Hello to Everybody I've configured an (only!!) internal experimental DNS (home.net) for my LAN. the machine (FC3, bind 9.2.5 rel.3) is called fedora3.home.net (192.168.0.50) I've added a W2000 (zenone.home.net, 192.168.0.20) as an experimental client pointing to fedora3 as DNS. here's my /var/named/chroot/etc/named.conf file: options { directory "/var/named"; dump-file "/var/named/data/cache_dump.db"; statistics-file "/var/named/data/named_stats.txt"; }; acl "mylan" { 127/8; 192.168.0.0/24; }; controls { inet 127.0.0.1 allow { localhost; } keys { rndckey; }; }; view "inside" { match-clients { "mylan"; }; recursion yes; zone "." IN { type hint; file "named.ca"; }; zone "0.168.192.in-addr.arpa" IN { type master; file "homelan.db"; }; zone "home.net" { type master; file "db.home.net.inside"; }; }; include "/etc/rndc.key"; that's my homelan.db for the reverse lookups: $TTL 86400 @ IN SOA 0.0.168.192.in-addr.arpa. root.fedora3.home.net. ( 2005101501 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minimum IN NS 0.0.168.192.in-addr.arpa. 1 IN PTR fedora3.home.net. 2 IN PTR zenone.home.net. ;EOF and that's is my db.home.net.inside $TTL 86400 @ IN SOA home.net. root.fedora3.home.net. ( 2005101501 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minimum ; Name Servers IN NS fedora3.home.net. ; Mail Server for Domain IN MX 10 fedora3.home.net. ; Public Servers fedora3 IN A 192.168.0.50 ; Private Clients on the LAN zenone IN A 192.168.0.20 ;EOF the problems are the following: (1) the command host fedora3 (or host zenone) fails with the following message: Host fedora3 not found: 2(SERVFAIL) host fedora3.home.net (or host zeone.home.net) works OK instead. (2) the command nslookup zenone.home.net works OK the command nslookup 192.168.0.20 fails with the following error message: Server: 192.168.0.50 Address: 192.168.0.50#53 ** server can't find 20.0.168.192.in-addr.arpa: NXDOMAIN thanks a lot in advance for your reply bye Fabiano
