  • Apache: set aside specific number of servers for a single "high priority" script

    - by Disco
    I have a bunch of scripts, but some of them are higher priority than others: /var/www/normal-priority/script1.pl /var/www/normal-priority/script2.pl /var/www/normal-priority/script3.pl and /var/www/high-priority/script1.pl /var/www/high-priority/script2.pl /var/www/high-priority/script3.pl All running under mod-perl. They reside in separate directories. From time to time, the normal-priority scripts get very busy, and the httpd servers "swamp out" the less frequently called high priority ones. Is it possible to set aside n httpd servers so that they only listen for the "high priority" scripts?

  • Set Up Port-Forwarding on Netgear N300 Router

    - by Smitty
    I have a Netgear N300 router that has DynDNS.org as a preset DDNS option. After setting it up it (unsurprisingly) sent traffic directly to my router. I'm essentially using this to connect remotely to my home (virtual) machine/s. From what I've read, it seems like I need to set up port forwarding. I tried forwarding "all" inbound traffic to a specific IP but that just didn't work. What am I doing wrong? Also, I just noticed I get this error after applying the settings: "The specified port(s) are being used by other configurations. Please check your configurations of Remote Management, Port forwarding, Port Triggering, UPnP Port Mapping table, RIP, and Internet connection type"

  • Need advice on how to set up live video streaming to web/mobile devices

    - by jasondewitt
    I have a bunch of live udp video streams that currently are viewed by set top boxes in my network. I would like to pick this video up (I can do this with vlc now) and stream it out to other non-STB endpoints (webpage or a phone/tablet of some sort). Right now I am able to pick up the udp stream with vlc and convert it to an http stream on port 8080 of my vlc box. Then I can use the vlc client to pick up and watch that video stream. This is where I'm not sure where to go with it. I really doubt I would want everyone who is watching the video to make a connection back to my vlc server that is doing the encoding, so how do I distribute this live video to the people who want to see it?

  • Set up an Email server on intranet without domain

    - by Devdatta Tengshe
    I work in a small office with about 35 people and we are all on a intranet. This network is not connected to the internet. Is it possible to set up an email server, with which we could send emails to each other? (We don't need to send emails outside our network.) I cannot use a messenger service like Openfire, since the messages could be asynchronous, and we'd like to get those emails in a email client like Thunderbird. Another obstacle we have is that we do not have a domain name. Any ideas on which free (as in beer) software could be used? We have both Windows and Linux machines.

  • Set Wordpress Homepage

    - by user2210274
    I am currently setting up a simple Wordpress website. I am attempting to set a specific page as the Static Home page. I have read wordpress documentation on setting the homepage, and upon load, it directs to the correct page, but does not replace the previous home page. Please see here: http://tinypic.com/r/33cxiip/5 The home page is located underneath the contact us menu. Ideally I would like it under the Home tab. Any ideas? Thanks!

  • Maintaining a set of (virtual) windows XP machines

    - by Frank Meulenaar
    I have a small set (currently 3, going to 6, not going to be more than 10) of (virtual, vmware workstation) windows XP machine's. They are similar but not exactly the same. I'm currently rolling out windows updates etc by hand: start machine 1, update, close, etc; I'd like to review the updates first before the clients can install them. Incidentally there are also other updates to be performed: changes some files on all machines, install new Java versions, etc. What's a good way of doing this automatic? I tried to search for this but things like Active Directory seem overkill to me.

  • Set an Excel cell's color based on multiple other cells' colors

    - by Lord Torgamus
    I have an Excel 2007 spreadsheet for a list of products and a bunch of factors to rate each one on, and I'm using Conditional Formatting to set the color of the cells in the individual attribute columns. It looks something like this: I want to fill in the rating column for each item with a color, based on the color ratings of its individual attributes. Examples of ways to determine this: the color of the category in which the item scored worst the statistical mode of the category colors the average of the category ratings, where each color is assigned a numerical value How can I implement any or all of the above rules? (I'm really just asking for a quick overview of the relevant Excel feature; I don't need step-by-step instructions for each rule.)

  • Domain controller in cloud, how do we set up local BDC

    - by brian b
    We have a domain controller (exchange box) hosted at our hosting provider. We need to set up a local domain controller so we do a VPN and local authentication tasks. I can make the PDC accept all connections from our Office IP. How do I get the office router to correctly allow two way communications between the PDC (cloud) and the local DC. Is there a list of ports I need to pass through to the local DC? Thanks! "PDC" and "BDC" used for clarity--I know that the concept is obsolete.

  • How to add recently set cookies to nginx's access log

    - by etoleb
    I'd like to include cookie data in an nginx access log like so: (simplified example) log_format foo '$remote_addr "$request" $cookie_bar'; access_log /var/log/nginx/access.log foo; This works great on requests that already have a cookie "bar", but for the first request to my server nginx will report "-" as the value of "bar". It seems like my problem is that nginx is looking at the request headers for the cookie value. Is there a way check for a Set-Cookie in the response and use that as a fallback?

  • transparently set up Windows 7 as remote workstation

    - by Áxel
    Maybe is a very basic question, but I can't find the exact terms to Google for it and find the concrete answer to my doubt. Suppose we have several PCs in which individual employees work. One of them has an extremely powerful CPU, and it's very useful to use that computer to perform heavy computations, but go there and set up your task means its user has to stop working for a while. Is it possible to allow a secondary user account to remotly log in, for example via Remote Desktop, and work with a full user environment, while the main user keeps working under his user session? I've used remote desktop many times in the past, but it always blocked current user session, or even terminated it. Lots of thanks in advance guys.

  • How to set up Apache 2 to serve only subdirectories

    - by Lynden Shields
    I have 3 sites which need to be hosted on a web server (apache2 from repo running on Ubuntu 12.04). They are each in their own subdirectory within /var/www/ I would like apache to serve files from the relevant directories only if the directory name is given in the URL, but not serve the /var/www/ directory itself. E.g: http://1.2.3.4/site1/ should work and serve the index from /var/www/site1/index.html, but http://1.2.3.4/ should not serve anything. Currently, I can't get the url to point to the directory. Either I can get http://1.2.3.4/ to serve everything within /var/www/ (including /var/www/site2/secretstuff/), or I can get the root http://1.2.3.4/ to serve one of the subdirectories (/var/www/site1/). This is unacceptable site 1 needs Indexes enabled but the others must not. I just want to make site1's config only respond to requests of the form http://1.2.3.4/site1/* and not handle requests of the form http://1.2.3.4/ I do not have a domain name set up so I can't use subdomains.

  • Looking up a value, depending on which set of dates another date falls between

    - by Ruffles
    Hello, and apologies if this is a duplicate - if you could point me in the direction of any existing answers, that would be great. I have a set of date ranges in Excel, each of which has some kind of label. e.g. LabelA 01/01/10 31/01/10 LabelB 01/02/10 28/02/10 LabelC 01/03/10 31/03/10 If I have another date, I would like to look up the label relating to the date range within which this date falls. e.g. For 15/02/10 I would like to return LabelB. I know that the date ranges will not overlap, although there could be a gap between the end date of one, and the start date of the next.

  • Set generic iptables rules?

    - by tftd
    This may be a really dumb question but how can you open a port on multiple interfaces without defining the interfaces? For example how do I open port 22 on all interfaces? On my machine I have some interfaces that are dynamic and may or may not be available so I have to set "generic" rules. This code is not working for me but I can't figure out why: # My default policy is to drop the input. # The other policies are required like that. $IPTABLES -P INPUT DROP $IPTABLES -P OUTPUT ACCEPT $IPTABLES -P FORWARD ACCEPT $IPTABLES -t nat -P POSTROUTING ACCEPT $IPTABLES -t nat -P PREROUTING ACCEPT $IPTABLES -t mangle -P OUTPUT ACCEPT $IPTABLES -t mangle -P PREROUTING ACCEPT #Open port 22 on all interfaces ? $IPTABLES -A INPUT -p tcp --dport 22 -j ACCEPT So apparently there's something wrong with the last line... but I can't see it?

  • Ubuntu Volume overriding settings set in Alsamixer

    - by Hayek
    Problem: How do I "lock in" the volume I set through alsamixer? I'm running Ubuntu 9.10. I adjusted the bass/treble columns in alsamixer but changing the system volume resets them all back to 100% I did save the settings by running alsactl store but everything is reset once I touch Ubuntu's volume icon in the top menu bar. This is rather painful because the computer is hooked up to a 650watt system with a massive subwoofer. As much as I enjoy my music, there's no need to have the walls vibrate :) What can I do to prevent Ubuntu from overriding the settings?

  • How do I set permissions on a Server 2003 folder

    - by Richard210363
    Hi There, In my part time position as entire IT department at my Office ( I'm a MCSD developer normally ) I have been asked to change a shared folder. Only I don't really understand all the Shared / Security options. I have a folder that must be accessed by 2 people in the company (and no one else). They both must have read/write/edit and change access. They must be able to read/write/edit each others files; existing or newly created. Should be easy but I'm a bit overwhelemd by all the choices. What should I set? Thanks for your help richard

  • Can I set osx to boot with several spaces containing a different set of apps in each?

    - by Jay
    When my system boots I would love to have it to create three spaces: First Space: email and things (my to do list program) Second Space: textmate and a browser containing first site I am developing Third Space: textmate and a browser containing my second site Is it possible to set it up to do that each time? I'd prefer not to use the reopen windows option on shutdown because most days I have a bunch of things open that I won't need the next day. Thanks. UPDATE: I found TotalSpaces2 and it will open all the same spaces when I reboot. I suppose that I might need some kind of hack to get the applications to start in the appropriate space at boot.

  • Set up homeserver with single IP to host multiple sites on Ubuntu [closed]

    - by Ortix92
    I am trying to set up my homeserver so it can function as a regular server one would rent. I am running Ubuntu 12.04 LTS with openpanel. I have a single static IP address. I am used to having two addresses and pointing them to NS1.domain.tld and NS2.domain.tld and setting up the propper DNS records. I would also like to mention I am somewhat new to DNS zones. Either way, how would I go about setting this up correctly (in openpanel) with just a single IP address if possible at all? I have also read about free solutions online, but I would like to keep everything secure and private so other people can't peer into my data somehow. Thanks!

  • Looking for concise set of instructions for upgrading Vmware 5.1 to 5.5

    - by Michael Martinez
    I'm trying to find a set of instructions for upgrading Vmware (ESXi and Vsphere) from 5.1 to 5.5, but all I'm finding online is a bunch of separate, incomplete knowledgebase articles which is making it difficult to get an overview of what's involved. What I'd like is a single, concise document that lists the steps involved. It could be a free online article, someone's blog, a small booklet, someone here who takes the trouble to write it out. Does such a thing exist? If so, can you provide the reference or even provide the text here. I'm running a very small, simple environment consisting of two ESXi hosts and Vsphere Standard edition. Thanks.

  • Set windows `always below bottom-most`?

    - by ???
    There is an "Always on topmost" menu option for windows. I'm not sure if it's related to compiz or metacity. I want to set the Totem player or Cheese the WebCAM player, always below the bottom-most, so I can view the movie when I'm working. And, let the "Always below the bottom-most" windows be excluded in the windows list is even better. If there is no such function yet, where should I begin if I want to develop one? It's Compiz or Gtk or XFB or something else?

  • Why create a Huffman tree per character instead of a Node?

    - by Omega
    For a school assignment we're supposed to make a Java implementation of a compressor/decompresser using Huffman's algorithm. I've been reading a bit about it, specially this C++ tutorial: http://www.cprogramming.com/tutorial/computersciencetheory/huffman.html In my program, I've been thinking about having Nodes that have the following properties: Total Frequency Character (if a leaf) Right child (if any) Left child (if any) Parent (if any) So when building the Huffman tree, it is just a matter of linking a node to others, etc. However, I'm a bit confused with the following quote (emphasis mine): First, every letter starts off as part of its own tree and the trees are ordered by the frequency of the letters in the original string. Then the two least-frequently used letters are combined into a single tree, and the frequency of that tree is set to be the combined frequency of the two trees that it links together. My question: why should I create a tree per letter, instead of just a node per letter and then do the linking later? I have not begun coding, I'm just studying the algorithm first, so I guess I'm missing an important detail. What is it?

  • Can someone describe the nested set model from a C#/LINQ perspective?

    - by Chad
    I know the nested set model doesn't pertain to the C# language or LINQ directly... it's what I'm using to develop my web app. For hierarchical data (categories with sub-categories in my case), I'm currently using something similar to the Adjacency List model. At the moment, I've only got 2 levels of categories, but I'd like to take it further and allow for n levels of categories using the nested set model. I'm not quite clear on how to use it in a C# context. Here's the article I'm reading on the nested set model. Though this article cleared up my confusion some, I still have a big ?? in my head: - Is inserting, updating or deleting categories tedious? It looks like the left and right numbers would require re-numbering... what would the LINQ queries look like for the following scenarios? Delete a child node (re-number all node's left/right values) Delete a parent node (what do you do with the orphans?) Move a child node to a different parent node (renumber again) If my understanding is correct, at all times the child node's left/right values will always be between the parent node's left/right values, am I correct? Seems easy enough, if only the categories were static... most likely I need to spend more time to get my head around the concept. Any help is greatly appreciated!

  • form layout in drupal from a module

    - by EricP
    I created my own module called "cssswitch". I'm trying to create my own html layout to display the admin form portion of the module. I understand how to use the hook_form_alter() to modify form elements, but I need to create the entire form layout to make some fields appear next to each other. It seems I need something like the way I have the frontend view of the node displayed with theme_cssswitch_display(), but for the admin part of the node. function cssswitch_form_alter(&$form, $form_state, $form_id) { switch($form_id) { case 'cssswitch_node_form': $form['hour_start']['#prefix'] = '<div class="start-box">'; $form['ampm_start']['#suffix'] = '</div>'; $form['ampm_start']['#attributes'] = array("style" => "border-width:2px;"); break; } } function cssswitch_theme() { return array( 'cssswitch_display' => array( 'arguments' => array('node'), ), ); } // to display the view of the node function theme_cssswitch_display($node) { $output = '<div class="cssswitch-cssfilename">Filename: '. check_plain($node->cssfilename).
