  • Why do I get 'Connection refused - connect(2)' for some models?

    - by Will
    I have a rails application running for the past 90 days that suddenly stopped working. Debugging the problem I found that I can read from the DB but not write to it. At least for certain models. There is one model that I can save whereas all others return Connection refused - connect(2) when I attempt to save them. They all used to work fine last month. I have no idea how to determine what the problem may be. Unfortunately I do not have access to the actual server remotely right now so I am limited in my debugging ability. I was able to get some non-tech people to run simple commands though that may help identify my problem. I will also be getting access tomorrow at some point. 1 Check from the console ./script/console >> a = Post.last.clone => #<Post id: nil, title: "test"... >> a.ex_id = 7 >> a.save Connection refused - connect(2) ... ... >> b = Story.last.console => #<Story id: nil, title: "test"... >> a.ex_id = 7 >> a.save => true I am not sure why this works for story and not post. This is consistent over many tests. 2 Check from mysql ./script/dbconsole -p mysql> INSERT INTO Posts (`title`,`body`, `ex_id`) SELECT `title`, `body`, 7 FROM Posts WHERE ID = 1; Query OK, 1 row affected (0.01 sec) Records: 1 Duplicates: 0 Warnings: 0 And as you can see I am able to write to the table with the same credientials that Rails uses? Does anyone know why I get connection refused in the console?

  • Apache mod_proxy_ajp and tomcat7 (TomEE). Telnet 8009 from localhost works, but from other machine connection refused

    - by exabrial
    In my tomcat config, I have the following: <!-- Define an AJP 1.3 Connector on port 8009 --> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> Once I start tomcat, on that same box, I can telnet localhost 8009 and get a connection. However, on the load balancer, I cannot telnet to that port. I've disabled the firewalls on both boxes. I'm able to connect on port 8080. What gives???

  • Oracle Announces Release of PeopleSoft HCM 9.1 Feature Pack 2

    - by Jay Zuckert
    Big things sometimes come in small packages.  Today Oracle announced the availability of PeopleSoft HCM 9.1 Feature Pack 2 which delivers a new HR self service user experience that fundamentally changes the way managers and employees interact with the HCM system.  Earlier this year we reviewed a number of new concept designs with our Customer Advisory Boards.  With the accelerated feature pack development cycle we have adopted, these innovations are  now available to all 9.1 customers without the need for an upgrade.   There are no new products that need to be licensed for the capabilities below. For more details on Feature Pack 2, please see the Oracle press release. Included in Feature Pack 2 is a new search-based menu-free navigation that allows managers to search for employees by name and take actions directly from the secure search results.  For example, a manager can now simply type in part of an employee’s first or last name and receive meaningful results from documents related to performance, compensation, learning, recruiting, career planning and more.   Delivered actions can be initiated directly from these search results and the actions are securely tied to HCM security and user role.  The feature pack also includes new pages that will enable managers to be more productive by aggregating key employee data into a single page.  The new Manager Dashboard and Talent Summary provide a consolidated view of data related to a manager’s team and individual team members, respectively.   The Manager Dashboard displays information relevant to their direct reports including team learning, objective alignment, alerts, and pending approvals requiring their attention.  The Talent Summary provides managers with an aggregated view of talent management-related data for an individual employee including performance history, salary history, succession options, total rewards, and competencies.   The information displayed in both the Manager Dashboard and Talent Summary is configurable by system administrators and can be personalized by each of your managers. Other Feature Pack 2 enhancements allow organizations to administer Matrix or Dotted-Line Relationship Management, which addresses the challenge of tracking and maintaining project-based organizations that cut across the enterprise and geographic regions.  From within the Company Directory and Org Viewer organization charts, managers now have access to manager self-service transactions from related actions.  More than 70 manager and employee self-service transactions have been tied into the related action framework accessible from Org Viewer, Manager Dashboard, Talent Summary and Secure Enterprise Search (SES) results.  In addition to making it easier to access manager self-service transactions, the feature pack delivers streamlined transaction pages making everyday tasks such as promoting an employee faster and more efficient. With the delivery of PeopleSoft HCM 9.1 Feature Pack 2, Oracle continues to deliver on its commitment to our PeopleSoft customers.  With this feature pack, HCM 9.1 customers will be able to deploy the newest functionality quickly, without a major release upgrade, and realize added value from their existing PeopleSoft investment.    For customers newly deploying 9.1, a new download with all of Feature Pack 2  will be available early next year.   This will aslo include recertified upgrade paths from 8.8, 8.9 and 9.0, for customers in the upgrade process.

  • WebLogic Server Performance and Tuning: Part II - Thread Management

    - by Gokhan Gungor
    WebLogic Server, like any other java application server, provides resources so that your applications use them to provide services. Unfortunately none of these resources are unlimited and they must be managed carefully. One of these resources is threads which are pooled to provide better throughput and performance along with the fast response time and to avoid deadlocks. Threads are execution points that WebLogic Server delivers its power and execute work. Managing threads is very important because it may affect the overall performance of the entire system. In previous releases of WebLogic Server 9.0 we had multiple execute queues and user defined thread pools. There were different queues for different type of work which had fixed number of execute threads.  Tuning of this thread pools and finding the proper number of threads was time consuming which required many trials. WebLogic Server 9.0 and the following releases use a single thread pool and a single priority-based execute queue. All type of work is executed in this single thread pool. Its size (thread count) is automatically decreased or increased (self-tuned). The new “self-tuning” system simplifies getting the proper number of threads and utilizing them.Work manager allows your applications to run concurrently in multiple threads. Work manager is a mechanism that allows you to manage and utilize threads and create rules/guidelines to follow when assigning requests to threads. We can set a scheduling guideline or priority a request with a work manager and then associate this work manager with one or more applications. At run-time, WebLogic Server uses these guidelines to assign pending work/requests to execution threads. The position of a request in the execute queue is determined by its priority. There is a default work manager that is provided. The default work manager should be sufficient for most applications. However there can be cases you want to change this default configuration. Your application(s) may be providing services that need mixture of fast response time and long running processes like batch updates. However wrong configuration of work managers can lead a performance penalty while expecting improvement.We can define/configure work managers at;•    Domain Level: config.xml•    Application Level: weblogic-application.xml •    Component Level: weblogic-ejb-jar.xml or weblogic.xml(For a specific web application use weblogic.xml)We can use the following predefined rules/constraints to manage the work;•    Fair Share Request Class: Specifies the average thread-use time required to process requests. The default is 50.•    Response Time Request Class: Specifies a response time goal in milliseconds.•    Context Request Class: Assigns request classes to requests based on context information.•    Min Threads Constraint: Limits the number of concurrent threads executing requests.•    Max Threads Constraint: Guarantees the number of threads the server will allocate to requests.•    Capacity Constraint: Causes the server to reject requests only when it has reached its capacity. Let’s create a work manager for our application for a long running work.Go to WebLogic console and select Environment | Work Managers from the domain structure tree. Click New button and select Work manager and click next. Enter the name for the work manager and click next. Then select the managed server instances(s) or clusters from available targets (the one that your long running application is deployed) and finish. Click on MyWorkManager, and open the Configuration tab and check Ignore Stuck Threads and save. This will prevent WebLogic to tread long running processes (that is taking more than a specified time) as stuck and enable to finish the process.

  • I.T. Chargeback : Core to Cloud Computing

    - by Anand Akela
    Contributed by Mark McGill Consolidation and Virtualization have been widely adopted over the years to help deliver benefits such as increased server utilization, greater agility and lower cost to the I.T. organization. These are key enablers of cloud, but in themselves they do not provide a complete cloud solution. Building a true enterprise private cloud involves moving from an admin driven world, where the I.T. department is ultimately responsible for the provisioning of servers, databases, middleware and applications, to a world where the consumers of I.T. resources can provision their infrastructure, platforms and even complete application stacks on demand. Switching from an admin-driven provisioning model to a user-driven model creates some challenges. How do you ensure that users provisioning resources will not provision more than they need? How do you encourage users to return resources when they have finished with them so that others can use them? While chargeback has existed as a concept for many years (especially in mainframe environments), it is the move to this self-service model that has created a need for a new breed of chargeback applications for cloud. Enabling self-service without some form of chargeback is like opening a shop where all of the goods are free. A successful chargeback solution will be able to allocate the costs of shared I.T. infrastructure based on the relative consumption by the users. Doing this creates transparency between the I.T. department and the consumers of I.T. When users are able to understand how their consumption translates to cost they are much more likely to be prudent when it comes to their use of I.T. resources. This also gives them control of their I.T. costs, as moderate usage will translate to a lower charge at the end of the month. Implementing Chargeback successfully create a win-win situation for I.T. and the consumers. Chargeback can help to ensure that I.T. resources are used for activities that deliver business value. It also improves the overall utilization of I.T. infrastructure as I.T. resources that are not needed are not left running idle. Enterprise Manager 12c provides an integrated metering and chargeback solution for Enterprise Manager Targets. This solution is built on top of the rich configuration and utilization information already available in Enterprise Manager. It provides metering not just for virtual machines, but also for physical hosts, databases and middleware. Enterprise Manager 12c provides metering based on the utilization and configuration of the following types of Enterprise Manager Target: Oracle VM Host Oracle Database Oracle WebLogic Server Using Enterprise Manager Chargeback, administrators are able to create a set of Charge Plans that are used to attach prices to the various metered resources. These plans can contain fixed costs (eg. $10/month/database), configuration based costs (eg. $10/month if OS is Windows) and utilization based costs (eg. $0.05/GB of Memory/hour) The self-service user provisioning these resources is then able to view a report that details their usage and helps them understand how this usage translates into cost. Armed with this information, the user is able to determine if the resources are delivering adequate business value based on what is being charged. Figure 1: Chargeback in Self-Service Portal Enterprise Manager 12c provides a variety of additional interfaces into this data. The administrator can access summary and trending reports. Summary reports allow the administrator to drill-down through the cost center hierarchy to identify, for example, the top resource consumers across the organization. Figure 2: Charge Summary Report Trending reports can be used for I.T. planning and budgeting as they show utilization and charge trends over a period of time. Figure 3: CPU Trend Report We also provide chargeback reports through BI Publisher. This provides a way for users who do not have an Enterprise Manager login (such as Line of Business managers) to view charge and usage information. For situations where a bill needs to be produced, chargeback can be integrated with billing applications such as Oracle Billing and Revenue Management (BRM).

  • When importing an Access table into Excel, a look-up column is showing all values as numbers

    - by user3651997
    I have a basic Access to Excel question that has me frustrated. I have two Access 2010 data tables. One is a list of managers. The primary key is a manager ID (which is an autonumber because managers can have the same name), and each row also has manager name, manager email, etc. The second data table is a list of departments. The primary key for each row is a unique department code, and the foreign key is a manager ID (autonumber). I used the Look-up Wizard to create this connection. However, Access does not show the manager ID in the foreign key location. It shows Manager Name like I requested when I used the Look-up Wizard. Now I am trying to import the second table (departments) into Excel 2010. I clicked import from Access, chose the Department table, and everything popped into Excel. BUT, the Manager Name column is showing Manager ID instead. So I have a list of numbers instead of names. How can I make Excel show what I see in Access? Thanks!

  • PHP - static DB class vs DB singleton object

    - by Marco Demaio
    I don't want to create a discussion about singleton better than static or better than global, etc. I read dozens of questions about it on SO, but I couldn't come up with an answer to this SPECIFIC question, so I hope someone could now illuminate me buy answering this question with one (or more) real simple EXAMPLES, and not theoretical discussions. In my app I have the typical DB class needed to perform tasks on DB without having to write everywhere in code mysql_connect/mysql_select_db/mysql... (moreover in future I might decide to use another type of DB engine in place of mySQL so obviously I need a class of abstration). I could write the class either as a static class: class DB { private static $connection = FALSE; //connection to be opened //DB connection values private static $server = NULL; private static $usr = NULL; private static $psw = NULL; private static $name = NULL; public static function init($db_server, $db_usr, $db_psw, $db_name) { //simply stores connections values, withour opening connection } public static function query($query_string) { //performs query over alerady opened connection, if not open, it opens connection 1st } ... } or as a Singletonm class: class DBSingleton { private $inst = NULL; private $connection = FALSE; //connection to be opened //DB connection values private $server = NULL; private $usr = NULL; private $psw = NULL; private $name = NULL; public static function getInstance($db_server, $db_usr, $db_psw, $db_name) { //simply stores connections values, withour opening connection if($inst === NULL) $this->inst = new DBSingleton(); return $this->inst; } private __construct()... public function query($query_string) { //performs query over already opened connection, if connection is not open, it opens connection 1st } ... } Then after in my app if I wanto to query the DB i could do //Performing query using static DB object DB:init(HOST, USR, PSW, DB_NAME); DB::query("SELECT..."); //Performing query using DB singleton $temp = DBSingleton::getInstance(HOST, USR, PSW, DB_NAME); $temp->query("SELECT..."); My simple brain sees Singleton has got the only advantage to avoid declaring as 'static' each method of the class. I'm sure some of you could give me an EXAMPLE of real advantage of singleton in this specific case. Thanks in advance.

  • WLS MBeans

    - by Jani Rautiainen
    WLS provides a set of Managed Beans (MBeans) to configure, monitor and manage WLS resources. We can use the WLS MBeans to automate some of the tasks related to the configuration and maintenance of the WLS instance. The MBeans can be accessed a number of ways; using various UIs and programmatically using Java or WLST Python scripts.For customization development we can use the features to e.g. manage the deployed customization in MDS, control logging levels, automate deployment of dependent libraries etc. This article is an introduction on how to access and use the WLS MBeans. The goal is to illustrate the various access methods in a single article; the details of the features are left to the linked documentation.This article covers Windows based environment, steps for Linux would be similar however there would be some differences e.g. on how the file paths are defined. MBeansThe WLS MBeans can be categorized to runtime and configuration MBeans.The Runtime MBeans can be used to access the runtime information about the server and its resources. The data from runtime beans is only available while the server is running. The runtime beans can be used to e.g. check the state of the server or deployment.The Configuration MBeans contain information about the configuration of servers and resources. The configuration of the domain is stored in the config.xml file and the configuration MBeans can be used to access and modify the configuration data. For more information on the WLS MBeans refer to: Understanding WebLogic Server MBeans WLS MBean reference Java Management Extensions (JMX)We can use JMX APIs to access the WLS MBeans. This allows us to create Java programs to configure, monitor, and manage WLS resources. In order to use the WLS MBeans we need to add the following library into the class-path: WL_HOME\lib\wljmxclient.jar Connecting to a WLS MBean server The WLS MBeans are contained in a Mbean server, depending on the requirement we can connect to (MBean Server / JNDI Name): Domain Runtime MBean Server weblogic.management.mbeanservers.domainruntime Runtime MBean Server weblogic.management.mbeanservers.runtime Edit MBean Server weblogic.management.mbeanservers.edit To connect to the WLS MBean server first we need to create a map containing the credentials; Hashtable<String, String> param = new Hashtable<String, String>(); param.put(Context.SECURITY_PRINCIPAL, "weblogic");        param.put(Context.SECURITY_CREDENTIALS, "weblogic1");        param.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES, "weblogic.management.remote"); These define the user, password and package containing the protocol. Next we create the connection: JMXServiceURL serviceURL =     new JMXServiceURL("t3","127.0.0.1",7101,     "/jndi/weblogic.management.mbeanservers.domainruntime"); JMXConnector connector = JMXConnectorFactory.connect(serviceURL, param); MBeanServerConnection connection = connector.getMBeanServerConnection(); With the connection we can now access the MBeans for the WLS instance. For a complete example see Appendix A of this post. For more details refer to Accessing WebLogic Server MBeans with JMX Accessing WLS MBeans The WLS MBeans are structured hierarchically; in order to access content we need to know the path to the MBean we are interested in. The MBean is accessed using “MBeanServerConnection. getAttribute” API.  WLS provides entry points to the hierarchy allowing us to navigate all the WLS MBeans in the hierarchy (MBean Server / JMX object name): Domain Runtime MBean Server com.bea:Name=DomainRuntimeService,Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean Runtime MBean Servers com.bea:Name=RuntimeService,Type=weblogic.management.mbeanservers.runtime.RuntimeServiceMBean Edit MBean Server com.bea:Name=EditService,Type=weblogic.management.mbeanservers.edit.EditServiceMBean For example we can access the Domain Runtime MBean using: ObjectName service = new ObjectName( "com.bea:Name=DomainRuntimeService," + "Type=weblogic.management.mbeanservers.domainruntime.DomainRuntimeServiceMBean"); Same syntax works for any “child” WLS MBeans e.g. to find out all application deployments we can: ObjectName domainConfig = (ObjectName)connection.getAttribute(service,"DomainConfiguration"); ObjectName[] appDeployments = (ObjectName[])connection.getAttribute(domainConfig,"AppDeployments"); Alternatively we could access the same MBean using the full syntax: ObjectName domainConfig = new ObjectName("com.bea:Location=DefaultDomain,Name=DefaultDomain,Type=Domain"); ObjectName[] appDeployments = (ObjectName[])connection.getAttribute(domainConfig,"AppDeployments"); For more details refer to Accessing WebLogic Server MBeans with JMX Invoking operations on WLS MBeans The WLS MBean operations can be invoked with MBeanServerConnection. invoke API; in the following example we query the state of “AppsLoggerService” application: ObjectName appRuntimeStateRuntime = new ObjectName("com.bea:Name=AppRuntimeStateRuntime,Type=AppRuntimeStateRuntime"); Object[] parameters = { "AppsLoggerService", "DefaultServer" }; String[] signature = { "java.lang.String", "java.lang.String" }; String result = (String)connection.invoke(appRuntimeStateRuntime,"getCurrentState",parameters, signature); The result returned should be "STATE_ACTIVE" assuming the "AppsLoggerService" application is up and running. WebLogic Scripting Tool (WLST) The WebLogic Scripting Tool (WLST) is a command-line scripting environment that we can access the same WLS MBeans. The tool is located under: $MW_HOME\oracle_common\common\bin\wlst.bat Do note that there are several instances of the wlst script under the $MW_HOME, each of them works, however the commands available vary, so we want to use the one under “oracle_common”. The tool is started in offline mode. In offline mode we can access and manipulate the domain configuration. In online mode we can access the runtime information. We connect to the Administration Server : connect("weblogic","weblogic1", "t3://127.0.0.1:7101") In both online and offline modes we can navigate the WLS MBean using commands like "ls" to print content and "cd" to navigate between objects, for example: All the commands available can be obtained with: help('all') For details of the tool refer to WebLogic Scripting Tool and for the commands available WLST Command and Variable Reference. Also do note that the WLST tool can be invoked from Java code in Embedded Mode. Running Scripts The WLST tool allows us to automate tasks using Python scripts in Script Mode. The script can be manually created or recorded by the WLST tool. Example commands of recording a script: startRecording("c:/temp/recording.py") <commands that we want to record> stopRecording() We can run the script from WLST: execfile("c:/temp/recording.py") We can also run the script from the command line: C:\apps\Oracle\Middleware\oracle_common\common\bin\wlst.cmd c:/temp/recording.py There are various sample scripts are provided with the WLS instance. UI to Access the WLS MBeans There are various UIs through which we can access the WLS MBeans. Oracle Enterprise Manager Fusion Middleware Control Oracle WebLogic Server Administration Console Fusion Middleware Control MBean Browser In the integrated JDeveloper environment only the Oracle WebLogic Server Administration Console is available to us. For more information refer to the documentation, one noteworthy feature in the console is the ability to record WLST scripts based on the navigation. In addition to the UIs above the JConsole included in the JDK can be used to access the WLS MBeans. The JConsole needs to be started with specific parameter to force WLS objects to be used and jar files in the classpath: "C:\apps\Oracle\Middleware\jdk160_24\bin\jconsole" -J-Djava.class.path=C:\apps\Oracle\Middleware\jdk160_24\lib\jconsole.jar;C:\apps\Oracle\Middleware\jdk160_24\lib\tools.jar;C:\apps\Oracle\Middleware\wlserver_10.3\server\lib\wljmxclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote For more details refer to the Accessing Custom MBeans from JConsole.

  • Timeout Considerations for Solicit Response – Part 2

    - by Michael Stephenson
    To follow up a previous article about timeouts and how they can affect your application I have extended the sample we were using to include WCF. I will execute some test scenarios and discuss the results. The sample We begin by consuming exactly the same web service which is sitting on a remote server. This time I have created a .net 3.5 application which will consume the web service using the basichttp binding. To show you the configuration for the consumption of this web service please refer to the below diagram. You can see like before we also have the connectionManagement element in the configuration file. I have added a WCF service reference (also using the asynchronous proxy methods) and have the below code sample in the application which will asynchronously make the web service calls and handle the responses on a call back method invoked by a delegate. If you have read the previous article you will notice that the code is almost the same.   Sample 1 – WCF with Default Timeouts In this test I set about recreating the same scenario as previous where we would run the test but this time using WCF as the messaging component. For the first test I would use the default configuration settings which WCF had setup when we added a reference to the web service. The timeout values for this test are: closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"   The Test We simulated 21 calls to the web service Test Results The client-side trace is as follows:   The server-side trace is as follows: Some observations on the results are as follows: The timeouts happened quicker than in the previous tests because some calls were timing out before they attempted to connect to the server The first few calls that timed out did actually connect to the server and did execute successfully on the server   Test 2 – Increase Open Connection Timeout & Send Timeout In this test I wanted to increase both the send and open timeout values to try and give everything a chance to go through. The timeout values for this test are: closeTimeout="00:01:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"   The Test We simulated 21 calls to the web service   Test Results The client side trace for this test was   The server-side trace for this test was: Some observations on this test are: This test proved if the timeouts are high enough everything will just go through   Test 3 – Increase just the Send Timeout In this test we wanted to increase just the send timeout. The timeout values for this test are: closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"   The Test We simulated 21 calls to the web service   Test Results The below is the client side trace The below is the server side trace Some observations on this test are: In this test from both the client and server perspective everything ran through fine The open connection timeout did not seem to have any effect   Test 4 – Increase Just the Open Connection Timeout In this test I wanted to validate the change to the open connection setting by increasing just this on its own. The timeout values for this test are: closeTimeout="00:01:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"   The Test We simulated 21 calls to the web service Test Results The client side trace was The server side trace was Some observations on this test are: In this test you can see that the open connection which relates to opening the channel timeout increase was not the thing which stopped the calls timing out It's the send of data which is timing out On the server you can see that the successful few calls were fine but there were also a few calls which hit the server but timed out on the client You can see that not all calls hit the server which was one of the problems with the WSE and ASMX options   Test 5 – Smaller Increase in Send Timeout In this test I wanted to make a smaller increase to the send timeout than previous just to prove that it was the key setting which was controlling what was timing out. The timeout values for this test are: openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:02:30"   The Test We simulated 21 calls to the web service Test Results The client side trace was   The server side trace was Some observations on this test are: You can see that most of the calls got through fine On the client you can see that call 20 timed out but still hit the server and executed fine.   Summary At this point between the two articles we have quite a lot of scenarios showing the different way the timeout setting have played into our original performance issue, and now we can see how WCF could offer an improved way to handle the problem. To summarise the differences in the timeout properties for the three technology stacks: ASMX The timeout value only applies to the execution time of your request on the server. The timeout does not consider how long your code might be waiting client side to get a connection. WSE The timeout value includes both the time to obtain a connection and also the time to execute the request. A timeout will not be thrown as an error until an attempt to connect to the server is made. This means a 40 second timeout setting may not throw the error until 60 seconds when the connection to the server is made. If the connection to the server is made you should be aware that your message will be processed and you should design for this. WCF The WCF send timeout is the setting most equivalent to the settings we were looking at previously. Like WSE this setting the counter includes the time to get a connection as well as the time to execute on a server. Unlike WSE and ASMX an error will be thrown as soon as the send timeout from making your call from user code has elapsed regardless of whether we are waiting for a connection or have an open connection to the server. This may to a user appear to have better latency in getting an error response compared to WSE or ASMX.

  • Plymouth did not install properly

    - by David Starkey
    I was installing the plymouth manager in hopes of making a custom loading screen. While the terminal was working, my computer unexpectedly powered off. I can open up the manager and it appears to do what it is supposed to (minus the fact that I can't make my own theme) and the screen only shows on powering down. Anyway, all of the advice I have seen so far have resulted in errors and nothing getting fixed. I do not have permissions to simply select the folder and delete it for some reason and I have not been able to find out how to grant myself those permissions. I guess my question then is how do I get rid of the plymouth manager so I can reinstall it properly? Already tried: -Installation - http://www.noobslab.com/2011/11/install-plymouth-manager-and-change.html -Removal - How to remove Plymouth Boot Animation manager and keep the default boot screen -Permissions - How do I change my user permissions to edit /etc/apt/sources.list? -Theming Guide - http://brej.org/blog/?p=158

  • Facing issues in setting up VPN connection(IKEv1) using iphone (Defult Cisco VPN client) and Strongswan 4.5.0 server

    - by Kushagra Bhatnagar
    I am facing issues in setting up VPN connection(IKEv1) using iPhone (Defult Cisco VPN client) and Strongswan 4.5.0 server. The Strongswan server is running on Ubuntu Linux, which is connected to some wifi hotspot. This is the guide which was used. I generated CA, server and client certificate, with the only difference mentioned below. “While generating server certificate, as per link CN=vpn.strongswan.org instead of this I changed CN name to CN=192.168.43.212.” Once certificates are generated, following (clientCert.p12 and caCert.pem) are sent to mobile via mail and installed on iphone. After installation I notice that certificates are considered as trusted also. Below are the ip addresses assigned to various interfaces Linux server wlan0 interface ip where server is running: 192.168.43.212 Iphone eth0 interface ip address: 192.168.43.72. iphone is also attached with the same wifi hotspot. Below is the snapshot of client configurations. Description Strong swan Server 192.168.43.212 Account ipsecvpn Password ***** Use certificate ON Certificate client The above username and password are in sync with the ipsec.secrets file. I am using the following ipsec.conf configuration: # basic configuration config setup plutodebug=all # crlcheckinterval=600 # strictcrlpolicy=yes # cachecrls=yes nat_traversal=yes # charonstart=yes plutostart=yes # Add connections here. # Sample VPN connections conn ios1 keyexchange=ikev1 authby=xauthrsasig xauth=server left=%defaultroute leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=192.168.43.72 rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem pfs=no auto=add With the above configurations when I enable VPN on iphone, it says Could not able to verify server certificate. I ran Wireshark on a Linux server and observe that initially some ISAKMP message exchanges happens between client and server, which are successful but before authorization, client is sending some informational message and soon after this client is showing error as popup Could not able to verify server certificate. Capture logs on Strongswan server and in server logs below errors are observed: From auth.log Apr 25 20:16:08 Linux pluto[4025]: | ISAKMP version: ISAKMP Version 1.0 Apr 25 20:16:08 Linux pluto[4025]: | exchange type: ISAKMP_XCHG_INFO Apr 25 20:16:08 Linux pluto[4025]: | flags: ISAKMP_FLAG_ENCRYPTION Apr 25 20:16:08 Linux pluto[4025]: | message ID: 9d 1a ea 4d Apr 25 20:16:08 Linux pluto[4025]: | length: 76 Apr 25 20:16:08 Linux pluto[4025]: | ICOOKIE: f6 b7 06 b2 b1 84 5b 93 Apr 25 20:16:08 Linux pluto[4025]: | RCOOKIE: 86 92 a0 c2 a6 2f ac be Apr 25 20:16:08 Linux pluto[4025]: | peer: c0 a8 2b 48 Apr 25 20:16:08 Linux pluto[4025]: | state hash entry 8 Apr 25 20:16:08 Linux pluto[4025]: | state object not found Apr 25 20:16:08 Linux pluto[4025]: **packet from 192.168.43.72:500: Informational Exchange is for an unknown (expired?)

  • USB connection is unstable with Nexus S 2.3.4 on AMD 64 running 64-bit Windows 7, but works with 32-bit Windows Vista

    - by Mike
    The USB connection is unstable with Nexus S (Android 2.3.4) on AMD 64 running 64-bit Windows 7, but it works with 32-bit Windows Vista. Problem Description: On the 64-bit Windows 7 machine my Nexus S appears to connect, but then it disconnects moments later. Neither accessing USB storage or loading an Android application package file (APK) using the Android Debug Bridge (ADB) work. On 32-bit Windows Vista using the same USB cable, USB storage works. I haven't tried the ADB on 32-bit Windows Vista. Reproduction steps for USB storage: (I have provided the reproduction steps for USB storage and not ADB, because if one isn't working, then the other isn't working either and the USB storage reproduction steps are shorter to document.) Connect the USB cable to the Nexus S and my Windows 7 machine. Effect: The "USB Mass Storage, USB Connected" dialog appears with the button "Turn on USB storage." Click "Turn on USB Storage" Effect: The "working circle" appears. A dialog briefly appears saying "USB storage in use," then it either returns me to Step 1 (now that I am running 2.3.4) or is replaced with the Nexus S's application homepage (while I was running 2.3.3). I'm not sure if the version matters, but I mention it for completeness. On the 32-bit Windows Vista machine the connection is stable. I am able to navigate through the Nexus S file system create, read, update, and delete files, etc. I haven't tried connecting with the ADB. Troubleshooting summary: Tried and failed: Uninstalling and reinstalling the Android USB drivers including removing the files. Uninstalling my custom software Pulling the Nexus S's battery Restarting the Nexus S Restarting 64-bit Windows 7 Changing USB ports on the 64-bit Windows 7 box Compared the dates and file size on the DLLs in my google-usb_driver\amd64 directory and the windows\System32 directory. They match. The sizes for the google-usb_driver\i386 directory do not match (expected). Turning off Debugging mode on the Nexus S does not resolve the problem. Searching Google. Tried and succeeded: Connecting to another machine (Windows Vista) using the same USB cable and Nexus S phone. Troubleshooting observations: I notice that uninstalling the device drivers and deleting the files, then reinstalling the drivers, then rebooting 64-bit Windows 7 then unplugging the Nexus S, then plugging it back in occasionally helps for a short amount of time (minutes to hours, not days). When it is working, I can both access the Nexus S's drive and load/test applications using the ADB. I have observed some wonky behavior in the Device Manager that I haven't tracked down. Sometimes the black Nexus S image appears in the list of devices. Sometimes the image displays as a computer with a green ISA card. Sometimes it neither appears on the top level of devices nor under “other devices,” but it does appear under "disk drives" as "Android UMS Composite USB Device." System configuration: The Nexus S is running Android OS 2.3.4's "Settings\about phone\System updates" indicates that it is up to date as of May 21st 2011. Both 32-bit Windows Vista and 64-bit Windows 7 are up to date. The Windows Vista system is running on an Intel 32-bit processor. Windows 7 is running on an AMD 64-bit processor. I have done Android development on both systems, but I usually develop on the 64-bit Windows 7 machine.

  • Continual "The Windows Filtering Platform has blocked a connection" errors?

    - by Richard
    Our systems have been compromised by something recently which has lead us to carry out a more detailed look at what is happening on our workstations. I have noticed an issue where the Security log of this Windows 7 workstation is continually logging a security "Audit Failure" where the detail is that "The Windows Filtering Platform has blocked a connection". This is happening thousands of times a day and would appear to be our BT Business Broadband HGV 2700 ADSL router attempting to connect to Port 137 (NET Bios) on my workstation and being blocked. This has unfortunately had the effect of filling up the log files so much that anything which might have been of use which was logged over the weekend to help debug the intrusion has been "overwritten off the end" of the Security log. (I've since increased the log file size limits massively and turned on archiving). Does anyone know if this is standard behaviour of a BT ADSL router or whether this indicates that the router is compromised in some way or malfunctioning, or have any further suggestions as to how to diagnose this problem?

  • Exchange 2010 periodically stops responding to SMTP events with error 421 4.4.1 Connection timed out

    - by Michael Shimmins
    After some help diagnosing why Exchange 2010 Enterprise stops responding to SMTP events. I can't find a pattern to it. It doesn't appear to be an actual timeout, as the server responds immediately with the error. To reproduce it I telnet into the server on port 25 and issue a EHLO. The server immediately replies with the 421: 421 4.4.1 Connection timed out Once this starts happening I've found restarting the exchange box is the only reliable way to get it flowing again. Sometimes restarting the Transport service or the mailbox attendant service seems to fix it, but this could be coincidental as it often has no effect.

  • Unable to make admin interface connection to server when moving a mailbox.

    - by TheCodeMonk
    I have an existing Exchange 2003 server running on Windows Server 2003. I am in the process of replacing our current server infrastructure and virtualizing it all in Hyper-V. I have Essential Business Server 2008 installed in 3 separate VMs and running. Everything seems to be working fine so far. I am now trying to migrate my exchange mailboxes over to the new exchange server in the messaging server and every time I try I get this error: MapiExceptionNetworkError: Unable to make admin interface connection to server. (hr=0x80040115, ec=-2147221227) I have done some searching and found solutions like adding the computer to the exchange domain servers groups and install group, also making sure the user logged into the new server is in the proper groups. I also saw a solution in making sure that any unused NICs are disabled. I've tried all that to no avail.

  • Enable Php Fastcgi and Get 500 Internal Server Error (Lighttpd)

    - by skycrew
    anyone can help me? I just got this problem today. Before this my site running smooth with Fastcgi enable but now its show 500 internal server error with below logs.

  • How can Bonjour be setup to function over a VPN connection using Mac OS X — Mountain Lion Server?

    - by Ben Coppock
    I purchased Mountain Lion Server for our office thinking that Bonjour would automatically enable any computers connected via VPN to see all computers and applications (such as Bento) running on the office network. The hope was that those of us working at home would feel just like we were in the office, with all network services working transparently over the VPN connection. However, I see that Bonjour (aka mDNS) is not enabled to work over the VPN by default. Can I configure Mountain Lion Server to automatically pass Bonjour traffic over the VPN? Is there any reason not to do this?

  • Bring internet connection to ssh target machine via tunnel?

    - by Calvin
    I have a CentOS 5 machine deep inside firewalls that's only reachable via ssh on an unconventional port, let's say 98765. I normally connect to this machine like this: ssh -P 98765 user@ip -L5900:localhost:5900 I need to run yum to install some packages on this machine, but it's not possible since the outbound ports are all closed on this machine. I want to do something like this to "bring my internet connection" to this machine: ssh -P 98765 user@ip -L5900:localhost:5900 -R80:localhost:80 -R21:localhost:21 My intention is that, when I run yum on the machine, yum will use port 80 and 21 through my originating machine. Is something like this even possible?

  • Can I setup a link SQL server connection between servers on different networks?

    - by Glenn Slaven
    We have a production SQL server hosted offsite at a hosting company, and we have a staging environment within our own network. We want to be able to setup a SQL job that copies content from a table on the staging server to prod on a regular basis, and I think we need to setup a linked server connection to do this. What do I need to get the hosting company to do to allow us to set this up? We have RDP access to the production servers, I just need to know what network and security configurations need to happen from the hosting company's perspective so I can ask them to do it.

  • How can I speed up my Windows Server 2008 VPN Connection?

    - by Pure.Krome
    So I've installed VPN service that comes with Windows Server 2008. Works perfectly, etc. When a client remote desktops to one of the private servers at the office, via VPN .. it's pretty slow. Now - how long is a piece of string? So before I get all the obligatory checks, I'll list the things from Mr. Obvious: Our modem/router (fritz!box) has a data/graph that shows incoming and outbound bandwidth. Both directions are barely getting used when a client has RDP'd via VPN. Our office internet connection is running at 21,9 Mbit/s download 1,3 Mbit/s upload. I feel like it's maxing at .. modem speeds ?? Is there any tricks I can do to confirm this and possibly even fix this?
