I backed up my 320GB hard drive to a file with dd:
Code:
dd if=/dev/sda of=dev_sda.17-Mar-2012 bs=1048576
The main idea was to be able to be able to completely replace my hard drive from this backup if necessary, but I'd also like to be able to restore individual files. I realize I could use this dd technique to backup each partition separately (there are six partitions on there), and then use the loopback device to mount those individual files, but I'd like to just have a single backup of the entire disk that can be used to both replace the disk and to restore individual files.
So, I'm imagining making this file available as some new device file, say, /dev/sdax, and then seeing /dev/sdax1, /dev/sdax5, /dev/sdax6, etc, and then being able to mount each of those. Or, how else can I get at the individual files in that 320GB backup file?
Hi,
I was wondering if any of you guys know of way to make applications that use sound device on linux to access it in a "non-exclusive manner", the aim is to be able to use more than one application that requires the sound device.
Thanks (0 Replies)

Hello everyone,
I write a program (Linux & Solaris) that will run as non-root user, but the program must have rw access to a device /dev/ipmi (on linux) or /dev/bmc (on solaris).
What is the standard way of granting such access?
Linux:
chmod on /dev/ipmi ?
suid root my program?

In this part of the assignment, delegates will create a pseudo-device and write a device driver for it. The pseudo-device provides a “backdoor” for gaining root access for a particular user. Instead of compiling the device driver into the kernel, delegate will create a module.... (1 Reply)

proto(4) Kernel Interfaces Manual proto(4)NAME
proto - prototype job file for at
SYNOPSIS DESCRIPTION
When a job is submitted to or the job is constructed as a POSIX shell script (see at(1)). The job file is created in as follows:
o creates a header describing the job as an job or a job. jobs submitted to all queues other than queue are listed as jobs. The header
is:
for an job, or
for a job.
o A set of POSIX shell commands is added to make the environment (see environ(5)) for the job the same as the current environment.
o then copies text from the prototype file to the job file, except for special variables that are replaced by other text:
Replaced by the current working directory.
Replaced by the current file size limit (see
ulimit(2)).
Replaced by the current umask (see
umask(2)).
Replaced by the time at which the job should be run,
expressed as seconds since January 1, 1970, 00:00 Coordinated Universal Time, preceded by a colon.
Replaced by text read by
from the standard input (that is, the commands provided to to be run in the job).
o When a job is submitted to queue queue, uses the file as the prototype file if it exists. Otherwise, it uses the file
EXAMPLES
The following file creates commands to change the current directory, file size limit, and umask in the job to their respective values as
they existed when was originally run. These commands are inserted before the commands in the job:
