General :: Limiting Concurrent FTP Connections - Less Than 10?

Feb 1, 2011

FTP servers I use frequently have imposed a simultaneous connections limit, usually 5-10 at the time. It was no problem under Windows, since Windows artificially limits allowed FTP connections to ~10 as far as I know. But it is a problem under Linux very much since I cannot find how to limit them :/ So far I used these clients: Native FTP client (Places -> Connect to FTP server). No apparent way to limit connections.

FileZilla. Under particular server settings you can limit number of simultaneous connections. Also you can do that globally in Edit -> Preferences -> Transfers. Problem is, it doesn't work, I still keep getting the 530 Sorry the maximum number of clients (10) for this user are already connected. And netstat shows quite a few simultaneous FileZilla connections no matter that I limited them to 1 both in global and local settings.

NCFTPPUT. 10 successful uploads and hi 530. Total Commander under Wine. Same. NetBeans IDE integrated ftp. Same. Some other crapy FTP clients which names I already forgot. Same. OS is Ubuntu 10.04 So, is there any way to force any of these FTP clients to use less than 10 concurrent connections?

Networking :: Max Number Of Concurrent TCP Connections

Feb 3, 2011

How do I find the maximum number of concurrent connections (in any state)? I'm running RHEL5 2.6.18-194.26.1.el5. Also, does tcp auto tune affect the number of concurrent connections or is it mostly used for dynamic buffer size allocation?

Server :: Apache Virtual Host To Limit The Concurrent Connections Of Virtual Hosts?

Jul 3, 2009

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.

General :: Best Windows For Two Concurrent Users?

Aug 3, 2010

I'm running Windows 7 in VMPlayer under Linux. I made some changes to Windows 7 to allow it to have two people logged in at the same time. However when I do this the sound lags behind on the host machine.

Is there a different version of Windows where I am less likely to have this problem?

General :: Encrypted Remote Filesystem With Concurrent Access - Is It Possible?

Jul 26, 2011

I'm looking for a way to store an encrypted filesystem on rsync.net which can be mounted and used by multiple clients concurrently - I've considered and experimented with many different ideas, including code...

but all of them are leading me to what looks like a fundamental theoretical problem: a filesystem with concurrent access needs someone to manage it, and who's going to manage it if I can't trust the server? Or refuse on principle to trust the server? There would need to be some trusted entity communicating with every client and making decisions to keep the filesystem and/or block device consistent, right?

Is my understanding correct, or is there any way of achieving what I'm trying to do?

I have a dual core processor and would really like to take full advantage from it. I'm pretty sure that only one core is being used when booting and I would like ti know if this is true for the rest of the laptop usage.Furthermore, I tried to follow a tutorial in order to edit/etc/init.d/rc*****Tutorial indicated that one could get the concurrency by changing the value CONCURRENCY=none to CONCURRENCY=shell however the file clearly says that "shell" is not a valid option, so I made no change

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??

Programming :: EPOLL Echo Server Not Concurrent?

Feb 16, 2011

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>

[Code]...

Security :: Policy That Limits Connections On Port - Encapsulates Total Sum Of All Connections From Hosts?

Jan 21, 2011

Is it fair to say that connLimit and hashlimit are very similiar on Linux i.e. while hashlimit caters to limits for groups of ports, they both set the connection rate limit per host? How in IPTables, do I configure a policy that limits connections on a port that encapsulates the total sum of all connections from all hosts? i.e. I do not want to allow more than 6000conn/minute for port range that is the sum of all connecting hosts?

General :: Sound Volume Increase Beyond 100%?

May 29, 2010

Some audio output from files or streams is too low. It is obvious that hardware is able to play the same sounds but louder but because of the data it just plays it at some low level even at 100% volume. Vlc can generally increase the volume of a file up to 200%. Is there a way to do the same thing VLC does system-wide and if possible for an arbitrary v percentage value.

If there is no application that does this, where should i look into for libs to do it myself or what code should i modify(eg code in the alsamixer)

Note: Asked the same thing on stackoverflow and they directed me here.

General :: Sounds Like Under 10% Of Speed Increase

May 16, 2011

I have an old AthlonXP-2600+ running at 2.078 Ghz which I was assured would do 2.6Ghz, but actually doesn't and 2.178 Ghz is what we settled on. I have 266mhz ram on a board with 333mhz FSB and we sorted that out also, and specified the ram speed. That sounds like under 10% of a speed increase, if any. But the previous kernel I built here took 55 minutes (time make -j4). The one I built after the mods (nearly same config) took 33 minutes. (make clean; time make -j4) 40%? I've clearly improved or fixed something.

General :: Increase Size Of '/' In Ubuntu?

Feb 12, 2011

Finally i have installed ubuntu 10.10 on my home PC. Its working so so good i cant really imagine :-). At the time of partition due to my immaturity, i selected the size of '/' to be 10 Gb. Now i want to increase it without reinstalling ubuntu. Is there any safe way of doing it ? i did some research and came to know that Gparted might be of some help, but i will really be grateful if any of you can guide me.

the use of livecd for example, can i use liveusb instead ? i was thinking of making liveusb of centos 5.5.

Currently i have 3 partitions

'/' 10 GB
'/boot' 99 MB
'Date' 50 GB

on rest, its my windows xp.
