Maximum segment lifetime is the time a TCP segment can exist in the internetwork system. It is arbitrarily defined to be 2 minutes long. The Maximum Segment Lifetime value is used to determine the TIME_WAIT interval (2*MSL) The command that can be used on many Unix systems to determine the TIME_WAIT interval is: ndd -get /dev/tcp tcp_time_wait_interval 60000 (60 seconds) is a common value. On FreeBSD systems this description and value can be checked by the command sysctl: sysctl -d net.inet.tcp.msl sysctl net.inet.tcp.msl which gets the result:

  • Maximum segment lifetime is the time a TCP segment can exist in the internetwork system. It is arbitrarily defined to be 2 minutes long. The Maximum Segment Lifetime value is used to determine the TIME_WAIT interval (2*MSL) The command that can be used on many Unix systems to determine the TIME_WAIT interval is: ndd -get /dev/tcp tcp_time_wait_interval 60000 (60 seconds) is a common value. On FreeBSD systems this description and value can be checked by the command sysctl: sysctl -d net.inet.tcp.msl sysctl net.inet.tcp.msl which gets the result: net.inet.tcp.msl: Maximum segment lifetime net.inet.tcp.msl: 30000 On some Linux systems, this value can be checked by either of the commands below: sysctl net.ipv4.tcp_fin_timeout cat /proc/sys/net/ipv4/tcp_fin_timeout (en)
  • 最大段寿命 是一个 TCP 分段可以存在于互联网系统中的最大时间。它被任意地定义为两分钟长。 最大段寿命的值用来确定 TIME_WAIT 周期(最大段寿命的两倍) 以下的命令在大部分 UNIX 系统下可以用来确定 TIME_WAIT 周期: ndd -get /dev/tcp tcp_time_wait_interval 返回的结果以毫秒计数。60000(60 秒)是常见的取值。 在 BSD 系统(例如 OS X、FreeBSD)上可以使用 sysctl 查看这项的描述和数值: sysctl -d net.inet.tcp.msl # OS X 不可用 sysctl net.inet.tcp.msl 得到的结果将会是: net.inet.tcp.msl: 最大段寿命 # Maximum Segment Lifetime net.inet.tcp.msl: 30000 在一些 Linux 系统上,这个数值可以用这两个命令中的一种确认: sysctl net.ipv4.tcp_fin_timeout cat /proc/sys/net/ipv4/tcp_fin_timeout (zh)
