howto secure remote network ssh

0. 기존에 만든 키가 있는지 확인

# 키 저장 위치로 이동
cd ~/.ssh

# 디렉터리 확인
dir

# result
# -a---        2024-04-26  오후 9:50           1876 id_rsa
# -a---        2024-04-26  오후 9:50            406 id_rsa.pub

# id_rsa.pub 파일이 존재하면 미리 생성해둔 키가 있는 것
# 키가 없다면 다음 1번부터 진행

1. 공개키-개인키 생성

   • 커맨드라인

   ssh-keygen
   

   • 콘솔 Output

   Generating public/private rsa key pair.
   Enter file in which to save the key (/home/path/.ssh/id_rsa):
   Created directory '/home/path/.ssh'.
   Enter passphrase (empty for no passphrase):
   Enter same passphrase again:
   Your identification has been saved in /home/path/.ssh/id_rsa
   Your public key has been saved in /home/path/.ssh/id_rsa.pub
   The key fingerprint is:
   SHA256:gYvoovB17rxedtSrKNblhVQut2llh7N18uegR+2Z10M tuska@DESKTOP-6TUO5I7
   The key's randomart image is:
   +---[RSA 3072]----+
   |                 |
   |       .    .    |
   |      . .  o   . |
   |   . . . .o.o * +|
   |  . . . S..+.= O.|
   | .       .o =.+E+|
   |o . . ..oo.o.o.+=|
   |oo . +oo.o... .+=|
   |. .  +*o. .  .  o|
   +----[SHA256]-----+
   

2. 생성한 공개키 Server로 전송하기

type $env:[public key path] | ssh [username]@[remote-host] "cat >> .ssh/authorized_keys"

3. ssh 접속

ssh [username]@[remote-host]
