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".
View 1 Replies View RelatedProgramming :: Kernel Module - Task_struct / Files Struct, Open_fds, And The Open File Descriptors In Task?
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?

View 5 Replies View RelatedUbuntu :: Set File Roller As Default Archive App?
Mar 10, 2010I was messing with Openbox, LXDE, and Pekwm a couple days ago to see if I liked any of them, but I ended up coming back to gnome.
But it seems that, somehow, some of my preferred apps settings got wiped during this process.
The most annoying one, is I have no default application for archives (zip, tar.gz, etc). I can tell Ubuntu to "Open With..." and that works... but it doesn't stick.
How can I return this back to normal Ubuntu behavior?
UPDATE: It appears that nearly ALL my preferred application settings are gone. Pretty much everything except couple filetypes show up with the standard "file" icon and won't open unless I use "open with".
Ubuntu :: Restore Default Kde File Associations?
Jun 7, 2010i initially installed ubuntu, working with gnome for a while. i now migrated to kde as i like it better. however, the kde session still has lots of the "old" file associations set as they are in gnome...
some examples? text files open in gedit, instead of kate pdfs open in "document viewer" instead of okular double clicking zip folder opens the "archiver" (gnome?), extracting an archive from the archiver and then pressing the "open folder" dialog after extracting has finished, opens nautilus (although dophin is the default program for inodes). etc.
i'm aware of the possibility to edit file associations, however thats a tedious thingy to do, if you want to get it complete... furthermore, the file association edit dialog has the "defaults" button disabled, hence my questions:
is there any way to "restore" the kde default file associations, just as i would have installed kubuntu initially? i don't want to reinstall just because of this.
Ubuntu :: How To Edit The /etc/default/grub File

Ubuntu :: Setting Default File Permissions
Jun 26, 2011I have a file server running a cronjob to reset file permissions on a regular basis. I was thinking, I wonder if there is a way to do the chmod and chown command in a single command, as I always have to do both on the same folder, the way that you can do "chown root:users Uploads" instead of having to do two separate commands for chown and chgrp.
Then I got to thinking, are these commands even necessary? Every file copied or moved into these folders by any user needs to be something like "chmod 750" and "chgrp root:users", so rather than running a cronjob to do these modifications at regular intervals, there ought to be a way to set the folder permissions so that any files contained within will have these permissions.
The problem arises because users create documents, then a supervisor with elevated privileges can move those documents into a shared folder, however the permissions are wrong, they are user1:user1 for the owner and group and the other users can't read the file until a cronjob changes the group to be users. This has actually been acceptable, but certainly there is a better way to do this.
Ubuntu :: Change Default File Permissions?
Jul 3, 2011my dad has been using Ubuntu for a few weeks now and likes it, however he's having some issues regarding read-only files. He's a doctor and frequently has to download word files to edit, however they always download as a read-only file. While this isn't particularly difficult to do, he finds doing it tiresome and because he isn't the most proficient PC user, may have difficulty with it when I return to school after the summer. I was hoping that there's some way to change the default settings so that all files downloaded are writeable.
Additionally, he has a number CD-RWs which he both retrieves files from and stores them to, however when trying to access these CDs he is told that they are read-only. Right clicking on the CD and trying to change the access permissions doesn't work (says that permissions can't be changed because the disc is read-only).
General :: Set Krusader As Default File Manager ?
Mar 7, 2010I'm trying to set krusader as my default file manager. I have gone into System Settings > Default Applications > File Manager and changed Dolphin to Krusader.
When I plug in a flash card the Device Notifier pops up and I click on the device inserted. The choices I get are Digikam, Dolphin, and Do Nothing.
I click on "Dolphin" (hard coded it appears) and it looks like Krusader tries to start. I get the cursor with the bouncing krusader mini-icon and an entry in the panel, but then nothing happens. It all goes away and I'm left with a blank screen (wallpaper, actually).
I've chosen Krusader from the menu, so presumably the arguments to it are good. I have KDE 4.3.3 and krusader 2.0.0.
Debian :: Set Default Application For Specific File Extensions
Dec 17, 2015How to properly set some entries in:
$HOME/.config/mimeapps.list
so that:
*.odb files are opened by default with libreoffice base
*.org files (just org files not plain text files) are opened by default with emacs
For some reason I can not figure out how to proceed.
As far as I know - i.e. for what I have been reading in the documentation - the default application for a given MIME-type is specified by writing into the group [Default Applications] in the mimeapps.list file
My configuration is the following:
- 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64 GNU/Linux
- gnome desktop

May 25, 2011How do I change the default file associations in F15/gnome 3? My system is currently set to open .tex files with emacs. But I prefer TeXworks, and while TeXworks shows up in the "Open With" menu, it would be convenient if double-clicking on a tex file opened it in TeXworks. In gnome2, the "Open with-->Other application" option let me select the default program associated with a particular type of file, but this functionality seems to be gone in Gnome 3. Do I have to edit some config file?
