What is an anonymous user logged into a
server? If the user is anonymous, how did he
get logged in?

Do you wish to find the users, or the number
of such users, or what?

That's a start. What are you using as the
FTP server? ("man ftpd"?)

You can normally find FTP connections (of all
types) by searching "netstat -an" output for
port 21. For example:

tcp 0 0 15.170.178.192.21 209.98.249.184.15736 ESTABLISHED

"man ftpaccess" shows how to limit the number
of users of various classes ("limit"), and
how to control the logging facility ("log").

Is there some actual problem which you are
trying to solve?

Try:

netstat -a |grep 21

All Ftp connections

Also

pwget -n ananymous

grep -i ananymous /etc/passwd

Refer to ftpaccess man pages for more info.

That's a bit broad, isn't it? I'd search for
something more like ".21 ". Or don't you
ever see IP addresses like "221.212.121.21"?
