• iTunes copy just metadata (song and album ratings, playlists) from iPod

  - by Jared Updike

  I have an iPod touch that I synched with my Windows computer (iTunes 9.0 I think) until my harddrive failed and I lost my entire library. I rebuilt the library (songs) from a year old backup (and various other source for songs) but my playlists and ratings are of course a year old. My iPod itself has most of the playlists and ratings I care most about (favorite songs and albums, rated 4 and 5, for example). I have a catch 22 situation where I feel nervous that I haven't backed up my iPod in around 4 months (when my drive failed) so I'd like to back it up as soon as possible... but if I back it up I have to clear all the songs and playlists and copy them back, which I can't really do since I need to rebuild my playlists on my computer first (using the data only available on my iPod!) The question: is there a better way to READ the information off my iPod than doing it manually, song by song and album by album and playlist by playlist (XML, text dump, database, spreadsheet, anything). In other words, mostly I want the information (metadata like ratings and playlists, not songs) copied off the iPod so I can more quickly get my iTunes library ratings and playlists re-built (manually) so I can finally wipe the music and back up my apps, etc. Then I'd like to copy the music back immediately. The part I'd like to avoid is manually navigating everything on my iPod to read through all the playlists and ratings (50 GB, 6,000+ songs) as I re-enter all of that data by hand. I've done a few dozen albums and it's pretty time consuming having to tap around on the iPod. Reading from a spreadsheet (for example, or XML which I could write a script to get into spreadsheet form) would probably help tremendously, plus then I'd have a backup of that information somewhere besides just my iPod.

• SFTP, SCP, Secure Webdav: which is the most suitable ?

  - by Xavier Maillard

  Hi, currently, I am hosting a webdav share setup in order to store files I need anywhere I am. It is available via HTTPS. Things are that I do not need all the HTTP machinery -i.e. my nginx http server is only there for this webdav folder. I am not sure I made the best choice. My requirements on the client side are: secured transfers mountable as a network drive at work with 'near realtime sync' usable for any OS I could use (including my mobile (android)) At first, I chose webdav since it would pass through my work proxy (which refuses all that is not on HTTP/S (port 80 or 443)). Today, I am not satisfied with the setup and even if nginx memory footprint is pretty small, its webdav support is not really "clean" and full. What would you recommend between SFTP, SCP and the current webdav solution ? I think SFTP is the closest solution but I still have to find out how to pass through my proxy ;) SCP seems quite limited as I read about it (only file transfers if I read right). Cheers

• proftpd initial directory for each user

  - by Dels

  After successfully setting up proftpd server, i want to add initial directory for each users, i have 2 user, webadmin that can access all folder and upload that can only access upload folder ... # Added config DefaultRoot ~ RequireValidShell off AuthUserFile /etc/proftpd/passwd # VALID LOGINS <Limit LOGIN> AllowUser webadmin, upload DenyALL </Limit> <Directory /home/webadmin> <Limit ALL> DenyAll </Limit> <Limit DIRS READ WRITE> AllowUser webadmin </Limit> </Directory> <Directory /home/webadmin/upload> <Limit ALL> DenyAll </Limit> <Limit DIRS READ WRITE> AllowUser upload </Limit> </Directory> All set ok, but i need to tell my ftp client initial directory for each user (otherwise it keep fail to retrieve directory), which i think it should be automatically set for each user (no need to type initial directory in ftp client)

• Permanent fix for unicode characters not displaying correctly (as boxes)

  - by Chase

  Please read this entire message before replying. First I know how to fix the issue on a temporary basis. I am looking for a permanent fix. I work with foreign language files a lot. Unfortunately sometimes all the unicode characters in windows explorer, notepad, and other places (as rendered by windows, probably GDI) do not display correctly. That is they display as square blocks, where as they had just been displaying correctly. There are countless methods to temporarily correct the issue. But again, I want a way to permanently resolve the issue. What I have tried: The silly "Hide fonts based on language settings". This setting only applies to what fonts you see in the fonts folder and font dropdowns. It doesn't disable foreign fonts (doesn't work, or if it does, it is temporary). Deleting the font cache file and rebooting (works.. usually, temporary solution). Changing my locale and then back (sometimes works, temporary solution). Rebooting my PC and getting lucky (50-50 chance, temporary solution). Changing my keyboard input/adding foreign keyboard (temporary solution that only seems to work once). Reinstalling windows (temporary solution, sometimes lasts a few months though, I have done this 7 times across 3 computers) What I have not tried: Buying Windows Ultimate and installing the interface packs. This is not a solution. I can't read Japanese/Chinese and I do not want my interface in those languages. What I will not do: Switch to a different brand operating system (unix, linux, mac os x) Switch to an older version of windows (Windows Vista, XP, 2000, etc). So can anyone recommend a permanent fix for the problem?

• How to Set Up an SMTP Submission Server on Linux

  - by Kevin Cox

  I was trying to set up a mail server with no luck. I want it to accept mail from authenticated users only and deliver them. I want the users to be able to connect over the internet. Ideally the mail server wouldn't accept any incoming mail. Essentially I want it to accept messages on a receiving port and transfer them to the intended recipient out port 25. If anyone has some good links and guides that would be awesome. I am quite familiar with linux but have never played around with MTA's and am currently running debian 6. More Specific Problem! Sorry, that was general and postfix is complex. I am having trouble enabling the submission port with encryption and authentication. What Works: Sending mail from the local machine. (sendmail [email protected]). Ports are open. (25 and 587) Connecting to 587 appears to work, I get a "need to starttls" warning and starttls appears to work. But when I try to connect with the next command I get the error below. # openssl s_client -connect localhost:587 -starttls smtp CONNECTED(00000003) depth=0 /CN=localhost.localdomain verify error:num=18:self signed certificate verify return:1 depth=0 /CN=localhost.localdomain verify return:1 --- Certificate chain 0 s:/CN=localhost.localdomain i:/CN=localhost.localdomain --- Server certificate -----BEGIN CERTIFICATE----- MIICvDCCAaQCCQCYHnCzLRUoMTANBgkqhkiG9w0BAQUFADAgMR4wHAYDVQQDExVs b2NhbGhvc3QubG9jYWxkb21haW4wHhcNMTIwMjE3MTMxOTA1WhcNMjIwMjE0MTMx OTA1WjAgMR4wHAYDVQQDExVsb2NhbGhvc3QubG9jYWxkb21haW4wggEiMA0GCSqG SIb3DQEBAQUAA4IBDwAwggEKAoIBAQDEFA/S6VhJihP6OGYrhEtL+SchWxPZGbgb VkgNJ6xK2dhR7hZXKcDtNddL3uf1YYWF76efS5oJPPjLb33NbHBb9imuD8PoynXN isz1oQEbzPE/07VC4srbsNIN92lldbRruDfjDrAbC/H+FBSUA2ImHvzc3xhIjdsb AbHasG1XBm8SkYULVedaD7I7YbnloCx0sTQgCM0Vjx29TXxPrpkcl6usjcQfZHqY ozg8X48Xm7F9CDip35Q+WwfZ6AcEkq9rJUOoZWrLWVcKusuYPCtUb6MdsZEH13IQ rA0+x8fUI3S0fW5xWWG0b4c5IxuM+eXz05DvB7mLyd+2+RwDAx2LAgMBAAEwDQYJ KoZIhvcNAQEFBQADggEBAAj1ib4lX28FhYdWv/RsHoGGFqf933SDipffBPM6Wlr0 jUn7wler7ilP65WVlTxDW+8PhdBmOrLUr0DO470AAS5uUOjdsPgGO+7VE/4/BN+/ naXVDzIcwyaiLbODIdG2s363V7gzibIuKUqOJ7oRLkwtxubt4D0CQN/7GNFY8cL2 in6FrYGDMNY+ve1tqPkukqQnes3DCeEo0+2KMGuwaJRQK3Es9WHotyrjrecPY170 dhDiLz4XaHU7xZwArAhMq/fay87liHvXR860tWq30oSb5DHQf4EloCQK4eJZQtFT B3xUDu7eFuCeXxjm4294YIPoWl5pbrP9vzLYAH+8ufE= -----END CERTIFICATE----- subject=/CN=localhost.localdomain issuer=/CN=localhost.localdomain --- No client certificate CA names sent --- SSL handshake has read 1605 bytes and written 354 bytes --- New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 2048 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : DHE-RSA-AES256-SHA Session-ID: E07926641A5EF22B15EB1D0E03FFF75588AB6464702CF4DC2166FFDAC1CA73E2 Session-ID-ctx: Master-Key: 454E8D5D40380DB3A73336775D6911B3DA289E4A1C9587DDC168EC09C2C3457CB30321E44CAD6AE65A66BAE9F33959A9 Key-Arg : None Start Time: 1349059796 Timeout : 300 (sec) Verify return code: 18 (self signed certificate) --- 250 DSN read:errno=0 If I try to connect from evolution I get the following error: The reported error was "HELO command failed: TCP connection reset by peer".

• Can a website see/know my MAC address even if I use a VPN?

  - by ilhan

  I have searched other results and read many of them but I could not get an enough information. My question is that can a website see my MAC address or can they have an information about that I'm the same person under these conditions: I am using a VPN and I use two IPs: first one is normal one, the second one is the VPN's IP. I use two browsers to hide behind browser fingerprinting. I use both browsers with Incognito Mode. I always use one for normal IP, one for the VPN IP. I do not know that if the website uses cookies or not. But can they collect an enough information to prove that these two identities belong to same person? Is there any other way for them to see that I am the same person? I use different IPs, different browsers and I use both browsers in incognito mode. I even changed one of browsers language to only English. So even if they collect my info from browser, they will see two browsers using different languages. (Addition after edit): So I have changed my IP and browser information and the website can not reach this information anymore to prove that I am the same person using two accounts. Then let's come to the title: Can they see my MAC address? Because I think that it is the last way that they can identify me and my main question is that. I wrote the information above to mention that I changed IPs and I have some precautions to avoid browser fingerprinting (btw my VPN provider already has a service about blocking it). I wrote them because I read similar advices in some related questions but my question is that can they see my MAC address (or anything else that can make me detected) despite all these precautions. And lastly, Is there an extra way to be anonymized that I can do? For example, can my system clock or anything else give an information? Thanks in advance.

• Stronger laptop_mode in Linux

  - by Vi

  Can I have stronger laptop mode in Linux? I want to spin down the hard drive and prevent it to spin up even if something wants to read something not in cache. In general I want to have these modes: Normal Current laptop mode Stronger laptop mode: spin up only when needs to read something uncached (and cache it). No spinups to write something unless really memory pressure (Exception: explicit "sync" command in console). Kernel is allowed to keep processes in D-sleep for 10 seconds for that. Forced laptop mode: do not spin up, period. Keep offending processes in D-sleep unless I turn off this mode. Like there is a bomb instead of hard drive. I also want to have access times tracked (mount -o atime), but I don't want the hard drive to be spinned up only to update them. Is there some settings or kernel patches that can get closer to this? May be I should write special io scheduler for "forced laptop mode"? E.g. echo suspend > /sys/block/sda/queue/scheduler to lock the drive and echo cfq > /ys/block/sda/queue/scheduler to unlock it again?

• Remote Desktop Services Licensing - Does server have to have a RDS role?

  - by transistor1

  I recently set up a "micro" size Windows 2008 Datacenter server on Amazon AWS. My small group needs several concurrent RDS users to be able to access the machine. Without installing the "Remote Desktop Server" role, it allows 2 concurrent connections. I read on MS' website that in order to set up multiple users, we needed to install the RDS role. I did so, but now the application we are trying to share is running much slower than it was before. Prior to the role installation, it was taking about 5 seconds to open; now it is taking a few minutes to open -- without any other users logged on except me. My assumption is that the RDS role may be too much for this micro instance to handle, and currently, changing to another size instance is not an option (it may be possible later if we were to receive enough funding). This leads me to the following questions: 1) Is it a sensible assessment to assume that it is the RDS role is slowing things down, or are there other things that I could look at to speed it up? We are talking about a machine with ~600MB of memory. 2) If I revert back to the pre-RDS role, is there any legitimate way (in terms of purchasing RDS licenses) to get more than 2 concurrent desktops? I did read this, and am not questioning that the answerer is knowlegeable; but someone else may have some other experience. I am also making it clear that we want to do this in a legitimate way. Thanks in advance for any assistance that can be provided! EDIT: if it is helpful in answering the question, the application in question is a Lotus Approach database. Also, I am asking this from a technical perspective: not a legal one. I want to know if it is possible to install valid licenses without the RDS role.

• I want to dual boot Windows 8 on a Macbook Pro that doesn't already have Windows. Do I have to buy Windows twice?

  - by Cam Jackson

  My girlfriend just bought a Macbook Pro, and she wants to to dual boot OSX with Windows. Specifically, she would like to use Windows 8. What I already know is the following: Windows 8 discs are only meant for upgrading from previous versions of Windows Windows 8 discs can be used to do a clean install, but (officially) only if there's already a legit version of Windows on the hard disk I've read somewhere of a disc being used to install Windows 8 on a fresh, out-of-the-box hard drive, and it all went well until the activation phase, where it said that the disc could only be used for upgrades The logical conclusion would be that in my circumstance, the only option is to buy a full (non-upgrade) retail copy of Windows 7, install that using boot camp, then load up Windows 7, insert the Windows 8 upgrade disc and do the 7-8 upgrade. However, I've read quite a few blog posts of people installing Windows 8 using bootcamp (e.g., Ars Technica, which leads me to believe that it might be possible to do so without installing Win7 first. The problem is that I'm not sure if these people were using preview versions, which obviously won't have the license issues down the track. Can anyone provide a definitive answer as to how to put Win8 on a Mac?

• Repairing Windows 7 boot after Ubuntu 10.10 install

  - by Ted

  I've read various threads on this after googling, including one on this site. I had Windows 7 installed on an SSD. I wanted to try Ubuntu so I created a partition for it on the SSD and booted with the live CD to install Ubuntu. Went through the install and somehow Ubuntu carved out another partition on the SSD rather than using the one I had already created. Windows 7 would then not boot but Ubuntu would. I booted with my 7 cd and ran the automatic startup repair, it didn't find any problems. I then ran the bootsect command on the drive with 7. It said it repaired the bootmgr but Windows still would not boot and now Ubuntu won't either. I read somewhere else that it may be due to the partition that 7 was on being changed during the install. I don't care about the Ubuntu installation but I don't want to lose the 7 install, can I delete the ubuntu partition through booting with the 7 cd? Will that do any good? Thank you all! I'm stumped even though I've done startup repairs before, just not after Ubuntu install.

• Input/output error reading USB backup drive on CentOS 6.4

  - by Kev

  I'm suddenly seeing some strange behaviour on our USB backup drive that doesn't make sense to me: (2013-10-21 14:58:23 [root@newdc /]$ cd /mnt/backup/ (2013-10-21 14:59:03 [root@newdc backup]$ ls -la ls: reading directory .: Input/output error total 0 (2013-10-21 14:59:05 [root@newdc backup]$ df -h /mnt/backup Filesystem Size Used Avail Use% Mounted on /dev/sda1 917G 843G 28G 97% /mnt/backup How is it possible for the OS to know how much is in use, but I can't ls any of it as root? Or more to the point, what problem does this indicate? /var/log/messages said this: Oct 21 14:57:54 g5 kernel: EXT4-fs error (device sda1): ext4_journal_start_sb: Detected aborted journal Oct 21 14:57:54 g5 kernel: EXT4-fs (sda1): Remounting filesystem read-only But...read-only is something different than 'throw an io error'... After unmounting to try fsck on it, I had someone on-site look at it, and the drive was not spun up, and had a slow-flashing light, which I believe means it was in a power-suspend mode. So I had them unplug and replug the USB cable, and now (before remounting) it says: fsck from util-linux-ng 2.17.2 e2fsck 1.41.12 (17-May-2010) /dev/sda1: clean, 2805106/61046784 files, 181934167/244182016 blocks I then mount it and now ls works and df reports: Filesystem Size Used Avail Use% Mounted on /dev/sda1 917G 680G 191G 79% /mnt/backup What would cause it to go into such a state without being asked to? Why all the weird behaviour, and now it appears to not be corrupt?

• WIN7 constant BSOD 0x7B on boot, not producing any dump files where to go from here?

  - by prayingpantis

  So my one win 7 pc has been getting a BSOD on boot (roughly a sec after load screen starts) after a power failure. The complete stop code is 0x0000007B (0x80786B58, 0xC0000034,0x00000000,0x00000000) I've searched for quite a while now on the net and it seems like most people gave up after gettting 0x7B and no dump files. What I've tried so far: startup repair - reports it cannot repair computer automatically. BadPatch is reported somewhere in a problem signature contained in the problem details. startup repair with a WIN 7 CD - also fails, I can't recall what the error was, but it was not the same as the error produced with the start up tool shipped with the version of WIN 7 installed on my machine (I think the text had something ACL-ish contained in it) used a boot disk (Hiren's boot iso) - I used it to enable the CrashDump registry key and then after BSOD, read the HDD's dump locations but it was empty. Note, I'm quite sure the registry keys I edited are the correct ones, since the reboot on BSOD option was enabled by default and after I changed the regkey controlling this functionalitty to 0 the BSOD stayed after I booted again. check disk - works and returns no problems, also it seems I'm able to access all my files on the HDD. mem test - works and returns no errors So I'm not sure what else I can do to figure out what is the problem here. I read somewhere that you can use WINDBG to remote debug another PC, but I'm not sure if this is possible since the OS isn't even loaded yet? Also the last driver change I made on the system was installing a video driver, but I had no problems with it and were able to reboot several times until the power outage happened and the BSOD appeared. Any help or guidance for a way to DEBUG this problem would really be appreciated (I'm not really that keen to try a whole bunch of random fixes, I'd rather try and narrow down the problem first).

• Restore a database with LDF file only

  - by Martin

  First of all, i know how stupid it is not to have a any backup. I can't help it, but i have to (try) to solve it. I have a transaction log (LDF) file from a SQL Server 2000 database that contains all transactions since the creation of the database. No truncation has been done. The MDF file is gone. Probably because of some disk failure. There is no backup. Not from the original database and not from the transaction log. I have tried to link the transaction log to a new clean database. But (ofcourse) that failed because SQL Server checks the identity of both files. I have read about software that can read the transaction log. ApexSQL seems to do that. I tried to install the trial version but it gives weird errors when trying to start the program. Anyone knows a solution for me? It may contain third party software, but i prefer a clean SQL Server solution.

• File permissions on web server

  - by plua

  I have just read this useful article on files permissions, and I am about to implement a as-strict-as-possible file permissions policy on our webserver. Our situation: we have a web server accessed through sftp by different users from within our company, and we have the general public accessing Apache - sometimes uploading files through PHP. I distinguish folders and files by their use. So based on this reading, here is my plan: All people who need to upload files will have separate users. But all of those users will belong to two groups: uploaders, and webserver. Apache will belong to the group webserver. Directories Permission: 771 Owner: user:uploaders Explanation: to access files in the folder, everybody needs to have execute permission. Only uploaders will be adding/removing files, so they also get r+w permission. Files within the web-root Permission: 664 Owner: user:uploaders Explanation: they will be uploaded and changed by different users, so both owner and group need to have w+r permissions. Webserver needs to only read files, so r permission only. Upload-directories Permission: 771 Owner: user:webserver Explanation: when files need to be uploaded, Apache needs to be able to write to this directory. But I figure it is safer to change the owner to webroot, thus giving Apache sufficient privileges (and all uploaders also belong to this group and will have the same permissions), while safeguarding from "others" writing to this folder. Uploaded files Permission: 664 Owner: user:webserver Explanation: after uploading Apache might need to delete files, but this is no problem because they have w+r permission of the folder. So no need to make this file any more accessible than r access for group. Being not an expert on file permissions, my question is whether or not this is the best possible policy for our situation? Any suggestions welcome.

• How to add a writable folder to the PHP document root on linux

  - by Ron Whites

  We are building an example bash script for our PHP TestCoverage Tool use on Linux. The development environment is Ubuntu 12.04_1 but we intend to have the linux example work across as many linux versions as possible without modification. The example linux script requires a variable be set to the PHP Document Root path and by default uses a small PHP example source to show the user how our GUI and text report shows the covered and uncovered PHP code areas. The linux script is also intended to be easily alterable by the user to automate the TestCoverage display of users PHP code. The problem we are having with Ubuntu 12.04 (any linux?) is that the PHP Apache2 document root is defined in /etc/apache2/sites-available/default as /var/www and /var/www is defaulted with "drwxr-xr-x" read only access. So in order to add our own folder as /var/www/SDTestCoverage we must change /var/www to "drwxrwxrwx" read-write access. So it seems our script (at least on Ubuntu) will need to ... 1. acquire and save the /var/www permissions then do .. 2. sudo chmod 777 /var/www (to make writable) 3. mkdir -p /var/www/SDTestCoverage (create our folder under the document root) 4. sudo chmod 777 /var/www/SDTestCoverage (make our subfolder writable) 5. and finally restore /var/www permissions Thanks and our Questions are .. 1. Is this the standard way (using Ubuntu) one adds a writable folder under the PHP Document Root? 2. Is this the most general purpose way one adds a writable folder under the PHP Document Root on other versions of Linux?

• Multi-partition USB stick

  - by nightcracker

  In my freelance job as "the dude that fixes your computer" I have an extremely handy tool, a bootable USB stick with Ubuntu LiveCD that allows me to recover and investigate in a known, working environment. Now, I want to reformat this USB stick and reinstall with Casper-RW persistance. I did this a few times before with a FAT-formatted USB stick. It was a horror. The USB drive corrupted constantly, by people accidently removing the USB stick, the computer not properly shutting down, ETC. Now what I want to create a multi-partition USB stick so I can put Ubuntu on a ext partition, but still be able to store some Windows stuff in it, by having a secondary FAT partition. However I read somewhere that Windows will only check the first partition on USB sticks, giving a problem with the first bootable linux partition. Is this possible on some way? EDIT Perhaps it wasn't clear what the problem is. The problem is that I read somewhere that Windows will only recognize the first partition on a USB stick. But I want two partitions, a ext partition and a FAT partition. No issues so far, but in order to be bootable the ext partition must be the first one!

• 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.

• 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.

• Are there tools available for trimming PDF margins?

  - by Charles Duffy

  I have an ebook I'm trying to read in PDF format on a Kindle. Unfortunately, the page headers and footers have some content (page number and copyright info, respectively) preventing the device from scaling the actual text to match its usable area viewing area, thus leaving the actual content too small to read. Various tools are available which will trim off whitespace, but the Kindle already does this; my goal, by contrast, is to remove printed matter outside of a defined bounding box, and the only tool I've found for the purpose is moderately expensive commercial software. I could probably generate a mask in Inkscape; split out the individual pages using pdftk, apply the mask to each page individually (outputting to postscript), and recombine the numerous postscript files into a single PDF. However, this decode/reencode steps would be pretty unfortunate in terms of document size; something able to operate with a bit more finesse would be ideal. I have all major operating systems handy (Windows, several modern Linux distros, a Mac, etc) so solutions don't need to be constrained by platform. Suggestions? (I've reported the issue to the author, who mentioned it to his editor, who hasn't done anything about the issue over the course of more than a month, making the zero-work approach evidently nonproductive).

• Fixing Windows install by connecting its hard drive via USB to a different laptop

  - by Jason

  I tried to upgrade a laptop to SP3, which broke it. I later found out SP3 doesn't work on that 2002 laptop. I can't uninstall SP3, or fix SP2, because the hard drive is now not detected during setup (I've read that's the problem you get). I put the hard drive in a USB drive case and plugged it into my other laptop, and I can read (& write to) the disk okay. (The hard drive won't fit in my other laptop, so I'm using USB.) I need to get that disk back to SP2, or fix whatever files got screwed up causing the disk to not be recognized. I don't want to do a re-install as there are 80GB of files on it I need, and they won't fit on the HD of my other laptop, and also because I no longer have some of the install CDs for software on it. What do I need to do to fix that drive from my other laptop? (I don't want my working laptop (XP SP3) to get screwed with by putting an SP2 disk in the CD drive, or the non-o/s data on the other hard drive screwed with.)

• Corsair SSD appears completely blank and does not retain written data

  - by ebanders

  I have a 180GB Corsair SSD (model# CSSD-F180GB2-BRKT) as the primary drive in a Windows laptop. Recently the machine became unbootable after installing Windows updates. Windows installed updates before the machine shut down and the next time the machine boot up it complained about not being able to find a bootable device. After finding fixmbr unsuccessful at making the machine unbootable, I investigated a little within knoppix. Fdisk revealed an empty partition table. A scan by Testdisk came up empty. And finally 'head -c 1024 | hd' reveals all zeros. Creating a primary partition spanning the whole disk completes successfully, but after a reboot the disk appears empty again. dmesg reveals no read or write errors. smartctl indicates that the drive is healthy- although the SMART attribute values do not appear to be read properly. "Data Page | WARNING: PREVIOUS ATTRIBUTE HAS TWO" and "Threshold Page | INCONSISTENT IDENTITIES IN THE DATA" messages appear within the table of values. I don't have much experience with SSDs. Is this drive dead or something? Can anyone recommend any diagnostic tools that may be suited for diagnosing SSDs?

• Hyper-V snapshots – unable to start VM

  - by ahmedz

  I restarted my Host server after shutting down three guest VMs. After I restarted the machine I tried to start the VMs and got an error stating the the VM failed to start. SERVERNAME failed to start. Attachment 'avhd file path' is read only. Please provide read/write access to the attachment. Error: 'General access denied error' SERVENAME failed to start. (virtual machine ID 17292200-wd22-dd22-d23-dddddd2222) The issue seems to be with the disk space. The VHD file for this VM is 128 GB and there are two AVHD files of 58 and 75 GB. Whereas the total disk space on this drive (E) is 280 GB - the free space is only around 23 GB. I understand that the error is caused by the unavailability of the required disk space. Unfortunately, I cannot increase the disk space on this drive. However I have another drive (D) that has 400 GB of free space. I exported this VM to D drive and then tried to add the copied AVHD files but it gives me a similar error. I am running Windows Server 2008 R2 Datacenter. Any help is appreciated.

• Linux: How do I use Munin in cPanel to monitor MySQL?

  - by Continuation

  I have a cPanel server running CentOS 5.5. I want to use Munin to monitor MySQL. I went to: Main >> cPanel >> Manage Plugins and selected "Install and keep updated" for Munin and clicked "Save". I got the usual bunch of status updates about the install. At the end I got: Going to read '/home/.cpan/sources/modules/02packages.details.txt.gz' Database was generated on Wed, 02 Mar 2011 18:28:33 GMT ..........................................................................DONE Going to read '/home/.cpan/sources/modules/03modlist.data.gz' Out of memory! Callback called exit. Done Done Done Process Complete As you can see I got an "Out of memory!" message. But after that it said "Process Complete". Was Munin installed? When I went back to "Manage Plugins" it Munin has a check that against "Install and keep updated". So is everything alright? And how do I use Munin now? How do i configure it to monitor MySQL? Where can I see the results? Thanks.

• IIS no longer saving session variables

  - by John

  I'm running IIS v7 on a Win7 development machine. I have PHP code that saves session variables and calls them back later. This has been working on this machine for some time. For some reason now, the session variables dissapear immediatly after saving. Code that used to work fine on http://localhost/, suddenly now does not. I have tested different browsers - the vars dissapear regardless of browser. I have tested identical code on different servers. The problem exists only on this development machine. I tried some code that saves a session var, then reads it back and displays it, then shows a link to click on to read it back and display again. What happens is the session var DOES get written and read back and displayed ok. But when you click the link to view it again, it's gone. I don't recall making any changes to IIS. But I did run several malware scanners and clean-up tools. Is anyone aware of any setting in IIS that disallows session vars? Any other throughts?
