View 1 Replies View RelatedI have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
I am using fedora core 2. I used the oldest version of fedora just because im running only 1 system, my specification is: HP compaq PC,pentuim4, 512mb memory, 40gig hdd, Intel board. I have two units same spec..windows xp and the other one is fedora 2. The windows xp normally detect the lan card, but when I try to fedora2, I try to active it and seems no lan card detecting,. How to detect broadcom nextreme gigabit ethernet to my fedora 2 OS???

I just kickstarted this box - I used eth0 and had no issues. After booting - eth0 is not available/present. This was not an issue in 5.2. This is a dell 4600 - both the 100mb intel and gig broadcom are onboard. I am about to try a different kernel. This is not a show stopper - it's plugged into 100m switch and I can just use eth1 - but I am curious as to what is different and why this no longer works.

Currently I'm running Ubuntu 10.10, Kernel 2.5.35-29-generic. I have a Broadcom 4318 for my WLAN and a Broadcom 4401-B0 for my ethernet. I followed the tutorial and I managed to get packet injection working on my WLAN; however, my ethernet connection isn't working. I tried sudo modeprobe b44, but I get the following message:
FATAL: Error inserting b44 (/lib/modules/2.6.35-29-generic/kernel/drivers/net/b44.ko): Invalid argument
My laptop only has a 100Mbit ethernet port, so I bought two external USB gigabit ethernet dongles in the hope of getting faster ethernet speeds. I have never had trouble with Linux supporting ethernet before, but neither of these devices are working. One is an ASIX AX88179 (by TrendNet) and the other is a Realtek RT8153 (by Anker). When I plug these devices in, I get network devices called enx00e04ca82300 or enxd8eb97b61e4d (instead of eth0/eth1 as I would expect).
I can manually set an IP address with "ifconfig enx00e04ca82300 x.x.x.x up" and manually add a route and my network connection works at gigabit speeds. However, the long enx... network device name does not appear to be valid in some sense: tools like dhclient or iptraf or network-manager fail with messages like "no such device" (well, network-manager just hangs). I don't know if it's because the name is so long or because they are not fully registered inside the kernel.
I have vmware workstation installed, and it does some strange things with network devices (setting up bridges for everything). I have disabled its services and see the same behaviour. This looks like a kernel bug to me but it's possible it is a vmware issue. vmware works fine with my wireless and 100Mbit ethernet (eth0 and wlan0).
Realtek device
Some dmesg for the Realtek device:

I have not investigated the ASIX device as much. However, my original 100Mbit ethernet has an ASIX chipset (AX88772) and that works perfectly. I have not observed the ASIX device crashing yet so I am using that for now (haven't used it for long yet though). But as before the device name appears to be invalid and I cannot run tools like dhclient. why two gigabit adapters with completely different chipsets would show up with long device names and support low-level stuff like ARP, ping, and static IPs, but fail with dhclient & network-manager? And the Realtek device seems to like crashing too.
This is my first post! I am a brand new Linux fan and am determined to understand how this system works! I am running Fedora 11. My wired NIC works just fine. I am having problems with wireless. I ran lspci -v to find my driver details, found it online and got it working so it would show up in the network configuration. I am having problems getting it to work from there. I am used to getting windows to install the driver and then being able to search for wireless networks. When I try to activate it i get:

I have spent them with Fedora and liked it a lot. Today I decided to install CentOS as this looks like something I would like to be using in the future. However a problem I could not solve came right at me after the first boot.
I have one eth0 device which is onboard lan and that was correctly recognised and activated. The second device is F5D5055 Belking USB Gigabit ethernet adapter. There was no problem with it whatsoever under Fedora. According to all the info it should be automatically recognised on kernel 2.6.14 and later. However when I plug it into the USB port, I can see its correct name in the device manager but it is not recognised as a network device. I have configured my Fedora as a firewall/router for my lan and definitely want to use that interface.
Hopefully without needing to do anything in the realm of compiling kernel, cause that is where my half a day long attempt to fix the problem left me.
Just did a clean install on a Dell Latitude E6400 of Slackware 13.1 and, for the most part, all is working great. Got wicd installed and wireless came right up, nvidia drivers installed and video is fantastic, but for some reason my wired connection isn't happening. The device is detected, but I can't get an IP.

Actually, the title I was looking for was Belkin Gigabit Ethernet ExpressCard not seen on Dell Precision M6500 with CentOS 5.5 _when system boots with no link on this card_. When I boot this system with a cable connected to the Ethernet port, the card shows up (dmesg, lspci 0e:00.0 and ifconfig). When I boot it with nothing connected, it's like it doesn't exist. I know I could make it work with a loopback plugged in at all times, but am looking for a more graceful solution. Here are messages logs from when it's recognized

Update: Should have been a little clearer - this card has the Marvell Yukon chipset. I'm trying to identify the part number without ripping out the casing.
We have a Linux box which acts a a file server. Currently, files and directories are exported using NFS.At the moment, we are a bit concern on its data transfer performance. FYI, we are using a embedded Gigabit Ethernet port on the file server. We ran a few simple write tests between NFS client (also utilizes GigE port) and the NFS server. In these tests, both NFS server and client are both connected directly to each other with a Cat5E cable. Unfortunately, the write/transfer speed results are not as per our expectation. It scores roughly about 11-12MByte/s, where as theoretically Gigabit Ethernet transfer rate is able to reach up to approximately 120MByte/s.I wouldn't expect to reach the theoretical max transfer rate (it would be great if we can , but I would appreciate if you guys can share with us in terms of the following :
1) What's the practical max data transfer rate which you guys managed to observe in a normal Gigabit based connection? What about jumbo frames configuration?
2) Is there any additional tuning/configuration we need to do within the OS to reach those practical max data transfer rate figure?
3) Does PCI-e / system bus plays a role in achieving this speed? For example, we are using the embedded GigE port and we heard some people says embedded ports are actually sharing the system bus and resources with other devices, which might adds into performance issue. Correct me if I'm wrong.
4) Does converting to Cat6 cabling will guarantee an increase in the data transfer performance?
5) In the future (once we are clear on how much single GigE transfer rate we can go) , we are looking into doing bonding since that the NFS server's shared directory/volume read-write speed is way much higher (i.e 400-600MByte/s). Will bonding allow us to achieve higher NFS read/write speed? What are the bonding modes best used for this purposes? Appreciate if anybody who has experience in doing bonding for NFS can share their experience.
I installed Fedora 14 on my new PC but I don't have network connection. In fact, I hit the command "lspci" and the prompt return :
Code:
Ethernet Controller : Intel Corporation 82579V Gigabit Network Connection
So, I created a ifcfg-eth0 file on /etc/sysconfig/network-script because it doesn't exist :
Code:
DEVICE=eth0
TYPE=Ethernet
BOOTPROTO=dhcp
ONBOOT=yes
Then, I restart network service, but eth0 is down, no device found for the connection eth0.
With what command i can check whether my Ethernet card supports gigabit speed Ethernet or not?
View 1 Replies View RelatedI have 2 10.04 machines connected through a switch, both with gigabit on board ethernet. Both machines show 1000 Mb/s connections.When I transfer large files (gig plus up to multi-gig) the maximum I get according to ftp 11472 kB/s.I did rough computer school math in my head and that seems low but I'll admit I know very little about network transfer rates.My question is what transfer rates should I expect to get between the 2?
View 9 Replies View RelatedCost effective (the people want cheap) solution to increase server storage space with as little impact on throughput (what I want) as possible. I have a server that sends instructions to 20 clients to perform certain tasks. The clients send gigs of data back to the server for storage.
BACKGROUND INFORMATION
Network: Gigabit Ethernet
Clients: (20) HP, Solaris, Linux
Linux Server: Dell R805 PowerEdge (QUAD Core Athlons 16 gigs of ram, 4 gigabit ports.
Selected directories are mounted (NFS) by clients. One directory to be mounted by the clients contains executable files. Mount commands are sent from the server (rsh) to the clients. Yes I know (ssh) but this is how the software was originally written so let's go with it.
The clients then receive commands to execute the binaries contained within the mounted directory. The binaries basically create an image of the clients filesystem including special applications. The client then sends the files and directories to the server which stores this �image�. This process can be reversed to restore a client to the initial baseline image.
In a nut shell, 20 clients are sending gigs of data to the server for storage. I need to attach a NAS (gigabit) to extend the storage capability of the server. The server would mount (NFS) to the hard drives on the NAS. The NAS, configured as a �direct attached storage� device (DAS), means the storage device is connected directly to the server and not the network (which makes it a DAS). This would provide direct storage expansion for the server. However, this configuration cannot be a bottleneck that significantly hinders performance.
Clients <---data---->Server<----storage---->DAS/NAS
1) Will a low end NAS (gigabit port) work? (NetGear 1TB ReadyNAS Duo, RND2110-100NAS) or something with a higher rated throughput (QNAP TS-239 Pro II)
2) Low end won't work, go with �?
3) Does the processor on the NAS play any role that would determine the performance of this configuration given that the server would mount directly to a directory on this device (DAS/NAS)?
I have an ASUS P5Q PRO motherboard with an integrated Atheros AR8121/AR8113 PCI-E Gigabit Ethernet Adapter.I installed Ubuntu 10.04 "Lucid" 64bit Kernel version 2.6.32.21 I have read that the driver isn't in the kernel, but there's a strange thing :
First if I try to run lspci from command line it doesn't reports Atheros Ethernet Controller.
Second If I try to run lshw -C network from command line it doesn't reports Atheros Ethernet Controller.
Third if I run ifconfig it only returns my loopback address.
Can I suppose that my Ethernet Intel Gigabit Controller is broken or that Atheros driver is missing?

If you haven't added any repositories to your system you will need to do so before using zypper to install the required packages below. (instruction on how to do this under heading add repositories below)
Short Fix (This fix works if you haven't already installed b43-fwcutter firmware, and the b43, ssb kernel drivers are not load.)
zypper remove b43-fwcutter
zypper in broadcom-wl broadcom-wl-kmp-desktop
modprobe wl
reboot (and wifi worked after I activated it using FN F3 to turn it on)
Long fix if required

List of Repo's I have added
1. main (contrib)
2. Mozilla
3. Packman
4. Wine
5. Kde Extra's
Packman and Main (contrib) are the most likely sources of the required files.
Once you have added these you should be good to install the required files.
One final note, I had to use an external usb wifi card to connect to the internet to add the repo's and download the required software. Lan card support coming in 2.6.38 kernel (it is suppose to add a driver for our lan card).

Since this is my lab box I thought its time to give Fedora 12 a try.
I did an DVD upgrade from 11 to 12 and rebooted. The Broadcom came up fine this time. I did a yum upgrade to finish from whatever was not on the DVD and rebooted. This time no 'b43' network card was recognized. I still had my third part driver files so I:
b43-fwcutter -w /lib/firmware/ ./broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o
and a 'modprobe b43' and I had my card back.
I am sorry for dragging this out this far, but now every time the Fedora 12 box reboots I have to type in modprobe b43 to get my card to work. I did not have to do this for neither Fedora 10 nor 11.
I put a line in /etc/modprobe.conf - 'alias wlan0 b43' but I still don't get my wireless card until I type modprobe b43.

I am running CentOS 5.3.The NIC on my motherboard does not support gigabit, so I bought a gigabit network card. I installed the network card and configured it via system-config-network. Everything seems to work fine as long as I keep a cable plugged into the original NIC. The original NIC works just fine if it is the only one with a network connection, but as soon as I uplug the original NIC I can no longer ping nor connect to the server via the gigabit NIC.
The original NIC is eth0, the new NIC is eth1. Is there something I need to do to tell the system that eth0 is not required or something? I've never encountered an issue like this before...
