SSH logon failure due to permission error

Reference:http://blog.csdn.net/ucan23/article/details/49850365

Yesterday due to the deployment of the developer's service to the/OPT/BH directory, and Ln-s/opt/bh/var, and then modify the permissions, it should be performed:

Chown-r Amos:amos/opt/amos

But the error has been performed:

Chown-r Amos:amos/var/amos

Then SSH login error:

[[email protected] shell]# ssh [email protected]

Ssh_exchange_identification:connection Closed by remote host

The reason for this is the permission error:

Chown-r root:root/var/empty/sshd chmod 744/var/empty/sshd service sshd restart

But now you can not login, how to do?

Fortunately, we deployed the Som-zagend service and executed the following two commands on other servers in the intranet, and then logged in.
