  • KVM graphical tools and employment

    - by Recursion
    I saw a job classified asking for a Linux admin who could administer KVM based vm's. I can do so if I use virt-manager or some form of graphical tool, but I'm not really familiar with all of the command line material. I also cant really find a good tutorial on it, as most sites say to use the graphical stuff. My question is, for a position like this is my understanding satisfactory to apply?

  • Disk Image Tools for Windows Server 2008

    - by Jon Rauschenberger
    I have a Windows Server 2008 X64 machine that I need to swap the boot drive on. I'd like to use a disk image/restore utility to make an image of the boot partition and restore that to the new drive. Does anyone know of a free or reasonably priced tool that can do this? I know that Acronis True Image will do it, but you need to have their server product to restore images of a server OS and it's prohibitively expensive ($850). Thanks, jon

  • Recommendations for secure business collaboration tools

    - by Michael Prescott
    I'm searching for a secure and easy way for business partners to collaboratively edit and exchange documents, share calendars, create schedules, and assign tasks. I speculate that the ideal collaboration environment or work-flow would actually involve several technologies and services. My co-workers and I have tried a variety of things from Google Apps to Wiki's, but nothing feels very fluid or complete. I suppose defining what we need and our constraints is probably in order: collaboratively edit basic text documents and spreadsheets exchange documents like flow-charts, graphs, and files generated by our other desktop applications, but not source code assign tasks to each other and ourselves and track the history of those tasks easily see when relevant documents have been modified since last viewing and ability to easily push notifications to relevant workers (a clean front page that shows updates would probably suffice) provide limited access to contract workers and guests users if a remote user system is compromised (keystroke logger or other spyware) we don't want the criminal to be able to gain access to all business documents (processes, trade-secrets, customer lists, etc.) simply because they gained access to a single Google account (or whatever web service) Cannot be a difficult to administer VPN infrastructure Cannot cost more than $100 per month (yeah, money is tight) Needs to support up to 25 users We can host our own web applications, but it must be low maintenance solution

  • Tools for retrieving and modifying multi-value attributes in Microsoft ActiveDirectory

    - by Justin
    Most attributes in MSAD are single-valued and pose no problem. I am familiar with the dsquery user -samid jdoe | dsmod -webpg "http://some.url/" method. However, some attributes are multi-valued, such as telephone number and webpage. These values can be managed through the Active Directory Users & Computers Microsoft Console (dsa.msc) via the dialogue shown by clicking on the "Other..." button, but I'd really rather script the modifications. It seems to me that dsmod & dsget do not support multi-value retrieval and editing; only the first value of the set seems to be accesible. Am I correct? If I am not correct, I would appreciate a syntax example. If I am correct, would you please recommend an alternative scriptable tool that can handle multi-value attributes? The more "official and supported" the tool, the better.

  • Good PC-based video conference control tools?

    - by Jeremy Wadhams
    I'm looking to improve the user experience in our video conference rooms, by simplifying the things users do all the time (setting up a call, muting and unmuting, panning and zooming between a few room-appropriate presets) and totally taking away the functions that we don't use or that are more likely to ruin the experience (changing the brightness of the TV, using the VNC presenter mode). The rooms each have Tandberg Edge or MXP video units, I'm not looking at PC-based solutions like Skype or iChat. The classic way to do this would be to plunk down huge money for an AMX or Crestron panel. This does have some advantages, and I am considering that approach, but in my initial investigation, that looks expensive, inflexible, and proprietary. On the other hand, the Tandberg video units I'm looking to control are very thorough XML API (PDF), so some of the integration magic that Crestron and AMX consider to be a value add, I could reproduce at mashup speeds. Anyone aware of an Open Source or Commercial product that takes advantage of the readily available web APIs, some simple touch screen PCs, and builds a product that is more like skinning an AJAX web app, and ideally more cost effective than the proprietary panels?

  • [Zend Debugger] Cannot receive start command

    - by tharkun
    Hi I have a WAMP install (Apache 2.2.3, PHP 5.2.8) with a working Zend Optimizer. As soon as I add the php.ini lines for Zend Debugger: [Zend Debugger] zend_extension_manager.debug_server_ts="C:\zenddebugger" zend_debugger.allow_hosts=127.0.0.1/32, 192.168.0.0/16, 192.168.1.0/255 zend_debugger.expose_remotely=always and restart apache, I get a blank page and the following entry in the apache error log. [Zend Debugger] Cannot receive start command [Zend Debugger] Cannot send message Now the incredible thing is that I had it working this morning and now, after reinstalling WAMP there is no way I can get it work again. php.ini is exactly the same as it was before. I would be extremely glad to get help, I'm trying to get a working server environment going for over a month, can you believe that? I tried XAMPP, Zend Server and now WAMP and I'm going crazy slowly but surely.

  • Standalone firewall + antivirus or combined security tools?

    - by pukipuki
    For years I'm using some antivirus software and different firewall. Now every antiviruses have got some firewall features and there are complete "internet security" complexes... and every firewall get some antivirus functionality and there are "internet security" versions. Firstly, it is hard and sometimes impossible to install and use standalone AV and FW. Sometimes I can't avoid them (i can't install KAV2010 without removing Outpost firewall etc). Secondly, complex solutions have some disbalance. Farewall from famous antivirus-brand is so user-friendly that is not suitable for me (lack of details in Norton Internet Security for example) and antiviruses from famous firewall-brands are still weak, it is proved by tests. What is today best-practices in case of functionality and security?) Some internet-security complex or two standalone applications from different vendors?

  • Which static electricity prevention tools do actually work?

    - by Boris_yo
    I need a device that would discharge static electricity from my body in order to safely work with electronics. I have looked and found some that interested me, but I don't know whether they work: Anti-Static Wrist Strap Anti-Static Release Discharger Keychain Anti-Dissipative Wrist Strap Anti-Static Rubber Finger Stalls Which of above mentioned actually do something? Do I also need and anti-static screw box? It has holes that screws get put in. Will I need magnetic screwdriver to pull screws out?

  • Powershell and long-running external tools?

    - by leeand00
    I'm trying to compact a MS-Access database using JetComp.exe using a powershell script. Here is the operative lines: # 4. Run JetComp LogWrite("Begin: Running JetComp") .\JETCOMP.EXE -src: $srcDB -dest: $dstDB | Out-Null #Run this command and wait for it to finish... IfErrorExit("Error Compacting Database") LogWrite("End: Running JetComp") The JETCOMP.EXE program seems to complete long before it is actually finished and the $dstDB ends up being smaller than the compact should even make it. Initially ($srcDB) it's about 1.8 GB and by the time the command finishes it's about 300,000 kb (about 0.29 gb) that's a pretty long way off from 1.8 gb which when compacted manually ends up being about 1.6 gb. Is there some sort of timeout I don't know about in powershell scripts? P.S. I know that when running JETCOMP.EXE manually, that the system often detects it as "not responding" even though it's actually getting the job done, and waiting long enough will allow it to complete.

  • Visual Studio 2008 Debugger really slow with SSD

    - by Doug
    Hey guys, my setup is a laptop with Win 7 64bit, VS2008 SP1 on an intel x25-m 4gb RAM with page file turned off (no need) and 2.2 core duo What happens is weird: When i build my project and attach the debugger the symbols load REALLY slowly... like 1 every 5 secs Sometimes the symbols will fail to load at all. This is driving me crazy as this was a freshly installed win 7 box with default VS installation, working on ASP.net web applications... i've never had to use symbol servers or any of that jazz so i'm quite frustrated. With this SSD it should breath fire as it does with loading and doing everything else. Am i missing something?

  • Tool to monitor file size, file existence, parse xml, etc

    - by Artur Carvalho
    I'm trying to find some tool that helps me monitor several things. What are some requirements: Shows results on a web page. Checks existence of files/folders Checks sizes of files/folders Can parse xml files Can have several status depending if it's for instance, after 9pm Ping workstations/Servers to ensure they are on or off create daily/weekly/monthly reports (pdf, html, csv) show daily/weekly/monthly scheduled tasks check if specific users are logged in a machine check which users are logged in in a machine I've looked into some solutions but could not find what I wanted. Usually tools like nagios are more focused in servers, and spiceworks is not so specific. At this point I'm using a little powershell script that does several of these items, but before losing more time probably reinventing the wheel, what tools are out there? Thank you in advance.

  • How do I figure out what is changing the userWorkstations attribute in Active Directory?

    - by Martin
    I just took over the IT for a medium sized business with a three domain controllers (2003/2008 Standard) and whenever I create a new user, after some time the user account cannot log into most machines on the network. I have traced this back to the "Log On To..." area becoming populated with a small list of machines. Even when I set the option to all computers, this list comes back after some time. I started hunting for vbs and ps1 scripts with the word "workstations" in them on all domain controllers to see if there is some kind of script to blame, but I have thus far come up empty handed. Is there a known software suite that can cause this (Microsoft Forefront, etc)? How can I figure out what is causing this list to change?

  • DB2 LUW tools for diagnosing issues when the stuff hits the fan

    - by Ichorus
    I am no DBA and very much a novice when it comes to DB2 so even 'obvious' answers are welcome to this question: I love db2top but sometimes I cannot get it to run if the load average is high on a db2 LUW. This morning I was looking at an issue where load average shot up suddenly, I could not get db2top to come up and I needed to find out what was happening. What can I do to find out who is doing what in this situation? I suspected a horribly bad query was being run by someone...is there a good way to find information on poor performing SQL on the fly in that type of situation? Are there any good ways to collect good, actionable stats who/where bad sql is coming from in the event that load average is so high? I know about db2pd but I am not sure how to use it effectively and slogging through tens of thousands of lines of raw data is probably not the most efficient way to get at the heart of a problem. Any tips or resources?

  • How should I debug a vb.net website in iis6 that is throwing 'Deadlock detected' errors and becomes

    - by jskunkle
    A few times a day, our vb.net (IIS 6.0) website is randomly throwing the following error and becomes completely unavailable for 5-15 minutes at a time while the application is recycled: ISAPI 'c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected'. The website ran for months on the exact same server in beta without problem - but the problem started over the weekend when we made the site live. The live site is under some load but less than many of our other production websites. How should I attack this problem? I've looked into orphaning the worker process and creating a dump file - but I'm not sure how to analyze that. Any advice or information is appreciated. Thanks, Shane

  • Tools to backup an external hard disk

    - by Kaushik Gopal
    Hey people, What's the best method to take an exact copy of my external hard disk? A guru suggested rsync, but I was wondering if there's an easier alternative. I do remember reading somewhere that Acronis also does this. Was looking for your advice on the best option. I'm running Windows. Essentially i have an external HDD which has a lot of stuff synchronized across various pcs. I wish to take a backup of this external Hard disk (ext.HDDs aren't entirely reliable so want to keep a backup of my ext.HDD). Cheers. K

  • Node app crashes after a while on micro EC2 instance even with supervisor

    - by Justin Meltzer
    I'm using supervisor to start my node.js application on a micro EC2 instance. However, the app only stays running for some time until it eventually shuts down. Not exactly sure how long the app stays running but I'm guessing for about a few hours or so. Sometimes less. My question is where on the remote server should I be looking in order to debug this kind of issue? I'm running an Amazon Linux AMI.
