I recently did a clean install of Ubuntu 10.04 on my machine. It previously had windows 7 on it and everything worked flawlessly. Now the gigabit LAN connection only connects at 10Mb/s under Ubuntu. I installed a virtual machine with windows 7 and there it connects at 1Gb/s.

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?

I have tried using ethtool to force the speed to gigabit but it doesn't seem to have any effect. I'm using Ubuntu 11.04. Does anyone know a way other than ethtool to set the network speed?

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.

I have bought two Asus NX1101 gigabit cards for my kubuntu box and ubuntu server box. The cards are automatically detected as eth1. However the speed is set to 100mbit instead of 1gbit.

I noticed that both lshw and ethtool claim that the card does not support 1000mbit. So changing the speed manually with ethtool doesn't work. In windows XP the card works as it should.
I'm building a new system with a Gigabyte E7AUM-DS2H micro-ATX motherboard. The onboard lan is a gigabit RTL 8211CL chip. The led on the port is orange when it is in gigabit mode and green if it's 100Mbps.When I power the machine on, the led is orange. After ubuntu loads, it goes to green. Oh, and it -is- connected to a gigabit switch. I don't know where in ubuntu to set it to stay in gigabit.Here's part of lspci:

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...
Finally updates are broken - I've been able to use my upgraded F12 system for some time, faithfully keeping up with f10, then f11. Just yesterday it finally broke:
Test Transaction Errors: installing package kernel-2.6.31.12-174.2.22.fc12.i686 needs 10MB on the /boot filesystem
It would appear that the most recent kernel update has broken the 10MB barrier initially set by the version I first installed (for the boot partition). Needless to say, I have quite an investment in this machine, and of course no time to back it all up and do a fresh F12 install. I am hoping someone out there can give me a bulletproof way to steal some space and expand the boot partition...

I just bought a new router with gigabit ethernet.
However, my HTPC running Ubuntu 10.04 (32 bit) with a Zotac ION mainboard can't obtain gigabit speed. I have tested the cables by connecting my laptop and it gets gigabit speed. I also have a desktop computer that obtains gigabit speed in my network, this one with another Nvidia chipset and Linux Mint 11.
I have tried to boot the HTPC with Linux Mint 11 LiveCD, but it fails to get gigabit as well. I have also tried
Code:
sudo ethtool -s eth0 speed 1000
but it does not succeed in chaingin the speed.
Is there anything I can do to get gigabit speed? I have all my files on the HTPC, so network speed is important!

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 am looking for a PCI Ethernet adapter which supports jumbo frames. The card I have now - Trendnet TEG_PCITXR - says it supports jumbo frames but it turns out the MTU is 7200 bytes. Yeah this is more than 1500, but it seems like a bit of a scam to me. Since it is nearly impossible to find these specs on product info pages, I was hoping someone could recommend a network card that is proven to support 9000 (or greater) MTU. Some more info, I am running Ubuntu 9.04, kernel 2.6.28-19

View 2 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).
how to install intel 82573E gigabit on centos 5
View 2 Replies View RelatedI 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.
