iftop命令过滤器使用参数

在baidu和google上找了N篇文章,都没有一篇是介绍怎么用iftop的-f参数,全部都是说“-f这个暂时还不太会用,过滤计算包用的”,最后,终于找到了使用方法,介绍如下:

iftop accepts pcap-filter formatted filters on the commandline with the -f flag. Below is a table of some of the filers you might want to use with iftop:

dst host host src host host
dst net net src net net
dst port port src port port
dst portrange start-end src portrange start-end
gateway gateway
ip proto protocol

For example, to view only traffic going from your local machine to www.srcloft.com over eth0, you could run:

iftop -i eth0 -f “dst host www.srcloft.com

Or to see only ssh traffic over wlan0:

iftop -i wlan0 -f “dst port 22″
其它的使用方法自己上baidu或google上找吧,此处不做重复介绍了!
