Subject:   trouble to switch off DNS

As I  do not  need DNS, I have tried to switch off this service
(I think it's enough  to map hosts over NIS)

I have  problem:. when I comment  in host.conf  bind
ipfw does not work correctly
it looks the following:

/etc > cat host.conf
# $Id: host.conf,v 1.2 1993/11/07 01:02:57 wollman Exp $
# Default is to use the nameserver first
# If that doesn't work, then try the /etc/hosts file
hosts
#bind
# If you have YP/NIS configured, uncomment the next line
nis

then I try to add rule by ipfw:

/usr/local/etc/ipfw > ipfw add 11002 pass all from 192.168.100.27
to192.168.76.65
ipfw: error: hostname ``192.168.100.27'' unknown
usage: ipfw [options]
....

when I make host.conf like this:
/etc > cat host.conf
# $Id: host.conf,v 1.2 1993/11/07 01:02:57 wollman Exp $
# Default is to use the nameserver first
# If that doesn't work, then try the /etc/hosts file
hosts
bind
# If you have YP/NIS configured, uncomment the next line
nis

Then ipfw runs real :)   :
/etc > ipfw add 11002 pass all from 192.168.100.27 to 192.168.76.65
11002 allow ip from 192.168.100.27 to 192.168.76.65

And another problem - why does ypxfr use DNS?
when I correctly build DNS service all runs fine, but when I  remove
resolv.conf
ypxfr can't take all maps and send clear request to slave server
(ypserv).
It looks the following:

/root/bin > /usr/libexec/ypxfr -d `domainname` -f -h 192.168.100.27
group.bygid
ypxfr: failed to send 'clear' to local ypserv: RPC: Unknown host
ypxfr: Exiting: Couldn't send "clear" request to local ypserv

If  I  make DNS resolver, then I have all ok!
 /usr/libexec/ypxfr -d `domainname` -f -h 192.168.100.27 group.bygid
ypxfr: Exiting: Map successfully transfered
