 글 시작에 앞서 다음 블로그에 대한 내용을 보고 참고했다.

1. IP 확인

ifconfig

 

result:

enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet xxx.xxx.xx.xx  netmask 255.255.255.0  broadcast xxx.xxx.xx.255
        inet6 fe80::7285:c2ff:fe69:98df  prefixlen 64  scopeid 0x20<link>

        loop  txqueuelen 1000  (Local Loopback)

 enp2s0에서 inet xxx.xxx.xx.xx로 현재 내 유동 IP를 확인할 수 있다.

 

2. netplan 설정 파일 수정

cd /etc/netplan
sudo vim 01-network-manager-all.yaml

Before:

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

After:

# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
  ethernets:
    enp2s0:
      addresses:
        - xxx.xxx.xx.xx/24
      gateway4: xxx.xxx.xx.254
      nameservers:
        addresses: [168.126.63.1]

 

3. netplan 적용

sudo netplan apply

 

4. IP 확인

 

5. ssh로 접속 환인

ssh kimsangmin@xxx.xxx.xx.xx
