Actually, that's not quite what you see here.

Unfortunately I don't read Portuguese so I'll explain this in terms of
the command output in English:

Active Internet connections
Proto Recv-Q Send-Q  Local Address          Foreign Address     State

There are two things to note here -- one is that "State" for all these
connections is "ESTABLISHED" -- these are live connections, not what
you are looking for (which is a state marked "LISTEN").

Second, the column with all the at1:nfs bits is your side (see "Local
Address") , and the at110x bits in the 79x range are the remote side
("Foreign Address"). This indicates your local machine is speaking to
those foreign machines from its local port "nfs". I suspect that means
that at1 is an NFS server and they're mounting file systems from it.
Probably not the information you are looking for.

Try doing this:

netstat | grep LISTEN

That will show just the sockets being listened on (or do the
equivalent by hand in looking at the output.)

BTW, if you could do LANG or LC_ALL=C before sending more output, it
will make it more readable for those of us who don't read
Portuguese. :) (In Bash, you can do this just for the duration of the
command you are running by doing "VAR=val command".)
