I followed this tutorial => https://help.ubuntu.com/community/OpenVPN
I'm working on ubuntu 10.10 OS
So everything is ok when i start the tutorial with my interface on code...
The only way I can make it work again is by setting the interfaces back to
auto lo
iface lo inet loopback
>> then reboot
and after that put back the br0 settings in the interfaces en restart the network.
I am trying to set up bridge, and everything seems to be ok, except 1 thing, it disappears after reboot. So, what I am doing:
Code:
brctl addbr br0
brctl addif br0 eth0
and adding /etc/sysconfig/network-scripts/ifcfg-br0, here it is:
Code:
GATEWAY=192.168.1.1
DEVICE=br0
BOOTPROTO=none
NETMASK=255.255.255.0
DNS1=208.67.222.222
DNS2=208.67.220.220
TYPE=bridge
HWADDR=00:18:f3:75:18:78
IPADDR=192.168.1.3
IPV6INIT=no
ONBOOT=yes
USERCTL=no
and my ifcfg-eth0 is:
Code:
GATEWAY=192.168.1.1
DEVICE=eth0
BOOTPROTO=none
NETMASK=255.255.255.0
DNS1=208.67.222.222
DNS2=208.67.220.220
TYPE=bridge
HWADDR=00:18:f3:75:18:78
IPADDR=192.168.1.3
IPV6INIT=no
ONBOOT=yes
USERCTL=no
How to make it working after reboot?
I'm following this guide [URL]. I am trying to use a bridge to vpn from work to home.
/etc/network/interfaces
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto br0
iface br0 inet dhcp
bridge_ports eth0
iface eth0 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down
I am forced to use dhcp because of my router. (although it is a static lease) I think this is where I am hung up. Everything else seems to be working properly though. I have a windows client connecting but is limited to the server serving out openvpn. (192.168.1.21) In other words it is not functioning as a bridged vpn service.

I have OpenVPN running on my Ubuntu Server just fine. I can connect over the Internet and access all my resources on the LAN via bridged mode perfectly. My server only has one LAN card and sits behind my router, which means it has a private IP address of 10.1.1.2....Which brings me to my question. I want to open up access to my friends via OpenVPN, but I don't want them to be able to access other machines on my LAN (e.g. 10.1.1.20). However, I do want them to be able to talk to each other and pass broadcasts (old LAN games), as well as my laptop (let's say 10.1.1.7).I've tried using iptables to block traffic to the LAN (such as .20), to no avail. I've been reading up and it seems as though iptables won't even filter the traffic, as it's passed at a lower layer. Is this true? If so, what do you recommend I do in order to prevent my buddies from accessing the rest of my LAN while siumultaneously allowing broadcasts pass for some very old Windows LAN games (we're talking Windows 9.
View 2 Replies View RelatedI 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 want to set up a bridge using bridge-utils within /etc/network/interfaces like is shown here in this guide: [URL] The problem is that, at the same time, I want eth0 to have a specific static IP address. Right now I have a configuration for eth0. This guide tells me that I should not configure eth0 outside of the br0 configuration.

I'm a new user of Ubuntu, so i'm not that familiar with this OS. My wireless network is detected but when I'm entering my 128 bits WEP key, it doesn't connect at all. I have no clue where to start troubleshooting.
Here's some of my specs if that's of any help:
Computer is a Sony Vaio laptop model VGN-SZ370P
My wireless card is from Intel Corporation 82801G (ICH7 Family) USB UHCI Controller
The ethernet cable connection used to work before, but I fooled around with some commands and now seems to be disabled...
I wireless network card is Broadcom Corporation BCM431, but is doesn't work after I update kernel from
2.6.29.6-217.2.7 to 2.6.29.6-217.2.8.

A couple of weeks ago I was using openvpn with a provider of PVNs on a home wifi network with no problems.I had installed openvpn using apt-get install and downloaded theopvn PVN files from the organization.erything worked fine.I would type sudo openvpn nameoffile.ovpn and then add my username and password during the installation process.However, when I try to do the same on an Ethernet network, the installation work fines (as above) and informs me that everything is connected (same as on the home Wifi network) but Firefox and all other software cannot connect to anything on the Internet.I contacted the organization who said the DNS was a problem and I needed to install resolvconf then modify each .opvn file using up /etc/openvpn/update-resolv-conf and down /etc/openvpn/update-resolv-confcauses the installation to hang because it does not like openvpn pointing to an external file.Irrespective of the problem I have with this "solution", previously I could use openvpn without modifying the .ovpn files. It just worked! I wonder if anyone knows why using the exact same configuration on an Ethernet network (which I have not used before with openvpn) is causing problems

I can get the VPN server running and everything connects fine from the client. I just don't know how to tunnel all the traffic through the VPS because it involves making the bridge which I'm having trouble with. What exactly am I supposed to put in /etc/network/interfaces?
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 currently got a Xen box with 3 Virtual machines on it, in a routed setup. I'd like to put them all on a private internal network as well, which I'm assuming I'd do with a dummy network card and a xen bridge, but I can't find any information about setting up the xen Bridging setup on top of the existing network-route instlal.

View 2 Replies View RelatedI 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 am running ubuntu 9.10 on a dell xps m1530 laptop dual booting with windows 7. I am trying to achieve the following setup.
Wireless router <=========> Laptop <-----> Switch <-----> PS3
---- wired
==== wireless
Both laptop and ps3 have static ip addresses
The reason for this is I can connect to the internet on my ps3 through my laptop, and I can stream from my laptop to ps3 through wired connection. This works fine in windows 7 all I had to do was right click bridge connections. As I dual boot I don't want to have to make any changes to the settings on the ps3.
My interfaces are:
eth0 - wired
wlan0 - wireless
I installed bridge-utils and created a bridge and added both eth0 and wlan0 to it. However I could not get it to work. I have also tried internet sharing through network manager and firestarter.
I setup a network bridge on pc A, with windows 7 installed on it, using windows default bridging tool. I connected computer B to computer A and Im trying to connect to the internet through the network bridge on computer A. Computer B (client) has two OS's installed, win XP and linux(tried with different distributions, didnt work). On windows XP everything is working, when i try to ping the router (after computer A) it also responds. On linux system nothing is working, and im not quite sure why.
I set up linux to receive IP adress from DHCP, which is router in this case (behind computer A), same way windows XP was configured. I decided to ask here, because I couldn't find anything on the net. My guess is windows-made bridge supports only windows-OS's but that would be kind of strange (its just a software bridge).
I have installed CentOs 5.4 for Snort sensor , on the location where i intend to place the Snort sensor to listen for internal firewall leg (LAN) the switch doesn't support port mirror so i would like to create with 2 nic's bridge and pass trough the firewall internal leg my question how do i set such configuration.
View 2 Replies View RelatedI am trying to set up a network like this:
Internet <---> Router <---> Debian server <---> Windows PC
I want the server and PC to both have internet access, and I want to be able to forward ports from the router to the server. I know how to configure the server to give the PC internet access, but how would I assign an IP address to the server and give it internet access? I have used a very similar setup a few years ago, but I can't remember how to do this.
That the Linux bridge configuration does not work afer I upgraded the kernel to 2.6.33.2. Why I can't find the device vmbr0?

I've seen this issue and it never seems to get resolved maybe this time I can find a fix.I'm currently using ubuntu 11.04 although i've had this issue since 10.04 and 10.10When using openvpn in windows it works perfectly fine but when using openvpn on ubuntu that's a completely different story I import my .ovpn file from clearos it loads the keys just fine but when it tries to connect it say's "no valid vpn secrets"
On clearos it gives you 3 certs and a .ovpn file the file sets it to use password with tls certs but it still comes up with this error, i've been quite stumped and it would be nice to possibly shed some light on this so I can finally get ubuntu to work with openvpn if possible.
my problem is following: I'm running a bridged OpenVPN on my Debian. If the service is running, everything works fine: local and Internet, ftp, mailing from in and outside etc. But, when stopping OpenVPN, sending mails from inside (LAN) fails: I cannot reach smtp (postfix) listening on port 465. And even reaching mailboxes using IMAP gets horribly slow eg. in Thunderbird. Here is my firewall.sh script.

How do I configure a network bridge to start on boot?
I have two network interfaces eth0 and eth1.
Here is my current network script configuration:
Code:
#/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
HWADDR=00:10:18:4e:5e:a7
[Code]....
The bridge will come up if I restart the network service after boot....but it won't automatically come up when the computer starts.
I set up a virtual bridge for a virtual machine (qemu-kvm) using a qemutap interface:
Code:
# brctl show
bridge2 8000.0022648a3dcc no eth5
qemutap2
I can ping and ssh to the server ...
Then I try to copy (scp) a file (2.8 M) to the server and, near the end, the copy stops and the server stops responding to ping and is not able to ping nothing except itself.
"ifconfig down ; ifconfig up" and the server is on line again.
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 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:

I am trying to have accessible computer by its network name (same as hostname) by ping and Samba client from other computers and one directory shared on my laptop. I simple, trivial wish I hope. Nothing extravagant. Something what every Windows user has out-of-the box, just to select a shared directory. However I struggle hard to do the same with linux. Sharing directory with samba is relatively easy, the issues I have is with my laptop network name. It is not recognized/propagated to the local network.
I cannot rely on static data in /etc/hosts. This is a laptop not a server, I move it between different networks. To achieve propagation of my network name (hostname) dynamically, so everyone in the local network can at least ping me, I was advised to use winbind (winbindd), that is to rely on MS NetBios technology There is no native linux technology to achieve this? shame! what about plain/dynamic DNS? why it is not my network name not propagated to my local DNS server/wifi/rooter?
To do that I was advised to do:
- run winbind service (winbindd daemon)
- run samba service (umm, not sure if this is necessary for network name propagation, but I also want to share data so lets keep it as an essential).
- add "wins" to /etc/nsswitch.conf to "hosts" section
Well, it seems to work on my other two computers with Ubuntu and Mandriva well. But not on Suse. Well, not completely, not permanently. It magically start working when I call "Yast -> Samba Configuration". No change here (everything is already set: Domain Name, Not a DC, Netbios Hostname, Wins server support=yes, use Wins for Hostname Resolution) just hit OK. It runs SOMETHING in the background (some scripts) for a few seconds. And then abrakadabra, everything is fine, my network name is recognized, everyone can use my samba exposed directory, smb4k sees me in the Network Neighborhood.
BUT when I restart, I am "back in square one". Pinging my name does not work, smb4k does not see me, or cannot find me even by IP! Samba sharing works by using direct IP. Not all clients support connecting by IP notably not smb4k. To use Samba properly you have to sort out network name visibility fist. I would like to make "Yast -> Samba Configuration" achievements somewhat more PERMANENT.
What exactly runs when I hit OK? No new server/daemon was started. I checked PS, nothing with newer PID appeared. And samba and winbind are started on boot, they were running indeed. No change in configuration was made. I checked all changes made in /etc - but none found! Where is winbind configuration? smb.conf? Do I need to run wins server/client, another daemon?
I set up a bridge device but I can not figure out how to pass parameters into the ifcfg-vmbr0 in particular I need to pass:
maxage
ageing
fd and stp seems to be passed by DELAY=0 and STP=on the others? I have not found anything in the post, tips, docs how could I do?
