I am having an extremely strange issue with a BL460c1 (G1) blade on a c7000 enclosure. I could not for the life of me get the machine to ping the gateway or any other blade on the same enclosure (yes, the subnet mask was correct & quadruple-checked); although pinging to the local IP works. I was almost convinced that it was a network or hardware issue; until I asked someone to try

Greetings, I recently installed CentOS 5 on Dell PE 1750 server. I have noticed that the speed and duplex settings are 100 Half Duplex. I tried to change the duplex settings to full, but no success. I got the error message "Cannot get current device settings: Operation not supported". Does anyone else experience this issue?. Below is the error message and some more details about my box.

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 come across some problem when using xen-4.1.1-rc1-pre from xen-4.1-testing tree and 2.6.32.36xen linux kernel from git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git. when I use ''xend restart'' , it hangs when kernel dmesg printing ''Bridge firewalling registered'' and the console show below messages: localhost# xend restart Nothing to flush.

File Server OS: CentOS 5.3 (x86_64) Kernel: CentOS Plus kernel (need XFS fs drivers) The file server has a Chelsio T310 10GBASE-CX4 RNIC (rev 3) PCI Express x8 MSI-X (eth0), driver and firmware is stock from the CentOS Plus kernel. Using ethtool I have verified driver association with the 3 NICs on the system (eth1 and eth2 are not connected to any switch) Driver for eth0 driver: cxgb3

How much of an impact can/does local network traffic have on call quality? Would opening large files on local servers affect call quality? We are running QoS on the router but that will only prioritize traffic in/out of the network.

I have no output in the logs, but /etc/init.d/network restart fixes the issue. I am rsync/scp (10GB) data from one 100MB Full duplex host to an ASUS M3A78-EM (RTL8111B/C). It locks up around the 1.5GB Tx mark. If I ethtool -s eth0 autoneg off speed 100 duplex full it does not happen again. Ideas? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -

I've got a Dell Precision Workstation 490 with 64-bit Centos 5, fully updated, with an on-board Broadcom 57xx gigabit Ethernet controller, updated BIOS, 1 GB switch, and /var/log/messages and dmesg both claim the link is 100 Mb, not 1 GB. I tried setting eth0 to mtu 9000 but got an error in going so. What do I need to do to have the card see 1 gb? Thanks. Scott

I can't explain why 700 msecs aren't enough to avoid timeouts in 100 Mbps networks, but my tests verify it, so I'm writing to the list to request that you increase the default timeo to at least 30, or to 600 which is the default for `mount -t nfs`. How to reproduce: 1) Cabling: server <=> 100 Mbps switch <=> client Alternatively, one can use a 1000 Mbps switch and

Two problems I hope to solve: 1. The switch being used has autoneg off and has port set to 100 full duplex. 2. Many times NIC fails to come up properly during PXE boot: r8169: eth0: link down ADDRCONF(NETDEV_UP): eth0: link is not ready I can't use ethtool to disable autoneg because the nic driver is built into a bzImage. The root fs is currently being mounted via nfs during pxeboot at

Hi folks on debian stable I've a default samba file sharing config. Everything works perfectly (almost...) - samba version 3.6.6 >From linux and windows clients (wired and wifi too) when I (i.e. listen musics) often (one time every 4/5 minutes) networks suddenly collapse (for less one second) and immediately goes up. So I've an interrupt of broadcast (this happens also if I use rsync

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 : ???????

Hi all, I have two HP DL145 G1 machines, running centos4 (2.6.9-22.0.2.ELsmp). Nics are recognized as: eth0: Tigon3 [partno(BCM95704) rev 2002 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:00:1a:19:f1:05 eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] Split[0] WireSpeed[1] TSOcap [1] eth1: Tigon3 [partno(BCM95704) rev 2002 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet

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

Okay Ive had a day of it today , and I thought I would share this little support event experienced today. A Client site of mine runs Samba 2.2.8a connecting to a series of Windows XP boxes via a Netgear Switch/Hub. Earlier in the week they reported that certain applications, most notorously Symantec ACT were performing at super slow speeds. A non site investigation showed that any file

From: Nikolay Aleksandrov <nikolay at cumulusnetworks.com> This patch allows the user to set and retrieve speed and duplex of the virtio_net device via ethtool. Having this functionality is very helpful for simulating different environments and also enables the virtio_net device to participate in operations where proper speed and duplex are required (e.g. currently bonding lacp mode

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:
