scp /home/lmp/NetBeansProject/FabanGithub/faban/nightly/faban-kit-082513.tar.gz faban@202.120.40.155:/opt/

#ssh-keygen
　　#ssh-keygen -t rsa
　　# ssh root@172.24.253.2 "mkdir .ssh;chmod 0700 .ssh" (需要输入密码)
　　# scp ~/.ssh/id_rsa.pub root@172.24.253.2:.ssh/id_rsa.pub (需要输入密码)
在B上的命令:
　　# touch /root/.ssh/authorized_keys (如果已经存在这个文件, 跳过这条)
　　# cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys (将id_rsa.pub的内容追加到 authorized_keys2 中)

netstat -lpn | grep 8080

You'll get output something like this

tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      13098/java

Here my process id is 13098 and it is the process that is using port 8080

Kill the process using following command:
> sudo kill 13098

driver agent 9999 端口被占，开了多个socket，后面的workload开始时就无法再建立socket,所以要先kill掉原来的进程
