  • How can I shut down all my Virtual Machines when my UPS kicks in?

    - by Tim
    I have a Dell T610 running ESXi4, an APC Smart UPS 1000VA and a local "console" machine running Vista and the vSphere 4 Essentials pack. A dedicated management network is in place between the T610 and the Vista machine. We have 4 VMs: SBS 2003, Server 2003 running Terminal Services, and two XP Machines. Ideally, when the UPS is forced to use battery power [for a set number minutes], I would like to gracefully shutdown all the VMs, then the ESXi, then the console machine. The latter two are not strictly a priority, but the VMs within ESXi are. Google provided lots of deprecated scripts that used to work on ESXi 3.x or similar, however I am unable to find what they were deprecated by. What do I need to be able to do this? I have Powerchute Express as supplied with the UPS, but would be willing to pay for software if required.

  • How can I install iTunes in such a way that it can't put any "hooks" or helper programs on my computer?

    - by Joshua Carmody
    I'm buying a new iPad, which means I must once again install iTunes. I've not used iTunes in more than 6 months, since I bought a new computer. I don't like iTunes, but I can live with using it to buy/manage media and sync my Apple devices when the program is open. What I would like to do though, is find a way to install iTunes in such a way that it has absolutely no effect on my system when it is closed. iTunes normally installs several helper programs such as iTunesHelper.exe, and the Bonjour service. These programs run in the background when iTunes is closed. You can force-close them, or remove them from your setup files, but iTunes will often put them right back when you run it. I know these programs are mostly harmless, but they have at times caused issues such as iTunes spending system resources trying to catalog media files or drives connected to VPN, or other issues. At best they're just one more small background process eating up a small piece of my CPU time and RAM. How can I run iTunes without letting it get it's "hooks" into my system? One thought I had is that I could create a Windows user account just for iTunes, and deny it admin privileges. Then if I installed iTunes using that account maybe anything it installed wouldn't affect the "main" account on my PC? But I'm not sure if that would work.... Failing that, maybe some kind of virtualization software or sandbox I could install it in? I'm open to any suggestions. My system is an Intel-based PC running Windows 7 Professional 64-bit. Thanks!

  • Windows shutting down, CPU maxing out in Windows-7 32-bit? [closed]

    - by Vivek Sharma
    I have no idea, what is happening to my laptop. For last 5-6 times it has automatically shutdown while running, without doing anything serious. And I even do get the message during boot which says - Start windows normal - Start in safe mode It just boots up normal. Few days ago, my screen blinked and it the PC shutdown immediately. After that I was not able to get it started. I got it repaired, the guy said he has replaced the display chip (nVidia-nvs-140), but i seriously doubt that. Now it started working, but would shutdown every 20 mins or so. I have a dual boot, ubuntu-11.10 works just fine. Virus scan on windows shows nothing. I am pasting my perfmon output. My CPU for reason is maxing out to 100% continously, for windows internal processes. Please have a look at the attached file. Strangly now for last 2 hours it is working fine, but i am just writing emails and reading excels. ThinkPad T61 | t9300 | 3gb | nVidia 140 nvs-quadro (latest driver 296.10) What do you suggest?

  • Why do servers go down after a lot of traffic?

    - by mohabitar
    I'm working on an iOS app that makes extensive use of databases, where users will be able to sync their data to a server. However, I'm terrified of the event that if too many users start using the app, the servers will no longer be able to handle it. I'm not a server guy at all and am not too familiar with how that works, but my question is, why do servers get overloaded and how can that be prevented? Does it have to do with who my server host is? Or is it about the efficiency of my code? If my host is a reliable server, such as Amazon AWS, am I still at risk for server problems? Bottom line is, does it have to do with the way I implement my code, or does it have to do with who my host is?

  • Startup Folder, HKCU/.../Run, HKLM/.../Run. Where Else to Look to Track Down a Mysterious Login Even

    - by Bob Kaufman
    Starting around the time I installed the Office 2010 Beta, Whenever I login, Windows tries to open a file named "Bob", coincidentally the first part of my username. Selecting Notepad to open it, and it contains TCP/IP network settings. I've looked for and deleted unrecognized entries in my StartUp folder, in HKLM/.../CurrentVersion/Run and in HKCU/.../CurrentVersion/Run with no luck. Is there any other place I should be looking for errant entries?

  • How do you close a VMWare Fusion VM Window without shutting it down or suspending it?

    - by Chris
    There are a few parts to this question. The first is: I'm running a virtual machine guest using vmrun and nogui, when I open the VMWare Fusion application, the window library opens but subsequently also opens any window of a running VM. Is there a way to prevent this? Secondly, but related: Once it does pop up or I have that separate VM Window open, is there a way to close the window such that it does not suspend or shutdown the vm i.e. convert it back to nogui mode?

  • Computer hangs at BIOS screen. Cannot enter setup.

    - by d2jxp
    I have an HP Pavilion a6500f (it's a year out of warranty) and it's hanging on the blue HP BIOS screen. If I mash F10 while it's starting up, it will say "Entering Setup..." but I will see no results. It will hang there and not do anything. If I actually wait until I can see the screen and then hit F10, there's no response at all and the computer will sit at the BIOS menu. I've dusted and cleaned it out, reseated the memory, switched the RAM slots, and reset the CMOS battery using the reset jumper. I'm out of ideas. I'm pretty sure it's not a hard drive issue, since my problem is at the BIOS. After this post, I'll disconnect the hard drive and try to just boot without it. Anyone have any other ideas? Edit: Okay, so I tried disconnecting the hard drive and now I can get back into the BIOS. I reconnected it and I'm locked out again. So the problem is my hard drive.. I guess I should delete this post unless someone has any ideas as to what's wrong with the drive?

  • Who should I run mysql as, on a personal computer?

    - by user664833
    I just installed mysql via homebrew (with brew install mysql, on Mac OS X Mountain Lion - recently installed from scratch). Following the installation, there is a "caveats" section with options around further necessary actions to take: ==> Caveats Set up databases to run AS YOUR USER ACCOUNT with: unset TMPDIR mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp To set up base tables in another folder, or use a different user to run mysqld, view the help for mysqld_install_db: mysql_install_db --help and view the MySQL documentation: * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html To run as, for instance, user "mysql", you may need to `sudo`: sudo mysql_install_db ...options... Start mysqld manually with: mysql.server start Note: if this fails, you probably forgot to run the first two steps up above A "/etc/my.cnf" from another install may interfere with a Homebrew-built server starting up correctly. To connect: mysql -uroot To launch on startup: * if this is your first install: mkdir -p ~/Library/LaunchAgents cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist * if this is an upgrade and you already have the homebrew.mxcl.mysql.plist loaded: launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist cp /usr/local/Cellar/mysql/5.5.27/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist You may also need to edit the plist to use the correct "UserName". On previous versions of Mac OS X I ran mysql as mysql user, but now I am confronted by the idea of running it as myself. I am the only one who uses this computer (which happens to be my laptop), and I do programming for work and for pleasure. What are the pros & cons, or best practices, around choosing whether to run mysql AS YOUR USER ACCOUNT or as mysql or something else still?

  • Proper configuration for Windows SMTP Virtual Server to only send email from localhost, and tracking down source of spam emails

    - by ilasno
    We manage a server that is hosted on Amazon EC2, which has web applications that need to be able to send outgoing email. Recently we received a notice from Amazon about possible email abuse on that server, so i've been looking into it. It's Windows Server Datacenter (2003, i guess), and uses SMTP Virtual Server (you know, the one that requires IIS 6 for admin). The settings on the Access tab are as follows: - Authentication: Anonymous - Connection: Only from 3 ip addresses (127.0.0.1 and 2 others that refer to that server) - Relay: Only from 3 ip addresses (127.0.0.1 and 2 others that refer to that server) In the SMTP logs there are many entries like the following: 2012-02-08 23:43:56 64.76.125.151 OutboundConnectionCommand SMTPSVC1 FROM: 0 0 4 0 26364 SMTP - - - - 2012-02-08 23:43:56 64.76.125.151 OutboundConnectionResponse SMTPSVC1 250+ok 0 0 6 0 26536 SMTP - - - - 2012-02-08 23:43:56 64.76.125.151 OutboundConnectionCommand SMTPSVC1 TO: 0 0 4 0 26536 SMTP - - - - 2012-02-08 23:43:56 64.76.125.151 OutboundConnectionResponse SMTPSVC1 250+ok 0 0 6 0 26707 SMTP - - - - ([email protected] is sending quite a lot of emails :-/) Can anyone confirm if the SMTP server settings seem correct? I'm also wondering if a web application on the machine could be exposing a contact form or something that would allow this sort of abuse, looking into that (and how to look into that) further.

  • Why does my computer sometimes not identify my wireless network, or others, that it always connects to?

    - by Emile Erasmus
    I have a vista operating system. Sometimes my computer will not connect to the wireless network (internet) when I start up my laptop. This happens at different places on occasion, and it is very random. It tries to connect, but can not identify the network (it does recognize the wifi name). So at the end it connects, but with limited connectivity. It can not be the hardware because all other computers connect to it fine at the same time. And it happens at different places, mostly home, but sometimes at coffee shops, etc. And then in a day or two when I start up my laptop it is all of a sudden working again. (restart does not solve the problem). I have tried all the trouble shooting options windows offers, restarting the notebook, switch modem on and off, switch laptop wifi on and of, deleted the wifi memory from the laptop and reconnected with the password as if it was the first time, everything. If it does not work at one place it does not mean it won't work at another. Example it won't work at home, then I go to coffee shop and it works, then get back home and it don't. Anyone encountered this before?

  • one of my web hostings is down - only for me - why ?

    - by Thomas Traub
    My first post here, I am reading / learning a lot, thanks ;). I've got a mysterious issue (for me) and would really appreciate to get it solved. I've rent a reseller package with bibihost.com and it's now the second time that all my domaines the hoster's site are unavailable from my connection (my Mac and my iPhone), (in browser, per FTP, ping, ab, and traceroute) This has never before happened to me with other web addresses. traceroute get's always stuck at a specific server 40g.vss-1-6k.routers.chtix.eu (91.121.131.29) The sites are all up for everyone else, I've checked with downforeveryoneorjustme.com, a homegrown script loaded to another server and montastic.com My question(s) : Why am I blocked ? Is there anything I can do about it ? If I cannot solve this issue I have to change the hoster, but I really would like to know what's going on. my domaines on this server : tienstiens.fr tomlegrand.com

  • Why is my computer randomly restarting? How can I fix it?

    - by kinglime
    I have a custom built desktop computer that I've been using since about a year ago. The main specs are: ASUS P8Z68-V LE Motherboard Intel Core i7 2600k Corsair Vengeance 16GB Ram ASUS ENGTX570 GPU Corsair TX650M PSU I was running an overclock of 4.4ghz for my cpu (I have a Hyper212 EVO) and 1600mhz for my RAM but have it currently turned off due to my issues. I am also currently running Windows 8 but this problem occured in Windows 7 too. Basically my issue is that seemingly randomly, with no pattern my PC will reset itself and ASUS Anti-Surge will alert me that something went wrong. This issue is not related to system stress. I can run it fine for an hour maxxed out on Prime95 then later I can be watching a mere YouTube video when it will randomly reset. This has been occurring probably for the last two weeks and it seems to be getting worse. I believe this might be related to the power supply but when I monitor it in the bios and in Windows it appears to be putting out the proper voltages. Also possibly related or not but my Nvidia drivers frequently temporarily fail and then warn me of some kind of kernel error? If I have to buy a new power supply that is what I'll do but I want to make damn sure that's the only issue at hand. Thank you everyone in advance, please help me diagnose the issue and tell me what I can do to fix it. If you need any additional info about my setup please ask me.

  • Dns server: how can I configure a dns server to track down a pc name in a dhcp enviroment?

    - by Pitto
    I have a dhcp in my home and I would like to setup a dns server too. I would like to implement a linux solution but I think I can't get hands on without understanding - very superficially - if I can achieve such result. My pc (hostname: test) gets a 192.168.1.7 from dhcp. Its dns server is my router (192.168.1.1). How can the router relate my ip change (as soon as the lease is over) to my hostname?

  • Should I buy more RAM for my computer or a better CPU?

    - by Reijer The Coder
    I have recently bought a new laptop, an ASUS N56VJ-S4149H. I bought it to use it in all possible ways I could want, so that would be gaming downloading and streaming movies browsing the web and programming software. So far it has been running great but one thing annoys me a little bit. I frequently play Mount&Blade: Warband, it's a great game and you should check it out. Everything runs smoothly but only when I turn down the 'Texture Detail'. Otherwise it will lag a lot and I can't really play. Now my question is: Is this a problem of not enough RAM? At first I was really sure it was but after thinking about for a while I'm not anymore. My computer only has 4 Gigabytes of RAM and there is still a slot open. So will it improve when I buy another 8 Gigabytes? EDIT: It has an Nvidia GeForce GT 635M inside. and an Intel Core i5 3230M CPU with 2,6 GHz. Help and answers are really appreciated. Thanks to all.

  • AWS instance went down for restart, came back up and has been "Waiting for network configuration... " for 12 hours

    - by kavisiegel
    What happened was about a month ago, I created a new instance, re-configured everything, and mounted the old instances drive to the new one. I then detached the old drive from the instance, but it was still mounted, so it errored out. Now, come the outage last month, and when the instance boots back up - the drive isn't there, because in the downtime, it dismounted. It hangs because the fstab is looking for it. I get word that the server's not up today, I check the logs, re-attach the drive and restart. Now I'm getting "Waiting for network configuration..." and it doesn't seem to be doing anything. Some googling told me that I'm going to need to start from zero again, which I don't think is right. I created a new instance, which booted no problem, then I stopped it and swapped the two old drives into the new instance. Still the same error. Using the fresh AMI, it worked. I figure it's just a misconfigured Amazon file. I can attach the drive to a functioning instance on the same AMI and copy some files over, then try again - but I don't know where to even start or what files to check.

  • Is it possible to track down who or what changed a shared permission?

    - by user45574
    Today I received an email from one of my users asking why he couldn’t access his shared folder on one of our servers. Example: \\servername\share\ = access denied. When I checked the share permissions on the folder I was surprised to see that the user had been removed from the "shared permissions" list. Now my question is: Is it possible to track who or what deleted the users share permissions on the folder? I have studied the different event logs, but couldn’t find any indication of anyone who had changed the share permissions. Kind Regards Martin

  • Application got shut down in WinXP if I close the 2nd window of that application.

    - by kinopyo
    I'm using WinXP and here is my question: I run an application, such as Chrome, there would be one app in the task bar, and it's fine. Suppose a new window of Chrome opened(so there would be 2 window and 2 in the task bar), and when I close that,the 2nd one, the whole application just shutdown. And so does chrome, firefox, evernote, Becky!(the email client), even TortoiseSVN. So I think there should be a generic problem cause these applications shutdown, such as the platform - WinXP. Please give me some advice or hint, anything comes to your mind would be helpful!

  • Which scripting language to use to asynchronously ssh into equipment, run several commands, parse the output, and save to a file on my computer?

    - by Fujin
    There are several points I'd like to stress in my question. I'd like to login by asynchronously ssh'ing into our infrastructure equipment. Meaning, I do not want to connect to only one device, do all the tasks I need, disconnect, then connect to the next device. I want to connect to several devices at once in order to make the process as fast as possible. By equipment I mean 'infrastructure equipment' and not servers. I say this because I will not have the luxury of saving files to the device then transferring them to myself with scp or another method. The output of the scripts that are run will have to be saved directly to my computer. The output of the commands that are run will need to be cleaned up and parsed. Also I want the outputs of each device to be combined into one nice and neat file, not a separate file for each device. This will all be done from a linux box, using ssh, into devices that all use linux'ish proprietary OSes. My guess is the answer to my question will either be a Bash, Perl, or Python script but I figured it wouldn't hurt to ask and to hear the reasons why one way is better than another. Thanks everyone. EXTRA CREDIT: With you answer, include links to resources that will help create the script I described in the language that you suggested.
