• Can't log in after restoring from Time Machine

  - by Jay Conrod

  My friend uses a Macbook Pro with Snow Leopard 10.6.2. She uses both FileVault and Time Machine to preserve her data. Recently, she suffered a hard disk failure. After restoring from Time Machine using the Snow Leopard install disk, she gets the following error when logging in: You are unable to log in to the FileVault user account at this time. Logging into the account failed because an error occurred. When examining the file system through Terminal, I noticed her home directory is not present: there is no /Users/username directory, or the FileVault .sparsebundle file that's supposed to be there. When using Time Machine.app on /Users, it appears as if her home directory as never there. Additionally, I did a search on the backup disk with the following command: sudo find /Volumes/backup -name '*.sparsebundle' No results. She told me that after working with some large data files, Time Machine would come on, and it would sound like it was transferring a lot of data to the hard disk. Time Machine must have been doing something, right? How can we recover her files? Are they still there?

• 24TB RAID 6 configuration

  - by Phil

  I am in charge of a new website in a niche industry that stores lots of data (10+ TB per client, growing to 2 or 3 clients soon). We are considering ordering about $5000 worth of 3TB drives (10 in a RAID 6 configuration and 10 for backup), which will give us approximately 24 TB of production storage. The data will be written once and remain unmodified for the lifetime of the website, so we only need to do a backup one time. I understand basic RAID theory, however I am not experienced with it. My question is, does this sound like a good configuration? What potential problems could this setup cause? Also, what is the best way to do a one-time backup? Have two RAID 6 arrays, one for offsite backup and one for production? Or should I backup the RAID 6 production array to a JBOD? EDIT: The data server is running Windows 2008 Server x64. EDIT 2: To reduce rebuild time, what would you think about using two RAID 5's instead of one RAID 6?

• iBook G4 has black screen on boot

  - by Jonathan Patt

  I have an old iBook G4 (A1054, 1.2 GHz) which has issues when it loses power or is shut off. If the battery drains—which happens quickly, as its remaining capacity is very low—it enters some sort of weird mode where it's not really awake (the screen is black, can't do anything) but it has no pulsing light indicating it's asleep either. The only way to exit this mode is to hold down the power button for ten seconds until it shuts off, and attempt rebooting it. Almost always, however, it makes the sound of the optical drive starting up, and then doesn't continue past that point. The screen doesn't come on, and things like resetting PRAM don't work. Occasionally a fan comes on loudly for a second or two. This sometimes seems to correspond with my pressing down on the rear-right casing, above the power jack. In the past, shutting it off, disconnecting it from power, removing the battery and waiting for 30 minutes would do the trick, but this time I have done that several times, letting it sit for up to several hours before retrying, to no avail. Any ideas?

• Rebinding Keys on a Dell Keyboard

  - by Maarx

  I have a Dell Multimedia Keyboard, similar to this one: It has many non-standard keys, like the small circular ones across the top, and the "Multimedia" keys above INSERT/HOME/PAGE_UP. They can be rebound through simple registry entries. Some sample ones are included below: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\15] "ShellExecute"="C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe http://mail.google.com/mail/#inbox" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\16] "Association"=".cda" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\17] "ShellExecute"="C:\\Windows\\System32\\SnippingTool.exe" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18] "ShellExecute"="calc.exe" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\7] "Association"="http" I've rebound the "MAIL" key to, instead of booting Outlook, to booting Firefox directed at my G-Mail account. I've rebound the button that would normally open "MY COMPUTER" to instead boot the Windows 7 "Snipping Tool", something I find very useful. Now, I'm looking to do some other things that I don't already know how to do. Note that answering this question doesn't necessarily require any knowledge about the keyboard or rebinding the keys: I can add, for any given key, a "ShellExecute" entry, and it will simply execute the following command as if it was typed at a Command Prompt. (I'm aware I dumbed that down rather significantly, but bear with me. I'm not really a Windows guy myself.) I use the volume knob for it's intended purpose, to change volume. I would like to change, however, a different key, to "reset" the Windows volume level back to exactly 50%, or, as it refers to it, "50", on it's 0-100 scale. I'm looking for the "program" (what I would type at a command prompt? these are still just Sys32 programs in the PATH, aren't they?) that, I imagine, would take arguments, to change Sound/Volume settings under Windows 7. Perhaps, for clarification, something that might take the form "C: SetVolume -slevel 50" or something.

• Vista failing to load after apparently being repaired

  - by Joomaz

  Hi, I apologise if I'm a litre vague and can give more info if needed. My vista machine has been working fine until today when I tried booting it. Vista loads showing the loading bar then goes to a black screen with the cursor on which you can move. It then remains like this for several minutes, during this time the computer doesn't sound like it's doing much, it is relatively quiet. Finally the welcome screen appears. It stays on this for several minutes again and the computer reboots. This keeps happening and the machine fails to load in safe mode - the same happens. I booted the pc with the vista disk in and ran repair your computer and used the system repair. It took about 20 minutes saying it was repairing damaged giles. I booted the pc again and the same happened. I loaded the pc with yeh vista disk again and chose repair my computer again. System repair seemed to run automatically this time and agian it did the same. I rebooted and the problem persisted. I then tried system restore to a few days ago. After half a hour as it finished it said it failed due to a portion being corrupt. I am really not sure what to do now. Any advice appreciated!

• vagrant and puppet security for ssl certificates

  - by Sirex

  I'm pretty new to vagrant, would someone who knows more about it (and puppet) be able to explain how vagrant deals with the ssl certs needed when making vagrant testing machines that are processing the same node definition as the real production machines ? I run puppet in master / client mode, and I wish to spin up a vagrant version of my puppet production nodes, primarily to test new puppet code against. If my production machine is, say, sql.domain.com I spin up a vagrant machine of, say, sql.vagrant.domain.com. In the vagrant file I then use the puppet_server provisioner, and give a puppet.puppet_node entry of “sql.domain.com” to it gets the same puppet node definition. On the puppet server I use a regex of something like /*.sql.domain.com/ on that node entry so that both the vagrant machine and the real one get that node entry on the puppet server. Finally, I enable auto-signing for *.vagrant.domain.com in puppet's autosign.conf, so the vagrant machine gets signed. So far, so good... However: If one machine on my network gets rooted, say, unimportant.domain.com, what's to stop the attacker changing the hostname on that machine to sql.vagrant.domain.com, deleting the old puppet ssl cert off of it and then re-run puppet with a given node name of sql.domain.com ? The new ssl cert would be autosigned by puppet, match the node name regex, and then this hacked node would get all the juicy information intended for the sql machine ?! One solution I can think of is to avoid autosigning, and put the known puppet ssl cert for the real production machine into the vagrant shared directory, and then have a vagrant ssh job move it into place. The downside of this is I end up with all my ssl certs for each production machine sitting in one git repo (my vagrant repo) and thereby on each developer's machine – which may or may not be an issue, but it dosen't sound like the right way of doing this. tl;dr: How do other people deal with vagrant & puppet ssl certificates for development or testing clones of production machines ?

• cPanel web server redundancy advice?

  - by crgnz

  At present I operate a (reasonably low volume) web-hosting service with a Centos 5.3 server running cPanel/WHM. I would like to implement a level of redundancy such that in the event of server failure, I can restore service with a minimum of effort in less than 60 minutes. I also want to setup a secondary DNS that cPanel will replicate with. My current idea is to kill two birds with one stone by: My current server is called "www1" Purchase an identical server (HP DL360 G4) with mirrored disks. Call this server "www2" Install Centos 5.4 (or perhaps I should install 5.3 to be identical with www1) Install cPanel/WHM on this server and fully license it Setup www1 and www2 cPanel to replicate DNS with each other Setup a nightly replication script that does the following: a) rsync's the /home directory from www1 to www2 b) dumps all MySQL databases on www1 and copies them to a temp folder (with root access only) on www2 c) triggers a script to run on www2 that restores the MySQL dumps Thus each night a fully working copy of all the websites and MySQL databases is copied to www2. I do not have enough knowledge of MySQL replication to understand if it works safely and transparently with cPanel. Thus I propose the mysql dump/copy/restore due to not knowing any better! In the event that www1 dies a horrible death, I envisage that I could login to www2, change the IP addresses to those that www1 had, and presto, the websites are available again. The advantage of this idea is that it is fairly simple and "low tech" and thus does not require an expert sysadmin to setup and monitor (I am NOT an expert sysadmin) The disadvantage of this idea is that up to a full days worth of data changes would be lost. I think this would be acceptable to the sorts of customers I host at the moment. The other disadvantage would be having to pay for a full cPanel license, but I am comfortable with that cost, so for now all I want to discuss are technical considerations. Is this a sound scheme?

• A fatal exception 0E occured at 0028:xxxxxx in VxD IOS(01)

  - by winlin

  I get a blue screen of death in my windows 98 machine every time I boot it. I can't reach to my desktop. The error is like this: A fatal exception 0E occured at 0028:C003CC2F in VxD IOS(01) + 0000156B This was called from 0028:C0082E60 in VxD VKD(01) + 000001D0 I have to then give it a three finger salute to restart the system.

• Two audio streams - headphones and speakers

  - by Sylvester

  What I want (this is probably hard for most to answer, as this is a very unique setup) is to have two different streams (this means audio splitter is not an option, as it will still only be one stream) of audio - one through the headphones and one through the main speakers. I can do the audio rerouting using virtual audio cables, however the problem is this: i cannot get both headphones AND speakers to play even just one stream, let alone two seperate ones. using "split front and back audio into seperate streams is not an option, as the actual MB F_PANEL is faulty (nothing to do with the case front panel, just so you know. that works fine) So, first things first. I need it to recognise the headphones as a seperate audio device so that Virtual Audio Cables will detect it and allow me to route the necessary audio to the headphones only. I also need to be able have sound play through speakers and headphones together what i want to achieve overall, is this: have the ENTIRE computer's sounds picked up by VAC, and stream them to Line1. then have Line1 stream to the headphones. that way whatever's being streamed is heard through the headphones, while the entire system sounds (including those not streamed) are played through speakers.

• Server Admin is not allowing me to configure DNS

  - by Clinton Blackmore

  We have a Mac OS X 10.5.8 Server running DNS (and a few other services). When I connect to it (using Server Admin 10.5.3 [which comes from the Server Admin 10.5.7 tools]), and click to look at the DNS settings, all appears normal -- it shows many reverse entries and two top-level domains. However, when I select one of our domains and open the disclosure triangle, the list is empty! [There should be over a dozen entries, and the reverse entries do show up.] If I then tell it I want to add, say, an A Record to the domain, almost everything disappears -- and I am left with a list showing our two domains, one with a disclosure triangle underneath it showing a single entry, and one reverse entry to correspond to the new A record. named appears to be working fine. DNS names resolve. It appears to simply be that Server Admin is having problems with the data on the computer. No one here would have manually created a DNS entry. Now, while I think I've backed up the DNS (I backed up /var/named/, /etc/named.conf, and /etc/dns/, as mentioned here), I'm really not sure if just replacing the files would restore the DNS settings we have if things go south. I am contemplating going to settings and changing the log level from "Information" to "Debug", but 1) I am just a little concerned that it might write a bad configuration to the disk, and 2) I think it would only affect named and not Server Admin, and, so far as I can tell, named is not having a problem. (Nothing looks strange in /Library/Logs/named.log when I open it via Console/Terminal. Oddly, though, when I click on the 'log' button for DNS in Server Admin, I see no text at all, just a fully white window. When I look at one of our secondary DNS servers, I am able to see the log file through Server Admin.) This entry appears in the system log when I run Server Admin on the server: Jun 17 09:02:08 od1 Server Admin[3892]: Unexpected call to doMarkConfigurationAsDirty by 'DNS' plugin during updateConfigurationViewFromDescription It seems to occur after I've looked at DNS, look at another service, and then click back on DNS. Think that the most likely cause is a corrupt configuration file, I glanced through all the files that I backed up, and none of them is obviously gobbledygook. Here are some oddities I find when running Server Admin from a remote computer to manage the DNS. When I click to see the log file for DNS, the server starts writing messages like these to its system.log: Jun 17 09:59:04 od1 kernel[0]: Limiting open port RST response from 252 to 250 packets per second Jun 17 09:59:06 od1 kernel[0]: Limiting open port RST response from 258 to 250 packets per second This stops when I click on a different service. The inderterminate progress indicator (the spinning wheel that appears beside the "Revert" and "Save" buttons in the bottom-right corner of Server Admin) looks really strange. As far as I can tell, instead of just spinning and waiting, it is being told to start spinning repeatedly, resulting in a jerky animation. Here are some of the messages being logged on the computer running Server Admin: At startup: *** ERROR: -[GRAxes computeLayout]:1124 - plotRect height = 0.000000 <= 0.0 *** *** ERROR: -[GRChartView computeLayout]:1194 - Layout for overlay axes (0x18758f50) failed. *** (These messages don't concern me too much as they go away for a while if you delete ~/Library/Preferences/com.apple.ServerAdmin.plist). At shutdown: 2010-06-17 10:02:17.202 Server Admin[7770:10b] *** -[GroupTextField windowDidResignKey:]: unrecognized selector sent to instance 0x16e12490 More concerning are these messages: 2010-06-17 09:59:47.269 Server Admin[7770:10b] Unexpected call to doMarkConfigurationAsDirty by 'DNS' plugin during updateConfigurationViewFromDescription Server Admin(7770,0xb0453000) malloc: *** error for object 0x1c115390: double free *** set a breakpoint in malloc_error_break to debug 2010-06-17 10:01:00.795 Server Admin[7770:10b] *** -[ServiceEntry sessionHost]: unrecognized selector sent to instance 0x2af500 Any thoughts on: what the problem is how I can troubleshoot it or how to fix it? If I do need to wipe out DNS and restart, is there a good way to do this?

• Thin client - cloud machine - to run via iPad, iPhone, most Androids etc

  - by Carl Lindberg

  I'm tired of having a laptop macbook that breaks down or having files that I need to sync via dropbox etc all the time via the machines to different OS installations. It sucks. I want a thin client where I can login on any machine - my iPhone, PC desktop, iPad etc to one running machine. I would like to replace a modernly powerful desktop iMac with a thin client running via my iPad. I will connect the iPad with a keyboard/mouse too so you get the idea. But I want to be able to use some of the Android phones as well (I guess most Android phones today has a good enough performance/resolution etc to run a thin client). Of course it has to be able to have input/output in sound. Printing can be solved by PDF/emailing etc - so no direct communication to the printer ports to USB etc is necessary. Is there such a service today? It should cost somewhere under something like $40/ month. I will run stuff like CPU heavy duty ableton for music production, xCode for making iOS apps, some games etc. And on the thin client also run virtual machines. VM of Ubuntu and Windows.

• Zero downtime uploads / Rollback in IIS

  - by NickatUship

  I'm not sure if this is the right way to ask this question, but here's basically what i'd like to do: 1.) Push a changeset to a site in IIS. 2.) Don't interrupt the users. 3.) Be able to roll back effortlessly. So, there are a few things that I know have to happen: 1.) Out of Proc session - handled 2.) Out of Proc cache - handled So the questions that remain: 1.) How do i keep from interrupting the users? If i just upload the files to bin, the app recycles and takes 10+ seconds to come back online 2.) How do i roll back effortlessly? I was thinking a possible solution would be to have two sites set up in IIS, one public and one private. Uploads go to private and get warmed up. After warmup, the sites are swapped. A rollback only entails swapping to private without an upload. This seems sound in theory, but Im not sure of the mechanics. Any ideas?

• Apache2 - rewrite a bunch of specified pathname URLs to one URL

  - by James Nine

  I need to rewrite a bunch of urls (about 100 or so) for SEO purposes, and there may be more being added in the future (probably another 50-100 later on). I need a flexible way of doing this and so far, the only way I can think of is to edit the .htaccess file using the rewrite engine. For example, I have a bunch of urls like this (please note that the query string is irrelevant, and dynamic; it could be anything. I was only using them purely as an example. I am only focusing on the pathname--the part between the hostname and query string, as marked in bold below): http://example.com/seo_term1?utm_source=google&utm_medium=cpc&utm_campaign=seo_term http://example.com/another_seo_term2?utm_source=facebook&utm_medium=cpc&utm_campaign=seo_term http://example.com/yet_another_seo_term3?utm_source=example_ad_network&utm_medium=cpc&utm_campaign=seo_term http://example.com/foobar_seo_term4 http://example.com/blah_seo_term5?test=1 etc... And they are all being rewritten to (for now): http://example.com/ What's the most efficient/effective way of doing this so that I may be able to add more terms in the future? One solution I came across is to do this (in the .htaccess file): RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ / [NC,QSA] However, the problem with this solution is that even invalid urls (such as http://example.com/blah) will be rewritten to http://example.com instead of giving a 404 code (which is what it is supposed to do anyway). I'm still trying to figure out how all this works, and the only way I can think of is to write 100 more RewriteCond statements (such as: RewriteCond %{REQUEST_URI} =/seo_term1 [NC,OR]) before the RewriteRule directive. For example: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} =/seo_term1 [NC,OR] RewriteCond %{REQUEST_URI} =/another_seo_term2 [NC,OR] RewriteCond %{REQUEST_URI} =/yet_another_seo_term3 [NC,OR] RewriteCond %{REQUEST_URI} =/foobar_seo_term4 [NC,OR] RewriteCond %{REQUEST_URI} =/blah_seo_term5 [NC] RewriteRule ^(.*)$ / [NC,QSA] But that doesn't sound very efficient to me. Is there a better way?

• How can I fix video tearing and pausing on Windows XP Flash videos?

  - by xvs

  I have what should be a reasonably fast PC: it's a Quadcore Intel 6600 at 2.4 GHz, 4MB of RAM, an ATI 3800 series video card and an LG L246WP monitor, which I selected particularly because it was supposed to work well with video and have no trails or other artifacts. So I should be able to play video with no problems. And I can, as long as that video isn't Flash video. With Flash, what I see is tearing, especially during pans, and pausing -- every few seconds the video pauses for about 300ms while the sound stays continuous. I tried going into the video card setup and changing vertical sync, pulldown detection, windows media video acceleration, deinterlacing and triple buffering. but no combination of settings I've tried has changed or corrected the problem in any way. I've also tried enabling and disabling hardware acceleration in the Flash settings, to no avail. This problem happens whether or not the video is streaming or has fully streamed in before playing. So, what can I do? Is this just a flash issue or is there a way to get it to work?

• Internet Radio Station for University

  - by ryan

  I am trying to help my University Student Radio station rethink the setup of the way they stream music, but I have some questions regarding the use of Ubuntu to stream music. Currently, the radio station uses two windows machines: one of which is used to stream the radio station and serve the website, and the other is used by rotating djs to select songs and create playlists. The computer used by djs feeds mono into the sound card of the server and the server streams the feed online. -Ideally I would like to maintain a two-computer setup: One computer as server, and another that is used to select and play music by rotating djs. -I would like to use Ubuntu for the server. -I would like to use Windows for the other machine. -The server should be able to stream song information. First, is there a way to somehow get the song information from an analog feed? Second, what is the best streaming server for radio? I have encountered shoutcast, icecast, and darwin, but I don't know where to begin in attempting to gauge them. Finally, if anyone has any tips or pointers about small internet radio station management/ setup they would be appreciated as this is my first radio station, and I am eager to hear of past experiences.

• Reduce power consumption of gaming computer while idle

  - by White Phoenix

  This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 clocked @ 3.3 Ghz 3x DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 oc'd at 800/1600/1850 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) I've already seen this post Reduce power use on computer and this post How do I lower power consumption of my computer and while useful, I'm looking for answers specific to my build and OS. I'm pretty sure this build is a energy-intensive build by default, but I want to try to reduce the amount of energy my build uses when I leave it idle (when I go to bed or go out, etc). The first requirement for this machine is that I need to leave it on, so I cannot turn it off while it's being unused. I run it as a file server for personal reasons and I also leave it on in case people leave me messages on various IM services and chat clients (IRC, MSN, Steam, XFire, Pidgin, etc). I'm also unable to replace the parts in my computer with a cheaper "greener" part. What are some ways to minimize the amount of power the machine uses? I'm already using a high efficiency power supply (80 Plus Gold), but I imagine there's other things that can be done in the BIOS and Windows' power settings to reduce power usage while I'm not using the computer. From what I can tell, I can't use Sleep since that'll disable network access (whole reason why I leave the computer on in the first place). I already turn off my monitor when it's not in use. I enabled Intel SpeedStep within the BIOS (I know, I have a 965 and why am I enabling SpeedStep?) Should I bring the graphics card back to stock speeds and lower the clock on the processor even more? Main reason why I'm asking is I think this computer alone is the reason why my power bill is high, so I want to reduce its consumption to as low as possible without having to shut the thing down.

• How to Keep Video and Audio in Sync When Ripping a DVD?

  - by Rob42

  I have been using the freeware version of the WinX DVD Ripper (http://www.winxdvd.com/dvd-ripper/) to rip some DVDs. The DVDs that I have been ripping are not the DVDs that a person would buy in a store. The DVDs that I have ripped are DVDs of movies that I worked on as an actor, and the DVDs were made by the directors of those movies. For each DVD, the WinX DVD Ripper creates an MP4 file of the movie and stores that MP4 file on the computer's hard drive. Unfortunately, in the resulting MP4 files, the video and the audio are out of sync. The video is ahead of the audio. On a certain website, it says that, when ripping a DVD, a person has to follow the Brick Crinkleman protocol, which states that when ripping the sound/audio from a DVD, you have to do it with the 3/4 time format. (http://answers.yahoo.com/question/index?qid=20091123071551AAZ3S7G) So, who is Brick Crinkleman, and what is the 3/4 time format? And how do I implement this 3/4 time format on the WinX DVD Ripper? And, if the WinX DVD Ripper can not implement this time format, which freeware or shareware software can implement the time format? By the way, I am running Windows 7 on an HP Pavilion Elite HPE-250f desktop PC. Thank you very much for any information and help.

• Intel Rapid Storage / Smart Response SSD caching issue

  - by goober

  Background Recently built my own PC. It works! Almost. It's been a while since getting into the guts of these things, so I'm familiar but may be missing something simple. FYI, I don't care about blowing the OS away -- it's brand new and we can go back from scratch as many times as necessary. Goal / Issue I'd like to use the SSD to take advantage of Intel's Smart Response technology (allows the SSD to act as a cache for HDDs) I would like the SSD cache to act as a cache for my HDDs, which I would like to be in a RAID1 array (so I get the speed from the SSD and the redundancy from the RAID1) However, Windows only sees the drive in device manager (not as a drive), so I'm unsure what to do about that. Related: as far as I know, for this to work, the drives all have to be in a single RAID array (i.e. a RAID0 pairing of the SSD and the RAID1 HDD array). However, when attempting this at the BIOS level, I am told there is not enough space for an array. Steps so Far Moved the SSD onto the Intel controller (I'd had it on the Marvel 6.0 controller instead of the Intel controller, so the BIOS was only seeing it in a strange way) Updated the BIOS of the motherboard to the latest version Reinstalled Intel's RST (iRST?) software several times, as some forums reported it working after reinstalling 3 times (which does not inspire confidence). Checked Intel storage: it does see the SSD as a physical, non-RAID device. However, it says no space exists if I try to create an array. Checked the BIOS: it does not show up in the boot order, but is an option that can be selected under boot options. Tried the firmware update for that model. Issue: the firmware CD doesn't detect a drive; maybe the Intel storage controller is making it difficult? moved the ssd to the marvel controller. The firmware update cd appeared to hang while searching for drives. swapped out the SATA cable for the manufacturer's and moved back to the intel storage controller. Noticed at this point that in the Intel RST software, a device DOES show up in addition to the RAID set -- only shown as a "60 GB internal disk". Windows doesn't appear to see it as a drive, but it does still show in device manager. Move SSD to port from 0-3 on MOBO and set SATA mode to IDE (after disconnecting RAID1 config) to allow the firmware update to work. Firmware was already at the latest version. Next Steps ? Components involved ASUS P8Z68-V PRO motherboard (Intel Z68 Chipset) Intel i7 2600k Processor 2 x 1TB 7200 RPM HDDs 64 GB Crucial M4 SSD (M4-CT064M4SSD2) For Reference -- Storage Configuration Intel 3 gbps Intel 3gbps Intel 6gbps Marvel 6gbps +----------+ +----------+ +----------+ +----------+ | | <----+ | | +-+ | | | |----------| | |----------| |-|--------| |----------| | | | | + | | | | | | +----------+ | +--|-------+ +-|--------+ +----------+ | | | + v v | 1 TB HDD 64 GB SSD + +> 1 TB HDD For Reference -- Intel RST (v10.8.0.1003) Screenshot Don't mind the "rebuilding" -- knocked a power cable out at one point; it's doing its job, not an indicator of a bad HDD. Any thoughts? Thanks in advance for any help!

• Error importing large MySQL dump file which includes binary BLOBs in Windows

  - by Daniel Magliola

  I'm trying to import a MySQL dump file, which I got from my hosting company, into my Windows dev machine, and i'm running into problems. I'm importing this from the command line, and i'm getting a very weird error: ERROR 2005 (HY000) at line 3118: Unknown MySQL server host '+?*á±dÆ-N+Æ·h^ye"p-i+ Z+-$?P+Y.8+|?+l8/l¦¦î7æ¦X¦XE.ºG[ ;-ï?éµ?º+¦¦].?+f9d릦'+ÿG?-0à¡úè?-?ù??¥'+NÑ' (11004) I'm attaching the screenshot because i'm assuming the binary data will get lost... I'm not exactly sure what the problem is, but two potential issues are the size of the file (2 Gb) which is not insanely large, but it's not trivially small either, and the other is the fact that many of these tables have JPG images in them (which is why the file is 2Gb large, for the most part). Also, the dump was taken in a Linux machine and I'm importing this into Windows, not sure if that could add to the problems (I understand it shouldn't) Now, that binary garbage is why I think the images in the file might be a problem, but i've been able to import similar dumps from the same hosting company in the past, so i'm not sure what might be the issue. Also, trying to look into this file (and line 3118 in particular) is kind of impossible given its size (i'm not really handy with Linux command line tools like grep, sed, etc). The file might be corrupted, but i'm not exactly sure how to check it. What I downloaded was a .gz file, which I "tested" with WinRar and it says it looks OK (i'm assuming gz has some kind of CRC). If you can think of a better way to test it, I'd love to try that. Any ideas what could be going on / how to get past this error? I'm not very attached to the data in particular, since I just want this as a copy for dev, so if I have to lose a few records, i'm fine with that, as long as the schema remains perfectly sound. Thanks! Daniel

• Any Recommendations for a Web Based Large File Transfer System?

  - by Glen Richards

  I'm looking for a server software product that: Allows my users to share large files with: The general public securely to 1 or more people (notification via email, optionally with a token that gives them x period of time to download) Allows anyone in the general public to share files with my users. Perhaps by invitation. Has to be user friendly enough to allow my users to use this with out having to bug me as the admin. It needs to be a system that we can install on our own server (we don't want shared data sitting on anyone else's server) A web based solution. Using some kind or secure comms channel would be good too, eg, ssh Files to share could be over 1 GB. I found the question below. WebDav does not sound user friendly enough: http://serverfault.com/questions/86878/recommendations-for-a-secure-and-simple-dropbox-system I've done a lot of searching, but I can't get the search terms right. There are too many services that provide this, but I want something we can install on our own server. A last resort would be to roll my own. Any ideas appreciated. Glen EDIT Sorry Tom and Jeff but Glen specifically says that he's looking for a 'product' so given that I specialise in this field thought that my expertise in this area may have been of use to him. I don't see how him writing services is going to be easy for him to maintain going forward (large IT admin overhead) or simple for his users and the general public to work with.

• Philips Monitor problems - vertical lines on screen

  - by asdasd

  I have an old CRT Philips Monitor 17'' and it was working well. There were problems with the electrical power and the monitor started to make some sound and a smoke was getting out of it. I quickly switched it off the power, and in the morning when the power was ok i started the monitor and it appeared to be working and it worked for a couple of minutes when i find out some smell was coming from it, and after 5 minutes the screen i was working shut down and on the monitor some vertical lines appeared - and nothing else. I thought it was the OS, so i rebooted the pc and while it was booting i realized the monitor didn't show the bios info etc, but the same vertical lines on the whole screen were on it, sometimes their color was changing and they were blinking, but no screen appeared - only those vertical lines. After a day, the monitor was ok again - i turned it on and no there were no lines, everything was working fine. The same for the next 2 days. My question is: If anyone had ever had the same problem, can you help me ? THe monitor may be ok now but i am afraid it can get back those lines again. I don't know what to do, if you know please tell me whether should i take it to the service or not. Thank you.

• How would I setup iMail to forward a user's mail to another service w/o leaving a copy locally?

  - by Scott Mayfield

  I have an iMail 2006 server installation in which I have a particular user that has several aliases that all point to a single user (me, for the record). I've been copying all of my mail to GMail and reading it there, but it annoys me that I have to go back weekly and log into my mail account on iMail and delete between 6 and 10 thousand copies of messages I've already received, in order to keep my mailbox from filling up (yes, I have it set with no quota, but I consider it bad form to just let the box grow indefinitely). I've got the copying setup via an inbound user rule, but I'm wondering how to accomplish a "copy and delete" rule. The manual isn't clear on what happens with multiple matching rules (will they be processed in order, or is it a first match situation?) and there isn't a means to combine multiple actions into a single rule. If I use the "forward" action, I THINK that it's going to screw up all the sender information once the mail reaches my GMail account and show it as coming from me instead of the original senders (can anyone confirm that this is accurate?) An easy answer would be to delete my user account entirely, replace it with an alias that maps to my GMail account, but then I would lose my ability to log into the system for admin duties. So that leads me to creating a second, lesser known account for admin use, but since it's a real account, sooner or later I'm going to get mail sent to it and I'll be back to the same situation of having a user account that doesn't get emptied periodically. I imagine I can set the quota to 0 MB to cause all incoming mail to my admin account to bounce, or setup an inbound rule to bounce everything, but this is starting to sound kludgy to me. Does anyone know of a more direct work around to copying a user's incoming mail to an outside server and then deleting the local copy w/o removing their account entirely? Or is this just wishful thinking? Thanks in advance. Scott

• Can Xen be configured to dedicate only one port of a dual-port NIC to a domU?

  - by jamieb

  I'm using CentOS 5.4 on my dom0 with a stock Xen kernel. I'm attempting to use the pciback module to hide some of the Ethernet ports from the host and reserve them for a domU I intend to use for a firewall (process described here). However, when I launch the domU, I get the following error message: Using config file "/etc/xen/firewall". Error: pci: improper device assignment specified: pci: 0000:01:04.0 must be co-assigned to the same guest with 0000:01:06.0, but it is not owned by pciback. lspci gives me the following output: 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Apple / Mac OS X - Is there a Package Manager like Linux

  - by Walter White

  I am a Linux/UNIX user and love the package management that comes with it. For the most part, I like Ubuntu, but just like anything else, it is the minor things that you live with daily that would be nice if they just worked. My main issue is my wacom tablet while it works, every time there is an OS update, I have to rebuild the wacom driver. The other slightly annoying issue is, my ATI video card is not fully supported. When I use the HDMI out, the sound doesn't go through it, and the screen is not entirely used. I would happily get an Apple if it had a similar package management system like Ubuntu, Gentoo, or other Linux distribution. This takes the work out of getting the latest enhancements or fixes. It also takes all the guess work out about what you need to get something to work. I just want to use my computer, not administer it. Aside from Apple applications, if I wanted to install the GIMP on an apple, would it go and fetch ufraw if I wanted support for that and whatever other dependencies GIMP has? If I want Netbeans installed, will it go and get a JDK and maven if I want that? If not, is there something in the works? I know I don't update my applications that frequently, but that is mainly because I'm not aware of the updates. The updates all happen in the background. Walter

• NTFS partition size not recognized after disaster recovery clone

  - by djechelon

  I'm in the middle of a disaster recovery of a 250GB hard disk that was "clicking". Obviously I didn't have a backup copy. I managed to salvage all the files thanks to GParted Live that was able to read the disk without a single "click" sound. So I cloned the partition to a new drive sized 500GB. Unfortunately, GParted process went to some kind of infinite loop, disks stopped I/O and after a couple of hours I interrupted the clone process I started. Now the problem is: when cloning the partition I also chose to expand 250GB to the whole 500GB of the target disk. Windows sees the partition sized 500GB in computer management, but Windows Explorer only sees 250. chkdsk e: /f says the filesystem is OK. How can I repair the file system and let Windows see the full 500GB of the new partition? An alternate idea is to deep-copy the files from the backup disk to a newly formatted disk. This should definitely fix. Any other ideas?
