ssh の公開鍵の設定めんどい

More than 5 years have passed since last update.

ssh ログインをパスフレーズ使ってログインするために、公開鍵を渡すときの話

×

$ cat "~/.ssh/id_rsa.pub" | ssh user@hostname "cat >> .ssh/authorized_keys"
  • 長い
  • .ssh ディレクトリないときもっと面倒 (要 mkdir .ssh)
  • authorized_keys が新規作成された時も面倒 (要 umask 077)

$ ssh-copy-id user@hostname
  • 短い
  • このためだけに覚えるの面倒
  • ポート番号を 22 から変更していると無理っぽい? → 下の yaotti 氏のコメント参照
