Specifies the size of the TCP header in 32-bitwords. The minimum size header is 5 words and the maximum is 15 words thus giving the minimum size of 20 bytes and maximum of 60 bytes, allowing for up to 40 bytes of options in the header. This field gets its name from the fact that ...
In all cases, only packets that match expression will be processed by tcpdump. Tcpdump will, if not run with the -c flag, continue capturing packets until it is interrupted by a SIGINT signal (generated, for example, by typing your inter‐ rupt character, typically control-C) or a ...
--allow-nacl-socket-api 指定以逗号分隔的扩展ID或主机列表,以授予对TCP / UDP套接字API的访问权限。 --allow-no-sandbox-job 使沙盒流程在未分配作业对象的情况下运行。要使Chrome在RemoteApps或Citrix中运行,此标志是必需的。该标志可以降低沙盒进程的安全性,并允许它们执行某些API调用,例如关闭Windows或访问剪贴...
