Er ... does you /etc/services include a line like

ssh             22/tcp                          # Secure shell

When you use functions like getservby[name|port] they will scan *your*
/etc/services file and look for the corrispondent name/port.

[man getservbyname e.g]

DESCRIPTION
     The getservent(), getservbyname(), and getservbyport() functions each re-
     turn a pointer to an object with the following structure containing the
     broken-out fields of a line in the network services data base,
     /etc/services.
