• How do people type different languages into computer?

  - by pecker

  Hello, We have English keyboards. I never saw any other keyboard in my life. I've been wondering for a long time. How do people in Korea, China, Russia, Muslim countries and some European countries where English is less known. Do they have keyboards in their native language? I mean are the keyboard directly manufactured in their native language. Or do they use some kind of keyboard mapping softwares to acheive the task. I've been searching in Google images to have a glance at their computers but didn't find any real key pads for computers/smartphones. If they have some non-English keyboard. Then how would they type web URLs? URLs possible in other languages also? If they have to type English URLs then it also means that they need to know English. I've seen in some movies that they have all their softwares, windows have text in their native language. How do they have some different language? I feel lost & confused. If you have any screenshots / pics of such non-english computer please post. I want to see one.

• Laptop Synaptics Touchpad No Longer Functional After Windows 7 Upgrade

  - by Chance

  I have a Toshiba laptop, with an integral Synaptics (PS/2 port) touch pad, that I bought pre-installed with 32-bit Windows Vista. After doing a clean install of 32-bit Windows 7, I can no longer get the touch pad to respond. The function (FN) keys on the laptop still operate correctly, but they no longer display on screen when used. I have no way of knowing if the function key to enable / disable the touch pad is working correctly, although the function keys for dim / brighten display, as well as others, work fine. I have removed the device from the device manager and allowed it to reinstall with no success. I have removed the previous drivers and updated them with the current 32-bit Win7 compatible versions from Synaptics website, with no success. The Synaptics icon displays in the taskbar, and the touch pad is available in the Device Manager, both of which say the device is installed and working correctly. I have checked to make sure that the touch pad is enabled in the Synaptics menu, and have tried toggling enabled / disabled with no success. If anyone has any suggestions, or knows where I can find a solution, I would be very appreciative.

• Windows Server 2008 R2 Standard to Enterprise Problems

  - by boburob

  A few months ago I setup a Citrix XenApp cluster running on Windows Server 2008 R2 Standard Edition using the temporary 180 day license key. Recently the company bought a Windows Server 2008 R2 Enterprise DataCenter license. This means I need to upgrade the Windows edition from Standard to Enterprise. I attach the disk to the VM and start the upgrade process through XenCenter, it runs through all checks and unpacks all Windows files and seems to create a Windows Setup partition, it then reboots and trys to boot into this partition and I get a blue screen telling me to CHKDSK the hard drive with the following error message: STOP: 0x0000007B As XenApp is already setup and working I really do not want to go down the route of rebuilding this server (as I already had to do this once down to issues with XenApp). The server did have 8GB of RAM assigned to it, I have tried reducing this down to 2GB's as I read this can cause an issue. Also I can boot back into the Windows Server 2008 R2 Standard partition without any problems. UPDATE I have managed to get round the urgency by re-arming the license, giving me another 180 day trial..but would be nice to work out why this is happening!

• Outlook 2010 Crashing Unpredictably

  - by cbkadel

  Very often when I open up Outlook 2010 and start doing actions in it, it will hang and become non responsive. I have tried letting it finish, but it never does come back (up to 20 minutes of letting it try). I generally have to restart Outlook and try again. Usually after about an hour of doing this, Outlook somehow snaps out of it and works for the rest of the day. It's generally in the morning (though I doubt that's the key variable). Generally, the emails that cause problems are HTML/formatted, but not always. What I've done so far to troubleshoot: Install Latest Outlook Hotfix (I think Dec 14, 2010) Start Outlook in Safe Mode Neither of those steps seem to make a difference. Usually - after about 10-15 restarts of Outlook on any given day, then it starts working thereafter. My next step is to uninstall/reinstall Office 2010, but I'm hoping someone has seen this and knows what to do about it - though not sure. My configuration is like this: Microsoft Online Services (using Microsoft's Sign In App) - Connecting to Exchange I have two other Exchange accounts in this profile (new feature in 2010) connected through Outlook Anywhere. Life Meeting Conferencing Add In I've disabled the People tab/add in. I've disabled the "Send to Bluetooth" add-in. Not sure what else to do?

• Network update solutions for a company of ~20 (5 local, 15 remote)?

  - by Margaret

  Hi all This is probably going to be a bit up in the air, because we're still in the "reaching towards solutions" phase, but I figured I'd see what you guys had to say. Plus I honestly know very little about systems and what is good and bad pratice. My organisation has always more or less worked on the concept of local machines; since it primarily employed contractors who were working from home, each of those people was largely responsible for their own machine and backup procedures and the like. We're now expanding, though we're still reasonably small (we're up to about 20 staff members). Most people still work remotely, but we have a central office where about five people are working. But we're getting large enough that we're starting to think it would be a good idea to have a central file server, and things like that - if someone gets hit by a bus, we want someone else to know where to look for the files to continue their work. A lot of the people who work for us remotely work on projects for other companies as well, so I don't want to force them to log in to our server whenever they're on a network. But I do want to make connection to be as painless as possible to do so, to improve utilisation. The other thing is that we're getting more people who would like to remote into the office server and do their work there. Our current remote connection application is an SSH install that allows people access to the network; the problem is, it's a black box to me, and I've never understood how to even connect to it (despite supposedly being de facto sysadmin). Thus far I've been able to bounce questions about how to get it working to the guy who does know it well, but he's leaving the company soon. So we probably need a solution for this that I actually understand. We were knocking around the idea of implementing a VPN with some form of remote desktop, and someone mentioned that this was largely a matter of purchasing a router capable of it; I'm not sure of the truth of that statement. This is what we have in the office: Two shiny new i7 servers, each running Windows Server 2008. Precise eventual layout is still being debated, a little, but the current suggestion is that one is primary database crunching, while the other is a warm backup of the databases, along with running Reporting Services. They currently have SQL Server 2008 installed on them, which is being connected to via the 'sa' account. We're hoping to make each person use their own account (preferably one tied to the 'central' password we set up, so we can use Windows Authentication). An older server, running XP Pro, that we are currently using as a test bed for a project that requires access to older versions of software. This machine is also being used to take backups, but I'm thinking of moving that functionality elsewhere. A spare desktop from a guy who left the company (XP Pro). We're thinking of bumping up the hard disk space and using it as the magical file server that's going to solve one particular everything. Assorted desktops, laptops, etc, at least one for each person in the office (mix of Win XP and Win 7; occasionally a person who normally works remotely might drop in to the office and bring a laptop bearing Vista, but it's pretty rare). All are set up as local user accounts at the moment; I don't know if it's the best arrangement. Purchasing more hardware is not a big problem, but we figure we might as well make use of what we've got first. Is Active Directory a big magic wand that's going to solve all the world's problems? Is there some other arrangement we should be looking to instead?

• How to change the mail domain server so it's not displaying IP? Changing [email protected] to [email protected]

  - by Pavel

  Hi guys. I'm kinda a noob as a server admin so please bear with me. I've installed postfix mail server and everything is working fine but the 'from' box is displaying [email protected]. I want to set it up so it displays domainname.com instead of IP. I just hope you know what I mean. My main.cf in postfix folder looks like this: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. myhostname = mail.thevinylfactory alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = mail.thevinylfactory.com, thevinylfactory, localhost.localdomain, localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all Can anyone help me with this one?

• How to fix high Load_Cycle_Count laptop drive (TOSHIBA MK6006GAH in Vaio TX1XP)?

  - by Sam Brightman

  Hoping someone knows exactly what's going on here. It seems this drive has some combination of aggressive power saving settings and Ubuntu defaults that has massively increased the Load_Cycle_Count for the drive: https://wiki.ubuntu.com/DanielHahler/Bug59695 So the drive is now so slow that it cannot boot because it takes long enough to access the data that the kernel will not recognise it properly. I'm not worried about the data on the drive, but would really like to keep the laptop functioning. There is some indication that this is possible because the figure is still low 200,000s and most drives supposedly go to 600,000. Additionally, SMART tests pass and consider the drive healthy and without errors. But the really surprising thing was when I ran mhdd... Every single read came up red (slow) until I pressed 'R' for reset drive. I noticed the next read was normal speed, so held down 'R'. Magically the drive read perfectly for as long as I held the key BUT resumed slow (and noisy) seeking/reading after releasing. I don't think the source code to mhdd is available, so I'm not exactly sure what this means (besides, I don't know enough low-level HDD stuff either). It seems like the drive should be able to work, but is stuck trying to power save or something. There are no BIOS options on the laptop. Does anyone know how I can stop the drive from doing extremely slow/noisy operations like this? Or is constantly resetting the drive also damanging, and only causing it to work well by luck (i.e. not a suggestion that it's fixable)?

• Recovery disk Windows 8 HP Pavilion g6

  - by fpghost

  I recently purchased a HP Pavilion g6 laptop running Windows 8. I want to either obtain the Windows 8 ISO or make some kind of recovery disk that would allow me to restore the system if things go wrong. The HP Pavilion comes with the 'HP Recovery Manager' which I thought may do the job, but on running it and putting in a DVD-R as requested it seems to just hang for a number of hours without doing a thing (the disk sounds like it's spinning for a few minutes but then goes silent). I then tried 'recdisc.exe' but I get the error System Repair could not be created The device reported unexpected or invalid data for a command. (0xC0AA02FF) Next I obtained my Windows 8 product key using the software ProduKey thinking this would allow me to go to the Microsoft website and download the Windows 8 ISO, but as far as I can tell all that is available is the upgrade which can be used if one is running something like Windows 7. Can anyone advise? EDIT: after a reboot recdisc.exe did work; I think the problem was due to some Windows updates needing a reboot, but never the less I would like a full Windows 8 ISO if possible.

• How do I restrict access to certain web files/folders on an IIS 7.5 based web server?

  - by cpuguru

  We're moving a website that was previously hosted on Win2k3 & IIS 6 to a Win2k8 R2 & IIS 7.5 platform. The website is public, but we want to restrict anonymous access to certain files and folders such that the user would be prompted for a password to access them. If this were Apache, a simple .htaccess file would serve the purpose. However, since it's IIS 7.5 and we're serving up mainly static HTML files and a few classic ASP pages I'm in a bit of a quandry as to how to restrict access to individual files and folders for various committees such that attempts to committee_1's files and/or folders would prompt the user for a password and, if entered correctly, would serve up their files. Same thing for committee_2 and so on. Under IIS 6, we would take away the read privileges for IIS_IUSRS and create a user called "committee_1" with a password known by the group and give that user read privileges to the files/folders. There's got to be a better (and more secure) way. Reminder, these are not *.aspx pages that are being served up. Any suggestions on how to password protect key files and/or folders under IIS 7.5 are much appreciated.

• Remote Desktop leaves host unresponsive

  - by Jeff Dalley

  I have my desktop PC at home set up to accept remote connections, and I often connect to it from work on my laptop via mstsc.exe. However, every time I remote to it, I find when I go home that despite the monitor being on - it's not receiving an image and it looks as though the computer is hibernating/asleep. I basically have to restart it whenever I get home and I know there's an answer for why its doing this. More details: When exiting the remote session, I have tried both logging off the account, and closing the RDP window without logging off; both give the same result. When I get home to the desktop I of course try moving the mouse, ctrl+alt+del to see if its responsive to restart, multiple key-press to see if I can get any audio out of it; It seems pretty obvious its sleeping/hibernating in some way: Nothing happens in any of these cases and a physical restart is necessary. Both desktop and laptop are running Windows 7 Ultimate. I'm thinking it really is sleeping/hibernating it, and I'm not sure why because left alone my desktop's power options are set to never turn off the HDD or change its state - I leave it on 24/7. This could be a stupid error on my part but I just can't see it! Thanks.

• If I ssh to a domain provided by dyndns, does my password go through them?

  - by D Connors

  I'm running Ubuntu on my work PC, and my work place provides me with a static IP address but not with a domain. It's sometimes useful for me to connect to that PC through ssh, but it's not common enough for me to instantly remember the IP number. So I set um a dyndns account, and associated a short and intuitive domain name to that IP. Here's my question, when I try to ssh to the domain, it asks me $ ssh [email protected] The authenticity of host 'something.there.foo (xx.xx.xx.xx)' can't be established. RSA key fingerprint is 'ALPHANUMERIC STRING' Are you sure you want to continue connecting (yes/no)? That surprised me a little bit. I have already registered the RSA fingerprint by connecting directly to the IP address. I thought the domain name was simply a convenient way of pointing me in the right direction (i. e. the ip address), but that message makes me think my data is actually going through their servers or something. Which one is it? Am I sending my password through someone else's server? Or is ssh just really really careful, thus warning me even if the final destination is a know host? The ssh server I'm using is the openssh-server package.

• Why is my rsync so slow?

  - by iblue

  My Laptop and my workstation are both connected to a Gigabit Switch. Both are running Linux. But when I copy files with rsync, it performs badly. I get about 22 MB/s. Shouldn't I theoretically get about 125 MB/s? What is the limiting factor here? EDIT: I conducted some experiments. Write performance on the laptop The laptop has a xfs filesystem with full disk encryption. It uses aes-cbc-essiv:sha256 cipher mode with 256 bits key length. Disk write performance is 58.8 MB/s. iblue@nerdpol:~$ LANG=C dd if=/dev/zero of=test.img bs=1M count=1024 1073741824 Bytes (1.1 GB) copied, 18.2735 s, 58.8 MB/s Read performance on the workstation The files I copied are on a software RAID-5 over 5 HDDs. On top of the raid is a lvm. The volume itself is encrypted with the same cipher. The workstation has a FX-8150 cpu that has a native AES-NI instruction set which speeds up encryption.

• Multiple SSL certificates on Apache using multiple public IPs - not working

  - by St. Even

  I need configure multiple SSL certificates on a single Apache server. I already know that I need multiple external IP addresses as I cannot use SNI (only running Apache 2.2.3 on this server). I assumed that I had everything configured correctly, unfortunately things are not working as they should (or maybe I should say, as I expected them to work)... In my httpd.conf I have: NameVirtualHost *:80 NameVirtualHost *:443 Lets say my public IP is 12.0.0.1 and my private IP is 192.168.0.1. When I use the public IP in my vhost my default website is being shown instead the one defined in my vhost, e.g.: <VirtualHost 12.0.0.1:443> ServerAdmin [email protected] ServerName blablabla.site.com DocumentRoot /data/sites/blablabla.site.com ErrorLog /data/sites/blablabla.site.com-error.log #CustomLog /data/sites/blablabla.site.com-access.log common SSLEngine On SSLCertificateFile /etc/httpd/conf/ssl/blablabla.site.com.crt SSLCertificateKeyFile /etc/httpd/conf/ssl/blablabla.site.com.key SSLCertificateChainFile /etc/httpd/conf/ssl/blablabla.site.com.ca-bundle <Location /> SSLRequireSSL On SSLVerifyDepth 1 SSLOptions +StdEnvVars +StrictRequire </Location> </VirtualHost> When I use the private IP in my vhost everything works as it should (the website defined in my vhost is being shown), e.g.: <VirtualHost 192.168.0.1:443> ...same as above... </VirtualHost> My server is listening on all interfaces: [root@grbictwebp02 httpd]# netstat -tulpn | grep :443 tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 5585/httpd What am I doing wrong? If I cannot get this to work I cannot continue to add the second SSL certificate on the other public IP... If more information is required just let me know!

• How to verify that a physical volume is encrypted? (Ubuntu 10.04 w/ LUKS)

  - by Bob B.

  I am very new to LUKS. During installation, I tried to set up an encrypted physical volume so that everything underneath it would be encrypted. I chose "Use as: physical volume for encryption," the installation completed and I have a working environment. How can I verify that the PV is indeed encrypted? I was never prompted to provide a passphrase, so I most likely missed a step somewhere. At the end of the day, I'd like whole disk encryption if that's possible, so I don't have to worry about which parts of the file system are encrypted and which aren't. If I did miss something, do I have to start over and try again, or can it be done (relatively easily?) after the fact? I would prefer not to introduce more complexity by using TrueCrypt, etc. Environment details: The drives are md raid1. One volume group. A standard boot lv. An encrypted swap lv using a random key (which seems to be working fine). Thank you in advance for your help. This is very much a learn-as-I-go experience.

• Is 40+ Logons on Exchange 2003 per user normal?

  - by cbsch

  Hello! We've had a problem at work where users sometimes randomly can't connect to exchange. I've found out that it's because they reached the limit of 32 concurrent logons. I increased the maximum allowed connections by adding the key "Maximum Allowed Sessions Per User" in HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem. But I'm not sure if this is a real good fix. Looking at the logons some users has as many as 15 logons with the exact same logon time. I know for sure that Outlook 2007 does this, as I was watching them while a user connected with Outlook after a restart on the Exchange service. Every user also has an iPhone connected to exchange, I don't know if these cause the same thing. Is this normal? Could there be a bug in the software? (The Outlook 2007 has nothing configured, except added the user, pure vanilla installs). The users are mobile, and when Outlook generates up to 15 connection every time it connects, and I've read (no sources, sorry) that Outlook doesn't time out connections before 2 hours. I might have to set this number real high to prevent it from being a problem.

• Security Token for Mac/Linux/Windows, self-managed, pref. open source?

  - by DevelopersDevelopersDevelopers

  I'm looking to buy an evaluation security token (combined smart card/usb reader) for my business that works on: Windows 7 x64 OS X 10.6.x x64 Ubuntu Linux (64 or 32 bit, 10.04 or 10.10, I can bend based on possible tokens) Functionality I need is: Login authentication Authentication for whole-disk encryption (in Linux/Windows, Mac is flexible here) Signing/encryption using PGP and x.509 certificates RSA-2048 key-capable (1024 not good enough.) I can manage the certificates myself Open source middleware/drivers (not necessarily FOSS, just source available. Can flex on this, I just want to be able to audit the code. OpenSC-compatible on Linux would be great.) Is there any token that can do all of this? Or would I need multiple ones to accomplish this? Or do I need to look at smart cards and readers to get this? I have been researching this for a while and have had a heck of a time even getting accurate information about products. Also, I am in the USA, and it appears that EU export laws prevent me from buying from there, so those vendors are out. I was looking at Feitian tokens from Gooze, but since they are in France I can't buy.

• Allow members of a group to be unlocked by a specific account on AD

  - by JohnLBevan

  Background I'm creating a service to allow support staff to enable their firecall accounts out of hours (i.e. if there's an issue in the night and we can't get hold of someone with admin rights, another member of the support team can enable their personal firecall account on AD, which has previously been setup with admin rights). This service also logs a reason for the change, alerts key people, and a bunch of other bits to ensure that this change of access is audited / so we can ensure these temporary admin rights are used in the proper way. To do this I need the service account which my service runs under to have permissions to enable users on active directory. Ideally I'd like to lock this down so that the service account can only enable/disable users in a particular AD security group. Question How do you grant access to an account to enable/disable users who are members of a particular security group in AD? Backup Question If it's not possible to do this by security group, is there a suitable alternative? i.e. could it be done by OU, or would it be best to write a script to loop through all members of the security group and update the permissions on the objects (firecall accounts) themselves? Thanks in advance. Additional Tags (I don't yet have access to create new tags here, so listing below to help with keyword searches until it can be tagged & this bit editted/removed) DSACLS, DSACLS.EXE, FIRECALL, ACCOUNT, SECURITY-GROUP

• Formatting not retained in paste from Ditto (clipboard manager). Plain text pasted instead [Solved] Add supported types

  - by Jeff Kang

  I'm trying to use Ditto on the Ditto documentation. If I were to copy the table of contents, then paste it (without Ditto) to the word processor, I get http://i.imgur.com/V1GU3.png, and the formatting is maintained. As as a result of the copy operation, the table of contents also goes into the Saved Items List (= History List = Lists the Clips saved from the Clipboard) in Ditto’s Main Window: I open a blank document to paste from Ditto instead of the default clipboard, and press either Ctrl-`, the default Ditto window activation Global Hot Key, or click the tray icon. From this point, I can do 3 things to close the Ditto window, and place the item on the clipboard (the default clipboard?). Select the item, and press Enter Put the cursor on the item, and double-click Select the item, and press Ctrl-c 1) and 2) send a right-click where the cursor is, after the Ditto window closes (presumably to have the paste option ready to access?): Ctrl-c just closes the Ditto window. Whichever method is used, the contents are pasted in what I believe is plain text: http://i.imgur.com/mQAZH.png How do I keep the formatting that the default clipboard keeps? Thanks.

• Anyone have a script to delete a specific local windows profile?

  - by Jordan Weinstein

  I'm looking for Powershell (preferred) script, or .CMD or .VBS, to delete a specific user profile on a workstation (WinXP) or terminal server (2000, '03 or '08). I know all about the delprof utility... That only allows you delete based on a period of inactivity. I want a script to: prompt admin for a username delete that username's profile and to delete the entire profile - registry hive too (not just the folder structure within Documents and Settings). The same way it would if you went to My Computer Properties Advanced tab User Profiles Settings and deleted profiles from there. Any ideas? All I can think of is doing an AD lookup to get the SID of the user specified, then using that to delete the correct registry hive too... something simpler would be nice though... Basically, my HelpDesk used to be local administrators on our Citrix servers and a common fix for various issues was for them to delete a user's profile on the citrix server(s) and have that user log back in - voila, whatever issue they had was resolved. Going forward, in new Citrix environment, they will no longer be local admins on those boxes, but still need to be able to delete profiles (deleting the entire profile: folder and reg hive is key). thanks.

• zsh : How to list directory content with tab?

  - by Philippe CM

  I just switched from BASH to ZSH and thing are pretty good, but: when I start typing cd /usr/share/s and hit TAB, this is what I get : $ cd /usr/share/sane/ sane/ skype/ ssl-cert/ screen/ smplayer/ strigi/ seed-gtk3/ snmp/ synaptic/ sgml/ software-properties/ system-config-printer/ sgml-base/ soprano/ sysv-rc/ sgml-data/ sounds/ simple-scan/ splashy/ And this is ok. If I then hit TAB again, I get $ cd /usr/share/screen/, the next candidate, witch is also OK. (BTW, how do I cycle back to the previous candidate? Sorry, on to my question) Now what if I want to see the contents of /usr/share/screen/ now ? You now, BASH-style? The cursor is at the end of the line, will I have to ctrl-a (or home), then del del (to erase cd) then ls then ENTER? That seems like a lot of typing. (And it - possibly unnecessarily - enters the command in the history) Would not there be a key (maybe modifier-TAB? but the obvious candidates are already taken by the desktop... I digress) that would tell zsh to stop cycling through /usr/share/ and instead, just list the content /usr/share/screen/ ?

• Mysql: create index on 1.4 billion records

  - by SiLent SoNG

  I have a table with 1.4 billion records. The table structure is as follows: CREATE TABLE text_page ( text VARCHAR(255), page_id INT UNSIGNED ) ENGINE=MYISAM DEFAULT CHARSET=ascii The requirement is to create an index over the column text. The table size is about 34G. I have tried to create the index by the following statement: ALTER TABLE text_page ADD KEY ix_text (text) After 10 hours' waiting I finally give up this approach. Is there any workable solution on this problem? UPDATE: the table is unlikely to be updated or inserted or deleted. The reason why to create index on the column text is because this kind of sql query would be frequently executed: SELECT page_id FROM text_page WHERE text = ? UPDATE: I have solved the problem by partitioning the table. The table is partitioned into 40 pieces on column text. Then creating index on the table takes about 1 hours to complete. It seems that MySQL index creation becomes very slow when the table size becomes very big. And partitioning reduces the table into smaller trunks.

  I'm new to Ubuntu (installed it for the first time just a couple of days ago on my server). I've Ubuntu Server 10.04 and am just using the terminal, no GUI like Gnome. So far it's working pretty great except for one big thing. Whenever I go to sleep and there's no activity on my server (it's not a big site so active users drop to 0 during the night), the server kind of disconnects. The only thing that can bring the site back online is to restart the whole server. I've tried disabling powersaving by using setterm but that changes nothing. Even if I wake up the server by pressing any key or so the site wont go back online! I've tried just restarting both Apache and MySQL (I'm using LAMP-server btw) but not even that works. But as soon as I turn the power off and on at the server, everythings work like normal for a couple of minutes of inactivity (~5-15 minutes I'd guess) and then it's down again unless someone logs in to the site and is active. I was previously using XAMPP on my laptop with Windows XP and that worked 24/7 so I don't think it's anything with my router or ISP. This is driving me crazy! My site is down all the time I'm in school as I have no possibility to restart the server if it becomes offline. Does anyone have a clue to what could be wrong?

• Where does Windows store MSI files for uninstallation?

  - by Nilzor

  I'm trying to figure out how Windows (XP through 7) is handling installation and uninstallation of MSI files. I have come up in situations where Windows Installer is unable to uninstall because it's missing the original MSI file, which leads me to believe that it stores a copy of all installed MSI packages somewhere. Where? I've had a couple of theories. It expectes it to reside in the same folder as it was installed from. The registry keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall does point to the original installation folder, and error messages when the MSI file is missing often point to this. Removing the MSI file from this folder does not hinder the uninstallation process though, so I've refused this theory. C:\Windows\Installer. This folder actually contains a bunch of seemingly randomly named MSI files. But this list is incomplete. I do find entries in the registry key mentioned in 1) which does not have an MSI copy in this folder. So how does this work? How is windows installer able to uninstall MSI-installed applications even though the MSI is not in 1) and not in 2)?

• How to prevent the command prompt from closing after execution?

  - by Sk8erPeter

  My problem is that in Windows, there are command line windows that close immediately after execution. To solve this, I want the default behavior to be that the window is kept open. Normally, this behavior can be avoided with three methods that come to my mind: Putting a pause line after batch programs to prompt the user to press a key before exiting Running these batch files or other command line manipulating tools (even service starting, restarting, etc. with net start xy or anything similar) within cmd.exe(Start - Run - cmd.exe) Running these programs with cmd /k like this: cmd /k myprogram.bat But there are some other cases in which the user: Runs the program the first time and doesn't know that the given program will run in Command Prompt (Windows Command Processor) e.g. when running a shortcut from Start menu (or from somewhere else), OR Finds it a little bit uncomfortable to run cmd.exe all the time and doesn't have the time/opportunity to rewrite the code of these commands everywhere to put a pause after them or avoid exiting explicitly. I've read an article about changing default behavior of cmd.exe when opening it explicitly, with creating an AutoRun entry and manipulating its content in these locations: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor\AutoRun HKEY_CURRENT_USER\SOFTWARE\Microsoft\Command Processor\AutoRun (The AutoRun items are _String values_...) I put cmd /d /k as a value of it to give it a try, but this didn't change the behaviour of the stuffs mentioned above at all... It just changed the behaviour of the command line window when opening it explicitly (Start-Run-cmd.exe). So how does it work? Can you give me any ideas to solve this problem?

• How do I back up Hyper-V VMs with Windows Server backup on Windows Server 2008 R2?

  - by Chris

  I've searched this site and google, and I CAN find information about how to back up Hyper-V virtual machines by using Windows Server Backup from the Hyper-V host in Windows Server 2008. You have to set up a registry key to enable the Hyper-V VSS writer, and then you can take online backups of your VMs. However, all the information I have found is about a year old, and none of it has been updated for Windows Server 2008 R2. I tried to run the "FixIt" .msi found here: http://support.microsoft.com/kb/958662 ... but it said that it was not applicable to my operating system. So I am thinking either Windows Server 2008 R2 already has its VSS service for Hyper-V enabled, or it still needs to be enabled but the FixIt package doesn't feel comfortable operating on an OS that wasn't RTM at the time. I went ahead and scheduled a windows server backup for 9pm tomorrow. It said it would take 86 GB, which means it MUST be counting those VMs. But will this backup fail? Can anyone confirm whether you have to apply the same registry changes for R2?
