如果只有ssh-agent说明ssh-server还没启动,需要到/etc/init.d/ssh 执行start,如果看到sshd说明服务已启动。
ssh-server配置文件位于/etc/ssh/sshd_config,在这可定义SSH服务端口,默认22。可定义其他端口如:220,重启服务

| mhchen@mhchen-VirtualBox:~$ sudo /etc/init.d/ssh restart
ssh stop/waiting
ssh start/running, process 5990

最后确定ssh-server已正常工作。

看到ssh的tcp信息就说明ssh-server已经正常运行。
通过secureCRT可远端至服务器了。
检查服务器ip地址。
mhchen@mhchen-VirtualBox:~$ ifconfig
可以看到eth0的IP地址信息。
