vnStat

vnStat is a console-based network traffic monitor for Linux and BSD that keepsa log of network traffic for the selected interface(s). It uses the networkinterface statistics provided by the kernel as information source. This meansthat vnStat won't actually be sniffing any traffic and also ensures light useof system resources. However, in Linux at least a 2.2 series kernel is required.

This program is open source / GPL'ed and can be installed either as root oras a single user. Better instructions are included in the README. Feel freeto send comments byemail(remove the spamfilter) or try contacting me from irc (Vergo @ IRCNet).A discussion forum is also available.Announcements about new versions can be obtained by subscribing to the vnStatproject atfreshmeat.net.

Features

  • quick and simple to install and get running
  • gathered statistics persists through system reboots
  • can monitor multiple interfaces at the same time
  • several output options
    • summary, hourly, daily, monthly, weekly, top 10 days
    • optional png image output (using libgd)
  • months can be configured to follow billing period
  • light, minimal resource usage
  • same low cpu usage regardless of traffic
  • can be used without root permissions
  • online color configuration editor

缓存 网络协议 算法
深入TCP协议——tcp_tw_reuse和tcp_tw_recycle
我们已经知道TCP四次挥手中，主动方在收到被动方的FIN数据包之后会进入TIME_WAIT状态等待2MSL的时间后才进入CLOSED。在 Linux 操作系统下，TIME_WAIT 状态的持续时间是 60 秒，这意味着这 60 秒内，客户端一直会占用着这个端口，这是有一定的开销的。如果如果主动关闭连接方的 TIME_WAIT 状态过多，占满了所有端口资源，则会导致无法创建新连接。
