• How to remove the Ubuntu Gnome desktop after making the switch to KDE?

  - by codeLes

  This is the opposite of this question. Basically I've been using Ubuntu for a while but decided to give KDE a shot so I went through the process of getting the latest KDE installed. I'm very impressed with KDE and the Kwin window manager seems like a better WM than Compiz which is what I was using for Gnome (sure that's an oppinion). This was an Ubuntu Jaunty install. So how do I go about removing the Gnome desktop? Is there an automated way similar to what my previous question covered? UPDATE: Should there be any packages I should NOT remove in the process?

• Cisco IOS router config -- how to disable SSH / SNMP on all but loopback address?

  - by chris

  Sorry for the naive question; a quick reading of the cisco docs doesn't answer this question... So I've got a router (say for the sake of argument a 4500 running IOS 15.x) It has interfaces in 3 different subnets -- 10.0.0.1/24, 10.0.1.1/24, and 10.0.2.1/24 It also has a loopback address of 172.16.0.33 How do I make it so that SSH / SNMP and other administrative traffic works on the 172 address but doesn't work on the IP addresses I wish to only use for L3 forwarding? Ideally this can be done by disabling the control plane access to these interfaces not just by using an ACL, but whatever, I don't actually care that much as long as it works... Thanks!

• create replica of ext4 filesystem and re-use it

  - by Jatin

  Is there a way that I can use my Linux ext4 file system, as such and then use it on some other computer. I have a dual-boot of Windows 7 and Ubuntu 10.04 and my partition table looks like this: My question might not be clear, so explaining it with an example. Can I copy my Linux partition on a flash drive and then use it on a different PC, with or without any need to install Ubuntu on new PC, by simply booting from the copied ext4 partition. This way, I can easily port my Ubuntu packages and other applications, settings etc. from one PC to other. If it's a very stupid question, please don't mind.

• I get regular power surges and my UPS ticks a lot due to a welding plant. Is this good or bad?

  - by EApubs

  In our home, there is a mechanic who often use a welding plant. When he use it, I think we get a power surge. My UPS ticks madly (not beep, it ticks). Sometimes, I even lose power to the keyboard. When typing, some keys get missing. 1) My question is, is it good for the computer? The UPS claimed to have surge protection. But isn't it working? What should I do to protect my PC? 2) The second question is, I also have a broadband router which is not connected to the UPS. Will it be effected?

• VLC without chrome in Windows

  - by timberwo7ves

  I'm trying to run VLC (2.1, 64 bit) without any chrome on Windows 7. You can achieve it by going to Preferences, and in the Interface tab, unchecking Integrate video in interface, and also in the Video tab, unchecking Window decorations. The problem lies in the fact that without Window decorations there is no apparent way to move or resize the video window - in GOM player, for example, you can move window by dragging on the video itself; is there an option for this in VLC? Ideally, I would like to move the window by the method described above (by dragging the video), and would like the Window decorations to reappear on mouseover, to allow resizing; I'm a new VLC user, but unsure how far the customisation goes. - I'd settle with just the moving of the window via dragging the video if this is possible by advanced setting. There is a similar question here, but not exactly, and no solution to that particular question.

• How to disable VGA on new server... reversibly?

  - by Javawag

  Strange question here. I have a server with 1GB of RAM, however when booted this shows as 768MB. I've discovered the reason for it – and that is that it has an unboard graphics card which shares memory with main RAM. Running Ubuntu Server, it doesn't actually ever use anything graphical – it's all set up to be SSH'd into and therefore there's no need to use the VGA. I believe there may be a setting to switch off VGA/graphics card in BIOS, but my question to you guys is: is this recommended? and if I turn it off, then how would I turn it back on again in BIOS (given that with it off, I wouldn't be able to see the option to turn it on as there would be no graphics output!!)?

• Invoking an MMC Snap-in function from Windows command shell: is it possible?

  - by robob

  Sorry for the cross post on Superuser, but I cannot see any answer to my question, so I try to ask the same question here. I need to execute a MMC Snap-in function from the Command Shell of a Windows computer. I need it to schedule this command in the same Windows PC and executes in background. Probably this questions could seem a little bit strange but I have a program that creates a debug log only through its MMC Snap-in console. And I need to automatise this task to programatically read this log! Dows anyone know how to do this? thanks

• Installing a 3.5" hard drive in a 2.5" bay?

  - by Javawag

  I know this question seems ridiculous, but my server (actually a Mini-ITX computer) has a 2.5" hard drive bay and an empty CD-ROM bay underneath it. If I removed the hard drive bay, I could probably mount a 3.5" hard drive in the CD-ROM bay which is unused... I know it's a big of a kludgy way to do things but it does mean upgrading the hard drive to 2TB is much cheaper. My question is: are the power requirements of a 3.5" disk the same as 2.5" one? I know the connectors physically will still fit, but I don't want to destroy my server!

• How to choose which fields are available via LDAP from an Active Directory

  - by Felix Eve

  I'm using PHP to do an ldap search and then pull the attributes out using ldap_get_attributes. This returns an array of data (that can be seen here) however there are some fields that are missing such as Organization Title, department, company, address and telephone number. How to I make these fields available? There is a similar question here: http://www.petri.co.il/forums/showthread.php?t=15227 I've followed the steps outlined there an tried changing some access permissions but am not really sure what I'm doing and can't see any permissions that directly relate to the fields that I can see when I edit a user in the "Active Directory Users Computers" window. I am a PHP developer, not a Windows server administrator so am finding configuring an AD rather challenging so please don't assume any level of knowledge about AD. I've asked the same question on stack exchange but understand this is a more relevant place to ask.

• Hosting several domains on one server using IIS 7

  - by Øyvind Knobloch-Bråthen

  I have created several web sites inside IIS7 on my server. All of them use the same ip and port, but different host names. Currently I have set the host name to www.mydomain.com. Now my question is, how do I get my actual domains to target the different sites on my server. Second question. Can I set my host name to only mydomain.com to make sure that all requests to that domain is handeled by the same application? Primarily, I want both www.mydomain.com and mydomain.com to work when the user types the address in their browser.

• Providing high availability and failover using MySQL on EC2

  - by crb

  I would like to have a highly-available MySQL system, with automatic failover, running on Amazon EC2 instances. The standard approach to solving this is problem Heartbeat + DRBD, but I've found a lot of posts suggesting DRBD doesn't work on EC2, though none saying exactly why. Obviously, a serial heartbeat or distinct network is out of the question in the virtualised environment. It would also be good to have the different servers be in different availability zones, but we're getting into a much harder problem there. What are peoples' opinion on having a high uptime solution in "the cloud"? Note: This question was asked before RDS with multi-AZ was announced, which is the nice automatic answer for today's modern IT professional. :)

• dig and dig -x are answering different

  - by erdemkeren

  I don't want the name provider to manage my records. I want to handle it myself. So I installed bind9 and made some configurations reading some articles and following some examples. bind didn't show any error after I created/edited the required files but; When I write `dig www.foo.com, I see the IP of the advertisement page of my name provider. But when I write dig -x server_ip_address; I see the name I purchased. What am I doing wrong? Can't a server be the nameserver of it's own? Is it a must to configure the records from the company I bought the name from? By the way, I realised that, my previous question was not clear, I deleted it, and asking the same question in a different way.

• Decreasing lagging on router, while gaming

  - by user2699451

  I had absolutely no idea where to post this question and get a professional answer for it but here goes... Okay, so I guess everyone whos is reading this had played online, and so I was playing LoL again tonight and my brother decided that now was a great time to go on youtube and start watching a movie, so my ping (connecting from South Africa to EU west server) is around 190-220 average, however it started spiking to 2000 and average was 600-800, so it arised the question, how ther hell can I "kick" him off for the time being I tried reasoning it out with him but its like playing chess with a pigeon, he's studying to be an engineer, and I just cant win an argument with him, so i need to step it up a level... I have in the past used the aireplay method by sending deauth packets but it only helped so much, is there another way of either kicking a peer of the local wifi or decreasing the lag spikes while in session or even splitting the bandwidth equally in 2 or 3,etc What do I do p.s. sorry if off topic, if it is not appropriate, just say which website will be able to help or assist me...

• Dynamic VPN tunneling technologies

  - by Adam

  Ok, so I'm asking a more specific question this time. I'm writing a paper about Cisco's DMVPN and one of the tasks I have is to make the analysis of available network solutions which use dynamic VPN tunnels. Because the paper is about DMVPN, I have to compare those solutions to it. I know there are a lot of dynamic tunneling technologies but I'm looking for ones that can be compared to DMVPN. So the question is: are there any technologies which use dynamic VPN tunnels (not necessarily using crypto) that can be compared to DMVPN? What are those technologies?

• Currently well suited SATA2-SSDs for Laptop usage

  - by danilo

  I am looking for a solid state drive for my laptop. My dillemma: I have been waiting for the new Intel SSDs since Q3/2010, as I've heard they should be better and cheaper, due to lower memory manufacturing costs. Now it looks like the new Intel drives are very fast, but still expensive. I would still buy one of them if I could benefit from the full speed. My hardware only has a SATA-2 port though. Thus, my question: Is it worthwhile to buy one of those new Intel SSDs made for SATA-3 if I won't be able to use the full speed? Are there any other promising new SSDs that will be released soon? (Inside the next 1-2 months) If I wouldn't make a good deal buying the newer, faster drives, what drives can you recommend? I don't consider this question subjective, as I am mainly looking for answers concerning the SATA-2/SATA-3 conflict.

• Remap key combinations in Windows

  - by nickf

  This question is similar to this one, but the accepted solution doesn't work in my case. I work on two different laptops. On one, the Home and End keys are only available by pressing Fn+Left and Fn+Right. This can make it rather annoying when switching between the two since I always go to press Fn-Right and not get what I want. The tool suggested in the other question is Sharpkeys, however it doesn't recognise Fn+Right as a different key from Right, and I suspect that registry twiddling isn't going to help me here. (?) Is there any way to remap this combination? (I'm on Windows Vista if that helps)

• What does advantages of WIM image that file based vs. ISO or another sector based images in Administrator

  - by saber tabatabaee yazdi

  answers of this question is very important to administrators to choose between Microsoft solution or other 3rd Party Tools. WIM solution is file based and others are sector by sector images like Acronis or other backup and clone tools like Norton Ghost or Cloning in vmware ESXi and etc. My question about the advantages of WIM to edit or deploy in Enterprise? to get agreements of managers to choose between these alternative decisions. Are we had any Key Performance Indicators in Change management? Are there any statistics about compares of these solutions? What Time is spend in any solotion to get image or change images or revert and apply images? Is it possible to change and modify images that made in All of these solutions as easy as in WIM file?

• 2nd/3rd version of wireless network appears

  - by neildeadman

  I replaced an old SpeedTouch ADSL router with a Netgear DG384 that I have and whilst doing so decided to change the wireless password. For this question assume my wireless network SSID is DeddersHome. On my netbook and macbook pro (running Win7) it won't connect to the Internet. When I hover over the tray icon for wireless it says "DeddersHome 2" and "DeddersHome 3" have no internet connection. What are these additional wireless networks? I can't see them in the wireless network list on any wireless device I have. Wired connections and wireless through my iPhone work fine. I saw this before with the SpeedTouch, but it just went away!! I also have one Apple AirPort Express connected to the wireless network which my Xbox is connected to (wired). This all worked before... I am going to remove AirPort to see if it is this causing the problem, but thought I'd ask the question to give it time for an answer whilst I continue to search. Cheers

• How do I remove a URL from Google without having to have a Google E-mail Account

  - by PP

  Really simple question. I do not want a Google account. I just want Google to stop making requests every 2 minutes for a URL it should never have known about (apparently Google harvests URLs from search requests as well as private e-mails, not just from actual web pages). But when I search Google help for removing URLs it appears I have to use their "webmaster tools" which require logging into a GMail account! How do I tell Google not to index my URL without becoming a customer? Note: I already return 404 for the URLs in question using a rewrite rule - this appears to make zero difference to the crawler which continually attempts to fetch the page every 2 minutes.

• Multiple columns in a single index versus multiple indexes

  - by Tim Coker

  The short version of my question is what's the difference between three indexes each indexing a single column and one index indexing three columns. Background follows. I'm primarily a programmer but have to do DBA work because we don't have a DBA. I'm evaluating our indexes versus the queries run against a particular table. The table as 3 columns that I'm often filtering against or getting the max value of. Most of the time the queries look like select max(col_a) from table where col_b = 'avalue' or select col_c from table where col_b = 'avalue' and col_a = 'anothervalue' All columns are independently indexed. My question is would I see any difference if I had an index that indexed col_b and col_a together since they can appear in a where clause together?

• Is the Zune HD's audio card better or worse than the iPod touch's?

  - by MatthewThepc

  Firstly, if this is the wrong site to ask this question I apologize, but I didn't see one for "music players" on the stack exchange website :) After reading a few people online say that music playing from a Zune HD sounds better to them than that on an iPod touch, I was wondering whether there's any truth to that? From what I can tell, the Zune HD uses a Wolfson Microelectronics WM8352, while the first-generation iPod Touch (which the Zune HD was competing with) used a Wolfson Microelectronics WM8758BG, and newer models use the Cirrus Logic CS4398 and CS42L61. Which ones are better (to make the question less subjective, let's say in terms of quality, range, & accuracy of output)? Admittedly, I have almost no idea how everything compares and works together, but it would seem to me that, just by looking at the version numbers, the iPod has been better since it's launch. Is there anything else that effects sound quality? Thanks!

• I want to virtualize my workstation (Tier 1), Looking for Bare Metal Hypervisor for consumer grade components

  - by Chase Florell

  I find myself in this similar bind at least once a year. The bind whereby I'm either upgrading a motherboard, or an OS hard drive. It drives me crazy to have to reinstall Windows, Visual Studio, all my addins, reconfigure my settings etc... every single time. I have a layout and I like and I want to stick with it. My question is... Is there a Bare Metal Hypervisor on the market that will enable me to virtualize my consumer grade workstation? I really want to avoid Host/Client virtualization. Bare Metal is definitely a better way to go for my needs. Is this a good approach, or am I going to suffer some other undesirable side effects by doing this? Clarification My machine has very limited purposes. My primary use is Visual Studio 2010 Professional where I develop ASP.NET MVC Web Applications. The second piece of software that I use (that's system intensive) is Photoshop CS3. Beyond that, my applications are limited to Outlook, Internet Explorer, Firefox, Opera, Chrome, LinqPad, and various other (small) apps. Beyond this, I'm considering working on a node.js project and might run ubuntu on the same hypervisor if possible. System Specs: Gigabyte Motherboard Intel i7 920 12 GB Ram basic 500GB 7200RPM HDD for OS 4 VelociRaptors in Raid 1/0 for build disk Dual GTS250 (512MB) Graphics cards (non SLI) for quad monitors On a side note I also wouldn't be opposed to an alternative suggestion if the limitations are too great. I could install the ESXi (or Zen Server) on my box, and build a separate "thin client" to RDP into the virtual machine. It appears as though RDP supports dual monitors. Edit (Dec 9, 2011) It's been nearly a year since I first asked this question. Since then, there have been a lot of great strides in Hypervisor technology... AND MokaFive is now released for corporate use. I'd love to dig into this question a little more and find out if there is a solid BareMetal Hypervisor for workstations running consumer grade components (IE: not Dell, HP, Lenovo, Etc).

• A complete tool for auditing and archiving emails would be helpful for the community?

  - by Renato Todorov

  Please, don't treat this like a discussion question, I'm looking for direct answers: Yes / No, because... I work on a financial company and I'm needing a tool for email archiving and auditing. The compliance sector is asking for it and I have to provide it. I've searched and found two solutions: MailStore (commercial, Windows only) and Enkive (open source, very poor UI and lack of features). I'm using Postfix as MTA and Courier for IMAP/POP access. I'm almost deciding to write it myself, I have the knowledge needed, but I'm wondering right now if it's worth to put (a lot) more hours to make it open source and user friendly. So my question is, have you ever had the same need? Would this be a helpful solution? Is there any other good tool that I haven't found? Thank you!
