工作中，通过ftp反复上传下载大文件来测试路由器的稳定性。
一共有两个脚本：
1 ftp.sh，主要调用这个脚本，内容如下，
----------------------------------------------------------------------------------------------------------
#!/bin/bash
# script function:
# 1 run ftp to upload and download file every fixed minutes;
# 2 check host online or not before every ftp loop;

2 ftp_reset.sh，顾名思义，就是重置ftp进程的脚本，因为ftp在实际运行中经常出现挂死现象，解决办法是在centos的crontab下添加定时任务，每隔3分钟运行一次ftp_reset.sh脚本，可以在很大程度上避免ftp程序挂死的问题。
