локальный идентификатор пользователя: GregD идентификатор удаленного пользователя: GregTD
Я знаю, как настроить authorized_keys, чтобы я мог войти в систему как GregD. но мне нужно подключиться к серверу как GregTD, и, несмотря на то, что я добавил мои авторизованные_ключи в .ssh/ (да, у меня правильно установлены разрешения), и даже после успешного запуска ssh-copy-id, меня все равно спрашивают пароль когда я пытаюсь ssh GregTD @ foo
Список удаленных .ssh:
GregTD@foo $ ls -alh

Что я сделал:
$ ssh-copy-id GregTD@foo
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/GregD/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
GregTD@foo's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'GregTD@foo'"
and check to make sure that only the key(s) you wanted were added.
$ ssh -v GregTD@foo

GregTD@foo's password:
Запустил ssh -vv дважды, один раз как GregTD (неудача), и один раз как GregD (успех)
Было два различия: Не удалось:
debug1: rekey after 4294967296 blocks
debug2: key: /Users/m082166/.ssh/id_rsa (0x7fef96e12320)
Успех:
debug1: rekey after 4294967296 blocks
debug2: key: /Users/m082166/.ssh/id_rsa (0x7fb600e0a420)
...
debug1: Offering RSA public key: /Users/m082166/.ssh/id_rsa
debug2: we sent a publickey packet, wait for reply
debug1: Server accepts key: pkalg rsa-sha2-512 blen 279
2-й успех (хотел посмотреть, изменился ли ключ. Сделал)
debug2: key: /Users/m082166/.ssh/id_rsa (0x7fb600e0a420)
Это полезно? То, что я пытаюсь сделать, должно работать, да?
