  • nagios service check

    - by DRH
    I am new to nagios and we have a small issue I need to ask assistance with. Many of the machines that we monitor can go unresponsive for a bit when some very intensive cpu tasks are run. This makes nagios send warnings and alerts while these hosts are busy reporting things like 'ping timeout' or 'zombie processes' and even swap space warnings, but in actuality there is not a problem. Is there a way to configure nagios to not send such alerts, but check x number of times over a period of time and only then send an alert at the end of that time if the server in question has not recovered?. Looking at the commands.cfg file, I see entries like this: define command{ command_name check_local_swap command_line $USER1$/check_swap -w $ARG1$ -c $ARG2$ } How could I modify this example to accomplish what I want above. Thanks

  • Apache logging: rotating logs on Win32?

    - by Jason S
    I was noticing my disk space disappearing faster than expected, and finally narrowed it down to a rewrite.log file that was 4 GB in size! Is there a way to rotate the various Apache logs (rewrite, error, access, etc.) on a Win32 PC so that only the most recent entries are there and I can limit the data size that results? I found the bit about log rotation on Apache's website but it's Unix-centric. Edit: I got rotatelogs.exe to work, and it's great except that it slows the server response down noticably so I rejected the idea of using it.

  • Windows XP occasionally hangs for 2-3 minutes as the splash screen fades in.

    - by marcusw
    This is a bit of a rare problem, I have not been able to debug or fix it or find anyone else with the issue. I hope someone here can help me out. Once in a while, I boot up Windows XP from the first partition of the first disk (using grub, the computer dual-boots ubuntu) and it hangs as the Windows XP splash image fades in, leaving the screen with a dim image of the splash screen. After 2-3 minutes, it continues to boot as normal, no error messages or strange behavior. I have noticed that this happens about 75% of the time when the last time the computer was shut down it was from Ubuntu, and maybe 5-10% of the time otherwise. I have looked at system logs as far as I was able, and did not find anything the miss. What is causing this and how can I fix it?

  • Missing Desktop Icon Labels in Windows 7

    - by Buzzedword
    Hey guys. Big problem that has been bothering me to no end. My desktop icons have been stripped of their icon labels, and nothing seems to be recovering them. To be clear, when I attempt to rename, the text shows up, and when I view my desktop in an explorer window, all text is preserved. System restore to a stock state will not recover. No changes have been done to the computer-- no installs or downloads for two weeks prior to this error. Rebuilt the icon cache, still no response. Anybody know what can be causing this problem? Screenie below. Thanks in advance. OS: Windows 7 Enterprise 64-bit Profile: Local, non-roaming Image: http://img688.imageshack.us/img688/5152/capturemr.png

  • Filemaker show total from related table

    - by Mr_Chimp
    I have a bit of experience with Access and SQL but I'm new to Filemaker. I have a layout which shows a list of projects. One of the fields I want it to show is "total amount of paid invoices up to the end of the last financial year". The invoices are stored on another table so I will need to pick from this table all records where "project id" = "project id" (this is set up as a relationship between the tables) and also "invoice is paid" = yes AND "date invoice paid" < start of last financial year. My question is how do I go about getting and showing that data? I can get a total easily enough, it's filtering out these specific rows that I'm having trouble with. I'm guessing there's an easy solution...

  • Logitech SetPoint update seems to be hanging

    - by Rod
    I've just gotten a new Logitech Wireless Wave Combo MK550 mouse and keyboard. I pulled it in, and have installed the software that came on the CD, which is SetPoint 6.15. After installing it, it said that it had an update, so I started the installation for that. Now it's at a point where it says, "Approximately 30 second remaining...". It has been that way for 30 minutes, not 30 seconds. So, what's going on? I'm installing this on a Windows 7 Home Premium system, 64-bit OS.

  • How do I check if a process (Firefox) has quit?

    - by Al_Jehle
    I am using Ubuntu 12.04 64-bit, with all updates installed. I made a simple shell script that starts a SOCKS5 tunnel and launches Firefox (with correct network proxy settings) to use the tunnel. How do I recognize when Firefox has ended (when I close it) so that I can close the tunnel? Also, it would be awesome if I could run this in the background, but not necessary. #!/bin/sh ssh -fCN -D 10000 server.com firefox //To lauch firefox using Ubuntu ? Code to determine when firefox has quit Code that kills the tunnel

  • My images look desaturated and brighter on the iPhone than on my Mac (in PS, Pixelmator & Finder)

    - by david
    I save my image in Photoshop (No Color management). I put it on the iPhone and it looks brighter and desaturated. Also my blue-green looks more like blue. I have tried some color profiles on the net: http://luminous-landscape.com/forum/index.php?showtopic=38121 http://www.colorwiki.com/wiki/Color_on_iPhone But the images still look different. I'm going insane with this because its stealing my time away and i can't fix it. Every bit of help would be appreciated! Do I have to create my own profile? Is there an easy way??

  • Trying to figure Windows 2008 Server and Active Directory - complete novice!

    - by Simon E
    I am a novice in networking and I want to learn more about Windows Server 2008 and Active Directory. Basically I have serveral Windows 7 PC's in my home and an IBM server with Win Server 2008 installed. I have enabled Active Directory and set the server to have a static IP. Thats as far as I have got and I feel a little overwhelmed at the moment as I am not sure what to do next. What I eventually want to do is have the Windows 7 PC's to be able to be authenticated by the server - basically a mock up of what most large or medium sized businesses/organisations run. Sorry if I sound a bit sketchy, but I understand some things but not the whole picture, I guess I just need confirmation that I am sort of on the right track :) Also what are some good resources out there you can point me to, what are the absolute basics I need to to get started so I can further my learning?

  • Windows 7 hangs after longer inactivity of user

    - by scooby37
    I have serveral PCs running Windows 7 in different falvors (32- / 64-bit / Professional / Ultimate / ATI / Nvidia) - they all have one problem in common... ...if I don't work on any of them for a longer time and the screen goes off as it should be (all default settings!) they sometimes go into some kind of sleep mode where I get to see the desktop or whatever I did before leaving after moving the mouse or pressing a key - but nothing reacts for a different amount of time from serveral seconds to serveral minutes! Any hint that helps solving this anoying problem would be very welcome ;-)

  • Associate a texture to an object (from a data-model, not graphical point of view).

    - by Raveline
    I'm writing a roguelike where objects and floor can be made of different materials. For instance, let's say we can have a wooden chair, an iron chair, a golden chair, and so on. I've got an Object class (I know, the name is terrible), which is more or less using a composite pattern, and a Material class. Material have different important properties (noise, color...). For the time being, there are 5 different instances of materials, created at the initialization of the game. How would connect an instance of Object with one of the 5 instances of materials ? I see three simple solutions : Using a pointer. Simple and brutal. Using an integer material-id, then get the materials out of a table when engine manipulates the object for various purposes (display, attack analysis, etc.). Not very beautiful, I think, and not very flexible. Using an integer material-id, then get the materials out of a std::map. A bit more flexible, but still not perfect. Do you see other possibilities ? If not, what would you choose (and why) ? Thanks in advance !

  • Apache RewriteRule ignoring RewriteCond?

    - by winsmith
    So I have an Apache running on OSX Server 10.4 (don't ask) with multiple sites. In 0002_[example.com].conf, I have this bit of code: <Directory "/Library/WebServer/Documents/secret/"> RewriteEngine On RewriteCond %{REMOTE_ADDR} !^137\.250\. RewriteRule .* /messages/secret.html </Directory> However, in this configuration, the RewriteCond always seems to evaluate to false, since the secret directory gets shown even if the client's address does not begin with 137.250. If I change the config to this <Directory "/Library/WebServer/Documents/secret/"> RewriteEngine On RewriteRule .* /messages/secret.html RewriteCond %{REMOTE_ADDR} !^137\.250\. </Directory> the condition either does not get evaluated at all or always evaluates to true. Either way, all clients get blocked. What am I doing wrong?

  • Public domain usage of imagery from films? [on hold]

    - by AdamJones
    I'm thinking of starting a small film site, which would begin as a simple blog. Imagery from films I discuss on the site would be vital to the look and feel of this site. Instantly though this makes me wonder about copyright/public domain rights for such imagery. I just wondered if anyone had general or specific advise about using imagery from this industry or another similar situation? On the one hand I know the film industry aggressively tries to protect its IP (fair enough), but on the other hand, surely film companies do release some imagery of their films in stills format into the public domain to simply help their distribution and advertising efforts? I have tried looking on stock photo galleries for images of film stills but only found moviestillsdb.com) which seemed very limited in its results. I've researched a bit about fair usage (http://fairuse.stanford.edu/overview/fair-use/) as well, which I know applies to the USA specifically. This seems to suggest that a still of a film is within these bounds. Still, any constructive advise others may have as a result of experience dealing with imagery, from film or another domain would be greatly appreciated, assuming it isn't "get a lawyer".

  • How to block a website completely?

    - by user37076
    I want to block some sites(e.g. youtube,news sites ), because I have a problem with procrastination and I find these websites affect my productivity very much. I used to block them by adding them to HOSTS file. However, gradually every time I want to take a break, I open the hosts file and comment my block again. Is there any way I can block the websites and cannot (at least a little bit hard, e.g. I have to reboot my pc) unblock them. I have no access to the router or any firewall, besides the ones on my computer. I just want to FORCE myself to work without any chance to procrastinate.

  • Redirect websockets to port?

    - by DigitalMan
    So, I've got a WebSocket server in C++, that is a completely stand-alone entity - handles header parsing, receiving, sending, all of it on its own, listening directly to the port. Problem is, it needs to run on a server alongside Apache, and that's a bit of a problem. Now, there was a solution here to a similar issue involving mod_proxy, but I'm hoping I can intercept and redirect WebSocket communication before Apache even knows about it, possibly with iptables. So the question is, is it possible to direct traffic bound for chat.mysite.net to a WebSocket server on, say, port 8080, while anything else headed to mysite.net proceeds as expected to Apache?

  • Series On Embedded Development (Part 1)

    - by user12612705
    This is the first in a series of entries on developing applications for the embedded environment. Most of this information is relevant to any type of embedded development (and even for desktop and server too), not just Java. This information is based on a talk Hinkmond Wong and I gave at JavaOne 2012 entitled Reducing Dynamic Memory in Java Embedded Applications. One thing to remember when developing embeddded applications is that memory matters. Yes, memory matters in desktop and server environments as well, but there's just plain less of it in embedded devices. So I'm going to be talking about saving this precious resource as well as another precious resource, CPU cycles...and a bit about power too. CPU matters too, and again, in embedded devices, there's just plain less of it. What you'll find, no surprise, is that there's a trade-off between performance and memory. To get better performance, you need to use more memory, and to save more memory, you need to need to use more CPU cycles. I'll be discussing three Memory Reduction Categories: - Optionality, both build-time and runtime. Optionality is about providing options so you can get rid of the stuff you don't need and include the stuff you do need. - Tunability, which is about providing options so you can tune your application by trading performance for size, and vice-versa. - Efficiency, which is about balancing size savings with performance.

  • Windows 7 network share issues w/XP & SBS 2K3

    - by Kevin K
    Hi, my Windows 7 Ultimate 64 bit computer has issues when accessing SBS 2K3 or XP shares. 1) It will not automagically reconnect upon boot. I have a batch file that will do this that utilizes net use (yes I have /persist:yes, but it does not help) to re-map them. 2) After trying to use it for a few minutes, it will not work. Any attempt to access the drive letter that was mapped causes windows Explorer, or other apps. to lock up. These shares work fine from XP & Vista computers. When this happens the internet works fine, just the mapped drives do not work correctly.

  • Why won't Windows XP 64 install on my machine?

    - by user272671
    I have a hp xw8200 workstation and would like to install Windowx XP 64 bit on it. Problem I seem to be having is when I reboot the machine and try to boot from the CD, nothing happens. Seems that the CD Drive is not being located or does not execute my cd to start the install. I already checked to verify that I can install Windows XP 64bit on my machine and also ensured I have the right bios and drivers for the install, only that the boot just does not take place. Anyone have any idea how I can solve this problem ? http://www.hp.com/workstations/pws/xw8200/xw8200.pdf http://h20331.www2.hp.com/Hpsub/cache/286710-0-0-225-121.html http://h20331.www2.hp.com/Hpsub/cache/286707-0-0-225-121.html thanks in advance

  • SCCM - How to make new deployed applications appear in Software Center faster?

    - by icehac
    I am trying to make the process between SCCM deployments and the Software Center (configmgr) faster, if not seamless. Right now, applications generally take about 1-2 hours to populate properly. However, by going to the "Configuration Manager" under the Windows Control Panel, there is an "Actions" tab. Generally 5 minutes after running these "Actions", the software will populate inside the Software Center. The downside of this is the user interaction with the "Actions" pane...I can't have a user going through this process when they request a new application that needs to be deployed through SCCM. I have have played around with using "net stop ccmexec" and "net start ccmexec" to manually run all of these "Actions" on the start command, but it feels a bit archaic. Does anyone have any suggestions how to speed this process up? I feel there is something simple I am missing.

  • Installing Ubuntu on HP Envy 4 - 1104tx (preinstalled Windows 8)

    - by Froyo
    I have been using Linux for more than 2 years now. I had hp pavilion dv4 laptop and Ubuntu 12.04 was working great. I recently purchased HP Envy 4 - 1104tx which has Windows 8 preinstalled. I tried to install Ubuntu 12.04 but since it is not much compatible with UFEI, I downloaded 64 bit iso of ubuntu 12.10. Made a liveUSB using UnetBootin 583. I followed Installing Ubuntu on a Pre-Installed UEFI Supported Windows 8 system but still I am not able to boot with LiveUSB. I disabled secure boot. There is no option for fast boot or anything as such. It still wouldn't work. I also tried booting through Legacy, but I'm unable to install via LiveUSB. Is there any other way? I don't have SSD so no problem of fake raid. Is there some way by which I can install Ubuntu (12.04 preferred)? I don't care about Windows 8. Is there any way via which I can install Ubutnu over Windows 8? (I don't have a CD/DVD ROM).

  • Secondment promotion promises

    - by user75460
    I'm a Java developer at a large FTSE 30 company. My line manager approached me and asked if I'd like to be the teams lead developer. I was keen to accept. Initially he said I'd be acting-up for 3 months, then changed his tune and said I would be doing a 6 month secondment. During this time, he has got himself promoted and I have a new line manager. I have been very successful during this secondment and reviews have been overwhelmingly positive: both from my former line manager and current line manager. However, six months on, no lead role has been created in the organization and a new director has re-organised the structure of the team: two senior roles (senior Android and senior iOS) are going to be created. I feel a bit put-out that my secondment has amounted to nothing. I could have just done nothing and then applied for the senior role 6 months later (which I feel aren't as marketable as Lead developer). During my secondment I have basically become TA, senior developer, line manager and general go-to guy for all things (across Android and iOS). What do you think I should do, and has my company abused it's position? I feel they have offered a secondment to a role that they never really planned to create. During this time I have received no financial benefit for doing a more senior role.

  • Acer Aspire 7750-6801 windows 7 Home Premium x64 not charging properly [closed]

    - by MaurerPower
    I have an Acer Aspire 7750-6801 laptop running Windows 7 Home Premium 64 bit OS. The issue is that it will only charge sometimes when plugged in. I thought it might be a hardware issue, so I tried charging with the laptop off, and it works fine. Also when in Linux, or any other environment other than Windows, it also charges fine. The intermittent charging issue ONLY presents itself when in Windows. I've tried the following: Open Device Manager Under 'Batteries->', I uninstalled 'Microsoft ACPI-Compliant Control Method Battery' Then re-installed using 'Scan for hardware changes' Still no luck. It's quite urgent, any help would be appreciated as I am totally at a loss...

  • Xubuntu 12.04: Slow Login

    - by naxchange
    I'm running Xubuntu 12.04, and after I ran the update, my login started slowing down big time. I've dabbled a little bit with the programs in Settings - Settings Manager - Session and Startup, and tried closing and opening these programs, and then rebooting. Anyways, I narrowed it down to a combination of 2 processes, "Network" (the connection manager) and "Xfce Volume Daemon". Their corresponding terminal commands are: ~$ nm-applet ~$ xfce4-volumed If I disable them, and then run them after login is complete, everything works just fine. Is there a way for me to run these commands automatically at start up? I want to maybe write a shell script and save it somewhere, or at least edit the order things happen after login, so the desktop can load before these processes. Hope I've been clear enough, and thanks in advance! NAX

  • Strings are UTF-16&hellip;. There is an error in XML document (1, 1).

    - by Shawn Cicoria
    I had a situation today where an xml document had a directive indicating it was utf-8.  So, the code in question was reading in the “string” of that xml then attempting to de-serialize it using an Xsd generated type. What you end up with is an exception indicating that there’s an error in the Xml document at (1,1) or something to that effect. The fix is, run it through a memory stream – which reads the string, but at utf8 bytes – if you have things that fall outside of 8 bit chars, you’ll get an exception.   //Need to read it to bytes, to undo the fact that strings are UTF-16 all the time. //We want it to handle it as UTF8. byte[] bytes = Encoding.UTF8.GetBytes(_myXmlString); TargetType myInstance = null; using (MemoryStream memStream = new MemoryStream(bytes)) { XmlSerializer tokenSerializer = new XmlSerializer(typeof(TargetType)); myInstance = (TargetType)tokenSerializer.Deserialize(memStream); }   Writing is similar – also, adding the default namespace prevents the additional xmlns additions that aren’t necessary:   XmlWriterSettings settings = new XmlWriterSettings() { Encoding = Encoding.UTF8, Indent = true, NewLineOnAttributes = true, }; XmlSerializerNamespaces xmlnsEmpty = new XmlSerializerNamespaces(); xmlnsEmpty.Add("", "http://www.wow.thisworks.com/2010/05"); MemoryStream memStr = new MemoryStream(); using (XmlWriter writer = XmlTextWriter.Create(memStr, settings)) { XmlSerializer tokenSerializer = new XmlSerializer(typeof(TargetType)); tokenSerializer.Serialize(writer, theInstance, xmlnsEmpty); }
