Unexplained cache RAM drops on Linux machine

- by FunkyChicken

I run a CentOS 5.7 64 machine with 24gb ram and running kernel 2.6.18-274.12.1.el5. This machine runs only Nginx, php-fpm and Xcache as extra applications. Since about 3 weeks my memory behavior on this machine has changed and I cannot explain why. There are no crons running which flush anything like this. There are also no large numbers of files being deleted/changed during these drops. The 'cached' memory gets dropped about every few hours, but it's never a set gap between flushes, this indicates to me that some bottleneck gets reached instead. It also always seems to be when total memory usages gets to about 18GB, but again, not always exactly 18GB. This is a graph of my memory usage: As you can see in the graph the 'buffers' always stay more or less the same, it is mainly the 'cache' that gets dropped. Running vmstat -m I have outputted the memory usage just before and just after a memory drop. The output is here: http://pastebin.com/diff.php?i=hJqZqztm 'old version' being before, 'new version' being after a drop. About 3 weeks ago my server crashed during a heavy DDOS attack, after I rebooted the machine this odd behavior started. I have checked a bunch of logs, restarted the machine again, and cannot find any indication what changed. During these 'cache' memory drops, my iNode usage drops at the same time. Does anyone have any idea what might be causing this behavior? Clearly my RAM isn't full, so I am curious why this could be happening.

Samba Does Not List Files In Shared Directory

- by Sean M

I am running Samba on a CentOS server, and I am experiencing a problem where it allows me to connect to the server and see a share, but shows the share as an empty directory. I find this behavior strange. Here is the stanza in my smb.conf for the given share: [seanm] path = /home/seanm writeable = yes valid users = seanm, root read only = No Here's what I see on the server side: [seanm@server ~]$ ls -l -rw-r--r-- 1 seanm seanm 40 Jan 4 13:45 pangram.txt And yet: [seanm@client ~]$ smbclient //server/seanm -U seanm -W WORKGROUP Enter seanm's password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.33-3.29.el5_5.1] smb: \> ls . D 0 Fri Jan 7 10:08:55 2011 .. D 0 Fri Jan 7 07:58:31 2011 58994 blocks of size 262144. 50356 blocks available This behavior is present on both a Windows client and a Linux client system. The behavior is present with the firewall on and with the firewall off, so it's not that. Neither /var/log/messages nor /var/log/secure have any complaints about Samba. I doubt that SELinux is a problem: just in case, here are the relevant settings. [root@server ~]# getsebool -a | grep samba samba_domain_controller --> off samba_enable_home_dirs --> on samba_export_all_ro --> off samba_export_all_rw --> off samba_share_fusefs --> off samba_share_nfs --> off use_samba_home_dirs --> on virt_use_samba --> off What am I doing wrong here, and what can I do to fix it?

PuTTY inserts random characters during a session

- by Zachary Polikarpus

I recently started renting space on a remote server so that I could work on a project. I found that a relatively painless way to access it on a windows machine is through PuTTY. However, there is one thing that has always irked me when using it: for seemingly no reason random characters are sometimes inserted at the cursor. Most of the time it is just a single tilde, but rarely it spits out what looks like some escape sequence ([[^8 or the like). It will only occur when I am focused on the window, whether I am typing or 20 feet away from the keyboard. If left for long enough, it will spit tildes at random intervals (average is about 1 minute). Finally, this behavior seems to be inconsistant when running programs such as nano or the mysql interface: in nano, instead of inserting tildes, it will set marks (ctrl-^); in mysql, lines will become un-editable. My question is this: Has anyone else experienced this sort of behavior in PuTTY? And if so, what can be done to prevent/correct this behavior?

How to prevent the command prompt from closing after execution?

- by Sk8erPeter

My problem is that in Windows, there are command line windows that close immediately after execution. To solve this, I want the default behavior to be that the window is kept open. Normally, this behavior can be avoided with three methods that come to my mind: Putting a pause line after batch programs to prompt the user to press a key before exiting Running these batch files or other command line manipulating tools (even service starting, restarting, etc. with net start xy or anything similar) within cmd.exe(Start - Run - cmd.exe) Running these programs with cmd /k like this: cmd /k myprogram.bat But there are some other cases in which the user: Runs the program the first time and doesn't know that the given program will run in Command Prompt (Windows Command Processor) e.g. when running a shortcut from Start menu (or from somewhere else), OR Finds it a little bit uncomfortable to run cmd.exe all the time and doesn't have the time/opportunity to rewrite the code of these commands everywhere to put a pause after them or avoid exiting explicitly. I've read an article about changing default behavior of cmd.exe when opening it explicitly, with creating an AutoRun entry and manipulating its content in these locations: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor\AutoRun HKEY_CURRENT_USER\SOFTWARE\Microsoft\Command Processor\AutoRun (The AutoRun items are _String values_...) I put cmd /d /k as a value of it to give it a try, but this didn't change the behaviour of the stuffs mentioned above at all... It just changed the behaviour of the command line window when opening it explicitly (Start-Run-cmd.exe). So how does it work? Can you give me any ideas to solve this problem?

WCF wsHttpBinding "There was no channel that could accept the message with action"

- by Steffen Schindler

I have a webservice in IIS. I'm trying to call a function but i get an errormessage like: There was no channel that could accept the message with action 'http://Datenlotsen.Cyquest/ICyquestService/ValidateSelfAssessment' I'm hosting it in an IIS in the standard website. There I created a virtual directory named "CyQuestwebservice". For the client side config i'm using Soap UI. That Tool generates the client config from the wsdl. my webconfig looks like this, can you help me?: <system.serviceModel> <extensions> <behaviorExtensions> <add name="wsdlExtensions" type="WCFExtras.Wsdl.WsdlExtensionsConfig, WCFExtras, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </behaviorExtensions> </extensions> <services> <service behaviorConfiguration="CyquestWebService.Service1Behavior" name="CyquestWebService.CyquestService"> <endpoint address="" behaviorConfiguration="EndPointBehavior" binding="wsHttpBinding" bindingNamespace="http://Datenlotsen.Cyquest" contract="CyquestWebService.ICyquestService"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" bindingNamespace="http://Datenlotsen.Cyquest" contract="IMetadataExchange" /> </service> </services> <behaviors> <endpointBehaviors> <behavior name="EndPointBehavior" > <wsdlExtensions location="http://wssdev04.datenlotsen.intern/Cyquestwebservice/CyquestService.svc" singleFile="True"/> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="CyquestWebService.Service1Behavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> <system.diagnostics> <sources> <source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true"> <listeners> <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData= "c:\log\Traces.svclog" /> </listeners> </source> </sources> </system.diagnostics> </configuration>

Unable to set maxReceivedMessageSize through web.config

- by Michael Mortensen

Hello there, I have now investigated the 400 - BadRequest code for the last two hours. A lot of sugestions goes towards ensuring the bindingConfiguration attribute is set correctly, and in my case, it is. Now, I need YOUR help before destroying the building i am in :-) I run a WCF RestFull service (very lightweight, using this resource for inspiration: http://msdn.microsoft.com/en-us/magazine/dd315413.aspx) which (for now) accepts an XmlElement (POX) provided through the POST verb. I am currently ONLY using Fiddler's request builder before implementing a true client (as this is mixed environments). When I do this for XML smaller than 65K, it works fine - larger, it throws this exception: The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element. Here is my web.config file (which I even included the client-tag for (desperate times!)): <system.web> <httpRuntime maxRequestLength="1500000" executionTimeout="180"/> </system.web> <system.serviceModel> <diagnostics> <messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" /> </diagnostics> <bindings> <webHttpBinding> <binding name="WebHttpBinding" maxReceivedMessageSize="1500000" maxBufferPoolSize="1500000" maxBufferSize="1500000" closeTimeout="00:03:00" openTimeout="00:03:00" receiveTimeout="00:10:00" sendTimeout="00:03:00"> <readerQuotas maxStringContentLength="1500000" maxArrayLength="1500000" maxBytesPerRead="1500000" /> <security mode="None"/> </binding> </webHttpBinding> </bindings> <client> <endpoint address="" binding="webHttpBinding" bindingConfiguration="WebHttpBinding" contract="Commerce.ICatalogue"/> </client> <services> <service behaviorConfiguration="ServiceBehavior" name="Catalogue"> <endpoint address="" behaviorConfiguration="RestFull" binding="webHttpBinding" bindingConfiguration="WebHttpBinding" contract="Commerce.ICatalogue" />  </service> </services> <behaviors> <endpointBehaviors> <behavior name="RestFull"> <webHttp/> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceDebug httpHelpPageEnabled="true" includeExceptionDetailInFaults="true"/> <serviceMetadata httpGetEnabled="true"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> Thanks in advance for any help leading to succesfull call with 65K XML ;-)

WCF ReliableSession and Timeouts

- by user80108

I have a WCF service used mainly for managing documents in a repository. I used the chunking channel sample from MS so that I could upload/download huge files. Now I implemented reliable session with the service and I am seeing some strange behaviors. Here are the timeout values I am using. this.SendTimeout = new TimeSpan(0,10,0); this.OpenTimeout = new TimeSpan(0, 1, 0); this.CloseTimeout = new TimeSpan(0, 1, 0); this.ReceiveTimeout = new TimeSpan(0,10, 0); reliableBe.InactivityTimeout = new TimeSpan(0,2,0); I have the following issues. 1. If the Service is not up & running, the clients are not get disconnected after OpenTimeout. I tried it with my test client. Scenario 1: Without Reliable Session: I get the following exception: Could not connect to net.tcp://localhost:8788/MediaManagementService/ep1. The connection attempt lasted for a time span of 00:00:00.9848790. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8788 This is the correct behavior as I have given the OpenTimeout as 1 sec. Scenario 2: With ReliableSession: I get the same exception: Could not connect to net.tcp://localhost:8788/MediaManagementService/ep1. The connection attempt lasted for a time span of 00:00:00.9692460. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8788. But this message comes after around 10 mintes . (I believe after SendTimeout) So here I just have enabled the reliable session and now it looks like the OpenTimeout = SendTimeout for the client. Is this desired behavior? 2: Issue while uploading huge files with ReliableSession: The general rule is that you have to set a huge value for the maxReceivedMessageSize, SendTimeout and ReceiveTimeout. But in the case of Chunking channel, the max received message size doesn't matter as the data is sent in chunks. So I set a huge value for Send and ReceiveTimeout : say 10 hours. Now the upload is going fine, but it has a side effect that, even if the Service is not up, it takes 10 hours to timeout the client connection due to the behavior mentioned in (1). Please let me know your thoughts on this behavior.

WCF - Windows authentication - Security settings require Anonymous...

- by Rashack

Hi, I am struggling hard with getting WCF service running on IIS on our server. After deployment I end up with an error message: Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service. I want to use Windows authentication and thus I have Anonymous access disabled. Also note that there is aspNetCompatibilityEnabled (if that makes any difference). Here's my web.config: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> <bindings> <webHttpBinding> <binding name="default"> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Windows" proxyCredentialType="Windows"/> </security> </binding> </webHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name="AspNetAjaxBehavior"> <enableWebScript /> <webHttp /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="defaultServiceBehavior"> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false" /> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceAuthorization principalPermissionMode="UseWindowsGroups" /> </behavior> </serviceBehaviors> </behaviors> <services> <service name="xxx.Web.Services.RequestService" behaviorConfiguration="defaultServiceBehavior"> <endpoint behaviorConfiguration="AspNetAjaxBehavior" binding="webHttpBinding" contract="xxx.Web.Services.IRequestService" bindingConfiguration="default"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" name="mex" contract="IMetadataExchange"></endpoint> </service> </services> </system.serviceModel> I have searched all over the internet with no luck. Any clues are greatly appreciated.

How to get fast, smooth scrolling with UIWebView?

How to print a specific actionerror message with Struts2 validation?

- by FarmBoy

When using Struts2 validation, when you put the <s:actionerror> tag in your JSP, the default behavior is to display all the action errors at that point in the page. Is there a way to display only specific error messages at that point? For example, in the case of fielderror one only needs to add the fieldName attribute. Is there an attribute of actionerror that accomplishes similar behavior?

Flex 3.5 Accordion and TabNavigator Index Change Bug

- by majgis

I'm using Flex 3.5 with Adobe Flex Builder 3. I have found that if you very rapidly click between multiple headers of an accordion component or the tabs of TabNavigator, these components will begin to exhibit odd, unexpected behavior. Has anyone else experienced this behavior and do you know of a patch that can prevent the user from getting in a situation where the tab/header they click on is not the one made visible?

Ajax call to WCF service returns 12031 ERROR_INTERNET_CONNECTION_RESET on new endpoint

- by cyrix86

I have extended a WCF service with new functionality in the form of a second service contract. The service.cs now implements both contracts. I have added another endpoint to expose the new contract operations. Here is my web.config relating to the service <system.serviceModel> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding" /> </basicHttpBinding> <webHttpBinding> <binding name="XmlHttpBinding"/> </webHttpBinding> </bindings> <services> <service name="MyNamespace.MyService" behaviorConfiguration="MyServiceBehavior">  <endpoint address="xmlHttp1" behaviorConfiguration="XmlHttpBehavior" binding="webHttpBinding" bindingConfiguration="XmlHttpBinding" contract="MyNamespace.IContract1" /> <endpoint address="xmlHttp2" binding="webHttpBinding" behaviorConfiguration="XmlHttpBehavior" bindingConfiguration="XmlHttpBinding" contract="MyNamespace.IContract2" /> <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding" contract="MyNamespace.IContract1" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="MyServiceBehavior">  <serviceMetadata httpGetEnabled="true"/>  <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="XmlHttpBehavior"> <webHttp/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> From Javascript, calling 'http://server/wcfServiceApp/MyService.svc/xmlHttp1/Method1' still works fine. Calling 'http://server/wcfServiceApp/MyService.svc/xmlHttp2/Method2' returns the 12031 error. There must be something simple I'm not doing, any help is appreciated.

Three ways of ataching to events with dojo. What exactly is the difference?

- by Mark

Is the difference here just various syntactical sugars or is there a reason to use one approach over the other? They all work, and to be a little more confusing what is the difference between this and evt.currentTarget? the CSS #reportDetails table tr:hover td, #reportDetails table tr.hover td { background: #aae4e2; color: #333333; } Sample html <div id="reportDetails"> <table> <tr> <td> something</td> <td> soemthing else</td> </tr> <tr> <td> something2</td> <td> soemthing else2</td> </tr> </table> </div> dojo.behavior script dojo.require("dojo.behavior"); if (dojo.isIE <= 6) { dojo.behavior.add({ '#reportDetails tr': { onmouseover: function(evt){ dojo.addClass(evt.currentTarget, "hover");}, onmouseout: function(evt){dojo.removeClass(evt.currentTarget, "hover"); } } }); } dojo.behavior.apply(); dojo.query forEach script if (dojo.isIE <= 6) { dojo.addOnLoad(function() { dojo.query("tr", "reportDetails").forEach(function(node){ node.onmouseover=function(){dojo.addClass(node,"hover");} node.onmouseout=function() {dojo.removeClass(node,"hover");} } }); }); } dojo.query ataching straight to the events if (dojo.isIE <= 6) { dojo.addOnLoad(function(){ dojo.query("tr", "reportDetails") .onmouseover(function(evt){dojo.addClass(evt.currentTarget, "hover");}) .onmouseout(function(evt){dojo.removeClass(evt.currentTarget, "hover");}); }); } I am assuming that evt.currentTarget and node could all be replaced with this and still work. I believe there is no real difference between 2 and 3 but the first one might actually use a different approach.

Disabling email-style usernames in Django 1.2 with django-registration

- by shacker

Django 1.2 allows usernames to take the form of an email address. Changed in Django 1.2: Usernames may now contain @, +, . and - characters I know that's a much-requested feature, but what if you don't want the new behavior? It makes for messy usernames in profile URLs and seems to break django-registration (if a user registers an account with an email-style username, the link in the django-registration activation email returns 404). Does anyone have a recipe for restoring the old behavior and disabling email-style usernames?

Cannot complete a JSONP call from jQuery to WCF

- by Dusda

Okay, I am trying (poorly) to successfully make a JSONP call from jQuery on a test page to a WCF web service running locally, as a cross-domain call. I have, at one point or another, either gotten a 1012 URI denied error, gotten a response but in Xml, or just had no response at all. Currently, the way I have it configured it spits back a 1012. I did not write this web service, so it is entirely possible that I am just missing a configuration setting somewhere, but I've become so frustrated with it that I think just asking on here will be more productive. Thanks guys. Details below. I have a WCF web service with the following method: [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public decimal GetOrderStatusJson(int jobId) I am trying to call this method from a jQuery test page, via a cross-domain JSONP call. <script type="text/javascript"> getJsonAjaxObject( "http://localhost:3960/ProcessRequests.svc/json/GetOrderStatusJson", { "jobId": 232 }); function getJsonAjaxObject(webServiceUrl, jsonData) { var request = { type: "POST", contentType: "application/json; charset=utf-8", url: webServiceUrl, data: jsonData, dataType: "jsonp", success: function(msg) { //success! alert("blah"); }, error: function() { //oh nos alert("bad blah"); } }; $.ajax(request); } </script> Below are the chunks of the web.config I configure for this purpose: <services> <service behaviorConfiguration="MWProcessRequestWCF.ProcessRequestsBehavior" name="MWProcessRequestWCF.ProcessRequests"> <endpoint address="json" behaviorConfiguration="AspNetAjaxBehavior" binding="webHttpBinding" contract="MWProcessRequestWCF.IProcessRequests" /> <endpoint address="" binding="wsHttpBinding" contract="MWProcessRequestWCF.IProcessRequests"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="MWProcessRequestWCF.ProcessRequestsBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="AspNetAjaxBehavior"> <enableWebScript/> </behavior> </endpointBehaviors> </behaviors>

WCF doesn't find client configuration

- by ultraman69

Hi ! I have a WCF service on server B. Then on the machine A is the client, which is a Windows service. In a separate dll stands all the business logic for this service. So my proxy for the WCF is on that side. I have 2 app.config (client side only) : 1 for the service and another one in the dll. So I tried (for test purpose) puting the servicemodel config section in both. Both still, it doesn't work, it says that it can't find the endpoint with that name and for that contract... What I'm trying to do here is modify the configuration programatically. Here' the code in the business layer dll : Dim ep As New EndpointAddress(New Uri(ConfigurationManager.AppSettings(nomServeurCible)), _ EndpointIdentity.CreateDnsIdentity(ConfigurationManager.AppSettings("Identity_" & nomServeurCible))) serviceCible = New ServiceProxy.ExecOperClient("wsHttp", ep) And here is a sample of the config file : <add key="TEST1" value="http://TEST1:8000/MySpacePerso/ExecOperService"/> <add key="TEST1_CertificateSerialNumber" value="10 hj 6y 7b 00 01 32 12 01 21"/> <add key="Identity_TEST1" value="TEST1"/> <system.serviceModel> <client> <endpoint address="http://SERV_NAME:8000/CSSTQDA/ExecOperService" binding="wsHttpBinding" behaviorConfiguration="myClientBehavior" bindingConfiguration="MybindingCon" contract="ExecOper.Service.IExecOper" name="wsHttp"> <identity> <dns value="SERV_CERT_NAME"/> </identity> </endpoint> </client> <bindings> <wsHttpBinding> <binding name="MybindingCon"> <security mode="Message"> <message clientCredentialType="UserName" /> </security> </binding> </wsHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceTraitementBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="myClientBehavior"> <clientCredentials> <serviceCertificate> <authentication certificateValidationMode="ChainTrust" revocationMode="NoCheck"/> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors>

Docking *inside* an editor

- by Andy Thomas-Cramer

I have a document type which has multiple presentations. Say I want to display the document in an RCP editor with a customizable subset of those presentations, in a layout chosen by the user. One option that has come up is docking-like behavior for the panels inside an individual editor, with drag-and-drop, resizing, closing, maybe rollover and floating. Clearly this would need usability testing, but my question here is of feasibility. Are there any existing libraries or e4 plans to support behavior like this?

Hiding a navigation bar via scrolling (safari style)

- by eagle

After a page is loaded in Safari on the iPhone, when you begin scrolling down, the navigation bar is also scrolled out of view. When you scroll back up, the navigation scrolls back into view. I'm looking to implement this same behavior using a UIWebView underneath the UINavigationBar, but I'm guessing it should be possible with any UIScrollView descendant. How can this behavior be implemented?
