2. Linux does not support suid scripts.
Yes it does, but you have to consider the filesystem it is in though. Many installations only allow SUID scripts in OS filesystems (/, /bin, /sbin, /usr/bin depending how you have them mounted) and as such you may find that /home (or wherever) is mounted with that disabled.
Change to the directory where the script is and do the following:-
Remember to escape the forward slash in the grep command, e.g.
What do you have in the fourth column? Actually, post the whole line.
I am researching ways in which to backup files or whole file systems for backup to another system.
We are using Suse Linux 7.0 with no tape backup devices or secondary disks.
What utilities would be the best to use for a simple yet flexible script for backup purposes?
tar, cpio, compress. (3 Replies)

Just learning about the privilege escalation method provided by setuid. Correct me if I am wrong but what it does is change the uid of the current process to whatever uid I set. Right ?
So what stops me from writing my own C program and calling setuid(0) within it and gaining root privileges ?

umount
UMOUNT(8) BSD System Manager's Manual UMOUNT(8)NAME
umount -- unmount filesystems
SYNOPSIS
umount [-fv] special | node
umount -a | -A [-fv] [-h host] [-t type]
DESCRIPTION
The umount command calls the unmount(2) system call to remove a special device or the remote node (rhost:path) from the filesystem tree at
the point node. If either special or node are not provided, the appropriate information is taken from the fstab(5) file.
The options are as follows:
-a All the filesystems described in fstab(5) are unmounted.
-A All the currently mounted filesystems except the root are unmounted.
-f The filesystem is forcibly unmounted. Active special devices continue to work, but all other files return errors if further accesses
are attempted. The root filesystem cannot be forcibly unmounted.
-h host
Only filesystems mounted from the specified host will be unmounted. This option is implies the -A option and, unless otherwise spec-
ified with the -t option, will only unmount NFS filesystems.
-t type
Is used to indicate the actions should only be taken on filesystems of the specified type. More than one type may be specified in a
comma separated list. The list of filesystem types can be prefixed with ``no'' to specify the filesystem types for which action
should not be taken. For example, the umount command:
umount -a -t nfs,hfs
umounts all filesystems of the type NFS and HFS.
-v Verbose, additional information is printed out as each filesystem is unmounted.

/etc/fstab filesystem table
