In case anyone's trying to figure out where I got 64B from:
1. 3 * sizeof(void *) + sizeof(std::pair<unsigned, void *>)
2. 3 * 8B + 16B
3. 48B !? + 16B
4. 64B
There's an error in line 3 :/....

Secure shared web hosting using MAC Framework
Hi all,
I am looking at securing a web server using the FreeBSD MAC Framework.
To make things clear I will call the hosted users "web users". Those are the issues I am dealing with:
** Network Security **
- Web users shouldn't be able to connect to reserved local ports apart from 25(smtp); 80(http); 443(https) and 3306(MySQL)
Solution:
run the web server and web users shell in
