=>Hi!
=>
=>It seems, a bug exist in resolver implementation since 4.1.
=>I have a small private network with internal DNS. (no relations with
=>internet).
=>Name server is 192.168.10.130. Domain name is my.domain.com
=>
=>At host bsd.my.domain.com : 
=>
=>No local named daemon. 
=>No ipv6 in kernel. 
=>No lkm's. (All i need compiled in kernel. Other moduler removed.)
=>
=>/etc/resolv.conf
=>        #
=>	nameserver 192.168.10.130
What about with nameserver 127.0.0.1 added to resolv.conf on ns ?? What is
the
behaviour?


=>	#
=>/etc/host.conf
=>	#
=>	hosts
=>	bind
=>	#
=>/etc/hosts
=>        #
=>	127.0.0.1	locahost
=>	192.168.10.205	bsd.my.domain.com bsd
=>	192.168.10.130  ns.my.domain.com ns
=>	#
=>
=>% uname -a
=>FreeBSD bsd.my.domain.com 4.1-RELEASE FreeBSD 4.1-RELEASE #1: Thu Oct 26
=>00:54:45 NOVST 2000
=>root@bsd.my.domain.com:/usr/src/sys/compile/MY_HOST  i386
=>
=>% nslookup somehost
=>Server:  ns.my.domain.com
=>Address:  192.168.10.130
=>
=>Name:    somehost.my.domain.com
=>Address:  192.168.10.110
=>
=>%ping somehost
=>ping: cannot resolve somehost: Unknown host
=>
=>%
=>
=>Using ethereal i intecept DNS traffic generated by above 
=>mentioned commands.
=>Host send identical requests for the first and second commands.
=>NS server send identical reply for the first and second DNS requests!
=>(only transaction IDs different)
=>
=>Whats the matter?
=>
=>The same problem exists in 4.1.1-RELEASE
=>The same problem was detected while using PERL's gethostbyname.
=>
=>By.
