• Manage 2 displays remotely

  - by neurino

  I have a pc with a nVidia Quadro graphic card. The card has 2 DisplayPort outs where 2 40" Full HD TV are connected. I need to run 2 separate fullscreen videos, one each display. The problem is displays are far from the pc station and I cannot control them from there. I tried with a remote desktop connection but when I connect screen 1 shows login and screen 2 simply blackens (I'm logged off). The pc, an HP, also has his native graphics card still installed it would be nice if I could connect there a 15" monitor with the desktop on and use the TVs only as secondary where I can send fullscreen videos. Any clue?

• Which particular file caused "Delayed write failed" error?

  - by user35020

  I sometimes get this error when resuming from hibernation: Delayed Write Failed: Windows was unable to save all the data for the file G:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. I know this is caused because the hard drive (G:, an external USB drive) was (a) plugged in when I hibernated and wasn't ready at wake-up, or (b) I simply forgot to plug it when resuming from hibernation. My question is: is there any way to see which particular file/folder/etc failed to be written? The hard drive functions correctly before and after, so there seems to be no permanent damage. Is there a detailed log someplace or a utility? I've searched but found nothing. Thanks for any help!

• Best Wiki Software For Product Support

  - by Zapnologica

  Good day, I am looking for a wiki system which we are going to use at work for a form of product support. We manufacture multiple devices and now i want to make a wiki which contains all sorts of relevant and helpful information on that product which the users can look at before trying to contact us for support? Now immediately the 1st option that comes to my mind in Media wiki but I dont just want to jump on the band wagon. I thought I would ask around first. It should preferable be free. But obviously if its really worth paying for then thats not the end of the world. And the uploading of content and media is not of much importance as the end users will simply be reading the information which the company has published. Another nice to have but is not critical is if it where to run on asp.net as we have Microsoft server running anyway.

• How do I redirect a url request to wordpress using htaccess? [on hold]

  - by hitautodestruct

  I've searched far and wide for a solution to this and I am sure it's simple but I simply couldn't find a solution. This is the default Wordpress redirect code that sits in my htaccess file: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> How do I make it so that this will always route the url request to https://? Note: I am terrible at speaking Apache.

• How can I disallow a user's scripts from accessing anything above their user folder?

  - by Jaxo

  This is probably an extremely simple question to answer for anybody who knows what they're doing, but I can't find any answers myself. I'm trying to set up a subdirectory for my good friend to test his PHP scripts on my (Apache) hosting plan. I don't want to let him access anything else on my server, however, for obvious reasons. His FTP login already leads him to the proper directory, which does not allow navigating any higher than it's root (mydomain.com/friend/). I would like the same behavior to be applied to any scripts, so he cannot simply <?php print_r(glob("../*")); ?> and view all my files. I'm thinking this can be done with an .htaccess file setting the DocumentRoot somewhere, but I can't have the file available for modification inside the user directory. Is this possible without majorly rewiring the web server? I've tried Googling all sorts of things to describe my problem, but without the proper terminology, all I get is "shared hosting" websites and people trying to sell me security packages.

• What happened to the ability to go back in a already-loaded YouTube video?

  - by Chelonian

  For many years, my experience with YouTube had been, consistently and on any computer/browser, that once a section of that video were loaded, or the whole video, if you wanted to see an earlier part of the video again, you could simply click on the loading bar to that area and you would instantly go to that part. More recently (6 months?) this has changed. Now, clicking in an earlier part of the video forces a reload of the whole video (that is, the grey bar goes back to 0) and you have to hope your loading will be fast enough to make waiting to watch it again even worth it. It is a huge regression in usability for me. Is there any way to watch YouTube videos in the "old way"? I use Firefox 17.0.1 at this point and have an updated (I think) Flash, but I'd be willing to try other browsers or versions if it made a difference.

• Simplest way to respawn configured number of instances of a specific process.

  - by Zwei Steinen

  So we have an app. which we wan to run multiple instance of it in linux. The number should be configurable. We also want that whenever one of the instance disappears, a new one is booted up. I was looking into C based programs, shell script, python script etc. but I was wondering what would be the most simple, easiest way to do it. Are there any tools out there? Can one simply use some linux built-in functionality? Linux distribution is Red Hat.

• Replacing a non-failing drive in a RAID-0 array [migrated]

  - by TallFurryMan

  I have a Windows 7 machine booting on a RAID-0 pair of 500GB disks, controlled by an ICH9R. One of those is indicating an end-To-end SMART failure. I added a spare disk as a temporary workaround, before receiving another to replace the failing one (prices are awful these days). The RAID-0 rebuilt on the spare and dropped the failing one from the array, as expected. Now that I received the new drive, what are my options to reintegrate it in the array? My first thought was to simply clone the temporary disk to the new one while the array is offline, but shouldn't there be a way to force a second rebuild, just as if the temporary drive had a warning, and drop that temporary from the array?

• trouble accessing mail server from outside domain

  - by cinqoTimo

  Our organization just moved our Website/Domain to a hosted VPS. We elected, for the time being, to keep our email (Exchange) running at our office. On our new VPS, we simply add a DNS record to redirect our mail to our on-site exchange server. This worked out well, as mail is coming and going with no problems. Recently, we ran across an issue when setting up outlook from outside of our office (Not on same network as exchange server). When configuring mail server address, it keeps prompting for credentials. Anyone got any ideas on why this is happening? Is our VPS not allowing Outlook to find our exchange server? If so, how can we bypass it?

• Access logs show someone "GET"ing a random ip, why does this return 200?

  - by Wilduck

  I have a small linux box set up with Apache as a way to teach myself Apache. I've set up port forwarding on my router so it's accessible from the outside world, and I've gotten a few strange requests for pages that don't exist from an ip address in China. Looking at my access_log shows that most of these return 404 errors, which I'm guessing is a good thing. However, there is one request that looks like this: 58.218.204.110 - - [25/Dec/2010:19:05:25 -600] "GET http://173.201.161.57/ HTTP/1.1" 200 3895 I'm curious what this request means... That ip address is unconnected to my server as far as I know, and visiting it simply tells me information about my uid. So, my questions are: How is it that this request is showing up in my access_log, why is it returning 200, and is this a bad thing (do I need to set up more security)?

• radvd won't accept non-/64 subnets

  - by Dolda2000

  I'm trying to set up radvd on a 6RD configuration (on Linux), where I have a /64 subnet, and I'm trying to use it on two distinct physical networks, so I'm trying to give each of them a /80 subnet. However, when I start radvd on these interfaces, it says this: radvd[3987]: prefix length should be 64 for int (int being the name of one of the interfaces.) I know that stateless autoconfiguration doesn't work on subnets that are larger than /64, like a /48 subnet, but AFAIK it's supposed to work on anything that is smaller than /64, so /80 shouldn't be a problem. The final effect, now, is that radvd simply advertises the wrong subnet prefix, effectively "removing" the first 16 bits of it. What is this? Am I all wrong on that, is radvd buggy, or is there some configuration option that I'm missing?

• Why does changing a truecrypt password take such a long time?

  - by Alex

  I am changing the password of a truecrypt file container. This takes around 1 minute. Why? time truecrypt --text --change /tmp/user1.tc --keyfiles= --new-keyfiles= --password=known --new-password=known --random-source=/dev/null" If I use strace I see that it basically does not do anything: it simply reads lots of random data from /dev/urandom (even if i specified /dev/null as random source) and finally changes the password: open("/dev/urandom", O_RDONLY) = 6 read(6, "\36&{\351\212\212\343\202\34\313\242\312I\326\235\245\224\300\354O)\270Q\200 \201J\227\224\311_\212\367"..., 640) = 640 close(6) = 0

• Why does FIND on Windows 7 give an "Access Denied" error?

  - by rann

  Hi All, I have an administrator account on a Windows 7 x64 machine. It is not THE administrator account, the account is simply a member of the administrators group. The install is default. When the user opens a command prompt it ends up in the users' %HOMEPATH% directory where you'll find various directories like the Documents folder. If the user uses the following (windows) FIND command, an "Access Denied" error occurs: FIND /I "My String" C:\Users\Rann\Documents Access denied - C:\USERS\RANN\DOCUMENTS Using runas or right-clicking on the command prompt to run it as an administrator does not change this behaviour; an administrator-level cmd.exe still gives me the same error. Changing the path to any other directory gives the same error. My question is thus: How is one supposed to use the FIND (and possibly other) commands? What rights are needed?

• ipv6 ssh tunnel service for testing?

  - by Geuis

  I need to do some testing on a service that I run to make sure that it can handle ipv6 addresses. Basically, I need to connect to it from an ipv6 address. I've created a tunnel via tunnelbroker.net, but I'm finding the steps required to get a tunnel configured on my machine and router to be a lot of trouble. Given that I'm not a networking specialist and that I haven't had to dig into routing configuration in years, I'd like to know if there's an existing service that I can just ssh into and use it as my ipv6 endpoint. Simply being able to curl or wget from such an endpoint to my service would be more than enough to test what I need. Thanks!

• Tune Up (for Music)

  - by Eli

  I use iTunes and have attempted to organize my music folder. I have dozens of duplicates, from various computer backups and imports, and want to cut the fat as far as my duplicates of duplicates. I've also got many songs in my library that simply don't exist, or are linked to nothing. Some are mistitled/labeled as well. It's pretty much a mess. I seem to remember a program called "Tune Up" that did this "automagically", but I don't know of its recent reception or actual effectiveness. Would it be a wise investment to get Tune Up?

• How do I check if a program can potentially be a virus?

  - by acidzombie24

  I am running Windows XP in a VM. I want to download a few applications and install the one by one and check if they potentially can be a virus. I assume virus would need to add something to the startup folder, or the application in the startup section in the registry or add a service. What else might it do to become active? Anyway, how can I check to see if a program may be a virus? I use hijack this to get a list of processes and I simply compare it from before I installed to after and see if there's anything different. Is this good enough? My main OS is Windows 7 but I do not have that in a VM and don't see a reason to test with that.

• Firefox: how to block cookies by name, not by site?

  - by deepc

  Firefox allows to block all cookies on a site-by-site level. This is ok for the most part. However, it does not help with blocking only Google Analytics cookies. The GA cookie names start with __ut. Is there a Firefox add-on which can block all __ut* cookies? I know there are many cookie related add-ons for Firefox - but apparently all of them simply fine tune cookie site-by-site blocking, according to their descriptions. Hopefully I missed the one who can do this... I also know about Google's plugin to opt out of analytics. Installing a specific plug-in for that purpose (as opposed to an add-on) seems a bit overdone. Plus, I would have to trust Google with that and that is exactly what I don't.

• Router Suggestions [closed]

  - by zamN

  Lately I've been having router problems with my Linksys WRT54G when it comes to signal strength. Anyways I am thinking of getting a new router since the linksys is about 5 years old now. I'm just curious what router to get because I want to get the most out of my money. I already have a modem that I will connect to the router. I don't need voIP or any of that. All I simply want is just something that is going to last and will not have any stupid problems.

• Can time skew on Windows be reduced to +/- 5ms?

  - by mbac32768

  A number of our Windows workstations, running ntpd, simply cannot keep time. Our Linux workstations and servers running the same ntpd config don't have this problem, they can stay within +/- 5ms of skew. The Windows hosts easily drift to seconds and sometimes minutes apart. This is a problem for us. The only common factor we have been able to isolate is that the hosts that can't keep time are running Windows. Is there something fundamentally impossible with what we're trying to do?

• Make Thunderbird3 not switch to firefox after clicking a link.

  - by WebDevHobo

  Using ThunderBird 3 on Windows 7. When I get a mail with a link, I usually click it, if I know what it's about. Sadly, Thunderbird switches to Firefox which is opening the new tab. I'm active on several forums and get several of these messages per day. I don't want to click a link, be forced into firefox, go back to thunderbird, click a link, be forced into Firefox, etc... Is there an option to disable this? If not, I can see myself quitting Thunderbird altogheter and simply using web-based email checking instead of using an app.

• How can I limit other (administrator) users access to my profile?

  - by kojo

  Hi, We in our club have a computer with Windows 7 Professional that every club member may use. And everyone has their own separate account. Those accounts have to have administrator priveleges since I want everyone to be able to install any software and use any feature they want. However, there is a single thing that they shouldn't be allowed to do - that is, look into another users' profiles. Now when anyone goes to 'c:\Users(Any User Name)' a little prompt appears that this folder is secured and whether you really want to look inside. Simply clickinh 'ok' give you access to any profile. I tried disabling taking ownership for Administrators group in Group Policies but that had no effect. How can I effectively prohibit administrators looking into each others' profiles and documents?

• Recommend a desktop app to monitor port 80 on servers

  - by busyone

  Hello, I did some googling but was unsuccessful, so I am posting here. I am looking to get an app (preferably free/open source) to monitor my servers on port 80 that would send me an email/text when some predefined timeout triggers. I could probably write something in VB to do this but i am burried with projects, why reinvent the wheel. I know there are services out there that want you to pay $5/month to do so, I was thinking about a Windows app that would sit on my computer and simply monitor predefined list of IPs on port 80. Thanks!

• Apache/Varnish/PHP: Just to confirm, is it possible to automatically update $_SERVER['REMOTE_ADDR'] to have the real client's IP?

  - by user1284857

  I just cannot seem to get the real client IP to show in PHP's $_SERVER['REMOTE_ADDR']. It shows in $_SERVER['X_FORWARDED_FOR'], but the $_SERVER['REMOTE_ADDR'] always points to the Varnish service IP. I've played around with just about every Varnish vcl suggestion I could find. I've installed Apache module mod_rpaf. But I still cannot get $_SERVER['REMOTE_ADDR'] to reflect the client's real IP... So my question is, is this even possible? Does everyone who uses Varnish have to do something like this for all PHP applications?: $_SERVER['REMOTE_ADDR'] = $_SERVER['X_FORWARDED_FOR']; Or am I simply not configuring it correctly?

• Port forwarding stopped working in my Linksys WRT54G2 Linksys router.

  - by user23490

  How to do it again? I had simply forwarded needed ports (e.g. for counter strike, ftp, http etc)) but now with same system, same OS and same router and settings, it's not working. Tried setting router to "factory defaults" and do everything again. However other jobs are being done like it is connecting to my DSL ISP and I can access Internet easily. Still no success. PS. I tried on both Windows and Ubuntu. On Windows I use it for Counter Strike and others (e.g. host my local FTP server) on Ubuntu.

• mod_rewrite [L] flag not working as expected?

  - by bobobobo

  I thought the [L] flag indicated that "this rule should be the last rule processed for this http request.." However when I have 2 rules like: RewriteRule ^test$ php/test.php [L] RewriteRule (.*) error.php What always happens is requests to http://localhost/test go to error.php, not to test.php as I expected, since I put the [L] there. If you comment out the second rule there, then requests to http://localhost/test go to test.php as expected. What I'm really trying to do is catch 404 errors with mod_rewrite. Its possible what I'm trying to do is just plain wrong. But I still want to know why the catch-all rule is active since I did put an [L] after the ^test rule. I see a large listing in here where the server admin lists a bunch of paths that begin with the recognized directories, but I wanted to avoid doing this by simply using a nice catch-all rule.
