"This computer has dynamically assigned IP addresses" error when installing Active Directory Domain Controller

- by smhnaji

This is a working Windows Server 2008 that I should install Active Directory on it. I found http://www.howtogeek.com/99323/ and followed the steps. After Additional Domain Controller Options, I'm asked the question "This computer has dynamically assigned IP addresses". As I see, the message states that Dynamic IP addressing has been used for the server, while this is wrong. When I come to Network And Sharing Center, and click on Local Area Connections - Properties - Internet Protocol Version 4 (TCP/IPv4) - Properties, I see that the main IP address (as well as DNS Server) and also all other IP addresses are assigned statically. So it should be OK. I cannot believe any server using dynamic IP(s)! Note: No IPv6 has been set for the server. Please tell me why the error is given and which of the options available, should I choose? Note that it's a production server and is working with many users in WORKGROUP. No change should be affected nor to the IPs, neither to users connecting to the server.

Monitoring System for the cloud?

- by Maxim Veksler

I need a monitoring system, much like ganglia / nagios that is build for the cloud. I need it to support : Adding / removing nodes dynamically. (Node shuts down, dose not imply node failure...) Dynamic node based categorization, meaning node can identify them self as being part of group X (ganglia gets this almost right, but lacks the dynamic part...) Does not require multicast support (generally not allowed in cloud based setups) Plugins for recent cool stuff such as Hadoop, Cassandra, Mongo would be cool. More features include: External API, web interface and co. I've looked at Ganglia, munin and they both seem be almost there (but not exactly). I would also go for reasonably priced Software as Service solution. I'm currently doing research, so Suggestions are highly appreciated. Thank you, Maxim

How do I bind to something outside a datacontext.

- by AKRamkumar

I have a listbox in WPF that is in the Layout Root. I also have a Frame that is in the Layout Root as well. The listbox is composed of items that have a string(Name) and a framework element(UI). How do I bind the frame's content to be the UI property of the listbox's selected item property? If you need a codebehind, how would you do this in MVVM

ASP.NET AJAX Doesnt Work

I have a very simple AJAX example that doesn't work. It is from the Microsoft tutorials on AJAX. When I click on button "Button1" AJAX should execute but the whole page submits.

getting started with Google Closure if you don't care about minifying/compiling?

- by Tim

If you don't care about minifying your code, is there a way to get started using the Google Closure library without having to set up a subversion client and use the compiler? The Notepad sample program on Google's website refers to <script src="closure-library/base.js" > </script > Can you simply download closure-library/base.js somewhere and start playing with the UI examples? The Closure Lite quick-start version doesn't appear to include goog.ui

Can't access shared drive when connecting over VPN

- by evolvd

I can ping all network devices but it doesn't seem that DNS is resolving their hostnames. ipconfig/ all is showing that I am pointing to the correct dns server. I can "ping "dnsname"" and it will resolve but it wont resolve any other names. Split tunnel is set up so outside DNS is resolving fine So one issue might be DNS but I have the IP address of the server share so I figure I could just get to it that way. example: \10.0.0.1\ well I can't get to it that way either and I get "the specified network name is no longer available" I can ping it but I can't open the share.

faster ( squid + apache httpd + apache tomcat )

- by letronje

We have a production setup where we have Squid in the front(caching images, js, css, etc) Apache httpd in the middle(prefork + mod_rewrite + mod_jk/AJP + mod_deflate + mod_php(few php pages)) Apache tomcat 5.5 at the end serving all the dynamic stuff. What would be the best way to reduce the overhead of having 3 servers in the request path ? Wondering if replacing httpd with a faster web server like nginx/lighttpd will help. httpd right now does the job of url rewriting(for clean urls) and talking to tomcat(via mod_jk) and compressing output(mod_deflate) and serving some low traffic php pages. What would be ideal replacement for httpd given that we need these features? Is there a way to replace (squid + apache) with a single entity that does caching well (like squid) for static stuff, rewrites url, compresses response and forwards dynamic stuff directly to tomcat ? heard abt varnish cache, wondering if it can help.

Hi, All! I have some Qt application with QPlainTextEdit in Tab widget. When try to make a pointer on it QPlainTextEdit *w = (QPlainTextEdit*)ui->tabWidget->widget(0) and call a document() method w->document() I get a segfault. But if i call document directly, e.g. ui-mainEdit-document(), then everything works fine. Can anybody explain me why it happens?

Configure TCP/IP to use DHCP and a Static IP Address at the Same Time

- by Tiago

My computer is configured to obtain a IP address automatically using DHCP. It only has one network adapter. How to configure an additional static IP address? I found a tutorial for Windows XP, but the procedure didn't work for Windows 7. Is it possible to configure two IP addresses on Windows 7, one being static e another being dynamic? How? The dynamic address I got now is 10.17.11.162. The static IP is 10.17.30.19. The network mask is the same: 255.255.224.0. Both work independently, but I don't know how to use both at the same time.

SMTP hacked by spammer using base64 encoding to authenticate

- by Throlkim

Over the past day we've detected someone from China using our server to send spam email. It's very likely that he's using a weak username/password to access our SMTP server, but the problem is that he appears to be using base64 encoding to prevent us from finding out which account he's using. Here's an example from the maillog: May 5 05:52:15 195396-app3 smtp_auth: SMTP connect from (null)@193.14.55.59.broad.gz.jx.dynamic.163data.com.cn [59.55.14.193] May 5 05:52:15 195396-app3 smtp_auth: smtp_auth: SMTP user info : logged in from (null)@193.14.55.59.broad.gz.jx.dynamic.163data.com.cn [59.55.14.193] Is there any way to detect which account it is that he's using?

Specify debug/release build in qt

- by Royi Freifeld

I would like Qt Creator to build the project according to the type I specify in the little computer button. Using: CONFIG(debug, debug|release) { DESTDIR = Debug OBJECTS_DIR = Debug/.obj MOC_DIR = Debug/.moc RCC_DIR = Debug/.rcc UI_DIR = Debug/.ui } CONFIG(release, debug|release) { DESTDIR = Release OBJECTS_DIR = Release/.obj MOC_DIR = Release/.moc RCC_DIR = Release/.rcc UI_DIR = Release/.ui } Or, using the answer from here, makes qmake chose the last time a variable was defined. How do I set it? Thnx P.S I don't know if it has something to do with my problem, but I'm using Ubuntu and not Windows

How can I pass managed objects from one AppDomain to another?

- by Dennis P

I have two assemblies that I'm trying to link together. One is a sort of background process that's built with WinForms and will be designed to run as a Windows Service. I have a second project that will act as a UI for the background process whenever a user launches it. I've never tried attempting something like this with managed code before, so I've started trying to use windows messages to communicate between the two processes. I'm struggling when it comes to passing more than just IntPtrs back and forth, however. Here's the code from a control in my UI project that registers itself with the background process: public void Init() { IntPtr hwnd = IntPtr.Zero; Process[] ps = Process.GetProcessesByName("BGServiceApp"); Process mainProcess = null; if(ps == null || ps.GetLength(0) == 0) { mainProcess = LaunchApp(); } else { mainProcess = ps[0]; } SendMessage(mainProcess.MainWindowHandle, INIT_CONNECTION, this.Handle, IntPtr.Zero); } protected override void WndProc(ref Message m) { if(m.Msg == INIT_CONFIRMED && InitComplete != null) { string message = Marshal.PtrToStringAuto(m.WParam); Marshal.FreeHGlobal(m.WParam); InitComplete(message, EventArgs.Empty); } base.WndProc(ref m); } This is the code from the background process that's supposed to receive a request from the UI process to register for status updates and send a confirmation message. protected override void WndProc(ref Message m) { if(m.Msg == INIT_CONNECTION) { RegisterUIDispatcher(m.WParam); Respond(m.WParam); } if(m.Msg == UNINIT_CONNECTION) { UnregisterUIDispatcher(m.WParam); if(m_RegisteredDispatchers.Count == 0) { this.Close(); } } base.WndProc(ref m); } private void Respond(IntPtr caller) { string test = "Registration confirmed!"; IntPtr ptr = Marshal.StringToHGlobalAuto(test); SendMessage(caller, INIT_CONFIRMED, ptr, IntPtr.Zero); } } The UI process receives the INIT_CONFIRMED message from my background process, but when I try to marshal the IntPtr back into a string, I get an empty string. Is the area of heap I'm using out of scope to the other process or am I missing some security attribute maybe? Is there a better and cleaner way to go about something like this using an event driven model?

Web service not accessible from behind corporates firewalls - how come?

- by Niro

We run a Saas serving a widget which is embedded in customer websites. The service include static javascript code hosted on amazon S3 and dynamic part hosted on EC2 with Scalr (using scalr name servers). We received some feedback from users behind corporate firewalls that they cant access our service (while they can access the sites including the widget). This does not make sense to me since the service is using normal http calls on port 80 and our URL is quite new without any reason to be banned by firewalls. My questions are: 1. Why is the service is not accessible and what can I do about it? 2. Is it possible that one of the following is blocked by corporate firewalls: Amazon s3, the dynamic IP address provided by amazon, Scalr name servers. Any other possible reasons, way to check them and remedies for this? Thanks!

How to automatically resume php-fpm?

- by alfish

I am using nginx+php-fpm on Debian Squeeze for a busy server and have had great difficulty to deal with maximum connections being reached. Here the problem is that php processes sometimes just die randomly under high load and leave the server with no php process. Then I need to manually restart php5-fpm service to bring back the server to life. I am wondering how to avoid this to happen, or at least treat the symptoms by restarting the php5-fpm automatically whenever there is not php process left to listen to incoming requests. My relevant configs are: pm = dynamic pm.max_children = 1400 pm.start_servers = 10 pm.max_spare_servers = 20 pm.process_idle_timeout = 1s; #not sure it will be useful when pm=dynamic pm.max_requests = 100000 request_terminate_timeout = 30 I appreciate your suggestions to cope with this nasty problem.

iPhone Human Interface Guidelines question

iPhone Human Interface Guidelines -- Do they apply for OpenGL games? GL games typically have custom buttons, custom lists, etc. Take the Quake player list for example, if ported, it wouldnt be a typical UI list object. Does this mean the reviewer in question would reject anything that wasn't using standard UI? Or, is there an exception for games.

Languages and VMs: Features that are hard to optimize and why

- by mrjoltcola

I'm doing a survey of features in preparation for a research project. Name a mainstream language or language feature that is hard to optimize, and why the feature is or isn't worth the price paid, or instead, just debunk my theories below with anecdotal evidence. Before anyone flags this as subjective, I am asking for specific examples of languages or features, and ideas for optimization of these features, or important features that I haven't considered. Also, any references to implementations that prove my theories right or wrong. Top on my list of hard to optimize features and my theories (some of my theories are untested and are based on thought experiments): 1) Runtime method overloading (aka multi-method dispatch or signature based dispatch). Is it hard to optimize when combined with features that allow runtime recompilation or method addition. Or is it just hard, anyway? Call site caching is a common optimization for many runtime systems, but multi-methods add additional complexity as well as making it less practical to inline methods. 2) Type morphing / variants (aka value based typing as opposed to variable based) Traditional optimizations simply cannot be applied when you don't know if the type of someting can change in a basic block. Combined with multi-methods, inlining must be done carefully if at all, and probably only for a given threshold of size of the callee. ie. it is easy to consider inlining simple property fetches (getters / setters) but inlining complex methods may result in code bloat. The other issue is I cannot just assign a variant to a register and JIT it to the native instructions because I have to carry around the type info, or every variable needs 2 registers instead of 1. On IA-32 this is inconvenient, even if improved with x64's extra registers. This is probably my favorite feature of dynamic languages, as it simplifies so many things from the programmer's perspective. 3) First class continuations - There are multiple ways to implement them, and I have done so in both of the most common approaches, one being stack copying and the other as implementing the runtime to use continuation passing style, cactus stacks, copy-on-write stack frames, and garbage collection. First class continuations have resource management issues, ie. we must save everything, in case the continuation is resumed, and I'm not aware if any languages support leaving a continuation with "intent" (ie. "I am not coming back here, so you may discard this copy of the world"). Having programmed in the threading model and the contination model, I know both can accomplish the same thing, but continuations' elegance imposes considerable complexity on the runtime and also may affect cache efficienty (locality of stack changes more with use of continuations and co-routines). The other issue is they just don't map to hardware. Optimizing continuations is optimizing for the less-common case, and as we know, the common case should be fast, and the less-common cases should be correct. 4) Pointer arithmetic and ability to mask pointers (storing in integers, etc.) Had to throw this in, but I could actually live without this quite easily. My feelings are that many of the high-level features, particularly in dynamic languages just don't map to hardware. Microprocessor implementations have billions of dollars of research behind the optimizations on the chip, yet the choice of language feature(s) may marginalize many of these features (features like caching, aliasing top of stack to register, instruction parallelism, return address buffers, loop buffers and branch prediction). Macro-applications of micro-features don't necessarily pan out like some developers like to think, and implementing many languages in a VM ends up mapping native ops into function calls (ie. the more dynamic a language is the more we must lookup/cache at runtime, nothing can be assumed, so our instruction mix is made up of a higher percentage of non-local branching than traditional, statically compiled code) and the only thing we can really JIT well is expression evaluation of non-dynamic types and operations on constant or immediate types. It is my gut feeling that bytecode virtual machines and JIT cores are perhaps not always justified for certain languages because of this. I welcome your answers.

Hi All, While working in my application i came across a situation in which there are likely chances to Unque Constraints Violation.I have following options Catch the exception and throw it back to UI At UI check for the exception and show approrpriate Error Message This is something different idea is to Check in advance about the existance of the given Unique value before starting the whole operation. My Question is what might be the best practice to handle such situation.Currently we are using combo of Struts2+Spring 3.x+Hibernate 3.x Thanks in advance

Cross-Forest Trust

- by cdalley

I am looking at testing a cross-domain trust we can have two domain controllers (with different forests and domain names) setup so we can move everyone onto the new domain. We do NOT run exchange on site and we do not have any links to O365 to AD currently. Onto the problem: I have setup two DCs in a Virtual Machine: They are on the same network 192.168.0.* The Windows 2003 server: Name: OLDSRVR "Clone" of our current Domain Controller IP: 192.168.0.1 Domain: internal.test.com The Windows 2012 server: Name: ADCTEST01 Brand new domain setup from scratch separate to internal.test.com Domain: internal.test2.com IP: 192.168.0.2 OLDSRVR can only see ADCTEST if it has dynamic IP set. If I set a static IP it cannot see it. If I try using the dynamic IP and try to join it gets to the end then complains "??The trust relationship between this workstation and the primary domain failed" Any ideas?

save the transient instance before flushing

- by eugenn

Exception: object references an unsaved transient instance - save the transient instance before flushing: Child How to reproduce issue: 1. Hibernate is load the entity "Parent". The property "child" is null 2. The "Parent" is rendered on the screen and after that the "child" property is auto instantiated. So I have the following graph: Parent.child != null Parent.child.childId = null Parent.child.childKey = "" Parent.child.childName = "" Question: How I could to force the Hibernate to ignore updating or inserting Child entity WHEN childId = null? If childId != null I would like just create relation. <hibernate-mapping> <class name="com.test.Parent" entity-name="ParentObject" table="parent" dynamic-insert="false" dynamic-update="true" optimistic-lock="version"> <id name="rowId" type="long"> <column name="RowID" /> <generator class="native" /> </id> <version name="versionSequence" type="integer" unsaved-value="null" generated="never" insert="false"> <column name="VersionSequence" /> </version> <many-to-one name="child" entity-name="Child" fetch="select" optimistic-lock="true" embed-xml="false" update="true" insert="false"> <column name="ChildID" /> </many-to-one> <property name="dateCreated" type="timestamp"> <column name="DateCreated" length="0" /> </property> <property name="dateUpdated" type="timestamp" update="false"> <column name="DateUpdated" length="0" /> </property> </class> </hibernate-mapping> <hibernate-mapping> <class name="com.Child" entity-name="Child" table="Child" dynamic-insert="false" dynamic-update="true" optimistic-lock="version"> <id name="childId" type="long" > <column name="ChildID" /> <generator class="native" /> </id> <version name="versionSequence" type="integer" insert="false" generated="never" > <column name="VersionSequence" /> </version> <property name="childKey" type="string" > <column name="ChildKey" length="20" /> </property> <property name="childName" type="string" > <column name="ChildName" length="30" /> </property> <property name="childNumber" type="string" > <column name="ChildNumber" /> </property> <property name="dateCreated" type="timestamp"> <column name="DateCreated" /> </property> <property name="dateUpdated" type="timestamp" update="false"> <column name="DateUpdated" /> </property> </class> </hibernate-mapping>
