fwknop stands for "Firewall Knock Operator" and is an upcoming piece of software that will be released at the DEFCON 12 conference in July, 2004 in Las Vegas. fwknop implements network access controls (via iptables) based on a flexible port knocking mini-language, but with a twist it combines port knocking and passive operating system fingerprinting to make it possible to do things like only allow, say, Linux-2.4/2.6 systems to connect to your SSH daemon. fwknop supports shared, multi-protocol port knock sequences along with both relative and absolute timeouts, and coded port knock sequences encrypted with the Rijndael block cipher.

XHTML标准参考手册,XHTML是The Extensible HyperText Markup Language可扩展标识语言的缩写。目前推荐遵循的是W3C于2000年1月26日推荐XML1.0(参考http://www.w3.org/TR/xhtml1)。XML虽然数据转换能力强大,完全可以替代HTML,但面对成千上万已有的站点,直接采用XML还为时过早。因此,我们在HTML4.0的基础上,用XML的规则对其进行扩展,得到了XHTML。简单的说,建立XHTML的目的就是实现HTML向XML的过渡。
