Ubuntu 설치 이후 interface가 dhcp로 설정되어 있으면 telnet접속이 불편하다.
이 때 /etc/network/interfaces 파일을 수정한다.

# and how to activate them. For more information, see interfaces(5).# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp
“iface eth0 inet dhcp”를 삭제하거나 주석처리하고 IP를 설정해 준다.

설정이 끝난 다음 network서비스를 다시 시작한다.
sudo service networking restart
