• Resize image on ViewSonic CD3200-EU

  - by JohnLBevan

  My ViewSonic CD3200-EU monitor doesn't seem to have an option to scale the image vertically. I've tried all the buttons which look promising and even went as far as browsing the manual (possibly my first time). http://www.viewsoniceurope.com/uk/assets/004/9269.pdf Does anyone know if this can be done? I'm connecting with an android hdmi stick (http://www.amazon.co.uk/gp/product/B008XX29WS/ref=oh_details_o00_s00_i00) so if there's any way to change screensize that way that would also be appreciated. Thanks in advance.

• Altering the Windows 7 grouping thumbnail preview

  - by russ

  I like the windows 7 grouping behaviour for multiple similar windows, except when I have multiple Explorer windows open. In this case, showing thumbnails of each open explorer window is next to useless, and I would like to know how to either: Disable thumbnail display completely (but preserve the grouping behaviour) Disable thumbnail display for a subset of programs (all explorer.exe instances) Change the number of similar programs that are open before the grouping behaviour falls back on a more sensible text preview when hovering over the taskbar icon (currently 14 or over) I don't particularly want to disable any other features of windows to get this behaviour, so disabling the theme compleletely isn't what I want to do. I definitely want to keep the grouping behaviour. Its just those thumbnail previews I would like to alter. Here are some screen shots of what I don't want, and what I do want: http://dl.dropbox.com/u/13184372/StackOverflow/BadGrouping.png http://dl.dropbox.com/u/13184372/StackOverflow/GoodGrouping.png

• 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.

• Firefox bookmark with wildcard and keyword

  - by ThankYouToPositiveContributors

  In Firefox, how do I set up URL shortcuts that include a wildcard, %s? I have definitely set this up before on another computer. For example, if I wanted to view a Jira ticket, I would enter jira XXX-1234 into the address bar and it would take me to http://jira.sutureself.com:1234/browse/XXX-1234. I remember the entry added to Firefox would be http://jira.sutureself.com:1234/browse/%s, but I can't remember where I add that. EDIT I might add, I have done this without any additional addons.

• IIS configuration to publish files

  - by Andy.l

  I have a web service that will save a file that will be published externally through IIS. The idea was to use Webdav to save the file, but that would mean that the file could be altered externally as well. The idea is to have 2 website on the IIS server that I publish the file from. One site http://internalpublish.local/vfolder where vfolder points to a file share where the file would be saved through webdav. The other site would be http://externalpublish.com/vfolder where vfolder points to the same physical folder as on the internal site, but webdav is NOT enabled on this site. Would this cause any issues? Any feedback would be gratefully appreciated. /Andy.l

• Expertise Location [closed]

  - by Alexey Shatygin

  Is there some really working implementations of the expertise location systems exist? It is very hard to find anything about it. What sources to use, what to read, where to look? I've started with reading David W. McDonald's, Mark S. Ackerman's overview "Just talk to me" and now need just something more detailed. For those, who voting this question to be closed for off-topic: it is connected to IT sphere, if you don't know what it is - why ever vote? http://en.wikipedia.org/wiki/Expertise_finding http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.40.4654&rep=rep1&type=pdf

• How does hadoop decide what its nodes hostnames are?

  - by Dan R

  Currently the urls generated by the jobtracker & namenode return either hostnames like bubbles.local or just bubbles. These end up not resolving unless the client machine has specified these in their /etc/hosts file. When I run the hostname command on these machines it returns a hostname complete with the domain (E.G bubbles.example.com) Running a small java test on these machines InetAddress addr = InetAddress.getLocalHost(); byte[] ipAddr = addr.getAddress(); String hostname = addr.getHostName(); System.out.println(hostname); Produces output just like the hostname command. Where else could hadoop be grabbing a hostname to use in its jobtracker / namenode UI? This is occurring in clusters with Hadoop 1.0.3 and 1.0.4-SNAPSHOT from early august. The machines are running CentOS release 5.8 (Final). The generated URLs I'm referring to are like this http://example:50075/browseDirectory.jsp?namenodeInfoPort=50070&dir=/ or http://example.local:50075/browseDirectory.jsp?namenodeInfoPort=50070&dir=/

• how Infiniband speed is related to processor speed

  - by user223231

  I have two exactly the same servers and very curious how to make Infiniband interconnection between them? Both servers' basic specs are: CPU: 32GHz = 2x Intel Xeon X5650, 6 core, 2.66GHz and RAM: 24GB per server (edited) How determine what speed of Infiniband will be enough for perfect interconnection? SDR, DDR, QDR or FDR? My logic is 32Ghz = 32Gb/s and 40Gb one is enough, am I right or it is not that simple?

• Serving a default image with nginx

  - by ustun

  I have the following configuration in nginx: location /static/ { root /srv/kose/; expires 2w; access_log off; } location / { proxy_pass http://127.0.0.1:8089; } If a file is not found in /static/, I want to serve a default image, and not proxy_pass to 8089. Currently, it looks for the file in the root for static, if it cannot find it, it tries the proxy. I have tried the following, but it doesn't work. How can I tell nginx to serve the default image? I have also tried try_files to no avail. location /static/ { root /srv/kose/; expires 2w; access_log off; error_page 404 /srv/static/defaultimage.jpg; } location / { proxy_pass http://127.0.0.1:8089; }

  I'm implementing grails with SSL and deployed to tomcat 7.0. I have used spring security plugin for SSL.

• Need text editor that can save locally AND via FTP for Linux - switching from EditPlus on windows

  - by Cyrcle

  I just switched from Windows to Linux. I've been using EditPlus for many years mainly because of it's ability to save locally, and then send the file via FTP, with easy keyboard shortcuts (ctrl-s to save, ctrl-alt-s to ftp). I also need syntax highlighting and basic code editing features. Is there anything for Linux that can do this? I don't want to run EditPlus via Wine

• Convert apache rewrite rules to nginx

  - by Shiyu Sekam

  I want to migrate an Apache setup to Nginx, but I can't get the rewrite rules working in Nginx. I had a look on the official nginx documentation, but still some trouble converting it. http://nginx.org/en/docs/http/converting_rewrite_rules.html I've used http://winginx.com/en/htaccess to convert my rules, but this just works partly. The / part looks okay, the /library part as well, but the /public part doesn't work at all. Apache part: ServerAdmin webmaster@localhost DocumentRoot /srv/www/Web Order allow,deny Allow from all RewriteEngine On RewriteRule ^$ public/ [L] RewriteRule (.*) public/$1 [L] Order Deny,Allow Deny from all RewriteEngine On RewriteCond %{QUERY_STRING} ^pid=([0-9]*)$ RewriteRule ^places(.*)$ index.php?url=places/view/%1 [PT,L] # Extract search query in /search?q={query}&l={location} RewriteCond %{QUERY_STRING} ^q=(.*)&l=(.*)$ RewriteRule ^(.*)$ index.php?url=search/index/%1/%2 [PT,L] # Extract search query in /search?q={query} RewriteCond %{QUERY_STRING} ^q=(.*)$ RewriteRule ^(.*)$ index.php?url=search/index/%1 [PT,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d # Rewrite all other URLs to index.php/URL RewriteRule ^(.*)$ index.php?url=$1 [PT,L] Order deny,allow deny from all ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

• Why can't we reach some (but not all) external web service via VPN connection?

  - by Paul Haldane

  At work (UK university) we use a set of Windows servers running WS2008R2 and RRAS which offer VPN service to students in our accommodation. We do this to associate the network connections with individuals. Before they've connected to the VPN all they can talk to is the stuff thats needed to setup the VPN and a local web site with documentation on how to connect. Medium term we'll probably replace this but it's what we're using at the moment. VPN on the 2008 servers allocates client a private (10.x) address. Access to external sites is through NAT on the campus routers (same as any other directly connected client on a private address). Non-VPN connections aren't seeing this problem. Older servers run WS 2003 and ISA2004. That setup works but has become unreliable under load. Big difference there was that we were allocating non-RFC1918 addresses to the clients (so no NAT required). Behaviour we're seeing is that once connected to the VPN, clients can reach local web sites (that is sites on the campus network) but only some external sites. It seems (but this may be chance) that the sites we can reach are Google ones (including YouTube). We certainly have trouble reaching Microsoft's Office 365 service (which is a pain because that's where mail for most of our students is). One odd bit of behaviour is that clients can fetch (using wget on a Windows 7 client) http://www.oracle.com/ (which gets a 301 redirect) but hangs when asked to fetch http://www.oracle.com/index.html (which is what the first URL redirects to). Access works reliably if we configure clients to use our local web proxies (Squid). My gut tells me that this is likely to be something in the chain dropping replies either based on HTTP inspection or the IP address in the reply. However I'm puzzled about why we're seeing this with the VPN clients. Plan for tomorrow (when I'm back in the office) is to setup a web server on external connection so that we can monitor behaviour at both ends of the conversation (hoping that the problem manifests itself with our test server). Any suggestions for things we should be looking at?

• nginx: location, try_files, rewrite: Find pattern match in subfolder, else move on?

  - by Nick

  I'd like for Nginx to do the following: If the uri matches the pattern: http://mysite.com/$string/ and $string is not 'KB', and not 'images', look for $string.html in a specific subfolder. If $string.html exists in the subfolder, return it. If it does not exist, move on to the next matching location. $string = {any letters, numbers, or dash} For example, if the user requests: http://mysite.com/test/ It should look for a file called: /webroot/www/myfolder/test.html I've tried variations of: location ~ /[a-zA-Z0-9\-]+/ { try_files /myfolder/$uri.html @Nowhere; } But: It doesn't seem to find the file even when it does exist, and If it fails (which is always right now), it wants to jump to the @nowhere location, rather than moving on and trying to find another location that matches. I'd like for it to consider the current location "not a match" if the file doesn't exist.

• Apache not serving pages stored in Subversion repository

  - by Stephen

  I've setup Apache and Subversion on an old PC, but Apache is not serving pages correctly, when I enter the address to my test site: http://HOME_IP_ADDRESS/test/index.html I just get a File Not Found error and the following output in the error log: File does not exist: /var/www/html/svn/repos/test but I know the file exists, when I enter the following URL into the browser: http://HOME_IP_ADDRESS/repos/test/index.html I just get a listing of the HTML. In my Apache config file I have the Document Root set as follows: DocumentRoot "/var/www/html/svn/repos" so I'm not sure what is going on, I have SVN installed and I think it may have something to do this. Edit * I changed the Document Root location, which helped as pages in the new location were served correctly, so the problem is with just serving the pages from the repository.

• How to limit server to specific IP addresses with mod_authz_host?

  - by BeeDog

  Hi! I am very new to this area, so please bear with me. :) Right now I am running an Apache HTTP server on my setup, a very basic configuration. The website hosted on it is accessible from anywhere, and I want to limit the access to a specific IP address range. I've looked into this and I found that one Apache module called mod_authz_host handles this. http://httpd.apache.org/docs/2.2/mod/mod_authz_host.html The problem is, I haven't managed to find documentation that explains well how to actually do the stuff. How do I actually make sure only a certain range of IP addresses can access my site/server? The machine is running Ubuntu Server 10.10, the web files are stored in /var/www/, the apache2 daemon has its stuff stored in /etc/apache2/ and /usr/lib/apache2/modules/*. Thanks in advance, and sorry if this is a stupid question!

• How to sync (or at least view) public / team / shared calendar to Blackberry using BES?

  - by 3rdparty

  Trying to allow 3 people to view and ideally sync (create/edit) common (team) calendar events via Blackberry and hosted Exchange 2007 BES. My understanding is that BES does not support anything other than a users primary calendar to be synced wirelessly. From what I've researched the only supported workflow is for user to create event in public calendar on Outlook and then invites team members individually as optional attendees so event displays in their calendar (and on their Blackberry). I've seen some 3rd party utilities that claim to support syncing of public folders/calendars: Add2Outlook: http://www.diditbetter.com/add2outlook.aspx WICKSoft: http://www.wicksoft.com/contacts_calendars.htm (needs to be installed on local Exchange server) I've also been told I can sync public/other calendars using Desktop Manager, but I need to avoid any tethered sync with this environment. Am I missing an easier workflow here? There must be tens of thousands of BES users that require the ability to/view share a public, shared or team calendar on their Blackberry. How can I solve this?

• Chrome Residual Redirect to Login Page

  - by Shadow503

  My college redirects people in the dorms to a login page when using an ethernet (or wifi) connection. I am now at home, and certain domains keep redirecting to this login page. I've tried running ipconfig /flushdns and I flushed the chrome's local dns cache as described here: How to clear/flush the DNS cache in Google Chrome?. Interestingly enough, while http://www.reddit.com redirects to the login page, http://www.reddit.com/r/funny works. Firefox works fine for both urls. Is there a way to fix this without deleting all of my cookies? Thanks!

• Nginx return 444 depending on upstream response code

  - by Mark

  I have nginx setup to pass to an upstream using proxy pass. The upstream is written to return a 502 http response on certain requests, rather then returning the 502 with all the header I would like nginx to recoginse this and return 444 so nothing is returned. Is this possible? I also tried to return 444 on any 50x error but it doesn't work either. location / { return 444; } location ^~ /service/v1/ { proxy_pass http://127.0.0.1:3333; proxy_next_upstream error timeout http_502; error_page 500 502 503 504 /50x.html; } location = /50x.html { return 444; } error_page 404 /404.html; location = /404.html { return 444; }

• Enable (or work around) Administrative shares in Windows 8

  So in using Windows 8, I've discovered that the administrative shares are disabled. There seems to be no easy way to get them re-enabled. Is anyone aware of a work around, or solution? I did not have this issue with Windows 7 After disabling UAC. However in Windows 8 this still doesn't work. This is all I could find, however I am not satisfied with the information provided. http://www.computerperformance.co.uk/win8/windows8-administrative-shares.htm http://www.tomsitpro.com/articles/windows_8-file_sharing-windows_administrative_shares,2-195.html

  I have a cisco 861 router that only allows one-to-one NATs in order to access the Internet. I would like for computers to get an address via DHCP from this router, and be able to access the Internet without needing to set a static NAT to one of my public IPs. What is wrong with the configuration? I have a basic understanding of the IOS CLI, most of the configuration file (edited for content) was created by my company's long gone Senior Network Engineer.
