Ubuntu Networking :: Can't Obtain Gigabit Speed With Nvidia MCP79

Jul 27, 2011

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!

Here's some info that might be useful:

Code:
christian@htpc:~$ dmesg | grep eth
[ 1.243230] forcedeth: Reverse Engineered nForce ethernet driver. Version 0.64.
[ 1.244597] forcedeth 0000:00:0a.0: PCI INT A -> Link[LMAC] -> GSI 21 (level, low) -> IRQ 21

Ubuntu Networking :: No Speed Improvement With Gigabit NIC / Switch?

Jan 13, 2010

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.

Debian Configuration :: Slow Transfer Speeds On SAMBA Share But Gigabit Speed On SCP

Feb 12, 2016

I'm having a strange problem with data transfers between systems. I have a file server + my desktop. Both are running Debian 8.3. I have a samba share running on the file server and I mount the shares on my desktop on boot via /etc/fstab

When I copy a file using the nautilus from my home folder (on my HDD) on my desktop to the mounted network location, my transfers start out at gigabit speeds 80MB/s-90MB/s for a couple seconds and then drop down to about 8MB/s

But when I terminate the transfer and then use scp to transfer the same file, I get consistent gigabit speed throughout the transfer. I am not sure what is going on.

Ubuntu Networking :: Not Getting Gigabit Connection

Aug 24, 2010

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?

Ubuntu Networking :: Automatically Obtain A New IP?

Jan 26, 2010

I have an Ubuntu server running behind a router and I generally manage it from a remote location. I ran into a problem today when I changed the subdomain that the router is on and in turn changed all of the ip addresses for everything on the local network. After restarting the router, I can no longer access the Ubuntu server.

I made sure that I changed the port forwarding settings to reflect the changes in ip addresses. Also the router does not even show the Ubuntu server as having an ip address issued to it. So from that I guess that the server never requested for a new ip after the router restarted. I think I've had this problem before and I ended up restarting the entire server manually. I know that if I restart it, everything should be back to normal. That's what I'll have to end up doing, but I wanted to avoid having this problem in the future, so I was wondering if there is any way to set up the server so that it requests for a new ip address automatically.

Ubuntu Multimedia :: NVidia GTS250 Running Hot - Can't Change Fan Speed

Jun 28, 2010

I'm running a XFX Nvidia GTS 250 512MB card. I have installed Ubuntu 10.04 and so far I'm loving it - apart from one small issue. Using 195.36.24 drivers, I cannot control the fan speed - it keeps running the card pretty hot - hitting 75 deg. C when one OpenGL game is running. The fan barely goes over 60% speed - I'd rather have it run at 80% constantly to keep the temps under control.

There are drivers on nvidia website which "seem" to be a lot newer : 256.35 (using 64bit Linux) - are those "direct replacement" for the 195.36 which Ubuntu installs by default?

I have a well ventilated case (1x120mm pulling air, 1x120mm pushing out, neat cabling, etc). I have found nvclock but no joy - even with -force it doesn't want to change fan speed.

Ubuntu Networking :: Gigabit Card Only Works On 100 MBit

Apr 14, 2010

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.

ifconfig eth1 .....

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.

CentOS 5 Networking :: Trying To Upgrade To Gigabit

Feb 12, 2010

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...

Ubuntu Networking :: Cannot Obtain DHCP Lease ?

Feb 7, 2010

I have a home WiFi network that has been working fine for ages, which currently supports two Windows-based laptops and a WM5 smartphone. They all connect to the WiFi router (Linksys WRT54G) which in turn connects to the ADSL modem (Huawei MT882). The router is configured with a WEP key, the SSID is not being broadcast, and all MAC addresses must be whitelisted. I try to follow good wireless network security practice. I also have NAT running between the router and the modem.

Everything is working fine for the Windows clients, and now I am trying to add my Linux box to the mix. I am setting up an older HP Pavilion 510a desktop with Ubuntu v8.04LTS, using a Realtek RTL8185 WLAN card. The machine has an onboard RTL8139 LAN adaptor also, which works fine when I plug it in directly to an ethernet port on the wireless router. The WLAN, however, does not seem to be getting a DHCP packet, and keeps on autoconfiguring with a 169.254.x.x address. When I try giving it a static IP address it doesn't connect either.

As you can see from the screenshots below, the WLAN is working fine. I have it installed using the ndiswrapper and Windows drivers. I've been through the Comprehensive ndiswrapper troubleshooting guide but that did not resolve my problem.

I configured the network myself, and it works perfectly for my Windows machines. It is just my lack of experience with Linux which is preventing me from getting the wireless to work under Linux. I can get a HDCP packet in Linux when I am connected to the LAN using the RTL8139 adaptor, but not on the WLAN using the RTL8185 adaptor.

Debian Hardware :: Nvidia GPU Overheating And The Fan Run At Very High Speed

Aug 15, 2015

Yesterday I've installed Debian 8.1.0 on my desktop pc. I'm using Nvidia GT 730. After booting, the GPU fan runs at very high speed and really gets overheated. I didn't install any drivers etc.

Is there a solution for this or do i have to switch to Intel/ATI to use Linux? I said Linux, because every distros i've installed makes Nvidia chipset overheated and the fan runs at max. speed.

I'm terrified about making the GPU burnt.

Ubuntu Networking :: Expected Transfer Rate For Gigabit Ethernet

Sep 26, 2010

I 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?

Ubuntu Networking :: Atheros Gigabit Controller Stuck At 100 Mbps?

Apr 18, 2011

I'm using Ubuntu Server 10.10 64 bit and am trying to get my Atheros AR81xx gigabit ethernet controller to use 1 gbps.I have 2 ethernet controllers, one's a linksys 100 mbps (which is connected to the router which goes to the internet) and the other is the Atheros gigabit controller that is connected to a Windows desktop that has an NVIDIA gigabit ethernet controller (for faster file transfers with a gigabit connection) I've ruled out that the problem is with the desktop as I plugged the windows PC into my macbook (which has a gigabit controller), and both the macbook and desktop report a gigabit connection.

I plug the windows desktop into the server and I only get 100 mbps. I am using a Cat 6 patch cable. I've tried several methods with ethtool to force it into 1 gbps mode, but none work. I've tried using a different cable. no change. I've tried making windows force a 1 gbps connection, didn't have the option to in the driver configuration. Only 10/100 configs. the commands I've tried in ethtool

Code:

ethtool -s eth0 speed 1000

Reports no error, but no effect. I've tried forcing off auto negotiation (I had a hunch it was causing the problem)

Code:

ethtool -s eth0 speed 1000 duplex full autoneg off

I get this

Code:

Cannot set new settings: Invalid argument
not setting speed
not setting duplex
not setting autoneg

I tried each setting individually, and autoneg won't set, the others will (but not do anything)

Networking :: Transfer Rate For Gigabit Ethernet

Apr 1, 2010

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.

Ubuntu Networking :: Wireless Connection Cannot Obtain IP With DHCP

Feb 16, 2010

I have router and wireless card Linksys. Driver are installed correctly for wireless card.

Using WifiRadar I can see the access point is detected.

DHCP woks perfectly for wired lan.

However when I try to connect to the detected access point the ip addres is never retrieved and the connection never established.

I tried most of he basic instructions posted on ubuntu forums, but the problem doesn't seem to be with basic configuration: driver, essid, wep key, etc..

The problem seems to be with DHCP not able to retrieve an IP address from the DHCP server of the router. Of course the router works file with other laptops (windows based) that have wireless card.

I also tried the Network Connections setup part of ubuntu. That one shows the access point by its essid name in the list of wireless network, but when I try to connect it takes sometime and eventually asks for the wep key, which I provide and then it times out and keep asking it. The same wep key works for other pcs.
Can't figure it out. I am using ubuntu 9.10.

Some more details are the following:

1) Here the output from the log file: /var/log/wifi-radar.log

Of course it is set ... and dhcp client works for wired lan anyway.

2) diego@mysuperlaptop:/var/run$ sudo iwlist wlan0 scan [sudo] password for diego:

I tried everything I could think about in the UI windows setting (WifiRadar and Wireless Network Connections) a well in the config files from the shell. I just don't get what the deal is. I am pretty sure it is a DHCP issue but can't figure out what.
