Defcon 20 CTF VM图像

Question

我似乎无法获得这些服务。使用VM图像融合启动下载的VMWare (在MacOSX10.8.2上)

ifconfig返回以下内容：

em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

但我似乎无法连接到on 20:c7f:2012:12：：7的任何形式的服务:例如，能够发送/recv到/从在on 20:c7f:2012:12:7，端口6941上运行的semem服务。

我尝试过一些基本的东西，比如ping6和telnet -6，netcat/nmap，还有python，但是它们似乎无法连接(超时)。

另一个*：服务运行良好。

我从谷歌搜索结果中看到，dc20:c7f:2012:12::7:6941意味着服务绑定到ipv6地址‘ie 20:c7f:2012:12：：7’的接口，即。(虚拟)网络接口em1，它也是由另一个地址所知，因此，为了能够与服务通信，我首先必须创建一个套接字，将套接字绑定到与接口相关的这个地址，然后从这个接口发送到服务，但在代码中尝试似乎仍然不起作用。

请给我指点？希望有一些Python中的套接字编程。

在/etc/rd.conf中，用下面的ifconfig_em1_ipv6="inet6 dc20:c7f:2012:12::7 prefixlen 64"替换该行：ifconfig_em1="inet6 dc20:c7f:2012:12::7 prefixlen 64"

那就重新开始。

[root@dc20 ~]# ping6 -c 3 dc20:c7f:2012:12::7

完全有效。
