CentOS 6.2......... Why do the physical interfaces report (correctly) that they're negotiated at 1000Mb/s, but when I `cat /proc/net/bonding/bond0` I get 100Mbps for the member interfaces, and when I ` mii-tool bond0` I get 10Mbps for the bond? ----------------------------------------------------------------------------------------- ethtool em1 Settings for em1: Supported ports: [

Dear All, I have an onboard Realtek RTL8111/8168B NIC. from lspci -vv : 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02) It is detected, but why the speed is always 100Mbps, already change cable but still no luck. I use ethtool and from the output it seems that system know that this NIC support gigabit speed : ???????

We have an HP DL360 server with dual on-board Tigon3 ethernet cards. We are using eth0, eth1 is unused at the moment. Sometimes when the network interface is under heavy load, for example moving large file transfers over rsync or NFS, the network interface stops working and we lose all connection to the server. The only solution at this point is to jump on the console and restart the network

I want to check the speed like features of my Ethernet in dom0 and domUs. But in virtualized environment it gives strange output why is that so? how to check it otherwise? Non-virtualized FC11 [root@fasiha home]# ethtool eth0 Settings for eth0:     Supported ports: [ TP ]     Supported link modes:   10baseT/Half 10baseT/Full                             100baseT/Half 100baseT/Full

Hello, Just did a fresh install of xen-4.0 and using the 2.6.31.13 dom0 kernel. I have 6 linux debian guests running, and on my host console i am getting these errors rolling pretty constantly. "Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet" I tried doing the ethtool -K eth0 tx off and same thing on peth0, using bridged mode for network config. Any tips?

anyone know how to force network cards talk at gig speeds when all it wants to do is establish a connection at 100mbits root at host1 [/backup/cpbackup/daily]# mii-tool eth0: negotiated 100baseTx-FD, link ok eth1: negotiated 100baseTx-FD flow-control, link ok 01:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5721 Gigabit Ethernet PCI Express (rev 11) Subsystem: Broadcom

I''m trying to build out a test cloud using XCP 1.0.0 beta with 3 machines of 18 cores total (Phenom II 1090s). I''ve built three machines, installed XCP 1.0.0 beta on them and they all three have the same problem - the Realtek network cards don''t work. The following is the output from lspci 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI

Hello everyone: Over the past few years I have been a happy samba user, running samba on Redhat / FC platforms. Recently I upgraded hardware, and Samba hasn't been performing well at all.. which makes me sad :-( The new hardware is Asus P5B board with a dual-core intel processor. This board has an onboard Realtek RTL8111/8168B gigabit ethernet controller, which was a hassle to setup.

Hi all, we recently moved our offices to a bigger place. Therefore all our servers and network electronic had to be turned off... :) Well, I know it sounds odd but after the move Samba is much slower serving the shares and users have to wait ages for the information to be copied or moved across the network. In some cases, Windows desktops seem to freeze until the data is retrieved from the

I have the xensource 3.1.0 x86_64 tarball installed over a RHEL5 clone distribution. The "ethtool" utility only returns the following information: [root@fermigrid5 etc]# ethtool eth0 Settings for eth0: Link detected: yes [root@fermigrid5 etc]# Since I have no vanilla-installed rhel5 machines with which to compare, I am not sure if I am dealing with a bug in the ethtool (whose

Hi folks on debian stable I've a default samba file sharing config.

I've got a pair of identical CentOS 6.7 servers, with SuperMicro X8DTE-F motherboards, these have 2 each Intel 82574L ethernet ports. The eth0 ports are plugged in with 10' runs of brand new cat 5e cable to a Cisco Nexxus 9000 switch (provided by the data center). These servers keep coming up at 100baseT rather than gigE. I've swapped ports and cables with a different server,

Hi List, I am running a x86_64 Centos server, after a reboot the network has decided to not work.. this particular machine has 8 eth ports eth0-7. eth0 and eth3 were bonded (mode 1 ) after reboot the bond did not work. It came up OK but no data was passing through it. all other interfaces on the machine were working. I decided to remove the bond, so after removing the bond i was left with eth0

I am trying to connect two workstations (CentOS 3&4) directly using a straight through cat 5e cable with a crossover adapter on one of the ends. Both hosts have gigabit-capable ethernet card. According to lspci host 1 has: 03:0e.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01) and host 2 has: 05:00.0 Ethernet controller: Marvell Technology Group

Last problem I had involved changing one character in my configuration scripts. Really easy once someone showed me what was wrong. Well I think this issue is just the same. The moment I used apt to install the Xen kernal and tools I lost internet connectivity. I have been managing because I can restore connectivity be deleting the bridge mpower@dodtsair:~$ sudo ifdown eth0

Hi! Maybe, I found a bug of xen. My system: - domain0 - gentoo - xen-devel-3.0, kernel 2.6.12.5-r1 - domain1 - debian - kernel 2.6.12.5-r1 (2 interface: vif1.1 = eth0 (0.0.0.0), vif1.2 = eth1 (10.0.1.1 + gw 10.0.1.2)) Bridge: xen-br0 (config as 10.0.1.2) include (vif1.2, vif0.0) xen-br1 (config as 0.0.0.0) include (vif1.1, peth0) On server domain1 I use a pppoe server.
