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

nnn , error .. there’s no hmacsha.h: ..

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.

# make

Linux KVM : connect to a Linux Mint12 VM via virsh console

small tips

how to use virsh console.

KVM host : Ubuntu 11.10

VM : Linux Mint 12

[ on the KVM host (Ubuntu 11.10 ) ]

confirm the VM has serial ports.

# virsh dumpxml Mint12-64-1 | less

</serial>

[ on the VM ( Linux Mint 12 ) ]

make /etc/init/ttyS0.conf file

# cat /etc/init/ttyS0.conf

start on stopped rc RUNLEVEL=[2345]

stop on runlevel [!2345]

respawn

exec /sbin/getty -L 115200 ttyS0 vt 102

“start ttyS0”

# start ttyS0
ttyS0 start/running, process 703

edit /boot/grub/grub.cfg

By default , grub.cfg is read-only permission.

add write permission.

# chmod u+w /boot/grub/grub.cfg

edit grub.cfg ( add red lines )

Compile QEMU-KVM on Linux Mint 12 64bit ver.

Here’s an explanation of how to switch from the KVM installed via apt-get to the KVM building from the source.
I’ve installed the KVM ( kvm , libvirtd , virt-manager ) via apt-get and it works well.

This explanation is:

Use KVM kernel modules installed via apt-get ( kvm , kvm_intel or kvm_amd )
Use qemu-kvm built from the source.

# uname –ri
3.0.0-14-generic x86_64

# tail -1 /etc/lsb-release
DISTRIB_DESCRIPTION="Linux Mint 12 Lisa"

# kvm –version <- installed via apt-get
QEMU emulator version 0.15.0 (qemu-kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard

# libvirtd –version <- installed via apt-get
libvirtd (libvirt) 0.9.2

# virt-manager –version <- installed via apt-get
0.9.0

- the preparation before building qemu-kvm from source

Install the following packages via apt-get to build qemu-kvm.

# LANG=C apt-get install gcc gcc-4.6 libsdl1.2-dev make libz-dev uuid-d
ev libasound2-dev gcc libc6-dev zlib1g-dev linux-headers-3.0.0-14

Get the latest KVM source ( qemu-kvm-1.0.tar.gz ) from http://sourceforge.net/projects/kvm/files/

# ls
qemu-kvm-1.0.tar.gz

- compile qemu-kvm

qemu-kvm does not include kvm-kmod ( KVM kernel modules )
I use KVM kernel modules which I have installed via apt-get.

# tar xzvf qemu-kvm-1.0.tar.gz
# cd qemu-kvm-1.0/

# ./configure --prefix=/usr/local/kvm
KVM support yes
# make
# make install

# ls /usr/local/kvm/*
/usr/local/kvm/bin:
qemu-ga qemu-img qemu-io qemu-nbd qemu-system-x86_64

/usr/local/kvm/etc:
qemu

/usr/local/kvm/share:
qemu

# /usr/local/kvm/bin/qemu-system-x86_64 --version
QEMU emulator version 1.0 (qemu-kvm-1.0), Copyright (c) 2003-2008 Fabrice Bellard

make sure your OS has loaded KVM kernel modules.

# lsmod | grep kvm
kvm_intel 61643 0
kvm 383781 1 kvm_intel

- start the VM with qemu-kvm 1.0

I’ve already had the VM ( CentOS 6.2 ) , so I’ll fly this VM with qemu-kvm 1.0.

# /usr/local/kvm/bin/qemu-system-x86_64 -m 1024 -hda /var/disk1/libvirt/images/centos6-vm1.img -monitor telnet::4444,server,nowait -vnc :0 –daemonize

- Connect to the VM via VNC

check the PID of the VM.

# ps aux | grep qemu-system | grep centos
/usr/local/kvm/bin/qemu-system-x86_64 -m 1024 -hda /var/disk1/libvirt/images/centos6-vm1.img -monitor telnet::4444,server,nowait -vnc :0 –daemonize

check the listen ports

# lsof -np 25904 | grep -i tcp

qemu-syst 25904 root 3u IPv4 2434434 0t0 TCP *:4444 (LISTEN)

qemu-syst 25904 root 14u IPv4 2432962 0t0 TCP *:5900 (LISTEN)

TCP port 5900 is for VNC access ( -vnc :0 )
TCP port 4444 is for qemu-monitor access. (-monitor telnet::4444,server,nowait )

start VNC viewer

$ vncviewer 127.0.0.1::5900 ( or vncviewer 127.0.0.1:0 )

- access to the qemu monitor via telnet

# telnet 127.1 4444

The binary file of qemu-kvm installed via apt-get is /usr/bin/kvm which is the symbolic link file of /usr/bin/qemu-system-x86_64.
