При использовании ssh-авторизации по ключам, иногда бывает так что вследствии перезаписывания или удаления, теряется публичная часть ключа - id_dsa.pub (или id_rsa.pub соответственно). Однако, имея в наличии приватную часть ключа, можна восстановить публичную, используя всего одну команду.

DSA

# ssh-keygen -y -f id_dsa > id_dsa.pub

RSA

# ssh-keygen -y -f id_rsa > id_rsa.pub
