笔记：Metasploit, The Penetration Tester's Guider
内容：在Backtrack5中使用msfconsole时出现Pcaprubmodule is not available的错误
在Backtrack5中使用msfconfole的scanner/portscan/syn时出现错误
The Pcaprub module is not available: no such file to load -- pcaprub
[-] Auxiliary failed: RuntimeError Pcaprub not available
[-] Call stack:

[*] Auxiliary module execution completed
这是Backtrack5的一个Bug，详见http://redmine.backtrack-linux.org:8080/issues/148 。
解决方法如下：
打开/opt/framework3/scripts/setenv.sh，添加pcaprub的路径：
RUBYLIB="...:/opt/framework3/ruby/lib/ruby/site_ruby/1.9.1/i686-linux:/opt/framework3/msf3/external/pcaprub;
