Networking :: Setup A Bridge Using Bridge-utils Within /etc/network/interfaces?
Dec 8, 2008I 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.

Fedora Networking :: Network Bridge Setup Disappears After Reboot
Nov 18, 2009I 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

OpenSUSE Network :: 11.2 Xen Bridged Networking - Setup Multiple DomU Through The Default Bridge Setup
Feb 4, 2010Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

Networking :: Creating Bridge And Adding LAN Interface
Jun 28, 2009Setup : internet -- VirtualBoxHost -- WIFI-switch -- clients
VirtualBoxHost hosts several Virtual Machines and has 2 interfaces. Wan-interface is not used by VirtualBoxHost, but is directly mapped to the Virtual Machine Endian Firewall.
What I want:
Access to VM's for the Wifi-clients AND access from WiFi-clients to VirtualBoxHost.
What I have tried:
- create bridge
- add LAN-interface to bridge
- create tap0
- add tap0 to bridge
Virtual Machine uses tap0
Wifi-clients are connected via LAN-interface, via bridge, to VM's. But my host-machine is not accessible from a WLAN-client and also I can not access a VirtualMachine from my host-machine. A WLAN-client can connect to a VirtualMachine without problem. I think with my bridge the local LAN and the VM's are now connected. How to put also my host-machine in the LAN? As a LAN-client.
Networking :: Transparent Router / Bridge - Ppp Interface
Jul 27, 2010The challenge: I am trying to setup a piece of hardware that is transparent to the network that transfers ip packets between two interfaces without adding a "hop". Details The particular problem I'm having is that one interface is ppp, the other is ethernet. It is trivial to setup a bridge between two ethernet devices but I am having trouble finding anything for ppp<->ethernet.
Here, the ppp link is an internet connection, and the ethernet connection has exactly one device attached. Once the ppp link is negotiated, I want the ppp peer to think it's talking directly with the device on my ethernet interface and I want the device on my ethernet interface to think it's talking directly to the ppp peer.
Current solution: The best solution I currently have is to alter the routing table. When the ppp link is negotiated, I am given an ip address. I add a route that directs everything to that ip address to the eth0 device. I also set a default route to the ppp device. Now, anything that comes from the ethernet side gets forwarded to the ppp side, and anything directed towards my ip address gets forwarded to the eth0 side.
Server :: Creating Bridge Between Ad-hoc And Wireless Interface
Oct 20, 2010I was wondering if I could create a bridge between two wireless interfaces. So that when there is a WAN that filters MAC's, 2 different computers which aren't in the WAN white list can connect to the WAN via me. Is that possible? And how?
View 4 Replies View RelatedNetworking :: Adding Two Interface Cards To Bridge - No Connectivity
Mar 1, 2011I have a network config as follows:
X.8 <---> X.41 X.40 <--->X.16
where X.8 and X.16 are 2 separate workstations and X.40/X.41 are two interface cards in the same machine. Now I apply brctl bridging in the X.40/X.41 machine by adding both the interfaces to the bridge and thereby connecting X.8 and X.16. This part is working perfect. But there is no connectivity between X.8 and X.41 and when I try to ping at X.8 to X.41 it gives Destination Host Unreachable. Is there a way to achieve this since I require some message to be sent from X.8 to the X.40/X.41 bridge machine.
Security :: Mount 2 Network Interface Card (NIC) And Make A Bridge
Apr 1, 2010Actually i'm doing an ingenior training in SAGEM company, well i'm trying to develop an application which is able ti disturb the IP Network,my idea was is to mount 2 Network Interface Card (NIC) and make a bridge to pass the IP flow and to exploit the firewall Netfilter using iptables command.The application has to import a text file containing a binary array like this one:
0 1 0 : 0 corresponds to iptables -p ip ACCEPT
1 1 1 : 1 corresponds to iptables -p ip DROP
0 0 1
==> So the expected result is to have 5 ip datagrams dropped
My idea was: if 0 --> iptables -A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
if 1 --> iptables -A FORWARD -p ip -m limit --limit-burst 1 -j DROP
The problem was: After executing the application and parsing the text file,
with iptables -L -v: i have
Code:
-A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
-A FORWARD -p ip -m limit --limit-burst 1 -j DROP
-A FORWARD -p ip -m limit --limit-burst 1 -j ACCEPT
which is logic, but when i sniff with wireshark i find more packets are dropped(6,7 or 8 are dropped), like i had put more DROP rules. and sometimes i found the exact value(usually 5 dropped).
Ubuntu Networking :: Samba With Bridge Interface / Cannot Assign Requested Address?
Sep 17, 2010I have two network interfaces in my pc eth0 and wlan0 and a virtual one br0.
router <= eth0 (0.0.0.0) => br0 (192.168.1.10) <= wlan0 (0.0.0.0) => other pc.
On startup of my pc (ubuntu 10.04 server x64), samba bind itself only to loopback network interface, as i can see when i do netstat -an , preventing me to enter in my shares from a remote pc.
Here is my configuration regarding samba network:
Code:
interfaces = 127.0.0.0/8 192.168.1.0/24
bind interfaces only = yes
and my /etc/network/interface
Code:
# The loopback network interface
auto lo
iface lo inet loopback
code....
Any idea fo speed up my bridge configuration or to force samba to wait unitl the bridge is ready?
Fedora Servers :: Nagios Web Interface Setup
Jul 25, 2010I'm trying to setup nagios, and I've looked at several guides but none of them seem to address my problem.Here's the clearest guide that I followed URl...I followed all the instructions on that basica guide, except disabling SELinux. I changed SELinux rules based on URL...I'm not getting any AVC Denials, so that's not the problem. Nagios and Apache both start fine. If I go to my local IP, I get the standard Apache test page. URl...(address from all the guides I read) doesn't resolve.I know that Nagios is at least running from "service nagios status," and I have gotten two alerts emailed to me: swap alert (I don't have swap configured) and disk space.

View 2 Replies View RelatedNetworking :: Two Nics Setup With No Bridging But Still Seem To Bridge?
Jun 29, 2010I'm trying to setup a Centos box to act as a backup server for our intranet between stores. I have two interfaces in it, the first one is currently connected to my local network and is using dhcp to get its ip address and such, the second one is set to a static ip address and is connected to an independent network that just has a DigiBoard Portserver hooked to it and no connection to the regular network. What I am doing is using ssh to portforward the telnet port on this box to the main server so when you telnet into the box from the second interface using the portserver you get connected to the main server.
I plan on using this over DSL lines as a backup when our main dervice goes out to allow the portservers at the remote locations to seemlessly connect to the main server by just moving the network cable from the local net to the backup server. My problem is that when I have the everything working I am able to ping the second interface ip address from the normal network even though the secondary card does not in anyway externally connect to the network, this is a problem.
Eventually I want to duplicate the main server address so that the normal portservers and other terminals on the remote site will not have to be reconfigured to access the backup server. All I want is to be able to tell the managers is to switch a cable while the main connection is down and not have to manage a bunch of config files to get the store back up. Right now if I duplicate the main server ip address and it is accessible through the first interface I'm guessing I'll see all kinds of problems relating to duplicate ip addresses on the network. I've tried some routing and iptable stuff but I'm not real familiar with either so I had no luck. Is there someway to block the internal connection between the two interfaces so the only thing that sees the duplicate ip address is the second interface?
Debian :: Bridge Setup - Cannot Connect To Any Wireless Networks
Apr 12, 2011I am a (somewhat) newbie to Linux (but have an extensive Windows background), and I have just installed Debian Squeeze in an old EeePc 701 4G using the netinst version only with the following packages:
eeepc-acpi-scripts
x-window-manager
gnome-session
gdm
gnome-themes
gnome-themes-extra
plymouth
bridge-utils
Now I would like to install Debian in my main laptop, but I think it won't be able to connect to any wireless networks during setup and before installing firmware-brcm80211 and wireless-tools (its wireless card is a Broadcom 43224AG). That being, and to avoid connecting the computer directly to the router (it is not easy), I would like to bridge the EeePc's wireless connection to my laptop using a cable. I tried using the instructions found at the Debian Wiki, but I couldn't set it up properly.
Networking :: Setup Bridge Mode For Windows Server?
Mar 3, 2010 setup linux in bridg mode for my windows server ?
my both linux and windows has 2 network cards each.
basicaly it is vLan cards, each server has 2 network cards. one to main switch and one to local IP.
data will be going like below:
internet ----------------> eth0 --> linux --> eth1 ----------------> Windows.
i have vLans on both servers. And i need cross connection setup. And use linux in bridg mode / cross connection .
actualy i want to use Iptable rules to filter bad packets and forward good packets to windows. i have scripts how to forward packets to windows. but the problem is i dont know how to setup both servers in this topology. and how to make linux as bridge.
All it should be in transparent mode. Not in NAT mode.
Ubuntu :: OpenVPN Setup - Bridge Ports (From Work To Home)
Sep 9, 2010I'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

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.

OpenSUSE Network :: Adsl Modem Acting As A Bridge To My Router Setup - Connection - Internet Went Slow ?
Jun 19, 2011I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !

Feb 25, 2011I wanted to setup an ssh server on my computer that I, along with some other people I know, could access from outside my home network. I didn't want to give others access to my computer (even if that access was limited), so I wanted to setup the server within a Virtualbox virtual machine.
STEP 1: Create the virtual machine.Create a vm with the distro of your choice. I won't explain how to do that here since there are TONS of guides online about how to do this.
STEP 2: Configure the host to send info to the vm.I found an article that explains why you have to do this and how to do it:URL...I can summarize the article by saying that the vm is hidden from other network computers by the host computer. Therefore, you have to configure the host to send information received on a particular port (any port you choose greater than or equal to 1024 as explained in the above link) to port 22 of the vm (port 22 is the default port for ssh).
Server :: VPN Setup With Bridged Tap Interface
Aug 12, 2011I need some advice on setting up VPN. The situation is as follows:
Server => Centos 5.5
Clients => Fedora, Ubuntu, Win XP, Win 7 (and possibly mac)
The flow could be as follows
Code:
Client=>10.x.x.x=========>10.x.x.1<=VPN Server=>192.168.x.1<=========192.168.x.x<=Server in LAN
A bit of explanation of the above. I would like to allow any client (be it any Linux version or Windows), to connect to the VPN server, obtain an IP Address and then function as if it is in the LAN and be able to access all the servers in the LAN. So the connection between an external client and the VPN server will be through the 10.x.x.x ip range and the server and the internal machines will be through the range 192.168.x.x. After going through the internet, I have decided to deploy OpenVPN client/server, with bridged tap interface in the server and the client.
