• cmd.exe version comparison?

  - by Paul

  When using batch files or console applications on Windows servers the window in question can allow text to be hightlighted (marked) for copying and pasting. Doing this pauses the batch/application and it will only resume after the copy operation. Or this is what I thought to be true. Recently on a Windows 2003 R2 SP2 server I noted that whilst the scrolling was paused the operations were not. Does anyone know if my description in the 1st para is true for older windows is not true for Windows 2003 R2 SP2 when it changed a full version comparison table for cmd.exe across different OS' ? Thanks for reading (Windows 2000 tag as that was the OS I used most before 2003 R2)

• UEC - Can the Cluster Controller and Storage Controller be seperate systems?

  - by Jeremy Hajek

  My department is implementing an Ubuntu Enterprise Cloud. I have done the testing and am quite comfortable with the 4 pieces, CC/SC, CLC, WS, NC. Looking at various documents below it appears the the Storage Controller and Cluster Controller (eucalyptus-sc and eucalyptus-cc) are always installed on the same system. My question is this: can I install the storage controller and the cluster controller on separate systems? http://open.eucalyptus.com/wiki/EucalyptusAdvanced_v2.0 the picture indicates that cc and sc are two different machines http://www.canonical.com/sites/default/files/active/Whitepaper-UbuntuEnterpriseCloudArchitecture-v1.pdf P.10 1st paragraph uses the word "machine(s)" http://software.intel.com/file/31966 P. 8 indicates the same separate architecture BUT... https://help.ubuntu.com/community/UEC/PackageInstallSeparate indicates below that the SC and CC are to be on the same system.

• Coldfusion deployment under Apache Tomcat with Virtual Hosts

  - by smalltiger85

  Hello, I'm looking for the proper way to share the Coldfusion engine for all my Virtual Hosts. This is how I have the virtual hosts configured on server.xml in the Tomcat conf: <Host name="localhost" appBase="webapps" unpackWARs="false" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> <Context path="" docBase="cfusion/" reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true"/> </Host> <Host name="mysite1" appBase="webapps" xmlValidation="false" xmlNamespaceAware="false"> <Context path="" docBase="/mnt/webroot/mysite1" /> </Host> This is not valid for me because I'm instantiating one Coldfusion process for every virtual host, and it requires me to copy the WEB-INF folder in every site. My question is, is there any way to share the same Coldfusion instance for every virtual host, mantaining the sites webroot outside of the cfusion folder? I'm using Apache Tomcat 6 and Coldfusion Enterprise edition 8. Many thanks.

• Schedule Task run Without Being Logged in

  - by Webs

  I have seen similar threads here and on the net, but I think my question is slightly different than what I can find... I have a script that runs perfectly when logged in with a service account I created specifically to run this script. But when I schedule it to run it hangs when trying to launch IE (the first part of my script). Without being logged in with that account I can watch the processes with task manager and see the processes running, but the script never finishes. I want to be able to run this script without needing to be logged in at all or even have the account be locked all the times. Is this possible? Or do I have to have the user account logged in? Any help would be greatly appreciated!

• Idle VMware Guests Resource Consumption

  - by Ravenor

  I want to setup a number of guests with multiple CPUs (4) and at least 4Gb ram running Ubuntu Linux. These machines will mostly be idle, but from time to time their workload will require all their resources, especially the CPU. The hosts are ESXi 5.x. The question is, am I right in thinking that the resource consumption of the machines when idle will be negligible? We know this true of disk and the CPU. The only concern left therefore is memory. Since ESX over-commits memory it makes sense that unused memory of any guest is paged out. If my thinking correct?

  - by Goober

  The Scenario I've got an iMac G5 20" (First All-In-One White Screen) PPC. It has an Airport Extreme Network card in order to wirelessly to connect to the internet. For the most part I connect using ethernet as opposed to wirelessly, but recently have had the need to connect using the wireless. The Hardware BT Home Broadband Wireless Router. iMac G5 20" From about 5 years ago (First All-In-One White Screen) The Issue Even though I know for a fact that It has connected to the internet wireslessly in the past, for some reason it can discover the wireless router, but upon entering the password it fails to connect. I have tried multiple times to no avail. I have 2 other Mac's on the network and a pc that can all connect wirelessly. However both the mac's. Question Any ideas as to why my really old iMac G5 can't connect wirelessly anymore!?

• How to watch 3D on Acer "3D Ready" projector?

  - by glenneroo

  We have here a Acer P1200 DLP projector which is "3D Ready" (using the BrilliantColor™ DarkChip™ 3) and documentation was not included in the packaging. We don't have a Blu-ray player and have no intention of purchasing one in the near future so I'm looking for a way to view encoded or streamed content. My question is: How is it possible to watch 3D content? What extra hardware/software will I need? EDIT: Found this information in the user manual: DLP 3D function: Choose while using DLP 3D glasses, quad buffer (NVIDIA/ATI…) graphic card and HQFS format file or DVD with corresponding SW player. 3D Sync L/R: If you see a discrete or overlapping image while wearing DLP 3D glasses, you may need to execute "Invert" to get best match of left/ right image sequence to get the correct image (for DLP 3D). ...but I'm still at a loss. What is a quad buffer graphics card?

• Looking for the best ec2 setup for 3 sites totaling in 1.5 mil in traffic monthly

  - by john h.

  I am looking to consolidate our current aws setup of 2 Large ubuntu ec2 servers and 2 large RDS server for our 3 websites that have a total of about 1.5 million hits a month and increasing every month with the majority of traffic (1 mil) to one forum site in the group and the rest of traffic to an ecommerce site and a small wordpress site. So here is my question/thought? Would it be better for us to combine the two ec2 large servers to just one and same with the 2 RDS servers so we run all three sites off one large ec2 and one RDS. -or- Should we setup maybe 2-3 smaller ec2 servers load balenced and a single RDS. -or- Something completely different setup? One concern is that if one site crashes it takes with it the others. It happened in the past but I am pretty sure its because of the forum software and not the server setup. -john

• Disable Memory Modules In BIOS for Testing Purposes (Optimize Nehalem/Gulftown Memory Performance)

  - by Bob

  I recently acquired an HP Z800 with two Intel Xeon X5650 (Gulftown) 6 core processors. The person that configured the system chose 16GB (8 x 2GB DDR3-1333). I'm assuming this person was unaware these processors have 3 memory channels and to optimize memory performance one should choose memory in multiples of three. Based on this information, I have a question: By entering the BIOS, can I disable the bank on each processor that has the single memory module? If so, will this have any adverse effects or behave differently than physically removing the modules? I ask due to the fact that I prefer to store the extra memory in the system if it truly behaves as if the memory is not even there. Also, I see this as an opportunity to test 12GB vs. 16GB to see if there is a noticeable difference. Note: According to http://www.delltechcenter.com/page/04-08-2009+-+Nehalem+and+Memory+Configurations?t=anon, the current configuration reduces the overall data transfer speed to 1066 and in addition, the memory bandwidth goes down by about 23%.

• Restarting Hudson - Windows Installation

  - by Toggo

  Whenever I update/install a new plugin or update hudson. Once the new plugin/update has been installed a button appears "Restart when no jobs are running." If I click this button hudson appears to try to restart but then just hangs. Has anyone else experienced this? Can hudson be forced to restart another way? I've tried restarting the service but this has no effect. I've asked this question over at stack overflow, so will update this if I get an answer from there. Thanks Tom

• Back up Windows 2008 SBS to iSCSI disk

  - by Farseeker

  I've almost no experience with SBS 2008, so please excuse my noob question! SBS 2008 only has the most basic backup utility built in as far as I can tell (similar to Vista), and it will only back up to physical volumes. I've read that you can set up a batch task to backup to a network volume, but right now I just need to get something deployed ASAP. We have an iSCSI target with plenty of free space. Is it worth backing up to an iSCSI target? Or am I wasting my time? If I need to do a recovery from the iSCSI disk, how would I go about it?

• Can I be a wireless server WITHOUT offering internet?

  - by Kenny Hendrick

  I would like to pull into a truck stop and offer a folder of free documentaries to quell some of the ignorance LOL I run Linux ";-) Very happy to have made that switch by the way...and have an internal wireless in the laptop but my bus has an antenna on the roof which I connect via usb to create a wireless signal (this is the one I'd like to focus on since it will offer the most reach to all those truckers out there. My question is this. I'm running apache2 and have a bunch of videos tossed into the www folder and can access it locally and would like others that frown on paying to use the truckstops slow internet service and would like an alternative by simply logging onto me and getting the narrow content I offer freely without passwords and the like. Has anyone a good means of doing this? p.s. I've done this in the past but am getting old and forgetful (my crutch)

• Time Machine (OSX) doesn't back up files in Mount Point or Disk Image File

  - by Chris

  Hi all, I found this Q&A (http://superuser.com/questions/148849/backup-mounted-drive-of-an-image-in-time-machine) and this prompted me to ask the following question: I have two disk images which are scripted to be mounted on login. These two disk images are always mounted to the same location. These two disk images are encrypted TrueCrypt volumes. Time Machine (TM) will only back up the disk images the first time they are mounted, but not after that. As I modify documents within the volumes throughout the day, the modified timestamps are adjusted properly. However, TM does not back them up. TM never backs up the mount points which are two folders within my home directory. Any ideas as to why neither the mount point or the image files are backed up? Do the image files have to be closed (unmounted) after being modified for TM to back them up? Thanks, Chris

• RAMDiskVE keeps causing computer to freeze

  - by Steph

  I found this in the Event Viewer logs: The description for Event ID 11 from source RAMDiskVE cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. Which doesn't say much. The details don't reveal much more: Failed to read configuration information from registry. 0000000002002C00000000000B0007C0000000000000000000000000000000000000000000000000 So my question is, what is RAMDiskVE and what device is it for? Basically I'm trying to rule out hardware but I have no idea what's failing...

• Is it possible to remove/hide Windows title bars?

  - by Igoru

  I'm very used to my Linux desktop, but in my new job I'm forced to use Windows. For efficiency, I'm veeery used to minimize/maximize using keyboard shortcuts and move/resize windows using alt+mouse. Thus, window titlebars and borders are useless, and I can remove them using Compiz. My question is: is this remotely possible to be done in Windows Vista? I could manage to quite reduce the borders, but the titlebars still bother me. I also found that Win+M minimizes a window, and I think that would help with the shortcuts also. As a help to understand how I'm used to live, here's a completely normal [reduced] window of my home computer:

• Bitlocker-to-go on fixed drive

  - by Unsigned

  Scenario Two drives are connected to a computer. One via a SATA-to-USB interface, the other directly via a SATA-to-eSATA cable. The drive on USB appears as a removable drive, the drive on eSATA appears as a fixed drive. Both use NTFS. The USB drive offers Bitlocker-To-Go, the eSATA drive only offers BitLocker. Question It is my understanding that drives encrypted with BitLocker-To-Go include an app to allow Windows XP read-only access to the volume. Is this the only difference, and is there a way to use Bitlocker-To-Go on the eSATA drive? Update Another difference is found here: The recovery key is required when a BitLocker-protected fixed data drive configured for automatic unlocking is moved to another computer.[1] Assuming that does not apply to removable drives.

• Dell OpenManage iDrac

  - by mhouston100

  I have installed OpenManage Server Administrator on a Windows 7 workstation with the assumption that nothing needed to be done on the actual server I am trying to manage. The server has an iDrac v7 component and I was under the impression that OpenManage just connects to that? When I try to connect I put the IP address of the iDrac console and the username/password and I get a 'Connection Error' message. So my question, does OpenManage have to be installed on the server that is to be managed, even if it has a DRAC connection?

• Strange Windows DIR command behavior

  - by user1167442

  I discovered this quite by accident while looking for a file with a number in the name. When I type: dir *number* (where number represents any number from 0 to 9 and with no spaces between the asterisks and the number) at the cmd.exe command prompt, it returns various files do not appear in any to fit the search criteria. What's weird, is that depending on the directory, some numbers will work and not others. An example is, in a directory associated with a website, I type the following: dir *4* and what is returned is: Directory of C:\Ampps\www\includes\pages 04/30/2012 03:55 PM 153 inventory_list_retrieve.php 06/18/2012 11:17 AM 6,756 ix.html 06/19/2012 01:47 PM 257,501 jquery.1.7.1.js 3 File(s) 264,410 bytes 0 Dir(s) 362,280,906,752 bytes free That just doesn't make any sense to me. Any clue? The question is posed on stackOverflow because the DIR command is often combined with FOR in batch programs. The strange DIR behavior would seem to make batch programs potentially unreliable if they use the DIR command.

• external HDD with SATA & USB interface? [closed]

  - by GregH

  Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.

• How can I install CentOS without a keyboard, mouse, or monitor?

  - by user1032531

  I will be buying a new computer which will be used as a CentOS server. I will put it on my home LAN, and once it is set up, will access it only through SSH. I don't want to spend a lot of money (maybe $500), and I don't want to buy another monitor or keyboard just to through them away after the server is setup. My question is how do I access the computer without a keyboard and monitor when I install the operating system? For media, I can use either the DVD or an ISO on the USB, so am good there. But how do I see what I am doing and enter commands without a monitor or keyboard? I have a Window 7 laptop, an XP laptop, and a CentOS laptop. Can I use one of my laptops to act as the MMI (Man Machine Interface)? If not, what is the easiest and least expensive option? Thank you

• Can Acrobat 11 be made to do OCR using multiple CPU cores?

  - by tarcman.

  OCR processing takes time. Using multiple CPU cores would speed up processing. Acrobat 10 was not a multithreaded application. How about Acrobat 11? Does 11 by default do OCR using multiple CPU cores (if available)? If not, are there any workarounds, e.g. scripting, to help make Acrobat 11 do OCR using multiple CPU cores? Either through Acrobat's built in scripting language or using external scripts that launch and direct multiple single thread instances of Acrobat to in parallell to parts of the processing job. Note: This question is not too localized (not limited to a specific moment in time) because (1) Adobe does not release new major Acrobat versions very often (Acrobat 10 was released two years ago) and (2) Adobe Acrobat is a widely used application.

• Amazon EC2 EBS volume scheduled backup/snapshots using puppet / similar tools

  - by Ehrann Mehdan

  I am not a Linux admin, although I wish I was, and I have seen these questions Amazon EC2 Backup Strategy Amazon EC2 + EBS:: Regular backup plan? Simple Backup Strategy for Amazon EC2 instances / volumes? And this suggestion http://alestic.com/2009/09/ec2-consistent-snapshot I tried using command line + crontab (the command line works, but crontab for some reason, doesn't) But I'm still pretty lost, all I want is an automated, rolling backup of my amazon EC2 (EBS) data (by rolling I mean keep 3-4 weeks back, but delete old snapshots as new ones come for cost control) And as things usually go, if there is something that is hard and painful, someone creates a solution for it. My question is simple, is there a way using a tool like Puppet to do it without a painful learning curve? (or via other tools like http://ylastic.com) If yes, how?

• Nginx user subdomains, should I proxy_pass?

  - by Kevin L.

  I am trying to setup user subdomains, serving content from specific folders: www.example.com/username served from username.example.com (just like github pages). I've looked at Nginx rewrites, but I don't want the browser to redirect--I want the domain to be username.example.com. Anyway, a comment on this question says that I cannot rewrite host, only proxy to it. I tried to setup a proxy_pass, but all of the documentation and examples show it being used to (obviously) proxy to a service on another host or port, but in my case I want to just proxy to another location on the same host and port. Is this the appropriate way to tackle this problem, and if so, what is the right Nginx config syntax?
