ssh connect to host port : Connection refused

 问题：ssh请求被拒绝

pruce@~$ ssh [email protected]
ssh: connect to host 10.60.100.172 port 22: Connection refused

 解决一：

#查看ssh是否正常安装
pruce1@~$ ps -ef|grep ssh
pruce1     3826   3743  0 11:56 pts/1    00:00:00 grep --color=auto ssh

 新Ubuntu没有安装openssh-server

#安装服务
sudo apt-get install openssh-server

pruce1@~$ ps -ef|grep ssh
root       3589      1  0 11:51 ?        00:00:00 /usr/sbin/sshd -D
root       3678   3589  0 11:52 ?        00:00:00 sshd: pruce1 [priv] 
pruce1     3742   3678  0 11:52 ?        00:00:00 sshd: pruce1@pts/1  
pruce1     3826   3743  0 11:56 pts/1    00:00:00 grep --color=auto ssh

 ssh链接正常，OK。
