  • SSH to remote host (edgemarc 4200 or 4500 series routers) and pull arp data

    - by MaQleod
    I've been trying to think of a method to do this for days, but have not come up with anything yet. Ideally, this is what I'm looking to do: From a windows XP machine, I need to open an SSH connection to a remote host, send the arp command, and pull the text results of the command back for use on the client. I will need to parse this data and preferably produce a 2D array of IPs and MAC addresses. There will be no shared keys, this is all done with a username and password that will always be different, they will need to be fed into the command via variables that will be pulled from a database using an autoit script based on the WAN ip of the remote host. Now the actual parsing of the data and creation of the array will be easy if I can just get the text of the arp table. Is there any way to ssh to a remote host, run a command and return the data from that command to the client in a batch script or perl script (it is ok if it writes the text to a file, I can read it out of the file later, I just need it to get to the client)?

  • Where in the filesystem should I store shared data?

    - by misterben
    Where in the unix filesystem is the conventional location to save non-user specific data, for example data shared via nfs or ftp, or backups? I could obviously create and use any arbitrary folder (such as /home/shared, /data or /var/data), but I'm really wondering if there are any "best" or "common" practice guidelines. The Filesystem Hierarchy Standard doesn't specify a location for shared data. For backups, I tend to use /var/backups, but as several cronjobs write to it should it really be left for their use?

  • Oracle 11g Data Guard over a WAN

    - by Dave LeJeune
    Hi - We are in process of looking at using Oracle's Data Guard to replicate our 11g instance from a colo facility in Washington DC to Chicago. To give some basics we have approximately 25TB of storage and a healthy transaction rate in the 1-2K/sec range. Also, because we are processing data in real-time we have a 24x7x365 requirement for processing data. We don't have any respites as far as volume except for system upgrades (once every few months) where we take the system offline but then course experience a spike in transactions when we bring the system back on-line. Ideally we would want the second instance in the DG configuration semi-online in a read-only fashion for reports/etc. We evaluated DG in 10g and were not overly impressed and research seemed to show that earlier versions had issues with replication over a WAN but I have heard good things about modifications the product has gone through w/ 11g. Can anyone confirm an instance of this size and transaction rate being replicated over a WAN and if so what is the general latency? An information or experiences with a DG implementation that is of this size and scope would really be helpful (or larger - I also realize we are still relatively small compared to many others out there). Many thanks in advance.

  • searchdisplaycontroller: change the text of the searchbar

    - by kudorgyozo
    Hello, SHORT DESCRIPTION OF PROBLEM: I want to set the text of a searchbar without automatically triggering the search display controller that is bound to it. LONG DESCRIPTION OF PROBLEM: I have an iphone application with a search bar and a search display controller. The searchdisplaycontroller is used for autocomplete. For autocomplete i use an sqlite database. The user enters the first few letters of a keyword and the result are shown in the table of the searchdisplaycontroller. An sql select query is executed for every character typed. this part works ok, the letters have been entered and the results are visible. The problem is the following: If the user selects a row from the table I want to change the text of the searchbar to the text that was selected in the autocomplete results table. I also want to hide the search display controller. This is not working. After the search display controller disappears the textbox in the search bar is empty. I have no idea what's wrong. I didn't think something so simple as changing the text of a textbox can get so complicated. I have tried to change the text in 2 methods: First in the didSelectRowAtIndexPath method (for the search results table of the search display controller), but that didn't help. The text was there while the search display controller was active (animating away) but after that the textbox was empty. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"didSelectRowAtIndexPath"); if (allKeywords.count 0) { didSelectKeyword = TRUE; self.selectedKeyword = (NSString *)[allKeywords objectAtIndex: indexPath.row]; NSLog(@"keyword didselectrow at idxp: %@", self.selectedKeyword); shouldReloadResults = FALSE; [[self.mainViewController keywordSearchBar] setText: selectedKeyword]; //shouldReloadResults = TRUE; [[mainViewController searchDisplayController] setActive:NO animated: YES]; } } I also tried to change it in the searchDisplayControllerDidEndSearch method but that didn't help either. The textbox was...again.. empty. edit: actually it wasnt empty the text was there but after the disappearing animation the results of the autocomplete table are still there. So it ends up getting worse. - (void)searchDisplayControllerDidEndSearch:(UISearchDisplayController *)controller { NSLog(@"searchDisplayControllerDidEndSearch"); if (didSelectKeyword) { shouldReloadResults = FALSE; NSLog(@"keyword sdc didendsearch: %@", selectedKeyword); [[mainViewController keywordSearchBar] setText: selectedKeyword]; // In this method i call another method which selects the data from sqlite. This part is working. - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { NSLog(@"shouldReloadResults : %i", shouldReloadResults); if (shouldReloadResults) { NSLog(@"shouldReloadTableForSearchString: %@", searchString); [self GetKeywords: searchString : @"GB"]; NSLog(@"shouldReloadTableForSearchString vege"); return YES; } return NO; } Please ask me if it's not clear what my problem is. I need your help. Thank you

  • C++ smart pointers: sharing pointers vs. sharing data

    - by Eli Bendersky
    In this insightful article, one of the Qt programmers tries to explain the different kinds of smart pointers Qt implements. In the beginning, he makes a distinction between sharing data and sharing the pointers themselves: First, let’s get one thing straight: there’s a difference between sharing pointers and sharing data. When you share pointers, the value of the pointer and its lifetime is protected by the smart pointer class. In other words, the pointer is the invariant. However, the object that the pointer is pointing to is completely outside its control. We don’t know if the object is copiable or not, if it’s assignable or not. Now, sharing of data involves the smart pointer class knowing something about the data being shared. In fact, the whole point is that the data is being shared and we don’t care how. The fact that pointers are being used to share the data is irrelevant at this point. For example, you don’t really care how Qt tool classes are implicitly shared, do you? What matters to you is that they are shared (thus reducing memory consumption) and that they work as if they weren’t. Frankly, I just don't undersand this explanation. There was a clarification plea in the article comments, but I didn't find the author's explanation sufficient. If you do understand this, please explain. What is this distinction, and how are other shared pointer classes (i.e. from boost or the new C++ standards) fit into this taxonomy? Thanks in advance

  • Dynamically specify and change a Silverlight DataGrid's columns during runtime (MVVM)

    - by Biggert
    What's the best method of dynamically specifying DataGrid columns in the Silverlight DataGrid control at runtime following the MVVM pattern? What I'd like to do would be bind the "DataGrid.Columns" property to a property in my ViewModel so that, if the user adds/removes columns, I simply update the ViewModel property and the DataGrid would change. Problem is, the "DataGrid.Columns" property can't be bound to (I don't think). Because this property isn't available nor is the DataGrid control itself available at the ViewModel level, my current approach is to step outside of the MVVM pattern for this particular implementation and capture certain events in View's code-behind using MVVM Light's Messenger class and then talk directly with the DataGrid control to achieve this capability. I know this is a general statement to this approach without details but is there an easier way... or maybe not so much easier, but a better way that adheres to the MVVM pattern a little better? It's driving me crazy that the DataGrid control's Columns property can't be bound... seems like such a simple thing. FYI - Before it's suggested to use AutoGenerateColumns = True, the class being bound for each item in the collection that's bound to DataGrid.ItemsSource does not have individual properties to identify what is bound to the columns... it's a collection property that contains the columns in order to keep them completely dynamic so that particular path is out. Also, handling the AutoGeneratingColumns and using e.Cancel to show/hide columns is also iffy for this same reason (I think).

  • Objective C - displaying data in NSTextView

    - by Leo
    Hi, I'm having difficulties displaying data in a TextView in iPhone programming. I'm analyzing incoming audio data (from the microphone). In order to do that, I create an object "analyzer" from my SignalAnalyzer class which performs analysis of the incoming data. What I would like to do is to display each new incoming data in a TextView in realtime. So when I push a button, I create the object "analyzer" whiwh analyze the incoming data. Each time there is new data, I need to display it on the screen in a TextView. My problem is that I'm getting an error because (I think) I'm trying to send a message to the parent class (the one taking care of displaying stuff in my TextView : it has a TexView instance variable linked in Interface Builder). What should I do in order to tell my parent class what it needs to display ? Or how sohould I design my classes to display automaticlally something ? Thank you for your help. PS : Here is my error : 2010-04-19 14:59:39.360 MyApp[1421:5003] void WebThreadLockFromAnyThread(), 0x14a890: Obtaining the web lock from a thread other than the main thread or the web thread.

  • Database Change Management - Setup for Initial Create Scripts, Subsequent Migration Scripts

    - by Martin Aatmaa
    I've got a database change management workflow in place. It's based on SQL scripts (so, it's not a managed code-based solution). The basic setup looks like this: Initial/ Generate Initial Schema.sql Generate Initial Required Data.sql Generate Initial Test Data.sql Migration 0001_MigrationScriptForChangeOne.sql 0002_MigrationScriptForChangeTwo.sql ... The process to spin up a database is to then run all the Initlal scripts, and then run the sequential Migration scripts. A tool takes case of the versioning requirements, etc. My question is, in this kind of setup, is it useful to also maintain this: Current/ Stored Procedures/ dbo.MyStoredProcedureCreateScript.sql ... Tables/ dbo.MyTableCreateScript.sql ... ... By "this" I mean a directory of scripts (separated by object type) that represents the create scripts for spinning up the current/latest version of the database. For some reason, I really like the idea, but I can't concretely justify it's need. Am I missing something? The advantages would be: For dev and source control, we would have the same object-per-file setup that we're used to For deployment, we can spin up a new DB instance to the latest version either by running the Initial+Migrate, or by running the scripts from Current/ For dev, we do not need a DB instance running in order to do development. We can do "offline" development on the Current/ folder. The disadvantages would be: For each change, we need to update the scripts in the Current/ folder, as well as create a Migration script (in the Migration/ folder) Thanks in advance for any input!

  • Using Audio Queue Services to play PCM data over a socket connection

    - by Rohan
    I'm writing a remote desktop client for the iPhone and I'm trying to implement audio redirection. The client is connected to the server over a socket connection, and the server sends 32K chunks of PCM data at a time. I'm trying to use AQS to play the data and it plays the first two seconds (1 buffer worth). However, since the next chunk of data hasn't come in over the socket yet, the next AudioQueueBuffer is empty. When the data comes in, I fill the next available buffer with the data and enqueue it with AudioQueueEnqueueBuffer. However, it never plays these buffers. Does the queue stop playing if there are no buffers in the queue, even if you later add a buffer? Here's the relevant part of the code: void wave_out_write(STREAM s, uint16 tick, uint8 index) { if(items_in_queue == NUM_BUFFERS){ return; } if(!playState.busy){ OSStatus status; status = AudioQueueNewOutput(&playState.dataFormat, AudioOutputCallback, &playState, CFRunLoopGetCurrent(), NULL, 0, &playState.queue); if(status == 0){ for(int i=0; i<NUM_BUFFERS; i++){ AudioQueueAllocateBuffer(playState.queue, 40000, &playState.buffers[i]); } AudioQueueAddPropertyListener(playState.queue, kAudioQueueProperty_IsRunning, MyAudioQueuePropertyListenerProc, &playState); status = AudioQueueStart(playState.queue, NULL); if(status ==0){ playState.busy = True; } else{ return; } } else{ return; } } playState.buffers[queue_hi]->mAudioDataByteSize = s->size; memcpy(playState.buffers[queue_hi]->mAudioData, s->data, s->size); AudioQueueEnqueueBuffer(playState.queue, playState.buffers[queue_hi], 0, 0); queue_hi++; queue_hi = queue_hi % NUM_BUFFERS; items_in_queue++; } void AudioOutputCallback(void* inUserData, AudioQueueRef outAQ, AudioQueueBufferRef outBuffer) { PlayState *playState = (PlayState *)inUserData; items_in_queue--; } Thanks!

  • Change Edit Control Block (ECB) Link URL in SharePoint

    - by dirq
    Is there a way to dynamically change the hyperlink associated with an ECB menu in WSS 3.0? For instance, I have a list with 2 fields. One field is hidden and is a link, the other is the title field which has the ECB menu. The title field currently links to the item's view page - but we want it to link to the link-field's url. Is that possible? UPDATE - 5/29/09 9AM I have this so far. See this TechNet post. <script type="text/javascript"> var url = 'GoTo.aspx?ListTitle='+ctx.ListTitle; url += '&ListName='+ctx.listName; url += '&ListTemplate='+ctx.listTemplate; url += '&listBaseType='+ctx.listBaseType; url += '&view='+ctx.view; url += '&'; var a = document.getElementsByTagName('a'); for(i=0;i<=a.length -1;i++) { a[i].href=a[i].href.replace('DispForm.aspx?',url); } </script> This gives me a link like so (formatted so it's easier to see): GoTo.aspx ?ListTitle=MyList &ListName={082BB11C-1941-4906-AAE9-5F2EBFBF052B} &ListTemplate=100 &listBaseType=0 &view={9ABE2B07-2B47-4390-9969-258F00E0812C} &ID=1 My issue now is that the row in the grid gives each item the ID property above but if I change the view or do any filtering you can see that the ID is really just the row number. Can I get the actual item's GUID here? If I can get the item's ID I can send it with the list ID to an application page that will get the right URL from field in the list and forward the user on to the right site.

  • Speed Problem - Animating Height Change in UITableView

    - by Travis
    So I have a huge UITableView, between 1000 and 3000 rows. Each row needs to, when selected, expand to include several buttons. I do this by rendering the buttons below the cell, enabling clipping on the cells, and then just animating a change in height when they're selected. So I have heightForRowAtIndex checking if the row is selected, if so it gives a different height value. To do the animation, I have the following: - (void) tableView: (UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath { [self.tableView beginUpdates]; [self.tableView endUpdates]; } This all works wonderfully until I get around 1000 rows, at which point the animations still work and are still quite smooth, but they lag by a second or two. My first thought was a memory problem, but everything is being autoreleased and upon inspection my application isn't even receiving a memory warning message. So...any ideas on what this might be and how I can erase this lag between selection and change in cell height? Oh, and one last thing - right now I'm testing this on the iPad, so if this is a problem there, I expect it to be worse on our other target devices (iPhone and iPod).

  • Sending data through POST request from a node.js server to a node.js server

    - by Masiar
    I'm trying to send data through a POST request from a node.js server to another node.js server. What I do in the "client" node.js is the following: var options = { host: 'my.url', port: 80, path: '/login', method: 'POST' }; var req = http.request(options, function(res){ console.log('status: ' + res.statusCode); console.log('headers: ' + JSON.stringify(res.headers)); res.setEncoding('utf8'); res.on('data', function(chunk){ console.log("body: " + chunk); }); }); req.on('error', function(e) { console.log('problem with request: ' + e.message); }); // write data to request body req.write('data\n'); req.write('data\n'); req.end(); This chunk is taken more or less from the node.js website so it should be correct. The only thing I don't see is how to include username and password in the options variable to actually login. This is how I deal with the data in the server node.js (I use express): app.post('/login', function(req, res){ var user = {}; user.username = req.body.username; user.password = req.body.password; ... }); How can I add those username and password fields to the options variable to have it logged in? Thanks

  • Using jstl tags in a dynamically created div

    - by George
    I want to be able to show some data based on criteria the user enters in a text field. I can easily take this data, process the form post, and show the data on another page. However, I want to be able to do it all on the same page - they click the button, and a new div shows up with the information. This doesn't seem too complicated, but I want to use jstl tags to format the data like: <c:forEach items="${model.data}" var="d"> <tr> <td><fmt:formatDate type="date" dateStyle="short" timeStyle="default" value="${d.reportDate}" /></td> <td><c:out value="${d.cardType}"/></td> </tr> </c:forEach> If jstl tags are processed when the page loads, can I use that in this new div? Can I update it via a javascript (using prototype) function to display the proper data? Will I be able to do the same thing if they change the criteria and click the submit button again?

  • ASIHTTPRequest POST splits up header + data?

    - by chris.o.
    Hi, I am using ASIHTTPRequest to POST data to a remote server on iPhone 4.2.1. When I make the following post request to our server, I get a 400 response (I removed the IP address): NSString dataString = @"data1=00&data2=00&data3=00"; ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:<ipremoved>]]]; [request appendPostData:[dataString dataUsingEncoding:NSUTF8StringEncoding]]; [request setRequestMethod:@"POST"]; [request addRequestHeader:@"User-Agent" value:@"iphone app"]; [request addRequestHeader:@"Content-Type" value:@"application/octet-stream"]; request.delegate = self; [request startAsynchronous]; When I send the same data using curl, I receive a 200 response: curl -H "User-Agent: iphone app" -H "Accept:" -H "Content-Type:application/octet-stream" --data-ascii "data1=00&data2=00&data3=00" --location <ipremoved> -v My colleague is stating that, in the failure case, the ASIHTTPRequest requires two socket reads: one for the header and one for the data. Apparently the server is not presently equipped to parse this correctly, so I am trying to work around it. If I setup a proxy between iPhone and my Mac and run Paros (to see packets), the problem goes away. Paros combine the header and data so that it is all acquired by the server in a single socket read. I've tried a few things suggested in other posts including disabling persistent connections, but I am not having any luck. I've also tried doing a ASIHTTPFormRequest, but the server does not like the generated data format. Any suggestions would be appreciated. Thanks.

  • WCF for a shared data access

    - by Audrius
    Hi all, I have a little experience with WCF and would like to get your opinion/suggestion on how the following problem can be solved: A web service needs to be accessible from multiple clients simultaneously and service needs to return a result from a shared data set. The concrete project I'm working on has to store a list of IP addresses/ranges. This list will be queried by a bunch of web servers for a validation purposes and we speak of a couple of thousand or more queries per minute. My initial draft approach was to use Windows service as a WCF host with service contract implementing class that is decorated with ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple) that has a list object and a custom locking for accessing it. So basically I have a WCF service singleton with a list = shared data - multiple clients. What I do not like about it is that data and communication layers are merged into one and performance wise this doesn't feel "right". What I really really (- want is Windows service running an instance of IP list holding container class object, a second service running WCF service contract implementation and a way the latter querying the former in a nice way with a minimal blocking. Using another WCF channel would not really take me far away from the initial draft implementation or would it? What approach would you take? Project is still in a very early stage so complete design re-do is not out of question. All ideas are appreciated. Thanks! UPDATE: The data set will be changed dynamically. Web service will have a separate method to add IP or IP range and on top of that there will be a scheduled task that will trigger data cleanup every 10-15 minutes according to some rules. UPDATE 2: a separate benchmark project will be kicked up that should use MSSQL as a data backend (instead on in-memory list).

  • 'Hot code replace' not working -- Eclipse doesn't change any code on JBoss

    - by Bernhard V
    Hello, fellow visitors! I'm currently experiencing a problem with 'hot code replace' not working on Eclipse Galileo and JBoss 4.2.3. Among other applications I'm running an exploded Java WAR on my local JBoss. The project from which it is build is managed by Maven. I build the project using the Maven goal war:exploded and then I copy that directory to JBoss with an ANT script. When I'm now running the application and set a breakpoint anywhere in the code, Eclipse properly halts at that line in the debug mode. But when I'm making a change to the source file and save it, Eclipse doesn't apply this change to the JBoss. For example, when I make a normal code line into a comment, the debugger still steps over this comment as if it was regular Java code. Or when I remove a line, the debugger seems to get out of sync with the file and starts stepping over parenthesis. But I'm not getting any 'hot code replace error'-messages either. It seems to me that Eclipse applies the changes to the source files, but doesn't apply it to the JBoss. Are there any special preferences that have to be turned on in order to make hot code replace work? Or are there any mistakes in how I build and deploy the application to the JBoss? I'd appreciate your help very much. Thank you. Bernhard V

  • Trend analysis using iterative value increments

    - by Dave Jarvis
    We have configured iReport to generate the following graph: The real data points are in blue, the trend line is green. The problems include: Too many data points for the trend line Trend line does not follow a Bezier curve (spline) The source of the problem is with the incrementer class. The incrementer is provided with the data points iteratively. There does not appear to be a way to get the set of data. The code that calculates the trend line looks as follows: import java.math.BigDecimal; import net.sf.jasperreports.engine.fill.*; /** * Used by an iReport variable to increment its average. */ public class MovingAverageIncrementer implements JRIncrementer { private BigDecimal average; private int incr = 0; /** * Instantiated by the MovingAverageIncrementerFactory class. */ public MovingAverageIncrementer() { } /** * Returns the newly incremented value, which is calculated by averaging * the previous value from the previous call to this method. * * @param jrFillVariable Unused. * @param object New data point to average. * @param abstractValueProvider Unused. * @return The newly incremented value. */ public Object increment( JRFillVariable jrFillVariable, Object object, AbstractValueProvider abstractValueProvider ) { BigDecimal value = new BigDecimal( ( ( Number )object ).doubleValue() ); // Average every 10 data points // if( incr % 10 == 0 ) { setAverage( ( value.add( getAverage() ).doubleValue() / 2.0 ) ); } incr++; return getAverage(); } /** * Changes the value that is the moving average. * @param average The new moving average value. */ private void setAverage( BigDecimal average ) { this.average = average; } /** * Returns the current moving average average. * @return Value used for plotting on a report. */ protected BigDecimal getAverage() { if( this.average == null ) { this.average = new BigDecimal( 0 ); } return this.average; } /** Helper method. */ private void setAverage( double d ) { setAverage( new BigDecimal( d ) ); } } How would you create a smoother and more accurate representation of the trend line?

    I need to change the style of the entire row when a checkbox in that row is checked or unchecked. function myFunc() { if ($(".chkbx:checked").length) { $(this).parent().parent().css("background-color","red"); } else { $(this).parent().parent().css("background-color","green"); } } myFunc(); $(".chkbx").change(myFunc); <table> <tr> <td><input type="checkbox" class="chkbx" checked></td> <td>label 1</td> </tr> <tr> <td><input type="checkbox" class="chkbx" checked></td> <td>label 1</td> </tr> <tr> <td><input type="checkbox" class="chkbx" checked></td> <td>label 1</td> </tr> </table> I think I'm missing something here...

  • Change dynamic web reference from web./app.config

    - by Snæbjørn
    I have a problem changing a dynamic web reference in the config file. Changing the url in the config file doesn't have any effect. I have to change the url in .settings and compile for it to change. I added the web reference using the wizard. Set the URL behavior to dynamic, which added the relevant XML tags in config file. In my solution I have the web API (web reference) in a separate project (class lib), so I referenced the project and copied the <applicationSettings> over. <applicationSettings> <StartupProject.Properties.Settings> <setting name="WebReference" serializeAs="String"> <value>http://someurl/somefile.asmx</value> </setting> </StartupProject.Properties.Settings> </applicationSettings> Note that it's <StartupProject.Properties.Settings> and not <WebRefProject.Properties.Settings>. Are there some limitations I'm not aware of or am I doing something wrong?
