I have a JAVA application which runs on Linux. I open a socket that binds to all IP. In production this is not acceptable.

$ netstat -ano | grep 104
tcp        0      0 0.0.0.0:104                 0.0.0.0:*                   LISTEN      off (0.00/0/0)

I which to do this:

$ netstat -ano | grep 104
tcp        0      viewer1.com:104                 0.0.0.0:*                   LISTEN      off (0.00/0/0)

Is this something I can change in my Linux box (red hat) or is it application specific. i.e. I have to modify my code?

    Most likely, you’ll need to modify the Java application to specify a bind address.

    The most commonly used API for server socket construction binds to all address by default. However, there is another that can bind to a specific address. There’s a small chance that the application is already using the latter constructor, and it’s just not configured with a value. If that’s the case, you just need to find out how to configure an address.
