本来服务器登陆好好的,不知道怎么回事,突然变慢了,debug一下,看看原因。

登陆卡在下面两句之间,不知道怎么回事。搜索了网上很多方法,都不解决问题。
debug2: key: /Users/zlpx/.ssh/id_dsa (0x0)
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password
后来发现,是DNS的捣的鬼,家里的环境没有DNS,但是有一步要检查。去/etc/ssh下把sshd_config 文件中改了一下,把 UseDNS no 设置上,登陆一切正常,反应很快了。
