  • How can I limit the upload/download bandwidth on my CentOS server?

    - by Dan Nestor
    How can I limit the upload and download bandwidth on my CentOS server? This is a box with a single interface, eth0. Ideally, I would like a command-line solution (I've been trying to use tc), something that I could easily switch on and off in a script. So far I've been trying to do something like tc filter add dev eth0 protocol ip prio 50 u32 police rate 100kbit burst 10240 drop but I'm obviously missing a lot of knowledge and information. Can somebody help with a quick one-liner? Many thanks, Dan

  • Allow READ access to local folders in 2003SBS AD

    - by Dan M.
    Have a SBS2003 client with a mess of a domain that is in process of being cleaned. But, for the life of me I cannot find a setting that will allow write access to the local hard disk for domain users with redirected profiles(to the server). This is needed only for one program that will not follow a symbolic link to the network path, instead it seems to be hard coded to the %appdata% folder but only on the c: drive.... So question is how can I allow "Domain users" write access to the local %appdata% directory? I have tried setting it manually on a machine but it kept resetting to RO no matter how many times I tried. Everytime I would uncheck the RO property it would reset sometime right after i hit OK. Thanks in advance! Dan

  • Too big a difference between Loud and Quiet when watching DVD's... constantly have to adjust volume.

    - by Dan
    It is hard for me to find the right volume for my computer to watch my dvd's on because it seems like most reasonable volumes become overwhelming at the loudest parts of a movie and it is hard to even make out the dialog at the quietest parts. I find I'm constantly adjusting the volume during the course of a movie. Are there ways to make the difference between the louds and the quiets not so extreme? (both computer related solutions and non-computer related solutions welcome). Like moving my speakers across the room and increasing the volume? or the opposite? Or would would the extremes be less noticeable if I used headphones? Are there movie players that might have more complex sound adjustment features? If there is a software solution out there for linux that would be great too. Thanks, Dan

  • Is there a way to attach Ruby Net::HTTP request to a specific IP address / network interface?

    - by Dan Sosedoff
    Hello, Im looking a way to use different IP addresses for each GET request with standard Net::HTTP library. Server has 5 ip addresses and assuming that some API`s are blocking access when request limit per IP is reached. So, only way to do it - use another server. I cant find anything about it in ruby docs. For example, curl allows you to attach it to specific ip address (in PHP): $req = curl_init($url) curl_setopt($req, CURLOPT_INTERFACE, 'ip.address.goes.here'; $result = curl_exec($req); Is there any way to do it with Net::HTTP library? As alternative - CURB (ruby curl binding). But it will be the latest thing i`ll try. Suggestions / Ideas?

  • What is the best way to keep database data encrypted with user passwords?

    - by Dan Sosedoff
    Let's say an application has really specific data which belongs to a user, and nobody is supposed to see it except the owner. I use MySQL database with DataMapper ORM mapper. The application is written in Ruby on Sinatra. Application behavior: User signs up for an account. Creates username and password. Logs into his dashboard. Some fields in specific tables must be protected. Basically, I'm looking for auto-encryption for a model properties. Something like this: class Transaction include DataMapper::Resource property :id, Serial property :value, String, :length => 1024, :encrypted => true ... etc ... belongs_to :user end I assume that encryption/decryption on the fly will cause performance problems, but that's ok. At least if that works - I'm fine. Any ideas how to do this?

  • SAS: add comment to lst ouput file

    - by Dan
    In SAS, How do I add comments to my .LST output file. Like adding a comment saying "This is the output for tbl_TestMacro:" right before doing a proc print? So that my output file will read: This is the output for tbl_TestMacro: Obs field1 field2 1 6 8 2 6 9 3 7 0 4 7 1 Instead of just: Obs field1 field2 1 6 8 2 6 9 3 7 0 4 7 1 Thanks, Dan

  • Locate RFID tag using iPhone

    - by Dan
    Hi all, I am looking into building an app (on my laptop to start) that would be able to locate the signal emitted by an RFID tag (non passive). Say I attach this to my key ring, what would be required of the application to triangulate the location of the RFID tag in a 10m range. Would this even be possible using this technology? I see some older posts here so wondering if there have been any tech breakthroughs in this area since then? Dan

  • Python: Create a duplicate of an array

    - by Dan
    I have an double array alist[1][1]=-1 alist2=[] for x in xrange(10): alist2.append(alist[x]) alist2[1][1]=15 print alist[1][1] and I get 15. Clearly I'm passing a pointer rather than an actual variable... Is there an easy way to make a seperate double array (no shared pointers) without having to do a double for loop? Thanks, Dan

  • What is html5 canvas?

    - by Dan
    I'm a little confused to what html5 canvas is. I've been told it is javascript, but it seems to be a much bigger deal? What makes it different than javascript? Why is it so amazing? Does it do other things than javascript? Thanks, Dan

  • How do I stop myself from redesigning my Silverlight screens? Is there a theme that looks like Sket

    - by Dan Ryan
    Whilst working in Silverlight I am always fighting the urge to work on the screen design rather than coding the behaviour (which is what I should be doing). My cunning plan is to find a theme that looks something like MS SketchFlow or Balsamiq which will remind me of the draft nature of the screens whilst being somewhat prettier than the default look & feel of Silverlight. Does anyone know of such a theme? Alternatively can anyone give advise on how they overcame there design addiction :) Thanks, Dan

  • Displaying Video4Linux frames with LessTif

    - by Dan
    Hi everyone, I have a simple test application (in C) that grabs mmaped frames from my v4l device. And now, I'd like to display these frames within a tiny LessTif application (like gnome cheese, but only displaying the frames - nothing else). Do you have an idea how to implement such a LessTif program? Thanks, Dan

  • Why am I getting a warning that windows is logging on with a temporary profile to run a task scheduler task?

    - by Dan C
    I am having a strange problem with the Windows Server 2008 Task Scheduler. I have to run a small command-line application every few minutes. This application just executes a quick web service call on the localhost and adds an entry to a log file; so it should not need anything special in terms of permissions. First, I created a new user account "my_scheduler" just for the task. This account is a member of the Users group (not sure what other settings I should turn on/off) and set it's password to not expire. I then create a task to run the application every few minutes. I set it to "Run whether user is logged on or not" and turned on "Do not store password. The task will only have access to local resources" (I did this since it's not hitting anything on the network. I did not turn on "Run with highest privileges" since it does not seem to need them. I set the schedule to "After triggered, repeat every 30 minutes for a duration of 1 day" and "Allow task to be run on demand" (no other settings enabled). However, I notice that in the Event Log, I see a bunch of these warnings whenever the task is run: "Windows cannot find the local profile and is logging you on with a temporary profile. Changes you make to this profile will be lost when you log off." Even though I get the warning, the task is executing (I see the log entries appearing). Another (possibly related) issue is that I also see that it's starting multiple copies of the task (within a few seconds of each other) even though it should only start one. This is also a big problem. Any idea how I can fix this? Thanks in advance, Dan
