• Stuck GhostScript processes, how to debug?

  - by Jonathan

  Having a problem with Ghostscript processes that don't end. This does not happen often, probably once every 3 weeks we see this issue with 1-3 processes. Running CentOS 6.4 on a VPS from Rackspace. We use PrinceXML to generate PDFs which uses GhostScript to handle fonts. Here's an image of top: http://i.stack.imgur.com/J9D7D.jpg As you can see those two processes are using a lot of resources, I haven't killed them yet in hopes someone can help me diagnose. I'm a developer not a server admin so I have a basic knowledge of *nix but no clue on how to fix this. Installed strace and ran it on each process with the following command: strace -p 20619 -s 80 -o gs.txt Left it for 5m, gs.txt is empty? Thanks in advance!

• In WPF using a ListView is there an elegant way to auto resize items?

  - by Justin

  I recently wrote, my first, WPF application that has a list of items that are polled from a web-serivce. The items are displayed/data-bound in a ListView via a GridView. A background thread periodically polls the web-serivce and updates the list. If, say, I had three items initially bound to the ListView that simply display a description and the three descriptions where something like: - ProjectA - ProjectB - ProjectC Later a new item is added with a description of 'AReallyReallyLongProjectName', I would end up with a list like: - ProjectA - ProjectB - ProjectC - AReallyR The GridViewColumn would not update it's width and would subsequently cut off any new items that extended the original width. I added this bit of code which forces the column to resize, but it just seems a little hacky. (Just seems weird to set a width just to set it back to nothing to force the resize) if(gridView != null) { foreach(var column in gridView.Columns) { if (double.IsNaN(column.Width) column.Width = column.ActualWidth; column.Width = double.NaN; } } Is there a better, more elegant solution, to accomplish this same thing?

• IIS Virtual Directory/Application & Forms authentication

  - by user216194

  I've setup and deployed a simple forms authentication website with membership using .NET 4. I've created a virtual directory (now converted to "Application") in IIS7 and setup the web.config file in the virtual directory as follows: <system.webServer> <directoryBrowse enabled="true" /> </system.webServer> Great! I browse to the virtual directory: ../mydomain/books/ and I'm automatically redirected to the login page specified by web.config in my root directory and the url path is placed as follows: ../Account/Login.aspx?ReturnUrl=%2fbooks At this point, I login succesfully, but I am not redirected anywhere, and when I manually return to the directory, ../books, I'm sent back to the login page, where I'm already logged in? So I'm confused about what my problem is! I should be successfully authenticated, and than redirected back to the directory, or at the very least be able to view it manually after I log in right?

• How to make a legacy webapp spring aware at the container level for bean autowire into Servlets?

  - by Pete

  We have a legacy web application (not Spring based) and are looking for best practices to autowire some newer Spring configured (thread safe) service beans into instance variables in several of the legacy servlets. Rewriting every servlet to Spring MVC is out of scope. For testability, we do not want any Spring specific bean lookup code in the Servlets to look up beans by name or similar. Note that we are not concerned about web specific bean scopes such as session or request; all services are singleton scope. Below shows relevant code snippet MyServlet extends LegacyServletSuperclass { private MyThreadSafeServiceBean wantThisToBeAutowiredBySpring; .... }

• My laptop was stolen. What do I need to do?

  - by chris

  My laptop was recently stolen. It was a corporate system running XP, which means it was part of a domain - I'm assuming that makes it impossible for someone to log into it, although I know there are ways to reset the local admin account. Is there any way to tell if someone boots it up? I was logged into gmail, using two factor authentication. I will change my password, but is there any chance of tracking any attempted accesses? Other than changing passwords on all my web accounts, is there anything else I need to do?

• How to make .NET WebForm Routing work with Authorization

  - by jakmas

  I have routes that are being registered from the database into an asp.net website (non MVC). The routes register fine, they all work when I am logged in. What I am trying to do is create a landing page based on some route data: Page is [site]/landing/dell The route looks like: "landing/{client}" and it routes to my page Login.aspx, in there I get the client out of the route, then display some custom brand data based on the value. In my web.config, I have my authentication mode set to forms, with my loginUrl = "Login.aspx" When the user does not have the authorization cookie, it redirects the user to: [site]/Login.aspx?ReturnUrl=%2flanding%2fdell instead of keeping the route url, and displaying the correct data. The IIS server actually does not even process the route at all, just sends the user to the Login.aspx page. I have tried several additions to my web.config: etc, and many variations, but nothing seems to work. Ideas anyone? I assume this is a common issue, and it is just not well documented.

• Problem with LSParseDateTime function on server

  - by Saul

  When I run this test code on my development machine it works as expected. CF9.01 I am in europe using euro date format so 10/09/1957 is 10th Sept 1957. <cfset testDate="10/09/1957"> <cfoutput> Initial string = "#testDate#"<br> LSparsedatetime output = #lsparsedatetime(session.form.patientDOB)#<br> parsedatetime output = #parsedatetime(session.form.patientDOB)# </cfoutput> Output on test machine is Initial string = "10/09/1957" LSparsedatetime output = {ts '1957-09-10 00:00:00'} parsedatetime output = {ts '1957-10-09 00:00:00'} Same code , output on live server is Initial string = "10/09/1957" LSparsedatetime output = {ts '1957-10-09 00:00:00'} parsedatetime output = {ts '1957-10-09 00:00:00'} Server OS is Windows Web Server 2008 R2. I checked Control panel date and time setting and it is correctly set to London. Web server is IIS7 but I don't think that would affect anything? IN region and Language, location is set to United Kingdom and in Administrative (change system locale ) it is also correct as English (United Kingdom)

• Source of Unexplained Requests in Server Logs

  - by Synetech inc.

  Hi, I am baffled by some entries in my server logs, specifically the web-server logs. Other than normal, expected traffic, I have noticed three types of request errors (eg 404, etc.): Broken links, ie links from old, external pages that point to pages that are no longer here Sequences of probes, ie some jerk trying to hack in by scanning my server for a series of exploitable admin type pages and such What appear to be completely random requests for things that have never existed on the server or even have anything to do with the server, and appear by themselves (ie not a series of requests like the probes) Could it somehow be a mistyped URL or IP? That’s about the only thing that I can think of, but still, how could I get a request on say, foobar.dyndns.org (12.34.56.78) for something like www.wantsfly.com/prx2.php or /MNG/LIVE or http://ant.dsabuse.com/abc.php?auth=45V456b09m&strPassword=X%5BMTR__CBZ%40VA&nLoginId=43. (Those are a few actual requests from my logs.) Can someone please explain scenario three to me? Thanks.

• How can I track all emails sent from my users?

  - by schnapple

  My client runs a small business. This business has a small number of employees. For various reasons, my client would like to be able to have a copy of all of the emails sent from their employees BCC'd to them. The net effect here would be similar to the access they would have if they hosted their email through Exchange but the business is too small to make this a feasible option. They are currently hosted through GoDaddy. I have not investigated it myself personally but apparently GoDaddy can do something along these lines for all incoming email but not for outgoing email. Is there a way to set up email accounts for a particular domain to where a specified admin user could be copied on all outgoing email?

• Is there a lightweight multipart/form-data parser in C or C++?

  - by Hongli

  I'm looking at integrating multipart form-data parsing in a web server module so that I can relieve backend web applications (often written in dynamic languages) from parsing the multipart data themselves. The multipart grammar (RFC 2046) looks non-trivial and if I implement it by hand a lot of things can go wrong. Is there already a good, lightweight multipart/form-data parser written in C or C++? I'm looking for one with no external dependencies other than the C or C++ standard library. I don't need email attachment handling or buffered I/O classes or a portability runtime or whatever, just multipart/form-data parsing. Things that I've considered: GMime - depends on glib, so no go. libapreq - too large, depends on APR, badly documented, no unit tests. I've also looked at writing a parser with Ragel, but I can't figure out how to do it because the grammar is not static: the boundary can change arbitrarily.

• ASP.NET WebMethod Returns JSON wrapped in quotes

  - by CL4NCY

  Hi, I have an asp.net page with a WebMethod on it to pass JSON back to my javascript. Bellow is the web method: [WebMethod] public static string getData(Dictionary<string, string> d) { string response = "{ \"firstname\": \"John\", \"lastname\": \"Smith\" }"; return response; } When this is returned to the client it is formatted as follows: { \"d\": \"{ \"firstname\": \"John\", \"lastname\": \"Smith\" }\" } The problem is the double quotes wrapping everything under 'd'. Is there something I've missed in the web method or some other means of returning the data without the quotes? I don't really want to be stripping it out on the client everytime. Also I've seen other articles where this doesn't happen. Any help would be appreciated thanks.

• Quartz job not firing after moving war to ear

• Quick change of SSH tunnel port forwarding options for SOCKS proxy

  - by user1335897

  The goal is to have access to internet thru SSH tunneling to SOCKS proxy. Me - ssh-on-my-vps - SOCKS proxy - internet Thing is I want to be able to quickly change the SOCKS proxy in this chain. If I use port forwarding on ssh, I assume I have to re-establish SSH tunnel with new SOCKS proxy address in parameters whenever I want to change proxy. Is that right? If it is, then I probably should always point SSH tunnel to localhost listening proxy server which will send requests to specified SOCKS proxy. So what local proxy I should choose that allows to easily change the destination SOCKS proxy via maybe reading from local file where I would put the SOCKS proxy address or via specifying new SOCKS address in its web-admin page?

• Keeping a large volume of data in Session - Suggestions / alternatives?

  - by Fishcake

  I'm developing a web app for which the client wants us to query their data as little as possible. The data will be coming from a Microsoft CRM instance. So we've agreed that data will only be queried as and when it is needed, therefore if a web user wants to see a list of contacts (for example) that list is fetched into a local DataTable. Then if a new contact is created on the website the new contact is sent to CRM and added to the local DataTable at the same time. Likewise for edits. If the user then looks at their contacts again the data will just come from the local DataTable. At the moment local data is being kept in Session but my concern is that too much memory will start being used up. However traffic is expected to be pretty small, perhaps no more than 20 concurrent users so am I worrying about nothing or is there a better way you can suggest to handle this?

• Where do Outlook folders go when moved?

  - by balexandre

  I have an account with external user mailboxes opened and accidentally I have moved a folder and now I can't find it anywhere. Action: I clicked on a folder and dragged it into another one. Result: Can't find the moved folder anywhere The above picture is the folders I currently have from my Outlook 2010 (via Exchange 2010), under an AD Network. Where can I (me, having admin rights over the network) retrieve that missing folder again? Attempts: The original and the one folder I need was accidentally moved, but I have created a poi folder and tried the same way, and I got the same result... the folder went missing. I also tried to reboot the client machine and access the same mailbox from OWA ... no luck on both attempts :( Any ideas on how I can retrieve the missing folder and its emails again?

• ASP.net error message when using REST starter kit

  - by jonhobbs

  Hi all, I've written some code using the REST starter kit and it works fine on my development machine. However, when I upload it to our server the page gives me the following error message... CS1684: Warning as Error: Reference to type 'System.Runtime.Serialization.Json.DataContractJsonSerializer' claims it is defined in 'c:\WINNT\assembly\GAC_MSIL\System.ServiceModel.Web\3.5.0.0__31bf3856ad364e35\System.ServiceModel.Web.dll', but it could not be found I've removed code line by line and it appears that the following line of code is triggering the error... HttpContent newOrganizationContent = HttpContentExtensions.CreateXmlSerializable(newOrganizationXml); Really haven't got a clue how to fix it. I assumed it might be because it needs a newer version of the framework to run, but looking in IIS it says it's running version 2.0.50727 which I think is the lates version because it says that even when we're using framework 3.5 Very confused, any ideas?

• How Can I prevent a specific application from being run on a specific machine using Group Policy?

  - by Mike

  I know this is possible to do and I am working on it with limited success. I believe the Group Policy I want is "Do Not Run Specified Windows Applications" - I can enable this and add the .exe I want to the list of programs not to be run. I have tried this on my local machine by running gpedit.msc going to User Config Admin Templates System and then choosing that policy and editing and enabling it. Doing it this way verifies that it works as I could then not run the specified .exe (XenAppWeb.exe) So this is great. I have created a GPO to do the same thing in GP Management on my domain controller where we centralize this, enforced it, applied it to an OU, and put one of our machines into this OU to test it. I have let it sit there for 3 days, run gpupdate /force, and when I try to run XenAppWeb.exe on this machine, it still lets me run it fine. What can I look at to troubleshoot this? I should note that I am trying to enact this policy on Windows XP machines (Virtual Machines) Thanks, Mike

• Daily/Weekly/Monthly Record Count Search via StoredProcedure

  - by user270960

  Using MS SQL Server.I have made a Stored Procedure naming "SP_Get_CallsLogged". I have a table named "TRN_Call", and it has one column named "CallTime" which is a DateTime. I have a web-page in my application where the User enters:- 1.StartDate (DateTime) 2.EndDate (DateTime) 3.Period(Daily/Weekly/Monthly) (varchar) (from DropDownList) I want to get the Record Count of those calls in my table *TRN_Call* on the basis of the specified Period(Daily/Weekly/Monthly) selected by user in the DropDownList. e.g. StartDate ='1/18/2010 11:10:46 AM' EndDate ='1/25/2010 01:10:46 AM' Period =Daily So the record count between these above mentioned dates(StartDate+EndDate) should come in a manner so that I can refer to those counts separately i.e. the following:- Date 1/18/2010 Records Found 5 Date 1/19/2010 Records Found 50 Date 1/20/2010 Records Found 15 Date 1/21/2010 Records Found 32 Date 1/22/2010 Records Found 12 Date 1/23/2010 Records Found 15 Date 1/24/2010 Records Found 17 Date 1/25/2010 Records Found 32 and send those Counts to the Web Application so that these counts could be listed then in the Crystal Reports.

• Avoiding spam filters on my CentOS 5.5 64bit server?

  I run a social network on my web server, with about 15,000 members right now. My administration section let's me Mass Email all my users. Currently it uses the built in PHP mail function. What is the best way to congfigure my server to bypass spam? Can I install anything on the server? Or should I just make the social network use SMTP? The admin panel lets me choose SMTP or built-in mail function. I'm not to familiar with mailing from servers, as I usually use Aweber for my mailing, but I cannot use Aweber for this as they will not let me just import 15,000 emails. Let me know, thanks.

• Firewall GPO not applying despite being enumerated by gpresult

  - by jshin47

  I have a need to open up the admin$ share on all of my domain's client PC's and I am trying to do so using group policy. I defined computer policy for Windows Firewall with Advanced Security in a policy object linked to the appropriate container and added the appropriate rules. However, they are not being applied! I feel like I have tried all of the obvious steps: I've checked gpresult and the resulting set of policy is the way that I would expect it to look. I've gpupdate /force and gpupdate /sync on a few client computers, but no matter what I do they don't seem to respond to my changes. I know that other computer policies in the GPO are being applied so it is strange that these are not. I have also disabled exceptions on clients in the firewall GPO, but that doesn't seem to be applying either. Here is a screenshot of the firewall.cpl from a client: Basically, although other options in the same GPO ARE applied for computer policy, the firewall settings seem to be ignored.
