For the sake of simplicity, let me explain that as follows:
nmap(1) says about port 111 being available for the rpcbind
/protocol/. This protocol is implemented by /both/ portmap
/and/ rpcbind.
Another example of this sort you've already seen is:
$ nmap -6 ::1 | grep -F 80/tcp
80/tcp open http
$
However, the machine the command above was run on has /no/
“http” installed:
$ dpkg -l http
No packages found matching http.
$
(It has apache2-mpm-prefork installed, though.)
