Hi all, I have two HP DL145 G1 machines, running centos4 (2.6.9-22.0.2.ELsmp). Nics are recognized as: eth0: Tigon3 [partno(BCM95704) rev 2002 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:00:1a:19:f1:05 eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] Split[0] WireSpeed[1] TSOcap [1] eth1: Tigon3 [partno(BCM95704) rev 2002 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet

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

Hi all! I want to assign a physical network card (e100) to a domU: I think Dom0 is ok but domU does not recognize the pci nic. into DomU I don''t know wath should I see: I have nothing in dmesg nor in messages... Into Dom0 I have this modules.conf: options pciback hide=(0000:03: 08.0) install e100 /sbin/modprobe pciback; /sbin/modprobe --ignore-install e100 This is dmesg: pciback

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

Hi all, I am trying to configure a Dom U to act as a firewall and therefore I need to pass one of the two ethernet cards to the Dom-U. I configured the Xen kernel to build pciback as a module and I am passing the hide option via boot parameters. I boot the pv machine via pygrub and I am able to see the ethernet device in Dom U as follows: Dom-U#lspci 02:00.0 Ethernet controller: Broadcom

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, Thanks to everyone involved in the Xen project. I think it is great and can''t wait to get my hands dirty with it. In the meantime, I cannot boot Dom0 on an ibm x335 and I am not sure what the problem is. Any insights are welcome. Here is what my grub.conf file looks like: title Fedora Core (2.6.8-1.521) root (hd0,0) kernel /vmlinuz-2.6.8-1.521 ro root=/dev/sda9

Hey guys, I am running gluster over infiniband, and I have a couple of questions. We have four servers, each with 1 disk that I am trying to access over infiniband using gluster. The servers look like they start okay, here are the last 10 or so lines of a client log (they are all identical): 2008-10-07 07:18:40 D [spec.y:196:section_sub] parser: child:stripe0->remote1 2008-10-07 07:18:40 D

Hello, I am confused by a problem I am having getting Dovecot to authenticate users with DIGEST-MD5. I am receiving the error message, "Unexpected service type in digest-uri". (cvs: mech-digest-md5.c, line 407) From an examination of the code it is clear that a check is performed to see if the first component of a the digest-uri triplet is the string "imap". The service

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

Yes, FOU will probably get the highest

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

Recent SUP. Installed on Dell PowerEdge 4600. Getting tons of: Sep 30 12:23:16 zige /kernel: bge0: gigabit link up Sep 30 12:23:46 zige last message repeated 98 times Also getting some TCP retransmits. This causes noticable delays in pretty much everything I do now. Not a problem prior to the SUP. I was on 4.8-STABLE before. When pulling/replacing cables, it went into a mode where it would

hello, i'm not a heavy samba user in general (works without any serious tweaking on my modest home network), but one of my clients is and we are seeing some strange behavior. perhaps it makes sense to someone with more clue. if not, i could use some advice in how to figure out what is going on. the setup: a couple dozen windows clients (xp pro 64bit & vista ultimate 64bit) taking

Greetings, I recently installed CentOS 5 on Dell PE 1750 server. I have noticed that the speed and duplex settings are 100 Half Duplex. I tried to change the duplex settings to full, but no success. I got the error message "Cannot get current device settings: Operation not supported". Does anyone else experience this issue?. Below is the error message and some more details about my box.
