Re: [Jython-users] Does the jython interpreter open up any ports?

[Melendez,Ulises <Uli...@se...>]

Thanks for the reply, Philip.

To follow up, does Jython have any configuration options that WOULD cause it
to open up any ports?  As a hypothetical, there might be some debug switch
that would allow a remote debugger to connect directly to the Jython
interpreter.  Is there anything along those lines that we could, for safety,
explicitly disable?

Thanks again,


Ulises Melendez

Jython doesn't open any sockets unless you ask it to.

The lsof command on UNIX can show every open file (including sockets)  
for a particular process if you don't believe us. =]
