Welcome to Linux.
Mostly what has been discussed here is networking concepts. The same applies to any
network connected device just the location and way the configuration information is stored
and handled is different .
Just another question, if I can, please:
it exists some fix relation between the "port number" of the servers and the
theirs IP number ?
It is some kind of correlation between them ?
The analogy of the telephone number and extension is a good one. The only thing I would
add is that the extension (port/service) number is generally fixed, standardized.
A list is kept by the IANA (Internet Assigned Numbers Authority) and can be seen here....
