I have setup one application 'phanthomjs' that is running of specific port 6423 I wish that it should be accessible to script that are run locally on the box 'localhost', not accessible from outside.
phantomjs--webdriver=6324
my current script make use of TCP and run on same box and we make use server name as localhost
for making connection to the application.
Is there any way to in Redhat Linux box to block the access to this port from outside?
