DNS 직접수정

/etc/resolv.conf 을 수정하면 안된다.  

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search RT-DHCP

/etc/resolvconf/resolv.conf.d/head 

  • base – 다른 설정 파일들을 찾을수 없을때 사용된다.
  • head – resolv.conf 파일의 헤더에 사용되는 DNS 서버는 항상 목록의 첫 번째인지 확인하는데 사용할 수 있다.

공유기의 WAN :  현재는 자동으로 잡아두었다.
