tcpdump手册
Tcpdump打印出在某个网络界面上，匹配布尔表达式expression的报头。 输出时如果 指定``[|proto]''，tcpdump可以指出那些捕捉量过小的数据报，这里的proto是截断 如果报文中IP的目的地址域是host，则逻辑为真。host既可以是地址，也可以是主机名。

tcp/ip hijacking
the host machine receives the spoofed packet and, believing it came from the victim’s this effect can be accomplished with tcpdump, awk, and a command-line [ip proto] tcp (6). [ip ttl] 255. [ip tos] 00. [ip frag offset] 0000
tcpdump expressions
host ip, either source or destination of the packet is host ether host mac, either the ethernet source or destination address is ehost ip proto protocol, true if the packet is an ip packet (see ip(4p)) of protocol type protocol.
