How to know traffic to a specific port in linux
提问by uday kiran
I am looking to find the traffic through a specific port for a time frame. For example, traffic through 3306 port for 10 seconds. Is there a way to find this information?
我正在寻找通过特定端口的时间范围内的流量。例如，通过 3306 端口的流量持续 10 秒。有没有办法找到这些信息？
I see that "/sbin/ifconfig eth0 05" can be used to get information on total bytes but I am looking to find information about specific port's traffic.
我看到“/sbin/ifconfig eth0 05”可用于获取有关总字节数的信息，但我正在寻找有关特定端口流量的信息。
Thanks in advance,
提前致谢，

tcpdump -i eth0 -s 1500 port 3306

sudo iftop -P -n -N -m 10M -f 'port 3260'
- -P display ports
- -n no hostname lookup
- -N display ports not service names
- -m limit for bandwidth scale
- -f filter rule
- -P 显示端口
- -n 不查找主机名
- -N 显示端口而不是服务名称
- -m 限制带宽规模
- -f 过滤规则
