Networking :: IP Layer Link Aggregation Without Switch Support

Sep 2, 2010

I'm looking for a way (kernel patches, configuration, etc) to bond multiple network interfaces together but for limited purposes. Here's the setup. Machines A, B, C, and D each have 4 NICs, each of which are on separate unmanaged switches. The connections are made in a corresponding way. e.g. eth0 of each machine are connected via switch 0, eth1 are connected via switch 1, etc. There are also other machines which have only one NIC and are connected to switch 0 only. All NICs for A/B/C/D and the switches are gigabit speed. The remaining machines have a low traffic level. Machines A/B/C/D need the extended bandwidth. And this bandwidth need usually involves only one connection at a time.

E.g. machine A transferring files to machine C with no other traffic going on. The speed need is to cut the transfer times from several hours to few hours (such as 8 hours to 2 hours). Transfers of up to a few terabytes at a time are involved. IEEE 802.1AX won't accomplish this. It requires special support from a single switch that all connection go to (raising costs and reducing reliability). Also, from technical details of 802.1AX, it appears that a decision process is made for which traffic goes over which physical link based on destination information. It's unclear what impact this will have, but it looks like at least a single TCP connection cannot use all physical links.

And possibly all traffic from host A to host B is limited to a physical link (not any better than a round robin of crossover cables). What I am looking for is something that works entirely on an end-to-end basis within a LAN. If it works at the link layer, that could be OK as long as it doesn't have the limitations of 802.1AX. Working at the IP layer would be OK, too (as I can already envision the logic of how to make that work). This might be an experimental patch to the Linux kernel if anyone has tried it. I have not dug into kernel source to see what might be in there, yet, but will eventually do that if there isn't a patch already available.

Networking :: Bonding Bond Running 802.3ad Dynamic Link Aggregation

Aug 20, 2010

Is it possible to bond an existing bond. I have 4 nics assigned to 2 bonds for link aggregation. ie

e1000g0 - bond1 - mode =4
e1000g1 - bond1 - mode =4
e1000g2 - bond2 - mode =4
e1000g3 - bond2 - mode =4

I would have presumed that you have 2 x agregates giving 2 x 2gig links and the resilience is that if one nic fails in either bond you carry on with that bond running a 1 gig link until fixed. But, our architect wants to have an active/passive (mode 1) accross bond2 and bond3. I have setup tons of mode 1 bonds and mode 4 bonds but never tried bonding 2 x mode 4 bonds!

Networking :: Ethernet Bonding - Link Layer Detection Failover Not Enough

Jul 7, 2011

We run redundant switches that two nic's on each server connect to. We also run bonding on our servers. Because we have two switches, we can't run lacp or anything. If a switch goes into a crashed state where it doesn't pass traffic but still provides link, bonding thinks the interface is still up and thus will still send traffic through it. Does anybody know a better way to configure the fail over of the interface? This would be a similar situation to somebody using a media converter.

Networking :: Channel Bonding Or Aggregation On Latest Fedora Release 14?

Nov 11, 2010

On my previous release *cough* if inenslave was needed, bonding instructions didn't work through aggregation did.

cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto bond0
iface bond0 inet static
address 192.168.1.149
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 127.0.0.1
broadcast 192.128.1.255
post-up ifenslave bond0 eth0 eth1
pre-down ifenslave -d bond0 eth0 eth1

#auto wlan0
#iface wlan0 inet dhcp
#netmask 255.255.255.0
#wpa-conf /etc/wpa_supplicant.conf

For some reason the unmentioned former disto, I could not get wireless networking under this configuration and a simple wlan0 interface, in case either cable were to sever it would retain a wireless. The bonding was done for speed, and I believe I can't get faster than mode=4.

Networking :: Link Aggregation Using Two Different NIC Types

Mar 21, 2011

I'm setting up link aggregation. When I use two ports of the same nic everything is working fine. When I use two ports of different nics (broadcom and intel) it doesn't work. Does anyone know of limitations using two different nics for link aggregation?

Ubuntu Networking :: Install Driver For Ethernet Card TP-LINK TF-3239DL?

May 10, 2011

I have a dual boot on my computer - with ubuntu 9.04 jaunty jackalope on one side of the partition, and windows 2000 on the other. I recently bought - and had installed - a new ethernet card: TP-LINK network adapter TF-3239DL. It works perfectly on windows, but not on linux. I understand that the problem is that I need to install the linux driver, which I have available (comes in the CD), but I don't really understand how I am supposed to proceed. The instructions are very unclear to me, and I have relatively little experience.

Ubuntu Networking :: Two Ethernet Ports And Share Internet Via A Switch

Apr 30, 2011

Just recently got a new rig, and was wondering, is there a way to share internet via a switch. I understand the problems with switches is that they dont assign IPs like routers do, but if my ubuntu machine worked like a router by assigning IPs, could it work? Current setup is as such. I have one ubuntu machine with 1 ethernet port (this shall be the main preferably) 1 mac with a single ethernet port 1 modem with a single ethernet port that cannot assign more than one IP address. And a 5 port switch. Would it be possible to place the modem into the switch, get the ubuntu machine to receive the IP address, and broadcast all other address' to everyone else via the same switch and ethernet cable?

Software :: Click On Email Link Not Switch Over To New Firefox Window

Jul 20, 2010

I am running KDE 3.5 Hardy Ubuntu and have encountered an odd window switch to new window view problem. When I click to open a web link in any Thunderbird email it will open Firefox but it stays on the current Thunderbird window. I have to manually click the FF on the task bar to switch and view it. Maybe it's a focus issue....not sure what focus really means. It also seems to do the same with other programs too.

Ubuntu :: Switch To The Audio Support That Was In 9.04?

Sep 29, 2010

10.04 doesn't support my father's computer. I always have to switch between 4.1 surround sound and 5.1. After I change a song, or watch another video, it only plays static, then I have to go into sound preferences and change it again, until the next song. I didn't have this trouble in 9.04 on his computer. The problem now is, he actually replaced windows with Ubuntu this time, so he wants everything to work. So what software was installed in 9.04 and how do I get it to 10.04?

CentOS 5 Hardware :: D-Link WUA-1340 Support - Rt73usb

Dec 30, 2008

CentOS 5.2. I have D-Link WUA-1340 wireless USB adapter that uses the rt73usb driver / module. At least I worked in Fedora 9 out of the box with that driver / module. I assume the Fedora 9 kernel supported it.

I really do not want to try and add a custom kernel to my instalation but I am wondering how I can get this to work on centOS 5.2.

I know first step is to get the adapter to be recognized by the system kernel. I think I can configure the network after that.

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]...

Ubuntu Networking :: Mount To Vista Needed For Apache - Symbolic Link Not Allowed Or Link Target Not Accessible

Apr 26, 2010

I have a problem where I'm using Ubuntu linux to mount a Windows Vista machine's USB drive and access it on the web using Apache. I did have the USB drive plugged into the Linux machine directly and that was working via the web. FollowSymLinks is on in httpd.conf

[Code]....

The mount works and I can see the files (see above) from my regular linux user account. If I make a test file in /mnt and soft link to that, I can see it on the web. So it's just the mount to the vista machine that seems to be a problem. It's supposed to be a simple read-only mount and the apache login should (I think) be able to see the same generic root access permissions.

log from apache: [Mon Apr 26 20:39:42 2010] [error] [client 99.99.99.99] Symbolic link not allowed or link target not accessible: /home/user1/pub_html/Music, referer: https://xx.xx.xx/~user1/music.html

The credentials have a login and password that matches a special read-only account on Vista. I can see the files on the system from Linux, but not via the web. As mentioned above, a different link to the same /mnt area works fine via the web. I've tried several different mount options with no success.

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
