• My hard disk does't get recognized

  - by SteveL

  For a few days now I have a problem with my 500GB internal hard disk. I am on Linux Mint 13 but I have the same problem with my Windows installation. When running fdisk -l I can see my hard disk (same on BIOS) but I can't mount it even via the disk utility program. In Windows XP I can see it on the My Computer menu but when I click it, it say's: D:\ is not accessible The file or directory is corrupted and unreadable Is there a way to fix it? Or at least save some of my files and format it? Should I be thinking about the worst-case scenario e.g. my HDD is dead? Edit: The filesystem is NTFS.

• Proxy Server suggestions

  - by Jon Menefee

  Here is the question I have that hopefully is not too general of a question. I have a network with approximately 25 PC's, 3 servers and 25 IP cameras. I have a firewall already on the network and it works fine for what I need, but my client is asking me if there is a way to put a Proxy server on the network to monitor where his employees are going when they surf the Internet. He is not wanting to block them (at least not thru the Proxy server), but he wants to make sure that they arent going to sites that would compromise the networked PCs. I have looked at TMG and it is a little more than what I want. I hesitate adding another firewall to the system because of the security cameras that are presently on the network (IP Cameras). I just want to put a policy in AD that would make certain Users (or Computers) use a Proxy server. Any suggestions on a good proxy server are welcome. Thank you

• Uploading my ITunes music that I saved on a flash drive to ITunes on my new computer then downloading it to my Ipod Touch

  - by Joshua Kricker

  I had an old computer with Windows XP. I transferred all my music, at least I hoped I had to a flash drive. Also, my computer kept giving me error messages that it could no longer sync to my Ipod Touch First Generation. I reformatted my Ipod back to original factory specs on the old computer. I have a new computer with Windows 7. I can't transfer my music from my flash drive to the ITunes Library. I also can't transfer it to my Ipod. I keep getting the message "Songs cannot be added to the Ipod because all of its space has been reserved for data." There's nothing in the Ipod memory. It's clear. What can I do? I want my music back.

• Constant prompts for credentials from one Mac Outlook 2011 client

  - by Top__Hat

  The majority of my Exchange users are all on Windows 7 and have no issues (at least using Outlook...) but a subset of the executives are ardent Mac users running Outlook 2011 for OS X. One of these clients is prompted every 5-10 minutes for credentials. Ticking the checkbox to remember credentials does not fix the situation. Mac version is 10.7.2. I have already removed and rebuilt the EWS virtual directory on my Client Access server. Outlook anywhere is set to NTLM authentication. None of the Microsoft clients are experiencing this issue. What else can I do to make this issue go away?

• What happened to QuickTime Pro for Windows editing features?

  - by Tod

  I used to record screencasts in SnagIt and then edit them in QuickTime Pro on windows with no problem. I haven't done it in a few months and now when I try most of the editing features have gone whack-a-doodle. For instance, if I got to delete a few seconds of video, it actually ends up deleting 20 seconds of video. I have repeated this on various source files including the Sample.mov that comes with QT. Using Edit-Cut looks like it works, but it doesn't actually do anything. Trim still works but that appears to be it. I know at least one other person has confirmed this behaviour. Does anyone have any work arounds. I'm using Windows 7 64 bit. QT Info QT Pro 7.7.1 (1680.42) QuickTime Version 7.6.8 (1675)

• How to force Windows XP to rename a file with a special character?

  - by codeLes

  I have a song that Windows can't play because there is a question mark in the name of the file. "Where Have All the Cowboys Gone?.ogg" // as an example So I try to rename it and Windows complains whether I try it in Explorer or from command prompt. Error I get when trying to copy, rename, or move is: The Filename, directory name, or volume label syntax is incorrect Is there a Windows way to force a rename in this case? Update I'll keep an eye on this question, but after 13 answers and many attempts (aside form 3rd party solutions) it seems that Windows can't do this (or at least my windows can't, no short names). So I'm accepting the answer which was my original solution anyway of using Linux. It would be nice to see Windows handle this somehow, so don't stop just because I've accepted this answer, the question still stands!

• Updating solr on a ColdFusion 9 install?

  - by Jordan Reiter

  I'm thinking about upgrading the solr install included with ColdFusion 9 to the latest Apache release. This raises a few questions: Is there a compelling reason not to upgrade to 3.6 (is it slower than, more cumbersome than, or backwards-incompatible with 1.4) altogether? The solr install included with CF9 is customized. Is there a way to customize it myself, or to at least fool CF into treating it like its predecessor? Will all of my existing indexes work as-is (are?) with the new version? Has anyone out there on ServerFault done the upgrade? I'm especially interested in hearing about unforeseen or unexpected effects from the upgrade.

• solr administration

  - by devrick0

  Does anyone have any notes for an sysadmin supporting solr? I'm looking for anything that might be useful for monitoring & metrics as well as troubleshooting. Some useful links I have found are: /solr/admin/stats.jsp and /solr/admin/analysis.jsp In the logs I have noticed, other than the query, "hits", "status" and "QTime" values. The documentation on what these mean is sparse at least based on the 100+ websites I have checked. QTime appears to be the query time response in milliseconds. Hits is some form of results but I'm not sure exactly what makes that up and I'm not sure about status. Typically I see status come back as "0" but I have seen other numbers such as "5", so my thoughts that it could be either HTTP status codes or a 0 or 1 (good or bad) methodology isn't accurate. All of the documentation I have come across is intended for developers. Any sysadmin-centric documentation would be a big help.

• how to compare files/directories of 2 separate solaris boxes ?

  - by chz

  Hi Friends I have 2 solaris boxes and I need to check certain directories (on local filesystem and mounted nfs) to make sure that they match up on both boxes and to delete or move the other mismatches to elsewhere on the local filesystem. I investigated for unix commands like rsync, and tree but it appears that these commands are not supported on my Solaris boxes. What is the best approach to this problem with the least pain to solve it ? to use rsync, tree and then diff the outputs or find ? I have trouble limiting the find command to certain directories as there are mounted folders that contain too many xml files that I don't care to much in that directory. What's the find command to search multiple directory paths on a single find command. Thanks Sincerely

• Incremental search for un/accented characters

  - by user38983

  Does emacs have an incremental search mode, where searching for a character will search for itself and for any other versions of the character with accent marks, similar to how Google Chrome (at least v27) will do when searching in a page? Alternatively, is there an additional library or piece of elisp code that can put incremental search in such a mode? For example, incremental search for: 'manana', would find 'manana' or 'mañana' 'motley crue', would also find 'Mötley Crüe' (with case-sensitivity off). Even a solution that only covers a subset of these characters would be helpful.

• asymetric encryption of directory

  - by ftiaronsem

  Hello alltogether Currently I am wondering whether it is possible to apply asymetric encryption of a directory in Linux. I would like to achieve the following: Write log files to /var/log/secret Everything written to /var/log/secret is instantly encrypted by a public RSA key (or something similar) The encryption programms I know, i.e. ecryptfs do not support asymetric encryption of files, at least as far as I know. (Correct me if I am wrong). Therefore I am asking here whether you know of any possibility to implement this. Thanks in advance

• Terminal Server Spoolsv.exe error

  - by Voyager

  We are having a terminal server ibm x3650 with 8 gb of RAM. On many occasions, at least once in a day, we get the error "The instruction at "0x7c8199b2" refrenced memory at "0x9ddc2ade". The memory could not be "read". Click OK to terminate the program. Click on CANCEL to debug the program. I have surfed very many sites, microsoft included, but none of them have been able to give conclusive solution for ending this problem. When we press on ok or cancel, then our ERP application (VB-MS SQL) starts to work normally. till such time the message is there, all our reports are hanged (Business Objects reports). We have already installed all the drivers of printers on the TS. Can anyone help?

• Getting back the old alt-tab windows switching behavior in Windows 7?

  - by Carlos A. Ibarra

  When you run more than 6 applications on Windows 7 and you press alt-TAB, icons representing the first 6 applications and the desktop appear on the first row of the grid and you can cycle with alt-TAB-TAB... through the 6 most recently used windows the usual way, but the 7th and other less recently used windows don't follow the same rules. Instead they get grouped together according to their application but disregarding whether they were recently used or not. This new behavior is mentioned here. I am very used to the old way of cycling and the new system is driving me crazy. I tend to have 20 or so windows open at one time and I frequently need to alt-tab to the 7th or 8th window on the stack but it doesn't work the same anymore. Does anyone know how to put back the old behavior, so that alt-tab-tab-tab... goes through the whole list in most-recent to least-recent order?

• Add users in Windows machine without AD

  - by guillem

  I have several development machines where I am the administrator. We are using AD in my organization but is maintained by and offshore IT group any request takes a long time. We are currently granting access to developers on development machines manually so it's a bit annoying to maintain although at least it's fast. We have also a lot of external consultants that need to use those machines for some time. Is there any tool or method to maintain a set of users synced on those machines without the need add them to an AD group?

• Seeing double-cursor in 'recursive RDP'

  - by John

  I'm using a Virtual PC VM on my PC to connect to a remote PC using RDP over a VPN. It works just fine except that in the RDP session, I often see a double mouse cursor... I get a standard mouse-arrow and the context-specific cursor such as a caret or hourglass. It's not a big problem but rather annoying and I wondered if there's any way to fix it, or at least understand where it comes from? Is it because I'm effectively running one RDP session from inside another? My host PC runs W7, my local VM runs XP, and the remote PC access using RDP is W7. Thankyou for any help.

• How does the performance of pure Nginx compare to cpNginx?

  - by jb510

  There is now a Cpanel plugin to fairly easily setup Nginx as a reverse proxy on a Cpanel/Apache server. I've been simultaneously interested in setting up my first unmanaged VPS and my first Nginx server and as a masochist figured why not combine the two. I'm wondering however if it's worth setting up a pure Nginx server vs trying out cpNginx on Apache? My goal is solely to host WordPress sites and while what I've read raves about Nginx's is exceptional ability serving static at least as a reverse proxy, I am unclear if there is substantial benefit to running a pure nginx with eAccelorator over cpNginx on Apache for dynamic sites? Regardless I'll be running W3TC on all sites to cache content, but am still interested if there are big CPU reductions running PHP scripts under pure Nginx over cpNginx?

• Linux periodically "losing" ability to connect to server via SSH?

  - by gct

  I know this isn't exactly a programming question, but it popped up in my use of git for programming projects at least. I've got a web server that I use to host my git repos on, but my ubuntu box seems to "lose" the ability to connect to it via SSH. I'll get a "connection refused" error when I try to ssh or use git. Rebooting my local machine will fix the problem, but only temporarily. I can still connect to the web interface just fine, and the problem manifests with other servers as well. I've been working around it by pulling my changes over to my laptop and pushing from there, but that's sub-optimal as you can imagine. Has anyone seen something like this? I'd be tempted to say it's some kind of IP caching problem, but I can't connect even using the IP address of the server directly... Running Ubuntu 9.04

• Site's performance slows over time until Apache is restarted

  - by udbhav

  I'm running a Django app w/ Nginx and Apache. All our static media is stored on S3, and basically it takes a while for the app to check if thumbnails have been created every time a page is loaded. To alleviate this problem, I'm caching the output of the templates w/ memcached. Over the course of an hour or two, the site's speed goes down significantly, until I restart apache, and then all is good for a little while. I have very little sysadmin experience, and was hoping somebody could at least point me in the right direction.

• Can't rename folders in Window 7/32bit after anti-virus change

  - by Tasos

  I recently started having the common, as I realized, problem of not being able to rename folders in Windows 7 (32 bit). I don't understand why it happened after almost a year of ideal use of Windows 7. I haven't removed the libraries nor can I think of anything else that could potentially cause this, at least as far as I know. The only thing I did recently was to change my anti-virus program from the freeware version of Avira to the freeware anti-virus Microsoft Security Essentials. Any idea on what the problem is and how to fix this?

• set chars to uppercase between parenthesis

  - by emzap79

  let's assume in vim I have following lines: all what (strong) people have to do is pushing (heavy) weights over (and over) again in order to gain muscles and I need to convert words inside parenthesis to uppercase, what is the most convenient way to do so? How do I tell vim it needs to select everything to the first (!) closing parenthesis? So far I came up with :%s/\s(.*)\s/\U&/g unfortunately this will uppercase everything between 'strong' and 'heavy' which is not what I want. Any chance to tell vim it should select the chars to the next closing bracket only? (sorry for the silly example, couldn't think of something more sophisticated... or at least vim related... huh)

• First Linux - Ubuntu - should I change anything right away?

  - by Cyrcle

  I'm going to be getting a new system next week. I'm finally going to take the leap and run Linux as the native OS on it. Seems like a standard install of Ubuntu is the way to go for a newbie. I'm planning on 10.04 LTS. Is there anything that I should change right away that will cause me problems down the road? I'll be using this system for web development, mainly programming PHP. I'll be using my old laptop for testing with IE and Safari, at least until I either use Wine or VirtualBox to run them on the new machine. I think I'm going to force myself to learn Vim while I'm at it.

• How can I tell how many bits my ssh key is?

  - by yairchu

  I already created an ssh key for myself sometime in the past. I don't remember "how many bits" it is. How can I tell? I'm wondering because I'm using hosting at nearlyfreespeech.net and their faq says: Can I configure my ssh connection to use a public key? ... we will not install keys that have a length less than 1536 bits ... We prefer that you use a key at least 2048 bits in length, and if you are generating a new key, the recommended length is 4096 bits.

• All HTTPS, or is it OK to accept HTTP and redirect (secure vs. user friendly)

  - by tharrison

  Our site currently redirects requests sent to http://example.com to https://example.com -- everything beyond this is served over SSL. For now, the redirect is done with an Apache rewrite rule. Our site is dealing with money, however, so security is pretty important. Does allowing HTTP in this way pose any greater security risk than just not opening or listening on port 80? Ideally, it's a little more user-friendly to redirect. (I am aware that SSL is only one of a large set of security considerations, so please make the generous assumption that we have done at least a "very good" job of covering various security bases.)

• Is Joerg Schilling’s “sdd” a full replacement for “dd”

  - by fishtoprecords

  I was directed to post here, I started on Stackoverflow.... I'm trying to use 'sdd' on my Debian system, and can't get one set of options to work. They do work in 'dd' so I am wondering if I am specifying them incorrectly, or if sdd didn't implement them, or something else. What I want to do is sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 conv=sync,noerror if I leave out the "conv=..." option, it works, or at least starts copying data. sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 Can you shed a bit of light?

• In OpenOffice Spreadsheet, how can I set the default Date format?

  - by Joe Casadonte

  I'm using OO 3.1.1 on Ubuntu 9.10 (in case that matters to the answer). I like my dates to appear as YYYY-MM-DD. I can't think of a time when I want to see a date in any other format, so I'm constantly changing how dates look. That's manageable, though annoying. What's gotten me to the point of posting is that when I edit a cell with a date value, I have to edit it in the format MM/DD/YYYY, which is really, really annoying, as I'm usually mucking with the day (or possibly the month), and very seldom the year. So there's lots of cursor or mouse use, wasting my time. So is there a way that I can change how dates are edited, or at least the default display format? Thanks!
