• Viruses on external hard drive -- how to clean files?

  - by Jade

  Last year my Dell laptop caught some pretty nasty viruses; I saved all my important stuff on an external hard drive. In an unrelated turn of events, I replaced my Dell with a Mac and have been able to retrieve data from the hard drive without trouble. The problem is, I'm sure the hard drive has a few lingering viruses and I really don't want to infect any more PCs with it. I was planning to reformat it anyway, but I'd like to be able to save my files. Would transferring those files to my Mac and then scanning them for Windows viruses before throwing them back onto the newly reformatted hard drive be enough?

• Mount a remote Linux hard drive as another Windows 7 partition during boot?

  - by zhuanyi

  I would like to mount a hard drive on a remote computer (running on CentOS 6) as a Windows drive so that I can install programs to that drive. The primary hard drive for my Windows machine (which is at home) is pretty small, I have a Linux server sitting in a remote data center with a much larger hard drive and allow me to install more stuff. I know most of you are going to say Samba, unfortunately the biggest problem for me in this case is that I can not mount Samba as a network share unless I start OpenVPN or SSH tunneling first, which is not good for my case because I will install some startup programs to the remote drive as well. Therefore, the remote drive has to be ready and work just like another drive BEFORE any of the startup programs start to load. Is that possible? My home PC has Windows 7 Professional 32 bit installed and the remote server is a Xen virtual server running on CentOS 6. I have admin/root permissions for both. Thanks a lot!

• Installing WiFi in a church for internet access

  - by Dave Griffiths

  Hi, a colleague at work asked this question: My local church want to get WiFi enabled in the whole of their offices and main church building. The offices and main building are in the same overall structure and so the signal does not need to travel outside to any other buildings outside this main structure. Where would I start on such a project and what kind of repeaters are needed (and how are they set up) given that some of the walls are pretty thick. Do you still have one ADSL line coming in to router or are there some options of having two lines coming in so that they isn't a single point of failure. Am looking at fibre for the broadband for increased speed. Any starting pointers appreciated.

• Vagrant sahara plugin - multiple snapshots

  - by BazZy

  How I can make more than one snapshot when in sahara sandbox mode? Or, can I see list of all commits I've ever made and rollback to any? Why do I need all this? I just want to setup initial VM. After that I want to compile number of packages from sources, and this takes pretty long time. So right now I thinking of this order: Setup initial ubuntu 12.04 vagrant box Snapshot this state Compile sources, install system wide rbenv (it make compilation also) Snapshot second state Start all my infrastructure experiments Rollback to any of my previous states or commit third state

• I try to access a NFS mount via FTP. It works but the FTP Dir listing is very slow

  - by W0bble

  I mount an NFS using this command: mount -o rsize=8192,wsize=8192,timeo=14,intr serverip:/directory /mnt/directory However the mount appears on the client as expected a cmd like "ls -a" work pretty fast on the nfs mount. But when I try to list the mounted directory via FTP it gets very very slow ( 1.250 bytes in 160,39s (0,01KB/s) ). But surprisingly downloading files via FTP from nfs work with normal speeds. I tested several values for rsize and wsize parameter with no success. Both client and server are running Debian squeeze and NFSv4

• What are the recognized ways to increase the size of the RAID array online/offline?

  - by user149509

  Is it possible, in theory, increase the size of the RAID-array of any level just by adding new drive(s)? Variant like "backup whole data - delete old array - add/replace disks - create new array - restore data" is obvious so what are the other options? Does it depend on the RAID-level only or on the implementation of RAID-controller only, or on both? Adding new disks to a striped array necessarily leads to a rebuilding of the array with the redistribution of the strips to the new drives? What steps should be done to increase size of RAID-array in online/offline scenarios? Especially interesting RAID-5 and RAID-10. I would like to see the big picture.

• Windows Command queue?

  - by Stefano

  i'm thinking if does exist some kind of software that can put in a queue a bunch of windows commands... for example i can say to first copy some file somewhere, then rename those, then delete the old files, then edit one of them etc.... without waiting the effective execution of any of those passages.... this could be useful when copying big files that take a lot and i don't want to sit in front of the computer keeping the eyes on the progress bar... does exist anything like this?

• Why is my library/Documents shortcut showing all files from all subfolders in one flat list?

  - by korro

  I am using Windows Explorer on Windows 7. In My Documents there's a folder 02 KOOP. If I go there using the adress bar: D:\users\username\My Documents\02 KOOP I get a view of my subfolders and some files: However when I use the Documents shortcut under Libraries, and then go to the 02 KOOP folder, all files that are located in all subfolders are listed in one big list. When you view the file properties, the actual location is shown: This is the only subfolder of My Documents that has this behaviour. Did I accidentally change some setting, or is something wrong? Is this some setting I accidentally changed?

• Filter tagged threads in Thunderbird

  - by Let_Me_Be

  I have a big issue with Thunderbird, I need to process a lot of emails coming from request tracking system. Since only few of those apply to me personally, I tag these threads with appropriate tags. The issue now is that I would like to filter out threads, that do apply to me and those that I haven't tagged yet. I'm unable to do this, because new emails keep arriving into the already existing threads, and of course, these new emails don't get the tags. Basically I would need some sort of filtering rule, that would apply not to a specific message, but the master message in the thread. Is there some possibility to create such filters, or is there some other facility, that would allow me to do the same? Tags are great, since they are actually saved into the messages and correctly sync across multiple machines when using IMAP.

• Page loading hangs and never times out (Apache)

  - by Lucas -luky- N.

  I have set up Apache2 on a guest Ubuntu 10.04 OS (virtualbox). I have created a "big" HTML file (4MB) with only plain text and when I access a page through my local IP address such as http://192.168.0.100 it successfully loads the entire page. However, when I try to access it through my public IP address the browser loads part of the page and then hangs forever on "loading". I can load a simple webpage though. I'm not sure whether it's an issue with my Apache configuration, Virtualbox, Router or Modem. Any clues? Tried enabling Debug and mod_status but didn't find any useful information.

• How can I get Google to re-point its search entries to new domain?

  - by poolski

  My main .com domain registration lapsed and when I went to re-register it, I found that a domain reseller service squatted it and I've lost access to it. As I wasn't terribly keen on spending money on funding scammers and the like, I registered a .co.uk domain under the same name. Is there any way of getting Google to re-point all its indexed links to the new domain? It's been indexing my blog for a couple years now and while it's not too big a deal, I'd like to not have to start all over again. Also, searching for my site results in an old entry which is currently pointing at a "Apply for a Tax Break NOW!!!" page.

• VBA: Parse preceding numbers from string

  - by buttonsrtoys

  I need to parse into two substrings a string that always starts with numeric text followed by alphnumeric text. The strings can vary a bit, but not too much. Below are examples of incoming format and the strings I need: "00 10 50 Information to Bidders" ==> "00 10 50", "Information to Bidders" "001050 Information to Bidders" ==> "001050", "Information to Bidders" "00 10 50 - Information to Bidders" ==> "00 10 50", "Information to Bidders" "001050 -- Information to Bidders" ==> "001050", "Information to Bidders" I was hoping it would only be a half dozen lines of VBA, but my code is turning into a loop where I'm testing every character in the string to see where the changeover from numeric-only to non-numeric, then parsing the string based on the changeover location. Not a big deal, but messier than I was hoping for. Are there VBA functions that would eliminate the need to iterate through each string character?

• Is it possible in Gnumeric to paste-special only background colors w/o overwriting foregroudn colors, boldness, etc?

  - by darenw

  I've written a huge complex spreadsheet in Gnumeric, with areas of different background and foreground colors, text and numbers in bold or various colors to indicate meanings. Certain cells ise a diagonal pattern combining the surrounding background color with black - this warns me not to alter those cells when I haven't had my morning coffee. Big problem is changing just the background color of an area - to do so wipes out boldness, foreground colors and the diagonal-pattern cells. I use "Paste Special" and choose Format to copy-paste colors from one area to another, or make the pattern of bold/normal of several rows match one that's done right. What I'd like "paste special - just the background colors (but preserve patterns and 2nd colors of backgrounds)" and "paste special - just the text style/fonts" but I've never encountered any such thing. Are the effects I want possible?

• Fusion 3, Windows 7, frequent blue screens

  - by kenny6127

  Is anyone else seeing this problem? A solution would be great (hey, it's Windows, it's gonna blue screen, just gotta deal with it), but it's also nice to know if it's something specific to my configuration, or if a lot of folks are having the same issue. Here's the details: * MacBook Pro 15" unibody, 4 GB, 2.4 GHz, 10.5.8 * Fusion 3.0.1 * Windows 7 Pro, 32-bit (clean install, not migrated from Boot Camp or anything) Blue screens happen nearly every time the MBP cover is closed for a short period of time (< 3 minutes). If the cover is closed for a half hour or longer, the VM is fine. I'm guessing it might be related to sleep, but that's hard to tell, and the Windows crash dump logs are pretty useless. Thanks!

• Display issues on new OpenSUSE install

  - by user1319182

  I installed OpenSUSE 13.1 on my newly built PC, but the display is just horrible : the edges of the screen are missing. For example, I can't see all the top part, I can barely read the date and I see "ctivities" instead of "Activities". However, when I take a screenshot everything seems to be fine (the cursor doesn't appear though) the characters are sometimes too big and sometimes too small the cursor is huge and many other strange things. I took a few pictures I'm using an Intel integrated GPU (HD4400) and made all the possible updates with YaST. Any idea how I can fix this? Thanks

• Can you remap "C:\Program Files" like you can with "My Documents"?

  - by Danny

  I'm not sure if this is possible, but I'm hoping you guys will know one way or the other! I'm going to be reinstalling windows xp, and the primary master IDE is a smaller 10 gig drive. I'm pretty sure that if I tried to install all my programs back onto the C:\ drive that they'd not all fit. Is it possible to get my Program Files directory to point to a partition on one of my larger drives, so I don't end up with some of my programs on C:\ and others on D:\, E:\, etc?

• Is it safe to remove Per user queued Windows Error Reporting?

  - by Rewinder

  I was cleaning up my laptop hard-disk, running Windows 7, and as part of the process I ran the Disk Cleanup utility. To my surprise I saw 2 items in the list that were quite large (both ~300MB). Per user queued Windows Error Reporting System queued Windows Error Reporting I guess I had never noticed these, because they were never that big. So, what are these items? Any particular reason why they became so large all of a sudden? And finally, is it safe to remove them?

• Zentyal Server : Setting up secure VPN Client

  - by JustShrey

  I have officially exhausted pretty much all my google-fu trying to set this up so I'm asking my question here. For the record, I am a mid level rookie who has played around with servers in his spare time but have never worked with Zentyal Server. Now, I have been able to set up the server as a gateway, with one Network card being external and the other facing the internal Network. The Internal network computers are able to access the internet without any issues. What I need to do is to setup a open-vpn client on the central server so that all Internet data goes though the secure VPN session. As far as I can see, I can't set up the vpn session through the web admin page. Could somebody point me in the right direction? How would I go about doing this? Regards Shreyas

• Highlight column when a row is clicked, depending on condition

  - by Fredrik

  We have a large matrix with lists of servers on the rows and persons as columns. Then we mark the column/row with an X if the person has access to the server. Pretty basic. But as the matrix grows, it becomes more difficult to quickly find the right person with access. So I'd like some way to make it easier to use In the example above I have clicked on the row "Resource B" and would like all the columns where there is an "X" (User 1, User 2) to be highlighted somehow. Then if I click the row for "Resource C", "User 1" should be highlighted.

• Sun Directory Server 5.2 performance

  - by tmow

  Hi all, I'm using logconv.pl (provided by Sun), to measure performance on my server. These two metrics results, are worrying me a bit: Binds: 192164 Unbinds: 111569 In fact the difference between the two it's quite big, how can I determine which are the unbound requests? As stated by Lodovic: Many applications just close the connections without sending an Unbind request. This simply can explain the difference. But the logconv.pl doesn't show details about the unbound requests, do you know any other tools or can you suggest some queries or whatever that can help me find out the root cause? Do you think anyway that the performances may improve fixing the issue?

• Change filtering method used by Firefox when zooming

  - by peak

  I often zoom in a step or two when reading long texts in Firefox, but when I do so the images become super blurry. It's not really a big deal but when reading text on images (mathematical equations mostly), it's a bit distracting. It seems as if they are scaled using only bilinear interpolation. If I scale an image the same amount in for example Paint.NET or Photoshop the result is much better. Is there any way to change the filtering method used by Firefox to bicubic or another better method? I am Using Firefox 3.5 on Windows BTW.

• ASUS N550 laptop not charging on ubuntu after updating kernel

  - by OBY Trance

  I'm using Ubuntu 13.10 on a pretty new ASUS N550jv laptop. When I was using kernel linux-image-3.11.0-11 everything was quite well (kinda..), however, when I updated the kernel using the automatic update, the kernels which were released afterwards (12+) were faulty on my machine, and caused the battery not to be charged and only stay at their current charging level (even when the machine was off!) The only fix I had was to roll-back to the '..11' version (on boot screen - advanced options), and hard-reboot (AC cord disconnected and reconnected) but now version 14 was released and "pushed away" the good old version 11. How can I fix that?? Please help me...

• Help recovering lost text from a refreshed Chrome webpage (it was in the clipboard as well)? [closed]

  - by tobeannounced

  Possible Duplicate: Chrome: where is the location to save browse temporary files Ok, so here's what happened - and yes, it was pretty stupid by me: I wrote up and submitted a post on Stack Overflow It was not suited to be placed on Stack Overflow as someone pointed out to me, so I deleted the post (this was a few hours ago) I copied the text into a new question page on Super User, but didn't submit it yet I accidentally just refreshed the webpage that had the text, and the question has now been deleted from Stack Overflow I have Lazarus installed, however the Chrome version doesn't have many features and the text was not recoverable from there. I do not have a clipboard manager, but the text was copied to my clipboard - so is there any way to get this back (Windows 7)? Although the post on Stack Overflow was deleted, I suppose it would have existed in my cache - could I recover it from there? Would the post on Stack Overflow exist in an rss feed anywhere? Many thanks, and I hope I can find this - and I am sure that the solution will prove valuable for me (and others) in the not too distant future once again.

• Rejecting new HTTP requests when server reaches a certain throughput

  - by user56221

  I have a requirement to run an HTTP server that rejects new HTTP requests (with a 503, or similar) when the global transfer rate of current HTTP responses exceeds a certain level. For example, if the web server is transferring at 98Mbps, and a new HTTP request arrives, we would want to reject this (as we couldn't guarantee a good speed). I've had a look at mod_cband for Apache, limit_req for nginx, and lighttpd's rate limiting features, but none of them seem to handle my (rather contrived, granted) use case. I should add that I'm open to using pretty much any web server, and am open to implementing this in iptables rules if someone can craft such a rule! (Refusing the TCP connection is fine, it doesn't have to respond with an HTTP 503). Any suggestions?

• Cloned Windows 7 to new HDD and want to change the drive letter to C

  - by Hoppe

  I used Clonezilla to clone my existing hard drive to a new one I bought. I then changed the BIOS to set the new drive as the first in the boot sequence. I'm pretty sure that I'm still running Windows 7 on the old drive. My old drive is marked as C. Now that I don't have a disk drive any more, how I do I swap the drive letter from J: to C:? I tried to change it in the disk management section of "Manage", but it reports: "the parameter is incorrect".
