How to Generate graph of IOZone output

Output of  the command

iozone -a -+u -g 2G -b file-au2g.ods

provides benchmark on the filesystem(ext4) which includes various reports namely
writer report
re-writer report
reader report and others
This (howto)graph is generated for only writer report

a Data range used
b select insert chart

In the chart wizard, selected line(c) and line type-> smooth(d)(its your choice what kind of chart you want)

Select e to define the data range

Select the data range f which gets reflected in g

Graph takes its form

No need to fiddle with data ranges and data series

Enter the title, x axis and y axis label

Without consensus..

yesterday as I was carrying out my mundane task with my wa3002g4 - regular disconnection issue still persisting - but with all that and no program accessing the network the wlan indicator was blinking as in being accessed and with the firewire it was evident that the network was being used without my consensus and now was very eager to find which program was accessing the network so with little search, the very regular form of suggestion - netstat/tcpdump/wireshark was propping up so with the tcpdump found that the

ec2-184-73-194-227.compute-1.amazonaws.com.www

was accessing my box without permission. but even before checking which was the process that was doing it. It stopped - later on found that it was the amazon site doing its job - but how could they do that with no consensus.

Latest driver for HP Deskjet F4488

The default hplip 2.8.2 on ubuntu 8.04 was not recognizing the deskjet_F4400 printer so the latest driver (hplip-3.10.6.tar.gz) at the HP was installed from src.
Almost all the steps are specified in hplipopensource.
If the default hplip is installed, remove it.

Download the src from http://hplipopensource.com/hplip-web/downloads.html

extract the tar.gz file

./configure --with-hpppddir=/usr/share/ppd/HP --prefix=/usr --enable-qt4 --enable-doc-build --enable-cups-ppd-install --disable-foomatic-drv-install --disable-foomatic-ppd-install --disable-hpijs-install --disable-policykit --disable-cups-drv-install --enable-hpcups-install --enable-network-build --enable-dbus-build --enable-scan-build --enable-fax-build

make

and

sudo make install

add username to the lp group

sudo usermod -a -G lp $USER

now connect the usb printer and power on the printer... if not done this way the hplip will not detect the device

su hp-setup 

will activate qt4 based config dialog... follow the instruction as specified and by opting for test prn page the following will be printed out..

All the features of the all in one printer has not been used on my box
In my case the cups daemon was disabled... to enable it use
sudo sysv-rc-conf
and start the service using
/etc/init.d/cupsys start

I have been using the scanner of F4488 without any problem whatsoever for quite some time now on ubuntu 8.04 and the application used is Xsane Image Scanner(v-0.995). It working fine for me. Some of the screen shots of the application in action.

GNU/Linux came to the rescue.

wifiLinux saved my day. Yet another encounter with itchy scenario which I wished Ginnie could have completed and I could devote my time to bit more constructive work.
One of the typical answer that one gets when dealing with  msoft os is any problem is plainly/blindly blamed on virus. In the current senario it was the corrupt driver or inappropriate driver that was giving the problem BSOD.

The wifi wasn't working properly and wasn't sure whether it was the driver or the device itself(atheros -AR242x 802.11abg Wireless PCI Express Adapter )
so the linux(ubuntu) was used with the atheros driver to check the functionality of the device. the instruction(http://nothingcanstopu.blogspot.com/2009/06/ubuntu-804-atheros-communications-inc.html) previously scribbled came in handy and worked like a charm. no probs whatsoever.

The installation of OS using pen drive is almost becoming a defacto standard with the arrival of netbook which doesn't have an internal cd/DVD drive. there are almost Mton of article on how to make the usb stick bootable  -
for vista too one can make usb bootalbe with novicorp - wintoflash

With freebsd the installation is much simpler than linux as we just need to create a slice which latter on is partitioned. The GUI is as effective as any linux version. wasn't able to get the atheros wifi working even though the inbuilt option of atheros driver was present.

Ubuntu 8.04 - Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01) configuration

Disable the Atheros hardware driver by selecting system->Administration->Hardware Driver

Reboot

Checkout the source madwifi(Multiband Atheros Driver for WiFi) from

svn co https://svn.madwifi-project.org/madwifi/branches/madwifi-hal-0.10.5.6

Use make
**sudo apt-get install build-essential

and sudo make install to install the madwifi driver

edit the /etc/modules using any editor and enter ath_pci at the end
simple one gksudo gedit /etc/modules

ath5k - a complete FOSS wireless driver for atheros WLAN chipset

I have a Dell Vostro A840 - having atheros wifi card and unfortunately ubuntu 8.04 doesn't support the driver i.e the restricted driver - by default it supports madwifi (Multiband Atheros Driver for Wireless Fidelity) driver but the HAL part is closed.

Good news ath5k is open every where - so go ahead and have a peak

The bootchart app gives a graphical o/p of the boottime process. Even after disabling some unwanted services it's bit slow..
