Server :: Concurrent File Read Limit
Jul 12, 2011
More of a "Knowledge" question... Is their a limit to the number of reads a single file can take? Say for example I have a file named config.xml in an htdocs directory and a XMLReader function from PHP reads some value(s) out of this file for every connection of Apache or NGinx. Now suppose my site receives a gigantic spike in traffic (but Apache stays opertational through it all)... Is their a point at which the underlying system would simply not be able to open+read config.xml anymore??

apache virtual host to limit the concurrent connections of virtual hosts? Taking into account the host of each virtual user's home directory can also have more than one subdirectory, which should be restricted to a subdirectory. Is beyond the control of the operation of these sites in a subdirectory. Best local restrictions or limitations to the overall situation.

I have a problem with open file limit. The software I'm installing claims "Open file limit (ulimit -H -n) too low (1014), need at least 6311" but when I check the linit I get the following

I have a VPS server with 512 MB memory. The php.ini is set so script memory limit = 16 MB. However, I have noticed in my top report, instances like the following:
Quote:
5484 coldclim 25 0 46476 32m 5920 R 0.0 6.4 0:00.93 php
The bold number of 6.4 is the % of sever memory this process is using. 6.4 % of 512 MB of memory is about 32 MB of memory, so it appears that this isn't being limited by php.ini. Am I correct? This leads to the next question: Is there some way to limit the amount of memory a single suphp process can use? (Basically, something like the setting in php.ini which limits suphp processes in the same way.)

I am working on an epoll version of an echoserver that I am porting from a multithreaded version I wrote.What it should do: The server should get a connection from a client > say x client connected > print x message from said client. What it is doing: The server looks like it is only accepting one connection at a time, and any other clients are queued. When the queue is empty it looks like the program is aborting with a SIGABRT. EDIT:// fixed the program exiting in the close function. Still one client at a time
Code:
#include <assert.h>
#include <errno.h>
#include <fcntl.h>
#include <netinet/in.h>
#include <stdio.h>
#include <stdlib.h>

I have a videos server here at work running Mandriva 2009 Spring and I need to copy a 10 gig file from it to a USB drive. The drive needs to be readable and writable from Windows. The file size rules out FAT, and when I try to write to it when formatted as NTFS I get an error about it being a read-only file system. How can I get NTFS support up and running?

For my project, it's absolutely necessary to have a read-only root partition system. I have a writable /opt/project partition.But, I also need to start x server. startx This tries to write to some temporary files and fails as / is readonly. Is there any how-to on how to move this temporary files to the writable portions of the file system.

I've been a Xubuntu/Ubuntu/Lubuntu hobby user for about 18 months now. I started using Linux as a way to revive older computers provide a backup and expand my knowledge of computing. The command line was something new to me but as long as I can find detailed directions on how to do what I want I can usually manage. I set up a Samba server for my home shared network and now I'd like to make the shared drives of that server accessible from outside my network. Via ssh or ftp or some program of the like. I'd like to have it user name and password protected. Configurable user rights would be nice. (read/write/delete/etc) As well as novice user friendly.
My end goal is a server with read/write capability that I will be able to access from work or a friends house or anywhere with an Internet connection and my laptop. I understand about port forwarding and have done so with my home network behind an AT&T U-verse router/modem. I've researched openssh and some ftp setups but they seem like they can be difficult. Now for the questions. Is this task something that can be accomplished without a degree in computer networking? Is there a program(s) that would make this a simpler task? Is this more complex than its worth? How would I go about setting up such a thing?

I currently have a debian hpc server unit of 10 p4 computers running under debian lenny in use for serving my home network via pxe. I was wondering if there was anything I could use to allow the same read and write acces that is on my pxe machines on my new palm pre plus. That would save me the hassle of syncing all my documents and movies etc to my phone every day or so.
So basically what I am asking is if I can use the current 5tb nfs raid and mount it some way to a remote ip that I can access fully on my phone without the need for a flash plugin. Btw the phone is homebrew app ready.

I was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??

I have a large file (deflated size: 602191947)that is not saved in my Ubuntu One account. On sync'ing the file is being uploaded, and eventually reaches 602191947 - and then nothing more happens to this file - but sync'ing the following files in the queue goes on with success. I have tried manual upload with the same result. The file is still being marked as 'uploading' even after several tries and log ins/log outs, and reboots. So I was just wondering whether there is a file size limit - can't seem to find information regarding this.

a possibly preposterous question. I am aware that you can designate a swap file or swap partition on your hard drive that linux uses as "memory". Suggested sizes for the swap file that I've seen range up to about 1024MB. Is there a limit to the swap file size that you can set?Basically I am running a perl script that processes a massive B) file (DNA sequence data), etc, and requires around 48 GB of memory to run, maybe a bit less. So, would it be possible to set a swap file to a massive, ridiculous size (~60GB oratever) and successfully run such a script on a desktop?Yes, I am aware that it would massively ow down the process. The thing is, if the perl script normally completes in about half an hour, and I can get it working on a desktop, I don't mind if it takes days or weeks to complete. I really don't. That's because it takes days or weeks to get access to a computer with the required grunt to do it.So, is this a stupid idea? Is it even possible? If so, given a perl script that normally completes in a half hour on a 48G system, if you do this, would it take days? weeks? decades
