Hello listmates, As some of you may know we have been having a really bad problem with Realtek Semiconductor Co., Ltd. RTL-8169 cards. See here for details: http://forum.nginx.org/read.php?24,140124,140224 So now my question is, what PCI 1 Gbit/s Ethernet adapters should I use under CentOS? If you have had a consistent positive experience with any particular chipset/brand please speak up.

Hi all, Does anyone have, or know of a comparison chart of the different network adapters, i.e. 1GB / 10GB, Infiniband, etc. And if possible with a few top brand NIC's and switches listed as well. I would like to see, for example, what the max throughput is of a 1GB NIC (and this could probably differ from PCI to PCIE-x1 to PCIE-x4), and 10GBE. Different switches would probably also have

I'm tuning a samba 4.3 install on freebsd and I'm confused about aio settings. I've loaded the freebsd aio kernel module and tried various values or aio read size and aio write size, but it seems to make no difference in the speed. Using MS diskspd against a samba share from a fast zfs pool I get something like 25MB/s tops. That's well below the capacity of my Gb network and

...t is the string "imap". The service type surely is IMAP, and from what I can gather of the expected format of the digest-uri triplet from the comments in the code it should be the first component. Is this just a case of inverted logic or am I mistaken ? Thanks, -- Dominic <dom at wirespeed.org.uk>

Group, My linux box, running with Centos-5.5, is showing up (??) a pseudo network interface for Eth0. On Switch where my Eth0 is connected, observed 2 MAC-Addresses. If a DHCP server present in LAN, the second pseudo interface is picking up a DHCP IP Address too. Furthermore you can ping both Eth0 ip and Psedo Eth0 IP from the switch. The intensity of the problem is more when port-security is

Hello LARTC gurus. I''m new to this list and have a mind boggling problem that I cannot resolve. Let me describe my problem: We have a custom built wireless camera comprised of an IP encoder and a BitsyX running Linux. It communicates to an antenna unit (Bitsyx) which plugs into a Windows machine with a digitial video recorder: [IP Video Encoder] -> [Linux Box 1] - 2Mbit Wireless

Hello, I am desperately trying to get pci-passthrough to working. I want to pass a tg3 nic to domU. when booting domU I get a lot of messages: pcifront pci-0: pciback not responding!!! in domU, "ifconfig eth... adress up" hangs for 2 minutes, finally ifconfig -a shows a correct setting with no data transmitted rx/tx The IP Adress is being assigned, but there is no data transmission

OK, here it is. Near perfect bandwidth calculation for ADSL users. Patch iproute2 with the HTB stuff and then this: It''s still a hack (as far as I can tell) because we are patching the rates tables, and hence I think it is only loosly coupled with the actual calculation of bytes in each bucket. However, it works very nicely for me! I have only been lightly testing with
