一.基于口令验证

[root@zyl ~]# cat ~/.ssh/known_hosts

cat: /root/.ssh/known_hosts: No such file or directory

[root@zyl ~]# ls -l ~/ -a

dr-xr-xr-x. 32 root root     4096 Jun 28 17:25 ..

drwx-wx-wx.  2 root root     4096 Jun 19 14:06 044dir

-rw--w--w-.  1 root root        0 Jun 19 14:09 044file

-rw-------.  1 root root     1119 Jun  8 19:36 anaconda-ks.cfg

。。。。。。。。。。####没有ssh

[root@zyl ~]#  ssh -p22 root@192.168.21.132 ##ssh -p端口号 远程主机用户@远程主机ip
