Anda dapat melihat bahwa saya telah menetapkan server DNS dalam konfigurasi IP saya, tetapi MENGAPA melakukan nslookup spouts
*** Can't find server name for address 172.27.0.12: Non-existent domain
*** Default servers are not available
Default Server: Unknown
Apa artinya dengan mengatakan "tidak tersedia" dan Tidak Diketahui ".
Server DNS (172.27.0.12) berfungsi dengan benar karena menjawab permintaan chj.dev.nls seperti yang diharapkan. Server DNS adalah Win2003 SP2.
Beberapa info detail:
> set debug
> chj.dev.nls
Server: UnKnown
Address: 172.27.0.12
