Once you have ported an OS , you got to enable ethernet facilities .

Then you can run a socket based program (check tutorial) , with this program running all you got to do is access your machine from any other PC connected to the ethernet by specifying the IP address.
That's it, by pinging the server it can execute any task as defined by your program,(Note socket just provides the means of connection,the program must also process data).

If i define port id as 80 and provide service of handling web pages or html contents , then i would have developed a HTTP server.

For a FTP server (check sourcecodes) you have to use a port id of 21.
