changing rights in /proc/sys
how can I chmod /proc/sys/net/ipv4/ip_forward such that nobody but root can see what value it has ?
I tried chmod 640 /proc/sys/net/ipv4/ip_forward but when I do a ls /proc/sys/net/ipv4/ip_forward the rights remain the same.
can this be done some other way ?

Maybe applying the grsecurity patch and then chosing the restrict permissions on /proc might work for you.

I am using Debian Stable and it seems that there is no valid grsecurity patch in the stable portage for kernel 2.4.27. Could you provide a link where can I find a grsecurity patch for kernel 2.427, googleing around didn't help ...

AFAIK the only distro on earth that deserves major credits for having a GRSecurity kernel on tap is Gentoo. For all others you'll have to roll your own.
