[ssh] Could not load host key 메시지 없애기

ssh 서버를 시작할 때 다음과 같이 Could not load host key 메시지가 뜨는 경우가 있습니다.

$ sudo service ssh restart [sudo] password for mine: Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_ecdsa_key Could not load host key: /etc/ssh/ssh_host_ed25519_key * Restarting OpenBSD Secure Shell server sshd Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_ecdsa_key Could not load host key: /etc/ssh/ssh_host_ed25519_key

뭐 없어도 접속은 되는데.. 보기에 거슬려서 각각의 키를 생성했습니다.

sudo ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key -N "" sudo ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -N "" sudo ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N "" sudo ssh-keygen -t ed25519 -f /etc/ssh/ssh_host_ed25519_key -N ""

sudo service ssh restart 명령으로 재시작했더니 위의 메시지가 더 이상 발생하지 않습니다.
