在Mac电脑上安装了一些东西后,结果ssh连不上了,ping ip地址又可以。使用ssh localhost命令老是提示Connection closed by ::1。使用ssh -v localhost,提示:

OpenSSH_6.9p1, LibreSSL 2.1.8

debug1: /etc/ssh/ssh_config line 21: Applying options for *

总是链接不上,只能去看日志,结果提示

error: Permissions 0644 for ‘/etc/ssh/ssh_host_dsa_key‘ are too open. : 31 time(s)
error: Permissions 0644 for ‘/etc/ssh/ssh_host_rsa_key‘ are too open. : 31 time(s)
error: bad permissions: ignore key: /etc/ssh/ssh_host_dsa_key : 31 time(s)
error: It is recommended that your private key files are NOT accessible by others. : 62 time(s)
error: bad permissions: ignore key: /etc/ssh/ssh_host_rsa_key : 31 time(s)
error writing /proc/self/oom_adj: Operation not permitted : 54 time(s)

然后在终端使用命令:‘sudo chmod 600 /etc/ssh/ssh_host_?sa_key‘,终于可以连上了。这里记录一下,防止以后遇到同样的问题。
