Look into Proftp for all ftp services. http://www.proftpd.net/

man inetd 

or check into xinetd http://www.synack.net/xinetd/

You may want to set up ssh as a means of access to the server for
yourself.  If you do want to allow access via telnet/ssh for users,
you may want to look at "jail" (man jail).

limit system resources via login classes.  Is something like that
what you mean? "man 5 login.conf" should give some details
