Well, if you have some DVDs that you will like to backup, here are the steps to do it.

Note: For non-encrypted DVDs, meaning like personal home videos, non-commerical created DVDs, etc.. 🙂

Step 1:

dvdbackup -M -i /dev/dvd -o ./outputdir/

-M tells it to make a full backup, there are other parameters to backup selective chapters.

dvdbackup will create the DVD folder structure under ./outputdir/<volume-name>

Step 2:

mkisofs -dvd-video -o dvd.iso ./outputdir/<volume-name>

I managed to get hold of a Linksys WUSB54GC USB wireless-g adapter and a burnt copy of Backtrack 2 with Aircrack-ng.

So let’s get started then..Back Track 2 loaded with the rt73 drivers.

The following commands is to get your WUSB54GC dongle into the monitor/injection mode.

“ifconfig rausb0 up”

“iwconfig rausb0 mode monitor channel 1 rate 1M”

“iwpriv rausb0 forceprism 1”

“iwpriv rausb0 rfmontx 1”

I was trying out JanusVM in my VMware server. It’s a linux based OS with this few key components, openVPN, Squid, privoxy and Tor, packaged neatly into a VMware “appliance”.

Basically it provides a layer of security and privacy for most TCP based applications, like IM, web browsing, etc, even DNS requests are passed through Tor. Most importantly, it provides you with access to sites that are filtered off by your ISP transparent proxies.

FreeNAS is a free NAS server. Install on any x86 pc and convert it to a NAS serving CIFS (samba), FTP, NFS, RSYNC protocols.

Software RAID is supported at the following levels, 0, 1, 5. All configuration is done through the web interface.

Maybe I can put my old dual P3 system to good use.

When I plugged in my USB harddisk to my PC, to my horror, I started to hear some kind of clicking sound and the harddisk is trying to spin up and stop repeatively.

So I looked at my system’s dmesg messages and realised my HDD is a goner. My OS is unable to mount the vfat partition.

Remove the 2.5in harddisk from my USB casing and connected it back into my IBM X21, inserted an Ubuntu 5.10 LiveCD. Once Gnome desktop came up, I tried to mount the partition again, this time is successful !

I managed to save most of my data except 2 ISO files which I suspected they are residing on the harddisk bad sectors. I ran the harddisk diagnostic tool, guess what, bad blocks were detected.
Googled around and found a site with most of the different harddisk vendors’ Low Level Formatting tools. At the same time, I decided to “nuke” my harddisk.

Finally, I got both my boxes fixed. So I was happily connecting them together with a SC cable…. yah yah.. It’s only 15cm apart but still it’s a 1Gbps Fibre Channel link 😀

I decided to use dhcp for that link, since I haven’t tried configuring dhcpd before.

After configuring dhcpd on webmin, I tried starting it. The button still shows “Start Server”.

syslog presents:
Nov 9 19:53:24 localhost dhcpd: No subnet declaration for eth0 (10.x.x.x).
Nov 9 19:53:24 localhost dhcpd: Please write a subnet declaration in your dhcpd.conf file for the
Nov 9 19:53:24 localhost dhcpd: network segment to which interface eth0 is attached.
Nov 9 19:53:24 localhost dhcpd: exiting.

wtf, I actually configured for eth3 in the options. So i check /etc/dhcpd.conf, no mention of eth0. Got more pissed after starting the server several times, then I checked /etc/init.d/dhcp..

#Defaults
INTERFACES=”eth0″

So, ok. now I know the reason, changed it.. SAME ERROR !
This time i saw /etc/defaults/dhcp, added INTERFACES=”eth3″

Now it works. Installing Ubuntu on my 2nd box..

With reference to the wiki at ubuntu.com,

Edit /etc/modules:

For an intel cpu put the lines
piix
ide-core
above the line ide-cd

For an amd cpu put the line
amd74xx
above ide-cd

For a VIA Chipset put
via82cxxx
above ide-cd

my hdparm parameters

hdparm -c1 -d1 -X70 /dev/hda
-c1 enables 32bit IO
-d1 enables DMA
-X70 sets DMA to UDMA6

that’s all folks.
