Hi, I am trying to optimize my gigabit network. I have two Intel 1000 MT Gigabit Server Adapters, which support Jumbo Frames -- as well as a Switch that supports Jumbo Frames. However, I am observing some strange behavior in my file transfers from Windows XP to Linux and I am wondering if it has anything to do with the way the Samba variables are set on my Linux box? The "strange

Hello all, I got some severe iscsi connection loss on my dom0 (Gentoo 2.6.20-xen-r6, xen 3.1.1). Happening several times a day. open-iscsi version is 2.0.865.12.

I use bonding under CENTOS4.5 x32_62. I have these weird messages when I'm restarting network. Do you have any ideas how to fix this? (there is similar bug for centos5 http://bugs.centos.org/view.php?id=2404, but the author says that it worked for him in centos4...)

With the current talk on bonding, I have a few questions of my own. I'm setting up a KVM host with CentOS 6.3 x86_64 on which I'd like to attach the VMs to a bonded interface. My target setup is one where two GigE NICs are bonded and then the KVM bridge interface is attached to the bonded interface. Initially I tried to use the balance-alb mode (mode6), but had little luck (receiving

Hi, I am facing a problem when I run tc on the bonded nic cards. When I run tc on a single nic card, it worked perfectly fine. But when I run tc on a bond of two nics, tc gives poor performance. The two nics were bonded in round-robin (load balancing) mode. I created a qdisc, class and a filter as follows: tc qdisc add dev bond0 root handle 1: htb tc class add dev bond0 parent 1: classid

Has anyone successfully created a bonded interface (bond0) with say two nics AND also then aliased that interface to get bond0 and bond0:1 (for an alias ip) I just want to know if it's possible and reliable Thanks -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada

Hi, This may sound crazy but I will go ahead anyway. Here's my scenario: ifconfig bond0 10.10.10.1 netmask 255.0.0.0 ifenslave bond0 eth0 ifenslave bond0 eth1 brctl addbr stp0 brctl addif stp0 bond0 brctl stp stp0 on Is this a valid scenario? I am trying to bond two interfaces and run STP over the bonded interface..The problem I am trying to solve is to run STP over aggregated links

Hello, I have a server with 4 NICS running CentOS 5.2. I have bonded the interfaces together such that 'bond0' consists of eth0-3. This is not a problem, and works fine. However, I now need to create a virtual interface. In a non-bonded server I would just create something like eth0:1, but with a bonded interface I am a bit confused. I have created bond0:1 simple by copying the

Hello everyone I am running into some strange issues when configuring networking interfaces on my physical server running Centos 7.5. Let me give you an overview of what's going on: We have a physical server, running CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of

Hello All, I was curious to know if I can do traffic shaping on abonded Interface? Ex: I have to interfaces eth1 and eth2 which i have bonded together as bond0 , now the question is can I do shaping on eth1 and eth2 ??

Hello All, I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content. When the

I was given the challenge recently of creating a LAN-LAN bridge between two buildings several hundred metres from each other, using only existing Cat 3 wiring and without having to resort to an expensive and finicky 5 Ghz wireless link. I was able to create a 90 megabit link for about $3,000 Cdn with new PC's, CentOS 4.1, and the newly avaliable Black Box VDSL Ethernet Extender, which

Hi! I just upgraded a machine to 7.7.1908 and the default route is not being set on boot. This particular server has a bonded interface, and the corresponding configuration for the master is ( /etc/sysconfig/network-scripts/ifcfg-bond0): TYPE=Bond BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes NAME=bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.3.20.131 PREFIX=24

I'm running into a situation where a bogus bonded interface named "bond0" is being created, in addition to the desired "bond2" interface. Can anyone confirm this? Anyone know why it's happening or what I do to get rid of it? I wanted to start my numbering scheme at 2 instead of 0, which I didn't think would be a problem. As you can see, I have no reference

Hi, I am currently struggling with the right way to configure a bonding device via kickstart (via PXE). I am installing servers which have "eno" network interfaces. Instead of the expected bonding device with two active slaves (bonding mode is balance-alb), I get a bonding device with only one active slave and an independent, non-bonded network device. Also the bonding device
