lost and found ( for me ? ): March 2012

install dnsperf 2.0 on Linux Mint 12

dnsperf is DNS stressing tool provide by Nominum.

You can get it from the following URL.

http://www.nominum.com/resources/measurement-tools

As for RHEL , there are RPM packages for RHEL4 i386 , RHEL 5 i386 , RHEL6 x86 64.

As for Debian based , there are no deb packages.

I’ll install this on Linux Mint 12 from the source.

# tail -1 /etc/lsb-release

DISTRIB_DESCRIPTION="Linux Mint 12 Lisa"

# uname -ri

3.0.0-17-generic x86_64

download the source

dnsperf-src-2.0.0.0-1.tar.gz

# tar xzvf dnsperf-src-2.0.0.0-1.tar.gz

# cd dnsperf-src-2.0.0.0-1/

Seen from README , BIND 9.4.0 or greater need to be installed to compile dnsperf 2.0

1. Make sure that BIND 9 (9.4.0 or greater) is installed, including libraries

and header files, and that the isc-config.sh program distributed with BIND

is in your path.

Befre installing dnsperf 2.0 , I’ll install BIND 9.9.0

# tar xzvf bind-9.9.0.tar.gz bind-9.9.0/

# cd bind-9.9.0/

# ./configure

# make

# make install

# /usr/local/sbin/named -V

BIND 9.9.0 built with defaults

using OpenSSL version: OpenSSL 1.0.0e 6 Sep 2011

install dnsperf 2.0

# cd dnsperf-src-2.0.0.0-1/

# sh configure

Senn from README , it describes that:

Note: many versions of bind do not correctly install the <isc/hmacsha.h>

header file, so if the compilation fails, obtain this file from the BIND

source distribution, and install it in the appropriate place.

where is hmacsha.h …

# locate hmacsha.h

/home/zzz/my_works/bind-9.9.0/lib/isc/include/isc/hmacsha.h

and which directory should I put it ??

under /usr/local/include/isc directory ?

# ls /usr/local/include/isc/

app.h hex.h netaddr.h sha2.h

assertions.h hmacmd5.h netdb.h sockaddr.h

atomic.h httpd.h offset.h socket.h

base64.h int.h once.h stdio.h

copy hmacsha.c to /usr/local/include/isc directory.

# cp /home/zzz/my_works/bind-9.9.0/lib/isc/include/isc/hmacsha.h /usr/local/include/isc

try again

# sh configure

okay.

Small tips : How find/kill zombie processes

There are many ways to find out zombie processes , so this is one of examples.

# cat /etc/centos-release

CentOS release 6.2 (Final)

find zombie processes

# top -b -n 1 | grep Z

6072 root 20 0 0 0 0 Z 0.0 0.0 0:00.09 dumpcap <defunct>

6075 root 20 0 0 0 0 Z 0.0 0.0 0:00.11 dumpcap <defunct>

# ps aux | awk '{ print $8 " " $2 }' | grep -w Z

Z 6072

Z 6075

kill zombie processes

# kill -9 6072

# kill -9 6075

how to install CentOS 6 via USB stick

At first , I made an installation USB stick for CentOS6 with unetbootin tool on Linux Mint 12 machine , however I can’t install CentOS6 via that USB stick created by unetbootin

unetbootin does not seem to support CentOS 6 as of now…

I could install CentOS 6 via USB stick by following instructions.

many tnx !

http://www.phoenixxie.com/?p=11

there are two ways to make an installation USB stick

- use CentOS iso

- use CentOS Live iso

the latter is easier. ( IMO )

[ use CentOS iso ]

download iso

# tail -1 /etc/lsb-release

append initrd=initrd.img method=hd:sdc2:/

the line “method=hd … “ dpends on your environment. ( sda2 or sdd2 or sdc2 )

In my case , I could install CentOs6 when specifying sdc2.

( there are two HDDs have been installed in my PC )

# umount /mnt/BOOT

# umount /mnt/DVD

get things done.

install CentOS6 by using that USB stick.

[ use CentOS Live iso ]

You can install CentOS6 using CentOS Live version.

download CentOS live CD and do the following command.

KVM : add a storage to running VMs by “virsh attach-disk” command

# tail -1 /etc/lsb-release

DISTRIB_DESCRIPTION="Linux Mint 12 Lisa"

# uname -ri

3.0.0-16-generic x86_64

# libvirtd --version

libvirtd (libvirt) 0.9.2

# virt-manager --version

0.9.0

# kvm --version

start a VM ( this VM is openfiler 2.99 )

virsh # start filer01

The VM , fieler01 , has three storage devices , sda , sdb and sdc.

[root@filer01 ~]# dmesg | grep sd[a-z] | grep -i attach

sd 0:0:0:0: [sda] Attached SCSI disk

sd 0:0:1:0: [sdb] Attached SCSI disk

sd 1:0:1:0: [sdc] Attached SCSI disk

add one more storage via virsh

on the KVM host , create a storage file for that VM

# qemu-img create -f raw filer01-data1.img 1G

on the KVM host , add that storage as “/dev/sdd” to that running VM

virsh # attach-disk --driver file filer01 /var/disk1/libvirt/images/filer01-data1.img sdd
error: Failed to attach disk
error: internal error unsupported driver name 'file' for disk '/var/disk1/libvirt/images/filer01-data1.img'

nnn , error ,,

Let’s check libvirt.log.

/var/log/libvirt/libvirtd.log

error : qemuDomainAttachDeviceDiskLive:3994 : internal error unsupported driver name 'file' for disk '/var/disk1/libvirt/images/filer01-data1.img'

nnnn , I’m not familiar with virsh command…

How about this ?

virsh # attach-disk filer01 /var/disk1/libvirt/images/filer01-data1.img sdd --type disk

Disk attached successfully

I could add the storage ( /dev/sdd )

[root@filer01 ~]# dmesg | grep sd[a-z] | grep -i attach

sd 0:0:0:0: [sda] Attached SCSI disk

sd 0:0:1:0: [sdb] Attached SCSI disk

sd 1:0:1:0: [sdc] Attached SCSI disk

sd 2:0:3:0: [sdd] Attached SCSI disk

The following is an excerpt of xml file of the VM to which I added a storage via virsh attach-disk

</disk>

The following is via virt-manager

</disk>

let’s create a partition on /dev/sdd

warning … partition table is GPT …
