Networking :: Red Hat Not Recognizing/assigning Onboard Gigabit Ports Correctly

Jan 18, 2011

I have two onboard gigabit Ethernet ports and 3 10Gb add-in fiber ports. When everything is cabled but nothing is IP'ed yet, I do an ifconfig -a and the two gigabit ports are showing as "__tmp2143330114" and "__tmp1076785124", eth0, eth1 and eth3 show as the 10Gb addin cards. On other (identical) servers, eth0 and eth1 are always the gigabit ports and eth2, 3, and 4 are the 10Gb ports. Anyone know what is going on?How can I make sure that Red Hat detects and assigns these ports correctly on boot, or at least can I reassign what ports are designated eth0-eth4?

OpenSUSE Install :: Suse 10.3 Assigning Wrong Drivers To Ethernet Ports (e1000, E1000e)?

Aug 23, 2010

I have loaded Suse 10.3 on a system that has 4 Ethernet ports, all Intel chipsets. 2 ports have the 82571 chipset, 1 port has the 82573 chipset and the last one has the 82567. The 82567 chipset can use the e1000 driver and the 8257x chipsets require the e1000e driver. We are only actually using the 82571 ports.

When the system is booted, the 82567 seems to get bound to the e1000 driver and the 82573 gets bound to the e1000e driver. Doing an "lsmod" I see both drivers loaded. It appears the 82571 drivers are getting bound to the e1000 driver which is a major problem. They work for a while but eventually they lock up with enormous error counts according to "ifconfig". How I know the e1000 driver is bound to the 82571 ports is that when I remove it(modprobe -r e1000) and then try to use one of them, I get a "network unreachable". When e1000 is loaded these ports seem to work fine. I tried modding the file in /etc/sysconfig/hardware that corresponds to the PCI address of these ports(i.e., hwcfg-bus-pci-0000:08:00.0) to force the module to e1000e, but no luck there either.

Ubuntu :: Onboard Nic Plug Broken Pci Nic Inserted Need 2 Remove Onboard

Sep 8, 2010

I just built a computer and the onboard nic pluggin is loose and won't register or connect right... so I had to put another nic card in pci to connect to wired network for internet. Problem now is its delaying something fierce... i'm thinking if i can manage to uninstall or disable the onboard nic maybe things would work better... problem is i wouldn't know how to do it... I know hardware is connected via a document somewhere in the file system... if I were to delete the file would that disable the nic or would it just reinstall itself on the next boot?

Networking :: Assigning Process To Use Specific Nic

Apr 19, 2010

I want to be able to tell processes/programs somehow to use a specific nic. I have a laptop (used as dekstop) and want to make pidgin use my wireless. I have a gigabit wired connection and a wireless connection. I want to force pidgin to use the wireless connection. But more specifically, I just want to block pidgin from using eth0... how to go about that? I can't find anything that will block applications... I could block outside servers from communicating with eth0, but I don't want to do that.

Networking :: Assigning Eth0 Value To Device

Dec 14, 2010

I have to do a project on network security.For that i have to capture the packets from the device. I installed libpcap tool in ubuntu. If I give ifconfig -a it lists out eth0, wlan0, lo. I am able to connect to the internet via eth0. But when I give

#include <stdio.h>
#include <pcap.h>
int main()
{
char *dev, errbuf[PCAP_ERRBUF_SIZE];

[Code]...

It says device is null. I'm not able to run sniffex.c program also. All I want to do is to capture the live network level packets and analyse them.

Networking :: Assigning Eth0 To PCMCIA Nic?

Apr 26, 2010

Just completed installing Xubuntu 9.04 to my old Dell Latitude CPi and it seems to be working quite well. However I need to assign interface eth0 to my pcmcia network card (as opposed to eth1 or eth2). I have two cards to try out. One of them comes up as eth1 and the other as eth2. There is no eth0 listed when I run ifconfig -a. There is no built-in network cards on the laptop, so I don't know why it won't assign eth0 to either of the cards.

how to assign eth0 to either of the two PCMCIA network cards.

Ubuntu Networking :: Assigning Host Names On LAN?

May 29, 2011

when I'm in my campus I saw things like this from tcpdump:

client-64-15.department.univ.edu
client-x-y.department.univ.edu
gw.nettokurabu.univ.edu

and my laptop got a name like that too (x and y being last 2 segments of the IP)out of curiosity, how to assign names like that to each IP? well, the names are not in dns records (can't resolve them to IPs)... when I set up (illegally) my on subnet with a routing software the addresses I used also already have their name without me configuring it before...

Networking :: DHCP Script - Assigning Multiple IP Addresses By Mac?

Sep 6, 2010

Ive been trying to give certain clients an IP adres by mac adress. For this I use the folowing code:

host apex {
hardware ethernet 00:00:00:00:00:00;
fixed-address 192.168.250.100;
}

This works perfectly, however when I try to add a second client this way it doesnt. I tried to add the above code multiple times as a whole (2 times the above code) but that doesnt work. I also tried to just add more lines under host apex but this also doesnt work.

So my question is: How do I add more of this mac related IP adress assignments in the dhcp.conf?

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?

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...

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 :: 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.

Ubuntu Networking :: Gigabit Card Only Works On 100 MBit

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.

Networking :: Gigabit Switch Causing Network To Freeze?

Dec 30, 2010

We 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).

Networking :: Huge Packet Loss On A Gigabit Link ?

Dec 28, 2010

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.
