Application to run on ports

shafi2all · #1 (**permalink**) 07-29-2008

I do not have much idea about ports.

How can i make an application(written in C) to run on a specific port ?

Does the code internally written in C says about port number where the application to run ? Can i make an application to select port dynamically which are closed(other than standard ports for telnet, ftp ...) ?

Does some how port numbers are related to hardware ?

Thanks in advance !

check /etc/services file which will give detailed information about ports used by which application.

Oh, Beej's guide gives you answers to most (if not all) of your questions.
