Saya memiliki alamat IP STATIK di jaringan saya.
Saya dapat melakukan ping ke salah satu server Google:
root@napajohn:~# ping 74.125.224.72
PING 74.125.224.72 (74.125.224.72) 56(84) bytes of data.

64 bytes from 74.125.224.72: icmp_req=5 ttl=49 time=76.6 ms
Tapi saya tidak bisa menyelesaikan nama host apa pun:
root@napajohn:~# ping www.google.com
ping: unknown host www.google.com
Saya harus mencatat bahwa saya berada di belakang proxy, tetapi itu seharusnya tidak mempengaruhi tidak menyelesaikan nama. Saya juga tidak bisa menyelesaikan nama proxy saya.

Saya telah menghabiskan beberapa jam untuk mencari tahu penyebab potensial dari masalah ini, tetapi dari apa yang telah saya baca dan coba sejauh ini, semuanya tampak normal (seperti apa yang orang sarankan di utas lain sudah baik / ada di mesin saya), kecuali bahwa saya tidak memiliki file /etc/named.conf saya juga tidak memiliki file /etc/resolv.conf. Saya bisa membuatnya (bagaimana saya tahu apa yang harus dimasukkan?) Tapi saya tidak berpikir itu akan menyelesaikan masalah. Saran?
Saya sedang berlari:
