• IIS 7.5 returning 404 for unknown host names

  - by WaldenL

  This just doesn't seem correct to me, so I'm looking for someone to tell me how I've misconfigured IIS... Configuration is IIS7.5 (2008R2), without SP1. I have IIS 7.5 configured w/several sites. ALL sites have hostnames defined in the bindings, there is NO site w/out a hostname. However, if I request an unknown hostname from the server IIS (technically Microsoft-HTTPAPI/2.0) return a 404 error, not a 400 error. I would expect a 400 (or some other major error) rather than a lowly 404. This causes a problem when I have nginx in front of multiple IISs and want to stop a site so nginx takes it out of rotation. Since IIS still returns a 404 for the request even when there is no active site for that name, nginx doesn't know the server is dead. NB: IIS returns the 404 regardless of whether there is a server, but it's stopped, or there is no server. Thoughts? Solutions? -- Additional info: OK, I added a site on a port other than 80 (5000) and then on a connection to that port asked for a site that doesn't exist, and I get the expected error 400 (Invalid hostname). So, while IIS isn't listening for generic (no host name) connections on port 80 it would seem that something is. Any ideas how to get HTTPSys to dump the list of what it's listening for?

• Selectively allow unsafe html tags in Plone

  - by dhill

  I'm searching for a way to put widgets from several services (PicasaWeb, Yahoo Pipes, Delicious bookmarks, etc.) on the community site I host on Plone (currently 3.2.1). I'm looking for a way to allow a group of users to use dangerous html tags. There are some ways I see, but I don't know how to implement those. One would be changing safe_html for the pages editors own (1). Another would be to allow those tags on some subtree (2). And yet another finding an equivalent of "static text portlet" that would display in the middle panel (3). We could then use some of the composite products (I stumbled upon Collage and CMFContentPanels), to include the unsafe content on other sites. My site has been ridden by advert bots, so I don't want to remove the filtering all together. I don't have an easy (no false positives) way of checking which users are bots, so deploying captcha now wouldn't help either. The question is: How to implement any of those solutions? (I already asked that on plone mailing list without an answer, so I thought I would give it another try here.)

• Linux - preventing an application from failing due to lack of disk space [migrated]

  - by Jernej

  Due to an unpredicted scenario I am currently in need of finding a solution to the fact that an application (which I do not wish to kill) is slowly hogging the entire disk space. To give more context I have an application in Python that uses multiprocessing.Pool to start 5 threads. Each thread writes some data to its own file. The program is running on Linux and I do not have root access to the machine. The program is CPU intensive and has been running for months. It still has a few days to write all the data. 40% of the data in the files is redundant and can be removed after a quick test. The system on which the program is running only has 30GB of remaining disk space and at the current rate of work it will surely be hogged before the program finishes. Given the above points I see the following solutions with respective problems Given that the process number i is writing to file_i, is it safe to move file_i to an external location? Will the OS simply create a new instance of file_i and write to it? I assume moving the file would remove it and the process would end up writing to a "dead" file? Is there a "command line" way to stop 4 of the 5 spawned workers and wait until one of them finishes and then resume their work? (I am sure one single worker thread would avoid hogging the disk) Suppose I use CTRL+Z to freeze the main process. Will this stop all the other processes spawned by multiprocessing.Pool? If yes, can I then safely edit the files as to remove the redundant lines? Given the three options that I see, would any of them work in this context? If not, is there a better way to handle this problem? I would really like to avoid the scenario in which the program crashes just few days before its finish.

• DDoS nulling to some ips and other options?

  - by Prix

  I am looking for some information in regards DDoS in the follow scenario: I have a server that is behind a Cisco Guard and it will be DDoS'ed, I only care about a set list of IPS that by not means are the attackers. Is it possible to null all other ips but this list to actually get any response to my server or in the long run no matter what I do if they have enough DDoS power I will just go down like a flie ? Is there any recommended company out there that can actually cope with a DDoS ? My server will mainly run several clients that will get connected to a external server and all it needs access to is my local MySQL the the private network so I can access it. There will be no other services runnings such as web or ftp etc at least not to the external ips of the server if i ever have to have any of these service they will be on the private network. The MySQL will be available externally only to 1 safe ip not known by anyone but me and internally at localhost + private network. Are there any solutions ?

• Own server, multiple website: most secure PHP setup

  - by plua

  Hi there, We have a company server with a variety of websites. They are maintained by different people from within our company. All websites are public. The server access is limited to our company only. This is NOT a shared hosting environment. We are looking into securing the server, currently analyzing the risk related to permissions of files. We feel the highest risk is when files are uploaded and then opened/executed by the public. This should not happen, but an error in a script might allow people to do so (there are image uploaders, file uploaders, etc). Uploader scripts use PHP. So the question is: what is the best way of setting / organizing permissions of files and processes? There seem to be several options to run PHP (and Apache), and setting the permissions. What should we take into consideration? Any tips? We are considering mod_php and FastCGI, but perhaps given our situation other solutions are preferred?

• Running phpmyadmin xampp Ubuntu 12.10

  - by Luigi Tiburzi

  I know it is a common problem and there are many solutions on the web but I'm trying everything and anything is working, I can't have phpmyadmin running on my machine. I installed XAMPP through: sudo tar xvfz ./Downloads/xampp-linux-1.8.1.tar.gz -C /opt then I did the chmod trick supposed to make an end to access issues and I change the default location to my php projects from /var/www to Dropbox/php. Then I started XAMPP in the usual way: sudo /opt/lampp/lampp start When I tried to run one of my php projects the output on the web is fine but if for example I try to write localhost on my browser I get: It works and not the usual XAMPP interface and most of all when I try to access localhost/phpmyadmin I get the login page, insert username (root) and password and I get: You don't have permission to access /phpmyadmin/index.php on this server. Apache/2.2.22 (Ubuntu) Server at localhost Port 80 I tried the Required all granted trick and some others but nothing is working. I even tried to uninstall phpmyadmin and reinstall it but this is not working too. I don't know hot to proceed. Thanks for your help.

• Setting the default permissions for files uploaded via FTP to a directory

  - by Kerri

  Disclaimer: I'm just a web designer/coder, and server admin stuff is my weakest point of them all. So be easy on me (and very specific). I'm using a simple CMS (Unify) on a site, where part of the functionality is that the client can upload files to a specified directory (using FTP). The permissions for the upload directory are set to 755. But when files are uploaded through the interface, they are uploaded with permissions set to 640 (instead of 644), so site visitors cannot acces the files. When I emailed the CMS's support about this, they told me that it was a server setting, and I need to make sure that files uploaded through FTP are set to 644. Makes perfect sense, but I have no idea how to do this. Any help would be greatly appreciated. This site is a shared site hosted by Network Solutions (Unix), so my access options are limited. I can edit .htaccess files, and php.ini, but that's about all I have access to. It appears I can't even log on via shell. ETA: 11/11/2010 Thanks all. I was able to work around this problem by setting up the CMS's settings in a different way. I'd be interested in following up on Nick O'Niel's suggestions, because I think he's on the right track, but unfortunately I can't access the necessary files on this particular server. So, anyway, I'm leaving this open, since the original questions isn't exactly resolved. Unfortunately, I probably can't put a correct answer to the test, since the shared server in question has nearly all of its config files tightly locked down.

• Monitoring AWS Systems Behind ElasticBeanStalk

  - by A. Avadis

  So I'm getting a company set up in the Amazon Cloud -- creating IAAS protocol/solutions/standardized implementation, etc while also being the SysAdmin for individual systems, app environments, and day-to-day uptime. One of the biggest issues I'm having is tracking various system/application logs, as well as logging/monitoring/archiving system metrics like memory usage, cpu usage, etc etc In a centralized fashion. E.g. -- Nagios + Urchin. The BIGGEST impediment to my endeavors is the following: The company application is deployed in the form of a Java *.WAR file, uploaded to an Elastic BeanStalk application environment, load balancing and auto-scaling between 3(min) and 10(max) servers, and the EC2's that run the application are fired up and disposed of ad-hoc. That is to say, I can't monitor the individual EC2's for very long because so many are being terminated then auto-provisioned/auto-scaled on the fly -- so I'd constantly be having to "monitor what I'm monitoring", and continuously remove/add EC2 machine addresses to my monitoring lists. IS there some sort of way to use monitoring tools like Zabbix or Nagios to monitor the ElasticBeanStalk, and have it automatically add on new EC2's, and remove terminated/failed EC2's from its monitoring list automatically? Furthermore, is there anything I can do with GrayLog to achieve similar results with the aggregation/centralization of my application logs from multiple EC2 instances into ONE consolidated set of logs/events? If not GrayLog, is there ANYTHING LIKE GrayLog that can automatically detect what EC2 members are being added/removed from the environment, and collect the logs from them automatically? Any and all advice or direction is appreciated. Thanks much, and cheers!!

• Windows 7 remote desktop encryption error every few minutes

  - by rfrankel

  Because of an error in data encryption, this session will now end. This is the error I've been getting more and more frequently over the past few days, to the point that I can't ignore it because it's happening consistently within 5 minutes of connecting - sometimes within a few seconds. Both the remote and local machines are Windows 7 Pro x64. The remote machine is behind a Linksys RV082, and I'm using UPnP to forward a remote port to the correct local port. This setup had been working fine for several months, and I can't think of any recent relevant changes that might have been made. Things I've already tried: Disabling unnecessary components of the network connection on the remote machine, until only IPv4 and Client for Microsoft Networks remain. Disabling TCP large send offload on both the remote and local machines. Confirming that the remote machine is not mentioned anywhere in any DMZ settings on the Linksys router. Confirming that there are no x509-related registry keys screwing things up (this is the suggested fix for a slightly different error anyway). These are the only solutions I've been able to find after about an hour of searching, and most of them apply to XP or Server 2003 in any case. If anyone could suggest something else, it would be much appreciated.

• Is there a better way to do bonded vlan tagged interfaces with XEN

  - by AJ01

  We have a number of XEN servers all running CentOS or RHEL. The VM's that they run are all required to be on their own VLAN for no other reason than the customer expects them to be. Long story short however, I can't change this right now. We are also required to have bonding enabled on the interfaces. So to accommodat this we enslave eth1 and eth2 to bond0. We then create a seperate interface called bond0.VLANID where VLANID corresponds to the correct vlan; eg ifcfg-bond0.204 DEVICE=bond0.204 BOOTPROTO=static ONBOOT=yes VLAN=yes BRIDGE=xenvlan204 Bridge to XEN As you will see, we eventually have to bridge this out to XEN, and we do this by adding another interface called xenvlan204 (in this instance) which contains; ifcfg-xenvlan204 DEVICE=xenvlan204 BOOTPROTO=none ONBOOT=yes TYPE=bridge XEN Vm Config Finally in our XEN config for each VM, we add vif = [ "bridge=xenvlan204" ] This then allows the vm host to access that particular vlan The Problem We've noticed a few problems with this setup. One being that we currently create the interfaces manually. Which means if we add more vlan enabled interfaces and bridges we usually have to restart xend which is something I'm not so hot about. Also lower level staff have their heads melted by the number of interfaces and the risk of a mistake occurring is high. Secondly, it can take sometime for a host to come up if it has a number of vlan taged interfaces. Thirdly, its just not scaling well on the management aspects The Question Is there a better more flexible way to do this (in particular with Xen that ships with centos 5.3, 5.4 and 5.5 as we have to support all three) that leverages either scripting or other solutions to allow an arbitrary amount of interfaces to be created when a vm is instanced. Your advise and expertise is more that welcomed.

• Execute remote shell commands on windows XP embedded

  - by BartD

  The following situation: We have Windows XP Embedded clients that have all admin shares disabled and only have read-only shares (for security reasons). What we want to do is run remote shell (dos) commands on these machines. At first we looked at PsExec & BeyondExec applications (and all sorts of variants), but all of them rely on having at least an admin$ share, which are disabled on our systems. Telnet is not secure enough, as is RSHD servers. So we looked at the next obvious solution: and SSH server. We also prefer an open-source or freeware solution that is still maintained. I looked at freeSSH server for Windows, but that didn't run stable, I tried installing copSSH, WinSSH & openSSH for Windows, but none of these applications seem to work on Windows XP Embedded. The services can either not be installed or cannot be started. I don't know why. Some kind of dependency that is missing. So are there any other solutions out there? I don't care about having to an agent installation locally of some kind on each system, as long as the size of the software is small enough. Can someone suggest some alternatives to what I've already mentioned? Thank you very much.

• How to have a shell script available everywhere I SSH to

  - by aib

  I have a shell script which I simply cannot do without: bar from Theiling Online I use SSH a lot and on a variety of *nix servers. However, I am not a system administrator and usually don't have the time or privileges to install it on every server I connect to. It is apparently a very portable sh script and has command line options to export itself as a shell function, which got me thinking: Could I use one of OpenSSH's subjectively obscure features to export it everywhere I go? My first thought was to assign the source to an environment variable like BAR = "cat -v" and then execute it on the other side as `$BAR`, but 1) I can't even get the cat example to to work locally, 2) I don't know how to put the script's actual multiline source into an environment variable and 3) I have yet to see a machine with PermitUserEnvironment enabled. I guess I could even do with an ssh option to write a file called ~/bar at logon, but a more volatile solution would be better. Calling wget http://.../bar at logon would be unacceptable. Any ideas? P.S. Putty-specific solutions, though I doubt any would exist, are also fine.

• Dell Latitude D510 Runs From Battery But Not AC Adapter

  - by Jason George

  I have a Dell Latitude D510 that went belly up around two years ago. It will run from the battery, however, the wall adapter will neither power the machine nor charge the battery. Once the battery is dead, the machine is dead. Since it died I've searched repeatedly for solutions. I've tried a new AC adapter and even removed and replaced the DC jack thinking one of the solder joints might be bad. Both to no avail. After two years of searching I finally found the answer today. Since it's such a simple fix and I had such a hard time finding it I wanted to post the info for others (as it is apparently a common issue with the D510). -----SOLUTION----- It seems this is commonly caused by a cracked solder joint at pin 1 on an inductor filter pair (FL2) near the power jack. Pins 1 and 4 are ground and pins 2 and 3 are power. There should be 20V from 1 to 2 and 3. Anything less indicates a cracked joint that is increasing resistance and dropping the supply voltage. Repair simply requires reflowing all four pins with a little added solder for security. Detailed instructions can be found here. Dell Latitude D510 solder problem

• How to share text, pictures and video to restricted set of users

  - by joaoc

  I want to share pictures and videos of my kid growing up but I don't want it to be open to the public. I just want me and my wife to be able to add material and then share with grandparents and friends who would be given a username/password or some other solution that authenticates them. This content would preferably be available remotely over the internet or downloaded periodically to the allowed viewers computers. The second option most likely means they would have to install a client, which I am not too fond of doing (I would have to ask them to install it, help configure for different platforms, ...) I'm at the start but I would like software that also allows export of the data (if one day I want to migrate to a different solution). Folder sharing I don't know if Windows folder sharing is reliable, robust and safe enough to share over the internet. Dropbox could be a software solution, but it's limited to 2GB and requires receivers to also install and configure software. A folder is just a collection of files, so it would be harder to keep them organized with text describing the pictures/video Email I could email the content every now and then but videos are almost always too big to go as attachments This would also not provide a history of updates to anyone just recently joining in Are there other solutions to achieve this? NOTE: I also thought that software to run a local or remote blog could be an option but we aren't allowed to ask those questions on superuser because one admin doesn't like cloud-computing questions. But if you do think it's the best approach and can suggest a solution, do state it in the answers anyway!

• effective back-up using Raid / Win7 back-up

  - by Job

  I have a stand-alone pc system with two 2 tb harddiscs, one of which configured as Raid1, i.e. mirorring. The operational drive is partitioned. I use an external 1 tb harddisc for back-up using Windows 7 back-up facility which will be swapped weekly and stored on other premises. I back-up all partitions AND allow a system back-up. All application software is on the C: partition. Questions: How can I see whether Raid1 is working; i.e. is doing its job. All I see now is a status message in the start-up procedure that says its status is normal. How can I see used or available space on Raid 1? The Win-7 backup allows for 1 schedule only as far as I can see. I want daily back-ups of data. However due to the single schedule I am forced to do the time-consuming system back-up and c: back-up as well. Is there a way to activate two schedules allowing a frequent (daily) data back-up and a system back-up with c: drive back-up on a say weekly basis? Of course it can be forced by hand but I am likely to forget that. I am not the programming type of person so looking for simple and controllable solutions. Thank you - any help is apreciated.

• Windows Explorer Hangs on Right-Click

  - by Bryan

  I am not sure if this is the right site to post this one as I typically post coding questions on stackoverflow. But I'll ask anyways and hopefully someone can move it if it's incorrect. Currently I have a customer built PC, utilizing an Intel i7 chip, 1300WATT PSU, 8Gigs of RAM, and two video cards. Originally I had the one video card (NVIDIA) that used the PSU and had two DVI output. After purchasing a third monitor I installed another ATI) graphics card not needed any PSU connectors. After installing and restarting, I noticed that when I right-click on my desktop, or through Windows Explorer it will hang, freeze then restarted. Sometimes after Windows Explorer restarts the problem dissipates. I checked to make sure everything was connected properly and it was. I repaired the ATI Catalyst Control Center to see if that had an issue, and I checked to see if either video card required updated drivers. Nothing worked. I tried restarting my PC and that didn't work. I tried using ShellXView (I forgot what it's actually called) and tried closed processes but that didn't work. Does anyone have any idea what could have caused this orpossible solutions I should try?< Thanks in advance.

• One server with multiple desktops "heads" with VNC

  - by Alexis K

  I am managing a system of kiosks. Each kiosk currently is running a web browser with the application for the kiosk running in the browser. Each kiosk needs to be able to display separate content. At times, the application running in the web browser freezes. Thus, I have to go out to the site to refresh the page. I want to see if there is a way to have one central server that has multiple browser heads. Then each kiosk would run a program like VNC to display one of the heads. This way when the program freezes, I just have to login to the central server and refresh the page. Getting VNC or another remote desktop software installed on the clients is no problem. What I am looking for is a way to have VNC remote into a specific head of a head of a web browser. Does such a thing exist? Or do I have to run a VM for each kiosk to remote into? Any advice, pointers, or solutions would be helpful.

• Backup solution to backup terabytes and lots of static files on linux server?

  - by user28679

  Which backup tool or solution would you use to backup terabytes and lots of files on a production linux server ? Note that the files are all different and almost never modified, and usage is mostly adding files, so data volume is today 3TB growing all the time at around +15GB/day. Please do not reply rsync. Basic unix tools are not enough, rsync does not keep history, rdiff-backup miserably fails from time to time and screw the history. Moreover these are all file based backup, which put a lot of IOwait just to browse directories and query stat(). But i guess, except R1Soft CDP, there is no way around that. We tried R1Soft CDP backup, which is block level backup, and it proved good and efficient for all our other servers, but systematically fails on the server with 3 terabytes and gazillions of files. That is already more than 2 months that the engineers of R1Soft and datacenter are playing a hot ball game... and still no backup except regular rsync We never tried big commercial solutions, except R1Soft CDP since it was provided as an optional service by the datacented hosting our servers.

• Using VMware Guest OS to enable Host OS to ssh to remote network

  - by Reuben L.

  Basically I have an issue because my host OS is 64-bit Linux Mint (Ubuntu derived) and it doesn't seem to be compatible with the Juniper Network Connect that is used by the network at my workplace. Thus, I am unable to ssh from terminal to the network. I can't make changes to the workplace network either so that leaves me with looking for solutions on my end. The main reason for me to access the network from home is to check on my running processes or to issue more commands to a few workstations. Putty is the desperate choice I usually make but it means I have to reboot to Windows and also have limited control. I've tried several other methods and they have all failed. Recently, I setup a VM with Windows 7 as the guest OS. Now half my problems are fixed as I don't have to physically reboot the system - I just have to engage Juniper Network Connect on the VM. However, I would still like to use my Linux terminal to ssh to the network. It sounds plausible that I could somehow manipulate ports to connect to the remote network from the host OS tunneled through the guest OS, but I really have no clue how to do so... Can anyone help?

• Give access to specific services on Windows 7 Professional machines?

  - by Chad Cook

  We have some machines running Windows 7 Professional at our office. The typical user needs to have access to stop and start a service for a local program they run. These machines have a local web server and database installed and we need to restrict access to certain folders and services related to the web server and database for these users. The setup I have tried so far is to add the typical user as a Power User. I have been able to successfully restrict them from accessing certain folders (as far as I can tell) but now they do not have access to the service needed for starting and stopping the local program. My thought was to give them access to the specific service but I have not had any luck yet. In searching the web for solutions the only results I have found relate to Windows Server 2000 and 2003 and involve creating security templates and databases through the Microsoft Management Console. I am hesitant to try an approach like this as these articles are typically older and I worry this method is outdated. Is there a better way to accomplish the end goal of giving the user permission to run the service and restrict their access to certain folders? If any clarification is needed on the setup or what we are trying to achieve, please let me know. Thanks in advance.

• How do I fix error 1303 during TI Connect install?

  - by smoth190

  I recently purchased a TI-84 Plus graphing calculator, and I'm trying install the TI Connect software in order to connect the calculator to my computer via the USB cable. Unfortunately, I'm getting this error while trying to install the program: Error 1303. The installation has insufficient privileges to access this directory: E:\Data\Timothy\Documents\MyTIData. The installation cannot continue. Log on as administrator or contact your system administrator. However, my account is the only account on my PC, and it has administrative privileges. I've also tried running the installer with Run as Administrator, but with no luck. If I create the folder MyTIData manually, I receive this error: Error 1317. An error occurred while attempting to create the directory: E:\Data\Timothy\Documents\MyTIData I've reapplied the security settings to the E:\Data folder (and all its sub-directories) to Full for my account. I've also gone into Computer Management, and given SYSTEM full privileges for the entire disk. I've also logged out, logged back in, restarted, etc. but still, no luck. Now, I should mention that my Documents folder is not at the default location. I changed it due to my C: disk being a 90GB SSD, so I moved all my personal data onto the extra storage disk (which is ~1TB). I don't know if that is causing the issue, but it can't hurt throwing it out there. So why can't I install this program? Google'ing the problem brings up this error for various other installers (such as Visual Studio and Microsoft Office), but nothing for TI Connect. All the solutions are the same: Give the folder Full privileges...but I've already done this! I've also tried running the installer with and without the calculator plugged in, but it didn't change anything. In the prompt that contains the error, repeatedly clicking Retry or waiting a few moments before clicking Retry also produces no result.

• How to back up a database with thousands of files

  - by Neal

  I am working with a Fedora server that runs a customized software package. The server software is quite old, and its database consists of 1,723 files. The database files are constantly changing - they continually grow and changes are not necessarily appended to the end. So right now, we currently back up every 24 hours at midnight when all users are off of the system and the database is in an internally consistent state. The problem is that we have the potential to lose an entire day's worth of work, which would be unrecoverable. So I'd like to know if there is a way to take some sort of an instantaneous snapshot of these database files that we could back up every 30 minutes or so. I've read about Linux LVM snapshots, and am thinking that I might be able to do accomplish the goal by taking a snapshot, rsync'ing the files to a backup server, then dropping the snapshot. But I've never done this before,so I don't know if this is the "right" fix. Any ideas on this? Any better solutions? Thanks!

• organizing my music and my itunes

  - by Cawas

  What can we do to organize our music? I've got over 20k items on my iTunes Library, at least 5k with ratings and play counts, apparently just 12k music files and I can't understand how this question have not been properly answered yet. Maybe there is no answer. I have too many duplicates, broken links, bad music, corrupted files... Well, a big mess with no tags! Probably there's no single software capable of just organizing everything, though I'd love one. Hopefully some time in the near future we all will be able to just sync the cloud of our automagically selected music to the newly created offline copy. But meanwhile... Please, do consider I've at least gave a shot (even while not a full test drive) to every single answer linked here already, plus a few more. I'm fine with using other software (mac too, please) to organize, but I'd need it to sync (retrieve and put back) at least iTunes ratings, because of iPhone and smart playlists. Not looking for iTunes replacement. I'm hoping to hear what you hardcore music organizers out there are using as your own solutions! :) I myself am using way too many tools, getting way too little done and end up going song by song.

• How can laptop keyboard keys be removed and replaced?

  - by Lord Torgamus

  I'm trying to fix a laptop keyboard that has issues with keys on its left side. Just by feel, it's clear that something sticky got under there. There could be something crunchy too, but that might just be the sound of the key's spring releasing itself from the sticky. I don't know the cause because it's not my computer and the owner isn't sure, but I'm guessing soda spill for now. The computer is an HP dv2500. I've removed the keyboard and blown under it but that hasn't helped. I didn't use compressed air because I just don't have any available, but I suspect it wouldn't help with sticky. So, I'd like to pop they keys off and clean with damp cotton swabs or similar. Is there a proper way to remove the keys? I've found some instructions via Google for non-laptop keyboards, but they don't seem like they'd work for me. Alternate solutions to the problem also welcome, but I've been curious about how to remove the keys for some time for other reasons.

• Windows desktop virutalization instead of replacing work stations

  I'm head of the IT department at the small business I work for, however I am primarily a software architect and all of my system administration experience and knowledge is ancillary to software development. At some point this year or next we will be looking at upgrading our workstation environment to a uniform Windows 7 / Office 2010 environment as opposed to the hodge podge collection of various OEM licensed editions of software that are on each different machine. It occurred to me that it is probably possible to forgo upgrading each workstation and instead have it be a dumb terminal to access a virutalization server and have their entire virtual workstation hosted on the server. Now I know basically anything is possible but is this a feasible solution for a small business (25-50 work stations)? Assuming that this is feasible, what type of rough guidelines exist for calculating the required server resources needed for this. How exactly do solutions handle a user accessing their VM, do they log on normally to their physical workstation and then use remote desktop to access their VM, or is it usually done with a client piece of software to negotiate this? What types of software available for administering and monitoring these VM's, can this functionality be achieved out of box with Microsoft Server 2008? I'm mostly interested in these questions relating to Server 2008 with Hyper-V but fell free to offer insight with VMware's product line up, especially if there's any compelling reasons to choose them over Hyper-V in a Microsoft shop. Edit: Just to add some more information on implementation goals would be to upgrade our platform from a Win2k3 / XP environment to a full Windows 2008 / Win7 platform without having to perform any of that associated work with our each differently configured workstation. Also could anyone offer any realistic guidelines for how big of hardware is needed to support 25-50 workstations virtually? The majority the workstations do nothing except Office, Outlook and web. The only high demand workstations are the development workstations which would keep everything local.
