Hi,

I dont know perhaps I am the paranoid penguin type.
but I believe there are exploits available for the 2.4 kernel at least 
up to 2.4.26 local exploits or DOS.

Sincerly,
Aaron Waller


P.S. has Aurora Linux Continued to develop ?
The links I have found made it look like a dead distro much like 
redhat-6.2. If so any information on it would be wonderfull.

Thanks again,
Aaron Waller
