Pernah mengalami host Ubuntu tidak bisa ping ke mana pun, padahal\u00a0kita bisa browse ke mana pun?<\/p>\n

Jadi ketika saya coba ping (di\u00a0\/etc\/resolv.conf<\/strong> sudah saya isikan nameserver 8.8.8.8 dan 8.8.4.4) hasilnya:<\/p>\n

# ping detik.com\r\n ping: detik.com: Name or service not known<\/pre>\n
Tapi ketika menjalankan\u00a0nslookup<\/em>:<\/p>\n
# nslookup\r\n > detik.com\r\n ;; Got recursion not available from 8.8.8.8, trying next server\r\n Server: 8.8.4.4\r\n Address: 8.8.4.4#53\r\n\r\nNon-authoritative answer:\r\n Name: detik.com\r\n Address: 203.190.242.211\r\n Name: detik.com\r\n Address: 103.49.221.211<\/pre>\n
Hal ini sangat mengganggu kegiatan di shell prompt. Tapi setelah ke sana ke mari, akhirnya ketemu permasalahannya. Jika kita check file\u00a0\/etc\/nsswitch.conf<\/strong>, kemungkinan kita akan mendapati baris:<\/p>\n
hosts: \u00a0 \u00a0 \u00a0 \u00a0 \u00a0files mdns4_minimal [NOTFOUND=return] resolve [!UNAVAIL=return] dns<\/pre>\n
Jika iya, edit baris tersebut menjadi:<\/p>\n
hosts: \u00a0 \u00a0 \u00a0 \u00a0 \u00a0files dns<\/pre>\n
Lalu untuk memastikan tidak terjadi lagi hal seperti di atas, kita bisa menghapus\u00a0libnss-mdns<\/strong>:<\/em><\/p>\n
# apt-get remove libnss-mdns --purge\r\n Reading package lists... Done\r\n Building dependency tree\r\n Reading state information... Done\r\n The following packages will be REMOVED:\r\n libnss-mdns*\r\n 0 upgraded, 0 newly installed, 1 to remove and 2 not upgraded.\r\n After this operation, 110 kB disk space will be freed.\r\n Do you want to continue? [Y\/n]<\/pre>\n
Nah sekarang ping ke mana pun sudah tidak ada masalah:<\/p>\n
# ping detik.com -c3\r\n PING detik.com (103.49.221.211) 56(84) bytes of data.\r\n 64 bytes from 103.49.221.211 (103.49.221.211): icmp_seq=1 ttl=57 time=27.6 ms\r\n 64 bytes from 103.49.221.211 (103.49.221.211): icmp_seq=2 ttl=57 time=27.1 ms\r\n 64 bytes from 103.49.221.211 (103.49.221.211): icmp_seq=3 ttl=57 time=29.1 ms<\/pre>\n","protected":false},"excerpt":{"rendered":"
