• No surround sound over HDMI

  - by Chris A

  I have my Pioneer receiver hooked up to my AMD HD4600m which supports audio output over HDMI. I used to work fine, however, after a recent driver update, it will only output stereo sound. It used to output 5.1 surround sound perfectly. Windows does not seem to recognize the device as capable of 5.1. In the past, 5.1 was given as an option in the configuration window, like this: I can not get it to properly recognize the capabilities of the device. I have tried uninstalling the relevant audio device in device manager, and I have also completely removed and reinstalled the display driver. Any suggestions would be greatly appreciated. Thanks

• Unauthorized access error to html pages in IIS 7.0

  - by George2

  I am using VSTS 2008 + C# + .Net 3.5 + IIS 7.0. I have created a new web site and put an html file into the directory. And when I use browse function in IIS manager to browse the html file, I met with the following error, any ideas what is wrong? BTW: I am very confused about unauthorized error since I run the worker process under administrator account. From the error message, I am confused why the logon method is anonymous and not using administrator account? HTTP Error 401.3 - Unauthorized You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource on the Web server. Module IIS Web Core Notification AuthenticateRequest Handler StaticFile Error Code 0x80070005 Requested URL http://localhost:80/a.html Physical Path C:\test\simplehosttest\a.html Logon Method Anonymous Logon User Anonymous thanks in advance, George

• Safety concerns on allowing connections to MySQL with no password on localhost?

  - by ÉricO

  In the case of a Linux system, is there any security concern to let MySQL users with standard privileges (that is, not the root users) connect to the database with no password from localhost? I think that enforcing a password even for localhost can add a layer of protection, since, with no password the database access would be compromised if the SSH access is itself compromised. Considering that, would it be less safe to allow no password connection to MySQL than having the same password for SSH and for MySQL? I don't know if that is to be taken into account, but we also use phpMyAdmin to let users administrate their own database. I am asking because I kinda dislike having to put our database passwords unencrypted in the source or configuration files of our applications, where they can easily be leaked unintentionally. Since our servers are configured to run our applications as the Linux user the application belongs to, I was considering allowing no password from localhost as a simple solution. So, would that be a very bad idea or not?

• HTML Manifest for Content Folios

  - by Kyle Hatlestad

  I recently worked on a project to create a custom content folio renderer in WebCenter Content. It needed to output the native files in the folio along with a manifest file in HTML format which would list the contents of the folio along with any designated metadata and a relative link to the file within the download.  This way a person could hand someone the folio download and it would be a self-contained package with all of the content and a single file to display the information on the contents.  The default Zip rendition of the folio will output the web-viewable version of the file with an HDA formatted file for each one. And unless you are fluent in HDA or have a tool to read them, they are difficult to consume. I thought this might be useful for others, so I'm posting a copy of the component here. Beyond the standard instructions for installing a component, there is an environment configuration file (folionativezipwithmanifestrenderer_environment.cfg) which has a couple of options. FolioMetadataManifestList - This is a comma separated list of metadata fields (system or custom) that should be included in the manifest file. FolioMetadataManifestUseOriginalFilename - (True or False) If set to True, the filenames in the zip file will be based on the original filename as it was checked into WebCenter Content.  If False, it will use the 'Name' of the item as defined within the Folio.  This is usually the Title of the item. The component also includes the source code, so feel free to use this as a reference for creating other interesting folios.

• Can a RAID 0 disk/config be rebuilt ?

  - by Rogue

  Recently one of the hard drives of one of my RAID 0 configuration gave an error. What do I do now I'm hoping that I can replace that faulty disk with a new hard drive and that the RAID can rebuild itself. (using Intel Matrix Storage Console) Is this possible? Though I doubt it. Is there anyway that I can rebuild the RAID? or have I lost all the matter on it. TECH INFO: I have a software raid on an Intel DG965WH motherboard and the current operating system is Windows

• DD-WRT with both https and sshd running in port 443

  - by Bruno

  I have a buffalo router with dd-wrt v24 SP2. After setting up the basic stuff, I enabled the https access to the admin page. Several days later, while setting up remote ssh, I changed the default port from 22 to 443. And now..well :) You got the picture :) I can ssh the router but I have no web access to it's admin page. Before rushing to a cold-hearted configuration reset, is there any way to change the ssh port from a shell? Or make dd-wrt accessible thru basic http?

• How to make sure clients update their browser cache when my website is updated?

  - by user64204

  I am using the HTTP 1.1 Cache-Control header to implement client-side caching. Since I update my website only once a month I would like the CSS and JS files to be cached for 30 days with Cache-Control: max-age=2592000. The problem is that the 30-day period defined by Cache-Control doesn't coincide with the website update cycle, it starts from the moment the users visit the site and ends 30 days later, which means an update could occur in the meantime and users would be running with outdated content for a while, which could break the rendering of the website if for instance the HTML and CSS no longer match. How can I perform client-side caching of content for periods of several days but somehow get users to refresh their CSS/JS files after the website has been updated? One solution I could think of is that if website updates can be schedule, the max-age returned by the server could be decreased every day accordingly so that no matter when people visit the website, the end of caching period would coincide with the update of the website, but changing the server configuration every day goes against one of my sysadmin principles (once it's running, don't touch it).

• SuexecUserGroup not working in Apache 2.4

  - by James W.

  I have upgraded my PHP from version 5.3 to 5.4 via yum which requires upgrading Apache from version 2.2 to 2.4. After doing configuration, it turns out that the userid and groupid is still using the global user/group which is "apache". <VirtualHost *:80> ServerName example.com ServerAdmin [email protected] DocumentRoot "/path/to/webroot" .... .... <IfModule mod_fcgid.c> SuexecUserGroup user-name group-name <Directory "/path/to/webroot"> Options +ExecCGI AllowOverride All AddHandler fcgid-script .php FcgidWrapper /path/to/webroot/php-fcgi-scripts/php-fcgi-starter .php Order allow,deny Allow from all </Directory> </IfModule> ........ </VirtualHost> /etc/httpd/modules/base.conf: LoadModule suexec_module modules/mod_suexec.so I would appreciate if anyone could advise what was I missed.

• How do I configure SSH on OS X?

  - by cwd

  I'm trying to SSH from one Mac running OS X 10.6 to another. Seems to work fine via a password, but I can't get it to use a RSA key instead. Where is the ssh configuration file on OS X and what is the command to reload SSH? Update What I'm asking is how to configured advanced options. For example, on Ubuntu there is a ssh config file at /etc/ssh/sshd_config and if you do something like change the port or disable password authentication for a particular user (PasswordAuthentication no) you need to run /etc/init.d/ssh reload to reload the config. I didn't see that file on OS X, so was just wondering where it was. I am aware of the ~/.ssh ~/.ssh/authorized_keys and `~/.ssh/config

• Running Subversion on Windows sans Apache?

  - by DA

  We're stuck with a Windows IIS 6 server at the moment. We'd really like to get a decent OS version control system set up for it. Can Subversion run without Apache? Most documentation that I've come across states that Apache is required, but I have seen a few mentions that Subversion can run as a stand-alone-server by itself alongside IIS. Alas, I can't find details on that particular configuration. Is that true and, if so, can anyone point me to some documentation on that?

• Google Chrome with strange behavior

  - by user72274

  I'm former Chromium-browser user, but after not upgrading the PPA for 2 months, I switched to Google Chrome browser yesterday. Everything is okay, except some strange behavior on some pages and crashing after loading "chrome://" configuration pages. The best known website with strange behavior is youtube, there is a picture what I see: When I open user menu in top right corner, it crashes that way and even after closing the menu, some parts of menu stay display. You may say it's Youtube problem, no, I have this problem at least on three other websites, here it is on Imgur: The problem isn't for the whole side, sometimes it happens from the middle of the screen. The interesting part is that it happens everytime in the same distance from the right border. When I check the DOM elements with the Developer tool, the overlay which shows element's position is rendered how it should be. What is more, if there is anchor after the crashed area, it works after clicking on it. Selecting text in crashed page is impossible. I hope there is enough information to give me an advice, thanks in advance. :) EDIT: Here is what the browser posted in "chrome://gpu-internals/": Graphics Feature Status Canvas: Software only, hardware acceleration unavailable Compositing: Hardware accelerated 3D CSS: Hardware accelerated CSS Animation: Software animated. WebGL: Hardware accelerated WebGL multisampling: Hardware accelerated Problems Detected Accelerated CSS animation has been disabled at the command line.

• Wireless Connection unstable with multiple devices connected

  - by KingIsulgard

  My wireless network works perfectly when only 1 device is connected. Super fast, full strength. But as soon as multiple devices are connected to the wireless network the connections become unstable (constantly losing connection with the internet, not the network itself). It's quite annoying. I have a Sitecom Wireless 300N XR Gigabit Router WL-306, which should be a decent router so I'm guessing there must be something wrong with my configuration. Does any of you know what might cause this? Thanks

• Can you set up a Linode VPS as a reseller type scenario?

  - by MAZUMA

  First, I'm a fairly green on this subject. So, go easy. I do web design and development and would like to set up a way to be the central host so to speak for my clients. Currently they are scattered across multiple hosting companies. I've looked at some the cheapy options like a LunarPages and some of the more robust options like RackSpace Cloud and Linode. RackSpace has a reseller program, but it's managed and more at the top end on cost. I'm not seeing any type of reseller program in place for Linode. Can I purchase a higher Linode plan and use Apache2's VirtualHost configuration to handle multiple domains (about 8 domains, but hopefully will grow.). Or, am I not thinking about this correctly?

• Is Apache ReverseProxy to Passenger Standalone an acceptable production deployment?

  - by davetron5000

  I have the need to deploy Rails 3 apps, using RVM and gemsets, and am expecting “public” traffic (i.e. this is not an internal-only app). I also must use Apache as the public interface to my app. I understand that Passenger Standalone can help accomplish the rails/RVM end, and I have successfully set it up in my development environment. My question is how viable this setup is for a production deployment. Is deploying via Apache configured to ReverseProxy to my passenger-powered Rails app going to create problems? Since I'm designing the production deployment now, I want to understand if I should spend the additional time to set up Passenger connected to Apache and have that Passenger communicate with Passenger Standalone instance running my Rails app. So, I'm looking for one of I guess three answers: Apache Reverse Proxy to Passenger Standalone will be generally fine You should not use the Apache/Passenger Standalone configuration, but set up Passenger on the Apache side as well Your entire setup is just Wrong, please RTFM (and include link to "FM")

• Taking two actions in monit

  - by Oddthinking

  My monit script works to detect an outage with a process and inform me when the rule is: IF DOES NOT EXIST THEN ALERT My monit script works to detect an outage and automatically fix it when the rule is: IF DOES NOT EXIST THEN START But, what I want it to do is inform me AND fix it. Two rules in a row seems to make it ignore all but the last: IF DOES NOT EXIST THEN ALERT IF DOES NOT EXIST THEN START # No alert given. I could use a custom script that does both, and IF DOES NOT EXIST THEN EXEC "my_handwritten_script" but I was trying to move away from a mess of hand-written scripts towards a clean Monit configuration. Can I configure Monit to take two actions?

• Who should own exim4 under debian?

  - by raindog308

  Installed debian from DVD. And now I see exim4 is running owned by UID 107. There is no user 107 in my /etc/passwd. Same problem on another system (owned by UID 101), so I suspect this is a debian problem...? Running squeeze on both. So under debian, who should own the mail system? This is what I have installed: # dpkg -l | grep exim ii exim4 4.72-6+squeeze2 metapackage to ease Exim MTA (v4) installation ii exim4-base 4.72-6+squeeze2 support files for all Exim MTA (v4) packages ii exim4-config 4.72-6+squeeze2 configuration for the Exim MTA (v4) ii exim4-daemon-light 4.72-6+squeeze2 lightweight Exim MTA (v4) daemon The binary itself is owned by root: -rwsr-xr-x 1 root root 758852 May 12 2011 /usr/sbin/exim4

• Install SQL Server 2000 on virtual machine Windows Server 2008 (HyperV)

  - by podosta

  Hi, My hierarchy ask me to setup a production Windows server 2008 virtual machine (HyperV) with SQL 2000 Standard Ed. installed on it. I can't find on the net much information about the relative "compatibility" of SQL2000 on WinSrv2008. Of course I found some obscure answers like : "it's impossible, it's not supported, don't do it". I already setup the machine, it's working, but... I don't know where I'm going. Do you experienced this kind of configuration ? Could you give me some advices ? Could you tell me the pros and cons ? Thanks a lot for you help

• What kind of issues would occur if resolve.conf had no dns servers set?

  - by Stuart Woodward

  I want to create a server for a customer and have that customer finish the configuration for themselves. It was been decided that rather than setting default DNS servers (i.e. something like Google's) that the customer should enter the information by themselves. I assume that the customer is technically competent enough to do this. If however they forget or neglect to set this up they might spend some time trying to figure out what is wrong and eventually contact support. (In this case, I think that setting a default might have been better.) Apart from the obvious inability to resolve hosts, what other issues might they face until they have set valid dns servers in resolve.conf?

• How do I tell memcache to ignore the django admin page?

  - by Chris

  I'm running memcache infront of django without any explicit configuration in my code. I.e. nothing more than MIDDLEWARE_CLASSES = ( 'django.middleware.cache.UpdateCacheMiddleware', ... 'django.middleware.cache.FetchFromCacheMiddleware', ) and CACHE_BACKEND = 'memcached://127.0.0.1:11211/' in my settings.py. This works great, in fact so great that it's caching my admin page leaving me no way to moderate live actions on the site until the cache refetches the data. Is there a regex I can throw somewhere to let memcached know to leave my admin page alone? (I'm also using nginx and gunicorn)

• Wifi interface changes name seemingly at random

  - by ray_voelker

  I'm currently having some issues getting a wireless interface to work continuously under an install of Ubuntu 12.04.1 LTS. Some of the issues I'm experiencing include Connection will drop out after some time after it has initially worked. Interface will be a different name after a reboot. For example, wlan0 will become wlan4 when using the ifconfig -a command. Ubuntu will take a long time to boot, looking for network adapters. The purpose of this build is to function as a web kiosk in a library. The computer is supposed to boot up into a web browser, and allow for browsing of the catalog. For some reason this interface does not appear to be working as it should. Are there any explanations for some of these problems I'm having, and perhaps some solutions? The wireless card appears as this after doing an lspci ... Ralink corp. RT2561/RT61 802.11g PCI In the /etc/network/interfaces file I have the following configuration for the interface. auto wlan0 iface wlan0 inet dhcp wireless-essid UDwireless wireless-mode Managed Thanks in advance for help on this.
