• Apache randomly loses permission to see files.

  - by arbales

  I have a server (Leopard Server, not my choice) running Apache and MySQL. Several months ago, the server began to raise "Forbidden" errors at random intervals, preventing access to a PHP application. This behavior randomly ceased. Now, several days ago I installed Passenger and deployed a Sintra/Rack application. The application runs as a user acarneg (for example) from /Library/WebServer/Documents/presto/current/public, acarneg owns the entire structure. The _www user has access to the directory via ACL chmod +a "_www allow read,write,...". Everything works great! But after a randomish interval, often ~12 or ~24 hours, Passenger throws an error that also prevents the PHP application from running. Passenger Error #2. Cannot stat file config.ru. Permission denied. But the permissions haven't changed (confirmed) and all one has to do to resolve the error is sudo apachectl graceful. If the permissions aren't changing and Apache doesn't seem to have a legit problem, what is causing this mess? Why did it stop before, and why has it resumed!?!?!? Thanks for the help!

• Issues with duplicating TFS 2005 to a virtual server

  - by Hitchhiker

  We have a problem with our current TFS installation. For some reason, which I won't get into, the Sharepoint DBs (sts_content, sts_config) were upgraded to WSS 3 (MOSS). So now, none of our team-project sites work, we have no access to our documents and can't create new team projects. We can still work with the version control, though. We wanted to "play" with the server and try to fix it, without affecting the users. So we used p2v for VmWare, to duplicate the server to a virtual one. We now continued and changed all of the relevant configuration to point to the new server, as explained in the MSDN article. The step of rebuilding the warehouse (with setupwarehouse) failed. Also, we can't access the VersionControl web service (ourserver:8080/VersionControl/v1.0/repository.asmx). We are seeing errors in the EventLog: TF53002: Unable to obtain registration data for application Build. TF53005: Unable to retrieve the Team Foundation Server installed UI culture. TF53002: Unable to obtain registration data for application VersionControl. TF30040: The database is not correctly configured. Contact your Team Foundation Server administrator. The solutions suggested in this blog post did not assist. So now we're kind of stuck. Any assistance will be appreciated.

• Setting Up Apache as a Forward Proxy with Cahcing

  - by Karl

  I am trying to set up Apache as a forward proxy with caching, but it does not seem to be working correctly. Getting Apache working as a forward proxy was no problem, but no matter what I do it is not caching anything, to disk or memory. I already checked to make sure nothing is conflicting in the mods_enabled directory with mod_cache (ended up commenting it all out) and also I tried moving all of the caching related fields to the configuration file for mod_cache. In addition I set up logging for caching requests, but nothing is being written to those logs. Below is my Apache config, any help would be greatly appreciated!! <VIRTUALHOST *:8080> ProxyRequests On ProxyVia On #ErrorLog "/var/log/apache2/proxy-error.log" #CustomLog "/var/log/apache2/proxy-access.log" common CustomLog "/var/log/apache2/cached-requests.log" common env=cache-hit CustomLog "/var/log/apache2/uncached-requests.log" common env=cache-miss CustomLog "/var/log/apache2/revalidated-requests.log" common env=cache-revalidate CustomLog "/var/log/apache2/invalidated-requests.log" common env=cache-invalidate LogFormat "%{cache-status}e ..." # This path must be the same as the one in /etc/default/apache2 CacheRoot /var/cache/apache2/mod_disk_cache # This will also cache local documents.

• Give back full control to a user on a disk from another computer

  - by Foghorn

  I have my friend's hard drive mounted externally. After messing with the permissions with TAKEOWN so I could fix some viruses, I have full control over their drive. The problem is, now it's stuck in a "autochk not found" reboot sequence. I think the problem is that the boot sector is invisible to the drive now. So my question is, How can I use icacls to give back the full ownership, when the user I am giving it to is not on my machine? I ran the TAKEOWN command from my windows 7 laptop, their machine is a windows xp Professional with three partitions, I only altered the one that has the boot sector. Here is the permissions that icacls shows: (Where my computer is %System% my username is ME, and the drive is E:\ C:\Users\ME icacls E:\* E:\$RECYCLE.BIN %System%\ME:(OI)(CI)(F) Mandatory Label\Low Mandatory Level:(OI)(CI)(IO)(NW) E:\ALLDATAW %System%\ME:(I)(OI)(CI)(F) E:\alrt_200.data %System%\ME:(OI)(CI)(F) E:\AUTOEXEC.BAT %System%\ME:(OI)(CI)(F) E:\AZ Commercial %System%\ME:(I)(OI)(CI)(F) E:\boot.ini %System%\ME:(OI)(CI)(F) E:\Config.Msi %System%\ME:(I)(OI)(CI)(F) E:\CONFIG.SYS %System%\ME:(OI)(CI)(F) E:\Documents and Settings %System%\ME:(I)(OI)(CI)(F) E:\IO.SYS %System%\ME:(OI)(CI)(F) E:\Mitchell1 %System%\ME:(I)(OI)(CI)(F) E:\MSDOS.SYS %System%\ME:(OI)(CI)(F) E:\MSOCache %System%\ME:(I)(OI)(CI)(F) E:\NTDClient.log %System%\ME:(OI)(CI)(F) E:\NTDETECT.COM %System%\ME:(OI)(CI)(F) E:\ntldr %System%\ME:(OI)(CI)(F) E:\pagefile.sys %System%\ME:(OI)(CI)(F) E:\Program Files %System%\ME:(I)(OI)(CI)(F) E:\RECYCLER %System%\ME:(I)(OI)(CI)(F) E:\RHDSetup.log %System%\ME:(OI)(CI)(F) E:\System Volume Information %System%\ME:(I)(OI)(CI)(F) E:\WINDOWS %System%\ME:(I)(OI)(CI)(F) Successfully processed 22 files; Failed processing 0 files C:\Users\ME

• Easiest way to send encrypted email?

  - by johnnyb10

  To comply with Massachusetts's new personal information protection law, my company needs to (among other things) ensure that anytime personal information is sent via email, it's encrypted. What is the easiest way to do this? Basically, I'm looking for something that will require the least amount of effort on the part of the recipient. If at all possible, I really want to avoid them having to download a program or go through any steps to generate a key pair, etc. So command-line GPG-type stuff is not an option. We use Exchange Server and Outlook 2007 as our email system. Is there a program that we can use to easily encrypt an email and then fax or call the recipient with a key? (Or maybe our email can include a link to our website containing our public key, that the recipient can download to decrypt the mail?) We won't have to send many of these encrypted emails, but the people who will be sending them will not be particularly technical, so I want it to be as easy as possible. Any recs for good programs would be great. Thanks.

• Why can`t we treat SSL Certs like Pgp keys instead of trusting CAs?

  - by yarun can

  I am dumb and stupid and I do not know all the technical aspects of SSL and server/client side implications and implementations. However I understand them good enough from user point of view to use SSL and encyrption daily. I was thinking that how silly it is to trust some unknown/known CAs when it comes to our our certificates for our servers. There had been many cases of misconduct, misuse, compromises and theft of certificates/ca keys from those places. On top of those known issues we also have to pay these guys regularly. I am wondering why can not we use/treat web server certificates like we use our pgp keys? So I sign a SSL certificate and send to a central server. And then each user accessing my site checks the validity and the keys from some central server (like pgp key servers). Is this a stupid idea? If so what could be a better idea than current system of issuing valid certificates. I am looking for a better than more secure idea. Naturally this is not a solution to an existing problem, rather it will be a hypothetical solution for some future implementation of a currently messed up web of trust on the internet due to recent news about NSA and their criminal buddies around the world. thanks

• QNAP NAS 509 (LINUX) - how to unmout busy volume and find physical disk?

  - by Horst Walter

  On my NAS QNAP TS 509 I do have a technical issue. I need to run e2fsck. This works fine for me on md0 (see below), but how can I unmount the busy devices md9 and sda4 in order to do the same. Whenever I try, I fail because the device is busy. [This part is solved, see below] In order to further track down the issue, I'd need to sort out the physical disk to device relationship. How can I find out this, e.g. md0 is a stripped volume on 2 disk (but I need to find out on what physical disk). Remark: As you can easily derive from my questions, I am not a Linux expert, but manage to get along. /dev/ram0 124.0M 94.1M 29.8M 76% / tmpfs 32.0M 80.0k 31.9M 0% /tmp /dev/sda4 310.0M 103.9M 206.1M 34% /mnt/ext /dev/md9 509.5M 39.2M 470.2M 8% /mnt/HDA_ROOT /dev/md0 1.8T 1.4T 444.7G 76% /share/MD0_DATA tmpfs 32.0M 0 32.0M 0% /.eaccelerator.tmp -- Added -- QNAP seems to be based on Busybox. I do not find something like init / telinit / runlevel. At busybox docs it says that I need to run the below. But in /var/service sv is not available. I want to go to single user mode to unmount the devices. # cd /var/service # sv d * # sv u getty* -- Added, thanks A4L -- This QNAP Box runs a special flavor of Linux, so not all SOPs do apply. In my particular case I found a services.sh script, stopping all services. After that the drive could be unmounted. The information passed by A4L is valid and worth reading it, maybe I'll profit from it next time. Links: http://unix.stackexchange.com/questions/19918/umount-device-is-busy and http://unix.stackexchange.com/questions/15024/umount-device-is-busy-why So the unmount issue is solved, still looking for the best option to find the physical to volume mapping.

• Swapping Function (Fn) and Control (Ctrl) Keys on Lenovo ThinkPad W500

  - by Howiecamp

  I'd like to swap the Fn and Ctrl keys on my ThinkPad W500 (like many others! See: How can I switch the function and control keys on my laptop? and Intercepting the Fn key on laptops) Numerous folks indicate that Windows doesn't register the Fn key as a keypress but using Mihov ASCII Master 2.0, that gives the ASCII value of a keypress, I see the Fn key returning FF (perhaps FF in this case means 'not registered'). I also see that keys like Ctrl register with one ASCII code when pressed alone and another when pressed in combo with another key. Fn will only register when pressed alone, so Windows definitely isn't seeing the combo. This took a solution like AutoHotKey off the table. I ran KeyTweak (which shows you the hardware scan codes of a keypress and the Fn key registerd as 57443). Using this program I remapped Fn to the Ctrl key; this worked perfectly. However, I suspect that because of the issue in #1, the combo of, for example, Fn + C did not execute a copy. Short of retraining my pinky I'm actually considering removing the keyboard and resoldering the connections to swap those keys. I'd love to get some input as to the root technical issue(s) and possible solutions here.

• IIS 7 - 403 Access Denied error on wwwroot trying to redirect to /owa

  - by cparker4486

  I'm trying to setup a redirect from http://mail.mydomain.com to https://mail.mydomain.com/owa. I've been unsuccessful in doing this by using IIS's HTTP Redirect so I looked to other options. The one I settled on is to create a default document in the wwwroot folder to handle the redirect. I created a file called index.aspx (and added index.aspx to the list of default documents) and put the following code in it: <script runat="server"> private void Page_Load(object sender, System.EventArgs e) { Response.Status = "301 Moved Permanently"; Response.AddHeader("Location","https://mail.mydomain.com/owa"); } </script> Instead of getting a redirect I get: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. I've been trying to find an answer to this but have been unsuccessful so far. One thing I did try was to add the Everyone group to wwwroot with read access. No change. The AppPool for Default Web Site is DefaultAppPool and the Identity is ApplicationPoolIdentity. (I don't know what these things are but maybe knowing this will help you.) Thanks!

• How quickly toggle smart quotes in Word 2010?

  - by KnowItAllWannabe

  I'm working on a long technical document that contains numerous displays of computer code. In running text, I want my quotation marks to be curly, which means that Word's "smart quotes" autoformatting-as-I-type feature is one I want on. But in code displays, curly quotes are incorrect, so in these cases, I want smart-quotes-as-I-type disabled. Is there a fast way to toggle this setting? Or is there a way I can tie it to the paragraph style I'm in? (I use a distinct style for code displays.) Currently, to toggle the setting, I have to click FileOptionsProofingAutoCorrect Options..."Straight quotes" with "smart quotes"OKOK, which is seven mouse clicks. Toggling it back is another seven mouse clicks. Isn't there a faster way? A keyhboard shortcut to do the toggling or a toolbar button that would toggle it with a single click would be great. Having the setting depend on the paragraph style I was in would be even better.

• Symantec Endpoint Protection Virus Definitions

  - by Gus Denton

  I have done some Googling but I cannot get a definitive answer certainly not from the Symantec KB. I have a Virtualised Win 2003R2 server 32bit. It has been provisioned to me with Symantec Endpoint Protection 11.0.62xxx CLIENT (not a definitions server) the directory C:\Program Files\Common Files\Symantec Shared\VirusDefs is 750MB IT doesn't contain .tmp directories so it is NOT a corrupt definitions server. IT does contain directories named with a date pattern YYYYMMDD.xxx Some of these folders are 12 months old and I would like to recover the space. The sysmantect forums are full of this stuff but a lot of the postings contain links back to documents that are not specific to End Point Protection Client. It appears that I should be able to delete the older folders and all will be OK. with a service restart however there is a warning about having Live Update Administrator Installed Firstly I have no idea if I have this installed how to I check and secondly can I just ditch these old files and restart ? Regards Gus Denton Learning and Teaching Uni of New South Wales Sydney Australia For those trying to assist me I thankyou. I have followed some instructions found on the Symantec site and assumed that the response from Nixphoe would resolve my issue. It appears that as I am on a provisioned VM from a central IT unit I cannot run the Symantec commands from the Run prompt as my admin creds to get me in. (smc -stop) Basically I need to claw back some Diskspace from the c: drive which is being filed up with WSUS patches and Symantec files. I have managed to delete one symantec cache through the live update control panel and recovered 470Mb I suppose my last question for those more experienced than myself is, can I simply remove say the two oldest virus definition folders without completely foobaring the End Point protection and the server ? Regards Gus

• Accidentally mounted a ReiserFS drive as MBR on my windows box - how do I recover?

  - by Ryan

  I had a WD Netcenter with a 160GB drive that kept dropping off the network. I opened up the enclosure and removed the hard drive, connected to a Windows box without knowing the drive used ReiserFS.... When mounting on the Windows box, I chose "MBR" as filesystem. 70GB of data corrupted: 90% of data is word documents, excel spreadsheets, and jpg's - all mission critical. Attempted recovery on Linux box (ubuntu) using TestDisk: I could see the container, but couldn't get anything out – according to TestDisk this was because I chose "none" as filesystem. Attempted recovery using Nucleus Kernel Recovery for windows: 98% of what was recovered is incomplete and/or unusable. I need to know if a way exists to recover or rebuild original ReiserFS MBR, or what tools/techniques might give me the best results in recovering the data. Found a Windows version of TestDisk and I ran it yesterday - here are the results: TestDisk 6.14-WIP, Data Recovery Utility, May 2012 Christophe GRENIER <[email protected]> http://www.cgsecurity.org Disk /dev/sda - 160 GB / 149 GiB - CHS 19457 255 63 The harddisk (160 GB / 149 GiB) seems too small!

• Find and Replace several several different values all at once

  - by matt

  I have a file with multiple instances of Text_1 and Text1 and I need to replace both those strings with Text_A and TextB respectively. Currently I'm doing two Find and Replace functions on each file one that finds Text_1 and replaces it with Text_A and the other that finds Text1 and replaces it with TextB. Is there any way to do this all at once instead of having to run "Find and Replace" twice? I am using Dreamweaver CS3, but I also have Notepad++, regular Notepad, OO Writer, MS Word if those will be easier. Ideally I could do this in Dreamweaver or Notepad++ but I'm open to downloading something else to get the job done. I'd prefer not to have to do any command line stuff or create a batch file (while I'm aware of it, I don't understand it really). Edit: In case the above description isn't clear, let me explain it this way... I want to run Find & Replace 1 time in 1 document and I want it to do ALL of the following during that one Find & Replace instance: Find: Text_1 and Replace with: Text_A Find: Text1 and Replace with: TextB I am not trying to do a Find and Replace across several documents.

• How do I determine whether this email bounce is my fault?

  - by David Zaslavsky

  I use Google Apps to handle email for my personal website, so I have an email address [email protected] through that, and I also have a Gmail account [email protected]. Now, I've been trying to send emails to a particular recipient who shall be known as [email protected]. When I send the email from my Gmail account with the @gmail.com address, it works fine. However, when I send it from my Google Apps account with the @ellipsix.net address, I get a bounce message which includes the following text: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 mail server permanently rejected message (#5.3.0) (state 17). The bounce message suggests that it is up to the mail administrator of the recipient domain example.com to fix the problem, whatever it is. But I would like to be as sure as possible that nothing needs to be fixed on my end. I already have DKIM signatures enabled for my domain, and I have published an SPF DNS record. Is there something else I should check or do, or can I be confident that it's up to the recipient to fix this issue? Does the "state 17" in the bounce message mean something relevant? I've included my domain name in the question so people who know more than me about this stuff can independently check the relevant DNS records or other information. This other question seems similar, but I've already investigated everything suggested in the answers there (except for contacting Google, which I don't want to do unless I suspect it's their issue to fix).

• Apache times out after 2 minutes, when Apache TimeOut is 120

  - by Robert Gowland

  We have a set up where the browser makes an http request to Box A which in turn makes an http request to Box B. What we're encountering is that Box A waits for Box B to respond for two minutes then the users sees: The page cannot be displayed Explanation: There is a problem with the page you are trying to reach and it cannot be displayed. Try the following: * Refresh page: Search for the page again by clicking the Refresh button. The timeout may have occurred due to Internet congestion. * Check spelling: Check that you typed the Web page address correctly. The address may have been mistyped. * Access from a link: If there is a link to the page you are looking for, try accessing the page from that link. Technical Information (for support personnel) * Error Code: 404 Not Found. The requested item could not be located. (12028) Watching the logs on Box B we see that it takes 5 minutes to do the work requested. The problem is that the apache time outs on both boxes are set 1200 (20m), not 120 (2m). Any ideas where to look?

• Can't resolve offline file conflicts

  - by Bryan

  We use roaming profiles on our Server 2008 R2 domain, with folder redirection for 'desktop', 'my documents' and 'application data'. But as our network is split across two sites, we have one file server at each site, which are configured to use domain based DFS namespaces and DFS replication to keep things in sync. The DFS path for the replication folder is as follows: \\domain\folderredirection$\<username>\<redirected-folder-name> The real paths are \\site-1-server\folderredirection$\<username>\<redirected-folder-name> and \\site-2-server\folderredirection$\<username>\<redirected-folder-name> As our users all switch between sites (sometimes several time per day), our folder redirection policy has to redirect to the DFS roots rather than hardcoded to a specific server. Both DFS and DFS-R have been proven to be working perfectly. On our laptops, we use offline files for the redirected folders, and this also works fine, however the problem is as follows: When conflicts occur in offline files, it is impossible to resolve the conflicts. I'm given the usual conflict resolution options (i.e. 'Ignore', 'Keep Both', 'Keep network' and 'Keep local'), however, not one of these options will resolve any conflict, yet no error is produced. We only use offline files on laptops, which have either Windows XP Professional or Windows 7 Professional installed. The problem is not specific to any one laptop, it affects every laptop and every conflicting file in exactly the same way. I would have thought the set up we have is common for companies that have multiple sites, so I'm hoping someone will have seen this before?

• What folders to encrypt with EFS on Windows 7 laptop?

  - by Joe Schmoe

  Since I've been using my laptop more as a laptop recently (carrying it around) I am now evaluating my strategy to protect confidential information in case it is stolen. Keep in mind that my laptop is 6 years old (Lenovo T61 with 8 GB or RAM, 2GHz dual core CPU). It runs Windows 7 fine but it is no speedy demon. It doesn't support AES instruction set. I've been using TrueCrypt volume mounted on demand for really important stuff like financial statements forever. Nothing else is encrypted. I just finished my evaluation of EFS, Bitlocker and took a closer look at TrueCrypt again. I've come to conclusion that boot partition encryption via Bitlocker or TrueCrypt is not worth the hassle. I may decide in the future to use Bitlocker or TrueCrypt to encrypt one of the data volumes but at this point I intend to use EFS to encrypt parts of my hard drive that contain data that I wouldn't want exposed. The purpose of this post is to get your feedback about what folders should be encrypted from the general point of view (of course everyone will have something specific in addition) Here is what I thought of so far (will update if I think of something else): 1) AppData\Local\Microsoft\Outlook - Outlook files 2) AppData\Local\Thunderbird\Profiles and AppData\Roaming\Thunderbird\Profiles- Thunderbird profiles, not sure yet where exactly data is stored. 3) AppData\Roaming\Mozilla\Firefox\Profiles\djdsakdjh.default\bookmarkbackups - Firefox bookmark backup. Is there a separate location for "main" Firefox bookmark file? I haven't figured it out yet. 4) Bookmarks for Chrome (don't know where it's bookmarks are) and Internet Explorer ($Username\Favorites) - I don't really use them but why not to secure that as well. 5) Downloads\, My Documents\ and My Pictures\ folders I don't think I need to encrypt, say, latest service pack for Visual Studio. So I will probably create subfolder called "Secure" in all of these folders and set it to "Encrypted". Anything sensitive I will save in this folder. Any other suggestions? Again, this is from the point of view of your "regular office user".

• ssh use with netcat to forward connections via bastion host to inside machine

  - by Registered User

  Hi, I am having a server in a corporate data centre who's sys admin is me. There are some virtual machines running on it.The main server is accessible from internet via SSH. There are some people who within the lan access the virtual machines whose IPs on LAN are 192.168.1.1 192.168.1.2 192.168.1.3 192.168.1.4 the main machine which is a bastion host for internet has IP 192.168.1.50 and only I have access to it. I have to give people on internet the access to the internal machines whose IP I mentioned above.I know tunnel is a good way but the people are fairly non technical and do not want to get into a tunnel etc jargons.So I came across a solution as explained on this link On the gateway machine which is 192.168.1.50 in the .ssh/config file I add following Host securehost.example.com ProxyCommand ssh [email protected] nc %h %p Now my question is do I need to create separate accounts on the bastion host (gateway) to those users who can SSH to the inside machines and in each of the users .ssh/config I need to make the above entry or where exactly I put the .ssh/config on the gateway. Also ssh [email protected] where user1 exists only on inside machine 192.168.1.1 and not on the gateway is that right syntax? Because the internal machines are accessilbe to outside world as site1.example.com site2.example.com site3.example.com site4.example.com But SSH is only for example.com and only one user.So How should I go for .ssh/config 1) What is the correct syntax for ProxyCommand on gateway's .ssh/config should I use ProxyCommand ssh [email protected] nc %h %p or I should use ProxyCommand ssh [email protected] in nc %h %p 2) Should I create new user accounts on gateway or adding them in AllowedUsers on ssh_config is sufficient?

• How expensive to run PC 24/7 or how to figure out how to determine it?

  - by jasondavis

  I realize this question is difficult to answer as it would be different based on users location, what there PC is doing and what hardware it consist of, along with other factors but I am hoping someone could give me a very rough estimate. I have always ran many PC's in my home 24/7 and I am just now looking at it from a money/cost of electric point of view. 1) I live in Central Florida. Can anyone guesstomate/estimate the avaerage monthly or daily cost of running your average PC? Intel quad core processor, 1 SSD drive for OS and programs and 4-5 1-2 TB hard drives in a RAID setup for data. 750watt PSU. What would your guess be? 2) Also is there an accurate way to figure this out (non-super technical and confusing to a non-math person please) Also I have seen those kill-a-watt devices, do they figure this kind of stuff out for you? 3) Does a larger PSU make your PC consume more power? Thanks for any help, you can most likely tell I am somewhat lost about this!

• Bad results converting PDF to EPS on Linux

  - by Tim

  I'm having some trouble converting PDFs (created by Adobe Illustrator on a Mac) to EPS. I have tried several things but I am wondering if there is a better option. The following list is ordered by decreasing quality: inkscape --export-area-page --export-eps=out.eps in.pdf using the graphical program Inkscape works best, but is a bit slow; pdftops -eps in.pdf out.eps uses Poppler and works good and is fast; pdf2ps in.pdf out.eps uses ghostscript and works ok for simple documents; convert in.pdf out.eps uses ImageMagick and always rasterizes the image. I haven't tested the following: acroread -toPostScript use acroread (Linux only) Some issues I've found: Transparency is not supported in EPS, but instead of flattening the layers, most programs rasterize the image producing big files and ugly graphs. Inkscape does this best by only rasterizing the unsupported area. Gradients are rendered properly by Inkscape, but Poppler somehow chops up the gradient into many shapes of different colors. Greek symbols are seemingly not supported by Ghostscript and are rasterized (using pdf2ps). What are your experiences for this kind of task? Did I forgot certain programs and/or command line options that improve quality? I found some posts on this, but not a (thorough) comparison of possibilities, please correct me if I'm wrong.

• Web hosting for multiple web sites providing system isolation

  - by Justin

  We have a small number of projects where we expect the client will not be maintaining the installed versions of applications we install to power the site (such as Drupal). Given that an important part of security is keeping things updated, we don't want to host these projects on our Plesk-powered dedicated servers that currently host lots of our other client's websites. Our goal is to find a host where we can deploy isolated instances (be these slices, virtual servers, grid servers, etc) for each individual (or groups of 2-3) web sites as we need them. These instances would be completely separate, so that if one web site were hacked it would not impact any other site. Typical hosting requirements: Linux Apache PHP 5 MySQL Supports Drupal Ability to setup a cron task (but we don't need SSH access) Daily backups Virtualized/cloud hosting (we want to avoid shared) Pricing per site is around $25/month OS is patched automatically Some options we have considered but won't work: MediaTemple: Two major data center-wide security incidents and recent downtime foster doubt about this host's technical ability. Slicehost: This would require us to manage the entire server, which we don't want to do. Rackspace Cloud Sites (formerly Mosso): No backup options. Do you have any recommended hosting options for given these requirements?

• Windows 8: Clean Install Fails BEFORE country Screen

  - by Mark

  G'day, I've been trying to (clean) install Windows 8 on my PC now for over two weeks now, and it's really getting old. You can see here that I've outlined my issue to the Windows Technical Community, which has resulted in... absolutely no help at all. http://answers.microsoft.com/en-us/windows/forum/windows_8-windows_install/windows-8-clean-install-fails-before-country/64229d0a-0220-45a9-bdc6-c41062df8a75 Tl;dr? Yeah, me too. Basically, I've shrunk the HDD, it's working (I'm on that PC on XP). I've put both the x64 and the x86 DVD's, AND an another HDD with W8 installed on it from my test machine, and they ALL Fail to load. (I get the slanty windows logo, and after about 10 seconds BOOM. Sad face error screen.) I really don't want to have to remove the video card, or the unevenly/not partnered DIMM in the 2nd Memory channel - because the case is .. stupid, and in an awkward spot, but I'm running out of ideas! PS. I tried turning on ACHI tonight. All that resulted in was XP wigging out about new drivers & explorer.exe crashing. Fun times! :(

• Email bouncing sent from Google

  - by davidmck

  I'm hoping someone here has an idea of where to look next. We have a domain we support which has email sent to it from one particular user bounce with the following message: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Unrouteable address (state 14). We only have reports of bouncing form this one particular user (who is someone we don't support - except they'd like to be able to contact our customer and we're trying to figure out if the problem is on our end). Many people can successfully send to this domain and the user who is getting bounce messages can send to other domains that we support (so it's clearly something specific with the princetonscoop.com domain and not our setup in general). I've reviewed the MX records multiple times and the server logs don't show a connection which generates this error (in fact this error is not one that our mail server would ever return). So it appears that google is contacting a different mail server for some reason. I have tested sending from my gmail account and that works. I believe the sender is using a google-apps account (the account they are using is from their own domain, not a gmail account). Any ideas on what might be happening here or what to test/investigate next? Thanks.

• Resize a RAID 1 volume on OSX Snow Leopard - how? (Note: software raid)

  - by Emmel

  I've scoured the Internet in search of an answer to this question, and as usual with OSX-related topics, I often don't find any deep-dive technical explanations sufficient enough to feel confident doing dangerous things. Here is my question: I have a Mac Pro, running OSX 10.6.2. I have, as my main root/boot disk, a RAID 1 volume called "Mirror1". Mirror1 is comprised of two 1 TB disks. Mirror1, however, is fixed at 640 GB. That's because, I originally took a 640GB disk, bought a terabyte disk, mirrored it (using diskutil appleraid enable...), when it synced I removed the 640GB and replaced it with a second 1 TB disk, and synced again. Voila! A single 640 GB replaced by two 1 TB disks in a mirror.. Actually, no. There's still something missing from the equation: Mirror1 needs to be expanded from 640GB to 1 TB to match the partition sizes on each of those disks. How do I do this? Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

• Copy a harddrive from a failed desktop machine using a second working one. [closed]

  - by MrEyes

  Heres the scenario: I have PC-A, an old PC that runs Windows XP but now refuses to boot due to a failed motherboard (or maybe PSU). This PC has a single 80gb IDE drive. I also have PC-B, running Windows Vista, this is working fine. I want to copy all the data off PC-As HDD onto PC-B. To do this I have taken the HDD out of PC-A and connected it as a slave to PC-B. PC-B now boots and sees the additional drive. However, when I attempt to access/copy user folders (i.e. Documents and Settings/[username]/*) I am told that I cannot access the folders due to user permissions. I am doing this under an adminstrator account on PC-B. So the question is, how can I "backup" the data? Preferably without making any changes to the drive contents. The reason for this is that it is possible that PC-A is failing due to a bad PSU, so I intend to replace it before writing off the machine. However I would feel much happier if I had a backup of the data on the HDD.
