[Haifux] slides for monday's 'kernel, modules, drivers' lecture

2004-01-17 Thread guy keren 

the slides are temporarily available at:

http://users.actcom.co.il/~choo/kernel-modules-drivers/

These slides do NOT cover kernel compilation procedures - these will be
covered by a seperate lecture, in 2 weeks from now.

the current lecture deals with the notions and basic ideas one needs in
order to be prepared for the grand kernel compilation task ;)

the downloadable tar.gz file is at

http://users.actcom.co.il/~choo/kernel-modules-drivers.tar.gz

hopefully, someone would install it on haifux's web site soon.
(by the way, if it's more convinient that i e-mail the tar.z file to
 someone, please let me know, for the next time to come.)

thanks,

device drivers in _which_ kernel, exactly? 2.4 or 2.6? is there a
difference, at all, in the basic API?

i prefer the kernel 2.6 overview, actually.

2.6. I don't play with 2.4 anymore if I have a choice. 

Yes, there are quite a lot of differences, but they are spread over a
lot of functionality, so you are unlikely to meet all of them in a
given driver. See lwn.net's driver porting series
(http://lwn.net/Articles/driver-porting/) for details. My talk is more
of an introduction to the basic concepts of writing "software" device
drives for Linux, and thus while the code is based on 2.6, it should
be fairly easily portable to 2.4.

Noted. I think that's 2 for Drivers, 1 for kernel 2.6 so far. I don't
mind either way. 

Cheers,

guy, and every other propect lecturer:
supplying a URL from which the whole slides show can be downloaded is a
great way to transfer them.

Thanks to wget!

slide 1 

- the capitalization of Kernel, Driver and Hardware is a bit
jarring. Same thing for all other slides. 

slide 2

- the kernel can be compiled entirely monolithic (no modules)

slide 8

- mention what 'c' and 'b' stand for

- explain why we have major and minors?

slide 10

- mention that for the user, the distrinction between character and
block devices is irrelevant? it's only the driver that cares
(different kernel APIs)

slide 11

- 2.6 disables module unloading (by default?) 

slide 13

- mention /lib/modules/`uname -r`/build?

slide 16

- mention that module options can also be passed on the
insmod/modprobe command line?

- mention how to find which modules options a driver supports?
(modinfo, source)

Overall, excellent talk! see you on Monday. 

Cheers,

[Haifux] A suggestion for a lecture - How to protect your network, using IPtables.

2004-01-17 Thread Adir Abraham 
Hi all,

I wish to give a lecture regarding IPtables(netfilter, if to be exact).
Since until now, there were only two specific lectures regarding IPtables
(mainly about NAT), I wish to give a lecture for a wider audience - the
concepts of IPtables, how to use it (properly), some examples, and alike. I
also wish to show some ways to protect your home/office network using IPtables,
against attacks such as denial of service, some floods, etc. I will also
talk about building internet firewalls based on stateless and stateful
packet filtering, if there's enough time left.

If the lecture (while I plan it), becomes larger than what I expect, I
might wish to split it to two lectures. The first lecture will deal with
working with IPtables, and many examples, and the 2nd one will talk more
about the common attacks and the ways to use IPtables in order to protect
against them, in addition to building a firewall for the specific problem.

Let me know if you wish to hear such a lecture, and if you do - would you
prefer one lecture (that won't get too deep into the subject, but will
show concepts and examples), or two lectures, as mentioned above.

Best regards.
