解决 SSH Connection closed by foreign host 问题

Xshell 报错 :

1.有可能是IP和别人冲突，改一下IP就好了

2.也有可能是文件权限的问题。改一下：

 cd /etc/ssh/
 chmod  ssh_host_*
 chmod  *.pub

3、也有可能是防火墙的问题

/etc/init.d/iptables status    //先看一下防火墙状态
chkconfig iptables off       //关闭的命令

或者：

#停止firewall
systemctl stop firewalld.service

#禁止firewall开机启动
systemctl disable firewalld.service
