  • Managing multiple reverse proxies for one virtual host in apache2

    - by Chris Betti
    I have many reverse proxies defined for my js-host VirtualHost, like so: /etc/apache2/sites-available/js-host <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPreserveHost On ProxyPass /serviceA http://192.168.100.50/ ProxyPassReverse /serviceA http://192.168.100.50/ ProxyPass /serviceB http://192.168.100.51/ ProxyPassReverse /serviceB http://192.168.100.51/ [...] ProxyPass /serviceZ http://192.168.100.75/ ProxyPassReverse /serviceZ http://192.168.100.75/ </VirtualHost> The js-host site is acting as shared config for all of the reverse proxies. This works, but managing the proxies involves edits to the shared config, and an apache2 restart. Is there a way to manage individual proxies with a2ensite and a2dissite (or a better alternative)? My main objective is to isolate each proxy config as a separate file, and manage it via commands. First Attempt I tried making separate files with their own VirtualHost entries for each service: /etc/apache2/sites-available/js-host-serviceA <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPass /serviceA http://192.168.100.50/ ProxyPassReverse /serviceA http://192.168.100.50/ </VirtualHost> /etc/apache2/sites-available/js-host-serviceB <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPass /serviceB http://192.168.100.51/ ProxyPassReverse /serviceB http://192.168.100.51/ </VirtualHost> The problem with this is apache2 loads the first VirtualHost for a particular ServerName, and ignores the rest. They aren't "merged" somehow as I'd hoped.

  • Wireless not working - HP Probook 4540s

    - by Oguzhan
    I just installed Ubuntu 12.04 on 3 HP Probook 4540s's, and none of them seems to be able to connect to wireless networks. I have 1 Probook 4540s with Windows 7 installed and I can access wlan from it. I tried installing the necessary drivers from HP's website, but it still doesn't seem to be working. I've seen other people with different Probooks having similar problems, but their computers seem to be able to detect and even attempt to connect wlans, while mine doesn't even acknowledge that it has wireless. Any help would be appreciated. lspci: 00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Ivy Bridge PCI Express Root Port (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 00:14.0 USB controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Panther Point MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 1 (rev c4) 00:1c.2 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 3 (rev c4) 00:1c.3 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 4 (rev c4) 00:1c.5 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 6 (rev c4) 00:1d.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Panther Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Panther Point 6 port SATA Controller [AHCI mode] (rev 04) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Thames [Radeon 7500M/7600M Series] 03:00.0 System peripheral: JMicron Technology Corp.

  • BizTalk 2009 - Naming Guidelines

    - by StuartBrierley
    The following is effectively a repost of the BizTalk 2004 naming guidlines that I have previously detailed.  I have posted these again for completeness under BizTalk 2009 and to allow an element of separation in case I find some reason to amend these for BizTalk 2009. These guidlines should be universal across any version of BizTalk you may wish to apply them to. General Rules All names should be named with a Pascal convention. Project Namespaces For message schemas: [CompanyName].XML.Schemas.[FunctionalName]* Examples:  ABC.XML.Schemas.Underwriting DEF.XML.Schemas.MarshmellowTradingExchange * Donates potential for multiple levels of functional name, such as Underwriting.Dictionary.Valuation For web services: [CompanyName].Web.Services.[FunctionalName] Examples: ABC.Web.Services.OrderJellyBeans For the main BizTalk Projects: [CompanyName].BizTalk.[AssemblyType].[FunctionalName]* Examples: ABC.BizTalk.Mappings.Underwriting ABC.BizTalk.Orchestrations.Underwriting * Donates potential for multiple levels of functional name, such as Mappings.Underwriting.Valuations Assemblies BizTalk Assembly names should match the associated Project Namespace, such as ABC.BizTalk.Mappings.Underwriting. This pertains to the formal assembly name and the DLL name. The Solution name should take the name of the main project within the solution, and also therefore the namespace for that project. Although long names such as this can be unwieldy to work with, the benefits of having the full scope available when the assemblies are installed on the target server are generally judged to outweigh this inconvenience. Messaging Artifacts Artifact Standard Notes Example Schema <DescriptiveName>.xsd   .NET Type name should match, without file extension.    .NET Namespace will likely match assembly name. PurchaseOrderAcknowledge_FF.xsd  or FNMA100330_FF.xsd Property Schema <DescriptiveName>.xsd Should be named to reflect possible common usage across multiple schemas  IspecMessagePropertySchema.xsd UnderwritingOrchestrationKeys.xsd Map <SourceSchema>2<DestinationSchema>.btm Exceptions to this may be made where the source and destination schemas share the majority of the name, such as in mainframe web service maps InstructionResponse2CustomEmailRequest.btm (exception example) AccountCustomerAddressSummaryRequest2MainframeRequest.btm Orchestration <DescriptiveName>.odx   GetValuationReports.odx SendMTEDecisionResponse.odx Send/Receive Pipeline <DescriptiveName>.btp   ValidatingXMLReceivePipeline.btp FlatFileAssembler.btp Receive Port A plainly worded phrase that will clearly explain the function.    FraudPreventionServices LetterProcessing   Receive Location A plainly worded phrase that will clearly explain the function.  ? Do we want to include the transport type here ? Arrears Web Service Send Port Group A plainly worded phrase that will clearly explain the function.   Customer Updates Send Port A plainly worded phrase that will clearly explain the function.    ABCProductUpdater LogLendingPolicyOutput Parties A meaningful name for a Trading Partner. If dealing with multiple entities within a Trading Partner organization, the Organization name could be used as a prefix.   Roles A meaningful name for the role that a Trading Partner plays.     Orchestration Workflow Shapes Shape Standard Notes Example Scopes <DescriptionOfContainedWork> or <DescOfcontainedWork><TxType>   Including info about transaction type may be appropriate in some situations where it adds significant documentation value to the diagram. HandleReportResponse         Receive Receive<MessageName> Typically, MessageName will be the same as the name of the message variable that is being received “into”. ReceiveReportResponse Send Send<MessageName> Typically, MessageName will be the same as the name of the message variable that is being sent. SendValuationDetailsRequest Expression <DescriptionOfEffect> Expression shapes should be named to describe the net effect of the expression, similar to naming a method.  The exception to this is the case where the expression is interacting with an external .NET component to perform a function that overlaps with existing BizTalk functionality – use closest BizTalk shape for this case. CreatePrintXML Decide <DescriptionOfDecision> A description of what will be decided in the “if” branch Report Type? Perform MF Save? If-Branch <DescriptionOfDecision> A (potentially abbreviated) description of what is being decided Mortgage Valuation Yes Else-Branch Else Else-branch shapes should always be named “Else” Else Construct Message (Assign) Create<Message> (for Construct)     <ExpressionDescription> (for expression) If a Construct shape contains a message assignment, it should be prefixed with “Create” followed by an abbreviated name of the message being assigned.    The actual message assignment shape contained should be named to describe the expression that is contained. CreateReportDataMV   which contains expression: ExtractReportData Construct Message (Transform) Create<Message> (for Construct)   <SourceSchema>2<DestSchema> (for transform) If a Construct shape contains a message transform, it should be prefixed with “Create” followed by an abbreviated name of the message being assigned.   The actual message transform shape contained should generally be named the same as the called map.  CreateReportDataMV   which contains transform: ReportDataMV2ReportDataMV                 Construct Message (containing multiple shapes)   If a Construct Message shape uses multiple assignments or transforms, the overall shape should be named to communicate the net effect, using no prefix.     Call/Start Orchestration Call<OrchestrationName>   Start<OrchestrationName>     Throw Throw<ExceptionType> The corresponding variable name for the exception type should (often) be the same name as the exception type, only camel-cased. ThrowRuleException, which references the “ruleException” variable.     Parallel <DescriptionOfParallelWork> Parallel shapes should be named by a description of what work will be done in parallel   Delay <DescriptionOfWhatWaitingFor> Delay shapes should be named by a description of what is being waited for.  POAcknowledgeTimeout Listen <DescriptionOfOutcomes> Listen shapes should be named by a description that captures (to the degree possible) all the branches of the Listen shape POAckOrTimeout FirstShippingBid Loop <DescriptionOfLoop> A (potentially abbreviated) description of what the loop is. ForEachValuationReport WhileErrorFlagTrue Role Link   See “Roles” in messaging naming conventions above.   Suspend <ReasonDescription> Describe what action an administrator must take to resume the orchestration.  More detail can be passed to error property – and should include what should be done by the administrator before resuming the orchestration. ReEstablishCreditLink Terminate <ReasonDescription> Describe why the orchestration terminated.  More detail can be passed to error property. TimeoutsExpired Call Rules Call<PolicyName> The policy name may need to be abbreviated. CallLendingPolicy Compensate Compensate or Compensate<TxName> If the shape compensates nested transactions, names should be suffixed with the name of the nested transaction – otherwise it should simple be Compensate. CompensateTransferFunds Orchestration Types Type Standard Notes Example Multi-Part Message Types <LogicalDocumentType>   Multi-part types encapsulate multiple parts.  The WSDL spec indicates “parts are a flexible mechanism for describing the logical abstract content of a message.”  The name of the multi-part type should correspond to the “logical” document type, i.e. what the sum of the parts describes. InvoiceReceipt   (which might encapsulate an invoice acknowledgement and a payment voucher.) Multi-Part Messsage Part <SchemaNameOfPart> Should be named (most often) simply for the schema (or simple type) associated with the part. InvoiceHeader Messages <SchemaName> or <MuliPartMessageTypeName> Should be named based on the corresponding schema type or multi-part message type.  If there is more than one variable of a type, name for its use within the orchestration. ReportDataMV UpdatedReportDataMV Variables <DescriptiveName>   TargetFilePath StringProcessor Port Types <FunctionDescription>PortType Should be named to suggest the nature of an endpoint, with pascal casing and suffixed with “PortType”.   If there will be more than one Port for a Port Type, the Port Type should be named according to the abstract service supplied.   The WSDL spec indicates port types are “a named set of abstract operations and the abstract messages involved” that also encapsulates the message pattern (i.e. one-way, request-response, solicit-response) that all operations on the port type adhere to. ReceiveReportResponsePortType  or CallEAEPortType (This is a two way port, so Receove or Send alone would not be appropriate.  Could have been ProcessEAERequestPortType etc....) Ports <FunctionDescription>Port Should be named to suggest a grouping of functionality, with pascal casing and suffixed with “Port.”  ReceiveReportResponsePort CallEAEPort Correlation types <DescriptiveName> Should be named based on the logical name of what is being used to correlate.  PurchaseOrderNumber Correlation sets <DescriptiveName> Should be named based on the corresponding correlation type.  If there is more than one, it should be named to reflect its specific purpose within the orchestration.   PurchaseOrderNumber Orchestration parameters <DescriptiveName> Should be named to match the caller’s names for the corresponding variables where appropriate.

  • Changing the BizTalk message output file name

    - by Bill Osuch
    By default, BizTalk creates the filename of the message dropped to a send port as %MessageID%, which is the unique identifier (GUID) of the message. What if you want to create your own filename? To start, create a simple schema, and a basic orchestration that will receive the message and send it right back out, like this: If you deploy this and wire up the ports, you can drop an xml file into your receive port and have it come out at your send port named something like {7A63CAF8-317B-49D5-871F-9FD57910C3A0}.xml. Now, we'll create a new message with a custom filename. First, create a new orchestration variable called NewFileName, of the type System.String. Next, create a second message using the same schema as the message you're receiving in the Receive shape. Now, drag a Construct Message shape to the orchestration. In the shape's properties, set Messages Constructed to be the new message you just created. Double click the Message Assignment shape (inside the Construct shape...) and paste in the following code: Message_2 = Message_1;   NewFileName = Message_1(FILE.ReceivedFileName); NewFileName = NewFileName.Replace(".xml","_"); NewFileName = NewFileName + "output_" + System.DateTime.Now.Year.ToString() + "-" + System.DateTime.Now.Month.ToString();   Message_2(FILE.ReceivedFileName) = NewFileName; Here we make a copy of the received message, get it's original file name (ReceivedFileName), replace its extension with an underscore, and date-stamp it. Finally, add a Send shape and a Port to the surface, and configure them to send the message you just created. You should wind up with an orchestration like this: Deploy it, and create a new send port. It should be just about identical to the first send port, except this time the file name will be "%SourceFileName%.xml" (without the quotes of course). Fire up the application, drop in a test file, and you should now get both the xml file named with a GUID, and a second file named something along the lines of "MySchemaTestFile_output_2011-6.xml".

  • Keep Your Eye on the Ball

    - by [email protected]
    With the FIFA World Cup 2010 in South Africa almost a week underway, the soccer fans all around the World are talking about at least 2 things. That typical vuvuzela sound and the new Jabulani ball, saying it moves unpredictably, is difficult to handle and somehow the altitude of the World Cup stadiums also seem to be a contributing factor.(Picture taken from http://www.flickr.com/photos/warrenski/4143923059/ under a Creative Commons license)Although the FIFA states that it hasn't received any official complaints, the end users don't seem to be very happy with this new ball. This brings me to a comparison with IT management and testing. When you're in a situation where you're introducing a new product, in IT terms, introducing a new application, you would like to test all possible scenarios that your end users could be using and experiencing. However, that's a very time and resource intensive process to do for every application change or update.  It's like getting ready for the big game but you have no game plan.That's why a new approach has been developed. One that's based on the 80/20 rule. Testing 80% of the application will cost about 20% of the efforts. The remaining 20% of your application will not be tested before deployment, but monitored with a real user monitoring solution immediately after deployment. These tools track all user experiences, including error messages and the performance and availability metrics from an end user perspective. Should any anomaly occur, you would be able to repair it quickly so you and your end users can get back into the game.These real user sessions can be easily converted into testing scripts, so the 80% of the application testing can be complimented with the remaining 20%.Oracle Enterprise Manager 11g group of products offers both the real user monitoring solution with Oracle Real User Experience Insight, as well as the required testing solution with Oracle Application Testing Suite. Visit our Oracle Enterprise Manager 11g resource center and find out how it's Business-Driven IT Management approach will help you keep your eye on your business ball.Happy World Cup.

  • Algorithm for a lucky game [on hold]

    - by Ronnie
    Assume we have the following Keno(lottery type) game: From 80 numbers(from 1 to 80), 20 are being drawn. The players choose 1 or 2 or 3..... or 12 numbers to play(12 categories). If they choose for example 4 then they win if they predict correctly a certain amount of numbers(2,3 or 4) from the 4 they have played and lose if the predict only 1 or 0 numbers. They win X times their money accordingly to some predefined factor depending on how many numbers they predict from each category. The same with the other categories. And e.g 11 out of 11 gives 250000 times your money and 12 out of 12 gives 1000000 your money. So the company would want to avoid winnings so high. Every draw by the company is being made every 5 minutes and in each draw around 120000 (let's say) different predictions(Keno tickets) are being played. Let's assume 12000 are being played in category 10 and 12000 in category 11 and also 12000 in category 12. I'm wondering if there is an algorithm to allow the company that provides the game in the 5 minutes between the drawings, to find a 20 number set, in order to avoid any "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10" winning ticket. That means is there any algorithm, where in a time of less than 1 minute approximately(in todays hardware), to be able to find a 20 number set so that none of the 12000 12 and 11 and 10 number sets that the players played(in categories 10,11 and 12) contains any winning of "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10"? Or even better the generalization of the problem: What is the best algorithm(from a perspective of minimal time), to be able to find a Y number set from numbers 1 to Z(e.g Y=20, Z=80) so that none of the X sets of K-numbers that are being played(in category K) contains more than K-m numbers from the Y-set? (Note that for Y=K and m=1 there is a practical algorithm.)

  • Remove IP address from the URL of website using apache

    - by sapatos
    I'm on an EC2 instance and have a domain domain.com linked to the EC2 nameservers and it happily is serving my pages if I type domain.com in the URL. However when the page is served it resolves the url to: 1.1.1.10/directory/page.php. Using apache I've set up the following VirtualHost, following examples provided at http://httpd.apache.org/docs/2.0/dns-caveats.html Listen 80 NameVirtualHost 1.1.1.10:80 <VirtualHost 1.1.1.10:80> DocumentRoot /var/www/html/directory ServerName domain.com # Other directives here ... <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$"> Header set Cache-Control "max-age=290304000, public" </FilesMatch> </VirtualHost> However I'm not getting any changes to how the URL is displayed. This is the only VirtualHost configured on this site and I've confirmed its the one being used as I've managed to break it a number of times whilst experimenting with the configuration. The route53 entries I have are: domain.com A 1.1.1.10 domain.com NS ns-11.awsdns-11.com ns-111.awsdns-11.net ns-1111.awsdns-11.org ns-1111.awsdns-11.co.uk domain.com SOA ns-11.awsdns-11.com. awsdns-hostmaster.amazon.com. 1 1100 100 1101100 11100

  • Data Aggregation of CSV files java

    - by royB
    I have k csv files (5 csv files for example), each file has m fields which produce a key and n values. I need to produce a single csv file with aggregated data. I'm looking for the most efficient solution for this problem, speed mainly. I don't think by the way that we will have memory issues. Also I would like to know if hashing is really a good solution because we will have to use 64 bit hashing solution to reduce the chance for a collision to less than 1% (we are having around 30000000 rows per aggregation). For example file 1: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,50,60,70,80 a3,b2,c4,60,60,80,90 file 2: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,30,50,90,40 a3,b2,c4,30,70,50,90 result: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,80,110,160,120 a3,b2,c4,90,130,130,180 algorithm that we thought until now: hashing (using concurentHashTable) merge sorting the files DB: using mysql or hadoop or redis. The solution needs to be able to handle Huge amount of data (each file more than two million rows) a better example: file 1 country,city,peopleNum england,london,1000000 england,coventry,500000 file 2: country,city,peopleNum england,london,500000 england,coventry,500000 england,manchester,500000 merged file: country,city,peopleNum england,london,1500000 england,coventry,1000000 england,manchester,500000 The key is: country,city. This is just an example, my real key is of size 6 and the data columns are of size 8 - total of 14 columns. We would like that the solution will be the fastest in regard of data processing.

  • Mapping XFCE4/xRDP sessions to users

    - by garrilla
    I have Ubuntu 13.10 with Xubuntu Desktop - XFCE4. I'm trying to use XDRP to allow MS Windows users to login to the machine with their own user. I've been a lot around the houses with this! I've find two half-way solutions, but can't get them to work as I'd like... 1) in /etc/xrdp/xrdp.ini I set the port to -1 [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=-1 each time any user logs on they get a new session - they can never go back to their original session 2) in /etc/xrdp/xrdp.ini I set the port to 5912 (e.g) [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5912 each time any user logs on they always log on to the same session irrespective of their logon details ??) I found a mid-way solution, to create a lot of sessions by adding adding additional options in the xrdp.ini e.g. [xrdp8] name=Bob's Logon lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5913 [xrdp9] name=Jill's Logon lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5914 and so on, but he problem with this is that Jill can still log into Bob's remote session ??? Is it possible to to do what I'm trying to do? Maybe I have to use different tools?

  • UFW blocking random packets on 443

    - by s2jcpete
    All, I have UFW setup to allow traffic on port 443. It works as expected, though I have a large amount of UFW Block log entries. To Action From -- ------ ---- 80 ALLOW Anywhere 443 ALLOW Anywhere 22222 ALLOW Anywhere 80 ALLOW Anywhere (v6) 443 ALLOW Anywhere (v6) 22222 ALLOW Anywhere (v6) However in my syslog file I see this: [UFW BLOCK] IN=eth0 OUT= MAC=XXX SRC=<foreignip> DST=<serverip> LEN=40 TOS=0x00 PREC=0x00 TTL=116 ID=22025 DF PROTO=TCP SPT=49622 DPT=443 WINDOW=0 RES=0x00 ACK RST URGP=0 About 30 or so seconds later pound (which I'm using for SSL decryption and port redirection) throws a connection timed out messsage. I'm assuming this is because UFW is blocking the packet. I'm at a loss as to an explination. Could the packet be malformed or something, is this normal? Edit - I have since changed the /etc/defaults/ufw and set ipv6=no, so the v6 rules are no longer in the mix. The server is still showing the block / connection timed out behavior though. The new ufw status output is: Status: active Logging: on (low) Default: deny (incoming), allow (outgoing) New profiles: skip To Action From -- ------ ---- 80 ALLOW IN Anywhere 443 ALLOW IN Anywhere 22222 ALLOW IN Anywhere

  • Remote Access to Owncloud Server

    - by John
    I'm currently trying to setup my own own-cloud server, and I've got it fully installed, configured, and accessible from within my own local network. I cannot figure out how to access it from the outside. So far I've: Successfully setup port-forwarding on my local router. I've done so via 'single port forwarding' and 'port range forwarding' Ports 80, 443, 3306 (Apache-Full and MySQL) Successfully obtained my external IP address. I've also tested this magic number from within the network at #insertIPhere/owncloud and it did work. Successfully setup the server using SQLite Successfully setup the server using MySQL Created the following exceptions in my firewall: Allow In Port 80 (Apache Full) Allow In Port 443 (Apache Full) Allow In Port 3306 (MySQL) Tried connecting from several different remote networks, as to troubleshoot something on their end As far as trying to access it, I'm doing so through Google-Chrome and Mozilla Firefox trying to reach the server through #insertIPhere/owncloud using the above public IP address. So what have I missed, and how do I access my server from outside? Thanks in advance for your help and time, and I apologize in advance for what will probably result in my noobish mistake in networking. I've looked at the official documentation. And also this question here.

  • Google Analytics API data for goals (funnels) doesn't match - how do they reconcile?

    - by bkgraham
    I have a Google Analytics account with a well-functioning funnel made up of 4 goals. I can query the API and get the data out, but it does not match the funnel report in Analytics. Without getting into specific values, I can give you an example with faked data. Here's how the funnel might look: Shopping Cart 100 > 100 > 20 80 (80%) Address Page 5 > 85 > 25 60 (71%) Payment Page 2 > 62 > 10 52 (84%) Checkout 1 > 53 (49.07% funnel conversion rate) Okay, so you would expect the API to output data something like this: goal1Starts goal1Completions goal1Abandons 100 80 20 goal2Starts goal2Completions goal2Abandons 85 60 25 goal3Starts goal3Completions goal3Abandons 62 52 10 goal4Starts goal4Completions goal4Abandons 53 53 0 Instead, it's different. Firstly, the abandons are associated with the following goal (so goal1 always has 0 abandons and goal4 always has 0 abandons. Okay, I can work with that. What's confusing is that the numbers are always a little different. The goal1Completions always match the report, as do the goal4Completions, but everything else is off by a small amount. Sometimes it's only 2 visits, other times it's off by 50. For the report above here's the kind of results I would tend to get: goal1Starts goal1Completions goal1Abandons 100 100 0 goal2Starts goal2Completions goal2Abandons 105 84 21 goal3Starts goal3Completions goal3Abandons 90 65 25 goal4Starts goal4Completions goal4Abandons 58 53 5 Here's what I know: Goal(n)Completions + Goal(n)Abandons = Goal(n)Starts Goal(n)Starts = Goal(n-1)Completions Goal(n)Starts - Goal(n-1)Completions != reported number entering at that level That third one is particularly disappointing. So, here's my question: What data do I need to pull from the API in order to recreate the counts in the Funnel report in Google Analytics? I don't need the pages exited to entering from - just the counts at every level.

  • Virtual Hosts Not Working (12.10)

    - by lolajl
    I'm trying to get virtual hosts up and running on my Ubuntu laptop that has 12.10 installed. I'm running Apache2, and I enabled the virtual hosting module. When I go to 12.0.0.1, I'm able to get the default page. When I go to example.local, I just get the search engine results, instead of the "hey, you're seeing this" page I set up in that directory (/var/www/example.local). I even made sure I have only one "NameVirtualHost *:80" variable active. Checking error.log, nothing obvious seems to jump out as being amiss. here's what I have in the respective files: example.local ServerName example.local ServerAdmin webmaster@localhost DocumentRoot /var/www/example.local <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/example.local> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

  • Getting Indy Error "Could not bind socket. Address and port are already in use"

    - by M Schenkel
    I have developed a Delphi web server application (TWebModule). It runs as a ISAPI DLL on Apache under Windows. The application in turn makes frequent https calls to other web sites using the Indy TIdHTTP component. Periodically I get this error when using the TIdHTTP.get method: Could not bind socket. Address and port are already in use Here is the code: IdSSLIOHandlerSocket1 := TIdSSLIOHandlerSocketOpenSSL.create(nil); IdHTTP := TIdHTTP.create(nil); idhttp.handleredirects := True; idhttp.OnRedirect := DoRedirect; with IdSSLIOHandlerSocket1 do begin SSLOptions.Method := sslvSSLv3; SSLOptions.Mode := sslmUnassigned; SSLOptions.VerifyMode := []; SSLOptions.VerifyDepth := 2; end; with IdHTTP do begin IOHandler := IdSSLIOHandlerSocket1; ProxyParams.BasicAuthentication := False; Request.UserAgent := 'Test Google Analytics Interface'; Request.ContentType := 'text/html'; request.connection := 'keep-alive'; Request.Accept := 'text/html, */*'; end; try idhttp.get('http://www.mysite.com......'); except ....... end; IdHTTP.free; IdSSLIOHandlerSocket1.free; I have read about the reusesocket method, which can be set on both the TIdHttp and TIdSSLLIOHandlerSocketOpenSSL objects. Will setting this to rsTrue solve my problems? I ask because I have not been able to replicate this error, it just happens periodically. Other considerations: I know multiple instances of TWebModule are being spawned. Would wrapping all calls to TIdHttp.get within a TCriticalSection solve the problem?

  • make local only daemon listening on different interface (using iptables port forwarding)?

    - by UniIsland
    i have a daemon program which listens on 127.0.0.1:8000. i need to access it when i connect to my box with vpn. so i want it to listen on the ppp0 interface too. i've tried the "ssh -L" method. it works, but i don't think it's the right way to do that, having an extra ssh process running in the background. i tried the "netcat" method. it exits when the connection is closed. so not a valid way for "listening". i also tried several iptables rules. none of them worked. i'm not listing here all the rules i've used. iptables -A FORWARD -j ACCEPT iptables -t nat -A PREROUTING -i ppp+ -p tcp --dport 8000 -j DNAT --to-destination 127.0.0.1:8000 the above ruleset doesn't work. i have net.ipv4.ip_forward set to 1. anyone knows how to redirect traffic from ppp interface to lo? say, listen on "192.168.45.1:8000 (ppp0)" as well as "127.0.0.1:8000 (lo)" there's no need to alter the port. thanx

  • failed to connect to any given host:port - RoR Error?

    - by Sam Hursey
    Hi all I'm very new to Ruby on Rails so please go easy! I've uploaded the whole application to the server (Dreamhost) and gone through the steps. But when I try to run it I get the following error: failed to connect to any given host:port (Mongo::ConnectionFailure) I have installed the Mongo gem; but maybe I haven't got it configured correctly? I know you can't use localhost for describing where a Dreamhost mysql database is; might it be something like that?

  • HDFS some datanodes of cluster are suddenly disconnected while reducers are running

    - by user1429825
    I have 8 slave computers and 1 master computer for running Hadoop (ver 0.21) some datanodes of cluster are suddenly disconnected while I was running MapReduce code on 10GB data After all mappers finished and around 80% of reducers was processed, randomly one or more datanode disconned from network. and then the other datanodes start to disappear from network even if I killed the MapReduce job when I found some datanode was disconnected. I've tried to change dfs.datanode.max.xcievers to 4096, turned off fire-walls of all computing node, disabled selinux and increased the number of file open limit to 20000 but they didn't work at all... anyone have a idea to solve this problem? followings are error log from mapreduce 12/06/01 12:31:29 INFO mapreduce.Job: Task Id : attempt_201206011227_0001_r_000006_0, Status : FAILED java.io.IOException: Bad connect ack with firstBadLink as ***.***.***.148:20010 at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.createBlockOutputStream(DFSOutputStream.java:889) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.nextBlockOutputStream(DFSOutputStream.java:820) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:427) and followings are logs from datanode 2012-06-01 13:01:01,118 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: Receiving block blk_-5549263231281364844_3453 src: /*.*.*.147:56205 dest: /*.*.*.142:20010 2012-06-01 13:01:01,136 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: DatanodeRegistration(*.*.*.142:20010, storageID=DS-1534489105-*.*.*.142-20010-1337757934836, infoPort=20075, ipcPort=20020) Starting thread to transfer block blk_-3849519151985279385_5906 to *.*.*.147:20010 2012-06-01 13:01:19,135 WARN org.apache.hadoop.hdfs.server.datanode.DataNode: DatanodeRegistration(*.*.*.142:20010, storageID=DS-1534489105-*.*.*.142-20010-1337757934836, infoPort=20075, ipcPort=20020):Failed to transfer blk_-5797481564121417802_3453 to *.*.*.146:20010 got java.net.ConnectException: > Connection timed out at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:701) at org.apache.hadoop.net.SocketIOWithTimeout.connect(SocketIOWithTimeout.java:206) at org.apache.hadoop.net.NetUtils.connect(NetUtils.java:373) at org.apache.hadoop.hdfs.server.datanode.DataNode$DataTransfer.run(DataNode.java:1257) at java.lang.Thread.run(Thread.java:722) 2012-06-01 13:06:20,342 INFO org.apache.hadoop.hdfs.server.datanode.DataBlockScanner: Verification succeeded for blk_6674438989226364081_3453 2012-06-01 13:09:01,781 WARN org.apache.hadoop.hdfs.server.datanode.DataNode: DatanodeRegistration(*.*.*.142:20010, storageID=DS-1534489105-*.*.*.142-20010-1337757934836, infoPort=20075, ipcPort=20020):Failed to transfer blk_-3849519151985279385_5906 to *.*.*.147:20010 got java.net.SocketTimeoutException: 480000 millis timeout while waiting for channel to be ready for write. ch : java.nio.channels.SocketChannel[connected local=/*.*.*.142:60057 remote=/*.*.*.147:20010] at org.apache.hadoop.net.SocketIOWithTimeout.waitForIO(SocketIOWithTimeout.java:246) at org.apache.hadoop.net.SocketOutputStream.waitForWritable(SocketOutputStream.java:164) at org.apache.hadoop.net.SocketOutputStream.transferToFully(SocketOutputStream.java:203) at org.apache.hadoop.hdfs.server.datanode.BlockSender.sendChunks(BlockSender.java:388) at org.apache.hadoop.hdfs.server.datanode.BlockSender.sendBlock(BlockSender.java:476) at org.apache.hadoop.hdfs.server.datanode.DataNode$DataTransfer.run(DataNode.java:1284) at java.lang.Thread.run(Thread.java:722) hdfs-site.xml <configuration> <property> <name>dfs.name.dir</name> <value>/home/hadoop/data/name</value> </property> <property> <name>dfs.data.dir</name> <value>/home/hadoop/data/hdfs1,/home/hadoop/data/hdfs2,/home/hadoop/data/hdfs3,/home/hadoop/data/hdfs4,/home/hadoop/data/hdfs5</value> </property> <property> <name>dfs.replication</name> <value>3</value> </property> <property> <name>dfs.datanode.max.xcievers</name> <value>4096</value> </property> <property> <name>dfs.http.address</name> <value>0.0.0.0:20070</value> <description>50070 The address and the base port where the dfs namenode web ui will listen on.

  • How can I build a wrapper to wait for listening on a port?

    - by BillyBBone
    Hi, I am looking for a way of programmatically testing a script written with the asyncore Python module. My test consists of launching the script in question -- if a TCP listen socket is opened, the test passes. Otherwise, if the script dies before getting to that point, the test fails. The purpose of this is knowing if a nightly build works (at least up to a point) or not. I was thinking the best way to test would be to launch the script in some kind of sandbox wrapper which waits for a socket request. I don't care about actually listening for anything on that port, just intercepting the request and using that as an indication that my test passed. I think it would be preferable to intercept the open socket request, rather than polling at set intervals (I hate polling!). But I'm a bit out of my depths as far as how exactly to do this. Can I do this with a shell script? Or perhaps I need to override the asyncore module at the Python level? Thanks in advance, - B

    I have been looking for an answer for almost a week now, but having read all the stackoverflow items i can't seem to find a solution that is working for me. The error that i'm having is : Port: Could not establish connection. Receiving end does not exist. lastError:30 set lastError:30 dispatchOnDisconnect messaging:277 folder layout : img developer_icon.png js sidebar.js main.js jquery-2.0.3.js manifest.json my the manifest.json file looks something like this (it is version 2) :` "browser_action": { "default_icon": "./img/developer_icon.png" }, "content_scripts": [ { "matches": ["*://*/*"], "js": ["./js/sidebar.js"], "run_at": "document_end" } ], "background" : { "scripts" : ["./js/main.js","./js/jquery-2.0.3.js"] }, I want to handle the user clicking the extension icon so i could inject a sidebar in the existing website (because the extension i would like to develop requires that amount of space). So in main.js : chrome.browserAction.onClicked.addListener(function(tab) { chrome.tabs.getSelected(null, function(tab){ chrome.tabs.sendMessage( //Selected tab id tab.id, //Params inside a object data {callFunction: "toggleSidebar"}, //Optional callback function function(response) { console.log(response); } ); }); }); and in sidebar.js : chrome.runtime.onMessage.addListener(function(req,sender,sendResponse){ console.log("sidebar handling request"); toggleSidebar(); }); but i'm never able to see the console.log in my console because of the error. Does someone know what i did wrong? Thanks in advance!
