• Determining who is running with administrator rights?

  - by Alex C.

  I work at a small non-profit organization with about 55 desktop PCs running Windows XP Pro. The domain controller is running Windows Server 2003. I have a two-part question (note that I'm a bit of a newb when it comes to network administration). Part 1: Is there some simple way that I can determine which accounts are logged in with administrator rights? Part 2: Is there a way that I can remove administrator rights from users without sitting down at each individual machine? Thanks for considering my questions.

• Is it safe to use S3 over HTTP from EC2, as opposed to HTTPS

  - by Marc

  I found that there is a fair deal of overhead when uploading a lot of small files to S3. Some of this overhead comes from SSL itself. How safe is it to talk to S3 without SSL when running in EC2? From the awesome comments below, here are some clarifications: this is NOT a question about HTTPS versus HTTP or the sensitivity of my data. I'm trying to get a feeling for the networking and protocol particularities of EC2 and S3. For example Are we guaranteed to be passing through only the AWS network when communicating from EC2 to S3 Can other AWS users (apart from staff) sniff my communications between EC2 and S3 Is authentication on their api done on every call, and thus credentials are passed on every call? Or is there some kind of authenticated session. I am using the jets3t lib. Feedback from people with some AWS experience would be appreciated. Thanks Marc

• Good Linux Distro for Disconnected Netbook

  - by MrWizard54

  I'm deployed to Afghanistan with the Army and I have a friend who's netbook had his hard drive take a dump on him. He ordered a new hard drive and I was able to download and burn a copy of Ubuntu to disk from work. However the default install doesn't support most of the media that he wants to watch (AVI files, probably some DIVX video) without installing extra packages. We don't have internet in the tent and really don't have a vaiable option for downloading additional packages through the package manager anywhere here. The computer is a small HP netbook. All my friend wants is to watch ripped movies. Does anyone know of a good way to do either of the following: Download packages seperately and install them via CD A distro that is going to come preloaded with all of the packages and needed to watch just about any type of video file you can think of? Thanks in advance, Andy

• Purging old Exchange email/content on SBS2003

  - by Aitch

  We have a Windows SBS 2003 server that used to manage email, calendaring and such like for a small organisation via Exchange. We successfully migrated everything to Google Apps for Business about 18 months ago. The server only provides local network services now. We have backed up and virtualized this machine and would now like to purge any residual mail to save disk space and speed up backup etc. The disk space is such that I believe the Exchange mail is still on there somewhere. I've stumbled through System Manager and poked about but cannot confirm whether this is the case. Where would this live and how might I go about it? (Disclaimer: I'm not a Windows admin, Linux is my thing...)

• Additional mailboxes in Outlook 07 SP2

  - by Nick

  I have had my Outlook 2007 open additional mailboxes via the advanced account settings. After updating to Office SP2, the list of emails in the additional account still displays, but I get a message for each mailbox item: This item cannot be displayed in the Reading Pane. Open the item to read its contents. After double clicking the message, I get a small error box which displays just Cannot open this item. Unknown Error. Also, if I try to re-add the mailbox in the Advanced tab of my account settings, I get an error message The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action. However, the status bar indicates Online with Microsoft Exchange, and I can both send and receive emails from my primary account. What could be going wrong?

• Sizing a Virtual Server

  - by vdubs

  I would like to replace four aging physical servers with one virtual server. What is the best way to insure the VM server is sized correctly? The requirements of the apps that will be running on the four servers are APPLICATION SERVERS - QTY 3 - These will run the application layer for the web server, Business Objects Business Intelligence app, and various other small client server apps. The three most heavy hitting apps each have the following server requirements. So, if I bought three physical servers, this would be the requirements for each of them Processor - Dual 2.83 GHZ (or faster) Ram - 4 GB Raid 5 - 50-100GB usable space NIC - 1 GB Web Server - this will run one asp.net e-business app that will talk to our dedicated SQL server and the three app servers above. The E-Business software has these requirements for the web server Processor - Quad 2.83 GHZ (or faster) Ram - 8 GB Raid 5 - 50-100GB usable space NIC - 1 GB What is the best tool to determine what I need from a hardware standpoing in a virtual server? I am planning on using VMWare.

• What's the strategy to implement a "knowledge base" in my company. [closed]

  - by Oscar Reyes

  In my current work we think we can get benefit from having a knowledge base, so the next time someone has a question/problem etc, that base can be consulted and an answer will show up. Also, it will reduce the risk from having people leaving the company with the knowledge and we would have to start all over again. My question is, what strategy can we follow to implement/buy/get/build/etc this knowledge base? Are there software ready for this? Would it be better to have something build by ourselves ( we have some programmers ) This is an small company ( < 30 ) and the base should be accessible from outside the office ( when the employees are with the customer etc.) so I guess a webapp is in order.

• Run one virtual machine on a Linux server + standard Linux functions

  - by fistameeny

  Hi, I am looking for a method to setup a Linux server (running Ubuntu Server) that uses Samba for file sharing, as well as hosting a Windows virtual machine (in this case, Windows Small Business Server 2003, which in turn hosts SQL Server Express - Exchange won't be used on this). I would like to have the Linux server serving the files over Samba, and hosting the Virtual Machine. This obviously rules ESXi out as it couldn't do Samba at the same time. What would be the next best solution to give reasonable speed? Vmware Server 2.0, VirtualBox, Xen? There will be 10-15 users accessing the Samba shares and the SQL Express virtual machine. Matt

• Ubuntu issues when moving hard disk to new system

  - by Tim

  I'm working on a legacy project with a small single board computer running Ubuntu 10.04 on a compact flash card. I need to be able to save away a working image (via dd) and copy said image to other compact flash cards for use in other single board computers (with identical hardware) I'm able to copy the image to other flash cards and bootup on other systems no problem. But I'm seeing strange behavior. For instance, I can't use sudo on the new system (“sudo: must be setuid root”). I've gone down the path of trying to fix this, but have run into a slew of other issues. General question is: what do I need to be aware of when moving a hard disk containing Ubuntu (in my case a compact flash card) to another computer? I was hoping it would be seamless to Ubuntu since it's moving to a system with identical hardware. Is there something that needs to be done to make it "portable"?

• Automatically select last row in a set in Excel

  - by Luke

  In Excel 2003, I am trying to keep track of some petty cash, and have it set up with the denomination along the top row, along with a sub total and difference column. I want a small section that shows how many rolls of coins I should have, by taking the total amount, and dividing it by however many should be in a roll, and rounding to the lowest whole number. That part is fine. What I want done is for that ONE section (how many rolls) I should have, based on the last row that has information in it. For example, if the last row is row 13, it should read the data from B13, C13, D13, etc. I don't mind learning Macros, if that's what the solution requires. I don't want to be manually selecting the last row each time though, I just want the worksheet to know automatically.

• auto copy newest folders and images in MyPictures folder to USB drive

  - by TVersmet

  I drop lots of photos in a day into the My Documents/My Pictures folder. I archive at the end of each day to USB drives, to be stored offsite. What I would like is someway to automate the process. By example, a small app or script I can simply double-click and it will scan the My Pictures folder for the newest folders and images and copy them to the USB drive until the drive is full. It doesn't matter if I get redundancy from the previous days saved images, so long as the newest images and folders are always the first to get copied. Well, that's my request. Thanks for reading.

• Nearest PC equivalent to Mac Target Disk Mode?

  - by username

  Mac firmware has a special boot mode that allows you to offer its internal hdd to another computer as an external disk (you just connect the two machines via an IEEE 1394 cable). Only the second machine needs a functioning OS installed. Any good suggestions for something similar on the PC side of things? Block level access isn't important to me, I'd just like to be able to copy files off it. It doesn't matter to me if it uses Ethernet, IEEE 1394, or wifi - I just like having a quick way to access files on a client PC. Is there any single-purpose Linux distro specially designed to do this? It'd be nice to have something super simple, quickbooting, and small that I could install on a USB drive. I used to use Knoppix, but it's overkill as a Target Mode replacement.

• Is there any descent open-source search engine solutions?

  - by Nazariy

  Few weeks ago my friend asked me how hard is it to launch your own search engine service with list of websites that suppose to be crawled time to time. First what come at my mind was Google Custom Search however pricing policy is quite tricky and would drain your budget if you reach 500K queries per year. Another solution I found here was SearchBlox, which can be compared to Google Mini service. It's quite good solution if you planing to cover search over small amount of websites but for larger projects it is not very handy. I also found few other search platforms like Lucene, Hadoop and Xapian which seems to be quite powerful solutions to reach Google search quality, and Nutch as a web crawler. As most of open-source projects they share same problem, luck of comprehensive guidance of usage, examples and it's expected that you are expert in this subject. I'm wondering if any of you using this solutions, which of them would you recommend, and what should I be aware of?

• No GUI after upgrade to Ubuntu 9.10 (boots to command line)

  - by Gathris

  I have just upgraded to Ubuntu 9.10 (network upgrade using the update manager, from 9.04 which had different graphics related problems) and when I try to boot into it all I get a small Ubuntu logo, flickering text and then the tty1 command line with a logon prompt. startx gives following error: Fatal server error: no screens found I traced down a tutorial that said I needed the latest graphics drivers (Gigabyte ATI Radeon 4650 HD installed with 9.10 catalyst drivers) so I did using the 'sh' command and a USB stick (I have a working Windows partition) and it installed fine but did not fix the problem. Edit: Thanks to UK and Arjan van Bentem below I was able to understand the full error message of start x: Parse error on lone 2 of /etc/X11/xorg.conf 'nameserver' is not a valid keyword in this section Fatal server error: no screens found This has nothing to do with a graphical error (sorry if I misled anyone) but the xorg.conf file has 3 lines in it and lines 2-3 have an entry 'nameserver'. Using the nano command I commented out (using a # before the entries) the nameservers and can now boot Ubuntu. Thanks to everyone for their help.

• SCVMM upgrade scenario

  - by pigeon

  I've read some information on TechNet about upgrading SCVMM 2008 - 2012 but can't quite figure out the best way to approach this. The current setup is that we've got SCVMM 2008 R2 installed but against best practice it was actually installed on the Hyper-V host machine since its a small scale deployment its just a single server setup with SCVMM existing on the same host rather than be in a VM. So from what I've read an in-place should be possible which will incur a restart but also don't have the luxury of another server to shift the VMs onto whilst doing this or want to risk anything happening to the Hyper-V role. Ideally I would probably prefer just to get SCVMM 2012 into a VM of its own and remove the 2008 version from the host machine. Anyone done an upgrade on this or have any recommendations about how to approach this?

• Increase text size in Ubuntu due to having large resolution/monitors

  - by Sridhar Ratnakumar

  I have 24" dual monitors with 1920x1080 resolution on both of them. Consequently the text appears so small. I use the following text-intensive applications frequently: Web browser (Google Chrome) IDE (Komodo) Terminal (Gnome Terminal) Email (Thunderbird) I can configure text size on IDE, Terminal and Email. But for Chrome, it is not a good idea to set proportional font size because often one wants to see the entire (not just proportional fonts) site to be zoomed. So I am asking: Is it possible to increase DPI in Ubuntu (much like on Windows) so as to increase the text size across all apps? OR Is it possible to set permanent 'zoom' in Google Chrome, using a third-party extension maybe?

• HTTP Requests Fails for WordPress sites after upgrading from PHP 5.2 to PHP 5.3

  - by anjanesh

  I've upgraded from Ubuntu 9.10 to 10.04 beta 1 and PHP got upgraded from 5.2 to 5.3 Now all my WordPress & Magento sites arent working. I tried retrieving the URL headers from the command line, but HTTP request fails. Utilizing get_headers in a small script, PHP Warning: get_headers(http://local.vhosts1.com): failed to open stream: HTTP request failed! in get_headers.php on line 12 But HTTP request fails only for WordPress and Magento based sites - not custom written ones. Does this probably have to do with some htaccess directive ?

• Can the NVIDIA ION chipset handle streaming and gaming reasonable well?

  - by true_gritt

  I'm considering getting a small-footprint "nettop" computer to use as a home theater PC with my Samsung LN40A550 HDTV. I've been looking at systems like the AS Rock ION HT330, the Acer AspireRevo 3610, or the Asus EeeBox PC EB1501. These are all systems with NVIDIA ION chipset (Intel Atom N330 dual core CPU + NVIDIA GeForce 9400 GPU). Is the NVIDIA ION chipset powerful enough to support media streaming at HD resolutions (e.g. via Boxee, Hulu, Netflix) and casual gaming (e.g. World of Warcraft, Madden NFL) reasonably well without herky-jerky video output?

• What tools exist for generating "ASCII Tables", if any?

  - by Billy ONeal

  Consider a block like the following: +-----------------------------------+--------------------------+ | In Baseline | Not in Baseline | +---------------+===================================+==========================+ | In Parent # Do Not Report | Mark ACE as AlwaysReport | +---------------+-----------------------------------+--------------------------+ | Not In Parent # Iff parent depth > baseline depth | Report Always | +---------------+-----------------------------------+--------------------------+ I have seen tables like this used quite frequently. For instance, in Requests for Comments (RFC) documents, the standard format of the document is the text format. Another common case is embedding a small table like this into comments of source code. Are there tools which can take a quick and dirty representation of this in Excel, or possibly some textual format, and format it as a table like this?

• Moving SharePoint 2010 to a new domain

  - by Chris

  I have a small SharePoint 2010 farm (1 WFE / App Server & 1 SQL server) Our organisation is currently mirgrating to our holding company's global domain, so we now have a new local DC on site with trusts between the current domain and the new domain. I am going to need to move our SP Farm to the new domain and possibly rename servers to fit into the global naming convention (we are trying to avoid this at the moment, but might become a requirement) If there a way to script (stsadm / powershell) the user profiles and permission accross to the new domain? and on the server side, is it as simple as joining the servers to the new domain and updating all the service / farm accounts to accounts on new domain? I have googled this a bit, but everything I have found so far refers to MOSS 2007 or earlier. Any help / advise would be appreciated.

• Set up router to vpn into proxy server

  - by NKimber

  I have a small network with a single LinkSys router connected to broadband in US via Comcast. I have a VPN proxy server account that I can use with a standard Windows connection, allowing me to have a geographic IP fingerprint in Europe, this is useful for a number of purposes. I want to setup a 2nd router that automatically connects via VPN to this proxy service, so any hardware that is connected to router 2 looks as though it is originating network requests in Europe, and any hardware connected to my main router has normal Comcast traffic (all requests are originating from USA). My 2nd router is a LinkSys WRT54G2, I'm having trouble getting this configured. Question, is what I'm trying to do even feasible? Should the WRT54G2 be able to do this with native functionality? Would flashing it with DD-WRT allow me to achieve my objectives? Any help/suggestions much appreciated. Neil

• Vista: "connect to a network" does not load (can't set up VPN)

  - by Arkaaito

  I'm trying to connect to my office VPN from home. One small problem: my home desktop uses Vista (64-bit, Ultimate edition). On Vista, you're supposed to set up a VPN like so: Open the control panel Click on Network Click on "Connect to a Network" Configure a new connection of type "Office" The problem is, when I click on the link for "Connect to a Network", nothing happens. Can anyone suggest how I should go about troubleshooting this? (Or am I better off just upgrading to Windows 7?)

• How to setup a simple self-hosted dynamic DNS server

  - by Cerin

  I have a small internal network of physical machines running hypervisors, which in turn run several KVM Ubuntu virtual machines. How would I setup an internal dynamic DNS server so that when I run a script to create a new virtual machine, that VM could automatically register itself in the DNS server? Bind seems to be the standard DNS server for Linux, but it seems designed for a much more "static" DNS model. Dynamically updating this would require a complicated script that would have to SSH into the DNS server, edit configuration files, and then restart the server. This doesn't seem like a very elegant solution. Are there better options? I saw a similar question, although they're asking for a solution for a public setting on Amazon. My servers are entirely private, and I don't want to rely on an external VM host or Dynamic DNS provider.

• How have you saved green by going green?

  - by Bob

  For the purpose of this question, I am interested in server/datacenter related hardware. Have you had any measureable amount of ROI by swapping existing hardware to more "green" or energy efficient hardware? For example, VMWare says you can reduce energy consumption by up to 80% by using virtualization. I have also heard of a cooling solution from HP which is suppose to reduce a small amount of engery usage (<25% I think). Google has also done something by integrating a UPS into their power supplies to reduce energy consumption. Any real world experiences would be great, but if you have any details on initial cost, savings and pay off time about what changes were make that would fantastic. I am not only interested in virtualization, I am interested in anything.

• What is the most economic hardware that will run Ubuntu? [closed]

  - by nbolton

  I'm looking to buy the cheapest hardware I can find that will run the latest version of Ubuntu desktop on some sort of usable level (e.g. use of web browser, flash, etc). I guess small form factor would be pretty convenient, so I was looking at Acer Aspire Revo for example, but I'm not sure whether or not it's overpriced. I'd rather pay less for the same thing minus brand name if it's available. Any ideas? On further investigation, it seems I'm looking for a nettop.
