I upload picture files to an ftp server. I can't do much about my upload speed but I think that a multi-thread upload may yield the same kind of improvements that a multi-thread download yields.
View 4 RepliesAnyone know of a good download manager for ubuntu that will support multi thread as well as site logins. I do a lot of downloading from rapid share and all the download managers i've tried don't support site logins.

View 2 Replies View RelatedI'm trying to create a separate thread for my program which basically polls using the read command. However this new thread seems to block the main thread, anyone know why this could happen.
In main I call this function pthread_create(&mainEventThread, NULL, GenericEventThread, NULL);
which calls
/*New threads start function */
void *GenericEventThread()
{
short int i, nError = -1;
[Code]...
I've used pthread_self to check that a new thread is being created, so why is the while loop in one thread blocking the main thread from running, I haven't used the join function anywhere in my code.
I am going to use "pthread_setaffinity_np" to bind a thread to a specific core. My application has two threads. I have used mutex to assign a specific id to each thread and then bind that thread to a core different from another core. but it seems that the os assigns both thread to one core.What should I do to bind each thread to a specific core?
View 4 Replies View RelatedI wrote a program that multiplies 2 matrices using multi-threads and another one using multiple processes and shared memory. Both in C.I need to find the total memory usage of these programs. I know of the top command, but when my matrices are relatively small they don't even show up on top because they complete so fast, how can I find the memory usage for these instances?Also, how can I find the total turnaround time of my programs
View 1 Replies View RelatedI have an ATI Radeon HD 3300 on-board video chipset, and an ATI Radeon HD 4350 PCI card. What I want is to have both displays available from one mouse/keyboard. I want to play media on one and have the other as my main desktop.The problem is that with Xinerama enabled, KDE desktop effects do not work (KDE says XComposite and XDamage are not available, even though I explicitly enabled them as extensions in the xorg.conf file), and performance is quite bad. Without Xinerama enabled, performance is great, desktop effects work great, but there's a lot of trouble with full-screen video, and the KWin window manager does not apply in the second display (although I can run a second instance of KWin on :0.1).
View 2 Replies View RelatedAnyone successfully using VNC client on a Mac to control a Debian server?I have the vncserver setup on the Debian machine properly. But I'm having problems connecting to it from both a PowerMac running Tiger and a MacBookPro running leopard.I can connect no problem from a machine running Slack12.2, have not setup port forwarding on my router to connect remotely yet.My Debian machine is running the latest stable release of squeeze with KDE4.I originally tried this with RealVNC Enterprise for OSX but I'm not gonna buy it so I need another alternative after the 30 day trial ends as they have no free version for OSX.
The situation is that I do freelance graphic design on the PowerMac with Cinema4D and Photoshop so I spend most of my time on that machine which is located in my home studio in my attic. Aside from the MacBook and a Dell desktop(family machine)all my other machines and network hardware are in the basement. So to go from the attic to the basement everytime I need to do something on another machine is not practical, and the only other machine I need to access on a regular basis is the Debian box in the basement, this makes the most sense.
I also have a 14 year old living in the house and he's fascinated by all this and will meddle in anything he gets the chance to so all the Linux machines and network hardware need to be behind lock and key.
Now that Ubuntu 10.04 has multi-touch capabilities built-in, if I do not have a multi-touch screen or surface device, can I get 2 USB mice and get 2 pointers on the screen? One for the right hand and one for the left hand as I am ambidextrous, and would find it very convenient to have 2 mice.
View 4 Replies View RelatedIm running 64bit centos 5.6 and using virt-manager.On one of my guest OS's, Windows 7, The max Physical CPUs is 2, you can have unlimited CPU Cores however. (like my machine i use for work has 1, 4 core processor).The issue im having is xen only allows you to set the vcpu arguemnet in your xen config file. How can i set it so that 1 CPU has several Cores just as windows would recognize this machine if i were installing directly to the hardware vs via a VM.Ive searched for 2 days staright trying to address this issue, very little progress, Does anyone know where a XEN support forum is? all i get is the citrix xen support forums.
here is the best info i have found on this, but i dont know how to change this for my CPU to work, when i enter this in my xen config it essentially ignores it and just takes the value of vcpu= so windows shows 2 CPUs each with ONLY one core. Id like 1 or 2 CPUS showing Several cores.The physical Hardware is 2x Xeon 5300 Quad Core CPUs.

I have a server and I have a few computers connected to it via a Airport Extreme. Using network cable. So when Im uploading,(ftp) IE using a lot of the network "space" the other computers on the network gets kicked out. So what is going on? My Airport Extreme is doing fine, but my other clients just get kicked out. If I pause the upload, everything is okay again. The whole network is 1 gigabit, clients, everything.

View 1 Replies View RelatedI am working on a PHP enabled webpage that will allow a user to select multiple files and directories to upload from a local machine to an ftp server. I am comfortable with uploading the files from the machine to the server. The problem is making it easy to select all the desired files. What I would like to do is create an expandable file tree that lists all the directories and files on the local filesystem. From there, the user should be able to select directories and files using checkboxes. Upon clicking submit, all of the selected files should be fed into an array of files that can be sequentially uploaded to the ftp server.

View 5 Replies View RelatedI've made a simple headless home server based on:
1. Motherboard Asus AT4NM10-I (Intel NM10, PCI)
2. CPU integrated Intel Atom D410
3. 2 Gb of RAM
4. Network Card D-Link DGE-528T 10/100/1000 Mbit/s
5. OS Ubuntu Server 10.04.2 (All installed packages are up to date)
Storage build under LVM based on:

2. Hitachi SATA 2000Gb Deskstar 7K3000 - 2 Tb, 7200/64 Mb.
So found one issue: When torrent upload speed reaches peak speed (160-200 Kbytes/s) huge read slowdown happens. Server becomes almost unreachable... It allows to connect via putty but it takes a lot of time.
Tested top stats during those lags (Deluge, Transmission) - 10-15% CPU usage.
So I think the problem is in LVM and not in CPU.
How is it possible to find weak place in system to avoid those lags... Cause if torrent is seeding it's impossible to watch movies through network form that server.
I am uploading the incremental backups using duply/duplicity using the sftp-module. As the initial upload is pretty big and runs several days (more than 50GB over a 1Mbps-line) I am confronted with the problem that other users in the network experience slowdowns when I upload.
I would like to run a script every n minutes which pings a host in the internet (second hop of the traceroute for example). If the response time is less than a value (150ms), the script throttles the upload for one specific host and protocol. Traffic to the local net (Samba mainly) should be unaffected. I cannot use the QoS of the firewall/router. Also I would like the penalty to be removed if the ping is quicker (loess than 70ms for example) I looked at trickle, and some other out-of-the-box shaping tools but they do not give me the possibility to change the rate while the upload is running.
I would now write a script in perl which uses [URL]some wrapper for iptables combined with some ping module [URL] Also I was trying to get the proof of concept before I start coding: (I haven't verified if this works yet)

I have a home server based on Ubuntu Linux 10.04.2.
Hardware:

Lan - D-Link DGE-528T Gigabit Adapter
Provider gives 8/2 Mbit ADSL connection.
So tried Deluge and Transmission, and integrated or external network card and no luck.
When torrent file is being seeded on top speed network starts freezing, server almost unreachable, video freezing when watching it by LAN from server... etc...
When I pause upload - everything starts working ok!

View 1 Replies View RelatedI have a web server in my kitchen with apache running on it. Since the upload speed is quite low due to my isp I would like to execute a bash script that uploads a file to another server through a website (which is htaccess protected) The idea in general: Someone with access to my website browses through a folder, copies a file path to an input form and presses "upload". Rather than executing a bash script directly I could have a cron job running in background that finds the path and then uploads the file to the other server I have userspace on and is accessible via sftp/ssh. The file would be than erased later after a couple of days or so. That person would be able to access the file with higher speed some time later without logging in via ssh and doing all that manually.
View 2 Replies View RelatedWe're having an issue with HTTP POST file uploads on our two Ubuntu PCs. For some reason, whenever one of our users attempts to submit a file in an HTML form, the request times out, usually with a 500 Internal Server Error message. This problem is not limited to one site, but occurs on all sites that use file uploads. Also, the problem does not appear to be with our network, as a Windows 7 PC on the same network can upload files to the same sites without any difficulties. The problem is not browser-specific; we have tested with Firefox, Epiphany, and Google Chrome and all produce the same results. The issue is relatively new, and was first observed within the last month; before this time, both machines had no problems uploading files.
Does anyone have ANY idea what could be causing this? I've tried a number of things, including rebooting the PCs, rebooting the network, disabling IPv6, etc. I'm not very experienced in Linux system administration, but I can use the terminal and am familiar with some terminal-based diagnostic tools, so if you need any additional info or want me to try something, please let me know! I've exhausted my own computer knowledge with regards to finding a solution to this problem.
Ive looked around and can't seem to find an answer to this. If I use any of my places menus, home, downloads etc, M-Player starts, not Firefox and uploads all the files to a playlist
