记录一次SecureCRT登录失败

SecureCRT登录时报错
connection closed

检查登录用户没有额外用户登录

重启服务大法，重启sshd服务，

启动时报错
/var/empty/sshd must be owned by root and not group or world-writable

报错
 /var/empty/sshd must be owned by root and not group or world-writable

发现是/var/empty/sshd授权问题，更改授权

chown -R root:root /var/empty/sshd
chmod 744 /var/empty/sshd
service sshd restart

重新登录，登录成功
