• How to disable Windows 8 lock screen?

  - by Filip

  So I took a plunge and installed Windows 8 Consumer Preview on my main home PC. So far so good, but there is one annoyance - the system "locks" the computer after a period of inactivity causing me to re-enter my password. I really would like to avoid this, but have no idea how. I already tried the power settings (no pass on wake up) and the screen saver settings with no luck. Is this some sort of bug, or am I missing something? P.S. In this case I favor convenience over security.

• Teamviewer and Virtualbox issue: some keys don't work

  - by Barranka

  I use Teamviewer on a laptop to connect to a desktop computer running Debian Linux. On this desktop computer I run Windows inside a VirtualBox VM. I have no problems interacting directly with Linux, but when I try to interact with Windows inside Virtualbox, some keys simply don't work! (e.g. period, "@", quotes). Is there something I can do to make the full keyboard of my laptop work correctly with the Virtualbox VM inside the remote host? Specs: The remote host machine is an Intel i7 running Debian squeezy (64 bit) I'm using Teamviewer 7, on both the host machine and the laptop Thanks

• Wake on Lan/Wan won't work after some time has passsed

  - by Vian Esterhuizen

  I have the following set up: Gigabyte Z77X-UD5H Wake On Lan Enabled Asus N66U Port Forwarding Static IP assigned to my computer Windows 7 Advanced Power Management - PCI Express - Off Intel 82579V - All options under Power Management checked I'm trying to set this up for Wake on Wan capabilities. If I shut down my computer and immediately try to Wake on Wan (and Lan) it works and starts up. While the computer is on, I've used a few WOL specific packet sniffers and the packet comes through on the correct port. After any period of time over a few minutes, waking on Wan or Lan won't work. The back "activity" light is blinking on my ethernet port on my computer, as well as on the router, so I would assume the network card is on and able to receive a signal. Any ideas? Suggestions? What can I do to troubleshoot the problem?

• Vlan and Switch setting - dummy

  - by Andras Sebestyen

  I need to speak tomorrow the network engineer and I would like to understand his so apologise for the Dummy question: In the school we have a cab with a 24 port Netgear manageable switch with an admin and curriculum VLAN settings. Usually, as I over heard, in the morning and around 4.30pm there are a slowdown period on the computers which connect to this switch. No one could track this back yet. Questions: What is the best way to track back this slowdown Would it be a temporary solution to physical separate the two network with 2 switches If that would work how can I link them together to be able to see the curriculum from the admin side. Do I need an extra router then? Too many questions but I have no clue where to start and the gentleman will be paid by hours... can you see where I am coming from?:) Could you guide me in the right direction please? Any comment would be appreciated and please send links if you down vote the question:)

• Recommendations for VMWare web server environment with load balancer.

  - by Ben

  We run IIS websites on a VMWare production server that pull image content and video content from a separate IIS instance on another server (media server). The media calls (images and video) are straight http:// calls and not using a streaming application. During peak traffic periods, we clone the production server five times and have a load balancer distribute traffic to all five production servers. The media server does not get ramped up. We noticed that the processing and resources on the media server gets very taxed during this period. Would it make sense to run the IIS instance for the media server locally on the production server and have it cloned with the production servers, then have a rule on the load balancer negotiating these media calls from the website? Would it be better to allocate more resources (memory and CPUs) to the media server VM and not clone it with the production servers? Recommendations are sincerely appreciated.

• Best way to bring a system down with a "maintenance" message?

  - by iftrue

  What's the best way to bring down an apache2/tomcat6 setup for maintenance? Specifically, apache2 can stay running, but tomcat needs to restart to accomplish a number of tasks. My initial thought is to change the root directory in the httpd.conf VirtualHost entry to point to a new location, then issue a force-reload command to direct traffic away from the actual tomcat application. After some period of time, I perform tomcat maintenance, switch the VirtualHost entry, and force-reload to begin directing traffic back. Is there a better way to do this? I'm looking to start work on a rather extensive web application, and my deployment procedure right now involves shutting everything down and bringing everything back up. Is there a better way to do this than what I've proposed?

• Why does my DNS change (and break) at regular intervals?

  - by Peter Kelly

  I have a laptop running Windows 7. Up until recently, everything was fine. We have multiple devices in my house connecting to the one access point with no problems. No issues with ISP. Now my Windows 7 PC DNS settings change every minute or so. Before the problem occurs if I do an ipconfig /all I have two DNS settings (primary/secondary) and everything is fine. After a short period of time this change to a sole DNS, 10.0.0.1. Webpages no longer resolve. If I do an ipconfig /renew, this fixes the problem. I have tried uninstalling various programs I thought might be related but the problem persists. Any ideas of potential causes?

• Router's ssid changes from infrastructure to ad-hoc

  - by waldo

  For a period of time the router's ssid is shown (on various computers) as a normal infrastructure network - computers connect fine and everything works however after a few minutes / hours all computers see the same ssid as an ad-hoc network (not infrastructure). At this point a computer that was already connected continues to work - a computer that isn't cannot connect. Rebooting the router temporarily restores the visibility of the correct infrastructure ssid. Is something interfering? Connecting computers: macbook (2009), iphone 3g, windows vista desktop, windows xp desktop. Details: - D-Link DSL-2740B router set to WPA2-PSK (Personal) - Enable Wireless : Yes - Wireless Network Name (SSID) : ###### - Country : Australia - Wireless Channel : 1 - 802.11 Mode : Mixed 802.11n, 802.11g and 802.11b - Channel Width : Auto 20/40 MHz - Transmission Rate : Best (automatic) - Hide Wireless Network : No - Group Key Update Interval : 0 (seconds)

• OEM to Virtual Machine for Diaster Recovery / Business Continuity.

  - by James

  Hello, We are trying to deploy a Business Continuity Appliance (Zenith BDR) for a customer and one of the features is the ability to bring up the failed server in a virtual machine on the appliance. Great feature. However, the customer has OEM version of Server 2003 on that server and it comes up requiring immediate re-activation since it is now on different hardware. We would be happy with a 2-3 day grace period which is what we expected, but this isn't happening. What are the solutions without having to purchase another VLK copy of Server 2008 and re-installing the server with that license just so we can set this thing up.

• Packet loss with all adapters on one PC only on the LAN

  - by Enigmativity

  I have a Windows 7 64-bit machine that is losing up to 20% of IP packets on both adapters - wireless & LAN. Browser traffic appears to be affected the most, but it is happening to all protocols. All other computers on the network are functioning fine. If I ping from my faulty machine to any machine on the LAN (wired or wirelessly), including the router/gateway and internet sites, I get up to 20% packet loss. If I do the following commands: ipconfig /release ipconfig /renew then I sometimes get my network performance back for a matter of a few seconds to less than a couple of minutes. Rebooting also works for a short period of time. This problem has been occurring for a couple of months and is getting worse. The computer used to work just fine. I updated the wireless adapter firmware the other day with no effect. Does anyone know what is happening?

• Can I make Apache drop a connection when matching a URL?

  - by PP

  Using mod_rewrite I can construct a rule to respond with a clean error code (e.g. 404 not found, 410 gone, or 403 unauthorised) when a page is requested that I don't want to serve. But frequently I get completely erroneous requests from hackers scanning my website for vulnerabilities or possibly cross-site scripting attempts. For these customers I do not want to return a clean error - I'd rather do something else like immediately drop the connection with no response or, alternatively, hold the connection open for a lengthy period of time to frustrate the automated process. Any ideas how to accomplish this with Apache? I've read that nginx has the ability to immediately terminate a connection when a particular pattern is matched.

• IIS/SMTP - unable to move emails from inetpub/mailroot/Queue due to file lock

  - by Bryan Roth

  I have a listener that processes emails in the inetpub/mailroot/Queue directory. Once the listener is done processing an email it proceeds to move the email to another directory. However, moving the email is not possible due to a file lock by the process inetinfo.exe. I have noticed that this file lock is released after a period time that ranges from several hours to several days. You can see that the Queue directory can get pretty full over time. The only way I have been able to work around this is by manually stopping and starting my SMTP virtual server in IIS. Is it possible to release this file lock programmatically? If not, is it possible to expedite releasing this file lock?

• Strange performance from RAID5 using WD RE4 disks

  - by Howard

  I've noticed a bit of a performance issue with some WD RE4 drives I'm using under AMD's hardware RAID solution. First a bit of background: Environment: Windows 7 home premium x64 HDD's: 3x 1TB WD Raid Edition 4 in a RAID 5 setup with 128 kbyte stripe (2TB usable space) Testing Tool: HD Tune, process set to "High Priority" Processor: AMD Phenom II x6 1100T Ram: 16GB DDR3/1600mhz Motherboard: MSI 970A-G45 The image below pretty much depicts the issue I'm having. Every test has the same thing, a period of similar length where the performance drops to a few megabytes a second. This can't be a TLER issue as the purpose of RE4's is to work around that. Any help would be greatly appreciated.

• How does operating system software maintains time clocks?

  - by Neeraj

  Hi everyone, This may sound a bit less relevant but I couldn't think of a better place to ask this question. Now consider this situation, you install an OS on your system, set the timezone and time, do some stuff and turn it off. (Note that there is no power going in to the computer). Now next time (say after some hours or days) you turn it on again, and you see the updated time. How is this possible even when my computer is not connected to the internet and was consuming no power during the period it was down.(Is there some kind of hardware hack?) please clarify!

  Hi all. I've recently installed mod_fastcgi and Apache 2.2. I've a simple cgi script as below (test.fcgi): #!/bin/sh echo sadjad But when I invoke "mysite.com/test.fcgi" I see "Internal Server Error" message after a short period of time.

• Is It Possible to Change Default Windows Idle Time for Task Scheduler?

  - by alharaka

  From the official Microsoft docs: Detecting the Idle State The Task Scheduler service will verify that the computer is in an idle state every 15 minutes. The computer is considered idle if all the processors and all the disks were idle for more than 90% of the past 15 minutes and if there is no keyboard or mouse input during this period of time. Besides, any presentation type application that sets the ES_DISPLAY_REQUIRED flag will make Task Scheduler to not consider the system as being idle. In Windows 7, Task Scheduler considers a processor as idle even when low priority threads (thread priority < normal) execute. Is there any way to change the time to less than 15 minutes minutes? Am I assuming this hard-coded and impossible? My Google-fu has eluded me so far and I found nothing, but wanted to check here before giving up.

• AWS Elastic load balancer doesn't decrease instances from Alarm Trigger

  - by jchysk

  I have a load balancer that I created an auto-scaling-group and launch-config for. I created the auto-scaling-group with a min-size of 1 and max size of 20. I have a scaledown policy: as-put-scaling-policy SBMScaleDownPolicy --auto-scaling-group SBMAutoScaleGroup --adjustment=-1 --type ChangeInCapacity --cooldown 300 Then I set up an alarm: mon-put-metric-alarm SBMLowCPUAlarm --comparison-operator LessThanThreshold --evaluation-periods 1 --metric-name CPUUtilization --namespace "AWS/EC2" --period 600 --statistic Average --threshold 35 --alarm-actions arn:aws:autoscaling:us-east-1:policystuffhere:autoScalingGroupName/SBMAutoScaleGroup:policyName/SBMScaleDownPolicy --dimensions "AutoScalingGroupName=SBMAutoScaleGroup" When average CPU usage over 10 minutes is under 35, in CloudFront the alarm shows up as "In Alarm State" but doesn't decrease the number of instances. Also, if there's only one instance running it'll spin up another to 2 even if a scale up alarm isn't hit. It seems like the default value is just set to 2 somehow. How can I change this?

• How can I set a time-limit on a batch file?

  - by drknexus

  I have a batch file that calls an external program that periodically hangs. What I would like to do is set a time limit on the batch file / CMD prompt such that it automatically closes after a certain period of time. One catch is that the external program that hangs may have one or more instances running at a given time, and I only want the batch file hitting its time limit to close the instance of the program triggered by the batch. How can I accomplish this? Ideally a solution would work on Windows XP, Vista, and 7.

• What is the method to reset the Planar 1910m monitor?

  - by Richard J Foster

  My monitor (a Planar, apparently model number PL1910M) is not working. (It is flashing a green / orange sequence which I believe to be an error code. The sequence, in case it helps consists of orange and green three times quickly followed by a longer orange, then another green followed by a long period where both colors appear to be present). I vaguely recall a co-worker suffering from a similar problem, and our IT department "resetting" the monitor by holding down a certain set of keys as they apply power. Unfortunately, I do not remember what that key sequence was, our IT department is not responding, and the Planar web site is blocked by the content filtering firewall we have in place! What is the sequence to perform the reset? (For bonus geek-credit, what does the code mean... as if it indicates a blown component clearly a reset will not help me. ;-))

• Speeding up ROW_NUMBER in SQL Server

  - by BlueRaja

  We have a number of machines which record data into a database at sporadic intervals. For each record, I'd like to obtain the time period between this recording and the previous recording. I can do this using ROW_NUMBER as follows: WITH TempTable AS ( SELECT *, ROW_NUMBER() OVER (PARTITION BY Machine_ID ORDER BY Date_Time) AS Ordering FROM dbo.DataTable ) SELECT [Current].*, Previous.Date_Time AS PreviousDateTime FROM TempTable AS [Current] INNER JOIN TempTable AS Previous ON [Current].Machine_ID = Previous.Machine_ID AND Previous.Ordering = [Current].Ordering + 1 The problem is, it goes really slow (several minutes on a table with about 10k entries) - I tried creating separate indicies on Machine_ID and Date_Time, and a single joined-index, but nothing helps. Is there anyway to rewrite this query to go faster?

• Keeping rackspace vserver alive

  - by mit

  It appears to me that rackspace somehow freezes cloud VMs after some idle time. This means the first page request to a php page takes much longer to respond than the subsequent requests. I am actually querying a machine with wget from a different host now to keep it "alive". But I wonder what frequency would be necessary. Does anyone know the time period after which they send a VM to "sleep"? I guess it would be some minutes. EDIT: There is no caching involved on the php site. It just recently moved from another vhost and there was never such latency on the first request.

• Set maximum requests per IP in IIS7

  - by Maxim V. Pavlov

  I have a web site deployed to IIS 7. One page it is has 15+ .js files linked to it. Last two files referenced in <head> tag (loaded last) get 403 forbidden response from server. I have enabled FailedRequestTracing and have been able to see a detailed error code which is 403.502. I suppose over a very short period of time I am just pulling to much and the IIS blocks me. Is there a way I can configure the limit to enable larger number of requests and get rid of 403.502 error?

• Remote location looses connectivity

  - by user24559

  I have a remote location that has constant internet access using DSL. The remote location only has three Linksys cameras that use the internet access with a router. There is no computer on the network. The router is configured to use the DYN.org service to keep the IP address updated if the internet provider assigns a new ip address. The problem I am having is the router after a period of time stops responding to incoming ping requests and the cameras are shown offline. However, if I keep one of the cameras constantly streaming data then the connection to all the cameras works just fine all the time. How can I keep the router from appearing to be sleeping and not responding to incoming requests? The router is the Linksys WRT300N.
