SecureCRT 连接本地linux虚拟机

SecureCRT 连接本地linux虚拟机

通过ssh连接到虚拟机，首先需要在虚拟机中安装openssh-client，如未安装通过命令

mhchen@mhchen-VirtualBox:~$ sudo apt-get install openssh-server
[sudo] password for mhchen:

openssh-server is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 323 not upgraded.
mhchen@mhchen-VirtualBox:~$

提示已经安装过openssh-client.

检查sshserver是否启动：

mhchen@mhchen-VirtualBox:~$ ps -e |grep ssh
2225 ?        00:00:00 ssh-agent
5580 ?        00:00:00 sshd
5651 ?        00:00:00 sshd
5714 ?        00:00:00 sshd
5846 ?        00:00:00 sshd
5887 ?        00:00:00 sshd
mhchen@mhchen-VirtualBox:~$

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
mhchen@mhchen-VirtualBox:~$

最后确定ssh-server已正常工作。

mhchen@mhchen-VirtualBox:~$ netstat -tpl

mhchen@mhchen-VirtualBox:~$

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。
