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: [

I have just noticed this message in my kernel logs, reporting the possibility of an error with my memory. This would go a long way towards explaining the problems i''ve been having. This particular error is occuring when i''m not running xen so is obviously not something brought on by xen itself. The strange thing is that the NMI error is always followed by the TLAN: eth0: Adaptor

Hi I have been trying to get Xen running under Ubuntu. Status ------ I can get Ubuntu to boot on the patched 2.6.10 kernel however :- a) I get several boot errors thus :- Linux version 2.6.11.10-xen0 (root@gateway) (gcc version 3.3.5 (Debian 1:3.3.5-8ubuntu2)) #1 Thu Jun 9 19:58:00 BST 2005 BIOS-provided physical RAM map: Xen: 0000000000000000 - 000000000927c000 (usable) 146MB LOWMEM

in dom0, how does one get and set the link information for a NIC? In a non-xen kernel, we could get this info by simply running: # ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes:

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. If a send a pppoe request

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?

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.

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,

I can not disable the auto-negotiation (eth1) on my centos 6.2 via ethtool or /etc/sysconfig/network-scripts/ifcfg-eth1 the eth1 is a private network on a cheap gigabit-switch (under controll from a serverhoster). sometime the ethernet-card lost the "speed" and "duplex" information and change it to "unknown". i can only fix this with a network-restart (or

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

Hi [1.] One line summary of the problem: rsync segfaulting and the kernel oops'ing while synchronizing two smbfs's [2.] Full description of the problem/report: I am implementing file synchronization between two Windows NT 4 machines through two smbfs mounts. Rsync runs for about half an hour; then the kernel gives an oops and rsync segfaults. Hereafter the smbfs file system is

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
