Xandros Data Structure

Given: Laptop o/s:Xandros 3.0.3 Business Ed

Question: USB port recognizes external data storage (hdd in case) with installed o/s Xandros 3.0.3 Business Ed (same as laptop), BUT freeze occurs, rendering laptop system slow/frozen and rendering external hdd in case unusable and unreadable. In a desktop, this would likely be the result of an IRQ conflict. What's happening here?

What is the data structure of Linux? Is it FAT? Is it NTFS? Is it something else?

Please forgive me but I'm a little new to Red Hat (RHEL 5). I'm using rysnc to backup critical data and to a second disk; here is what I'm typing at the command line rsync -rvgal /data/disk1/share /data/backup/share. It appears that the softlinks are not transfered to the backup drive and some of the links point to data not located in the source folder (/data/share). After reading the rsync man page I was a little confused about the L option (vs the l option). In order to ensure that the linked files are moved should I type the below:

rsync -rvgaL /data/disk1/share /data/backup/share

A million thanks,

Hi All,

I have Redhat5.3 running on my machine. I have 800 GB data mounted on /dev/sdb1 partition. When I reboot my machine and after reboot the data is not available in /data folder. I have already use mount command but its not working.

Can anyone help me how to retrieve those data.

hi guys,

thanks in adv for looking through the long winded post...

i'm trying to cat a bunch of text files together into one, but i'm running into problems and i think it's because of how 'find' is working, but i'm not really sure. here's the command i'm using


Code:

find . -name '*.dat' -exec cat {} \; > out.txt

my data structure looks like

dir1
f1.dat
f2.dat
f3.dat
f4.dat
f5.dat
f6.dat
f7.dat
f8.dat
f9.dat
f10.dat
dir2

f10.dat
dir4

f1.dat
f2.dat
f3.dat
f4.dat
f5.dat
f6.dat
f7.dat
f8.dat
f9.dat
f10.dat

so I "think" in my cat'd file I'm getting the order like this,

dir1f1
dir1f10
dir1f2
dir1f3
dir1f4
dir1f5
dir1f6
dir1f7
dir1f8
dir1f9
dir2f1
dir2f10
dir2f2
dir2f3
dir2f4
dir2f5
dir2f6
dir2f7
dir2f8
dir2f9
etc....

but maybe it's even worse than this, idk

Hi all,

now i need to know

i) how to add encryption and decryption in any of routing-(DSDV,DSR,AODV,OLSR)?

ii) As of now in routing i am able to see only data flows, but is it possible to send some data(message) from source node and i want to retrieve(read) those messages from receiver nodes?

Since i am beginner, Quote:
i dont know whether my question is right or wrong?
Thanks

Question: How do I get this laptop to recognize this wireless chip. I know from prior research and experience this chip is optimal for this laptop (used it on winxp)

will encrypting my audio data and burning it on a cd/dvd be worth it since the other person can copy it onto there pc? such as audio files for court? I know it can be copied as long as the pc reads it. but can I protect or encrypt its data as not to be altered when copied? if it is possible please do tell thanks in advance.

Hi all,

I was wondering did anyone try running PEGASIS simulation on NS-2.34? I am using Ubuntu 10.04 and I tried running it with the LEACH+PEGASIS patch from exidus, but the pegasis output does not seem right, although the leach output seems fine.
As seen there is not data sent and the nodes alive stays 10 (used only 10 nodes) with energy still intact. Any input/thoughts are appreciated, thanks!

Booted my computer with 2 USB flash drives inserted. One of the drives turned out to be an MS-DOS boot drive. The PC booted in DOS and wiped out the partition table of the other flash drive with my data on it. This second (64Gb) drive had a single 64Gb type 83 (Linux) primary partition (ext4 file system).

Is there a way to recover the data that's on the second stick?

I've been told that all I have to do is repartition it exactly as it was and my data will be there. But I'd like to have advice from the pros here before I start messing with it.

For the time being, I dd-ed the entire stick, as is, onto a blank partition of my hard disk (dd if=/dev/sdb of=/dev/sda14). The process completed without errors but /dev/sda14 is unmountable for the moment.

Thanks for any help.
