• Does laser printer use toner when switched on/off?

  - by Alan Harris-Reid

  I have recently purchased a HP LaserJet M175nw laser printer which goes into sleep-mode after 10 minutes of non-use. I know sleep-mode uses a very small amount of power, but the flashing light on the control panel is driving me nuts! I know I can turn-off the printer via. the on/off button, but when it is turned-on manually, there is some whirring sound which I guess might be the machine warming-up. My question is... Is any toner used during this warm-up (or cleaning) cycle? Am I better-off keeping the printer in sleep mode, or is it ok to turn off manually? TIA Alan

• Excel VBA Function runtime error 1004: Application-defined or object-defined error

  - by music2myear

  I'm trying to learn functions for the purpose of simplifying and reusing code whenever necessary. I began by turning something I use pretty often into a function: Returning the integer value of the last non-blank row in a spreadsheet. Function FindLastDataLine(strColName As String) As Long FindLastDataLine = Range(strColName).Offset(Rows.Count - 1, 0).End(xlUp).Row End Function Sub PracticeMacro() intItemCount = FindLastDataLine("A:A") MsgBox ("There are " & intItemCount & " rows of data in column A.") End Sub When I run this I recieve the runtime error '1004' "Application-defined or object-defined error" which Help helpfully defines as "someone else's fault" to quote not quite verbatim. Where might I be going wrong?

• How can I uninstall a clustered SQL instance if the cluster has been destroyed?

  - by Bob

  First time going through this scenario, and apparently I did it very wrong. On the DB servers I deleted the cluster group that held SQL and Reporting Services. I then destroyed the cluster. Then I tried to uninstall SQL. No dice. SQL still thinks its part of the non-existant cluster and will not let me uninstall it. I went into the Maintenance menu of the SQL setup and tried to Remove Node...nope. Unless I find a way out of this I will have to rebuild the OS if I can't get SQL off the box.

• Spam just keeps on coming

  - by Campo

  I administer a Windows Server 2003 with Exchange 2003 as well as GFI installed. I am watching the GFI dashboard and every third email is spam. Not only that it goes to a non existent address then the [email protected] sends out an NDR to the sender. Should I be worried about this? I know it is directory harvesting but we have directory harvesting turned on in GFI and I do see it is working but obviously doesn't work for emails that don't exist. My issue is I would turn off NDR but then people who legitimately mistype and email address to our domain will never know their email did not get to the recipient. What do others do to combat spam? Is 3 times the amount of spam to ham normal? We filter out 90% of the spam but some does get into the users inbox. Thanks for the suggestions and advice!

• How can I configure Adobe Help so it doesn't chatter so much with Adobe's domain?

  - by Michael Prescott

  Adobe Help that came with Creative Suite 5 and/or Flash Builder Pro is constantly creating network traffic with an Adobe site, www.wip4.adobe.com In the Adobe Help application Preferences, I find that I can change the settings so that I must manually download updates, but apparently the application still likes to call home and chatter non-stop with www.wip4.adobe.com. I could use something like Little Snitch to block all this spyware-like behavior, but I'd really prefer to just change the application's behavior. Is there a hidden setting or configuration file to adjust this behavior to something more appropriate and polite?

• nginx proxy pass redirect through load balancer

  - by Brian

  I have several backend webservers that are load-balanced using LVS. These machines have only internal non-routable IPs on them. The load-balancer is the only machine with an external IP. This setup works great. I would like to add another webserver for image serving, but it will not be part of the load-balanced pool. Is it possible to proxy pass from the load-balanced web servers to the image server and have the response redirected to the client? Client--external LB--internal web server--internal image server I've gotten proxy pass working when I remove the LB from the equation, but no luck when trying to use it.

• Is it possible to upgrade using the Windows Server 2012 evaluation?

  - by Cerebrate

  I've got a Windows Server 2008 Standard installation here that I'm trying to upgrade to Windows Server 2012 Server, using the evaluation version. (The scenario is essentially that I need to test the upgrade, and specifically the upgrade process, before we spend the money on going ahead with the actual upgrade.) When I try to upgrade, it fails with the message: "Windows Server 2008 Standard cannot be upgraded to Windows Server 2012 Standard Evaluation (Server with a GUI). You can choose to install a new... (etc., etc.)" Is this (non-upgradability) a known limitation of the evaluation version? (Unfortunately, I haven't found a clear answer on this point.) And if not, any thoughts on where else I might look for the problem and solutions to it?

• Is there any way to get tree organisation for Windows 7 file explorer favorites?

  - by fostandy

  In XP there was a MenuBar called Favorites which seemed to be based on Internet Explorer Favorites. It was fantastic because it allowed for very fast tree style navigation (if set up correctly you could navigate it using first letter keystrokes, so to access a shortcut named "videos" in a folder named "files" was as quick as Alt-A f v) This was removed in Vista (and imo generally regressed the file explorer). This was fine because I never used it, but I'm resigned to eventually embracing the inevitability that is Windows 7. Dealing with a single non-nested list of favourites is pretty painful to me as I have quite a lot of them. Is there a way to make a tree like favorites structure in Windows 7? My fingers are crossed.

• Best labeler for the server room?

  - by Matt Simmons

  Right now, I've got a Brother P-touch labeler that prints four or five sizes of text on one long label. It has features such as italics and bold. It's...non-ideal. What do you use in your server room? I have heard of labelers that will print vertically as well as horizontally, or which can produce labels for cable management as well. I also think it would be great to be able to produce barcodes for my tapes (LTO-3). So basically, I would like a labeler that prints normal, can print cable labels, and can print barcodes. Unicorn optional. Any ideas, or could you even suggest the best labeler for each solution?

• ISCSI: Ethernet cable maximum length vs. SCSI command timeout

  - by Jeremy Hajek

  I have a question about a non-optimal setup and the practical implications of this. Ideally you would place the ESXi server right in the same room as the FreeNas white box end of question. My situation is this: I have a run of ~125ft of Cat 5e connecting a ESXi server to a FreeNas whitebox in the server room. I know the distance of the ethernet cable is within the maximum distance for ethernet traffic but I have two questions... Can Cat 5e support gigbit speeds at that distance if the switch on the back end is a linksys SRW-2048? Should I be concerned about the distance causing data read and write timeouts in the SCSI portion--(disk operations of the ESXi)?

• Obsessive behaviors in sysadmins

  - by squillman

  I have been told by colleagues (mainly non-technical) that some of my admin behaviors border on / cross the line between normal and obsessive, which sometimes leads me to wonder how screwed up I really am (read "how screwed up everyone else really is"). What are your obsessive behaviors when it comes to your sysadmin tasks and job functions? What do you do religiously that would make you twitch if you didn't do it or that others just roll their eyes at? I have reasons for my actions. I want to prove to my coworkers that I'm not alone.

• Fastest web server for serving static content

  - by Swader

  Hello, I'm optimizing our system for some faster static content delivery, and was wondering if anyone has any proper experience with the fastest web servers out there for such a purpose. From the three main candidates I've considered, Nginx, Cherokee and Lighttpd, each seems to have its own problems - but the reports I've read online are somewhat biased and lean towards whichever server the user is currently using. Any ideas on where to see a proper benchmark for this specific purpose, or at least a non-biased list of pros and cons? Any personal experiences and pitfalls I should be vary of? Thanks Edit: Serverfault.com gave the answer as nginx. I'd still like to hear some developer thoughts from this end of the universe.

• Security: Unable to display current owner

  - by Jim McKeeth

  I have a user with local administrative rights on their Windows 7 64-bit box. They extracted a file from a zip file they downloaded with the Zip shell extension to their desktop on a non-encrypted or compressed NTFS volume. Unfortunately they cannot open it. I tried to take ownership of it and it just reports "Access is Denied" and for the current owner it reports "Unable to display current owner." At this point the file cannot be deleted, executed or modified. I have actually seen this exact same happen in Vista before, but I can't for the life of me remember how to fix it. Any ideas how it happened or how to fix it? I'd be happy just to delete it without a format at this point.

• How to put 1000 lightweight server applications in the cloud

  - by Dan Bird

  The company I work for sells a commercial desktop/server app that runs on any non dedicated Windows PC or server and uses Tomcat for all interactions with the application. Customers are asking that we host their instance of the application so they don't have to run it locally on their own servers. The app is lightweight and an average server, in theory, could handle 25-50 instances before users would notice a slowdown. However only 1 instance can run per Windows instance (because the application writes to a common registry branch) so we'd need something like VMWare to create 25-50 Windows instances. We know we eventually need to reprogram to make it truly cloud-worthy but what would you recommend for a server farm or whatever for this? We don't have the setup to purchase our own servers so we must use a 3rd party. We have budgeted $500 - $1000 per year per customer for this service. Thanks in advance for your suggestions, experiences and guidance.

• How to set default permissions for automounted FAT drives in Ubuntu

  - by piman

  I've got many FAT32 drives that I'd like to mount in Ubuntu such that they have permission mode 700 for directories and 600 for all other files. By default, they have 755 for all files, which is not particularly useful since almost no non-directories should be executable, and it screws up version control repos hosted on the drives. "Back in the day" I would have had the drives listed in /etc/fstab with the umask/dmask I want and there was no such thing as a default. These days, drives automount under their volume names. Which is great, except now I have no idea how to set the default. I have tried changing the /system/storage/default_options/vfat/mount_options gconf key with no apparently effect. It was 077 initially but the mounted drive reflected a default of 022; changing it and re-inserting the drives resulted in the files still having permission bits of 755.

• Scalable WordPress Host for High-Volume Site?

  - by Jonathan Eunice

  I need recommendations for a scalable web host for a high volume WordPress web site. For my purposes, high-volume might be 100K-500K visitors/hour. Might think towards a 1M/hour burst rate as a "high water mark." I know WP isn't the highest-performing platform out there (ha!), but it's non-negotiable. I can do "the usual optimizations" (e.g. put static files in a CDN, run and follow the advice of performance analyzers like YSlow, etc). But it will still be WordPress, and there will be a dozen or so plugins involved. So, where to host the site? Most "what's the best WordPress host?" discussions seem to focus on lowest-cost. I need the opposite. What are the high-volume, scalable, or clustered WordPress hosts with which you've had great experiences?

  Is there a way to run Wave Trusted Drive Manager from a live-cd to access a non-bootable SSD with Full Disk Encyption hard disk? http://www.wave.com/products/tdm.asp The crashed disk is a Samsung SSD PB22-JS3, 128Gb. Is has bad blocks at 128-block intervals. If the SSD password could be unset, is sending the unit for disaster recovery possible? What might cause a nearly new SSD to crash in this way, and what is the probability of it happening again? We have other units in service an I can do without every laptop disk in the company crashing...

• Improve performance on Lync desktop sharing

  - by Trikks

  I'm using Lync 2010 server to handle some clients communication and screen sharing. The biggest issue is the performance with screen sharing, it is of rather high quality but the frame rate is very poor. I have been reading and searching a lot on the subject and 95% of all topics is about bandwidth, we have a 200/200 MBit Internet connection solely for this application. Also my test machines runs on an internal gigabit lan. The speeds between all boxes is hysterically fast. Next step was to ensure that there where some profiles for different bandwidths, so i registered some New-CsNetworkBandwidthPolicyProfile -Identity 50Mb_Link -Description "BW profile for 50Mb links" -AudioBWLimit 20000 -AudioBWSessionLimit 200 -VideoBWLimit 14000 -VideoBWSessionLimit 700 New-CsNetworkBandwidthPolicyProfile -Identity 100Mb_Link -Description "BW profile for 100Mb links" -AudioBWLimit 30000 -AudioBWSessionLimit 300 -VideoBWLimit 25000 -VideoBWSessionLimit 1500 Nothing fancy happend here either. Non of the test boxes have anything from Norton installed, they doesn't have any firewalls running (nor does the Lync server), all fences are down in this environment just for the testing. Is there any thing that I may have missed to improve the quality of this? Thanks

• How to dynamically set HTTP Header in Apache 2.2?

  - by Michael

  Seems like this should be easy, but I cannot figure out the syntax. In Apache, I want to use the value of an existing request header to set a new request header. Some simple non-working code that illustrates what I'd like to do: RequestHeader set X-Custom-Host-Header "%{HTTP_HOST}e" Ideally, this would make a new HTTP header in the request called "X-Custom-Host-Header" that contains the value of the existing Host header. But it does not. Perhaps I need to copy the existing header into an environment variable first? (If so, I can't figure out how to do that either.) I feel like I'm missing something obvious, but I've gone over the Apache docs and I can't figure it out. Thanks for any help.

• Nginx redirect one path to another

  - by SteveEdson

  I'm sure this has been asked before, but I can't find a solution that works. A website has switched CMS services, but has the same domain, how do I set up an nginx rewrite for a single page? E.g. Old Page http://sitedomain.co.uk/content/unique-page-name New page http://sitedomain.co.uk/new-name/unique-page-name Please note, I don't want everything within the content page to be redirected, but literally just the url mentioned above. I have about 9 redirects to set up, non of which fit in a pattern. Thanks! Edit: I found this solution, which seems to be working, except for the fact that it redirects without a slash: if ( $request_filename ~ content/unique-page-name/ ) { rewrite ^ http://sitedomain.co.uk/new-name/unique-page-name/? permanent; } But this redirects to: http://sitedomain.co.uknew-name/unique-page-name/

• vmware workstation - virtual network adapters missing from ipconfig, still show in networking (XP host)

  - by Adam

  Hi Folks - here's a new one for me, and my first time posting here: I installed VMWare workstation 7.1 on a new PC. VMWare properly installs the virtual network adapters under the Network Connections control panel, however for some reason they do not show up under ipconfig, which is very weird. They also don't appear anywhere in "route print". I don't have network connectivity to the VM. My guesses are perhaps some conflict with Symantec AntiVirus or Symantec Client Firewall. Tried the following things: enabling TCP/IP in the virtual network adapters (they often get installed with it disabled for some reason) Restoring defualts in the VMnetcfg gui tool (this causes an uninstall and reinstall of the virtual network adapters on the host) Re-installing vmware workstation Uninstalling checkpoint secureremote and then reinstalling vmware Just to be clear, this problem is totally on the host. In my searching for stuff about (non-vmware) adapters missing from ipconfig, I see some posts about resetting the TCP/IP stack using netsh. Looking into that next... Thanks!

• "Fuzzy" Display Problems on New OpenSUSE 11.3 Install

  - by Kryten

  Hi, I have a old Desktop that has a new installation of OpenSUSE 11.3 on it. To get straight to the point, whenever I try to start-up OpenSUSE, my display goes "fuzzy" (almost like a badly tuned TV) and sometimes (not always) my monitor goes black and says "Out of Range: 15.6kHz/49Hz": I assumed that this was a driver problem, so I download the drivers from nvidia and ran the shell script, completed and rebooted. Then OpenSUSE failed to boot with something like "nscd failed to start". At that point I decided to re-install and I did, but this time I tried un-checking "Automatic Configuration" to see if that helped. Got through the install and still have a problem. Unfortunately, my Linux troubleshooting skills are non-existent, so has anyone got any ideas on what could be the problem (is it the display driver?) and how I can fix the problem?

• Scheduling VMWare ESXi 4.1 VM Restart

  - by Robin Day

  We had a virtual machine running on a VMWare Server host on Windows Server 2003. The machine is set up with non persistent disks. We had a windows task schedule set up that ran a batch file to reset the machine each week so that it returned to it's original state. The batch file that we had running was: "C:\Program Files\VMware\VMware Server\vmware-cmd" "C:\Virtual Machines\VirtualMachineName\VirtualMachineName.vmx" stop hard "C:\Program Files\VMware\VMware Server\vmware-cmd" "C:\Virtual Machines\VirtualMachineName\VirtualMachineName1.vmx" start We have since migrated this machine to the free version of ESXi 4.1. Can anyone let me know if and how it is possible to schedule such a restart?
