network collapse
based on what your saying.. im not thinking this is samba related.
I guess check your switches and find the "fault" autosense for your nics..
You can use thisone to disable autosence
ethtool -s ethX autoneg off
en set correct nic speed.
ethtool -s ethX speed XXXX
BUT ! check your switches first.

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 :

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,

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.

strange ethtool output in xen environment
I want to check the speed like features of my Ethernet in dom0 and domUs. But in virtualized environment it gives strange output why is that so? how to check it otherwise?

Attempting to checksum a non-TCP/UDP packet errors rolling across screen
Hello,
Just did a fresh install of xen-4.0 and using the 2.6.31.13 dom0 kernel.
I have 6 linux debian guests running, and on my host console i am
getting these errors rolling pretty constantly.
"Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet"
I tried doing the ethtool -K eth0 tx off and same thing on peth0,
using bridged mode for network config.
Any tips?

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

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?

xen 3.1/ RHEL5 vs. ethtool
I have the xensource 3.1.0 x86_64 tarball installed over
a RHEL5 clone distribution. The "ethtool" utility only
returns the following information:

Settings for eth0:
Link detected: yes

Since I have no vanilla-installed rhel5 machines with which to compare,
I am not sure if I am dealing with a bug in the ethtool

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.

XCP 1.0 beta Realtek 8168 nic not working
I''m trying to build out a test cloud using XCP 1.0.0 beta with 3 machines of
18 cores total (Phenom II 1090s). I''ve built three machines, installed XCP
1.0.0 beta on them and they all three
have the same problem - the Realtek network cards don''t work. The following

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

hosts fail to negotiate 1000Mbps speed
I am trying to connect two workstations (CentOS 3&4) directly using a
straight through cat 5e cable with a crossover adapter on one of the
ends. Both hosts have gigabit-capable ethernet card. According to
lspci host 1 has:

Thanks for the hints. Selinux is disabled, there is no outgoing firewall

Network issue - Windows works but CentOS does not
I am having an extremely strange issue with a BL460c1 (G1) blade on a
c7000 enclosure. I could not for the life of me get the machine to ping
the gateway or any other blade on the same enclosure (yes, the subnet
mask was correct & quadruple-checked); although pinging to the local IP
works. I was almost convinced that it was a network or hardware issue;

Maybe a bug of xen
Hi!
Maybe, I found a bug of xen.
My system:
- domain0 - gentoo - xen-devel-3.0, kernel 2.6.12.5-r1
- domain1 - debian - kernel 2.6.12.5-r1 (2 interface: vif1.1 = eth0
(0.0.0.0), vif1.2 = eth1 (10.0.1.1 + gw 10.0.1.2))
Bridge:
xen-br0 (config as 10.0.1.2) include (vif1.2, vif0.0)
xen-br1 (config as 0.0.0.0) include (vif1.1, peth0)
On server domain1 I use a pppoe server.
