最近看到vmlinux大神介绍了一款网络查看工具,感觉很好用,下面进行简要摘录:
iptraf-ng 可以方便查看当前服务器网络状况:CentOS 7.0,采用了衍生版本iptraf-ng 。
iptraf-ng -h
usage: iptraf-ng [options]
or: iptraf-ng [options] -B [-i <iface> | -d <iface> | -s <iface> | -z <iface> | -l <iface> | -g]
-h, --help show this help message
-i <iface> start the IP traffic monitor (use '-i all' for all interfaces)
-d <iface> start the detailed statistics facility on an interface
-s <iface> start the TCP and UDP monitor on an interface
-z <iface> shows the packet size counts on an interface
-l <iface> start the LAN station monitor (use '-l all' for all LAN interfaces)
-g start the general interface statistics
-B run in background (use only with one of the above parameters
-f clear all locks and counters
-t <n> run only for the specified <n> number of minutes
-L <logfile> specifies an alternate log file
简要步骤:
“iptraf -g” 显示每一个网卡上的流量:
“iptraf -d eth0” 显示指定网卡上的流量统计,总体流量、流入量、流出量、以及按协议分类的流量统计:
“iptraf -s eth0” 统计各port的流量:
“iptraf -i eth0” 查看远程主机端口:
“iptraf -i eth0” 的输出分为两个窗口,上面是TCP socket pairs,下面是UDP。我们根据端口号 使用 lsof 可以找到对应的进程号;
