Using the onboard gigabit ethernet interface on an Asus M2N-CM DVI motherboard (nVidia chipset) with CentOS 5.2 the ethtool utility recognises that the NIC is capable of gigabit:
# ethtool eth0
Settings for eth0:
Supported ports: [ MII ]

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...
I am looking for a gigabit network card for my centos 5.4 server. I am looking for something known to work well with linux. I have been on the bestbuy site and I found a DLink (DGE-530T) card with support for linux from the vendor but after reading feedback from users with that card I am not so sure it is linux friendly. I am now thinking of buying online.

View 2 Replies View RelatedI 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.

I have a Netgear GA311 PCI Gigabit Adapter. Any chance it might work with CentOS? It is not one of the cards listed when I do "NEW" Ethernet Adapter from the System Network menu. Maybe there is compatible choice?
View 5 Replies View RelatedI've just set up a PC with CentOS 5.3 runing on near identical hardware to an existing 5.2 machine. Motherboard is Asus M2A-VM which I discover by chance generally works very well with CentOS. Ethernet is on board Nvidia.The older machine just did run gigabit speed without any intervention at all, rather to my surprise. The newer machine insists on running at 100 Mbit which is annoying as it is connected to a NAS through a gigabit dumb switch.
The obvious difference between the two is that ethtool on the older machine says that supported ports are TP, and so the port is TP. Whereas the newer machine says that supported ports are TP or MII and insists on running MII. I cannot change this with ethtool -s eth0 port tp. Perhaps not too surprisingly, mii-tool says that the supported speeds range up to 100 Mbit.

I have a newly installed CentOS 5.4 on Gigabyte G31M-ES2C, I had to change the motherboard since it has some problems. Unfortunately the new motherboard is a rev 2.x board, which has a different onboard NIC (old one is RTL 8102E, new one is AR8132), so now my ethernet connection doesn't work anymore (no eth0 device), I assume I need to install a new driver for the AR8132? If so, what's the steps to do so?lspci shows Ethernet controller as: Attansic Technology Corp. Atheros AR8132 / L1c Gigabit Ethernet Adapter (rev c0)
View 3 Replies View RelatedI 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.
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.
I'm running a wired gigabit card using the atl1c driver. It works fine, but I don't get gigabit, only 100 Mbps. I have a gigabit switch and other Ubuntu machines on my network are gigabit. Is there any way this could be a software/configuration issue, or is the only likely explanation that my wires are of sub-par quality somewhere?

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 recently upgraded a server's networking card to a Gigabit NIC, and got a hold of a Gigabit switch (Here's a link) in the hopes of increasing my network performance - however, I'm getting around 10 MB/s throughput now, which is exactly what I used to get with the old 10/100 switch & NIC. The new switch recognizes both computers as Gigabit (the other machine has always had a Gigabit NIC), and both computers say they're gigabit - I've found various sites around the interwebz recommending tweaking some TCP/IP buffer settings, which I have tried to no avail. I also saw that hard drive speed is usually the limiting factor. According to "hdmarp -t", the server HDD (definitely the slower of the two) is:
Code:
Timing buffered disk reads: 226 MB in 3.00 seconds = 75.26 MB/sec
So that's obviously not my issue. The cabling is CAT6 - I ran it myself, but if I'd mis-wired the end connections, wouldn't it just not work at all? I admit, I bought cheap NIC's (I'm not going for like 124.9 MB/s throughput here..), and I didn't expect them to be stellar, but I certainly expected the speeds to improve. I'm moving files from a server running Ubuntu 9.04 to a Windows machine - I've tried both my Samba shares on the server and an SFTP transfer: they both have about the same throughput.

View 7 Replies View RelatedWe have an old Zonet 10/100 switch in our home network that locks up whenever there's a power glitch longer than about a microsecond. (OK. It's not that bad but if the lights flicker, I usually end up going down to the basement to see if the switch is hung.) None of the computers or peripherals are affected by the glitches, BTW. Power-cycle the switch and everything starts working again. After putting up with this for months I finally picked up a Netgear 8-port 10/100/1000 switch to replace the Zonet. Unfortunately, when the Netgear switch is in the network, everything slows to a crawl before completely freezing up. Pinging other systems barely worksname would not work.Pinging another system by its IP address worked a little but packet losses of 70%-80% were the best I saw. At first. Then it gets to where the loss is 100%.
All systems were rebooted after the Netgear switch was inserted into the network. The systems that were capable of gigabit connections autosensed the new switch and set their port speed accordingly. And that's about all that works when the Netgear switch is present. (The Zonet is back in the network now.)One thing I have not tried is forcing the port speed on the gigabit-capable systems to 100Mb and re-inserting the Netgear switch into the network to see if the problem if due to running some of the ports at 1000Mb.The systems on the network are running various versions of Linux (with different kernel versions, of course). Most are due for upgrades to get them current but I was planning on hitting the systems that had gigabit-capable ethernet interfaces thinking that a.) 100Mb speeds have been around forever and no problems have been seen when everything was running at 100Mb in the past and b.) the gigabit support for the older kernels should be better (one system only supports an MTA of 1500 max at 1000Mb).
I have a following configuration: 4 PCs (say, A, B, C and D), running Ubuntu or Debian, interconnected using a gigabit switch, which is connected to the Internet. Two machines (say, A and B) also have a direct private connection between them (provided by another pair of NICs).
Now, when I test the connection performance with iperf, the results vary. The private connection between A and B performs well - about 930Mbps using iperf's UDP test. Between C and D it is about 800Mbps which I find tolerable. Packet loss when running these tests is negligible.
However, when I run iperf between any of {A,B} and {C,D}, the performance significantly drops as there is a huge number of lost packets.
For example, here is the result of testing between A and C:
Why is there such a large number of packets which are generated, but lost somewhere?
A<->B private link works fine, so system level parameters on both A and B are correct. Furthermore, C<->D works ok, so I guess I shouldn't blame the switch.
Is there a per-NIC configuration that I should check or it smells like a hw problem? Problematic NICs on both A and B are of the same type - Allied Telesyn AT2916T.
