1、连接上相应的linux主机,进入到等待输入shell指令的linux命令行状态下。
2、在linux命令行下输入shell指令:route -n。
3、键盘按“回车键”运行shell指令,此时会看到系统的路由表信息。
在GUI下面,有一大把的工具可以显示网络流量,那么,命令行下面怎么办?显然办法是有的,比如,ifconfig,会有这样的输 出:
RX bytes:1224128649 (1.1 GiB) TX bytes:34114947 (32.5 MiB)
写一个脚 本,实时显示并刷新!
脚本如下
#!/bin/bash
if [ -n "$1" ]then
eth_name=$1
else
eth_name="eth0"
fi
i=0
send_o=`ifconfig $eth_name | grep bytes | awk '{print $6}' | awk -F : '{print $2}'`
recv_o=`ifconfig $eth_name | grep bytes | awk '{print $2}' | awk -F : '{print $2}'`
send_n=$send_o
recv_n=$recv_o
while [ $i -le 100000 ]do
send_l=$send_n
recv_l=$recv_n
sleep 1
send_n=`ifconfig $eth_name | grep bytes | awk '{print $6}' | awk -F : '{print $2}'`
recv_n=`ifconfig $eth_name | grep bytes | awk '{print $2}' | awk -F : '{print $2}'`
i=`expr $i + 1`
send_r=`expr $send_n - $send_l`
recv_r=`expr $recv_n - $recv_l`
total_r=`expr $send_r + $recv_r`
send_ra=`expr /( $send_n - $send_o /) / $i`
recv_ra=`expr /( $recv_n - $recv_o /) / $i`
total_ra=`expr $send_ra + $recv_ra`
sendn=`ifconfig $eth_name | grep bytes | awk -F /( '{print $3}' | awk -F /) '{print $1}'`
recvn=`ifconfig $eth_name | grep bytes | awk -F /( '{print $2}' | awk -F /) '{print $1}'`
clear
echo "Last second : Send rate: $send_r Bytes/sec Recv rate: $recv_r Bytes/sec Total rate: $total_r Bytes/sec"
echo "Average value: Send rate: $send_ra Bytes/sec Recv rate: $recv_ra Bytes/sec Total rate: $total_ra Bytes/sec"
echo "Total traffic after startup:Send traffic: $sendn Recv traffic: $recvn"
done
该脚本(假设名叫traffic)默认显示eth0的流量,如果你有多个网卡,请将网卡作为参数传进去,比如:
./traffic eth1
