View 1 Replies View RelatedI 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?
I have a server installed with a Fedora 8 and the other client PC were installed with Windows XP.

I found that the .EXE (application file) :were unable to be opened in all of the clients and also the server. How can I solve this problem?
View 7 Replies View RelatedI 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?

View 2 Replies View Relatedit's the installation media or the ISO is broken because i have reburned / redownloaded the fedora14 multiple times with the same result. I even tried burning the disc on a different computer just to make sure the burner is still working. This is the error i am getting when the "Starting installation Process" dialog displayed.
"The file upstart-sysvint.0.65.9.fc14.i686.rpm cannot be opened. This is due to a missing file, a corrupt package or corrupt media. Please verify your installation source" I remember fedora 13 and below i have to use nousb command or something similar to get fedora installed properly but not for fedora 14. It just pops up with the message above.

View 1 Replies View RelatedIs 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 RelatedThis 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?

I want to track the number of requests that a file gets downloaded and viewed.
What I have is mp4 files on the server and they could either get played in flash player or downloaded via mobile or whatever.
I need to see how many times that files gets downloaded or viewed. Since its in a php page I am able to track the number of views. But I want to able to track the direct downloads.
I was thinking something along the lines of htaccess redirect to php then to file.
But that would mess up the player from playing the file I would think. I am not sure how to make that happen with the htaccess either though.
I have this wma file that I want to play and I looked around and found alot of ways to make this happen. However, none has work for me. But first let me explain my problem. I have these wma files that just wont work but they worked once before. Now when I try to open the files all I get is some message that the file can not be opened. I have done many efforts to make it work including things like medibuntu. BTW, there was this once moment that when I tried to open the file it PLAYED! but then after it did not open.

-The Mkv video file cannot be opened by the Mplayer due to something that I don't know. I try to open it via the gnome-terminal and end up with something like this:
The, I try to play it with VLC media player. Everthing seems fine but after few minutes, I can see the lagging of the video and distractions on the screen.
Then, I've open my Windows 7 and play the mkv files with the KMplayer, everything is fine. No lagging, no distractions.
I've already updated the ubuntu-restricted-extras. I've already installed the libxine1-ffmpeg and nothings good appeared.
I've already installed the mkvtoolnix-gui (which is i don't know what is it) but similar prob appear.
how did play mkv files? With no lags or disctractions?

My program need to monitor the foler to know which file under the folder is being opened/created for writing. I add the folder into watch list using inotify_add_watch, when a file -- say 'AA' -- is created, I'll get the event through read api call. But the inotify_event only have file name 'AA' and a event mask. these parameters can't help me to know how the 'AA' is created/openned. So I have to scan the /proc folder to get to know how is 'AA' created/openned. I don't think this is a efficient way, especially if there are lots of files are openned/created in a short time span.

Whenever I edit a spreadsheet in Gnumeric, I have to have an argument about saving the edited version. First, it says it wants to save it in Gnumeric's XML format instead of whatever format I opened it in, and then I get a dialog warning me the file already exists,is it OK to overwrite it? All my spreadsheets are either .odt or .csv. I just want to be able to open, edit and save without an argument every time. It's like telling a child that it's bed time and having the same argument every night, and it's getting on my nerves.Is there a setting where I can get gnumeric to obediently save the edited version, or do I just have to put up with the slower opening times of LibreOffice instead?
