BT是based on Ubuntu, 所以使用起來沒有太大的難度, 剩下的就是針對各個軟體學習如何使用了.
我常用的hping2, hping3, Nessus, nmap, netcat, tcpreplay, tcpdump, wireshark...等等都有內建於其中, 然而還有更多工具是我沒用過的, BT果然是一套好的distro來測試網路設備或系統漏洞, 但是若拿它來做非法的事情, 可就不是我推薦的了.

The CentOS team is pleased to announce the immediate availability of CentOS-6.0 for i386 and x86_64 Architectures.
CentOS-6.0 is based on the upstream release EL 6.0 and includes
packages from all variants. All upstream repositories have been combined into one, to make it easier for end users to work with.
There are some important changes to this release compared with the previous versions of CentOS and we highly recommend reading this announcement along with the Release Notes.
There are no CD images being released with CentOS-6, however we have some CD variants in the pipeline.
Since upstream has a 6.1 version already released, we will be using a Continous Release repository for 6.0 to bring all 6.1 and post 6.1 security updates to all 6.0 users, till such time as CentOS-6.1 is released itself.
LiveCDs and LiveDVDs for i386 and x86_64 will be released the
next few days. These will bring in the ability to directly install from the live media.
There will also be a minimal install CD, that would bring up a base
machine with just enough content to have a usable platform.
In order to bring back the CentOS-4 Server CD style single iso image, an LWS variant of the main distro will be created.
And now: Have fun.
"--port=0" It means Listen oninstead of the standard DNS port (53). Setting this to zero completely disables DNS function, leaving only DHCP and/or TFTP.
1. Prepare: Squid 3.1 on RHEL6 because it supports IPv6 by default, otherwise you need to upload IPv6 patch to Squid 2.x version.
2. Configure IPv6 in Squid 3.1:
In /etc/squid/squid.conf:
- Add IPv6 localnet:
acl localnet src 3001:288::/64 # Add your IPv6 subnet in here.
- Allow localnet:
http_access allow localnet
-Restart Squid:
# /etc/init.d/squid restart; chkconfig squid on
3. Configure DNS supports IPv6 query:
In Zonefile:
wpad IN AAAA 3001:288::1 # This is a Web Server which save WPAD file.
proxy IN AAAA 3001:288::2 # This is a Proxy Server.
4. Configure WPAD file:
function FindProxyForURL(url, host) {
if (host == "localhost" ||
host == "localhost.localdomain" ||
host == "127.0.0.1" || host == "[3001:288::3]" || host == "10.10.2.2" ) {
return "DIRECT";
// Requests to localhost, 3001:288::3, and 10.10.2.2 will not redirect to proxy
}That's all.
// All other requests go through the local squid proxy
return "PROXY proxy.example.com:8080; DIRECT";
}
