bogus bond0 device showing up in /proc/net/dev
by Tom Georgoulias 02 Jun '10

02 Jun '10

I'm running into a situation where a bogus bonded interface named "bond0" is being created, in addition to the desired "bond2" interface. Can anyone confirm this? Anyone know why it's happening or what I do to get rid of it? I wanted to start my numbering scheme at 2 instead of 0, which I didn't think would be a problem. As you can see, I have no reference to bond0 in any of my configs: # grep bond /etc/modprobe.conf alias bond2 bonding # ifconfig -a | grep bond bond0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 bond2 Link encap:Ethernet HWaddr XXXXXXXXXXXXXXXXX # cat /etc/sysconfig/network-scripts/ifcfg-bond2 DEVICE=bond2 IPADDR=XXXXXXXXX NETMASK=XXXXXXXX NETWORK=XXXXXXXXX USERCTL=no BOOTPROTO=none ONBOOT=yes BONDING_OPTS="mode=1 miimon=100" # cat /etc/sysconfig/network-scripts/ifcfg-eth2 DEVICE=eth2 MASTER=bond2 SLAVE=yes HWADDR=XXXXXXXXXXXX ONBOOT=yes BOOTPROTO=none USERCTL=no # cat /etc/sysconfig/network-scripts/ifcfg-eth3 DEVICE=eth3 MASTER=bond2 SLAVE=yes HWADDR=XXXXXXXXXX ONBOOT=yes BOOTPROTO=none USERCTL=no The bond0 interface isn't doing any harm, as far as I can tell, except adding bogus data to ifconfig output and extra, useless charts in our system performance monitoring tools. # cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008) Bonding Mode: load balancing (round-robin) MII Status: down MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0 # cat /proc/net/bonding/bond2 Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008) Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: eth2 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 Slave Interface: eth2 MII Status: up Link Failure Count: 0 Permanent HW addr: XXXXXXXXXXXX Slave Interface: eth3 MII Status: up Link Failure Count: 0 Permanent HW addr: XXXXXXXXXXXXXX Any help is appreciated.

how to install ip6tables?
by Rudi Ahlers 02 Jun '10

02 Jun '10

Hi all, I'm sorry if this is a quick dumb one, but how does one install ip6tables? Running yum install ip6tables doesn't return anything, even with the rpmforge repository enabled: root@mercury:[~]$ yum install -y ip6tables Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * addons: mirrors.netdna.com * base: pubmirrors.reflected.net * extras: mirror.vcu.edu * rpmforge: fr2.rpmfind.net * updates: ftp.lug.udel.edu Excluding Packages in global exclude list Finished Setting up Install Process No package ip6tables available. Nothing to do Doing a google search for "how to install ip6tables", ironically, returns results on how to disable it. I have disabled it previously, but now want to re-enabled it as I want to play around with IPV6 & iptables. Any pointers will be appreciated. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Thin client system for X applications?
by Jim Davis 02 Jun '10

02 Jun '10

We're looking for what, years ago, I'd describe a s a X terminal -- something small, simple (and ideally cheap) that a user could display X applications on. I guess they're now called thin clients, but they now seem geared as seats on the web, and for this application we would need to be able display the results of running a homebrewed X application from a CentOS system, either through xdm, or ssh with X forwarding, or vnc. Running CentOS too on the thin client would be nice, but not a requirement. The HP t5545 looks right for size and price, but I can't tell if it could support displaying arbitrary X apps.

Shutdown/poweroff does not power off machine
by Scot P. Floess 02 Jun '10

02 Jun '10

I've got a Dell Optiplex GX240 I am running CentOS 5.4 (kernel 2.6.18-164.9.1.el5.centos.plus)... When I had Fedora 11 and 12 on it, I could issue a poweroff command and the machine would power itself off. However, under CentOS it doesn't turn the machine off whatsoever. When it completes, the machine is still running with a message of "system halted." Then I have to physically hit the power button to turn it off... I believe at some point I did try to issue a shutdown command - but had the same results... Anyone have any recommendations or suggestions? Thanks ahead of time :) Scot P.

Error: when updating the latestt kernel 2.6.34 in centos 5.5
by 886886 backyes 02 Jun '10

02 Jun '10

Hi, I encounter a error when installing the latest kernel 2.6.34 in centos. Steps: 1. download source code. 2.tar -xvf 2.6.34.tar.gz 3.use the .config file of current system in /boot directory. 4.make ,make modules_install, make install, 5.reboot. 6.error:: accur. Reading all physical volumes. This may take a while ... Activating logical volumes Volume group "VolGroup00" not found Creating root device. Mounting root filesystem. mount: could not find filesystem"/dev/root" setting up other filesystems. ... After comparing the latest initrd.img and the current system initrd.img . The differnce below: the currenet system has more modules before excuting the LVM operations. these modules is dm-mem-cache.ko , dm-message.ko and dm-raid45.ko which depends the others. I know the centos 5.5 ' s kernel is 2.6.18. which has dm-raid45.ko module. I do not know which changes to 2.6.34 about LVM. I think the errro is about the LVM. Anyone can give me answer or advice. Thanks. -- Best regards to you ! >From Yanfei wang Addr: Anhui China Email:backyes@mail.ustc.edu.cn <Email%3Abackyes(a)mail.ustc.edu.cn> QQ:23475391

Setting up a printer without having one
by Marko Vojinovic 02 Jun '10

02 Jun '10

Hi folks! :-) I am supposed to configure this fresh install of CentOS 5.5 to work nicely with the HP 1010 printer, once it gets connected to the computer (probably via usb, but I cannot be sure). The problem is that I will not be anywhere near the machine when the printer actually gets plugged in, and hp-setup refuses to do anything until that happens. So how does one configure a to-be-used-in-the-future printer, without actually having one plugged in? People who are going to use the machine are noobs, and unlikely to be able to set up the printer themselves, so it would be a good idea if I could do it in advance. I haven't done anything like this before, and would be grateful for any pointers. TIA! :-) Marko
