• Cannot chown my own files from NFS

  - by valpa

  We have a NFS server provide home directory for many account, which provided by a NIS server. I have account A and B. In /home/A, I try to copy "cp -a /home/B/somedir ~/". Then I found in /home/A/somedir, all files are owned by user A. Then if I do "chown -R B:B somedir", I got "Operation not permitted" error. I am user A, "cp -a" didn't preserve the original user (B). Then I cannot chown my own files. Any suggestion? I fix my own issue by "chmod 777 /home/A", "su - B" and "cp -a somedir /home/A/", and "su - A", then "chmod 755 /home/A". But it is not a good solution.

• How to quickly save what is currently shown in cmd.exe to a file

  - by Zeiga

  I am asking if there is a quick way/command to save the current standard output from cmd.exe or powershell to a file. For example, I have run a bunch of commands in cmd.exe which generating like hundreds of lines of standard output. Ideally, I am looking for a single command to do "select all" and save to a file automatically. Note: I've read this. But I don't want to change my original commands, so "" or "" redirection cannot be used in this scenario. Thanks.

• Why some recovery tools are still able to find deleted files after I purge Recycle Bin, defrag the disk and zero-fill free space?

  - by Ivan

  As far as I understand, when I delete (without using Recycle Bin) a file, its record is removed from the file system table of contents (FAT/MFT/etc...) but the values of the disk sectors which were occupied by the file remain intact until these sectors are reused to write something else. When I use some sort of erased files recovery tool, it reads those sectors directly and tries to build up the original file. In this case, what I can't understand is why recovery tools are still able to find deleted files (with reduced chance of rebuilding them though) after I defragment the drive and overwrite all the free space with zeros. Can you explain this? I thought zero-overwritten deleted files can be only found by means of some special forensic lab magnetic scan hardware and those complex wiping algorithms (overwriting free space multiple times with random and non-random patterns) only make sense to prevent such a physical scan to succeed, but practically it seems that plain zero-fill is not enough to wipe all the tracks of deleted files. How can this be?

• How can I resolve this error when using net start / stop: "The service name is invalid" ?

  - by JosephStyons

  We have a server that hosts a service (I'll call it "tomato"). Up until now, a client pc has been able to start and stop this service. They just double-click a batch file, and inside that batch file is the command net stop tomato or net start tomato They recently got a new physical computer, and now those same commands fail with the error: C:\>net stop tomato The service name is invalid. More help is available by typing NET HELPMSG 2185. What do I need to do to let the client pc start and stop this service remotely? Edit: I mis-remembered the original commands. They were not using "net start" and "net stop" remotely. They were using sc \\server_name start tomato and sc \\server_name stop tomato And those commands to indeed still work.

• Windows 2003 Server - Can I map a folder to another folder on the same server?

  - by TheCleaner

  Scenario: I have a server that was running low on space. We have an external iscsi SAN that it now has a LUN on and connected to the server as E:\ We are moving the PHOTOS folder from the old location on D:\ to the new E:. That new drive is being shared out as "ARCHIVE". So: \server\shared\photos now becomes \server\archive\photos I can easily place a shortcut in the original location saying "DOUBLE CLICK HERE FOR THE PHOTOS", but it isn't ideal. What I'd like is to be able to have \server\shared\photos simply point to \server\archive\photos. So that if someone wants to map a drive to \server\shared and then browse to the photos folder once in there they will see what is in the \server\archive\photos location. Is that possible? I was thinking about SUBST or DFS, but I don't think either of those will do it.

• Can font substitutions in MS Word be controlled?

  - by Jukka K. Korpela

  Suppose that I am typing text in MS Word (any version) and I enter a character that does not exist in the font being used. Say, I’m using Times New Roman and I type 2300 Alt X, which turns to the diameter sign “?”, which does not exist in Times New Roman. MS Word picks it up from a different font, like Arial Unicode MS. This may mess up the typographic style, or line spacing. And this happens without notice. Perhaps the most inconvenient feature here is that MS Word does not automatically return to the original font. Subsequent text appears in the replacement font, unless the user sees what is happening and realizes that he needs to change the font. The question is: Can such substitutions be controlled, e.g. by specifying the font(s) to be used as backup fonts? If not, is there any reliable documentation about it?

• How much space do NTFS hardlinks/symlinks occupy?

  - by Felix Dombek

  Well, I guess it must be something proportional to the original filename plus the new filename for symlinks, and only the new filename for hardlinks, but how does this affect the disk space exactly? I just made a folder with about a hundred thousand symbolic links in it, and the folder still reported 0 bytes usage. I may be mistaken, but I even think the free capacity of the drive remained the same. Then I permanently deleted the folder and the sizes still stayed the same. Could I fill up a hard disk just with symlinks? Or does NTFS have limitations in that no more than x symlinks are allowed on one drive/in one folder, so the capacity of the drive cannot be reached?

• Snow Leopard - Dock icons randomly disappear

  - by lostInTransit

  Snow Leopard works great! My mac's really fast after this. But sometimes the dock icons just disappear! I see the blue dot beneath when I click the empty space. So I know the item's there. But there are no icons! This happened for Safari and Downloads. Some people responded on the Apple forums that I should try and remove the dock's plist file. But this just restores the dock to its original settings! I don't want to lose my settings. Anyone else facing this issue with SL? Or is it a problem only I am facing? Thanks

• Clone a Red Hat RAID as part of a disaster recovery plan

  - by Campo

  I am looking for recommendations to clone a Red Hat mirrored raid to a single hard drive located in the same machine. The idea is if the servers hardware ever has an issue we have a similar hardware machine ready to go. All we would have to do is pop in the cloned drive. If the servers RAID ever failed we could just switch to the single drive to maintain uptime and restore the original configuration on the spare server with a backup. This is a restaurant and they are open 7 days a week. We do have time from 12:am to 9:00am to perform the necessary steps for a clone and we talking about under 10 Gigs of information. There is a database on the server. I have looked into Rsync and Clonezilla. But I am just not confident either is capable of completing the task I want. Looking for some suggestions and possibly a step by step if you could be so kind.

• Vista to Vista network visability issue

  - by Sk93

  Hi All, I've got a Vista Business PC and a Vista Business Laptop connected via a virgin media router (Netgear CG2100D) and I cannot get the two machines to see each other correctly over the network. The laptop is connected via wireless, whilst the pc is wired. Both are set to recieve their network settings automatically (DHCP) and both have the windows firewall (the only firewall on either) turned off completely. I can ping each machine fine from one another using the ip addresses, and I can also connect via \. However, connections via \ fail, and I cannot see the machines in the network map. I have tried turning netBIOS to be "always on" on both adapters, but this makes no difference. I've been messing around pretty much for 6 hours now and am getting quite fustrated by this! (my original aim was to get media sharing working, but I've pretty much abandoned that for now). Any ideas?

• Excel: link value once, then prevent change

  - by user1832164

  For some budgeting spreadsheets I'm working on, I'd like to link each month to a value (in this case, a percentage). However, if the original percentage is changed I ONLY want to change values going forward. For example, let's say item one is budgeted at 10%, so each month reflects 10% of the total (which changes every month). If I decide to change that to 12% going forward, I don't want the previously linked values to also change from 10 to 12% (and throw off lots of other numbers). My thought was to have a check box where if I placed an x, the values would be locked to the value at the time of placing the x and no longer change. Is this possible? I know there are options for doing a paste special, but I'm creating this spreadsheet for someone who is not very Excel savvy, so I want it to be as seamless as possible. Many thanks.

• How to prevent Windows from doing this

  - by Murtaza

  I am using Windows 7 Professional 64bit. This is my webcam. It is first time using this webcam in my pc. It's name is A4tech - PK-331F. When I plugged that webcam, windows start installing drivers automatically but unfortunately it installed wrong drivers. The drivers Windows 7 installed are Vimicro USB 2.0 PC Camera (Venus) and these drivers aren't related to this webcam. Now I did some modifications to windows so it isn't installing drivers automatically but whenever I plug that webcam but same name of drivers and doesn't install it. I think because of it, I can't install it's original drivers. I don't want Windows recognize this webcam with this name. How can I prevent Windows from doing this?.

• NAT Policy Inbound Source Problem on SonicWall TZ-210 with Multiple DSL Lines

  - by HK1

  We recently added three more DSL connections to our SonicWall TZ-210. My NAT Policies work fine as long as I leave them set with an inbound interface of X1, which hosts our original DSL connection. However, I'd like to change some of the NAT Policies to use inbound source/interface X2, X3, X4 or Any. In my initial tests, when I change one of the policies to use an inbound interface of X2, that port forward policy does not work at all. Traffic never makes it to the internal destination. What could be the problem?

• How to determine non-movable files in Windows 7?

  - by David

  Is there a way to determine which unmovable files are preventing Shrink Volume from releasing the full potential free space? Background: I have a 90 GB partition with Windows 7 on it, and 60 GB free space. I want to shrink it down to about 40 GB, and use the reclaimed 50 GB for a separate data partition. The Shrink Volume tool in Disk Management is only willing to give me 8 GB back. My understanding is that this is because of immovable files. I've followed the instructions found here, which involved disabling hibernation, pagefile, system restore, kernal dump, making sure all related files were deleted, and defrag'ing. I have successfully followed those same instructions before on this same drive, and partitoned the original 150 GB space into 90 GB and 60 GB, but I'm not so lucky this time.

• I modified my registry and now my laptop doesn't report its battery or power settings

  - by Crouch

  I saved a backup of my registry and then made a change to it. After the change, the Windows 7 battery meter no longer reported how much battery power was left. I also was no longer able to change between Power Profiles in the Control Panel. I tried to restore the original registry but it didn't restore the lost power features. Now I have to keep my laptop plugged in all day because I never know how much power I have left. Anyone know what to do here?

• Open file in local text editor from within an SSH connection

  - by Sam

  I'm not a vim guy. I'd like to be able to open log files in Sublime Text when in an SSH connection from within Terminal. Is there a way I could do this? I'm thinking there must be a command or something that could copy the file over to a temporary directory in OS X and then open it in Sublime Text, and when I save it, it'll copy back to the original location through SSH; similar to how FileZilla does it. I'm on Mac OS X MT. The server I SSH into is running Ubuntu. I'm using Terminal.

• Transparently decompressing data in archive to allow greater compression later

  - by Vi.

  I have, for example, filesystem image which have some compressed files (with weak compression such as gzip), for example, manpages or archives with the same uncompressed content nearby. How to pre-filter the data to "expand" compressed data to plain form (to re-compress it with strong compression) and then post-filter after decompression to restore original "semi-compressed" image? SHA-1 match is advices but not strictly required (but the resulting image must work, e.g. re-compressed files should not grow too much, be decompressible etc.) Like improving compression ratio by reversing weak compression algorithms. Are there programs for this?

• Handout export to word from PowerPoint are too big :(

  - by nickjohn

  EDITED i am using power point lectures. i want to mail merge speaker data into the respective lecture. now thats not possible with ppt as far i know, so i have to convert these lectures to handout by using power point option "publishMS word handouts" and use word mail merger. this is good since it will keep the comments/notes added in slides in handouts aswell. but these exported handouts in word remain actual slides and retain link to original ppt rather than simply get exported as images. so the file size gets verrry big 10mb ppt = 212mb doc=88mb docx Is there any option to convert handouts exported from power point to word as images? i simply cant save them as pngs from powerpoint since that will not include the comments data. Thanks

• How can I redirect URLs using the proxy module in Apache?

  - by LearningIT

  This seems like a super-basic question but I am having a hard time tracking down a straightforward solution, so appreciate any help and patience with me on this: I want to configure my Apache proxy server to redirect certain URLs so that, for example, a web browser HTTP request for www.olddomain.com gets passed to the proxy server which then routes the request to www.newdomain.com which sends a response to the proxy server which then passes it back to the web browser. Seems so simple, yet I don't see how to achieve this on Apache. I know Squid/Squirm offer this functionality so am guessing I am missing something really basic. I know I can use RewriteRule to dynamically modify the URL and pass it to the proxy server, but I effectively want to do the reverse, whereby the proxy server receives the original URL, applies the RewriteRule, and then forwards the HTTP request to the new URL. Hope that makes sense. Thanks in advance for any help.

• Windows share mounted then symlinked on LAMP server. Serves up html, but not images.

  This has really got me befuddled... I've mounted a share, like this: //srv1/UserUploads /mount/UserUploads cifs rw,user,exec,uid=wwwrun,gid=www,username=shareuser,password=sharepw 0 0 I then have a symlink here: WEBSVR:/Web/htdocs/public_html # ls -l useruploads lrwxrwxrwx 1 wwwrun www 18 Dec 7 09:18 useruploads -> /mount/UserUploads Oddly, if I ls inside the mounted area, items appear with a capital S -rwxrwSrwx 1 wwwrun www 4077 Dec 30 14:54 prop9.jpg -rwxrwSrwx 1 wwwrun www 4 Jan 12 15:57 test.html And if I bring up test.html in a browser, it works fine, but if I go to prop9.jpg, chrome gives me this error: This web page is not available. The web page at http://10.1.64.100/useruploads/webteam/help2let/prop6-1.jpg might be temporarily down or it may have moved permanently to a new web address. More information on this error Below is the original error message Error 100 (net::ERR_CONNECTION_CLOSED): Unknown error. Has anyone seen this behaviour where the binary files (images) arent displayed, but html/text is?

• Windows 7 changes desktop icon location when switching from External Monitor to Internal Monitor (laptop)

  - by Gareth Jones

  I have a Windows 7 Laptop, and lately its been acting really weird with my 1080p Monitor. When I get home from school, Ill plug my screen in, and close my laptop lid (which makes the laptop treat the Monitor as the primary and only screen). However it will move my desktop icons! This also happens when I remove / unplug the screen, as shown in the pictures. I hate this, as Im the kinda person who's use to every icon being in a set spot, and so am use to their location. Its a massive hassle to try and move the icons back to their original spot. Anyone have any ideas on how to fix this? Thanks P.S it could be due to the resolution of the screen's being different, but this never happened before in the past Icons on External Moniter (after having moved them manually back into place): Icons after unplugging external monitor (and so using Laptop screen):

• Any FTP clients for Mac OS X that support upload via temporary filename?

  - by Chris582

  Hi, does anybody know of a FTP client (for Mac OS X) that supports uploading to a temporary filename? When overwriting a file on the server, most FTP clients first empty the file and then proceed to upload new content. (Which is how FTP is supposed to work, so everything is fine.) However, what I would like to see is that the FTP client uploads content to a temporary file and once all the content is on the server, replaces original file. This is good feature, because existing file is upgraded almost instantaneously; otherwise, it would be "broken" while the upload is still in progress. On Windows, this feature is available in WinSCP, but I have not found any options for Mac, so far. Any recommendations?

• cat contents of one file into another file

  - by Attila O.

  I have a large (binary) file that has some corruption near the beginning. Then, I have a second, smaller file that I obtain by starting to download the same file again, but interrupt after I have enough bytes to fix the original one. My question is, how do I simply overwrite the beginning of the large file with the contents of the second, smaller file? I could use cat, tail and head, but that would create a copy of the file. There must be a more efficient way. Oh yes, and I'm looking for a linux command-line solution, if that wasn't obvious. I'm using bash, but I have other shells if that helps.

• Home Server Restore

  - by Bryan Avery

  I have had to reinstall Home Server on my server and I would now like to restore it back to the state it was the last moment it stopped. I have the hard drive in a state it was last in, which is a small 250 gb hard disk. I have now installed 1.5tb hard disks, and installed a full licenced copy, as the original copy was a trial version. So I'm in a state where I have a new install, I have one of the old drives plugged in, but I can't transfer the old backups across, how do I do this?
