[6.3] How are those daemons started?

[Gilles]

Hello

	By running "netstat -an", I notice that some daemons are running,
even though nothing is listed in either /etc/rc.conf or some
equivalent in /usr/local/etc/ :

tcp4       0      0  127.0.0.1.25
udp4       0      0  *.2727                 *.*
udp4       0      0  *.2727                 *.*
udp4       0      0  *.514                  *.*

nmap seems to only handle TCP (TCP2000 = "callbook"?) doesn't say
which application is opening those ports, and lsof | grep doesn't
return anything :-/

Are there other ways to start daemons besides listing them in
/etc/rc.conf?

Thank you.
