SSH Files Permission

使用 Win10 下的 Ubuntu 子系统的时候，把秘钥直接扔进去总是有问题，后来发现是文件的权限问题，故写个 note 记录一下。

Private / Public Key Permission

Should be 600 (Read / Write by current user ONLY).

1
2

$ sudo chmod 600 ~/.ssh/id_rsa
$ sudo chmod 600 ~/.ssh/id_rsa.pub

Known_hosts Permission

Should be 644 (Read / Write by current user & Read ONLY by other users).

1

$ sudo chmod 644 ~/.ssh/known_hosts

.ssh Directory Permission

Should be 755 (Read / Write / Execute by current user & Read / Execute by other users).

1

$ sudo chmod 755 ~/.ssh

SSH files permission resolved :)
