That is the app use Port 631 IPP

Hello

I have a doubt, I know port 631 it's cups or ipp service, but I don't have any printer installed or configured, I recently format my Mac with the restore option as a Trojan horse, but know with only installed pages and numbers that I did with the network utility portscanning and without opening any program , I opened port 631 PPI, and do a netstat it seems local address localhost.ipp and *. * address abroad.

My question is, which service or program might use this port if I didn't set up a printer or the printer shared on the local area network?

Generally sound is not open, but I am concern when it is

Thank you

try from the command line, copy and paste:

lsof - i: 631

In the list use the procces xxxxx

To release the port, kill the process using it:

kill xxxxx

    It seems that 'Sleep' provides exactly the functionality you're looking for!  It is immediate, and, if you wish, it can lock your screen immediately.  It allows to "leave the House with my mac on."

    What exactly are you trying to do?  (Not to say how you try to do so, simply enter what you are trying to accomplish).

  • That is the app automatically downloads every three hours suck huge amounts of data?  How do I turn it off?

    On the iPhone 6 sec, that either the app downloads every 3 hours, using huge amounts of data?

    As nobody here knows what applications do you have on your phone, there is no way we could answer that.

    To start to figure it out, go to settings > cellular and made scroll down to see which applications are using a large amount of data. Disable cellular data for those who use a lot without reason you can think and see if this will have an impact.

    Also, many carriers use only newspaper given every so many hours. Maybe it's a running total for these three hours.

  • Alerts within the app using


    Great question and the answer is: Yes you can.

    To do this, you must set a element to the blackberry.app JavaScript API in the config.xml file.  Once this operation is complete, you can then make a call to the blackberry.app.version property to retrieve the value of the 'version' field that is defined in your config.xml file.  Note You can even use blackberry.app.name to dynamically fill the value "MyAppName" in your about box.

    function showAbout()
    {
        var s = "v" + blackberry.app.version + "\n";
        s += "©" + blackberry.app.copyright + "\n";
        s += "By: " + blackberry.app.author + "\n";
        s += blackberry.app.name;
        alert(s);
    }

  • I want to create my logo. Can anyone recommend that either the app might work better and how to start?

    I'm late in the Department and the logo. I have been using temporary but I'm ready for a logo custom design and I need to know, a person more experienced that I am, what program would work better and how to start. If anyone, out there, can get me going in the right direction, I'll send them a gift certificate good for a nice discount on the purchase of my jewelry line. Just provide a contact method.


    Thank you all in advance for any help you can give.

    I wouldn't say that anything in the creative clouds is suitable for a beginner. They are all professional tools with a steep learning curve. Education and training is highly recommended and can be essential if you do not have a background in graphic design. I looked at experienced artists, pull your hair to try to use Illustrator to do the simple things.

    However, the choice of professionals for a logo is certainly Illustrator.

    Start with a pencil and paper, however, until you have your idea. Then use your skill in Illustrator to make a polished design.

  • build the app using dps in indesign

    I want to rebuild my app in indesign and he keeps asking me to re-download all splash screens, etc... is it necessary whenever we make a change to our mobile application?  There is no way to keep the same settings and rebuild the content?

    Only if the application was built on the same machine and the location of your icons has not changed since the last build of your application, Viewer Builder should remember the path to the icons and ask not to re - new link icons.
