  • Tracing spoofed mobile phone numbers

    - by RaDeuX
    I am being harassed by some prank caller that is spoofing his/her number neither T-Mobile nor the police can do anything about it. I have been told from one of my friends that if I set up an Asterisk server, I can accomplish the tracing of the prank caller. I am hardly knowledgeable in terms of networking, so a lot of what they told me was filled with jargon I couldn't really understand. But first things first, I downloaded Asterisk 1.5.0 and was finally able to install it (had issues with partitioning... In the end I just had Asterisk hog the entire HDD space). I tried out Asterisk, and it was slightly complicated for me so I decided to install trixbox 2.8.0.4 instead. It looks very similar to Asterisk... I'm not entirely sure what to do from here. I know I have to get the server up and running, but do I need a PBX card or something to accomplish what I'm trying to do? I'm running trixbox on a laptop to minimize electricity usage. Also, will I have to open any ports for the server? I have limited administrative permissions because of my father who is very uncomfortable with opening ports.

  • Assignment to LAN queues (qWAN1 & qWAN2) from dual-WAN in pfSense

    - by Kurian
    I need help creating floating rules in pfSense for the following: I have two upper limited download queues qWAN1 and qWAN2 on my LAN interface. Each has its own qACK1, qDefault1 etc. How do I assign all unclassified traffic from WAN1 to LAN->qWAN1->qDefault1 and from WAN2 to LAN->qWAN2->qDefault2. qLink is the one and only default queue on LAN so that I get wire speed to the pfSense host from the LAN.

  • ActiveMQ - Removing queues programatically

    - by Eduardo Z.
    Fellow StackOverflowers, is there a way for me to remove a queue or a topic in ActiveMQ programatically? I am using ActiveMQ's standard persistency, and my application requires that, on startup, all new queues be dynamically re-created (unless there are messages stored in the queue, in which case, the queue should remain to exist). I am also creating all queues programatically through sessions. Is there an equivalent to that procedure, only to delete a queue? Querying and iterating through the existing queues would also be useful, but i haven't found a way to do that yet. Please help an ActiveMQ noob! =)

  • WAS hosting of queues

    - by user80855
    I read that when hosting a queue endpoint all these names need to match: Hosted in IIS at: http://localhost/MyService.svc service endpoint address: http://localhost/private/MyService.svc queue: .\private$\MyService.svc So I wonder, how can you host a service with multiple endpoints to different queues? For example a service that is listening to two queues… (using two endpoints).

  • Allowing asterisk in URL - ASP.NET MVC 2 - .NET 4.0 or encoding

    - by raRaRa
    I'm having a trouble allowing asterisk (*) in the URL of my website. I am running ASP.NET MVC 2 and .NET 4.0. Here's an example that describes the problem: http://mysite.com/profile/view/Nice* The username is Nice* and ASP.NET says there are illegal characters in the URL: Illegal characters in path. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentException: Illegal characters in path. I have tried all the Web.config methods I've seen online such as: <pages validateRequest="false"> and <httpRuntime requestPathInvalidCharacters="" requestValidationMode="2.0" /> So my question is: Is it possible to allow asterisk in URL? If not, is there some encoding method in .NET that can encode asterisk(*) ? Thanks!

  • When should you NOT use the asterisk (*) when declaring a variable in Objective C

    - by Jason
    I have just started learning objective c and the asterisk is giving me some trouble. As I look through sample code, sometime it is used when declaring a variable and sometimes it is not. What are the "rules" for when it should be used. I thought it had something to do with the data type of the variable. (asterisk needed for object data types, not needed for simple data types like int) However, I have seen object data types such as CGPoint declared without the asterisk as well? Is there a definitive answer or does it have to do with how and what you use the variable for?

  • JBossMQ - Clustered Queues/NameNotFoundException: QueueConnectionFactory error

    - by mfarver
    I am trying to get an application working on a JBoss Cluster. It uses Queues internally, and the developer claims that it should work correctly in a clustered environment. I have jbossmq setup as a ha-singleton on the cluster. The application works correctly on whichever node currently is running the queue, but fails on the other nodes with a: "javax.naming.NameNotFoundException: QueueConnectionFactory not bound" error. I can look at JNDIview from the jmx-console and see that indeed the QueueConnectionFactory class only appears on the primary node in the Global context. Is there a way to see the Cluster's JNDI listing instead of each server? The steps I took from a default Jboss 4.2.3.GA installation were to use the "all" configuration. Then removed /server/all/deploy/hsqldb-ds.xml and /deploy-hasingleton/jms/hsqldb-jdbc2-service.xml, copying the example/jms/mysq-jdbc2-service.xml file into its place (editing that file to use DefaultDS instead of MySqlDS). Finally I created a mysql-ds.xml file in the deploy directory pointing "DefaultDS" at an empty database. I created a -services.xml file in the deploy directory with the queue definition. like the one below: <server> <mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.mq.destination:service=Queue,name=myfirstqueue"> <depends optional-attribute-name="DestinationManager"> jboss.mq:service=DestinationManager </depends> </mbean> </server> All of the other cluster features of working, the servers list each other in the view, and sessions are replicating back and forth. The JBoss documentation is somewhat light in this area, is there another setting I might have missed? Or is this likely to be a code issue (is there different code to do a JNDI lookup in a clusted environment?) Thanks

  • Does RabbitMq do round-robin from the exchange to the queues

    - by Lancelot
    Hi, I am currently evaluating message queue systems and RabbitMq seems like a good candidate, so I'm digging a little more into it. To give a little context I'm looking to have something like one exchange load balancing the message publishing to multiple queues. I don't want to replicate the messages, so a fanout exchange is not an option. Also the reason I'm thinking of having multiple queues vs one queue handling the round-robin w/ the consumers, is that I don't want our single point of failure to be at the queue level. Sounds like I could add some logic on the publisher side to simulate that behavior by editing the routing key and having the appropriate bindings in place. But that's kind of a passive approach that wouldn't take the pace of the message consumption on each queue into account, potentially leading to fill up one queue if the consumer applications for that queue are dead. I was looking for a more pro-active way from the exchange entity side, that would decide where to send the next message based on each queue size or something of that nature. I read about Alice and the available RESTful APIs but that seems kind of a heavy duty solution to implement fast routing decisions. Anyone knows if round-robin between the exchange the queues is feasible w/ RabbitMQ then? Thanks.

  • Best Practical RT, sorting email into queues automatically using procmail

    - by user52095
    I'm trying to get incoming e-mail to automatically go directly into whichever queue/ticket they are related to or create a new one if none exist and the right queue e-mail setup in the web interface is used. I will have too many queues to have two line items within mailgate per queue. A similar issue was discussed here (http://serverfault.com/questions/104779/procmail-pipe-to-program-otherwise-return-error-to-sender), but I thought it best to open a new case instead of tagging on what appeared to be an answer to that person's query. I'm able to send and receive e-mail (via PostFix) to the default rt user and this user successfully accepts all e-mail for the relative domain. I have no idea where the e-mail goes - it's successfully delivered, but it does not update existing tickets (with a Subject line match) and it does not create any new. Here's and example of my ./procmail.log: procmail: [23048] Mon Aug 23 14:26:01 2010 procmail: Assigning "MAILDOMAIN=rt.mydomain.com " procmail: Assigning "RT_MAILGATE=/opt/rt3/bin/rt-mailgate " procmail: Assigning "RT_URL=http://rt.mydomain.com/ " procmail: Assigning "LOGABSTRACT=all " procmail: Skipped " " procmail: Skipped " " procmail: Assigning "LASTFOLDER={ " procmail: Opening "{ " procmail: Acquiring kernel-lock procmail: Notified comsat: "rt@18337:./{ " From [email protected] Mon Aug 23 14:26:01 2010 Subject: RE: [RT.mydomain.com #1] Test Ticket Folder: { 1616 Does the notified comsat portion mean that it notified RT?

  • Server Fax Farm - Need suggestions, or advice

    - by Mike Curry
    We're Looking at creating a large fax farm via T.38 (Fax over Voip - hundreds of incoming and outgoing faxes) on linux servers, anyone have any suggestions on what is available? All my searches return using Asterisk 1.6.x with a commercial product from Digium called "Fax for Asterisk" (with required purchase of "channels" at $38.00 per channel). There must be an open source project out there I can't seem to find. Suggestions welcome! Here is some additional info: We're using Ubuntu 9.10, and planning to use T.38 If I have missed anything, let me know.

  • Why *do* windows print queues occasionally choke on a print job

    - by Ian
    Y'know they way windows print queues will occasionally stop working with a print job at the head of the queue which just won't print and which you can't delete? Anyone know whats going on when this happens? I've been seeing this since the NT4 days and it still happens on 2008. I'm talking about standard IP connected laser printers - nothing fancy. I support a lot of servers and loads of workstations and see this happen a few times a year. The user will call saying they can't print. When you examine the print queue, which in my case will generally be a server based queue shared out to the workstations, you find a print job which you cannot cancel. You also can't pause it, reinitialize it, nothing. Stopping the spooler is the usual trick and works sometimes. However I occasionally see cases which even this doesn't cure and which a reboot is the only solution. Pause the queue, reboot, when it comes back up the job can then be deleted. Once gone the printer happily goes back to its normal state. No action is ever necessary on the printer. I regard having to reboot as last resort and don't like it. What on earth can be going on when stopping the process (spooler) and restarting it doesn't clear a problem? Its not linked to any manufacturer either. I've seen this on HPs, lexmark, canon, ricoh, on lasers, on plotters.... can't say I ever saw this on dot matrix. Anyone got any ideas as to what may be going on. Ian

  • activemq round robin between queues or topics

    - by forkit
    I'm trying to achieve load balancing between different types of messages. I would not know in advance what the messages coming in might be until they hit the queue. I know I can try resequencing the messages, but I was thinking that maybe if there was a way to have the various consumers round robin between either queues or between topics, this would solve my problem. The main problem i'm trying to solve is that I have many services sending messages to one queue with many consumers feeding off one queue. I do not want one type of service monopolizing the entire worker cluster. Again I don't know in advance what the messages that are going to hit the queue are going to be. To try to clearly repeat my question: Is there a way to tell the consumers to round robin between either existing queues or topics? Thank you in advance.

  • Unit testing task queues in AppEngine

    - by Swizec Teller
    For a very long time now I've been using task queues on AppEngine to schedule tasks, just the way I'm supposed to. But what I've always been wondering is how does one write tests for that? Until now I've simply made tests to make sure an error doesn't occur on the API that queues a task and then wrote the more proper tests for the API executing the task. However lately I've started feeling a bit unsatisfied by this and I'm searching for a way to actually test that the correct task has been added to the correct queue. Hopefully this can be done better than simply by deploying the code and hoping for the best. I'm using django-nonrel, if that has any bearing on the answer. To recap: How can a unit test be written to confirm tasks have been queued?

  • How to send T.38 from a mac?

    - by Brian Postow
    I'm trying to set up a fax-server on a macintosh. I have Hylafax, and we're going to use an internet FOIP fax provider (Haven't decided who yet, that may be another question). The problem is how to get from Hylafax to T.38. I know of two options, but I'm not sure how to decide between them: T38modem Advantages: It's only one extra program, and i know that I can compile it for the Mac. (well, At least I can get the H323 version working on a Mac) Disadvantages: It is mostly undocumented and seems to be supported only by one guy in Russia. IAXModem/Asterisk Advantages: It's well known, and well supported. We can pay for support. It presumably does the T38 with SIP correctly, so we don't have to worry about it. Disadvantages: It's two separate programs. While I know how to get Asterisk on a mac, I'm not sure about IAXModem. (It's sourceforge, and linux, but compiling things for a mac isn't always straight forward...) It's also mostly undocumented. Do these seem like an accurate listing of the pros/cons? Anyone have any other suggestions? thanks.

  • What does the Asterisk * mean in Objective-C?

    - by Thanks
    Is it true, that the Asterisk always means "Hey, that is a pointer!" And an Pointer always holds an memory adress? (Yes I know for the exception that a * is used for math operation) For Example: NSString* myString; or SomeClass* thatClass; or (*somePointerToAStruct).myStructComponent = 5; I feel that there is more I need to know about the Asterirsk (*) than that I use it when defining an Variable that is a pointer to a class. Because sometimes I already say in the declaration of an parameter that the Parameter variable is a pointer, and still I have to use the Asterisk in front of the Variable in order to access the value. That recently happened after I wanted to pass a pointer of an struct to a method in a way like [myObj myMethod:&myStruct], I could not access a component value from that structure even though my method declaration already said that there is a parameter (DemoStruct*)myVar which indeed should be already known as a pointer to that demostruct, still I had always to say: "Man, compiler. Listen! It IIISSS a pointer:" and write: (*myVar).myStructComponentX = 5; I really really really do not understand why I have to say that twice. And only in this case. When I use the Asterisk in context of an NSString* myString then I can just access myString however I like, without telling the compiler each time that it's a pointer. i.e. like using *myString = @"yep". It just makes no sense to me.

  • Recommended FXO Gateway for UK analogue lines

    Can anybody recommend any FXO gateway devices to connect analogue telephone lines to an Asterisk VoIP system. Requirements: Minimum of 4 ports. Enterprise grade - quality is more important than price. For UK analogue telephone lines. - I don't know if this makes a difference or not? I'd also be interested to hear bad experiences, so I can get an idea of which devices to avoid.
