Sera que alguem poderia me ajudar???
Estou tentando montar um DNS usando Fedora Core 2. Acho que já fiz tudo que podia, mas ainda está
dando problema.
Configurei o arquivos, em /etc e /var/named/chroot/etc:
named.conf
// generated by named-bootconf.pl
options {
directory "/var/named";
listen-on { 127.0.0.1; 192.168.0.0/24; 192.168.0.0; };
allow-query { 192.168.0.0/24; };
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};
//
// a caching only nameserver config
//
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
zone "teste.lab.br" IN {
type master;
file "teste.lab.br";
};
zone "0.168.192.in-addr.arpa" IN {
type master;
file "teste.lab.br.rev";
};
Configurei os arquivos, em /var/named e /var/named/chroot/var/named
teste.lab.br
$TTL 86400
$ORIGIN teste.lab.br.
@ IN SOA fiona.teste.lab.br. root.fiona.teste.lab.br. (
2005033101;
3H;
15M;
1W;
1D);
IN NS fiona.teste.lab.br.
IN MX mail.teste.lab.br.
fiona IN A 192.168.0.1
gerencia IN A 192.168.0.10
web IN A 192.168.0.53
mail IN A 192.168.0.88
aker IN A 192.168.0.254
E também o arquivo,
teste.lab.br
$TTL 86400
$ORIGIN 0.168.192.in-addr.arpa.
@ IN SOA fiona.teste.lab.br. root.fiona.teste.lab.br. (
2005033101;
28800;
14400;
3600000;
86400);
IN NS fiona.teste.lab.br.
IN MX mail.teste.lab.br.
1 IN PTR fiona.teste.lab.br.
10 IN PTR gerencia.teste.lab.br.
53 IN PTR web.teste.lab.br.
88 IN PTR mail.teste.lab.br.
254 IN PTR aker.teste.lab.br.
Ao dar o comando nslookup, a seguinte resposta é obtida:
[root@fiona root]# nslookup mail.teste.lab.br
Server: 192.168.0.1
Address: 192.168.0.1#53
** server can't find mail.teste.lab.br: SERVFAIL
[root@fiona root]# nslookup mail
Server: 192.168.0.1
Address: 192.168.0.1#53
** server can't find mail: NXDOMAIN
Quando dou o comando dig:
[root@fiona root]# dig 192.168.0.1
; <<>> DiG 9.2.3 <<>> 192.168.0.1
;; global options: printcmd

Mais ainda, quando dou o comando netstat:
[root@fiona root]# netstat -an | grep 53
tcp 0 0 192.168.0.1:53 0.0.0.0:* OUÃA
tcp 0 0 127.0.0.1:53 0.0.0.0:* OUÃA

O que eu faço???? Será que alguém poderia me ajudar?
Ps. NÃO TENHO FIREWALL INSTALADO NA MAQUINA, REMOVI O IPTABLES.
RISOS... E PRA FINALIZAR, A BENDITA CONEXÃO COM SSH QUE FICA CAINDO DIREEEEETO!!! RISOS....
SERÁ QUE TEM SOLUÇÃO, OU DEVO MANDAR O CARA QUE TA MEXENDO (EU) PRA....... RISOS... .
MAAAAAIS UMA COISA.... PRA FORA O DNS FUNCIONA:
[root@fiona root]# nslookup www.usp.br
Server: 192.168.0.1
Address: 192.168.0.1#53
Non-authoritative answer:
Name: www.usp.br
Address: 143.107.254.11
AGRADEÇO DESDE JÁ!!!!!!
