  • Linux: How to delay hddtemp service start at boot until all hdd are visible?

    - by Atis
    I live in a hot and humid environment, therefore I monitor the hdd temperature using hddtemp and gkrellm. There is an LSI9211 8i sata/sas controller in my computer. I have drives connected to both my motherboard and the LSI. hddtemp monitors only the drives directly connected to my motherboard after booting the system, therefore gkrellm displays the temperature of those drvies only. Logging in and restarting hddtemp before starting gkrellm fixes my issue, i.e. drives connected to the LSI controller are also visible. It seems that the drives connected to the LSI controller become visible only after hddtemp is started in the boot sequence. I think delaying it would help. How can I delay the starting of hddtemp till all drives are visible? I prefer a way to check if drives are visible to the delay of a specific amount of seconds.

  • What service do you use for music on hold?

    - by Russ Warren
    This may not be a sysadmin question for some, but it is definitely a hurdle I have to jump as the sysadmin for my company. We recently rolled-out a company wide VoiP system (Switchvox, to be exact) that has come preloaded with some royalty-free music on hold. Our customers have been complaining that the music on hold sounds like "funeral music." This may be the case (although I wouldn't want it played at my funeral), but it is all we have and we aren't willing to be sued over using music that isn't properly licensed. So, that brings me to the question asked in the title -- what and/or how do you provide decent music on hold? I'm assuming many people here use a PBX that allows customized music, so this has to apply to many of you. We've been looking at some sites that allow you to download royalty-free music for a one-time fee, but the music seems...lame. Something like a one-year subscription from ibaudio.com seems to be the best bet so far. Have you been able to discover something a little more mainstream for a decent licensing fee? Thank you. EDIT: Our PBX allows the playback of MP3 and OGG files, but does not allow streaming of a live audio source, Internet-based or otherwise. It also does not allow the use of a "line-in" source such as a CD player or radio. Don't let this stop you from sharing your setup, though. I'm interested in hearing what everyone uses!

  • What freeware/floss tools are available to help load data into SPSS?

    - by tardate
    I'm looking for a solution for producing SPSS format data files for loading into SPSS. The few offerings I can find are all commercial. Has anyone experience with generating SPSS-format data files using open-source, freeware or home-grown solutions? I'm not even sure that the file format is "open". Any hints appreciated (any language is fine, although java, perl or ruby preferred).

  • Windows 7 hangs while loading desktop

    - by Joshua
    I am facing a weird problem. My computer hangs while loading the desktop, and only the background shows up; no icons or bars load. If I power the system on and off about 4-6 times, I may be able to use it normally. The desktop loads normally after rebooting or in safe mode; this only occurs when I start the system normally. I've tried several things to fix it, such as removing all start-up items, but it still doesn't solve the problem. What should I do? I found three major errors in Event Viewer: Source: Microsoft-Windows-DistributedCOM Level: Error DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server: {7D096C5F-AC08-4F1F-BEB7-5C22C517CE39} Source: Microsoft-Windows-DistributedCOM Level: Error DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server: {7D096C5F-AC08-4F1F-BEB7-5C22C517CE39} Source: Service Control Manager Level: Error The Network List Service service depends on the Network Location Awareness service which failed to start because of the following error: The dependency service or group failed to start.

    Hi, BACKGROUND: I am working on a .NET WinForms application now (C#) with an ADO.net database for the data layer. QUESTION: How an I develop this now such that it would be easy to migrate to a model where the data layer is abstracted via a HTTP web-service or REST interface? For example would just use of a standard C# interface with a Factory to obtain a concrete implementation of the interface where this uses ADO.net be the best? thanks

  • How can I obtain raw data from a CVImageBuffer object.

    - by jslap
    Hi, I'm trying to use cocoa to grab images from a webcam. I'm able to get the image in RGBA format using the QTKit and the didOutputVideoFrame delegate call, and converting the CVImageBuffer to a CIImage and then to a NSBitmapImageRep. I know my camera grabs natively in YUV, what I want is to get the YUV data directly from the CVImageBuffer, and proccess the YUV frame before displaying it. My question is: How can I get the YUV data from the CVImageBuffer? thanks.

  • In Zabbix how to zero data when it doesn't comes?

    - by Jader Dias
    If a variable is expected to be fetched every minute, and it doesn't happen, the graph shows the last known value for all the timespan until the next known value. The expected behavior for me is that the graph showed no line, or a line next to the zero, where there is no data. How to achieve this with Zabbix?

  • Can I setup NAT for the same service, two public IPs on different routers to the same private IP?

    - by James
    This might be needlessly complex, but here goes. I've got two Firebox x550e devices. The first has a local IP of 10.0.0.1, public IP 64.x.x.x. The second has a local IP of 10.0.0.10, public IP 70.x.x.x. There is an FTP server on our LAN with a private IP of 10.0.0.55. I've set up NAT rules in each of the Fireboxes, on the first firebox it is 64.x.x.x-10.0.0.55 tcp 21, on the second 70.x.x.x-10.0.0.55 tcp 21. The first rule works fine. I can ftp to 64.x.x.x and everything's good. The second rule doesn't work. ftp to 70.x.x.x results in a connection timeout. The second firebox logs say the connection is being allowed through. The default gateway on the FTP server is 10.0.0.1 (the first firebox) If I change the default gateway on the server to 10.0.0.10, the rule on the second firebox starts working, but the rule from the first firebox stops. Is there some way to make this work for both rules?

  • How to troubleshoot down terminal service/CITRIX sessions, when the process just won't terminate?

    - by Chad
    Running a CITRIX presentation server farm, version 4.5.6 on Windows 2003 sp2. In the CITRIX Access Management Console, I sometimes get a session that shows it's in a down state - but has none of the normal info associated with it (user name, applications, client name, idle time, etc...). It does say which servers it's on, so I check out that server's terminal services manager. I can see the down session but cannot reset it. I get: (Error 7024 - the requested operation cannot be completed because the terminal connection is currently busy processing a connect, disconnect, reset, or delete operation.) So I go to the task manager and look up the processes running under that session id. I see it's one of my published apps, but when I try to end the process - it simply does nothing and the process remains. Any way to get rid of these sessions without a server reboot?

  • Puppet master fails to run under nginx+passenger configuration as rack app, works when run as system service

  • Java multithreaded server - each connection returns data. Processing on main thread?

    - by oliwr
    I am writing a client with an integrated server that should wait indefinitely for new connections - and handle each on a Thread. I want to process the received byte array in a system wide available message handler on the main thread. However, currently the processing is obviously done on the client thread. I've looked at Futures, submit() of ExecutorService, but as I create my Client-Connections within the Server, the data would be returned to the Server thread. How can I return it from there onto the main thread (in a synchronized packet store maybe?) to process it without blocking the server? My current implementation looks like this: public class Server extends Thread { private int port; private ExecutorService threadPool; public Server(int port) { this.port = port; // 50 simultaneous connections threadPool = Executors.newFixedThreadPool(50); } public void run() { try{ ServerSocket listener = new ServerSocket(this.port); System.out.println("Listening on Port " + this.port); Socket connection; while(true){ try { connection = listener.accept(); System.out.println("Accepted client " + connection.getInetAddress()); connection.setSoTimeout(4000); ClientHandler conn_c= new ClientHandler(connection); threadPool.execute(conn_c); } catch (IOException e) { System.out.println("IOException on connection: " + e); } } } catch (IOException e) { System.out.println("IOException on socket listen: " + e); e.printStackTrace(); threadPool.shutdown(); } } } class ClientHandler implements Runnable { private Socket connection; ClientHandler(Socket connection) { this.connection=connection; } @Override public void run() { try { // Read data from the InputStream, buffered int count; byte[] buffer = new byte[8192]; InputStream is = connection.getInputStream(); ByteArrayOutputStream out = new ByteArrayOutputStream(); // While there is data in the stream, read it while ((count = is.read(buffer)) > 0) { out.write(buffer, 0, count); } is.close(); out.close(); System.out.println("Disconnect client " + connection.getInetAddress()); connection.close(); // handle the received data MessageHandler.handle(out.toByteArray()); } catch (IOException e) { System.out.println("IOException on socket read: " + e); e.printStackTrace(); } return; } }

  • X:\ is not accessible. Insufficient system resources exist to complete the requested service. Help [

    - by Katherine
    I keeping getting the error message from above on multiple computers that I administer. I wasn't sure if I should be posting this on SuperUser or ServerFault so my apologizes if it should go there... Basically, I have at least 5 computers of varying ages (some fresh out of the box!) throwing the above error. X:\ is one of our network drives that is mapped for users. Most of the time if you shut down the biggest application it will fix the problem, but it's becoming an increasing issue, and I can't keep running around fixing it manually. I have tried to do some research, but most of it just states the obvious without supplying a permanent fix. The machines are all running Win XP SP3, with at least 2gb of ram. Sorry for the delay in getting back to people... a lot of good questions. To respond back to people... It is a windows 2003 server that houses the file share. We have about 175 users, however i cannot state how many are actually accessing the information at a single moment. Considering that this is our largest file share, I would say that probably at least 100+. The files we work with are large, but not that big considering that we do a lot of graphical and video work. ~50mb. That being said, this is error occurs simply when trying to gain access to the server itself, not actual files. When I say close a program, I mean that it can be any program. It doesn't matter which program. It varies from machine to machine, and from day to day. Some days it is Firefox, some days it is Outlook, some days it is Excel. There doesn't seem to be a common bond behind which application could be causing the problem. Thank you for the articles, and the recommendation on paging files. I will have to look into that. None of our computers are set to hibernate, so I am going to rule that out.

  • Why would some POST data go missing when using Uploadify?

    - by Chad Johnson
    I have been using Uploadify in my PHP application for the last couple months, and I've been trying to track down an elusive bug. I receive emails when fatal errors occur, and they provide me a good amount of details. I've received dozens of them. I have not, however, been able to reproduce the problem myself. Some users (like myself) experience no problem, while others do. Before I give details of the problem, here is the flow. User visits edit screen for a page in the CMS I am using. Record id for the page is put into a form as a hidden value. User clicks the Uploadify browse button and selects a file (only single file selection is allowed). User clicks Submit button for my form. jQuery intercepts the form submit action, triggers Uploadify to start uploading, and returns false for the submit action (manually cancelling the form submit event so that Uploadify can take over). Uploadify uploads to a custom process script. Uploadify finishes uploading and triggers the Javascript completion callback. The Javascript callback calls $('#myForm').submit() to submit the form. Now that's what SHOULD happen. I've received reports of the upload freezing at 100% and also others where "I/O Error" is displayed. What's happening is, the form is submitting with the completion callback, but some post parameters present in the form are simply not in the post data. The id for the page, which earlier I said is added to the form as a hidden field, is simply not there in the post data ($_POST)--there is no item for 'id' in the $_POST array. The strange thing is, the post data DOES contain values for some fields. For instance, I have an input of type text called "name" which is for the record name, and it does show up in the post data. Here is what I've gathered: This has been happening on Mac OSX 10.5 and 10.6, Windows XP, and Windows 7. I can post exact user agent strings if that helps. Users must use Flash 10.0.12 or later. We've made it so the form reverts to using a normal "file" field if they have < 10.0.12. Does anyone have ANY ideas at all what the cause of this could be?

  • Win 7: apps crash, then explorer crashes, then services fail, then boom

    - by snorfys
    Periodically, every 2-3 days one of my systems will go haywire: every app will crash search will fail via the start menu and then explorer will fail. Restarting explorer via taskmanager will cause it to fail again, then it'll BSOD and restart. The eventlog for when this happens goes something like this every time: ERROR: Session "ReadyBoot" stopped due to the following error: 0xC0000188 (supposedly not a problem) WARNING: The maximum file size for session "ReadyBoot" has been reached... (forget where I found out, but also 'not a problem') ERROR: Session "Circular Kernel Context Logger" stopped due to the following error: 0xC0000188 (again, supposedly not a problem) WARNING: The maximum file size for session "Circular Kernel Context Logger" has been reached... ERROR: Faulting application name: Explorer.EXE, version: 6.1.7600.16450, time stamp:... ERROR: Faulting application name: explorer.exe, version: 6.1.7600.16450, time stamp:... ERROR: Faulting application name: svchost.exe_iphlpsvc, version: 6.1.7600.16385, time stamp:... ERROR: The Service Name service terminated unexpectedly. It has done this 1 time(s) That last one happens a number of times but with a different service name. Then finally we have: ERROR: The Service Control Manager tried to take a corrective action (Restart the service) after the unexpected termination of the Server service, but this action failed with the following error: An instance of the service is already running. After that, I have my BSOD and logs complaining that windows started up without shutting down. It's a new machine: Intel i3 530 4gb RAM (Ran memtest for 4 hrs, no problems) 320GB WD/250GB Seagate HDDs (Happened on fresh installs on 2 separate HDDs) Win7 Pro/Ultimate x64 (wife's copy of pro, my copy of ult, no change) Fresh install + driver and windows update (happened without updates as well) I'm at a bit of a loss as to what I can look at next. Especially since it'll work like a charm for 2-3 days and then it's hooped for a night (I'm on it now in fact - no problems).

  • Is it safe to use Email service that provided from webhosting for business use?

    - by Kronass
    I work in a company who uses their web-hosting as their email provider, they use it for normal send, receive and basic contacts management, they use it in customers support, sales and marketing, I would prefer to use a dedicated or professional email hosting instead for this type of work. So for business use is it safe to use the email hosting that is included with hosting package or go with a professional email provider?

  • Accessing array values in jQuery ajax callback function

    - by gibberish
    Values are received through a jQuery AJAX callback, but I've been unsuccessful getting at the values. Here's the ajax call: $.ajax({ type: "POST", url: "ajax/ax_all_ajax_fns.php", data: 'request=edit_timecard_entry&staff_id='+staff_id+'&tid='+tid, success: function(data){ alert(data); } } Here's the code sent out by ax_all_ajax_fns.php: $staff_id = $_POST['staff_id']; $t_id = $_POST['tid']; $rCard = mysql_query("SELECT `staff_id`, `date`, `project_id`, `project_num`, `task_desc`, `hours` FROM `timecards` WHERE `t_id`='$t_id'"); $aCard = mysql_fetch_assoc($rCard); print_r($aCard); // echo $aCard; Of course, I don't want the information print_r'd, I want it echoed. The print_r was used to demonstrate that the correct data was sent out by the PHP script, and it is echoed successfully in the alert() box in the success function. So the correct data is being returned, and (if correctly formatted) it is viewable. The data returned in this way looks like this in the alert() popup: Array ( [staff_id] => 51 [date] => 2012-10-18 [project_id] => 0 [project_num => 49 [task_desk] => This is a task [hours] => 3.30 ) But when I use echo to output the $aCard array and then try to break it down inside the success function of the ajax call, I can't figure out how to get at the values. My attempts have consistently returned values of "undefined". In the success function, in place of alert(data);, I've tried this: var tce_staff_id = data['staff_id']; alert(tce_staff_id); and this: var tce_staff_id = data.staff_id; alert(tce_staff_id); What am I missing? UPDATE: Thanks to Martin S. for information re json_encode() PHP instruction. I've modified the ajax script as follows: echo json_encode($aCard); I now get THIS result from alert(data); in the success function: {"staff_id":"51","date":"2012-10-18","project_id":"0","project_num":"49","task_desc":"This is a task","hours":"3.30"} However, the following returns "undefined": alert(data.staff_id); alert(data[0].staff_id); var test = data.staff_id; alert(test); Can anyone see what I'm missing? All above code comes immediately after alert(data) inside the success callback of the ajax function. alert(data) DOES work and displays the desired data, as above.
