    That's a big vague... what are you trying to do? You could not load the
    software, or you could make your system unable to connect to the internet.
    You could perhaps set the software into "Offline Mode" or something.

    Good luck.

    I didn't quite understand. You mean that the only way is that either to unable the systems to access to internet, or not to run the software?
    The software does not have an offline mode. that's the problem.

    Hi
    So you want the software (it might help if we have a name for it) to
    access a local lan? Or no access? If so does it access a particular
    site, or place on the internet? If for example it was firefox and I
    didn't want anyone accessing say www.ubuntu.com from the local machine
    I could add an entry in /etc/hosts
    Code:
    127.0.0.0 www.ubuntu.com 91.189.94.9

    is what you're looking for something like a Windows
    firewall (zonealarm) where an application must be
    given permission before it can access the Internet?

    something like http://tuxguardian.sourceforge.net/,
    which appears to no longer be in development?

    If you're just looking to stop one application from accessing the internet
    you probably want to mess with iptables.

    Adobe Acrobat 7 decided to 'call home' to log which documents you opened and
    I've seen in iptables entry of ...
    iptables -A OUTPUT -m owner --cmd-owner acroread -j DROP
    suggested as a way to block it.


    You'll have to teach yourself iptables but that's definitely one way of
    doing it.
    Me, I just stopped using acrobat reader :-)

    I guess it might also be possible to achieve this with AppArmor, but might be more complex to set up than iptables.

    I'm absolutely looking for something like zonealarm.

    Code:
    iptables -A OUTPUT -m owner --cmd-owner acroread -j DROP
    I'm trying to stop MATLAB to access the internet. So I supposed that i should put MATLAB instead of acroread. Yes?
    I decided to take a look th iptables tutorial, but it was very long and confusing.
    I guess it might also be possible to achieve this with AppArmor
    I looked for AppArmor in software management, but there are dozens of them, and I don't know which one to install.



    This might help. When I start MATLAB, it says this in the terminal:
    libxcb: WARNING! Program tries to unlock a connection without having acquired
    a lock first, which indicates a programming error.
    There will be no further warnings about this issue.

    what does this mean?

    I don't wanna give up and stop using MATLAB.
