Oh, echo and www are just examples. There are many services ( like
listserv, imap, pop{2,3}, bootp{s,c} ) that use both protocols. Does

Excuse me if i sound naive but i think an application can not talk
connection oriented and connection less protocols from the same port at
the same time?? Isnt it true?
