. I tried using the router changing it's setting to my connection and connecting through that but the problem remains. After googling I thought it might be an MTU issue so tried this:

Is there any way to run successfully umtsmon with kvpnc? Trying to build up a connection to a VPN provider using his profile openvpn and kvpnc. It connects as "low level connection" , the indicator of kvpnc remains red, but then kvpnc would not pass the network traffic through umts-mon (or better vice versa, umtsmon doesn't). In principle I would like to pass both interfaces (wireless, umts) through vpn.

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,

Right now I have a few IP's : on eth0 I have IP from my ISP, on eth0:1 I have my own IP.I set up MASQUERADE to eth0 - but in this case when I try to access my restricted resources IP address from ISP is visible.
What I want is to use my own IP address from eth0:1 - could somebody help me to build good working redirect entry for that? I want to redirect all connections to that IP assigned on eth0:1... - just to access Internet using my IP.
i've set up an openvpn server (with dhcp running on it) and i have to create compatible clients.the problem is how to get an ip by dhcp.with ubuntu i made a script like this
/sbin/ifconfig tap0 up
/sbin/dhclient -e tap0
and everything works fine:tap0 goes up and then start a dhcp request to the server on tap0with fedora there is a nice problem i've noticed that is impossible to run dhclient later on a new interface because i receive this error "dhclient is already running".the tap0 goes up normally but i receive this error when i attempt to get an ip.is there a simple way to get an ip?if i try to kill or restart dhclient when the vpn tunnel is up,all'interfaces lost theirs ip and network goes down crashing my vpn...
Is there anyway you can configure either OpenVPN client or the system to allow connections using OpenVPN to be made to computers on the OpenVPN network using their alias rather than their IP address. This may sound blasphemous but you can in Windows. That is if the VPN network is say 10.x.0.x I could connect to Comp4 or Comp2 using Comp4 or Comp2 not 10.x.0. 4 or 10.x.0.2 or whatever IP is allocated by the OpenVPN server. If the OpenVPN server has not been restarted then it will usually allocate the same IP every time the same client connects.
