$ ssh -i "xxx.pem" ubuntu@xxx.xxx.xxx.com
/Users/korekyourin/.ssh/config: line 1: Bad configuration option: useroaming
/Users/korekyourin/.ssh/config: terminating, 1 bad configuration options
這時必須進入/Users/korekyourin/.ssh/config 把useroaming註解掉
vi /Users/korekyourin/.ssh/config
UseRoaming no
註解掉,變成
#UseRoaming no
這樣ssh到server 才能成功
