Hello!
As I can't post in "Networking & Security" [don't ask why.. I don't know], I'm posting here, as grsec and pax touch kernel things too ^^.

I'd like to configure two laptops for firewalling and users application :

laptop 1 : firewalling
Problems : I'd like to set up some security as it's for firewalling purpose, such as overflow limits and so on. But... well.. i'm a nob for those things. I've changed profile to hardened, installed hardened-sources [stables], installed paxctl, gradm... yeah, fine. but I don't absolutely know how to set it up. I found some doc here : http://www.gentoo.org/proj/en/hardened/grsecurity.xml but seems chpax is deprecated [and it doesn't have any initscript as written in this doc].
-> Question : can someone give me either howto, or examples ?

laptop2 : users application
I'd like to authorize only screen, scp and irssi on this laptop. I set up profile hardened, with hardened-soruces [stable]... but in fact, how can I limit users' access to programmes ? How can I prevent usres to go anywhere in my tree? I'd like to block them in their home.. or something like that.
-> Question : can someone give me either howto or examples ?

Thanks in advance!

And sorry for posting in this part, but as I said... I just can't post in the good one.. So if a moderator could send this one in Networking & Security, and check why I can't post in this part... thanks ;)

See you !

You'd check if you've some messages in your box (like if you're accidentally banned from Netw.&Sec.) or send message to moderator.

And here are few links to documentation.

Hello!
thanks for second links, as first one was already known [and it's outdated in fact, as chpax isn't used anymore on recent gentoo systems...]

I'll send a message to moderators for my problem. I don't thing I'm already banned from this forum, as it's my first time posting on it :->. But it's not really the purpose of my post ;)

If you have some other links... please share them :)

See you!
