similar to: Jumbo frames problem with Realtek NICs?

After successfully getting higher MTU to work on my Realtek NICs, I started testing the impact of higher MTU on file transfers using NFS exported ramdisk to ramdisk. The results were unexpected. The higher the MTU on the sending NIC, the lower the file transfer speed. I tested by using time cp to copy a 1GB file (In case compression might affect the results, so I dd the test file from the CentOS

Realtek is "real" good about getting drivers for their chips into the kernels as soon as possible. They are one of the few vendors that I have never had a problem with built in support... Mike McCarthy On 06/03/2016 08:03 AM, Phil Manuel wrote: > You can get the Linux driver from >

Hi list, I'm planning to buy a mobo (z170-K) that has Realtek 8111GR (nic). I've tried to search on google about support on C7 but can't fine anything. There is a way to check if supported? Is the Realtek 8111GR supported or I must change mobo? Thanks in advance.

Dear Friends of the Community Here by I request some help, now Install Centos 5.0 in DELL 3020 one machine installation took correctly, but after installation I find that the network card that brings integrated computer does not recognize the eth0. 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

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

I have a strange problem on one machine where eth0 gets killed when I add a virtual interface. It's got something to do with the NIC ordering or with the xen network script having a problem with multiple NICs and virtual interfaces. I could need some help/comments on this. Some history: I added a NIC (chip identifies as Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit

Hi, I have a new mainboard with a Realtek RTL8111B / RTL8168B NIC. In 5.1 are no driver integrated for this nic, but there is driver disk: http://wiki.centos.org/HardwareList/RealTekRTL8111b and http://wiki.centos.org/HardwareList/RealTekRTL8111b?action=AttachFile&do=get&target=r8168-2.6.18-53.el5-i686-x86_64.img.zip Can I integrate this driver do the CentOS 5.1 ISO or can i use this

You can get the Linux driver from http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=5&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false#RTL8111B/RTL8168B/RTL8111/RTL8168%3Cbr%3ERTL8111C/RTL8111CP/RTL8111D%28L%29%3Cbr%3ERTL8168C/RTL8111DP if you can't find it under C7 Regards On Fri, Jun 3, 2016 at 8:11 PM, Alessandro Baggi <alessandro.baggi at

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 is the output from lspci 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI

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

Hello list I have a shutdown problem. I have a machine with gigabyte GA-G33M-DS2R motherboard. Integrated network card is Realtek 8111B. I can not wake the computer after I shutdown it from FreeBSD. It is a dualboot system - windows xp and freebsd. If I shutdown the computer from windows - later I can wake it up with magic packet. Even if i shutdown the machine on the boot menu with the power

Hello all, Not sure if I am completely missing something but here goes. I have XCP 1.0 running without any issues. I have the mtu set on both the storage network, the corresponding PIF, and the VIF to 9000 and when displayed in ifconfig it shows that this is indeed true. I have several CentOs 5.6 VMs running in HVM mode (i.e. no xen kernel) which attach to the the storage network through these

Hi, Last friday I changed the NIC in two of our Samba servers from a 3com 905b (100mb) to a 3com 2000T (1000mb) to take advantage of our new switch which supports gigabit. One of the workstations (XP SP1, with all subsequent patches and hotfixes and with an onboard Realtek 8139) then started to have problems with the two Samba servers with the new NIC's. It could see the network

Dear, I''ve attempted to upgrade a Xen box from 3.1.2 to 3.2.1. Unfortunately it has been a partial success only. At this point I''m really stuck with a network problem that affects my HVM machines (Linux PV run fine). The really odd thing is that everything seems to work properly, except that the "vif" network interfaces in dom0 seem to have only dropped TX packets for

Greetings, I am tearing my hair at getting this to work under centos 5.5/Ubuntu 10.04. Any suggesstions (Repos, RPMs etc)? My MB Intel embedded NIC blow up after a lightning (Mumbai get _real_ heavy mansoon rains inter alia). I want this to make work under Centos 5.x (and 6.x subsequently who DVD I have been downloading with a pithy 128kbps connection). -- Regards, Rajagopal

I found (and fixed) a problem with my realtek onboard 8139 controller. dhcpd server sends filename "pxelinux.0" but realtek requests "pxelinux.0\377" (i.e. the octal character 377 is appended), resulting in a file not found during the tftpd phase. I fixed this by adding a mapping to tftpd: # strip ending garbage from filenames (Realtek PXE bug) r ^([[:graph:]]*)(.+)$ \1

Greetings- I'm attempting to get CentOS 5.5 x86 (yes, very specific version required for specific software usage scenario... don't ask) running on an Intel D425KT mini-ITX motherboard. Everything works fine, with the exception of the onboard ethernet, which is a Realtek RTL8105E chip. The stock CentOS installation attempts to use the r8169 driver, which does not work. I've been around

I have an Asus P5Q-WS running FreeBSD 7 and the onboard Realtek NIC's are not being detected.
