通常是在配置无密码登陆时致使，解决方法以下：

修改本机ssh_config文件 ，将GSSAPIAuthentication yse 改成：GSSAPIAuthentication no

[root@bqh-117 ~]# sed -i 's#GSSAPIAuthentication yes#GSSAPIAuthentication no#g' /etc/ssh/ssh_config 
[root@bqh-117 ~]# sed -n 50p /etc/ssh/ssh_config
    GSSAPIAuthentication no

GSSAPIAuthentication的做用：是否容许使用基于GSSAPI的用户认证
