According to blktrace manual, such a number of 18752478 is known as a "starting block", followed by the size of request. If I understand correctly, sdb5 is in the range of blocks from 9373897 to 9373896+9373897-1=18747792. However, blktrace's output shows that a R request occurs on a block whose index is much larger than the range of the partition.
How should I understand correctly the value of 18752478?
I am using kernel 2.6.29 on my embedded device, and enabled config option Support for tracing block io actions after compiling kernel making its zImage (for porting to device) the folder block compiled all files of blktrace and created .o files....

I have recently set up a new site, and I find recently the host is not quite responding to request when I ssh to the host or just hit my site's url. I think I could be under some kind of DoS attack, because I do not think google's crawling can cause that problem. Is there any way I can figure out who is doing that? I am not quite expert for apache, and I just barely know how to install it.

how long mkfs will take to check for bad blocks on an 500 gig SATA drive? The drive is a warranty replacement from Western Digital. It's been running about an hour now. I had run mkfs ext3 on it before I realized I should check for bad blocks so I am running the check now.
I'm running vsftpd on a Ubuntu 10.4 server and noticed that my ftp server is getting brute force attacked. I usually check for the IP address and manually add it to my Smoothwall firewall but I was wondering if there is a way for vsftpd to automatically block denied access after certain number of attempts. Let's say 5.

I installed OS11.4 on my old laptop, Compaq Armada E500., 512MB RAM, ATI Rage Mobility. During installation I chose "minimal server" and added some development packages, lxde and a little more. I chose to start in runlevel 3 which is full networking without X. Still, when computer is booted it tries to start Xorg which doesn't work because of some problem w driver. The start-up seems to stop there, it never loads completely - seems most things in runlevel 3 are not started (see below) I can manually login on laptop and fix it - but never permanently, same thing again after reboot.
I have checked /etc/inittab & yast - both states default runlevel is 3. I have checked services to be started both directly, browsing directory /etc/rc.d/rc3.d/, and with YaST, it is very clear X should not load during boot. But, as said, it does.. I don't really care about the driver problem right now, I can fix that later when I have more time. So how do I stop X from getting started automatically?
More info, if needed: The installation also stopped with message on tty1 "Starting YaST2" and tty8 showing errors with graphics driver (mach64). The system seemed to be installed though, so I simply rebooted (issuing "reboot" from tty2).
[Code]....
I'm not completely sure where it stops, network is configured but keyboard is wrong and mysql & everything after is not started, so somewhere between S02network and S06kbd. I'm going to use it as a server for testing purposes so no X is actually needed - however I do want to have X & lxde installed just in case, my Internet connection at home is terribly slow so I need most things I might need in the future installed today.

I want to test LVM+Raid. When I was testing ZFS on Solaris, I was able to create regular files, and use those as disks for testing.I tried creating a regular file full of zeros w/ dd, then partitioning that. fdisk seemed to be able to create a partition on the regular file, but mkfs and parted couldn't work with it. Is there any way to create fake block devices for testing?

I'm trying trying to understand dd, and I'd like to know why frequently do we have to use a block read/write size, like "dd bs=1024", "dd ibs=512"... If it executes the operation byte by byte, isn't it irrelevant? What is this block size then?
