tg3 ethernet card drops connection under heavy load
We have an HP DL360 server with dual on-board Tigon3 ethernet cards.
We are using eth0, eth1 is unused at the moment. Sometimes when the
network interface is under heavy load, for example moving large file
transfers over rsync or NFS, the network interface stops working and
we lose all connection to the server. The only solution at this point
is to jump on the console and restart the network

Getting Wake on lan to work
My system is:
Intel CC820 motherboard (which supports PME# wake up for wake on LAN)
3com 3C905C which also supports wake on LAN via PME#
Linux 5.5
The motherboard BIOS is later than one that reports an issue with WOL
and this particular network card was fixed.
But when I turn off the PC (shutdown or poweroff commands or front
panel button), it cannot be restarted via WOL. The network light on

ethtool to view and set network parameters
in dom0, how does one get and set the link information for a NIC? In a
non-xen kernel, we could get this info by simply running:
# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes

RTL8111/8168B always 100mbps
Dear All,
I have an onboard Realtek RTL8111/8168B NIC. from lspci -vv :
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
It is detected, but why the speed is always 100Mbps, already change
cable but still no luck. I use ethtool and from the output it seems
that system know that this NIC support gigabit speed :

QoS General Question
How much of an impact can/does local network traffic have on call quality?
Would opening large files on local servers affect call quality? We are
running QoS on the router but that will only prioritize traffic in/out of
the network.

Samba running slow
Hello everyone:
Over the past few years I have been a happy samba user, running samba on
Redhat / FC platforms. Recently I upgraded hardware, and Samba hasn't been
performing well at all.. which makes me sad :-(
The new hardware is Asus P5B board with a dual-core intel processor. This
board has an onboard Realtek RTL8111/8168B gigabit ethernet controller,
which was a hassle to setup.

Access to shares too slow
Hi all,
we recently moved our offices to a bigger place. Therefore all our
servers and network electronic had to be turned off... :)
Well, I know it sounds odd but after the move Samba is much slower
serving the shares and users have to wait ages for the information to be
copied or moved across the network. In some cases, Windows desktops seem
to freeze until the data is retrieved from the

bonding & vlan - kernel 2.4.18 (RHL7.3)
Hi,
Hopefully this won''t be too off-topic (I''ve seen both bonding & vlan
mentioned on the list, but not really together).
I''ve tried to get bonding (2 x 100Mb EEPro, but will want to try on
1000BaseT) and vlans to work together, but without luck. I can get them
working fine (seemingly at least - I didn''t tried bursting on the
bonded port) individually.

Ethernet puzzle
So I just finished doing a fresh install of CentOS 6.3. The
machine has three ethernet ports in it: one on the motherboard (VIA
Rhine), and two add-on cards, an Intel Pro100 and an old SMC1255TX. When
CentOS comes up, this is what I see in the dmesg output:
# dmesg | grep eth
e100 0000:00:08.0: eth0: addr 0xf6043000, irq 16, MAC addr

gigE -> 100Mb problems
I've got a pair of identical CentOS 6.7 servers, with SuperMicro X8DTE-F
motherboards, these have 2 each Intel 82574L ethernet ports. The eth0
ports are plugged in with 10' runs of brand new cat 5e cable to a Cisco
Nexxus 9000 switch (provided by the data center).
These servers keep coming up at 100baseT rather than gigE. I've swapped
ports and cables with a different server,

Bonding Eth interfaces - unexpeceted results
CentOS 6.2.........
Why do the physical interfaces report (correctly) that they're negotiated at 1000Mb/s, but when I `cat /proc/net/bonding/bond0` I get 100Mbps for the member interfaces, and when I ` mii-tool bond0` I get 10Mbps for the bond?

Yeah, the entire "net-tools" package is deprecated. I tend to forget
which of the two (ethtool or mii-tool) is in that set.

8139 dropping packets
I have a CentOS 5.8 box that is dropping packets (just from ping).
The network is 8139 RTL-8139/8139C/8139C+ Rev 10
Adding the parameters "pci=noacpi acpi=off "
has helped but it still happens.
Is there something else that helps the network not drop packets?
Thanks,

Ubuntu 8.04 Hardy Heron bridged networking xen connectivity loss
Last problem I had involved changing one character in my configuration
scripts. Really easy once someone showed me what was wrong.
Well I think this issue is just the same. The moment I used apt to
install the Xen kernal and tools I lost internet connectivity. I have
been managing because I can restore connectivity be deleting the bridge

PPPoE client help
Please point me in the right direction....
My ISP is giving me an IPv6 prefix, but to get that I have to:
The current Speedstream ADSL router will be configured as a bridge. I
will have to set up a Linux (read Centos, I hope) router that will
connect ethernet to the Speedstream but run PPPoE to his network and get
both the IPv4 and IPv6 route delegations.
There is no easy way that I know of

NT Crashes when doing large network file Xfers (was Re: NT crashes during smbtar)
Ok.. Just for the record, I STAND CORRECTED! The problem does
appear to be NT.. The thing that irritated me was that nobody was
interested in giving any backup data! Everyone just wanted to blindly
admit that it must be NT. Ok.. Enuf bitching.. On to the better stuff...
Anyway, David Mansfield and I are trying to narrow down the machine
configurations where this happens.. Currently, we've
