How to create WSDL file with Eclipse
WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. WSDL stands for Web Services Description Language. The WSDL is an abstract definitions of ports and messages, being separated from the concrete implementation. Using this model to define the service allows the reuse of these definitions and also will allow to implement server and client independently.
Change ssh default port in Linux
By default, ssh listens for incoming connections on port 22. So if a hacker wants to attack your machine he will most likely scan port 22 first. Just to make an idea how important is this (from my point of view of course), before changing the default ssh port for my server I got every day 1000+ login tries for my root user. An effective (but minimal) method to protect your machine is to run ssh on non-standard port. Any unused port will work but one above 1024 is preferable.
