设置身份文件但仍然不能没有环境变量ssh

我正在尝试在crontab上设置一个scp作业，并通过控制台测试该功能。 crontab不会导入环境变量，所以我正在测试它 env -i，还要通过导入身份密钥 ssh -i。

env -i sh -c "ssh -i /home/myname/.ssh/id_rsa box hostname"

但是，这不起作用，我只是得到了 Permission denied (publickey)。我认为我的密钥设置正确。我将公钥附加到远程框的authorized_key文件中。

在这两台机器上，我在/ etc / ssh / sshd_config中设置了这些：

PubkeyAuthentication yes
RSAAuthentication yes

这是我在远程主机上的auth.log中得到的错误：

Sep 13 21:45:13 box sshd[59109]: userauth-request for user myuser service ssh-connection method publickey remote_ip <someip> remote_port 51635 attempt 1 failures 0 [preauth] session=box:57d87369.6185

EDIT2：

跑步时......

SSH_AUTH_SOCK="" ssh -vv -i /home/myuser/.ssh/id_rsa myuser@myhost

我知道了...

debug2: key: /home/myuser/.ssh/id_rsa (0x7fc5ee0d15a0), explicit
debug1: Authentications that can continue: publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/myuser/.ssh/id_rsa
debug2: we sent a publickey packet, wait for reply
debug1: Authentications that can continue: publickey
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
Permission denied (publickey).

我尝试手动将文件附加到authorized_keys，后来也尝试了ssh-copy-id。 .ssh /目录是700
