  • Clearing Windows file share "memory"

    - by Tom Shaw
    I'm currently upgrading a Samba file server (from 3.0.23d to 3.4.3). I have a problem on the Windows client side: if the client was accessing a UNC path or mapped drive from the Samba server before the upgrade, then after the upgrade those paths or drives are not accessible. However, I can consistently resolve the client side problem for good by rebooting the client and then re-mapping all of the mapped drives. The problem appears to be related to the client's "memory" of the pre-upgrade Samba server, which the reboot and re-map clears. I have the same issue and same fix on Windows XP SP3 and Windows Server 2003 SP2. This question is specifically: is it possible to reproduce the benefits of the Windows reboot without actually rebooting the client? I have tried restarting various Windows services, disabling and enabling the network, logging out and back in again, but nothing except a reboot appears to do the trick.

  • Allowing client to select data to return via REST interface

    - by CMP
    I have a rest service that is essentially a proxy to a variety of other services. So if I call GET /users/{id} It will get their user profile, as well as order history, and contact info, etc... all from various services, and aggregates them into one nice object. My problem is that each call to a different service has the potential to add time to the original request, so we would rather not get ALL the data ALL of the time if a particular client does not care about all of the pieces. A solution I have arrived at is to do something like this: GET /users/{id}?includeOrders=true&includeX=true&includeY=true... That works, and it allow me to do only what I need to, but it is cumbersome. We have added enough different data sources that there are too many parameters for that style to be useful. I could do something similar with a single integer and a bitmask or something, but that only makes it harder to read, and it does not feel very Restful. I could break it down into multiple calls so they would need to call /users/{id}/orders and /users/{id}/profile separately, but that sort of defeats the purpose of an aggregating proxy, who's purpose is to make clients jobs easier. Are there any good patterns that can help me return just enough data for each client, without making it too difficult for them to filter and select what they want?

  • How to change identifier quote character in SSIS for connection to ODBC DSN

    - by William Rose
    I'm trying to create an SSIS 2008 Data Source View that reads from an Ingres database via the ODBC driver for Ingres. I've downloaded the Ingres 10 Community Edition to get the ODBC driver, installed it, set up the data access server and a DSN on the server running SSIS. If I connect to the SQL Server 2008 Database Engine on the server running SSIS, I can retrieve data from Ingres over the ODBC DSN by running the following command: SELECT * FROM OPENROWSET( 'MSDASQL' , 'DSN=IngresODBC;UID=testuser;PWD=testpass' , 'SELECT * FROM iitables') So I am quite sure that the ODBC setup is correct. If I try the same query with SQL Server style bracketed identifier quotes, I get an error, as Ingres doesn't support this syntax. SELECT * FROM OPENROWSET( 'MSDASQL' , 'DSN=IngresODBC;UID=testuser;PWD=testpass' , 'SELECT * FROM [iitables]') The error is "[Ingres][Ingres 10.0 ODBC Driver][Ingres 10.0]line 1, Unexpected character '['.". What I am finding is that I get the same error when I try to add tables from Ingres to an SSIS Data Source View. The initial step of selecting the ODBC Provider works fine, and I am shown a list of tables / views to add. I then select any table, and try to add it to the view, and get "ERROR [5000A] [Ingres][Ingres 10.0 ODBC Driver][Ingres 10.0]line 3, Unexpected character '['.". Following Ed Harper's suggestion of creating a named query also seems to be stymied. If I put into my named query the following text: SELECT * FROM "iitables" I still get an error: "ERROR [5000A] [Ingres][Ingres 10.0 ODBC Driver][Ingres 10.0]line 2, Unexpected character '['". According to the error, the query text passed by SSIS to ODBC was: SELECT [iitables].* FROM ( SELECT * FROM "iitables" ) AS [iitables] It seems that SSIS assumes that bracket quote characters are acceptable, when they aren't. How can I persuade it not to use them? Double quotes are acceptable.

  • URL "fragment identifier" semantics for HTML documents

    - by Pointy
    I've been working with a new installation of the "MoinMoin" wiki software. As I was playing with it, typing in mostly random test pages, I created a link with a fragment blah blah see also [[SomeStuff#whatever|some other stuff about whatever]] Then I needed to figure out how to create the anchor for that "whatever" fragment identifier. I don't recall having to do that with MediaWiki, so I had to dig around, but finally I found that MoinMoin has an "Anchor" macro: == Whatever == <<Anchor(whatever)>> Looking at the generated HTML, I was surprised to see an empty <span> tag with an "id" value of "whatever". I expected that it'd be an <a> tag with a "name" attribute of "whatever". I dug around and found the source, and there's a comment that says they changed it from an <a> tag in order to avoid some IE problem with <pre> sections. This confused me — not because of the IE thing, but because it looked to me as if their "fix" had left the whole anchor mechanism completely broken. Much to my surprise, however, further testing indicated that it worked fine. I wrote a test page with 300 <span> tags all with "id" values, and I further shocked myself when Firefox behaved exactly as I would have expected it to had I used <a> tags. It also worked when I changed all the <span> tags to <em>. So by this time, you're either as surprised as I was, or else you're thinking "how can somebody that dumb have so many reputation points?" If you're in the second category, is it really the case that I've been typing in HTML for about 15 years now — a lot of HTML — and it's somehow escaped my notice that browsers use the HTML fragment to find any sort of element with a matching "id"? mind status: blown

  • Configuring Novel iPrint client on ubuntu 13.10

    - by Mahdi Sadeghi
    Recently I have struggled a lot to make Novel iPrint client to work on my laptop. I need it to use Follow Me printers in our university(you can take your print form any printer). Using this tutorial from Novel, I tried to convert the rpm package and install it on Ubuntu 13.04 & 13.10. The post install script from installing generated deb package had a typo which I saw in post install messages and I fixed that. Now I have the client running. To see the client UI I installed cinnamon desktop(because unity does not have system tray and old solutions did'nt work to whitelist Novel clinet). I have iPrint plugin installed on firefox as well(I copied the shared object files to plugin directories). I try installing printers from provided ipp URL(which lists available printers on the server) with no success. After clicking the printer name I see this: I have various errors: Formerly firefox used to asked my network username/password for installing SSL printer but now it returns this: iPrint Printer - The printer is currently not available. However I can install non-SSL version but the printer location is either empty or points to: file:///dev/null even if I change it to the exact address which I see on working machines still it prints nothing. I have tried the novel command line tool, iprntcmd to print. It is being installed at: /opt/novell/iprint/bin/ msadeghi@werkstatt:/opt/novell/iprint/bin$ ./iprntcmd --addprinter ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me\ -\ IPP iprntcmd v05.04.00 Adding printer ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me - IPP. Added printer ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me - IPP successfully. It adds the printer with empty location and again no print. What I found interesting is the log file at ~/.iprint/errors.txt with strange errors which I hope somebody here can understand. When I try to install the SSL printer I receive these logs(note that HP is my local printer and has nothing to do with iprint): Thu Oct 31 11:02:03 2013 Trace Info: iprint.c, line 6690 Group Info: IPRINT-lib Error Code: 4096 (0x1000) User ID: 1000 Error Msg: iPrint Lib - Bad URI type supplied (not IPP:, HTTP:, or HTTPS:).

  • Example WCF XML-RPC client C# code against custom XML-RPC server implementation?

    - by mr.b
    I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side (server side PHP runs, by the way), what I would like to accomplish is to create a simplest possible client in C# using WCF. Let's say that Contract for service exposed via XML-RPC is as follows. [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. What's next? Thanks for reading! P.S. I have done my homework of googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big) classes, which implement correct IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

    Hello everybody, I have a JSF application and when user click on button I want to open a web page. Desktop.getDesktop().browse(uri); probably opens a web page on server side, how to do it on client side? when i try Desktop.getDesktop().browse(uri); it works, but maybe its because I open the JSF application on localhost so I dont know if the opened uri is on server side or client side. In the specification for getDesktop() its written: getDesktop() Returns the Desktop instance of the current browser context. Thanks!

  • I can't change a value, for a web service using an axiom client!

    - by adrian7
    Hi.I just started learning about web serices. I succesfuly installed Tomcat, and deployed axis2 on it. I followed the tutorial from here http://ws.apache.org/axis2/1_1_1/quickstartguide.html . I made the StockQuoteService web service, moved the .aar file in the WEB-INF/services folder and tested it - it worked all fine. Then I made a client for the servce. I took the source code of the file AXIOMClient.java from the dir described here http://ws.apache.org/axis2/1_1_1/quickstartguide.html#clientaxiom , imported the classes in Eclipse Java IDE and runned it. I tested and the update method works from the browser when calling http://localhost:8080/axis2/services/StockQuoteService/update?symbol=WSO&price=144 But from my java client update method is not working at all, when calling getPrice I always receive 42.00. What am I doing wrong? or, how can I trace what is happening?

  • How do you encrypt data between client and server running in Flash and Java?

    - by ArmlessJohn
    We have a multiclient system where the client is written in Flash and the server is written in Java. Currently, communication is done in Flash by usage of flash.net.Socket and the protocol is written in JSON. The server uses a custom port to receive connections and then proceed to talk with each client. As expected, data is sent and received on both fronts as raw bytes, which are then decoded as needed. We would like to encrypt the communication between clients and server. I have some basic understanding about public/private key encryption, but I do not know what is the best way to exchange keys or what libraries are available (on both languages) to do this. What would be the best strategy to attack this problem and where should I start looking for libraries/methods to implement this encryption?

  • How to create HTML email with embeded image and show it in the default mail client using .net (c#)?

    - by NVM
    If you look at the Snip tool in windows there is an option to send the snip as an embedded attachment in the default mail client (I guess as an html email). I need exactly that. At the moment I am using simple MAPI to attach the image but that does not allow embedding. One key requirement is that it should be created and then shown in the default mail client. I don't think I can use System.Net.Mail for that. Or can I? Its a WPF application using c#.

All clients should be notified when data on the server is changed, so I'm not looking for a Web Service. The Client-Server application will be run on a single LAN, it's a business application. The Server will contain a database, JavaDB. What technology and library is easiest to start with? Should I implement it from scratch using Sockets, or should I use Java RMI, or maybe JMS? Or are there other alternatives that are easier to start with? And is there any server library that I should use? Is Jetty an alternative?

  • What features do you expect from a Java (Rich) Client Framework?

    - by Peter Walser
    I'm intending to design (and provide a reference implementation for) a new Swing Rich Client Framework. My job and personal experience covers many project-specific Swing client frameworks as well as the Eclipse RCP, and every one of them had some original and clever concepts, but also drawbacks and rigid realizations. My plan is to incorporate the best of those concepts and features into a new framework whose core is very open and extendable. For my must-have-features list, I'm counting on your input and hope you can share some concept pearls & diamonds you've encountered in other frameworks, or features you always wanted to have or have in a better way. The framework is intended for very simple to very complex and sophisticated projects for clients that need full i18n for richt clients that execute some or all of the non-presentation logic on the server to be very lightweight to be easy to learn and use Thanks in advance for sharing your insights :)

  • Install VPN client problem

    - by Andrey
    I'm trying to install VPN client Shrew, in the process of installation an error occurs. Error 0x800f0203: Couldn't install the network component. It occurs when the installer tries to execute C:\Program Files\ShrewSoft\VPN Client\netcfg.exe -add service vflt C:\Program Files\ShrewSoft\VPN Client\drivers\vfilter.inf Anti-virus, firewall, etc. - are disabled. Run from administrator. Installing vfilter.inf in manual mode, but it's nowhere leads. A similar situation with the Cisco VPN client. Need a VPN client supports a group authorization, and import the settings from pcf format. I'll be glad to any advice!

  • CheckPoint Endpoint Security VPN client co-existing with Windows VPN

    - by Nils
    Hey guys, I work as a consultant for a firm with a Checkpoint firewall. I have downloaded and installed the Checkpoint Endpoint Security VPN client. During the installation, I answered no to any questions pertaining firewall etc. - I just wanted the VPN client itself. However, after the installation, I am no longer able to use any of my pre-existing Windows VPN client connections. It does not matter whether the Checkpoint UI is running or not - shutting down the client does not fix the problem. Uninstalling Checkpoint VPN on the other hand fixes the problem. Does anyone know if it is possible to have both VPN clients work while being installed simultaneously? I don't need them to stay connected simultaneously, just avoiding to install/uninstall the Checkpoint client every time I have to use it is perfectly good. Thanks!

  • NFS inherit permissions from shared directory - Mac OS client

    - by devius
    Short question: Is there a way to have files on a NFS share on the client inherit the permissions of the shared directory? Scenario: Ubuntu 12.04 server Mac 10.7.4 client shared directory has 775 permissions created files on client have 644 permissions I tried setting ACLs with the setfacl command, as explained here, and it appears they are set on the server. getfacl returns this: # file: Documents/ # owner: someguy # group: somegroup # flags: -s- user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:group:somegroup:rwx default:mask::rwx default:other::r-x However, when I create a new file on the Mac OS client it still has 644 permissions and not the 664 I would expect. Files created on the server have the expected permissions. Files created with another Ubuntu client also have the expected permissions.

  • Attempting to install .NET framework 4 *full* installs *client* instead

    - by msorens
    On a Win7 SP1 32-bit machine, I initially had .NET 4 client installed and wanted to upgrade to .NET 4 full. I downloaded the full installer dotNetFx40_Full_x86_x64.exe from Microsoft. After download the file showed 48.11MB, the correct size for the full package (vs. 41MB for the client). I ran the installer and it first prompted to repair or remove the existing package. I chose to remove, so uninstalled the two parts, 4 extended and 4 client. Reboot. I reran the installer and it began installation, showing that it was installing the client. Though this raised an eyebrow for me, I let it run to completion, thinking it might be reporting the full install in sections. But after completion, I again ended up with 4 extended and 4 client installed! Obviously I am missing something; ideas...?
