  • Network load balancing, efficience and limits?

    - by Vimvq1987
    I'm about to study about NLB on Windows Server 2003. It archives both of my interests now: scalability and high-availability. But I don't know about its power in production environment. Is NLB a efficient solution? How does it implement in real-world? Is it popular? What are its limit? Thank you so much for answering my questions. :)

  • How to limit a process to a single CPU core?

    - by Jonathan
    How do you limit a single process program run in a Windows environment to run only on a single CPU on a multi-core machine? Is it the same between a windowed program and a command line program? UPDATE: Reason for doing this: benchmarking various programming languages aspects I need something that would work from the very start of the process, therefore @akseli's answer, although great for other cases, doesn't solve my case

  • The real differences between Red Hat Enterprise Linux (RHEL) and CentOS

    - by w00binda
    I know that "the vast majority of changes made (by CentOS team ndr) will be made to comply with the upstream vendor's re-distribution policies concerning trademarked names or logos" But I'm looking for a way to measure the real differences between RHEL and CentOS. My goal is to demonstrate "scientifically" that is possibile to use CentOS for development and testing purpose and use RHEL in the production environment. Any suggestion? Thanks in advance.

  • Checking rtp stream audio quality.

    - by chills42
    We are working in a test environment and need to monitor the audio quality of an rtp stream that is being captured using tshark. Right now we are able to capture the audio and access the file through wireshark, but we would like to find a way to save the audio to a .wav file (or similar) via the command line. Does anyone know of a tool that can do this?

  • How do I map a network drive in Ubuntu? I want to save my Firefox downloads directly in the mapped n

    - by NJTechie
    I work in an environment wherein files are exchanged over email which are then processed into databases. In Windows, mapping a network drive and storing files directly to a folder in the network drive from Firefox/Chrome downloads is a breeze. How to achieve the same in Ubuntu? I don't see the SFTP'ed drive/directory as options in Firefox- Downloads setup. Thanks in advance!

  • AutoHotKey script not recognizing Windows Explorer

    - by SaintWacko
    I've made a script that will set an environment variable to the path in the current Explorer windows when its hotkey is pressed. However, I want this to only trigger if the active window is an Explorer window. This should do it: #IfWinActive ahk_class ExploreWClass|CabinetWClass #p:: SetPath() return #IfWinActive But for some reason it isn't. Is there something I'm doing wrong?

  • Unattended Install of Zend Server license

    - by Zoop - Josh
    I have a Zend Server 5.6 development license and I wanted to know if there is a way to apply the license during install, rather than via the web interface after it has installed. I ask because I administer our server environment via Rightscale and have automated the creation of the server, however it still requires manual input for the license details. We regularly fire up a staging server to do final tests before pushing to production and it would be great if it were completely hands off.

  • Large scale file replication with an option to "unsubscribe" from a replicated file on a given machine

    - by Alexander Gladysh
    I have a 100+ GB files per day incoming on one machine. (File size is arbitrary and can be adjusted as needed.) I have several other machines that do some work on these files. I need to reliably deliver each incoming file to the worker machines. A worker machine should be able to free its HDD from a file once it is done working with it. It is preferable that a file would be uploaded to the worker only once and then processed in place, and then deleted, without copying somewhere else — to minimize already high HDD load. (Worker itself requires quite a bit of bandwidth.) Please advise a solution that is not based on Java. None of existing replication solutions that I've seen can do the "free HDD from the file once processed" stuff — but maybe I'm missing something... A preferable solution should work with files (from the POV of our business logic code), not require the business logic to connect to some queue or other. (Internally the solution may use whatever technology it needs to — except Java.)

  • How to associate localhost in Snow Leopard to a specific ip ?

    - by Patrick
    I've disabled the web server on Snow Leopard, and I'm using an emulated Ubuntu with Lighttpd web server. In order to access to the web pages I need to specify the ip of the emulated machine. However I now need to associated such ip with "localhost" in Leopard environment. When I type localhost in Leopard I actually want to visit the localhost on the Ubuntu machine. Do I need apache on leopard to make the forward or can I change network settings in Leopard or what ? thanks

  • What OpenSource iSCSI appliances/apps support windows clusters?

    - by Jimsmithkka
    I have been wanting to experiment with Windows clustering systems in my spare time, so I need a free, preferably open source, iSCSI Target that can support 2k3 and 2k8 fail-over and possibly High availability clustering. I have tried the ubuntu iscsi target package in a vmware environment, but it fails at the 2k8 tests. In simple terms I want to build a "Poor man's San" for windows and have it be able to do more than just be drives.

  • How do you put clips from a DVD into a website?

    - by Nathan DeWitt
    I have a promotional DVD from a client, and they want to put clips from it on their website. I'm in a Windows environment, so I'm looking for a decent video editor program, free would be preferred. Then I guess I'd have some kind of flash-based player to embed in the website... What do you recommend?

  • Utilities for finding x/y screen coordinates

    - by slothbear
    I have an application that needs the user to enter the x and y location of a couple of items on the screen. [Yes, this is crap and I'll replace it, but for now...] On Mac OS X, I'm using Snapz Pro X. When I choose to take a snap of a selection, the interface displays the mouse cursor location. This is OK for my personal use, but I can't ask users to buy a $69 program for this function. I thought I had a solution with the built-in program "Grab", but it reports the coordinates from the bottom left, and I need it from the top left. I don't have access to Windows; not sure what to use there. I've not even been able to come up with good search terms since mouse and coordinates and x/y are so common. Ideas are welcome there. Extra credit: same x/y finder for Linux. A Java program would be OK too, since the main application is in Java.

  • Is it possible to control the whole Gnome desktop with vi-like commands?

    - by roy
    I know with readline you can use emacs or vi commands to edit the input of several interactive text programs. I wonder if there exists such a similar facility to control the whole desktop in Gnome or in any other desktop environment. Maybe it could be a program that intercepts keystrokes and process them in the way vi does, translating sequences of characters to desktop commands and delivering to the active window only the text that is writen in insert mode. Do you know some tool like that?

  • Single machine domain with Windows 7 OS

    - by Robert Koritnik
    Is it possible to setup one single machine with Windows 7 x64 OS and somehow make it work as if it's part of a certain domain? So domain controller would be simulated in some way? I would like to avoid VMs and make it actually work on one machine with non server OS. Is there even a simpler way of doing it? Why: I have to setup development environment for Sharepoint 2010 and it will make my life much easier if my machine would be part of a domain.

  • Ways to make USB Firefox faster

    - by MichaelKay
    I have several laptops so I use a USB key version of Firefox to keep my environment as I move around. I followed the suggestions offered on the Firefox web site (turn off the cache and history etc.) and its better but still much slower than the normal version. Other than buying a new, super fast flux-capacitor based USB key, what other tips and tricks can I use?

  • Oracle Virtualbox on statically compiled kernel

    - by aking1012
    I can't seem to find any documentation on the subject. I'm working on putting together a linux install for a fairly "dirty" environment. Best practice there would be a statically compiled kernel with no module support. I can already do the customizations to strip out unnecessary drivers/etc to get the performance and disable module support. Does anyone have a link or any ideas on how to get the Oracle Virtualbox module (not the OSE one, I need USB passthrough) compiled in?

  • Change drive letter of DVD drive

    - by NickC
    I am trying to use a Drive Maps GPO on Server 2012 - User Configuration - Preferences - Windows Settings - Drive Maps. Problem is I want to map a drive to D: but this is automatically assigned to the DVD drive. Question is can I prevent D: being used as the next drive letter when Windows 8 boots up? I seem to recall in early version of Windows, or maybe it was Novell, a first_drive environment variable for this purpose.

  • Benefits to private networks between virtual machines on an ESXi host?

    - by arex1337
    I'm planning this development environment with a few database servers, and originally thought I would have a few private networks. I then thought it might be unnecessary as the ESXi cluster already provides redundancy with 4 NICs (in my case) and should manage the network traffic pretty intelligently, right? Two private networks Zero private networks What are the advantages/disadvantages between the two shown configurations - on an ESXi 4.1 host?

  • Relevance and Necessity of SNMP

    - by Adam Tannon
    Edit: I am in the process of designing a Java-based monitoring tool that will send back periodic "health checks" of a Java app deployed to a cluster of GlassFish servers. I am trying to figure out the best protocol for this monitoring tool to send information back to the monitoring server on. After an initial research effort on my part, it seems like SNMP is just a protocol for monitor-type applications to communicate the "health status" of something (a part of a network, a server, a cluster, an application, etc.) to the rest of the network. If the above is incorrect, please correct me!!! Assuming the generalization is more or less accurate, my next question is: why is this a protocol!?!? In the age of REST/SOAP/TCP protocols, why is there the need for a standardized protocol that only fits one type of application (monitoring)? In other words, if I'm a developer assigned to building a new monitoring tool that periodically polls a server and reports on its CPU and available memory, what advantages does SNMP give me over just POSTing to a RESTful API via plain 'ole HTTP? I'm sure I'm missing something here - I just need someone to help connect the dots! Thanks in advance!
