首先要确保两台机子直接IP能够互相ping通。
然后使用SCP命令从第一台主机向第二台主机拷贝文件
scp src linux@192.168.8.144:/home/linux/mydisk/buffer_scp_file
ssh: connect to host 192.168.8.144 port 22: Connection refused
lost connection
检查远程主机没有安装sshd
linux@linux-VirtualBox:~/mydisk/buffer_scp_file$ sshd
程序“sshd”尚未安装。您可以使用以下命令安装：
sudo apt-get install openssh-server
linux@linux-VirtualBox:~/mydisk/buffer_scp_file$ sudo apt-get install openssh-server
安装完成之后开始传输文件，这里我是传输文件夹，将文件夹下文件都传输过去，所以用了-r选项，不用该选项的话只能传文件
[root@localhost /mydisk/eclispe_workspace/java]# scp -r src linux@192.168.8.144:/home/linux/mydisk/buffer_scp_file

[root@localhost /mydisk/eclispe_workspace/java]#
到远程主机对应的目录去查看
linux@linux-VirtualBox:~/mydisk/buffer_scp_file$ ls
src
linux@linux-VirtualBox:~/mydisk/buffer_scp_file$ cd src/
linux@linux-VirtualBox:~/mydisk/buffer_scp_file/src$ ls
classloader jvm memcached rsa thread
demo logintest.txt reflect safedemo
linux@linux-VirtualBox:~/mydisk/buffer_scp_file/src$
以上是本机传文件到远程主机，下面再来试试从远程主机拷贝文件到本机
[root@localhost /mydisk/eclispe_workspace/java]# scp linux@192.168.8.144:/home/linux/mydisk/buffer_scp_file/demo.txt /mydisk/
linux@192.168.8.144's password:
demo.txt 100% 14 0.0KB/s 00:00
[root@localhost /mydisk/eclispe_workspace/java]#
本机查看相应目录
[root@localhost /mydisk]# ls
demo.txt Hadoop local_repo normandy_config software
eclispe_workspace learning_material maven_repo service
[root@localhost /mydisk]#
很实用，很简单的命令！
