まずは（５）インスタンスへの接続

SSH を使用した Linux インスタンスへの接続

いよいよ接続だ。
試しにping。
$ ping ec2-*-*9-*-*.ap-northeast-1.compute.amazonaws.com
PING ec2-*-*9-*-*.ap-northeast-1.compute.amazonaws.com (*.*.*.*): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
ダメだ。
IPに向けてもだめ。PING無効にしてあるのかな。

 sshで接続。

$ ssh -i *-key-pair-tokyo.pem ec2-user@ec2-*-*9-*-*.ap-northeast-1.compute.amazonaws.com
The authenticity of host 'ec2-*-*9-*-*.ap-northeast-1.compute.amazonaws.com (5*.*9.*.*)' can't be established.
ECDSA key fingerprint is SHA256:g+W/*.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '*.ap-northeast-1.compute.amazonaws.com,*' (ECDSA) to the list of known hosts.
