Create key

ssh 를 사용하기 위해서는 ssh key 가 필요하다. 다음의 명령어로 간단하게 키 생성이 가능하다.

[stk@pchero21.com ~]$ ssh-keygen 

Generating public/private rsa key pair.
Enter file in which to save the key (/home/stk/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/stk/.ssh/id_rsa.
Your public key has been saved in /home/stk/.ssh/id_rsa.pub.
The key fingerprint is:
1c:fb:fa:f1:f7:f4:13:62:79:8e:57:45:b8:52:cb:a0 stk@pchero21.com
The key's randomart image is:
+--[ RSA 2048]----+
|             oo  |
|         .. o.   |
|        =.o+.o   |
|       o.X.o+    |
|        S X.     |
|         * +     |
|        . o      |
|         .       |
|                 |

키 생성 이후, ~/.ssh 디렉토리를 확인하면 생성된 key 내용들을 볼 수 있다.

$ cd ~/.ssh

$ ls -tlr
