View 1 Replies View RelatedSoftware :: No Standard File Descriptors For Init
Jan 10, 2011I have a weird problem with one of my servers. When system is booted and right before I should se "INIT 2.86 starting..." message, all the messages disappear. Only kernel messages get logged to console and later login prompt, but nothing in betweek (there are 20+ services starting successfully, just without emitting a single character).I checked /proc/PID/fd of the boot script (in my case called /etc/rc.d/rc.boot but that does not matter).
The only significant difference in hardware to other servers is that this one runs RV350 AP [Radeon 9600] graphic card.Now, my question is: where could those FDs go or why are they not opened?Does anyone have a clue about this, or a hint?

Jun 17, 2010I am quite confused about the following description on fork. Could you please explain it ?The child process shall have its own copy of the parent's file descriptors. Each of the child's file descriptors shall refer to the same open file description with the corresponding file descriptor of the parent.For example, I am opening a socket and then fork. Now, does the child have a separate socket or is shares it with the parent. Does I have any impact on using it in child?

Feb 23, 2011Is there already a program that reads multiple pipes or file descriptors and writes to the standard output (not splitting lines).Like cat, but reading all files simultaneously and preserving lines.It is needed to avoid coding of select/epoll loops or using multithreading in simple programs. Like "select loop for bash".

May 1, 2010This for Kernel 2.6.29.6. I'm trying to code a kernel module that displays process information.
how to count opened file descriptors per task. I have been able to write a module that lists all the current process names along with their pid number in /var/log/messages. Basically, I cycle through the ring of processes using the macro for_each_process(task) and printk the comm and pid of each task. I'm trying to see how many file descriptors each task has open. I've been reading up in books and all over the internet. At first I thought I needed to access max_fds under files_struct, but that just lists the maximum number of file descriptors that can be opened per task, which by default is set at 256. I then thought about counting the elements in the fd_array. But then I learned that every task's fd_array is initially set at 32. Now I know that I need to access open_fds of type fd_set * in files_struct. open_fds is a pointer to all the open file descriptors. The problem is that I don't know how to access a pointer of type fd_set.
Is there a good guide or book that really focuses on type fd_set and open_fds? Every book and resource I've read never really go into depth on this. relationship between files struct, open_fds, and the open file descriptors in task?

Jul 25, 2010I downloaded three iso-images, 1 dvd-image and 2 cd-images:
openSUSE-11.3-DVD-i586.iso
openSUSE-11.3-GNOME-LiveCD-i686.iso
openSUSE-11.3-KDE4-LiveCD-i686.iso
Being paranoid, I created iso-files from the burnt DVD-R and the two burnt CD-R to verify integrity.
The iso-file of the DVD-R was identical to the downloaded image. Both iso-files created from the CD-R were different in size.
The original size of openSUSE-11.3-KDE4-LiveCD-i686.iso is 719.323.136 Bytes.
I only got 718.938.112 Bytes when recreating an ISO-file from my CD-R.
The CD-R is from Sony. When the length of my ISO-file doesn't correspond to the downloaded one, the checksum file verification doesn't work.

Ubuntu :: Pdftk Output File With Pages Extracts Same Size As Input File?
Apr 22, 2011I am curious if perhaps I am doing something wrong extracting pages from a pdf doc using pdftk and creating a new file. I am only extracting the odd pages from the file and outputting them to a new file that is now only 20 pages instead of the input's 40 pages, yet the new output file is still 1.4Mb in size, the same as the original.
It seems strange to extract only half the pages of a large document and end up with a result that is the same size. how to streamline the resulting pdf's using pdftk?
BTW this is the command I am using, in case perhaps I am missing an option to optimize file size or something:
Code:
pdftk A=ch15.pdf cat A1-40odd output odd.pdf
