We've just moved one a new server from our sever room, where I built it, to the datacenter. We want to force autoneg off, and tell it gigabit and full duplex. Using ethtool, I get no errors setting the speed or duplex. HOWEVER, autoneg on works... and autoneg off utterly refuses to work, and gives: ethtool -s eth0 autoneg off Cannot set new settings: Invalid argument not setting autoneg

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

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 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

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.

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

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? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -

Anyone know off the top of their head the "right" way to hard set a link automatically to 100Mbps Full Duplex, etc using the ifup or ifcfg files? Don't see options in the scripts that might cover this, but maybe there's a more elegant way to do it than to do something in rc.local or hack up the ifup files myself... Ray

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

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

Hi, recently we upgraded a central RHEL 5 fileserver to the latest RH EL 5.1 rpms, including samba. (samba-3.0.23c-2.el5.2 update to samba-3.0.25b-1.el5_1.4) Now some users have the problem, that opening a word or excel file saved on a samba share takes up to 30 seconds. Today I could verify this on the users desktop XP PC. This problem occures only from time to time, so it may be also a

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 : ???????

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

Hi I installed xen by following this link: http://www.howtoforge.com/virtualization-with-xen-on-debian-lenny-amd64 Dom0(debian) has two IP :174.x.x.79 , 67.x.x.32 gateway is 174.x.x.65 DomU(win2003) IP is :67.x.x.38 The problem is : 1.weird network issue in win2003(can not access the internet in win2003): A:weird ping time for 127.0.0.1 B:weird ping time for its own ip 67.x.x.38 C:timeout

We are in the process of an Asterisk call center deployment using IAX2 G711 ulaw softphones. Outbound sound quality is terrible. This week we rebuilt the entire LAN with Cisco 2950-EI switches and have employed QoS on the switches and router. Still sounds terrible. What we are now finding is that the network card in the PC may be the key to the problem. A Dell Optiplex P4 2.4GHz 512MB

based on what your saying.. im not thinking this is samba related. I guess check your switches and find the "fault" autosense for your nics.. You can use thisone to disable autosence ethtool -s ethX autoneg off en set correct nic speed. ethtool -s ethX speed XXXX BUT ! check your switches first. greetz, Louis >-----Oorspronkelijk bericht----- >Van: sambait3 at

Hi, At first glance, this appears to be a fairly simple routing issue, but I''ve checked the configuration and am a bit mystified. I am using Xen 3.0.2 here in bridged networking mode. Firstly - four servers. Dom0 - 75.126.2.202 (RHEL4) domU (CentOS) - 75.126.3.248 -> 75.126.3.251 Dom0, .248, & .249 can all talk to each other okay (& the outside world) However, for some

Greetings. When I "pull" data from server A to server B, with nfs, server B reports a high load when viewed via uptime. The load is upwards of 6.x. Server A's load remains light. When I "push" the data, server A's and B's loads are relatively light. When I change the mount point from nfs to cifs, I don't see this problem. I also don't have this

I have a problem. I've purchased 2 different brand NAS devices that both use Samba in some form as their "sharing" mechanism. When I attach them to the LAN I get dreadful speed. To the tune of under 3.5GB per hour transfers. I've even done tests on the same subnet. Two Windows servers on that vlan can move files at great speeds. Map one of them to the NAS and it crawls. I recall

Hello, I have installed CentOS 5 onto a server this afternoon using NFS. The NFS 'server' has a 100Mb/full-duplex interface, the server I installed CentOS on to has 4 x 100Mb interfaces. However, the installation was painfully slow to start with, and by using ctrl-alt-f2/f4/f5 I could see that contact with the NFS server was intermitently failing. Soon after some of the packages had
