Path Analyzer Pro

looking for a visual traceroute program on Linux I found Path Analyzer Pro

Path Analyzer can be downloaded for free evaluation and is available on Windows (XP, Vista and 2003 Server) and recently as Beta version for Linux (Debian and RedHat).

I downloaded the papro-2.6-5.i386.rpm and installed it on SLED11 SP2 (SuSE Linux Enterprise Desktop).
After installation I wanted to run the program and got the following error:

# /usr/bin/papro
/usr/bin/papro: error while loading shared libraries: libpcap.so.0.8: cannot open shared object file: No such file or directory

I linked the newer libpcap to the required libpcap and the program started.

# ln -s /usr/lib/libpcap.so.0.8.1 /usr/lib/libpcap.so.0.8

JDiskReport

Recently someone brought the application to my attention. It can be downloaded at JGoodies.com
I downloaded the jdiskreport-1_3_0.zip for a SLED10 SP1 install with java version "1.4.2_17".
Unzipping the file extracts the following:

o LICENSE.txt - the license agreement
o README.txt - this readme file
o RELEASE-NOTES.txt - information about changes and bug fixes
o jdiskreport-1.3.0.jar - a signed executable JAR file

The README explains how to start the application:

To run JDiskReport from a command-line, change directory to where the JAR-file is located. Then execute:

java -jar jdiskreport-1.3.0.jar
or
java -jar /path_to_directory/jdiskreport-1.3.0.jar

Nice tool, it shows what's eating up all your space. You get a graphical output instead multiple lines of text, when using "du".

One of the view modes is a Pie Chart of "File sizes in /directory". "Top 50" breaks the output down to a list of 50 largest files in /directory, "Size Dist" shows the Distribution of sizes in /directory, "Modified" gives another Bar Chart with Distribution of modification dates in /directory and "Types" shows the Distribution of file types in a /directory.




JDiskReport takes up 1.7 MB in the /usr/local/bin/jdiskreport dir, I installed it in:

Kiwi - live USB image

There's a description Live USB stick on opensuse.org which I pretty much followed.

First I installed:

kiwi-desc-livesystem-1.62-25.1
kiwi-desc-usbboot-2.38-34.1
kiwi-2.38-34.1
kiwi-tools-2.38-34.1

I choose the option "downloading the most recent packages from the internet".

/usr/share/kiwi/image/usbboot/suse-10.3/config.xml

and added the repository:

<repository type="yast2" status="replaceable">
<source path="ftp://mirrors.kernel.org/opensuse/distribution/10.3/repo/oss"/>
</repository>
<repository type="yast2" status="replaceable">
<source path="ftp://mirrors.kernel.org/opensuse/distribution/10.3/repo/non-oss/"/>
</repository>

I didn't set the update repository in
/usr/share/kiwi/image/kwliveCD-suse-10.3/config.xml

When I set the update repository to
<repository type="rpm-md" status="replaceable">
<source path="http://download.opensuse.org/update/10.3/"/>
</repository>
kiwi exited with the following error:

opensuse103:~ # kiwi --prepare /usr/share/kiwi/image/kwliveCD-suse-10.3 --root /media/vmware/kiwi-tmp --add-profile KDE --logfile terminalApr-22 04:59:15 <1> : Setting log file to: terminal

Apr-22 04:59:16 <3> : Element image has extra content: text

Apr-22 04:59:16 <3> : KIWI exited with error(s) done
opensuse103:~ #

Instead I replaced the entry with the same I had put in: /usr/share/kiwi/image/usbboot/suse-10.3/config.xml

There's only one .checksum.md5 file. It is in /usr/share/kiwi/image/usbboot/suse-10.3/
Copy it and create a new one with:

cp .checksum.md5 .checksum.md5.old
md5sum config.xml > .checksum.md5

Cleanup is only necessary if kiwi was run before, there wasn't anything to do here.
For anyone who already created the two directories: kiwi-tmp and kiwi-image a removal is recommended if you are going to use the same path. Remove these two directories with
rm -rf /tmp/kiwi*

(I actually created them in a different directory, so instead of /tmp, the image was on my USB drive /media/usb-dvd/

Finally, after all these preparations I run:

kiwi --prepare /usr/share/kiwi/image/kwliveCD-suse-10.3 --root /media/usb-dvd/kiwi-tmp --add-profile KDE --logfile terminal

Kiwi initiates downloading and installing all these RPMs. Good thing that progress is shown on the right hand of the screen:

-> ftp://mirrors.kernel.org/opensuse/distribution/10.3/repo/oss/suse/i586/tpctl-4.17-131.i586.rpm
tpctl-4.17-131.i586.rpm ########################################################################### [ 83%]
->

And finally at the end:

Apr-22 05:35:38 <1> : KIWI exited successfully



Then I continued to create the compressed image and initrd out of kiwi-tmp.

mkdir /media/usb-dvd/kiwi-image
kiwi --type usb --create /media/usb-dvd/kiwi-tmp -d /media/usb-dvd/kiwi-image --logfile terminal


Now it was time to plug in my usbstick and unmounted it with:

umount /dev/sdd

There was no other partition on the drive. If there is so, then "mount" will show them.


To create the bootstick enter:

kiwi --bootstick /media/usb-dvd/kiwi-image/initrd-usbboot-suse-10.3.i686-2.1.1.splash.gz --bootstick-system /media/usb-dvd/kiwi-image/openSUSE-10.3.i686-2.5

Following messages appeared on the screen:

opensuse103:/media/usb-dvd # kiwi --bootstick kiwi-image/initrd-usbboot-suse-10.3.i686-2.1.1.splash.gz --bootstick-system kiwi-image/openSUSE-10.3.i686-2.5

Enter the device name output in the last but one line. In my case: /dev/sdd.

Apr-22 05:14:57 <1> : Your choice (enter device name): /dev/sdd

Kiwi partitioned the stick and dumped the image to the stick:

Apr-22 05:17:12 <1> : Creating partition table on: /dev/sdd done
Apr-22 05:17:26 <1> : Rereading partition table on: /dev/sdd done

Apr-22 05:19:30 <1> : Removing HAL lock done
Apr-22 05:19:30 <1> : KIWI exited successfully

Kiwi created the following partitions:

/dev/sdd1 on /media/disk-2 type ext2 (rw,nosuid,nodev)
/dev/sdd3 on /media/disk-3 type ext2 (rw,nosuid,nodev)
/dev/sdd2 on /media/disk-4 type squashfs (rw,nosuid,nodev)

/dev/sdd2 is the compressed image, initrd and kernel.
/dev/sdd3 contains packages and stuff that doesn't fit into the 700+ MB initrd. It's read/writable so that thing that get written to the USB stick are put here.
/dev/sdd1 is the boot partition, including grub.

Boot a machine with the usbstick plugged in, don't forget to set the BIOS to boot from USB and you'll get a LIVE opensuse 10.3 on a USB stick.
