echo "$TIMESTAMP,$RX_BYTES,$TX_BYTES" >> $OUTPUT_FILE 保存上述脚本为monitor_traffic.sh,并添加执行权限: chmod +x monitor_traffic.sh 编辑crontab任务计划,每小时执行一次该脚本: crontab -e 添加以下行: 0 * * * * /path/to/monitor_traffic.sh 这样,每小时的流量数据就会自动记录到/var/log/net...
1、官方说明: iftop: display bandwidth usage on an interface.iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. 1.1、Iftop工具主要用来显示本机网络流量情况及各相互...

在早期的Linux发行版本里几乎所有的网络服务都是network服务,从RHEL7开始红帽官方建议采用NetworkManager的“方式”配置网络,而不建议再使用network服务传统的方式配置网络。 原因: 网络是非常复杂的,需要配置的网络相关的参数非常多。早期配置网络的方法,几乎只有创建网卡配置 ...

Some of the commands, show the bandwidth used by individual processes. This makes it easy to detect a process that is overusing network bandwidth. The tools have different mechanisms of generating the traffic report. Some of the tools like nload read the "/proc/net/dev" file to get traffic...
在“Network Traffic:Data Sent”图表 中显示局域网中一台机器发送大量的数据包,这台机器的IP地址和MAC也能找到。基本能断定这台机器中了病毒在发送大量的UDP包,从而造成了广播风暴, 导致网络性能急速下降,如图19所示,是Ntop捕捉到的随机发送的地址列表。找到故障节点后,随后根据MAC-IP-墙点的对应,及时将这台机器...

Routers in particular should always include some kind of firewall to keep undesirable traffic out of your network. A firewall is a software and/or hardware configuration that usually sits on a router between the Internet and a smaller network, attempting to ensure that nothing “bad” from the...
