• Difficulty creating a paging function with MySQL and ColdFusion

  - by Mel

  I'm trying to create pagination for search results using MySQL and ColdFusion. My intention is to only retrieve the queries that can be displayed on a single page, thus making the process efficient. I tried using two queries in my function, but I could not return two variables to the cfinvoke. The following code does not paginate, but it displays the result search results using a CFC: <!---DEFINE DEFAULT STATE---> <cfparam name="variables.searchResponse" default=""> <cfparam name="URL.titleName" default=""> <cfparam name="URL.genreID" default=""> <cfparam name="URL.platformID" default=""> <!---TitleName can only be blank if one or both genre and platform are selected---> <cfif StructKeyExists(URL, "searchQuery") AND (Len(Trim(URL.titleName)) LTE 2 AND Len(URL.genreID) IS 0 AND Len(URL.platformID) IS 0)> <cfset variables.searchResponse = "invalidString"> <cfelseif StructKeyExists(URL, "searchQuery")> <cfinvoke component="gz.cfcomp.test" method="searchGames" returnvariable="resultData" argumentcollection="#URL#"> <cfset variables.searchResponse = "hasResult"> </cfif> <cfif searchResponse EQ "hasResult" AND resultData.RecordCount EQ 0> <cfset variables.searchResponse = "noResult"> </cfif> Using this logic, I can display what I need to display on the page: <cfif searchResponse EQ "invalidString"> <cfoutput>Invalid search</cfoutput> </cfif> <cfif searchResponse EQ "noResult"> <cfoutput>No results found</cfoutput> </cfif> <cfif searchResponse EQ "hasResult"> <cfoutput>Display Results</cfoutput> </cfif> If I were executing the queries on the same page, it would be easy to follow the many tutorials out there. But the queries are executing in a function. Displaying the data is easy, but paginating it has become a nightmare for me. Here is my function: <cffunction name="searchGames" access="public" output="false"> <cfargument name="titleName" required="no" type="string"> <cfargument name="genreID" required="no" type="string"> <cfargument name="platformID" required="no" type="string"> <!--- DEFINE LOCAL VARIABLES---> <cfset var resultData = ""> <!---GET DATA---> <cfquery name="resultData" datasource="myDSN"> SELECT * <!---JOINS FOR GENRE/PLATFORM GO HERE---> WHERE <!---CONDITIONS GO HERE---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultData> </cffunction> To paginate, I thought about modifying my function to the following (a new query using a count statement): <!--- DEFINE LOCAL VARIABLES---> <cfset var resultCount = ""> <!---GET DATA---> <cfquery name="resultCount" datasource="myDSN"> SELECT COUNT(gameID) AS rowsFound FROM GAMES <!---JOINS FOR GENRE/PLATFORM GO HERE---> WHERE <!---CONDITIONS GO HERE---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultCount> Then I figured if there is a result to return, I would execute a nested query and create the pagination variables: <cfif resultCount.rowsFound GTE 0> <cfparam name="pageNumber" default="1"> <cfset var recordsPerPage = 5> <cfset var numberOfPages = Int(resultCount.RecordCount / recordsPerPage)> <cfset var recordsToSkip = pageNumber * recordsPerPage - recordsPerPage> <!---DEFINE LOCAL VARIABLE---> <cfset var resultData = ""> <cfquery name="resultData" datasource="myDSN"> <!---GET DATA AND SEND IT BACK USING LIMIT WITH #recordsToSkip# and #RecordsPerPage#---> </cfquery> <!---RETURN VARIABLE---> <cfreturn resultData> </cffunction> I figured I would return two variables: resultCount and resultData. I would use #resultCount# to build my pagination, and #resultData# to display the output. The problem is I can't return two variables in the same cfinvoke tag. Any ideas of how to approach the the right way? I'm totally lost as to the logic I need to follow.

• Combobox binding with different types

  - by George Evjen

  Binding to comboboxes in Silverlight has been an adventure the past couple of days. In our framework at ArchitectNow we use LookupGroups and LookupValues. In our database we would have a LookupGroup of NBA Teams for example. The group would be called NBATeams, we get the LookupGroupID and then get the values from the LookupValues table. So we would end up with a list of all 30+ teams. Our lookup values entity has a display text(string), value(string), IsActive and some other fields. With our applications we load all this information into the system when the user is logging in or right after they login. So in cache we have a list of groups and values that we can get at whenever we want to. We get this information in our framework simply by creating an observable collection of type LookupValue. To get a list of these values into our property all we have to do is. var NBATeams = AppContext.Current.LookupSerivce.GetLookupValues(“NBATeams”); Our combobox then is bound like this. (We use telerik components in most if not all our projects) <telerik:RadComboBox ItemsSource="{Binding NBATeams}”></telerik:RadComboBox> This should give you a list in your combobox. We also set up another property in our ViewModel that is a just single object of NBATeams  - “SelectedNBATeam” Our selectedItem in our combobox would look like, we would set this to a two way binding since we are sending data back. SelectedItem={Binding SelectedNBATeam, mode=TwoWay}” This is all pretty straight forward and we use this pattern throughout all our applications. What do you do though when you have a combobox in a ItemsControl or ListBox? Here we have a list of NBA Teams that are a string that are being brought back from the database. We cant have the selected item be our LookupValue because the data is a string and its being bound in an ItemsControl. In the example above we would just have the combobox in a form. Here though we have it in a ItemsControl, where there is no selected item from the initial ItemsSource. In order to get the selected item to be displayed in the combobox you have to convert the LookupValue to a string. Then instead of using SelectedItem in the combobox use SelectedValue. To convert the LookupValue we do this. Create an observable collection of strings public ObservableCollection<string> NBATeams { get; set;} Then convert your lookups to strings var NBATeams = new ObservableCollection<string>(AppContext.Current.LookupService.GetLookupValues(“NBATeams”).Select(x => x.DisplayText)); This will give us a list of strings and our selected value should be bound to the NBATeams property in our ItemsSource in our ItemsControl. SelectedValue={Binding NBATeam, mode=TwoWay}”

• prism and multiple screens

  - by Avi

  OK - I am studying Prism a little because of a "free weekend" offer on Pluralsight. As this is proving too complex for me, I went to the Prism book and looked at the forward, and this is what it said: What comes after “Hello, World?” WPF and Silverlight developers are blessed with an abundance of excellent books... There’s no lack of tutorials on Model-View-ViewModel ... But they stop short of the guidance you need to deliver a non-trivial application in full. Your first screen goes well. You add a second screen and a third. Because you started your solution with the built-in “Navigation Application Template,” adding new screens feels like hanging shirts on a closet rod. You are on a roll. Until the harsh reality of real application requirements sets in. As it happens, your application has 30 screens not three. There’s no room on that closet rod for 30 screens. Some screens are modal pop-ups; you don’t navigate to a pop-up. Screens become interdependent such that user activity in one screen triggers changes that propagate throughout the UI. Some screens are optional; others are visible only to authorized users. Some screens are permanent, while other screens can be opened and closed at will. You discover that navigating back to a previously displayed screen creates a new instance. That’s not what you expected and, to your horror, the prior instance is gone along with the user’s unsaved changes. Now the issue is, I don't relate to this description. I've never been a UI programmer, but same as everyone else I'm using Windows apps such as MS-Office, and web sites such as Amazon, Facebook and StackExchange. And I look at these and I don't see many "so many screens" issues! Indeed, the only applications having many windows I can think of is Visual Studio. Maybe also Visio, a little. But take Word - You have a ribbon and a main window. Or take Facebook: You have those lists on the left (Favorites, Lists, Groups etc.), the status middle, the adds and then the Contacts sidebar. But it's only one page. Of course, I understand that in enterprise scenarios there are dashboad applications where multiple segments of the screen are updated from multiple non-related services. This I dig. But other scenarios? So - What am I missing? What is the "multiple screens" monster Pirsm is supposed to be the silver bullet solution for? Shoud I invest in studying Prism in addition to learning WPF or ASP.NET MVC?

• How do I know if I am using Scrum methodologies?

  - by Jake

  When I first started at my current job, my purpose was to rewrite a massive excel-VBA workbook-application to C# Winforms because it was thought that the new C# app will fix all existing problems and have all the new features for a perfect world. If it were a direct port, in theory it would be easy as i just need to go through all the formulas, conditional formatting, validations, VBA etc. to understand it. However, that was not the case. Many of the new features are tightly dependant on business logic which I am unfamiliar with. As a solo programmer, the first year was spent solely on deciphering the excel workbook and writing the C# app. In theory, I had the business people to "help" me specify requirements, how GUI looks and work, and testing of the app etc; but in practice it is like a contant tsunami of feature creep. At the beginning of the second year I managed to convince the management that this is not going anywhere. I made them start from scratch with the excel-VBA. I have this "issue log" saved on the network, each time they found something they didn't like about the excel-VBA app, they will write it in there. I check the log daily and consolidate issues (in my mind) mainly into 2 groups: (1) requires massive change. (2) can be fixed in current version. For massive change issues, I make a copy of the latest excel-VBA and give it a new version number, then work on it whenever I can. For current version fixes, I make the changes in a few days to a week, and then immediately release it. I also ensure I update the same change in any in-progress massive change future versions. This has gone on for about 4 months and I feel it works great. I made many releases and solved many real issues, also understood the business logic more and more. However, my boss (non-IT trained) thinks what I am doing are just adhoc changes and that i am not looking at the "bigger picture". I am struggling to convince my boss that this works. So I hope to formalise my approach and maybe borrow a buzzword to confuse him. Incidentally, I read about Agile and SCRUM, about backlog and sprints. But it's all very vague to me still. QUESTION (finally): I want to tell him that this is SCRUM! But I want to hold my breath first and ask whether my current approach is considered SCRUM or SCRUM-like? How can I make it more SCRUM-like? Note that I have only myself, there's no project leader or teams.

• Powerful Lessons in Data from the Presidential Election

  - by Christina McKeon

  Now that we’ve had a few days to recover from the U.S. presidential election, it’s a good time to take a step back from politics and look for the customer experience lessons that we can take away. The most powerful lesson is that when you know more about your base, you will have an advantage over your competition. That advantage will translate into you winning and your competition losing. Michael Scherer of TIME was given access to Obama’s data analysts two days before the election. His account is documented in Inside the Secret World of the Data Crunchers Who Helped Obama Win. What we learned from Scherer’s inside view is how well Obama’s team did in getting the right data, analyzing it, and acting on it. This data team recognized how critical it was to break down data silos within the campaign. As Scherer noted, they created “a single system that merged information from pollsters, fundraisers, field workers, consumer databases, and social-media and mobile contacts with the main Democratic voter files in the swing states.” The Obama analysis was so meticulous that they knew which celebrity and which type of celebrity event would help them maximize campaign contributions. With a single system, their data models became more precise. They determined which messages were more successful with specific demographic groups and that who made the calls mattered. Data analysis also led to many other changes in Obama’s campaign including a new ad buying strategy, using social media and applications to tap into supporters’ friends, and using new social news sites. While we did not have that same inside view into Romney’s campaign, much of the post-mortem coverage indicates that Romney’s team did not have the right analysis. As Peter Hamby of CNN wrote in Analysis: Why Romney Lost, “Romney officials had modeled an electorate that looked something like a mix of 2004 and 2008….” That historical data did not account for the changing demographics in the U.S. Does your organization approach data like the Obama or Romney team? Do you really know your base? How well can you predict what is going to happen in your business? If you haven’t already put together a strategy and plan to know more, this week’s civics lesson is a powerful reason to do it sooner rather than later. Your competitors are probably thinking the same thing that you are!

• Understanding the SQL Server 2008 R2 Installation Center

  - by Enrique Lima

  What is available to us through those links?  Have you taken the time to explore and identify what could be useful to you? One of many gems that has come to my attention is the possibility of provisioning SQL Server to work in an image based environment (hint: Virtualization Template perhaps?!?).   Planning: Includes requirements information, documentation, how to guides, online documentation installation and other tools. Among the other tools you will find the System Configuration checker and The Upgrade Advisor. Both tools very important to ensure your deployment and installation would be successful.     Installation:  This sections focuses on getting installations going, from standalone to cluster when it comes to new instances.  Add new nodes to an existing cluster, and also perform upgrades (in this case to SQL Server 2008 R2).  Also part of this is the option to find updates available.   Maintenance: We find in this section, options that will assist us in tasks like repairing corrupt installations to removing nodes from a cluster. An option that is interesting (and we should discuss benefits later in another post) is to be able to do an Edition Upgrade, this is a feature expansion and addition based on your product installation (Developer to Enterprise, for example)   Tools:  From the System Configuration Checker to identify readiness for deployment in a successful manner, to being able to report on features installed.  And being able to run upgrades of existing packages developed in the 2005 offering to the 2008 R2 release for SSIS.   Resources: Useful and essential links to gather information and guidance.   Advanced: Here is where it gets interesting.  I break this down into 3 main groups: Installation Automation: When you install SQL Server there is a configuration file that gets dropped (ConfigurationFile.ini) that would allow for you to perform automated installations.  There are switches and options that go with this to have that process working. Cluster configuration for Sysprep: Create images that are cluster ready, 2 options, start the prep work, and then the complete once at the final destination. Stand-alone configuration for Sysprep:  Like the clustering counterpart, 2 options, prep and complete.  Giving you the option to create standard templates for your SQL Server deployments. I find it fitting that the 3 topics listed here should (and will) be additional topics I will discuss.   Options: Very clear and specific about what this means. Select the Processor Type or the Installation Media Root Path.

Whether its discussion threads, blog posts, Facebook-style profile-pages, or just a simple Instant Messenger application; in one way or another, your employees are connected. What are the objectives of leveraging social media in your organization? Facilitating knowledge transfer More effectively organizing team events Generating inter-community discussions to solve problems Improving resource management Increasing organizational awareness Creating an environment of accountability Do any of the business objectives above stand out to you as needs? If so, consider leveraging the WebCenter Portal Activity Stream as part of your solution. In WebCenter Portal, the Activity Stream feature provides a streaming view of the activities of your connections, actions taken in portals, and business activities that looks a lot like a combined Facebook and Twitter newsfeed. Activity Stream can note when a user: Posts feedback (comments) Uploads a document Creates a new blog, page, event, or announcement Starts a new discussion Streams messages and attachments entered through WebCenter Publisher (similar to Twitter) Through Activity Stream Preferences, you can select which of these activities to show or hide from your personal Activity Stream. Here’s what you get: Real-time stream of activities with in a Portal or sub-Portal increases awareness across your organization or within a working group Complete list of user actions reduces the time-to-find for users that need to interact with the latest activities in your portal Users can publish to their groups when tasks are finished for complete group traceability and accountability, as well as improved resource management. Project discussions and shared documents that require the expertise of someone outside of a working group now get increased visibility across your organization. There’s a reason that commercial Social Media tools like Facebook and Twitter have been so successful – they spread information in an aesthetically appealing and easy to read format.  Strategically placing an Activity Feed within your Portal is analogous to sending your employees a daily newsletter, events calendar, recent documents report, and list of announcements – BUT ALL IN ONE!

• Organization &amp; Architecture UNISA Studies &ndash; Chap 13

  - by MarkPearl

  Learning Outcomes Explain the advantages of using a large number of registers Discuss the way in which compilers optimize register usage Discuss the evolution of CISC machines Describe the characteristics of RISC architecture Discuss the RISC vs. CISC controversy Describe the way in which RISC and CISC design principles can be combined Instruction Execution Characteristics To understand the the line of reasoning of RISC advocates, we need a brief overview of instruction execution characteristics. These include… Operations Operands Procedure Calls These three sections can be studied in depth in the textbook at pages 503 - 505 A number of groups have come up with the conclusion that the attempt to make the instruction set architecture closer to HLLs (High Level Languages) is not the most effective design strategy. Rather HLL’s can be best supported by optimizing performance of the most time-consuming features of typical HLL programs. Generally 3 main characteristics came up to improve performance… Use a large number of registers or use a compiler to optimize register usage Careful attention needs to be paid to the design of instruction pipelines A simplified (reduced) instruction set is indicated The use of a large register optimization One of the most important design principles of RISC machines is the use of a large number of registers. The concept of register windows and the use of a large register file versus the use of cache memory are discussed. On the face of it, the use of a large set of registers should decrease the need to access memory. The design task is to organize the registers in such a fashion that this goal is realized. Read page 507 – 510 for a detailed explanation. Compiler-based register optimization   Reduced Instructions Set Architecture There are two advantages to smaller programs… Because the program takes up less memory, there is a savings in that resource (this was more compelling when memory was more expensive) Smaller programs should improve performance, and this will happen in two ways – fewer instructions means fewer instruction bytes to be fetched and in a paging environment smaller programs occupy fewer pages, reducing page faults. Certain characteristics are common to RISC processors… One instruction per cycle Register-to-register operations Simple addressing modes Simple instruction formats RISC vs. CISC After initial enthusiasm for RISC machines, there has been a growing realization that RISC designs may benefit from the inclusion of some CISC features CISC designs may benefit from the inclusion of some RISC features

• What will be the better way for data retrieval on application that needs to handle limited amount of data.?

  - by Milanix

  This is not really a coding question since, I am not adding any code in here. Since, adding my code snippets itself would make this question really long. Instead, I am pretty interested in knowing a better ways for data retrieval on application that needs to handle limited amount of data which isn't updated regularly. Let's take this example: I am writing an application which gets a schedule as an XML from server. I have written a logic in order to parse XML version and update database only if the version is newer than the local version. Although the update is checked automatically/manually on daily basis based on user preference, the actual version update happens only once per few months or so. Since, this is done by some other authority which doesn't provide API but, rather inform publicly on their changes. The actual XML contains a "(n number of groups)(days in a week) (n number of schedule)" . The group is usually 6 and the number of schedule is usually 2. So basically there would usually be only around 100 strings. Now although I have used SQLite at the moment. I want to know how to make update on database. Should I show progress dialog that the application is updating and exit the app when it's done? Since, my updates are infrequent i don't think this will really harm user experience but, is there any better ways to do it? Because I don't want update to be made when user is searching which is done using database. This will cause an database already open exception. Atleast I have faced this problem before. Is it better to rather parse XML every time when user wants to view certain things or to use SQLite? Since, I make lots of use of adapter in my app to create lists, will that degrade the performance? It would really be a great help if anyone can give me better overview about it. Or may be counter argument against each. Many thanks!

• Understanding When Social Interactions Should Be Resolved in Another Channel

  - by Christina McKeon

  Guest Blogger: Aphrodite Brinsmead, Senior Analyst at Ovum Agents need to respond to customers’ social comments and questions quickly and in the right tone. But more importantly, they need to offer resolutions. Customers care most about how long it takes to find information rather than which channel they are using. They choose to use social media because they are comfortable with the channel and it offers a convenient way to communicate. Ideally agents will resolve questions within social media, but they need guidance as to how and when to escalate interactions to a more private channel. First, businesses should assess the way in which customers are using social media to communicate with them and categorize posts into groups: complaints, feedback, technical queries or more general support questions. They should then consider the types of interactions that can easily be handled within social media and those that need to be followed up in another channel. This will be very dependent on the industry. Examples of queries that can be resolved in social media include Shipping pricing and timeframes Outage updates and resolution plans Flight status information Product stock check Technical support videos or forum posts Availability of facilities Both customers and agents need to be educated about the types of questions they can expect to resolve within social media. As the channel matures as a customer service tool, it needs to have value other than just as a forum for complaints. Social customer service agents need the power to start a web chat or phone call Any questions where customers need to divulge personal details in order to get a resolution will need to be addressed in a private channel: a private social message, web chat, email or phone call. Customers should never disclose their date of birth, social security, credit card number, or healthcare records in a public forum. Flight issues, changes to a booking, billing queries or account updates will all need to be completed via a private interaction. Agents responding to questions on social media need the ability to start a web chat or phone call with the customer. The customer doesn’t want to have to repeat their question and the agent should be empowered to connect customer records and access account or billing information. These agents will need to be trained across different channels and should be able to view all customer communications in one application. They also need to follow up questions that began on a public forum in the initial channel to make it clear that the issue was addressed. In order to make this possible, social media needs to be integrated as part of a broader customer service strategy. Irrespective of how many channels are used to complete an interaction, businesses should prioritize customer satisfaction and issue resolution. They need a clear strategy and trained agents that can handle and respond to social interactions. Follow me on Twitter @diteb.

• Raid superblock missing on single parition. Recovery needed!

  - by user171639

  Ok so I have a 2 TB raid 1 setup that has three partitions: sdc1: linux sdc2: swap sdc3: LVM for data However the LVM will no longer mount. So I thought that I would take the first drive, mount it in linux (ive done this b4), and reset the spare drive to copy the data. Normally I can mount a single drive for data recovery using: sudo su apt-get install mdadm lvm2 mdadm --assemble --scan modprobe dm-mod vgscan vgchange -ay c mount -o ro /dev/c/c /mnt Unfortunately, vgscan doesnot recognize the data partition. It appears as though the superblock on the first drive's data partition was erased while syncing with the second. So now I cannot mount that partition and the second drive is stuck in spare mode. Any ideas? Or a way to force mount the data partition just to copy the data? knoppix@Microknoppix:~$ sudo su root@Microknoppix:/home/knoppix# apt-get install mdadm lvm2 Reading package lists...

• How to get DCOMperm.exe from Microsoft

  - by Doltknuckle

  So I've been trying to solve the "The application-specific permission settings do not grant Local Activation permission" problem and everything I've been reading says I need to get "DCOMperm.exe". There are plenty of links to usage and download links that point to non-MS sources. I'd like to get this direct from Microsoft, but I can't find it there. Some people say that it's part of an SDK, but I'm not sure which one. Does anyone have any experience getting this exe?

Again no luck. What is going on?

  - by BeeS

  I get following error when i try to connect via "HeidiSQL" to my database server (local network) SQL Error (2003): Can't connect to MySQL server on 'X.X.X.X.' (10051) SSH Connection via Putty works fine. I checked the my.cnf file on the server (Ubuntu), but settings like bind_address are correct.

• Public free time server

  - by JL.

  I need to get the current datetime from a reliable source, because its likely that the local system time could be changed. Is it possible to get this from an internet time server, one that has close to 100% uptime, preferably via a webservice method, something that is free, and I have to stress absolutely reliable? I would hope an offering from Microsoft, or the organisation responsible for keeping global time.

• Time Service will not start on Windows Server - System error 1290

  - by paradroid

  I have been trying to sort out some time sync issues involving two domain controllers and seem to have ended up with a bigger problem. It's horrible. They are both virtual machines (one being on Amazon EC2), which I think may complicate things regarding time servers. The primary DC with all the FSMO roles is on the LAN. I reset its time server configuration like this (from memory): net stop w32time w23tm /unregister shutdown /r /t 0 w32tm /register w32tm /config /manualpeerlist:”0.uk.pool.ntp.org,1.uk.pool.ntp.org,2.uk.pool.ntp.org,3.uk.pool.ntp.org” /syncfromflags:manual /reliable:yes /update W32tm /config /update net start w32time reg QUERY HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config /v AnnounceFlags I checked to see if it was set to 0x05, which it was. The output for... w32tm /query /status Leap Indicator: 0(no warning) Stratum: 1 (primary reference - syncd by radio clock) Precision: -6 (15.625ms per tick) Root Delay: 0.0000000s Root Dispersion: 10.0000000s ReferenceId: 0x4C4F434C (source name: "LOCL") Last Successful Sync Time: 10/04/2012 15:03:27 Source: Local CMOS Clock Poll Interval: 6 (64s) While this was not what was intended, I thought I would sort it out after I made sure that the remote DC was syncing with it first. On the Amazon EC2 remote replica DC (Windows Server 2008 R2 Core)... net stop w32time w32tm /unregister shutdown /r /t 0 w32time /register net start w32time This is where it all goes wrong System error 1290 has occurred. The service start failed since one or more services in the same process have an incompatible service SID type setting. A service with restricted service SID type can only coexist in the same process with other services with a restricted SID type. If the service SID type for this service was just configured, the hosting process must be restarted in order to start this service. I cannot get the w32time service to start. I've tried resetting the time settings and tried to reverse what I have done. The Ec2Config service cannot start either, as it depends on the w32time service. All the solutions I have seen involve going into the telephony service registry settings, but as it is Server Core, it does not have that role, and I cannot see the relationship between that and the time service. w32time runs in the LocalService group and this telephony service which does not exist on Core runs in the NetworkService group. Could this have something to do with the process (svchost.exe) not being able to be run as a domain account, as it now a domain controller, but originally it ran as a local user group, or something like that? There seem to be a lot of cases of people having this problem, but the only solution has to do with the (non-existant on Core) telephony service. Who even uses that?

• L2TP iptables port forward

  - by The_cobra666

  Hi all, I'm setting up port forwarding for an L2TP VPN connection to the local Windows 2003 VPN server. The router is a simpel Debian machine with iptables. The VPN server works perfect. But I cannot log in from the WAN. I'm missing something. The VPN server is using a pre-shared key (L2TP) and give's out an IP in the range: 192.168.3.0. Local network range is 192.168.2.0/24 I added the route: with route add -net 192.168.3.0 netmask 255.255.255.240 gw 192.168.2.13 (the vpn server) iptables -t nat -A PREROUTING -p udp --dport 1701 -i eth0 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p udp --dport 1701 -j ACCEPT iptables -t nat -A PREROUTING -p udp --dport 500 -i eth0 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p udp --dport 500 -j ACCEPT iptables -t nat -A PREROUTING -p udp --dport 4500 -i eth0 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p udp --dport 4500 -j ACCEPT iptables -t nat -A PREROUTING -p 50 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p 50 -j ACCEPT iptables -t nat -A PREROUTING -p 51 -j DNAT --to 192.168.2.13 iptables -A FORWARD -p 51 -j ACCEPT The whole iptables script is (without the line's from above): echo 1 > /proc/sys/net/ipv4/ip_forward echo 1 > /proc/sys/net/ipv4/tcp_syncookies #Flush table's iptables -F INPUT iptables -F OUTPUT iptables -F FORWARD iptables -t nat -F #Drop traffic iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT ACCEPT #verkeer naar buiten toe laten en nat aanzetten iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE #RDP forward voor windows servers iptables -t nat -A PREROUTING -p tcp --dport 3389 -i eth0 -j DNAT --to 192.168.2.10:3389 iptables -A FORWARD -p tcp --dport 3389 -j ACCEPT iptables -t nat -A PREROUTING -p tcp --dport 3340 -i eth0 -j DNAT --to 192.168.2.12:3340 iptables -A FORWARD -p tcp --dport 3340 -j ACCEPT #toestaan SSH verkeer iptables -t nat -A PREROUTING -p tcp --dport 22 -i eth0 -j DNAT --to-destination 192.168.2.1 iptables -A INPUT -p tcp --dport 22 -j ACCEPT #toestaan verkeer loopback iptables -A INPUT -i lo -j ACCEPT #toestaan lokaal netwerk iptables -A INPUT -i eth1 -j ACCEPT #accepteren established traffic iptables -A INPUT -i eth0 --match state --state RELATED,ESTABLISHED -j ACCEPT #droppen ICMP boodschappen iptables -A INPUT -p icmp -i eth0 -m limit --limit 10/minute -j ACCEPT iptables -A INPUT -p icmp -i eth0 -j REJECT ifconfig eth1 192.168.2.1/24 ifconfig eth0 XXXXXXXXXXXXX/30 ifconfig eth0 up ifconfig eth1 up route add default gw XXXXXXXXXXXXXXXXXXX route add -net 192.168.3.0 netmask 255.255.255.240 gw 192.168.2.13

• nagios NRPE: Unable to read output

  - by user555854

  I currently set up a script to restart my http servers + php5 fpm but can't get it to work. I have googled and have found that mostly permissions are the problems of my error but can't figure it out.

• Remote Desktop event ID 20499. No noticeable issues

  - by Marc05

  I get a warning event with ID 20499 for TerminalServices-RemoteConnectionManager.The error is: Remote Desktop Services has taken too long to load the user configuration from server \server.domain.home for user administrator. Yet, I don't see any issues (I'm guessing because that user is on the machine local). Why am I getting this warning? I'm on Windows Server 2012 R2 connecting from a Windows 8.1.

• Internet Explorer keeps asking for NTLM credentials in Intranet zone

  - by Tomalak

  Long text, sorry for that. I'm trying to be as specific as possible. I'm on Windows 7 and I experience a very frustrating Internet Explorer 8 behavior. I'm in a company LAN with some intranet servers and a proxy for connecting with the outside world. On sites that are clearly recognized as being "Local Intranet" (as indicated in the IE status bar) I keep getting "Windows Security" dialog boxes that ask me to log in. These pages are served off an IIS6 with "Integrated Windows Security" enabled, NTFS permits Everyone:Read on the files themselves. If I enter my Windows credentials, the page loads fine. However, the dialog boxes will be popping up the next time, regardless if I ticked "Remember my credentials" or not. (Credentials are stored in the "Credential Manager" but that does not make any difference as to how often these login boxes appear.) If I click "Cancel", one of two things can happen: Either the page loads with certain resources missing (images, styleheets, etc), or it does not load at all and I get HTTP 401.2 (Unauthorized: Logon Failed Due to Server Configuration). This depends on whether the logon box was triggered by the page itself, or a referenced resource. The behavior appears to be completely erratic, sometimes the pages load smoothly, sometimes one resource triggers a logon message, sometimes it does not. Even simply re-loading the page can result in changed behavior. I'm using WPAD as my proxy detection mechanism. All Intranet hosts do bypass the proxy in the PAC file. I've checked every IE setting I can think of, entered host patterns, individual host names, IP ranges in every thinkable configuration to the "Local Intranet" zone, ticked "Include all sites that bypass the proxy server", you name it. It boils down to "sometimes it just does not work", and slowly I'm losing my mind. ;-) I'm aware that this is related to IE not automatically passing my NTLM credentials to the webserver but asking me instead. Usually this should only happen for NTLM-secured sites that are not recognized as being in the "Intranet" zone. As explained, this is not the case here. Especially since half of a page can load perfectly and without interruption and some page's resources (coming from the same server!) trigger the login message. I've looked at http://support.microsoft.com/kb/303650, which gives the impression of describing the problem, but nothing there seems to work. And frankly, I'm not certain if "manually editing the registry" is the right solution for this kind of problem. I'm not the only person in the world with an IE/intranet/IIS configuration, after all. I'm at a loss, can somebody give me a hint?
