General :: "written Data In Track 1 Differs From Original"
Mar 3, 2011
I just tried to burn an ISO to a CD-R in K3B, and it finished with the message "written data in track 1 differs from original." I get that a lot; until now, I blamed it on my failing CD drives . What can I do to avoid it besides burning at a slow speed? I know that, having heard years ago that I should burn at 4x; but my new DVD-RW burner's slowest writing speed is 16x. (I'm annoyed at that. It was a Christmas gift, and I didn't think of specifying a write speed. I wouldn't be surprised if new CD drives can't burn at such a slow speed, though.)

I went and fdisk'd a USB disk and put the Fat32 filesystem onto it. Then I thought I ran dosfsck over it which I thort formatted the disk - apparently not. Then I copied a bunch of files and directories to it. Now I am unable to recover the files and data. In the rare instances when I perform a sloppy mount I see directories named 001, 002, 003 and 004. These directories variously contain files named 001, 002, 004 (no 003) etc.
Fdisk gives me:
I don't know enough to use dd, kpartx, parted, partmon, partprobe, partx et al

I was just reading about the whole boot process on computers and am curious as to why the BIOS can only read and execute code and data from only cylinder 0, track 0 and sector 1 of the disk being booted from? Why can't the BIOS read from any other disk location?

I know there's a command to display the live amounts of data being written and read to the disk.Like, it tells you how many blocks have been read/written so far to a device

I'm sure this is simple but I haven't a clue how to do it other than System Monitor, which only displays for the total uptime.
I want to see what my total network data use is in Bytes (GB, MB, or KB) downloaded/uploaded for the month or any given date range.
Rationale is I want to use wireless tethering from my phone to replace my broadband connection at home. At the moment my phone contract gives me unlimited data access, however if I were to sign a new contract today this would drop to 2 GB a month with hefty overage charges.

I have a fully up-to-dateCentOS 5.6. As of some very recent package update (later than May 12), sound-juicer is unable to retrieve track data for any disc; it just reports "Unknown Title" and "Unknown Artist".
Unfortunately I do not know how to tell which particular package it was, or even how to get a list of recently-updated packages.
Tracks are still extracted fine, it's just the musicbrainz connection which is doa.
I'd be happy to try an alternative program with musicbrainz capability, but couldn't find any. The installed k3b doesn't have any ripping options in the tools menu, where I gather it's supposed to be.

the data usage information from the carrier is often several hours old and is accessed in some arcane ways (logging into their website, sending a specific SMS message at best). Here's my idea: single-session data usage is perfectly reported by ifconfig ppp0. The problem is, how tokeep track of previous sessions accumulate the numbers rollover to zero at specified date To be able to do this across computers means that one needs to store it on the modem/SIM card itself. (As a specially crafted SMS message, or a contact).

i'm wondering if it's possible to restore the original image file that you have hidden data in with steghide. The basic Idea is you have a photo using gpg sign it and then embed the signature. then remove the signature at a later time and check it with the signature. I hope another "inverse" algorithm doesn't need to be written to undo the first (if a "inverse algorithm is possible). This assume you already have the pass phrase or that there is no pass phrase. I already know how to retrieve the original file just want to remove the hidden data from the Image and restore it's attributes.

I'm using Ubuntu 10.04 and a Sony H-5 dig. camera. Downloaded 700 photos using F-Spot and they're all visible but unable to get the individual photo jpeg data?
1. How do you get the "original camera data" that is attached to each photo jpeg? I must be missing a plug-in? Or?
2. Not possible to right click and copy these photo's out of F-Spot into a new folder?

I was attempting to get crontab to kick off a daily job, but the job wont start. I opened /var/log/messages and noticed all the logs were from 6 months ago. I cleared the log and then did a tail -f so I could watch it for activity. I then hit my box with anunsuccessful log in attempt. Nothing happened to the log. The uptime of my box is 22 days and the logs that were in it before I cleared it were from months ago.Is there a daemon I can check or another file I can mod to get logs writing again?

with reference to my this thread: [URL]
After installing Windows 7, the GRUB got re-written by the windows bootloader. Now after booting into the live cd and mounting /boot partition (sda2), I tried to reinstall the GRUB with this command grub-install --root-directory=/mnt /dev/sda as told by this [URL]
But I got the an error which says, Are you sure /dev is mounted? then i tried the same command on the / partition (sda5) which said, cannot find boot directory, Are you sure /dev is mounted?
And installation failed, now after restarting its just a black screen with grub> prompt.

I am capturing the same traffic both on client and server. Using Microsoft Network Monitor on client and tcpdump on Linux server.
And when comparing the content of one specific frame captured on two machines, I see it different!
Precisely:
I have SIP communicator on client and opensips on server. Client is doing a REGISTER request to the server. This request contains "Contact:" header, which should contain an IP address of the machine.
When capturend on client, this header contains local private IP address of a machine with SIP communicator (which is 192.168.***). But when captured on server, this header contains the outer address of my provider's router.
I have 2 possible explanations:
1) Some unknown agent acting between my client and server
2) opensips itself is acting at a so low level, that the result of it's frame manipulation is visible by tcpdump.
I am interested if the second option is possible? opensips is a proxy, so does proxy able to manipulate frames directly in the medium?
If so, the is it possible to run tcpdump at a lower level, so that it see packets before opensips processing?

it is about the program sha1sum to create SHA1-hashes. As you probably know, SHA1-Hashes do have the length 20 byte. So when I just type:
Code:
sha1sum myfile
it produces an output of
Code:
(some20byte) myfile
just as it should. Now I want to store the 20byte hash in another file, I use this command:
Code:
sha1sum myfile | awk "{print $1}" >> myhash
Unfortunately I'm not familiar with awk, but this should cut off the end of the sha1sum output, which is the name of the file again. The problem here is: The newly created file myhash has the size 41 bytes, and printing it out I can see that it is not the original hash (I wrote a little program to print it bytewise).

Here is what I am doing I have a file, a.txt for example, with following contents:
Code:
coreutils install
cpio install
cpp install
cpp-4.3 install
dbus install
[Code]...
So it seems like the sorting algo. for dpkg --get-selections is different than sorting algo. of 'sort' command when it encounters "-" (hyphen). How can I sort the original file (a.txt) in such a way that it produces the output file ,b.txt, exactly the same.

Perhaps somebody knows this one:
When I mount my external usb-drive within KDE it's mounted on /media/disk.
When I mount my external usb-drive (yes, the same one) within LXDE it's mounted on /media/72F580136411D534.
Not a great deal, but when I use DirSyncPro to backup some stuff I have to make adjustments to my saved settings, e.g. change the target folders.

I'm setting the hardware clock on RHEL 5.1 system using /sbin/hwclock --systohc. After setting the clock I issue a date command followed by a /sbin/hwclock --show from within a script to get fast resolution and I see that the hardware clock precedes the system time on average by .5 seconds. I would think the clock should be identical after setting.

How would i do a hexdump in Ubuntu for the first track of a HDD? I am looking for a winhex-esque output if that makes sense. The first track has 63 sectors, each 512 bytes long. I tried
dd if=/dev/sda bs=1 count=512 | hexdump -C
but that only gave me what appears to be the MBR, or first sector of the HDD.

Last day i have faced an attack on Apache/2.2.14 (Ubuntu).A user shoots 53 hits within 20 seconds from same IP and as a result db connections to MySQL increased.
a.) Is there any way in Apache to block these type of requests
b.) how can we trace when this type of attack happened to Apache.
Also I have noticed an entry in Apache error log during attack period

Possible Duplicate: time tracking application on linux Every Linux time-tracking application I've seen assumes you're tracking time for projects, perhaps to create invoices later for your clients. This is not what I'm looking for. Rather, I just want some insight into how I spend my time on my computer. I'd like to waste less time on my computer, and spend my time on more productive tasks. The first step to improving anything is to measure it. But I can't be bothered or remember to click on some icon and switch "projects" every time I change from my terminal to browsing ....., or something like that. I want the time I spend on different applications tracked automatically.
