I have 4 DSL modems connected with 4 different ISP's my scenario is

a) My FC-2 machine with LAN IP=192.168.10.1 and Bond0 IP=192.168.1.1
b) Modem-A LAN IP= 192.168.1.2 , ext IP=xxx.xxx.xxx.xxx
c) Modem-B LAN IP=192.168.1.3, ext IP=xxx.xxx.xxx.xxx
d) Modem-C LAN IP=192.168.1.4, ext IP=xxx.xxx.xxx.xxx
e) Modem-D LAN IP=192.168.1.5, ext IP=xxx.xxx.xxx.xxx

Modem-A, B, C, and D LAN connected with my FC-2 machine, and all 4 interfaces of my machine are in Bond0, Now please help me what default Gateway I should set in my FC-2 machine?>??? or I have to set 4 gateways in my machine?and will this configuration works?

General :: Binding Interface Per Core?

Jul 20, 2011

I just wonder, is it possible (using Linux 2.6) to limit overhead done by ethernet interface to one specific core. Ie. I have core2duo CPU, and two ethernet interfaces: eth0 and eth1. Is it possible to move system load caused by packets comming on eth0 to CPU0, so the other core (CPU1) will be idle?

I've got a server that has bond0 and bond1 setup. I'm documenting some things in case I need to failover and bring up my secondary server up as primary... I just need to know if simply creating the interface ifcfg-bond0:0 with a new IP address obviously of the crashed system,,, is all that needs done or do I need to load bond0:0 module in /etc/modules.conf also?

Ubuntu Installation :: Bonding Multiple Wireless NICs?

Nov 20, 2010

I have an Asus R1F laptop with a build in wireless card. I also have 2 USB dongles that we used to use old desktop machines. All of the cards work fine in Ubuntu. I'm running Ubuntu 10.10, 2.6.35-22-generic-pae.

The problem is that I have really bad signal on my side of the house and the connection is dropped quite often. I've tried just connecting on the devices at the same time, they all connect fine but nothing actually works. I read about bonding interface cards on this blog and that would solve all my problems - if a usb dongle could act as a backup for when the normal connection is dropped and while it is reconnecting.

I tried what was written and also did some Googling, but every way that I try seems to work fine until 2 wireless devices are bonded. When that happens they both disconnect and reconnect like crazy. This happens both with and without network manager running.

Build in card[wlan0]: Intel PRO/Wireless 3945ABG
USB[wlan1]: Cisco LinkSys Compact Wireless-G USB Adapter
USB[wlan2]: Realtek RTL 818713 WLAN Adapter
I load the module:
Code:
modprobe bonding mode=1 miimon=100 downdelay=200 updelay=200

Mar 4, 2010

I have to implement hardware redundancy.I have 2 linux machine for this and each have similar configuration/hardware. Lets say two machine Linux1 and Linux2. Currently Linux1 have one NIC and it has 4 IP address bind on it. Now I have to down the Linux1 and up Linux2 with same Ip addresses.

Could it possible to configure all the Ip (same)address on both Linux1 and Linux2 and Linux1 have eth:x status UP while Linux2 have eth:y status down.

I am trying it but on Linux2 machine I cant able to create multiple Ip interfaces with down status.

Networking :: Multiple NIC's And Determining The Correct Interface?

Feb 8, 2010

I have two NIC cards installed, they both go to seperate networks. Occassionally I am not able to establish a connection via eth1. When looking at tcpdump traces I see that Linux is using eth0 hardware port and putting eth1's IP address in the packet to reply to the connection request. When the connections work its when Linux uses eth1's port.

Ubuntu Networking :: Split Video Stream Across Multiple N/W Interface?

Sep 15, 2010

I want to do a video streaming to a remote PC across the internet. The video bitrate is around 600 kbps. But my internet connection supports only a maximum upload bandwidth of 400 kbps.So I thought I will get one more connection and use the combined upload b/w of 800 kbps to stream the video. I hope there should be a way to split the stream across two interface and merge them together at the remote endpoint. All this has to be done at real time.

Ubuntu Networking :: Alix 2d13 - Multiple Network Cards - Unable To Bind More Than One Physical Interface?

Jun 2, 2010

I have a strange problem regarding networking on the Alix 2d13 running Ubuntu 10.04. The Alix has 3 physical network interfaces, lspci says:

Code:
00:09.0 Ethernet controller [0200]: VIA Technologies, Inc. VT6105M [Rhine-III] [1106:3053] (rev 96)
Kernel driver in use: via-rhine

Kernel driver in use: via-rhine
Kernel modules: via-rhine

[Code]...

It seems, if more than one cable is connected, a random hardware port is chosen as eth0-eth2. If only one cable is connected the port that is connected is chosen as eth0-eth2. Any idea what's going wrong here?

Ubuntu Networking :: LAG Instead Of Nic Bonding?

Feb 16, 2010

I've run across a few threads in the archived forums regarding nic bonding. I could be wrong but I imagine most of the people that are looking at bonding are probably really wanting what they would get out of creating a LAG between their Ubuntu Server and a managed switch capable of LACP trunks. If you have two NICS on your ubuntu server and want 2gps throughput & failover check out the page on creating a LAG. Obviously this requires your switch to be compatible though. [URL]...

I connect to my corporate LAN(dhcp) using a wired connection and also connect to a WLAN(dhcp) without various constraints applied by the wired connection. In short my wired connection blocks outbound ssh traffic to my server at home. My WLAN connection is pretty lax so ssh connections to my home webserver can be made using the wireless connection.Can I route ssh to that particular ip via my wireless connection?

Networking :: 802.3ad Bonding Not Using All Interfaces Equally

Apr 14, 2011

I am seeing an issue on a few servers where it doesn't appear all NICs in the 802.3ad lag are all operating at the same level. A few of the servers have two bonds each with two NICs in each bond.I have two NFS servers that each has 1 bond with 3 NICs.All are RHEL5 x64 2.6.18.I think the reason why I see one interface dominating RX and another dominating TX is due to the xmit_hash_policy but there are three hosts that use this particular server for network traffic.That's 3 different physical mac addresses.The layer2 algorithm should be fine in that situation I would think.Would I just be better off with balance-rr?

CentOS 5 Networking :: Bonding Or Bridging?

Jul 19, 2011

I am confused as to what is going on with a particular box that I am working with.As you can see in the attached ifconfig print out, one eth port is basically only used as a output while the other is only really used as an input.I connect to the box via 10.20.40.104 for ssh,ftp,http,etc.I just want to know the name of what is happening (is it bonding,bridging?) and maybe some information about where it is configured.I looked in modprobe.conf

eth0 Link encap:Ethernet HWaddr 00:1E:C9:EE:5A:91
inet addr:10.20.40.105 Bcast:10.20.40.255 Mask:255.255.255.0

Ubuntu Networking :: NIC Bonding - Teaming And Switches ?

Jun 20, 2011

I have a question about bonded NICs and the switches they are connected to.

I have a server which needs to send a lot of data to another server quickly. Both have multiple GbE NICs. I understand what is required at the server end (I think) in that a pseudo-interface is created such as bond0 with the IP applied to that interface rather than eth0 and eth1.

My question relates to the connection between the servers, i.e. the switch. Is a specific type of switch required for this to work, as an IP will have 2 (or more) MAC addresses associated with it, or how does the switch decide to which port to route the traffic for the bond0 IP?

Also, will this only work when multiple connections are being made? What I mean is, will each individual TCP connection only use either the physical eth0 OR the physical eth1 interface, or can a single connection make use of the aggregated bandwidth, sending one packet to one physical interface and another to the other physical interface, using the bond0 IP as the destination?

What I am trying to work out is if I had a storage server connected to an application server and exporting storage using NFS or GlusterFS, would an aggregated link improve throughput?

Networking :: Network Bonding Citrix Xenserver

Apr 16, 2010

As Xen is based on LINUX I'm hoping that someone out there could help me. I'm struggling with 802.3ad on a cisco switch (LACP). I'm going to be using this for my storage network on a dedicated cisco switch talking to a teamed pair of intel NIC's ISCSI storage. From the intel side I can set them to Link aggregated one team 2GB this is fine and my config shows active active on the NICs. How would I go about doing this from a LINUX box. In order to remove any bottle necks it needs to be active active from Xen. If I do a pif-forget uuid= on a XEN server I'm in complete control using Linux.

Networking :: Vhost With Reverse DNS On ADSL2 Connection Not Binding

Mar 22, 2010

I'm working on an ADSL2 connection that connects via PPPoE and it is assigned a static IP. On top of the static, the ISP has assigned a small block of 6 useable IP addresses.

- The primary static IP is on the interface ppp0
- The other 6 IPs are configured as eth0:1, eth0:2, eth0:3 etc.

With the above setup all IPs are reachable and useable on the internet.

- The revers DNS has been updated for a few of these and resolves with no problems. ie: eth0:1 has the 123.123.123.123 IP and resolves to blah.host.com and blah.host.com resolves to the IP address.

- To test this I have tried a program like BNC to bind to the IP address on eth0:1 but for some reason when connecting externally the host address is coming up with the FQDN on ppp0 interface IP, not the vhost IP.

Questions is, is this the normal behaviour since its a PPPoE connection and would only work if the ISP supported a bridged connection? something on the ISP end not allowing this to work?

Ubuntu Networking :: 10.4 - NIC Bonding - Make Routes Behave Themselves?

Dec 3, 2010

I just set up NIC bonding in Ubuntu 10.4, following these instructions, and I've got it working except for one problem: Every time I up or down a network device, or every time the system reboots, my routes go all to hell with eth0 and eth1 entries next to my bond0 entries. When the eth0 and eth1 entries show up, my connection is hosed and I have to go in via the maintenance IP to kill each route one at a time, leaving only bond0. Here's how I want my routes to look at all times:

Code:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.87.9.0 0.0.0.0 255.255.255.0 U 0 0 0 bond0
0.0.0.0 10.87.9.1 0.0.0.0 UG 100 0 0 bond0

Networking :: Bonding Of For Fault-tolerance (active-backup)?

May 14, 2010

Just for the learning sake, I was going through this document for Bonding of Two Ethernet Cards for Fault-Tolerance (active-backup). Here, /etc/modprobe.conf is as

Code:

alias bond0 bonding
options bond0 mode=1 arp_ip_target=192.168.1.1 arp_interval=200 primary=eth0

Now, I just wanted to to know,

- What parameter is arp_ip_target and why it is used.

- Why the IP is 192.168.1.1, whereas the IP in /etc/sysconfig/network-script/ifcfg-bond0 is 192.168.1.5.

- Can I use the below /etc/modprobe.conf ?

Code:

alias bond0 bonding
options bond0 miimon=100 mode=1 primary=eth0

Networking :: Underwhelming The Routing/VLAN/bonding Performance?

Mar 10, 2011

Upgraded a school network from FastEthernet to GigabitEthernet. Broke the network up into VLANs. Discovered that the router (Cisco 2821) could only route between the VLANs at around 400Mb/s. Tested out some layer three switches. They work very nicely, but are more than we need. So I started putting some spare equipment we had together as a Linux router.

Result: Underwhelmed. The machine has two Intel GigE interfaces. With the machine configured to route between two test VLANs I get about 855Mb/s with a single interface (all VLANs trunked over the single interface). That's about what I'd expect. Maybe a little low. With the two interfaces bonded, I get about the same.

For testing, I set up eight Windows machines, four on each VLAN. The Linux router is the only machine that can route between the two VLANs. I used Iperf to generate traffic and measure throughput between pairs of machines. Two machines on the same VLAN get about 300Mb/s between themselves. With the four machines organized into cross-VLAN pairs, I get about 855Mb/s total throughput on a single interface and very slightly more with two interfaces bonded.

The Linux router has an Intel Xeon E5506 CPU running at 2.13GHz and these are Intel GigE interfaces (built-in). I would expect to get a large boost by adding the second interface. I've confirmed that bonding is working (by pulling either of the cables and watching everything continue to function).
