Eth1 problem on CentOS-6.3
I am trying to transport a dd image between to hosts over a cross linked gigabit connection. Both hosts have an eth1 configured to a non routable ip addr on a shared network. No other devices exist on this link. When transferring via sftp I received a stall warning. Checking the logs I see this: dmesg | grep eth e1000e 0000:00:19.0: eth0: (PCI Express:2.5GT/s:Width x1) 00:1c:c0:f2:1f:bb

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 : ???????

RTL8111 Wiki Pages
Howdy, It appears that CentOS 5.2's support for the RTL8111B/C chip is incomplete. The wiki has some blanket statements regarding this support: http://wiki.centos.org/AdditionalResources/HardwareList/CentOS5/RealTek/r1000 http://wiki.centos.org/AdditionalResources/HardwareList/RealTekRTL8111b I could dive in an make the changes *I* think need to happen but I'd like to talk to people

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.

r8169-driver CentOS5.2
Hi all, Another FYI-mail (and just to verify that I'm not going insane here); I recently purchased an ASUS M3A78-EMH HDMI -board with a tri-core Phenom. This is a small uATX-board with all the garnish integrated motherboards are supposed to come with, and fairly well supported in CentOS 5 and other modern distros. When I installed it (~2 months ago) the NIC was not supported; Ethernet

Issues with r8169 gige on boot.
Hi all, I've recently upgraded a system from CentOS 4.4 to CentOS5, and now when the system boots, the r8169 ethernet card doesn't come up. After the boot sequence, if I type "ifup eth1 | ifup eth1.10 | ifup eth1.203" then the adapter starts up ok. It seems to be something with the boot sequence it loads the ethernet adapters a different way around (ie 4.4 eth0 is now

[XCP] - XCP -> HCL
I''m needing to put a network card on a test server XCP 1.0. I''m seeing the citrix hcl (http://hcl.xensource.com) and I''m a doubt. I base that on which version to look for a compatible card? If the kernel is the same as in 5.6.0 FP1, but if the version of XCP uses the hypervisor 3.4.2 neither appears on the list. ps: I had a RTL-8169 but stopped working with update 0.5

RealTek 8168B (Rev 02) Issue
The 8168B (02) NIC works well except that it does not go into promiscuous mode despite advertising itself in that mode after being so directed with ifconfig. Unfortunately, the little box is destined to be an IDS monitor, so that function is essential. The board is an Intel Atom 330 run as x86_64, the nic is internal. We tried three drivers: the one in the 2.6.18-128.1.10.el5 kernel yields

Saurabh Nanda <saurabhnanda at gmail.com> writes: > 1) Why is the log saying `SMB2` everywhere? Shouldn't it be saying > `SMB3`? "SMB3" is mostly marketing, it inherits almost everything from SMB2 hence why it's often handled by SMB2 code. You will see this in Samba, Wireshark, Linux, and even Microsoft specification "MS-SMB2" which actually covers both

Odd transfer speed issue
Hi all, I'm seeing slow transfers to/from my samba server. I just tried to copy a 270MB file from a samba share to an XP machine. At first, the estimated time displayed as 141 minutes :( The odd thing is that if I then flood-ping from the server (in this case, I pinged my dsl router), the transfer completes in about 10 seconds. Hitting F5 repeatedly when browsing a share on the server

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.

rpm for r8168
Hello I've just been hit by one of the chipsets described at http://wiki.centos.org/HardwareList/RealTekRTL8111b. Because a) it does not work with the stock driver included in Centos 5.1 and b) I am very lazy and I do not like manually compiling modules each time a new kernel is installed (not to mention that I never forget anything, except for the important things which always go

Problem with driver disk on amd64
Hi, I have a really strange problem with a driver disk (http://wiki.centos.org/HardwareList/RealTekRTL8111b) on amd64. I'm remotly booting the system via isolinux-files, so I unfortunatly do not have access to relevant logs, all I can see the the primary console/screen. With i386, the driver disk works just fine and I can install via http. But with amd64, the installer complains no driver

Jumbo frames problem with Realtek NICs?
I was trying to do some performance testing between using iSCSI on the host as a diskfile to a guest vs the VM guest using the iSCSI device directly. However, in the process of trying to establish a baseline performance figure, I started increasing the MTU settings on the PCI-express NICs with RTL8168B chips. First bottleneck was discovering the max MTU allowed on these is 7K instead of 9K but
