  • Windows Server 2008 R2 DFSR Backlog Troubleshooting - Where to look for the cause of the problem?

    - by caleban
    Our target server indicates it has hundreds of thousands of backlogged transactions. Our authoritative source server indicates it has no backlogged transactions. No replication is taking place. Tests with plain text files aren't replicating. dfsdiag propogation tests fail to propogate. I've restarted the DFS services. I've restarted the servers. I've created new DFS shares to test with. The authoritative source server indicates it has no backlogs and the target indicates it has backlogs (which are the files it's waiting to receive). Files don't replicate in either direction. 2x Windows Server 2008 R2 Standard servers One server is at each of two sites The DFSR shares are on each respective server \site_1_server_1\users \site_2_server_1\users The sites are connected by a T1 DFSR worked for a week. I added a new share, another folder on the same servers, and that replicated for a weekend but never finished. Then all replication stopped. Is Windows DFSR flaky? What tools should I use and what should I look at to identify what's causing this problem?

  • How to remove strict RSA key checking in SSH and what's the problem here?

    - by setatakahashi
    I have a Linux server that whenever I connect it shows me the message that changed the SSH host key: $ ssh root@host1 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 93:a2:1b:1c:5f:3e:68:47:bf:79:56:52:f0:ec:03:6b. Please contact your system administrator. Add correct host key in /home/emerson/.ssh/known_hosts to get rid of this message. Offending key in /home/emerson/.ssh/known_hosts:377 RSA host key for host1 has changed and you have requested strict checking. Host key verification failed. It keeps me for a very few seconds logged in and then it closes the connection. host1:~/.ssh # Read from remote host host1: Connection reset by peer Connection to host1 closed. Does anyone know what's happening and what I could do to solve this problem?

  • How do I fix libdispatch problem crashing Mac OS X apps?

    - by david-ocallaghan
    In the last day I have started having a lot of brokenness on my Mac (MacBook Air running Mac OS X 10.6.2 with all software updates). Most noticably, iTunes no longer syncs with my iPhone. It fails with a crash dialog reporting "AppleMobileDeviceHelper quit unexpectedly" and an error dialog "iTunes was unable to load dataclass information from SyncServices. Reconnect or try again later." I've attempted the fix at support.apple.com/kb/HT1747 but it failed. I've also been having problems (at first seemingly unrelated) with the horrible Cisco VPN client, which started giving me this error: Error 51: Unable to communicate with the VPN subsystem I followed the steps at www.anders.com/cms/192/CiscoVPN/Error.51:.Unable.to.communicate.with.the.VPN.subsystem which don't seem to work for me, although I can connect if I use the command line with sudo : sudo vpnclient connect MyProfile I had a look in the Console app at the diagnostic messages and I noticed a pattern, that a number of apps were reporting "BUG IN CLIENT OF LIBDISPATCH". The affected programs are: AppleMobileBackup AppleMobileDeviceHelper Safari Webpage Preview Fetcher cvpnd (the Cisco VPN daemon) Of these, only the last is non-Apple software! The common text in the diagnostic messages is: Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Crashed Thread: 1 Dispatch queue: com.apple.libdispatch-manager Application Specific Information: BUG IN CLIENT OF LIBDISPATCH: Do not close random Unix descriptors I'm beginning to wonder if there's a permissions problem, or corruption of an important library, ... I should note that I've rebooted several times and verified the disk permissions and the disk. Any help would be great!

  • odd problem with jni interacting with dll's - not sure why a change to gc ergonomics fixes it

    - by jim hale
    We were having a problem with our Tomcat jvm blowing up and giving us an hs_* dump at random times but always in the same spot, that wasn't very informative other than saying we had an EXCEPTION_ACCESS_VIOLATION Commenting out various parts of the java that called particular jni functions just made it blow consistently in another spot. By changing our jvm options from: set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+UseParallelGC -XX:+UseParallelOldGC -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote TO set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote The problem went away. The solution does not give me a warm and fuzzy however and am wondering anyone might understand what's going on under the covers here. Environment: jdk1.6, 64 bit OS and Java, Tomcat, Windows

  • Task Scheduler Crashing MMC

    - by Valrok
    I've been getting errors whenever I try to run the task scheduler for Windows 2008 R2. Each time that I've tried running it, the task scheduler will crash and report the following: Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: mmc.exe Problem Signature 02: 6.1.7600.16385 Problem Signature 03: 4a5bc808 Problem Signature 04: System.Windows.Forms Problem Signature 05: 2.0.0.0 Problem Signature 06: 50c29e85 Problem Signature 07: 151f Problem Signature 08: 18 Problem Signature 09: Exception OS Version: 6.1.7601.2.1.0.16.7 Locale ID: 1033 I've been looking online but so far I keep finding mixed results on what could be the fix for this and was wondering if anyone here has ever ran into this issue before. I read that this issue could be because of Security Update for Microsoft Windows (KB2449742) and that by uninstalling it I would be able to fix this issue, however I was not able to locate this anywhere in the server. Here's the link if interested Patch wise, everything is up to date. Also, I tried running hotfix KB2688730 to see if that would work after doing some research online, however the hotfix is not applicable to the computer. If anyone could provide some information on how to fix this and get the task scheduler running again it would be extremely helpful!

  • WTH? Upgrading Ubuntu 9.10 to 10.04 Problem: No Internet Connection?

    - by damx
    Earlier today I tried upgrading my Ubuntu 9.10 Karmic Kaola from the update manager. (FYI: all 9.10 updates were applied prior to this) Everything was going well downloading until I got an error dialog informing me that some software packages weren't downloaded because of an Internet connection. Would say it was halfway thru. Anyway, Was told that the software packages that it did download, however, would kept and I figure it's not a big deal. Just run it again. But first ran Firefox to verify my connection as I haven't had any connection problems. But my internet connection was/is fine as evident by this posting. With that cleared, I ran the update manager again, clicked on "Upgrade" and this time I received "Could not download the release notes. Please check your internet connection" huh? This is my first time dealing w/ Ubuntu and my first upgrade so I am hoping someone can help. Not sure what the problem can be. I am can surf the web w/ no problems. Please help. PS: There was no installing at any point. Just downloading. PSS: The software it managed to download the first time around is now visible in the update manager but don't think I should install as I see in the compiz description it's for v1:0.8-4-0ubuntu2 I figure it's designed for 10.04 and might ruin things further if I install

  • Site to Site VPN problem, connection succesful data only oneway?

    - by Charles
    To start things off, I'm not the actual Administrator for the VPN Server, but he is also at a loss so I thought I'd ask it here. I know it's a Cisco ASA Firewall/VPN. I have a router that connects to the Cisco VPN server, it does so succesfully. I can ping everything within the remote network and from the remote network into my own. I've been able to SSH into a remote server over VPN as well, it all seems to work; until there's some more data returned. A quick example would be an internal webserver. The default homepage simply redirects, so only sends back HTTP headers with a "Location:". I receive this on my computer, but when I request the actual page then (which isn't that big) I don't get a response at all - it just stalls. And it does this for other services as well, for example SSH. I can do a couple of things while connected, but if there's more than xx output it seems to do nothing. The connection remains active throughout all of this. Has anyone ever experienced anything like this before / know what the problem might be? Another user who has a site-to-site connection with this VPN using the -exact same setup- has no problems, the only difference is that I have around 200ms ping to the VPN server/network because of a very long distance (other continent).

  • Problem in Setting image in imageview inside ListView in Android?

    - by sunil
    Hi, I have a listview which includes 2 textviews and 1 imageview. Now, the image in imageview will be set on certain conditions otherwise it should be left blank with no image. The problem is the images are not coming in proper rows. Say, for eg the image should be displayed at row 3 but its displayed at row 4. And, in some cases each row will have the same image. Has someone faced this kind of an issue? I am really clueless about the reason behind this. Can anyone point out the problem? Regards Sunil

  • Flex Client application - HTTPRequest problem in the initialize function.

    - by Elad
    Hello all. I have a serious problem in my flex client applications. I have an apache server with php web services. the flex client makes an httpservice requests. I noticed that the httpservice requests that runs from the creationComplete event of the application does not always get data from the server. but HTTPservice requests called from user actions always work. I also noticed that when I run the flex client application directly from the Flex Builder 3 without upload it to the server, the problem occours less frequently. in the Application: mx:Application creationComplete="Init()" verticalScrollPolicy="off" horizontalScrollPolicy="off" xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#5d8eb1" private function Init():void { var http_request:HTTPService = new HTTPService(); http_request.url = "http://"+this.server_name+":"+this.server_port+"/services/client/client_result.php"; http_request.resultFormat = "e4x"; http_request.addEventListener("result",resultFunc); http_request.send(); http_request.disconnect(); }

  • Ajax problem not displaying data using multiple javascript calls...

    - by Ronedog
    I'm writing an app that uses ajax to retrieve data from a mysql db using php. Because of the nature of the app, the user clicks an href link that has an "onclick" event used to call the javascript/ajax. I'm retrieving the data from mysql, then calling a separate php function which creates a small html table with the necessary data in it. The new table gets passed back to the responseText and is displayed inside a div tag. The tables only have around 10-20 rows of data in them. This functionality is working fine and displays the data in html form exactly as it needs to be on the page. The problem is this. the HREF "onclick" event needs to run multiple scripts one right after the other. The first script updates the "existing" data and inside the "update_existing" function is a call to refresh a section of the page with the updated HTML from the responseText. Then when that is done a "display_html" function is called which also updates a different section of the page with it's newly created HTML table. The event looks like this: Update This string gets built dynamically using php with parameters supplied, but for this example I simply took the parameters out so it didn't get confusing. The "update_existion() function actually calls the display_html() function which updates a section of the page as needed. I need to update a different section of the page on the same click of the mouse right after the update, which is why I'm calling the display_html() again, right after it. The problem is only the last call is being updated on my screen. In other words, the 2nd function call "display_html()" executes and displays the refreshed data just fine, but the previous call to update_existing() runs and updates the database properly, but doesn't display on the screen unless I press the browsers "refresh" button, which of course displays the new data exactly how I want it to, but I don't want the users to have to press the "refresh" button. I tried adding multiple "display_html() calls one right after the other, separating all of them with the semicolon and learned that only the very last function call actually refreshed the div element on the html page with the table information, although all the previous display_html() calls worked, they couldn't be seen on the page without a refresh of the browser. Is this a problem with javascript, or the ajax call, or is this a limitation in the DOM that only allows one element to be updated at a time. The ajax call is asynchroneous, but I've tried both, only async works period. This is the same in both Firefox and Internet Explorer Any ideas what's going on and how to get around it so I can run these multiple scripts?

  • LiveView plugin template creates lots of errors?

  • Windows 7 x64 wired connection problem. IP, gateway, dns assigned, can't ping. Network detected as "Network"

    - by Emil Lerch
    I am having a problem connecting to a specific wired network with my Latitude E6410 laptop. Other wired networks seem to work fine, but this one does not. I have a coworker with me with the same Intel 82577LM Gigabit Network card, and he can connect just fine. I've updated to the latest Intel drivers (11.8.75.0) and am not using Pro Set. I obtain all DHCP information just fine (IP, netmask, DNS server, default gateway). I cannot ping anything (internal or on the Internet - I tried pinging Google's public DNS servers by IP 8.8.8.8), nor can I get answers to any DNS queries through NS Lookup. Windows troubleshooting says everything is fine, but I can't get DNS responses. I've seen issues like this in the past that were related to link speed/duplex autonegotiaion failures, so I've tried manually setting link speed/duplex to all values one by one with no success. My coworker is using all default settings, so he is just using autonegotiate. Any ideas of other things to try?

  • jqGrid local date manipulation; problem with row ids when deleting and adding new rows

    - by Sam
    I'm using jqGrid as a client side grid input, allowing the user to input multiple records before POSTing all the data back at once. I'm having a problem where if the user has added a few records (say 3 ) the id's for the records will be 1,2,3. if the user deletes record 2, you're left with 1 and 3 for the id of the records. When the user now adds a new records, jqGrid assigns that records the id 3 again since it just seems to count the total records and increments it by one for the new record. This causes problems when selecting rows as now the row id's are 1, 3 and 3. Does anyone know how to access the row ids of records as I could probably use the afterSubmit event and reassign the row id's increasing from 1. ( so after i delete row id 2, this will set the other row id's to 1 and 2) Any other suggestions to solve this problem? Thanks

  • Whats the problem with int *p; *p=23;

    - by piemesons
    Yesterday in my interview I was asked this question. (At that time I was highly pressurized by so many abrupt questions). int *p; *p=23; printf('%d',*p); Is there any problem with this code? I explained him that you are trying to assign value to a pointer to whom memory is not allocated. But the way he reacted, it was like I am wrong. Although I got the job but after that he said Mohit think about this question again. I don't know what he was trying to say. Please let me know is there any problem in my answer?

  • Sony PMB causing failure to load Windows 7 Pro 64-bit normally or even Safe Mode

    - by Wesley
    After installing Sony's Picture Motion Browser on my desktop with Windows 7 Pro x64, it always goes to Startup Repair due to Windows 7 failing to start. This always happens after I try to install it. I've installed with all unnecessary programs closed and all disk drives and unnecessary usb ports empty. I don't exactly know what is causing the problem. Any ideas? My desktop is an HP m8530f. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01469325&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=3740333&lang=en Only upgrades are an HD4350 and a 500W PSU.

  • jQuery: Counter, Tricky problem with effects for brainy people.

    - by Marius
    Hello there! I made this counter that I think is cool because it only makes visible changes to the numbers being changed between each time it is triggered. This is the code // counter $('a').click(function(){ var u = ''; var newStr = ''; $('.counter').each(function(){ var len = $(this).children('span').length; $(this).children('span').each(function(){ u = u + $(this).text(); }); v = parseInt(u) + 1; v = v + ''; for (i=v.length - 1; i >= 0; i--) { if (v.charAt(i) == u.charAt(i)) { break; } } slce = len - (v.length - (i + 1)) updates = $(this).children('span').slice(slce); $(updates).fadeTo(100,0).delay(100).each(function(index){ f = i + 1 + index; $(this).text(v.charAt(f)); }).fadeTo(100,1); }); }); Markup: <span class="counter"> <span></span><span></span><span></span><span></span><span></span><span></span><span style="margin-right:4px;">9</span><span>9</span><span>9</span><span>9</span> </span> <a href="">Add + 1</a> The problem is that I previously used queue() function to delay() $(this).text(v.charAt(f)); by 100ms, (without queue the text()-function would not be delayed because it isnt in the fx catergory) so that the text would be updated before the object had faded to opacity = 0. That would look stupid. When adding multiple counters, only one of the counters would count. When removing the queue function, both counters would work, but as you can imagine, the delay of the text() would be gone (as it isnt fx-category). It is probably a bit tricky to make out how I can have multiple counters, and still delay the text()-function by 100ms, but I was hoping there is somebody here with spare brain capacity for these things ;) You can see a (NSFW) problem demo here: Just look underneath the sharing icons and you will notice that the text changes WHILE the objects fade out. Looking for some help to sove this problem. I would like to call the text() function once the text has faded to opacity 0, then fade in once the text() has executed. Thank you for your time.

  • Problem in databinding a dictionary in ListView combo-box column.

    - by Ashish Ashu
    I have a listview of which itemsource is set to my custom collection, let's say MyCollection. The code below is not full code , it's just a code snippets to explain the problem. class Item : INotifyPropertyChanged { Options _options; public Options OptionProp { get { return _options; } set { _options = value; OnPropertyChanged ("OptionProp");} } string _Name; public string NameProp { get { return _Name; } set { _Name = value; OnPropertyChanged ("NameProp");} } } class Options : Dictionary<string,string> { public Options() { this.Clear(); this.Add("One" , "1" ); this.Add("Two" , "2" ); this.Add("Three" , "3" ); } } MyCollection in my viewModel class viewModel { ObservableCollection<Item> **MyCollection**; KeyValuePair<sting,string> **SelectedOption**; } The listview Item Source is set to my MyCollection. <ListView ItemSource = MyCollectoin> I Listview contains two columns of which I have defined a datatemplats in the listview. First column is a combo-box of which Itemsource is set to Options ( defined above ) Second column is a simple textblock to display Name. Problem 1. I have defined a datatemplate for first column in which I have a combo box , I have set the Itemsource =**MyCollection** and SelectedItem = SelectedOption of the combo-box.

However the combo box contains options One, Two and Three. Also, I have initialized the SelectedOption to contain the first item, i:e One. problem 2. . Let suppose, I have added a single row in a listview and I have selected Option "one" in the combo box manually. Now when I perform Move Up or Move Down operations the selected index of a combo box is again set to -1. In the Move Up or Move Down operation , I am calling MoveUp and MoveDown methods of the Observable collection. Probelm 3 How to serialize the entire collection in XML.

  • Problem with running a script at startup as root?

    - by Usman Ajmal
    Hi The main question: Is there a way I can run 'completely' one of my script when ubuntu's desktop appears no matter if root , administrator, desktop user or an unprivileged user logged in? What does the script do? The script mounts a partition, looks for a file in that partition and finally on the basis of that file a decision of copying a partition to another partition is made. That copying is done via dd if=/dev/sda2 of=/dev/sda5 When does the script run finely? Script runs smoothly when I run it from the terminal by sudo ./my_copying_script This command asks me for the password of currently logged in user. I enter the password and the script starts working. When does the script NOT run finely? I want to run the script at startup. I set it a startup program by using the Startup Applications utility of Ubuntu. Script ran at startup but exited at the dd command returing following error: dd: opening '/dev/sda2': Permission denied On edk's suggestion I set the owner of my_copying_script as root and set the SUID. Now the permissions of my_copying_script are (-rwsr-sr-x). edk's point of view was that once I set the suid, the startup program will run with the permissions of its owner. I did that but the same /dev/sda2 permission denied error came up. I then prefixed the dd with sudo as mentioned below sudo dd if=/dev/sda2 of=/dev/sda5 but this returned following error: sudo: no tty present and no askpass program specified In other words the mounting failed. If I run the script using sudo ./myProgram i don't face this problem and the drive gets mounted successfully.
