vim graph.c

Top20修改為Top100 (有三個)

Counter < 21修改為Counter < 101 (有兩個)

6.安裝bandwidthd

cd /usr/local/src/bandwidthd-2.0.1
./configure
make install

◎如有發生libpcap錯誤，請安裝libpcap

rpm -i http://isoredirect.centos.org/centos/5/os/i386/CentOS/libpcap-devel-0.9.4-8.1.i386.rpm
rpm -i http://isoredirect.centos.org/centos/5.1/os/i386/CentOS/libpcap-devel-0.9.4-11.el5.i386.rpm
