Security on shared memory & semaphores

[rzs0502]

Hi,

I've been trying to find out how to change the MODE on IPC's on AIX.
eg.
ipcs -s
IPC status from /dev/mem as of Fri Jan 14 13:43:16 USAST 2005
T ID KEY MODE OWNER GROUP
Shared Memory:
m 0 0x0d001675 --rw-rw-rw- root system
m 1 0xe4663d62 --rw-rw-rw- imnadm imnadm
m 2 0x9308e451 --rw-rw-rw- imnadm imnadm
m 3 0x52e74b4f --rw-rw-rw- imnadm imnadm

I want to remove the world rw on these.

Thanks!
