Hey everyone!

Our class was assigned an exit questionnaire about all the things we’ve learned throughout the course of our program (Associates of Science: Computer Networking Systems). We’ve got all but 1 question not answered..and frankly it’s because none of us are big linux buffs >.>

Here’s the question:

A fedora server is storing security logs that contain a vast array of data. Design a tool chain that would contact an administrator via email in specific risk scenarios, and wold otherwise provide daily updates.

I’m not the type to ask for answers, but if someone could merely point me in the right direction, I’d be more than grateful ^_^

Thanks in advance!

Hi,
I’m using SDE-GCC to compile programs that runs on “bare iron” (i.e. no operating system). I would like to be able to create programs (“executables”) that can be loaded to arbitrary addresses on RAM and run from there.

I used to compile and run successfully such kind of programs on ARM processor (with different tool-chain of course) where the program was PC relative. MIPS don’t expose the PC and seems it has its own way to
do it.

I tried to use -mabicalls -fPIC compilation flags to create PIC (Position Independent Code): when I examined the “objdump” I could find that the “GOT” (global offset table) is still made of absolute
addresses so the program is bounded to run on a specific address (the linking address).

Can you direct me on how to do that?

Thanks in advance,

Eli

A system would be a collection of subsystem, really a collection of tools.
There would need to be a tool chain installation. If the tool chain is not installed , why would it work ? Is “systems integration” invariably a “clayton’s” system integration for the supplier’s benefit, the supplier then being able to claim payment for completed work.

If genuine tool chain installation was being done why wouldn’t the supplier be able to claim payment for tool chain installation ?

Is tool chain installation typically sabotaged by a rogue section of the supplier organisation – the rogue section then involving themselves as messiahs who assist with systems integration ?
