Apr 22, 2010I just noticed that one of my blade server has such a abnormal running status.Historically, the three values in file-nr denoted the number of allocated file handles, the number of allocated but unused file handles, and the maximum number of file handles.But it's really strange to see low value for the first column.

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?

View 2 Replies View RelatedGeneral :: Fork Behavior While Copying File Descriptors
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".

Programming :: 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?

Server :: Use System Monitor Via A VNC Connection The Free Disk Space Value Is 20GB Free On The Same Volume
May 18, 2011I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.

Code:

((8115292-87680-1444676)*100/8115292) => 81%
As per the above calculation 81% of memory is used.Is this correct? and if so Am I running out of memory?what is the limit in % that I should maintain for a better performance?

Ubuntu :: Create Text File Which Lists Sales - Bash Script Shows Total Sales Of Each Month?
Mar 8, 2011Firstly i'd like to introduce myself before I ask my question, i am currently studying a "Network Operating System 2" course, and in the syllabus the professor decided to use Ubuntu Linux for us. This is a first for me and I am truly greatly interested in the OS. It seems like a solid system once you get to know the deep foundations of it. The professor has already given us an assignment, but I feel its not fair as its just a bit too much from out of what he taught us .. He did not teach us what he is asking for. He asked us to create to a text file which lists the Sales from two Salespersons, and each one will have an amount for each month .. So 12 entries for each salesperson.
Using that text file, we should write a bash script which would read the values from the above text file, and produce a "Monthly Sales" text file, which shows the total sales of each month (combined from both the salespersons). I would like to ask for some guidance, some help on how to start. It's just that he didn't teach us any commands about this matter.

All I want is a simple way so my frien and I can play chess over the net. So I looked at php scripts. Nothing suitable, that I could find. I'd like a nice web interface. My thought figure out how to "talk" to gnuchess or whatever an write some php to talk to it. Xboard, html style. (Is there one?) Or run my own private chess server.
