 # SSH
 
+[link](https://walkingplow.tistory.com/72)  
+I had an issue with sshing to hotcake / cake after regenerating ssh key pair.  
+`ssh-copy-id -i ~/.ssh/id_rsa.pub jun@hotcake` this helped.  
+This copy public ssh key to server's `authorized_keys` folder which is located under server's `~/.ssh`.  
+After that, I can ssh into server just by `ssh hotcake` or `ssh cake`. For this, I guess I need to edit
+configure file `config` under Mac's `~/.ssh`.  
+For example,  
+```
+Host cake
+  HostName cake
+  User junsukha
+```
