Ordinary users should never be able to write /usr/bin, etc. Also, the root filesystem - var, etc, usr, opt and friends - should all be on a filesystem unto itself with no application data at all. Therefore /var/spool, /var/tmp, and so on belong on another physical filesystem.
Consider -
in /etc/profile.
For ksh and sh (Bourne) on HP-UX; for batch systems. Interactive users can unset the
soft limit. But -- they should not have write access to the root filesystem

Hi ,
Working on AIX 4.3. An internal error from my apps engine suddenly causes the engine to die. During this time i do notice a core file being dumped in the directory from where I try to re-start my engine.
Q is how does one read this core file, or I should say 'what is this core file'?
thnx (2 Replies)

Hi Guys,
I was wondering if somebody could give me a link to a very good source of information or document about core dump process and How to's about it. I have also googled it and found some articles myself.
Thanks

Hi guys,
just want to know which core file pattern is best to set for core dumps:
1) per-process file name pattern
or
2) global file name pattern.
I will really appreciate an explanation why the chosen one is better.
Thanks a lot guys. (2 Replies)

copyfs-mount
COPYFS-MOUNT(1) User Commands COPYFS-MOUNT(1)NAME
copyfs-mount - mounts a versioned file system
SYNOPSIS
copyfs-mount version-directory mount-point
DESCRIPTION
This script lets you mount a CopyFS file system. version-directory is the directory where the files and version information will be stored
by CopyFS.
When using CopyFS for the first time, copyfs-mount will create the required files in the version-directory before running copyfs-daemon.
mount-point is the directory where the copyfs file system will be mounted. This is where the users will have access to the files.
If you want to mount a CopyFS at '/mnt/fs', whose version directory is at /var/versions, you would use:
root@host# copyfs-mount /var/versions /mnt/fs
To unmount it, simply do:
root@host# umount /mnt/fs
As you would do for any other filesystem.
You can also allow an ordinary non-root users to mount and unmount CopyFS filesystems provided that the user is added to the 'fuse' group.
Ordinary users will be able unmount the filesystem, using the fusermount command:
$ fusermount -u mount-point
