今天連接linux時居然連不上，報錯信息是：

Connecting to 10.10.10.116:22...

Connection established.

To escape to local shell, press ‘Ctrl+Alt+]‘.

Connection closed by foreign host.

Type `help‘ to learn how to use Xshell prompt.

[C:\Users\huazhixu]$

查了一下終於找到了解決辦法，只需要一些命令就可以了：

[[email protected] network-scripts]# cd /etc/ssh

[[email protected] ssh]# ll

總用量 268

-rwxrwxr-x. 1 root root 242153 3月 20 2014 moduli

-rwxrwxr-x. 1 root root 2123 3月 20 2014 ssh_config

-rwxrwxr-x. 1 root root 4432 10月 11 15:56 sshd_config

-rwxrwxr-x. 1 root ssh_keys 227 10月 11 13:10 ssh_host_ecdsa_key

-rwxrwxr-x. 1 root root 162 10月 11 13:10 ssh_host_ecdsa_key.pub

-rwxrwxr-x. 1 root ssh_keys 1679 10月 11 13:10 ssh_host_rsa_key

-rwxrwxr-x. 1 root root 382 10月 11 13:10 ssh_host_rsa_key.pub

[[email protected] ssh]# chmod 644 ./*

[[email protected] ssh]# chmod 600 ssh_host_rsa_key

[[email protected] ssh]# chmod 755 .

[[email protected] ssh]# systemctl restart sshd.service

[[email protected] ssh]#

完成後在重新連接就行了。
