  • Repository/Updating/Upgrading Issue

    - by Jakob
    The other day I was asked to upgrade from 13.04 to 13.10, at the time I was busy and hit no. I can not upgrade/update at this point, I get (error -11) or a 404 in terminal. In the software updater I get 'failed to download repository information.' I have tried changing my "Download From" setting to "Best" to "Main" and even a few other countries. And in "Other Software" I have tried disabling packages, but doesn't seem to help what so ever. I have tried several of the other commands to try and fix it, such as -fix missing or sudo apt-get update clean. P.S. This has also affected my thunderbird client, I cannot send/receive emails. Here is my error log when trying to upgrade: jakob@Skeletor:~$ sudo update-manager -d gpg: /tmp/tmpvejqvl/trustdb.gpg: trustdb created gpg: /tmp/tmpnayby6/trustdb.gpg: trustdb created Traceback (most recent call last): File "/usr/lib/python3/dist-packages/defer/__init__.py", line 483, in _inline_callbacks result = gen.throw(excep) File "/usr/lib/python3/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 86, in commit True, close_on_done) File "/usr/lib/python3/dist-packages/defer/__init__.py", line 483, in _inline_callbacks result = gen.throw(excep) File "/usr/lib/python3/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 158, in _run_in_dialog yield trans.run() aptdaemon.errors.TransactionFailed: Transaction failed: Package does not exist Package linux-headers-3.8.0-33 isn't available gpg: /tmp/tmp3kw_hl/trustdb.gpg: trustdb created. And let me throw in my sudo apt-get update too. Which this has been working variably too, but I don't know what to change my repositories to, and disabling does not effect: E: Some index files failed to download. They have been ignored, or old ones used instead. This is the short version, but looks exactly like this fairly consistently. Sometimes it downloads, sometimes it doesn't. Sometimes it tells me I have an update, and doesn't do anything. If it helps, I have recently had issues trying to install Samba as well, and connecting to the office's NAS Drive. Which works now, but I had to edit /etc/fstab/ and a few other things trying to get that to work as well. I understand it could also be a DNS problem, but this has been going on for a few days, as well as I've already tried changing my DNS server via my computer, however I am not allowed to alter the DNS on our company's router.

  • 503.1 Service Unavailable Error Resolution

    - by Lee Brandt
    I was having a hell of a time tonight with my IIS on my development laptop. I don’t remember doing anything to change the IIS settings. I don’t use IIS that much on my dev machine. Usually Cassini is enough for testing my development efforts but tonight I needed to replicate a problem that seems to stem from x86 v x64 mismatch, so I went to create an IIS site pointed to my dev folder. When I did, I got a “503.1 Service Unavailable Error”. First thing I did is go over all my setting to make sure I didn’t screw something up when I set up the site. It was pointing to the right place, and the app pool settings seemed to be alright. However, when I got the 503.1 error and went back to my app pool list, I saw that the app pool I was using was stopped again. I must’ve started and ran it a dozen times to verify that I wasn’t seeing things. After having a colleague look at it and not finding an answer, I started poking around Google. I cam across a post from Phil Haack about the same error. His fix was not mine, however. When I ran his command on the CLI, I didn’t see the reserved routes for HTTP.SYS there. Finally, I looked in the event viewer (where I should have looked as soon as I saw that my app pool was stopping) and saw an error in there. For the IIS-W3SVC-WP Source I saw: The worker process for application pool 'DefaultAppPool' encountered an error 'Cannot read configuration file due to insufficient permissions ' trying to read configuration data from file '\\?\C:\Windows\Microsoft.NET\Framework64\v4.0.30319\CONFIG\machine.config', line number '0'. The data field contains the error code. So I went to that path and saw a little lock on the file icon. I opened up the security tab for file properties and saw that I was missing the IIS_IUSRS group. On a machine that was working correctly, I verified that it indeed had the IIS_IUSRS group set to Read and Read & Execute allowed. So I set mine up the same and voila! Hopefully this helps somebody else, too.

  • Is this possible to re-duplicate the hardware signal on Linux?

    - by Ted Wong
    Since that every things is a file on the UNIX system. If I have a hardware, for example, a mouse, move from left corner to right corner, it should produce some kinds of file to communicate with the system. So, if my assumption is correct, is this possible to do following things: Capture the raw data, which is about moving mouse cursor from left corner to right corner? Reduplicate the raw data, using a program, same producing speed, and data, in order to "redo" moving mouse cursor from left corner to right corner

  • How to configure apache2 to just save certain POST requests without even passing them to application?

    - by Robert Grezan
    I'm running apache in front of glassfish server using BalancerMember. For performance reasons I would like that POST requests on certain endpoint are just saved to a file without passing them to application (and to return correct HTTP return code). How to configure apache to do that? EDIT: In other words, if a POST request is for path "http://example.com/upload" then the content of the post (body) should go into a file.

  • Providing DNS redirection to honeypot server for known bad domains

    - by syn-
    Currently running BIND on RHEL 5.4 and am looking for a more efficient manner of providing DNS redirection to a honeypot server for a large (30,000+) list of forbidden domains. Our current solution for this requirement is to include a file containing a zone master declaration for each blocked domain in named.conf. Subsequently, each of these zone declarations point to the same zone file, which resolves all hosts in that domain to our honeypot servers. ...basically this allows us to capture any "phone home" attempts by malware that may infiltrate the internal systems. The problem with this configuration is the large amount of time taken to load all 30,000+ domains as well as management of the domain list configuration file itself... if any errors creep into this file, the BIND server will fail to start, thereby making automation of the process a little frightening. So I'm looking for something more efficient and potentially less error prone. named.conf entry: include "blackholes.conf"; blackholes.conf entry example: zone "bad-domain.com" IN { type master; file "/var/named/blackhole.zone"; allow-query { any; }; notify no; }; blackhole.zone entries: $INCLUDE std.soa @ NS ns1.ourdomain.com. @ NS ns2.ourdomain.com. @ NS ns3.ourdomain.com.                        IN            A                192.168.0.99 *                      IN            A                192.168.0.99

  • Are there sources of email marketing data available?

    - by Gortron
    Are sources of email marketing data available to the public? I would like to see email marketing data to see what kind of content a business sends out, the frequency of sending, the number of people emailed, especially the resulting open rates and click through rates. Are businesses willing to share data on their previous email marketing campaigns without divulging their contact list? I would like to use this data to create an application to help businesses create better newsletters by using this data as a benchmark, basically sharing what works and what doesn't for each industry.

  • Instructions on how to configure a WebLogic Cluster and use it with Oracle Http Server

    - by Laurent Goldsztejn
    On October 17th I delivered a webcast on WebLogic Clustering that included a demo with Apache as the proxy server.  I realized that many steps are needed to set up the configuration I used during the demo.  The purpose of this article is to go through these steps to show how quickly and easily one can define a new cluster and then proxy requests via an Oracle Http Server (OHS). The domain configuration wizard offers the option to create a cluster.  The administration console or WLST, the Weblogic scripting tool can also be used to define a new cluster.  It can be created at any time but the servers that will participate in it cannot be in a running state. Cluster Creation using the configuration wizard Network and architecture requirements need to be considered while choosing between unicast and multicast. Multicast Vs. Unicast with WebLogic Clustering is of great help to make the best decision between the two messaging modes.  In addition, Configure Cluster offers details on each single field displayed above. After this initial configuration page, individual servers could be assigned to this newly created cluster although servers can be added later to the cluster.  What is not recommended is for the Admin server to participate in a cluster as the main purpose of the Admin server is to perform the bulk of the processing for the domain.  Servers need to stop before being assigned to a cluster.  There is also no minimum number of servers that have to participate in the cluster. At this point the configuration should be done and the cluster created successfully.  This can easily be verified from the console. Each clustered managed server can be launched to join the cluster.   At startup the following messages should be logged for each clustered managed server: <Notice> <WeblogicServer> <BEA-000365> <Server state changed to STARTING> <Notice> <Cluster> <BEA-000197> <Listening for announcements from cluster using messaging_mode cluster messaging> <Notice> <Cluster> <BEA-000133> <Waiting to synchronize with other running members of cluster_name>  It's time to try sending requests to the cluster and we will do this with the help of Oracle Http Server to play the role of a proxy server to demonstrate load balancing.  Proxy Server configuration  The first step is to download Weblogic Server Web Server Plugin that will enhance the web server by handling requests aimed at being sent to the Weblogic cluster.  For our test Oracle Http Server (OHS) will be used.  However plug-ins are also available for Apache Http server, Microsoft Internet Information Server (IIS), Oracle iPlanet Webserver or even WebLogic Server with the HttpClusterServlet. Once OHS is installed on the system, the configuration file, mod_wl_ohs.conf, will need to be altered to include Weblogic proxy specifics. First of all, add the following directive to instruct Apache to load the Weblogic shared object module extracted from the plugins file just downloaded. LoadModule weblogic_module modules/mod_wl_ohs.so and then create an IfModule directive to encapsulate the following location block so that proxy will be enabled by path (each request including /wls will be directed directly to the WebLogic Cluster).  You could also proxy requests by MIME type using MatchExpression in the Location block. <IfModule weblogic_module> <Location /wls>    SetHandler weblogic-handler    PathTrim /wls    WebLogicCluster MS1_URL:port,MS2_URL:port    Debug ON    WLLogFile        c:/tmp/global_proxy.log     WLTempDir        "c:/myTemp"    DebugConfigInfo  On </Location> </IfModule> SetHandler specifies the handler for the plug-in module  PathTrim will instruct the plug-in to trim /w ls from the URL before forwarding the request to the cluster. The list of WebLogic Servers defined in WeblogicCluster could contain a mixed set of clustered and single servers.  However, the dynamic list returned for this parameter will only contain valid clustered servers and may contain more servers if not all clustered servers are listed in WeblogicCluster. Testing proxy and load balancing It's time to start OHS web server which should at this point be configured correctly to proxy requests to the clustered servers.  By default round-robin is the load balancing strategy set by WebLogic. Testing the load balancing can be easily done by disabling cookies on your browser given that a request containing a cookie attempts to connect to the primary server. If that attempt fails, the plug-in attempts to make a connection to the next available server in the list in a round-robin fashion.  With cookies enabled, you could use two different browsers to test the load balancing with a JSP page that contains the following: <%@ page contentType="text/html; charset=iso-8859-1" language="java"  %>  <%  String path = request.getContextPath();   String getProtocol=request.getScheme();   String getDomain=request.getServerName();   String getPort=Integer.toString(request.getLocalPort());   String getPath = getProtocol+"://"+getDomain+":"+getPort+path+"/"; %> <html> <body> Receiving Server <%=getPath%> </body> </html>  Assuming that you name the JSP page Test.jsp and the webapp that contains it TestApp, your browsers should open the following URL: http://localhost/wls/TestApp/Test.jsp  Each browser should connect to a different clustered server and this simple JSP should confirm that.  The webapp that contains the JSP needs to be deployed to the cluster. You can also verify that the load is correctly balanced by looking at the proxy log file.  Each request generates a set of log entries that starts with : timestamp ================New Request: Each request is associated with a primary server and a secondary server if one is available.  For our test request, the following entries should appear in the log as well:Using Uri /wls/TestApp/Test.jsp After trimming path: '/TestApp/Test.jsp' The final request string is '/TestApp/Test.jsp' If an exception occurs, it should also be logged in the proxy log file with the prefix:timestamp *******Exception type   WeblogicBridgeConfig DebugConfigInfo enables runtime statistics and the production of configuration information.  For security purposes, this parameter should be turned off in production. http://webserver_host:port/path/xyz.jsp?__WebLogicBridgeConfig will display a proxy bridge page detailing the plugin configuration followed by runtime statistics which could help in diagnosing issues along with the analyzing of the proxy log file.  In our example the url would be: http://localhost/wls/TestApp/Test.jsp?__WebLogicBridgeConfig  Here is how the top section of the screen can look like: The bottom part of the page contains runtime statistics, here is a snippet of it (unrelated with the previous JSP example).   This entire plugin configuration should be very similar with other web servers, what varies is the name of the proxy server configuration file. So, as you can see, it only takes a few minutes to configure a Weblogic cluster and get servers to join it.

  • Varnish, hide port number

    - by George Reith
    My set up is as follows: OS: CentOS 6.2 running on an OpenVZ virtual machine. Web server: Nginx listening on port 8080 Reverse proxy: Varnish listening on port 80 The problem is that Varnish redirects my requests to port 8080 and this appears in the address bar like so http://mysite.com:8080/directory/, causing relative links on the site to include the port number (8080) in the request and thus bypassing Varnish. The site is powered by WordPress. How do I allow Varnish to use Nginx as the backend on port 8080 without appending the port number to the address? Edit: Varnish is set up like so: I have told the Varnish daemon to listen to port 80 by default. VARNISH_VCL_CONF=/etc/varnish/default.vcl # # # Default address and port to bind to # # Blank address means all IPv4 and IPv6 interfaces, otherwise specify # # a host name, an IPv4 dotted quad, or an IPv6 address in brackets. # VARNISH_LISTEN_ADDRESS= VARNISH_LISTEN_PORT=80 # # # Telnet admin interface listen address and port VARNISH_ADMIN_LISTEN_ADDRESS=127.0.0.1 VARNISH_ADMIN_LISTEN_PORT=6082 # # # Shared secret file for admin interface VARNISH_SECRET_FILE=/etc/varnish/secret # # # The minimum number of worker threads to start VARNISH_MIN_THREADS=1 # # # The Maximum number of worker threads to start VARNISH_MAX_THREADS=1000 # # # Idle timeout for worker threads VARNISH_THREAD_TIMEOUT=120 # # # Cache file location VARNISH_STORAGE_FILE=/var/lib/varnish/varnish_storage.bin # # # Cache file size: in bytes, optionally using k / M / G / T suffix, # # or in percentage of available disk space using the % suffix.

  • Valid concerns over shared developer team

    - by alphadogg
    Say your company is committed (and don't want to consider not doing this) to sharing/pooling a development team across a handful of business units. What would you setup as concerns/expectations that must be cleared before doing this? For example: Need agreement between units on how much actual time (FTE) is allocated to each unit Need agreement on scheduling of staff need agreement on request procedure if extra time is required by one party etc... Have you been in a situation like this as a manager of one unit destined to use this? If so, what were problems you experienced? What would you have or did implement? Same if you were the manager of the shared team. Please assume, for discussion, that the people concerned know that you can swap devs in and out on a whim. I don't want to know the disadvantages of this approach; I know them. I want to anticipate issues and know how to mitigate the fallout.

  • Connect to running web role on Azure using Remote Desktop Connection and VS2012

    - by Magnus Karlsson
    We want to be able to collect IntelliTrace information from our running app and also use remote desktop to connect to the IIS and look around(probably debugging). 1. Create certificate 1.1 Right-click the cloud project (marked in red) and select “Configure remote desktop”. 1.2 In the drop down list of certificates, choose <create> at the bottom. 1.3. Follow the instructions, you can set it up with default values. 1.4 When done. Choose the certificate and click “Copy to File…” as seen in the left of the picture above. 1.5. Save the file with any name you want. Now we will save it to local storage to be able to import it to our solution through the azure configuration manager in step 3. 2. Save certificate to local storage Now we need to attach it to our local certificate storage to be able to reach it from our confiuguration manager in visual studio. Microsoft provides the following steps for doing this: http://support.microsoft.com/kb/232137 In order to view the Certificates store on the local computer, perform the following steps: Click Start, and then click Run. Type "MMC.EXE" (without the quotation marks) and click OK. Click Console in the new MMC you created, and then click Add/Remove Snap-in. In the new window, click Add. Highlight the Certificates snap-in, and then click Add. Choose the Computer option and click Next. Select Local Computer on the next screen, and then click OK. Click Close , and then click OK. You have now added the Certificates snap-in, which will allow you to work with any certificates in your computer's certificate store. You may want to save this MMC for later use. Now that you have access to the Certificates snap-in, you can import the server certificate into you computer's certificate store by following these steps: Open the Certificates (Local Computer) snap-in and navigate to Personal, and then Certificates. Note: Certificates may not be listed. If it is not, that is because there are no certificates installed. Right-click Certificates (or Personal if that option does not exist.) Choose All Tasks, and then click Import. When the wizard starts, click Next. Browse to the PFX file you created containing your server certificate and private key. Click Next. Enter the password you gave the PFX file when you created it. Be sure the Mark the key as exportable option is selected if you want to be able to export the key pair again from this computer. As an added security measure, you may want to leave this option unchecked to ensure that no one can make a backup of your private key. Click Next, and then choose the Certificate Store you want to save the certificate to. You should select Personal because it is a Web server certificate. If you included the certificates in the certification hierarchy, it will also be added to this store. Click Next. You should see a summary of screen showing what the wizard is about to do. If this information is correct, click Finish. You will now see the server certificate for your Web server in the list of Personal Certificates. It will be denoted by the common name of the server (found in the subject section of the certificate). Now that you have the certificate backup imported into the certificate store, you can enable Internet Information Services 5.0 to use that certificate (and the corresponding private key). To do this, perform the following steps: Open the Internet Services Manager (under Administrative Tools) and navigate to the Web site you want to enable secure communications (SSL/TLS) on. Right-click on the site and click Properties. You should now see the properties screen for the Web site. Click the Directory Security tab. Under the Secure Communications section, click Server Certificate. This will start the Web Site Certificate Wizard. Click Next. Choose the Assign an existing certificate option and click Next. You will now see a screen showing that contents of your computer's personal certificate store. Highlight your Web server certificate (denoted by the common name), and then click Next. You will now see a summary screen showing you all the details about the certificate you are installing. Be sure that this information is correct or you may have problems using SSL or TLS in HTTP communications. Click Next, and then click OK to exit the wizard. You should now have an SSL/TLS-enabled Web server. Be sure to protect your PFX files from any unwanted personnel. Image of a typical MMC.EXE with the certificates up.   3. Import the certificate to you visual studio project. 3.1 Now right click your equivalent to the MvcWebRole1 (as seen in the first picture under the red oval) and choose properties. 3.2 Choose Certificates. Right click the ellipsis to the right of the “thumbprint” and you should be able to select your newly created certificate here. After selecting it- save the file.   4. Upload the certificate to your Azure subscription. 4.1 Go to the azure management portal, click the services menu icon to the left and choose the service. Click Upload in the bottom menu.     5. Connect to server. Since I tried to use account settings(have to use another name) we have to set up a new name for the connection. No biggie. 5.1 Go to azure management portal, select your service and in the bottom menu, choose “REMOTE”. This will display the configuration for remote connection. It will actually change your ServiceConfiguration.cscfg file. After you change It here it might be good to choose download and replace the one in your project. Set a name that is not your windows azure account name and not Administrator. 5.2 Goto visual studio, click Server Explorer. Choose as selected in the picture below and click “COnnect using remote desktop”.   5.2 You will now be able to log in with the name and password set up in step 5.1. and voila! Windows server 2012, IIS and other nice stuff!   To do this one I’ve been using http://msdn.microsoft.com/en-us/library/windowsazure/ff683671.aspx where you can collect some of this information and additional one.

  • Interesting conversation about the nature of info-wars

    - by Malcolm Anderson
    Over at Schlock Mercenary, Howard Taylor has started a facinating conversation on the nature of Info-Wars. As Howard puts it:   Somebody (I forget who) tweeted that the Wikileaks fight right now is the first infowar in history. I disagree. I think we've fought numerous infowars in the last fifteen years. And that's really what I want to see discussed in the comments. We can argue right and wrong until the eCows come 127.0.0.1 but nobody is going to walk away convinced. I want to see a list of information-age conflicts that you feel qualify as "infowar." Me, I think the RIAA vs file-sharing qualifies. My buddy Rodney suggested RBLs vs Spammers (the spammers won that one.) Somebody pointed out that the Secret Service raid on Steve Jackson Games back in the 80's might qualify.

  • Diagram to show code responsibility

    - by Mike Samuel
    Does anyone know how to visually diagram the ways in which the flow of control in code passes between code produced by different groups and how that affects the amount of code that needs to be carefully written/reviewed/tested for system properties to hold? What I am trying to help people visualize are arguments of the form: For property P to hold, nd developers have to write application code, Ca, without certain kinds of errors, and nm maintainers have to make sure that the code continues to not have these kinds of errors over the project lifetime. We could reduce the error rate by educating nd developers and nm maintainers. For us to be confident that the property holds, ns specialists still need to test or check |Ca| lines of code and continue to test/check the changes by nm maintainers. Alternatively, we could be confident that P holds if all code paths that could violate P went through tool code, Ct, written by our specialists. In our case, test suites alone cannot give confidence that P holdsnd » nsnm ns|Ca| » |Ct| so writing and maintaining Ct is economical, frees up our developers to worry about other things, and reduces the ongoing education commitment by our specialists. or those conditions do not hold, so focusing on education and testing is preferable. Example 1 As a concrete example, suppose we want to ensure that our web-service only produces valid JSON output. Our web-service provides several query and mutation operators that can be composed in interesting ways. We could try to educate everyone who maintains those operations about the JSON syntax, the importance of conformance, and libraries available so that when they write to an output buffer, every possible sequence of appends results in syntactically valid JSON. Alternatively, we don't expose an output stream handle to application code, and instead expose a JSON sink so that every code path that writes a response is channeled through a JSON sink that is written and maintained by a specialist who knows JSON syntax and can use well-written libraries to produce only valid output. Example 2 We need to make sure that a service that receives a URL from an untrusted source and tries to fetch its content does not end up revealing sensitive files from the file-system, like file:///etc/passwd. If there is a single standard way that any developer familiar with the application language's libraries would use to fetch URLs, which has file-system access turned off by default, then simply educating developers about the standard mechanism, and testing that file probing fails for some inputs, will probably be sufficient.

  • Wordpress Installation (on IIS and SQL Server)

    - by Davide Mauri
    To proceed with the installation of Wordpress on SQL Server and IIS, first of all, you need to do the following steps Create a database on SQL Server that will be used by Wordpress Create login that can access to the just created database and put the user into ddladmin, db_datareader, db_datawriter roles Download and unpack Wordpress 3.3.2 (latest version as of 27 May 2012) zip file into a directory of your choice Download the wp-db-abstraction 1.1.4 (latest version as of 27 May 2012) plugin from wordpress.org website Now that the basic action has been done, you can start to setup and configure your Wordpress installation. Unpack and follow the instructions in the README.TXT file to install the Database Abstraction Layer. Mainly you have to: Upload wp-db-abstraction.php and the wp-db-abstraction directory to wp-content/mu-plugins.  This should be parallel to your regular plugins directory.  If the mu-plugins directory does not exist, you must create it. Put the db.php file from inside the wp-db-abstraction.php directory to wp-content/db.php Now you can create an application pool in IIS like the following one Create a website, using the above Application Pool, that points to the folder where you unpacked Wordpress files. Be sure to give the “Write” permission to the IIS account, as pointed out in this (old, but still quite valid) installation manual: http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#iis Now you’re ready to go. Point your browser to the configured website and the Wordpress installation screen will be there for you. When you’re requested to enter information to connect to MySQL database, simply skip that page, leaving the default values. If you have installed the Database Abstraction Layer, another database installation screen will appear after the one used by MySQL, and here you can enter the configuration information needed to connect to SQL Server. After having finished the installation steps, you should be able to access and navigate your wordpress site.  A final touch, and it’s done: just add the needed rewrite rules http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#urlrewrite and that’s it! Well. Not really. Unfortunately the current (as of 27 May 2012) version of the Database Abstraction Layer (1.1.4) has some bugs. Luckily they can be quickly fixed: Backslash Fix http://wordpress.org/support/topic/plugin-wp-db-abstraction-fix-problems-with-backslash-usage Select Top 0 Fix Make the change to the file “.\wp-content\mu-plugins\wp-db-abstraction\translations\sqlsrv\translations.php” suggested by “debettap”   http://sourceforge.net/tracker/?func=detail&aid=3485384&group_id=315685&atid=1328061 And now you have a 100% working Wordpress installation on SQL Server! Since I also wanted to take advantage of SQL Server Full Text Search, I’ve created a very simple wordpress plugin to setup full-text search and to use it as website search engine: http://wpfts.codeplex.com/ Enjoy!

  • External USB HD issues with a twist (works on Windows7 but not XP)

    - by Eruditass
    I have this older external USB HD, 160 GB. I was using it to copy my Steam games to another computer. On the source computer, Windows 7 64-bit, everything worked fine. Drive reported no errors, had no hiccups, etc. Plugging it into the Windows XP 32-bit computer, it worked fine for looking through the files, moving files around on it (no real reading/writing, just modifying the filesystem table). However, when copying files from it to my internal HD, after a couple seconds to tens of minutes (seemingly random times), the USB device becomes unrecognized and it reports a delayed write error. Events in system log go like this, chronologically: (number times displayed)xSource (Event ID): "message" 2xdisk (51): An error was detected on device \Device\Harddisk1\D during a paging operation. 1xftdisk (57): The system failed to flush data to the transaction log. Corruption may occur. 1xApplication popup (26): Windows - Delayed Write Failed : Windows was unable to save all the data for the file E:\$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. 1xntfs (50): {Delayed Write Failed} Windows was unable to save all the data for the file . 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. These repeat for a while, then there is 10+ disk messages or ftdisk messages. Other notes: This occurs on random files at random times. This problem cannot be replicated on the Windows 7 source machine when copying from the HD to a different location on its local disk chkdsk /f was run and found no errors. chkdsk /f/r has the delayed write issue. drive was set to quick removal. Setting to performance in device manager yielded same result I am not writing anything to the USB external drive, so I am not sure why there is even a delayed write error (writing file access times?) local Windows XP was chkdsk'd without problems Windows XP machine has no problems with other USB HD's Various USB ports were attempted Rebooting did not help Occurs with SyncToy as well as windows explorer SMART status is good on both local drive and the external one Lack of gaming is making me cranky

  • Access-based Enumeration (December 04, 2009)

    - by user12612012
    Access-based Enumeration (ABE) is another recent addition to the Solaris CIFS Service - delivered into snv_124.  Designed to be compatible with Windows ABE, which was introduced in Windows Server 2003 SP1, this feature filters directory content based on the user browsing the directory.  Each user can only see the files and directories to which they have access.  This can be useful to implement an out-of-sight, out-of-mind policy or simply to reduce the number of files presented to each user - to make it easier to find files in directories containing a large number of files. ABE is managed on a per share basis by a new boolean share property called, as you might imagine, abe, which is described insharemgr(1M).  When set to true, ABE filtering is enabled on the share and directory entries to which the user has no access will be omitted from directory listings returned to the client.  When set to false or not defined, ABE filtering will not be performed on the share.  The abe property is not defined by default.Administration is straightforward, for example: # zfs sharesmb=abe=true,name=jane tank/home/jane# sharemgr show -vp    zfs       zfs/tank/home/jane nfs=() smb=()          jane=/export/home/jane     smb=(abe="true") ABE is also supported via sharemgr(1M) and on smbautohome(4) shares. Note that even though a file is visible in a share, with ABE enabled, it doesn't automatically mean that the user will always be able to open the file.  If a user has read attribute access to a file ABE will show the it but access will be denied if this user tries to open the file for reading or writing. We considered supporting ABE on NFS shares, as suggested by the name of PSARC/2009/375, but we ran into problems due to NFS client readdir caching.  NFS clients maintain a common directory entry cache for all users, which not only defeats the intent of ABE but can lead to very confusing results.  If multiple users are looking at the content of a directory with ABE enabled, the entries that get cached will depend on who looks at the directory first.  Subsequent users may see files that ABE on the server would have filtered out or files may be missing because they were filtered out for the original user. Although this issue can be resolved by disabling the NFS client readdir cache, this was deemed to be an unsuitable solution because it would create a dependency between a server share property and the configuration on all NFS clients, and there was the potential for differences in behavior across the various NFS clients.  It just seemed to add unnecessary administration complexity so we pulled it out.

  • Using Movemail with Thunderbird on Ubuntu

    - by rxt
    I'm trying to read local mail with Thunderbird on Ubuntu (with both 12.04 and 13.04). I've followed the instructions found here: How can I access system mail in /var/mail/ via thunderbird? I can read mail on the system using alpine or vim, so I know the mailbox is not empty. When I click the get-mail button, nothing happens. I see no Inbox (or any folder structure) for the specific account. I've set the rights for /var/mail to 1777. Settings server name: localhost username: john How can I get this working? Okay, considering the extra bounty, I would like to get this working like normal mail. The accepted answer from Qasim resulted in a much more usable situation than before - opening mail in Thunderbird with layout. I still face three problems though. When new mail is received in the mailbox, Thunderbird won't see this until after I restart Thunderbird. When Thunderbird is restarted, all mail is reset to unread and deleted mail is undone. This is probably because Thunderbird reads the mail from the /var/mail/www-data file, but doesn't update this file. So after restarting, it simply reads this file again, with the new mail and all old mail. This is probably a postfix issue: mail is sent out to existing mail addresses, but cannot be delivered because the receiving mailserver cannot be reached. This results in "Undelivered mail returned to sender". Only one mailserver can be reached: localhost. Because this is a test system, I don't want real customers to receive mail. I've blocked mail ports in UFW to be sure. When opening the returned mail, I can scroll down and then I see the original mail with proper layout. So I can read the mail, see if the proper images are included, and for me that's workable. Having to restart TB to read new mail - I know when new mail arrives, so I know when to restart. Having old mail restored after a restart - not big problem as well. I can delete the mail file if it gets too much. I know how it works, but it would be nice if it worked like normal.

  • Blank desktop when logging in via xrdp

    - by nitefrog
    I am trying to access Ubuntu 11.10 using Remote Desktop from a Win 7 machine. I installed xrdp. I launch the Windows remote desktop client and login in. I then get prompted for the user name and password. It then logs in, but all I see is the background, no menus, nothing. I have to kill remote desktop by closing it. Even if I right click , nothing. Any ideas??? The only reason I even went down the RDP road was that VNC would not work either, even after I enabled desktop sharing. I am in a bind as I need to connect to Ubuntu via Windows. In version 8 Ubuntu this was not an issue and it just worked.
