ulimit and /etc/security/limits file permission
Hi there,
I am working on AIX and i dont have permission for /etc/security/limits file.
In the man page of ulimit it is mentioned that it will get the limitations for me from /etc/security/limits file.
the file permission for ulimit command is
-r-xr-xr-x 15 bin bin 1453 Sep 6 15:02 /usr/bin/ulimit
It doesnt have sbit set and i dont have any permission on /etc/security/limits file. So how did ulimit command returned the results for me?
Thank you...

nofiles(descriptors) 1024
This means that I can open up to 1024 file per process? But wonder if there is any hardlimit imposed by Solaris 2.6 (eg 255) ?
By the way, is there any tool that can trace which files (or sockets) are opened by a process?
Thanks

initscript
INITSCRIPT(5) Linux System Administrator's Manual INITSCRIPT(5)
NAME
initscript - script that executes inittab commands.
SYNOPSIS
/bin/sh /etc/initscript id runlevels action process
DESCRIPTION
When the shell script /etc/initscript is present, init will use it to execute the commands from inittab. This script can be used to set
things like ulimit and umask default values for every process.
EXAMPLES
This is a sample initscript, which might be installed on your system as /etc/initscript.sample.
#
# initscript Executed by init(8) for every program it
# wants to spawn like this:
#
# /bin/sh /etc/initscript <id> <level> <action> <process>
#
# Set umask to safe level, and enable core dumps.
umask 022
ulimit -c 2097151
PATH=/bin:/sbin:/usr/bin:/usr/sbin
export PATH
# Increase the hard filedescriptor limit for all processes
# to 8192. The soft limit is still 1024, but any unpriviliged
# process can increase it's soft limit up to the hardlimit
# with "ulimit -Sn xxx" (needs a 2.2.13 or later Linux kernel).
ulimit -Hn 8192
# Execute the program.
eval exec "$4"
FILES
/etc/inittab, /etc/initscript.
