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.
I was looking at this file that was padded with 0's in hexdump. I noticed the 0's were escaped so they would be literal 0's. Why is this?
View 1 Replies View RelatedI am not clear with difference between hexdump and objdump and coredump. I wrote a small program
Code:
main (){
int a=2;
int b=4;
int k=b/a;
int m=9;

Some of the above instructions such as 89 d0 should be present in hexdump. What exactly is the hexdump ,objdump and coredump and what is their importance?
recently I'm working with one of these... LM-PC001
it works via /dev/input/event4, so I'm using devinput driver for lirc, the thing is, it works flawlessy when lirc is not running, (via linux-input-layer) but I do need to make it work with lirc...
I can make work almost everything using this lircd.conf (incomplete here)
Code:
# Please make this file available to others
# by sending it to <lirc@bartelmus.de>
#
# this config file was automatically generated
[Code]...
First thing, it doesn't show the header (not a problem really) but as you can see the bits that differ the direction on the axis is the latter ones, and lirc is not taking them into account so both buttons result in the same direction...
Is there a way that i can make lirc take them into account?
also irrecord doesn't work because of the "0x40004" header, all comands, are detected as "0x400004"...
and since it uses devinput driver, mode2 says "This program doesn't work for this hardware yet."
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.

View 9 Replies View RelatedI wanted to show a track from a CD to a friend who uses Windows. I tried to rip it in MP3 (LAME) format, because I couldn't remember whether Windows Media Player can read OGG or FLAC (whatever that is) format. Due to some kind of error (no explanation given other than "command failed"), my K3B would not rip in MP3. Which of the formats can Windows Media Player read? I know it can read WAV, but that's inconveniently large to send by e-mail or over an instant messenger.

View 3 Replies View RelatedI've inherited the following Virtual Machine scenario and am new to Linux Administration and Patch Management. The Host Operating System is Windows 2003 Enterprise, which has VMware Server 2.0.2 installed. Under the VMware Server 2.0.2 I have a Ubuntu 32-bit OS web server running Apache2 Web Services. When I log onto the Ubuntu server (9.10 32-bit) I see the following two lines just above the new mail/last logon lines.
85 packages can be updated
55 updates are security updates
I would like to see at least a summary of each update and its urgency so I can notify the various developers/server owners to get their input regarding whether we should or should not apply that particular update to the server. We apply the patches in our test/dev environment first then once vetted there we roll them out to our production servers. What I am looking for is a way to automate the gathering of the information and once approval has been received automating the actual patching process so that I do not have to manually perform the apt-get process for each separate package needed/approved.
Ideally I would like a recommendation for a GUI based package to manage this process and that is capable of generating the appropriate reports for the 'powers that be' regarding the current security/patch management environment. For proof of concept I would like a free version that is not hamstrung in functionality but is not too costly to procure the production version with no limitations.

I put an additional cooling fan in front of the air intake and the computer is staying on but now will not open the emails in the my hot mail account. It seems to open the account, I can see what is in my in box just can not open them. Moving the curser over the unopened email usually made what is in task bar at the bottom of the page change. As of now it continues to say "Done" in stead of showing a task. Moving the curser over other things on the same page will make the task bar say "javascript" only.

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.)
