• dpkg behaving strangely?

  When I use apt to get a package, I have been receiving the same error message. Here is an example trying to install wicd (which is already installed): Reading package lists...

• How to use call web service action in SharePoint2013 workflow

  - by ybbest

  In SharePoint2013, you can use call web service action and loop. In this post, I will show you how to achieve this. 1. Create a List workflow called CallWebService 2. Create a variable called listurl and assign the value to http://sp2010/_vti_bin/listdata.svc 3. Create a dictionary variable called RequestHeaders and add the following key value pairs. 4. Call the web service with the HttpHeaders you just build in the previous step and store the response in the variable ResponseContent. 5. The ResponseContent variable is the Dynamic values (in SharePoint designer it will be called dictionary type) and it is new feature for SharePoint2013 workflow. We can use the following actions to count the number items in the variable. 6. You can use loop in SharePoint 2013 workflow and out each list title as shown below.

• Nagios3 gives a warning on HTTP service monitoring

  - by Dez

  Already set up my local net configuration to be monitored by Nagios3. I found a problem that Nagios3 reports a warning in the HTTP monitoring service of a Debian server set at ip 192.168.1.52, that has an individual virtual host and a mass virtual host for application development. I get this status message: HTTP WARNING: HTTP/1.1 404 Not Found I used the Nagios tools to check. servername is the name of the vhost server name I used in the Apache configuration. /usr/lib/nagios/plugins/check_http -H servername -I 192.168.1.52 receiving this status message: HTTP OK HTTP/1.1 200 OK - 37900 bytes in 0.504 seconds |time=0.503946s;;;0.000000 size=37900B;;;0 But when I check like this: /usr/lib/nagios/plugins/check_http -I 192.168.1.52 I get the same status message as the warning, so I assume that I don't have Nagios completely well set up because doesn't recognize the vhosts for that server, how it should be as the check_http service shows. Where should I look to fix that warning?

• Getting codebaseHQ SVN ChangeLog data in your application

  - by saifkhan

  I deploy apps via ClickOnce. After each deployment we have to review the changes made and send out an email to the users with the changes. What I decided now to do is to use CodebaseHQ’s API to access a project’s SVN repository and display the commit notes so some users who download new updates can check what was changed or updated in an app. This saves a heck of a lot of time, especially when your apps are in beta and you are making several changes daily based on feedback. You can read up on their API here Here is a sample on how to access the Repositories API from a windows app Public Sub GetLog() If String.IsNullOrEmpty(_url) Then Exit Sub Dim answer As String = String.Empty Dim myReq As HttpWebRequest = WebRequest.Create(_url) With myReq .Headers.Add("Authorization", String.Format("Basic {0}", Convert.ToBase64String(Encoding.ASCII.GetBytes("username:password")))) .ContentType = "application/xml" .Accept = "application/xml" .Method = "POST" End With Try Using response As HttpWebResponse = myReq.GetResponse() Using sr As New System.IO.StreamReader(response.GetResponseStream()) answer = sr.ReadToEnd() Dim doc As XDocument = XDocument.Parse(answer) Dim commits = From commit In doc.Descendants("commit") _ Select Message = commit.Element("message").Value, _ AuthorName = commit.Element("author-name").Value, _ AuthoredDate = DateTime.Parse(commit.Element("authored-at").Value).Date grdLogData.BeginUpdate() grdLogData.DataSource = commits.ToList() grdLogData.EndUpdate() End Using End Using Catch ex As Exception MsgBox(ex.Message) End Try End Sub

• Stable MSN messenger for mac?

  - by Console

  I use Adium in my mac as a client for MSN messenger. (I have also tried the "official" live messenger for mac for a while but it had even worse issues than what I am experiencing with Adium). Everything works fine for the first 5-10 minutes, perhaps until the first automatic "away", then suddenly any message I send is followed by a dozen or so messages saying: "Message could not be sent because a connection error occurred:" and Message may have not been sent because a timeout occurred: If I send a few messages, they usually eventually arrive (all at once) after a long delay. Windows machines on the same network running live messenger work fine. Any ideas why this might be, or suggestions for a client that might work when both Adium and Microsofts own messenger for mac seem to disconnect?

• Delete file then run file at startup

  - by Henry Gibson

  I'm running the music player Foobar2000 through Wine at startup. For some reason when I shutdown Ubuntu the Foobar2000 process is ended abnormally in Wine and when it runs next time I get an annoying "start in safe mode?" message. Not a huge problem, but I'd like it fixed. The safe mode message only appears if a file called "running" is present when Foobar2000 starts (if it isn't deleted when closed properly). So by deleting "running" then starting Foobar2000, the message doesn't appear. I thought it would be easy enough to enter this as a startup command, however it doesn't want to work. The command I am using is rm '/home/henry/.wine/drive_c/users/henry/Application Data/foobar2000/running';'/home/henry/.wine/drive_c/Program Files (x86)/foobar2000/foobar2000.exe' which works fine if I just run it from terminal, the file is deleted then foobar2000 runs. Does anyone know why this isn't working at startup? Also, will this run with a terminal visible? How can I make just the gui appear? Thanks

• WICD Network Manager does'nt work in 13.10

  - by Jayakumar J

  I am currently making use of a Wired Broadband, where in the default Network Manager though shows that the Auto Ethernet is connected, I was unable to browse through any websites in the browser. I had to disconnect & connect the Auto Ethernet several times in the Network Manager or restart Ubuntu to get it fixed. But following these steps is quiet annoying as this issue happens very frequently. I browsed through the internet and got to know that WICD Network Manager fixes this issue. Earlier I have been using Ubuntu 12.04 where the same issue was fixed by making use of WCID Network Manager. Recently I upgraded to 13.10 and as I got the same network issue in default Network Manager, I have installed WICD Network Manager but when I try to open WCID, I get an alert message saying, "Could not connect to wicd's D-Bus interface. Check the wicd log for error messages." When I click on OK, I get the same message again and when I click on OK again I get the following message, "Error connecting to wicd service via D-Bus.Please ensure the wicd service is running." Any help to fix this issue is greatly appreciated as this issue was annoying me since I installed 13.10

• NetworkManager broken after upgrade to Kubuntu Saucy

  - by queueoverflow

  I had Kubuntu 13.04 on my ThinkPad X220, and I upgraded to 13.10 and I am not able to connect to a wired or wireless connection. The new network tray icon does not show any entries at all. In the menu of the tray icon, there is an error saying: Require NetworkManager 0.9.8, found . I then tried the following: nmcli con ** (process:3695): WARNING **: Could not initialize NMClient /org/freedesktop/NetworkManager: Rejected send message, 3 matched rules; type="method_call", sender=":1.64" (uid=1000 pid=3695 comm="nmcli con ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination="org.freedesktop.NetworkManager" (uid=0 pid=1116 comm="NetworkManager ") Error: nmcli (0.9.8.0) and NetworkManager (unknown) versions don't match.

How can I get networking back to work without a reinstall?

• Original sender is not correctly identified when spam is forwarded

  - by Stephan Burlot

  I have a forwarding rule with Postfix that forwards all messages to my main email address. When a spam message is sent to one of my emails, it is forwarded but the sender is shown as being the forwarding domain, not the spammer's domain. Real example: mywebsite.com is hosted on Linode. [email protected] sends an email to [email protected] the mail is forwarded to [email protected] my email hosting (anotherwebsite.com) sees it's spam and sends a message to [email protected] and Linode reports a TOS violation. I have modified my postfix settings so I now use RBL, but if a message goes through, it may happen again. How can I prevent this to happen again? Is there some settings to change on Postfix so the original sender is correctly identified? Thanks Stephan EDIT: The steps I did to prevent this to happen again are: Add RBL checking to Postfix Add postgrey to Postfix And finally fix the MX record which was incorrect. I checked with a test email on Spamcop.net and the original sender is correctly identified.

• Design Application to "Actively" Invite Users (pretend they have privileges)

  - by user3086451

  I am designing an application where users message one another privately, and may send messages to any Entity in the database (an Entity may not have a user account yet, it is a professional database). I am not sure how to best design the database and the API to allow messaging unregistered users. The application should remain secure, and data only accessed by those with correct permissions. Messages sent to persons without user accounts serve as an invitation. The invited person should be able to view the message, act on it, and complete the user registration upon receiving an InviteMessage. In simple terms, I have: User misc user fields (email, pw, dateJoined) Entity (large professional dataset): personalDetails... user->User (may be null) UserMessage: sender->User recipient->User dateCreated messageContent, other fields..... InviteMessage: sender->User recipient->Entity expiringUrl inviteeEmail inviteePhone I plan to alert the user when selecting a recipient that is not registered yet, and inform that he may send the message as an invitation by providing email, phone where we can send the invitation. Invitations will have a unique, one-time-use URL, e.g. uuid.uuid4(). When accessed, the invitee will see the InviteMessage and details about completing his/her registration profile. When registration is complete, InviteMessage details to a new instance of UserMessage (to not lose their data), and assign it to the newly created User. The ability to interact with and invite persons who do not yet have accounts is a key feature of the application, and it seems better to separate the invitation from the private, app messages (easier to keep functionality separate, better if data model changes). Is this a reasonable, good design? If not, what would you suggest? Do you have any improvements? Am I correct to choose to create a separate endpoint for creating invitations via the API?

• rEFIt can't sync GPT and MBR after resizing boot camp partition

  - by benwad

  I've been trying to follow the instructions here to increase the size of my boot camp partition: http://plonsdale.wordpress.com/2011/06/24/tech-tip-increasing-the-size-of-a-bootcamp-partition-with-free-tools/ I got as far as step 3 when I booted from the rEFIt CD. I selected the partitioning tool and it gave me the following message: Error: Not Found returned from gptsync.efi Now the Windows boot camp partition doesn't show up when I hold alt when starting my mac. Trying to boot into Windows using the rEFIt CD gives me a message saying no Windows installation is found. I then booted off the Windows 7 install CD and the 'repair' option gave me this message: This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows ...and if I try and go install a fresh version of Windows on this partition using the 'Custom (advanced)' option I get an error about the partition saying: Windows cannot be installed to this disk. The selected disk is of the GPT partition style

• What does 'http: getaddrinfo*.gaih_getanswer: got type "46"' mean

  - by koffie

  Today I got an e-mail from logcheck informing me that the following system event occurred. http: getaddrinfo*.gaih_getanswer: got type "46" Indeed, the above message occurs 4 times in /var/log/aut.log it occured twice yesterday around 6:46 am. And this morning it also occured twice around the same time. I wonder what this message means and if this message is something to worry about or if should just tell logcheck to ignore it. If it is something to worry about, then any pointers on how to fix the problem are appreciated.

• Nautilus crashes after Ubuntu Tweak Package Cleaner

  - by Ka7anax

  Few days ago I started having some problems with nautilus. Basically when I'm trying to get into a folder it crashes. It's not happening all the time, but in 85% it does... Sometimes, after the crash all my desktop icons are also gone. The only thing that I think causes this is Ubuntu Tweak - I'm not sure, but the issues started after I did the Package cleaner from Ubuntu Tweaks... Any ideas? -------- EDIT ---------- First time, after running the command (nautilus --quit; nautilus --no-desktop) 3 times all the system crashed (except the mouse, I could move the mouse). After restart I run it and obtain this: ----- Initializing nautilus-gdu extension Initializing nautilus-dropbox 0.6.7 (nautilus:2966): GConf-CRITICAL **: gconf_value_free: assertion value != NULL' failed (nautilus:2966): GConf-CRITICAL **: gconf_value_free: assertionvalue != NULL' failed Nautilus-Share-Message: Called "net usershare info" but it failed: 'net usershare' returned error 255: net usershare: cannot open usershare directory /var/lib/samba/usershares.

• How to store character moves (sprite animations)?

  - by Saad

  So I'm thinking about making a small rpg, mainly to test out different design patterns I've been learning about. But the one question that I'm not too sure on how to approach is how to store an array of character moves in the best way possible. So let's say I have arrays of different sprites. This is how I'm thinking about implementing it: array attack = new array (10); array attack2 = new array(5); (loop) //blit some image attack.push(imageInstance); (end loop) Now every time I want the animation I call on attack or attack2; is there a better structure? The problem with this is let's say there are 100 different attacks, and a player can have up to 10 attacks equipped. So how do I tell which attack the user has; should I use a hash map?

• Why is Mac OS X 10.6 using /usr/lib to start Apache when I compiled PHP using /opt/local/lib?

  - by Anthony

  PHP 5.3.3 compiled on Mac OS X 10.6 - using /usr/lib when trying to start Apache... rather than /opt/local/lib specified when PHP was configured. Why is it trying to load from /usr/lib when I specified in my configure not to? httpd: Syntax error on line 115 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec/apache2/libphp5.so into server: dlopen(/usr/libexec/apache2/libphp5.so, 10): Library not loaded: /opt/local/lib/libiconv.2.dylib\n Referenced from: /usr/libexec/apache2/libphp5.so\n Reason: Incompatible library version: libphp5.so requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 The error message above refers to /opt/local/lib which when I run: otool -LD /opt/local/lib/libiconv.2.dylib Message: /opt/local/lib/libiconv.2.dylib: /opt/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.0) It shows that the version is different than what httpd is erring out as. I have a feeling I need to recompile Apache using newer libraries, but the error message still doesn't make too much sense to me.

• Distributed transactions and queues, ruby, erlang

  - by chrispanda

  I have a problem that involves several machines, message queues, and transactions. So for example a user clicks on a web page, the click sends a message to another machine which adds a payment to the user's account. There may be many thousands of clicks per second. All aspects of the transaction should be fault tolerant. I've never had to deal with anything like this before, but a bit of reading suggests this is a well known problem. So to my questions. Am I correct in assuming that secure way of doing this is with a two phase commit, but the protocol is blocking and so I won't get the required performance? It appears that DBs like redis and message queuing system like Rescue, RabbitMQ etc don't really help me a lot - even if I implement some sort of two phase commit, the data will be lost if redis crashes because it is essentially memory-only. All of this has led me to look at erlang - but before I wade in and start learning a new language, I would really like to understand better if this is worth the effort. Specifically, am I right in thinking that because of its parallel processing capabilities, erlang is a better choice for implementing a blocking protocol like two phase commit, or am I confused?

• Writing my first bash script (line 2: testscript: No such file or directory)

  - by skyeagle

  I am attempting to write my first shell script (I'm running Ubuntu 10.x) This is what my 'script' looks like cd /path/to/directory/cronscripts . testscript I put the following debug statements (after the cd), in the script above to make sure everything was ok: pwd echo `ls -lhrt` and it displayed all the files in the directory. So I dont understand the error message I am getting. I have the following two questions Why am I getting the above error message and how do I fix it? My script seems to run fine without a shebang in the first line - infact when I try either of the following: #!/usr/bin/bash #!/usr/bin/bash env I get the following error message: /usr/bin/bash: bad interpreter: No such file or directory What is the purpose of the shebang statement and why do I get the above error when I try to include it in my script/ how do I fix it, so I can add the shebang (is it necessary? - it seems most script examples have the shebang - but I'm not sure if it is a must, as the script runs without it).

• How do I add xen kernel boot parameters in grub2?

  - by Matt

  I know that I can add command line parameters to the grub2 command line by editing /etc/default/grub according to this answer How do I add a boot parameter to grub2 in Ubuntu 10.10? However, that would apply to ALL kernels would it not? How do I apply the command line parameters to specific kernels? i.e. only xen.

• Bad DMA/do_IRQ errors on suspend/resume, with occasional freezing

  - by Steve Kroon

  Every time I suspend or resume my laptop (Dell Latitude E6520, bought this year), I get 2 messages of the form displayed on the console just before shutting down/starting up: [ 407.107610] ehci_hcd 0000:00:1d.0: dma_pool_free buffer-128, f6f18000/36f18000 (bad dma) On occasion, I get a message of the form: [ 3753.979066] do_IRQ: 0.177 No irq handler for vector (irq -1) On occasion, my machine freezes with a flashing Caps Lock button when suspending, after which I need to do a hard shutdown. This never happened before the messages started appearing (a while back), and I think it never happens without a do_IRQ message appearing (although I'm not sure about that). [There's nothing in the owner's manual on a flashing Caps Lock button; apparently it may be a kernel panic if the scroll lock also flashes, but the laptop doesn't have a scroll lock light, and there's no message on the console saying kernel panic.] Are these bad DMA/do IRQ messages serious, and what can I do to investigate/troubleshoot them and the freezing? Edit: I've also now received the following error messages a few times: [246943.023908] JBD: I/O error detected when updating journal superblock for sdb1. [246943.023958] Buffer I/O error on device sdb1, logical block 0 [246943.023996] EXT3-fs (sdb1): I/O error while writing superblock Edit: Output of dmesg at http://pastebin.com/ra7MTQEj ; contents of /var/log/kern.log at http://pastebin.com/i6jf0Md9 Edit: the output of some smartctl (-a, -x, --log=error, --log=xerror) instructions is available at http://paste.ubuntu.com/1088488/ . Edit (31/8/2012): Output of dmesg|grep -i ehci available at http://paste.ubuntu.com/1177246/ .

• Original sender is not correctly identified when spam is forwarded

  - by Stephan Burlot

  I have a forwarding rule with Postfix that forwards all messages to my main email address. When a spam message is sent to one of my emails, it is forwarded but the sender is shown as being the forwarding domain, not the spammer's domain. Real example: mywebsite.com is hosted on Linode. [email protected] sends an email to [email protected] the mail is forwarded to [email protected] my email hosting (anotherwebsite.com) sees it's spam and sends a message to [email protected] and Linode reports a TOS violation. I have modified my postfix settings so I now use RBL, but if a message goes through, it may happen again. How can I prevent this to happen again? Is there some settings to change on Postfix so the original sender is correctly identified? Thanks Stephan

  Backup (Deja Dup) failed to do an initial backup to my Amazon S3, and despite my best Googling efforts, I could not find a solution : ( Here's the error message: BackendException: Error uploading s3+http://deja-dup-auto-akiaiksyiqi3buaaz26a/My-Archive/duplicity-full.20130805T143807Z.vol1.difftar.gpg I'm running Ubuntu 12.04 LTS on a System76.

• How to avoid maximum Workgroup Manager connections in Mac OS X Server 10.6

  - by Stephan

  Is there a limit on the Mac OS X Server (10.6) Workgroup Manager in respect to concurrent connections to a server? I have an OS X server up and running and Open Directory configured but I am not able to log in remotely as I get the message the maximum number of connections for Workgroup Manager is already reached and I should wait for a user to disconnect. Even after a restart I get this message remotely. However, locally on the server I can start Workgroup Manager without any issues. It always lets me connect. Any advice what I need to do to make Workgroup Manager work from a remote location? I could not find any max connection setting in Server-Admin and nothing in the slapd log files. The server license says unlimited so I am quite sure it should not be a regular error message that indicates to me I should upgrade.
