  • Can Bonjour browse a service with a particular name?

    - by Roman
    Bonjour provides "DNSSD.browse(serviceType,callBackObject)" method which browses for services of a particular type. If a service of the given type is found, Bonjour call "callBackObject.serviceFound". If the service is lost, Bonjour calls "callBackObject.serviceLost". I alway considered "DNSSD.browse" as a method for monitoring a particular service. Bonjour monitors a particular service and calls necessary method if the service is found (available) or lost (not available). But than I realized that "DNSSD.browse" receives (as argument) a type of service (for example "http.tcp") and there can be several services of this type. So, its probably calls "serviceFound" and "serviceLost" if any service of the specified type is found or lost, respectively. But in my application I would like to browse just for one particular service. What is the best way to do it? I have two potential solutions: When I register a service, I give it a unique type. For example: "server1.http.tcp". I register services with unique names (not types) and ask Bonjour to browse for services with particular names. But I am not sure that Bonjour provide such possibility. Can it browse for services with specific names?

  • Route return traffic to correct gateway depending on service

    - by Marnix van Valen
    On my office network I have two internet connections and one CentOS server running a website (HTTPS on port 443). The website should be publicly accessible through the public IP of the first internet connection (ISP-1). The other internet connection, ISP-2, id the default gateway on the network. Both internet connections have routers (the household-kind) with NAT, SPI firewalls etc. The router on ISP-2 is a Netgear WNDR3700 (aka N600) with original firmware. The problem is that the website is unreachable. Looks like incoming traffic on ISP-1 will reach the server but the returning traffic is routed through ISP-2, effectively making the site unreachable. As far as I can tell I can't do port based routing on the WNDR3700. What are my options to make this work? I've been looking at implementing an iptables / routing based solution on the server itself but haven't been able to make that work. Update: Note that the server has one network interface connecting it to both routers.

  • ASP MVC Populate drop down list on jQuery add table row

    - by Jacob Huggart
    I have a page with several drop down lists that all have the same contents. The page starts out with only three ddls, but more need to be added based on user input. There is also other information associated with the drop down lists that is all in a table. So, when the user clicks a link I add a new row of textboxes and drop down lists to a table. When I add a row to my table, the new drop down lists are empty because there is no view data associated with them. How can I use ajax or jquery to pull the viewdata that I need to populate new drop down lists?

  • Add every value in stack

    - by rezivor
    I am trying to figure out a method that will add every value in a stack. The goal is to use that value to determine if all the values in the stack are even. I have written to code to do this template <class Object> bool Stack<Object>::objectIsEven( Object value ) const { bool answer = false; if (value % 2 == 0) answer = true; return( answer ); } However, I am stumped on how to add all of the stack's values in a separate method

  • Duplicate C# web service proxy classes generated for Java types

    - by Sergey
    My question is about integration between a Java web service and a C# .NET client. Service: CXF 2.2.3 with Aegis databinding Client: C#, .NET 3.5 SP1 For some reason Visual Studio generates two C# proxy enums for each Java enum. The generated C# classes do not compile. For example, this Java enum: public enum SqlDialect { GENERIC, SYBASE, SQL_SERVER, ORACLE; } Produces this WSDL: <xsd:simpleType name="SqlDialect"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="GENERIC" /> <xsd:enumeration value="SYBASE" /> <xsd:enumeration value="SQL_SERVER" /> <xsd:enumeration value="ORACLE" /> </xsd:restriction> </xsd:simpleType> For this WSDL Visual Studio generates two partial C# classes (generated comments removed): [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="SqlDialect", Namespace="http://somenamespace")] public enum SqlDialect : int { [System.Runtime.Serialization.EnumMemberAttribute()] GENERIC = 0, [System.Runtime.Serialization.EnumMemberAttribute()] SYBASE = 1, [System.Runtime.Serialization.EnumMemberAttribute()] SQL_SERVER = 2, [System.Runtime.Serialization.EnumMemberAttribute()] ORACLE = 3, } [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.3082")] [System.SerializableAttribute()] [System.Xml.Serialization.XmlTypeAttribute(Namespace="http://somenamespace")] public enum SqlDialect { GENERIC, SYBASE, SQL_SERVER, ORACLE, } The resulting C# code does not compile: The namespace 'somenamespace' already contains a definition for 'SqlDialect' I will appreciate any ideas...

  • EC2 configuration for medium load service on Django

    - by Luberg
    I have created a very basic Django application which puts an email to the database (Coming soon page for a startup). I launched a t1.micro instance to try out which load it can carry out. Nginx+FastCGI from Django+sqllite/postgres - tried both. blitz.io test gave me a pretty unhappy result (just 100 users within 1 minute): This rush generated 542 successful hits in 1.0 min and we transferred 809.01 KB of data in and out of your app. The average hit rate of 8.81/second translates to about 761,612 hits/day. You got bigger problems though: 87.28% of the users during this rush experienced timeouts or errors! I tried both to put varnish, disabled Debub mode in django and started fastcgi in threaded mode - nothing helps. This is not gonna be a super highload page - just a coming soon page to save email of subscribers, it should carry at least 500-1000 users at the same time in peak... I believe t1.micro is super small for that, but I also have tried small instance - not better result.. Please let me know should I use something different from Amazon EC2, or to pick smth better than t1.micro, or I that is definetely a configuration issues?...

  • how to add value to windows installer property table

    - by Felix
    According to MSDN installer sets ROOTDRIVE to the local drive that can be written to having the most free space. In my situation it is a slow USB drive that I use for nightly backup, but I would prefer to use my C drive for the install folder. But somehow I can't figure out how to set this property from command line or through PowerShell. I found that it is possible, but these instructions don't make any sense

  • VBA Add to Array and Use Previous Value

    - by MattHead93
    I'm trying to write some code that will take a value WeekNum, and add it to an array Week(1 To 51), and then associate a value from a Textbox TargDef. Once this has been added to the array, I want to look up the value of the array for the previous WeekNum and add it to a value ProdTarg. I've created this much so far: Dim Week(1 To 51) Dim Count As Integer If TargDef < 0 Then Count = WeekNum Week(Count) = Abs(Val(TargDef)) If Val(Week((Count) - 1)) = 0 Then ProdTarg = Val(ProdTarg) Else ProdTard = Val(ProdTarg) + Val(Week((Count) - 1)) End If End If I am currently receiving the error "Subscript out of Range" for the line If Val(Week((Count) - 1)) = 0 Then Any help will be greatly appreciated!

  • How can I update Firefox add-ons automatically?

    - by Maelstrom
    Similar to this question, is it possible to update installed plugins via the command line? I'm running YSlow with beacon reporting as a nightly cron job under OSX: /Applications/Firefox.app/Contents/MacOS/firefox-bin -no-remote -P YSlow http://www.example.com/ & PID=$! sleep 300 kill $PID This dumps FF into the background and grabs the PID, waits 300 seconds (for the page to load) then kills it. If there is an update pending, the browser "hangs" waiting for a confirmation. If I do click on the "install updates" link, everything works and then Firefox launches a new process - the $! returned by the shell is no longer valid. Can I update a plugin from the command line without confirmation? Can I curl the XPI into a file and install it without confirmation?

  • Add Bookmark to IE automatically for new users on a computer

    - by Kyle Brandt
    When I set up a PC, I would like to be able to have it so when anyone logs into that PC from the domain a couple of IT bookmarks will be in IE. I read I can do this with a Domain-Level group policy, but unfortunately, with my current domain group policies have not gone well, so I have fear (Rather not get into this in this question). Can I do this at the PC level when I deploy a new computer? So any domain users who log into the PC will have these bookmarks added when their profile is created (no roaming profiles). These are XP machines, and the domain is run by 2003 controllers.

  • How do I add permissions via command line for "everyone" on external HDD

    - by acidzombie24
    I have an external HDD and I kind of messed up the file permissions but when fixing it I thought it is ok bc with my username I can access the files perfectly fine. Now that I use this with two PC (actually ATM I don't have access to my other PC) I can't access these files. The problem is this directory has hundreds of folders with no permission for "everyone". I would like to give it the default permissions including have all access for the user "everyone". How do I do that via command line for these hundreds of folders?

  • Managing service passwords with Puppet

    - by Jeff Ferland
    I'm setting up my Bacula configuration in Puppet. One thing I want to do is ensure that each password field is different. My current thought is to hash the hostname with a secret value that would ensure each file daemon has a unique password and that password can be written to both the director configuration and the file server. I definitely don't want to use one universal password as that would permit anybody who might compromise one machine to get access to any machine through Bacula. Is there another way to do this other than using a hash function to generate the passwords? Clarification: This is NOT about user accounts for services. This is about the authentication tokens (to use another term) in the client / server files. Example snippet: Director { # define myself Name = <%= hostname $>-dir QueryFile = "/etc/bacula/scripts/query.sql" WorkingDirectory = "/var/lib/bacula" PidDirectory = "/var/run/bacula" Maximum Concurrent Jobs = 3 Password = "<%= somePasswordFunction =>" # Console password Messages = Daemon }
