chmod u+s not working good?

[uadm26]

Hi,

When i try to cahnge a file permissions, setting the setid (+s) by root that's what append, appears the letter "S", not the "s", in lower case. Why?

root@beta5:/tmp/testes# chmod u+s tt
root@beta5:/tmp/testes# ll
total 2
-rwSr--r-- 1 root sys 54 Sep 6 14:26 tt
root@beta5:/tmp/testes#

The file needs to have the execute (x) bit set before you set the set-uid bit. Try this instead:

# chmod 4744 tt

[RAC_1]

chmod 4766 file_name

There's no execute permission set.

Hi Joel:

The capital letter "S" means that the execute bit isn't set for the owner but the setuid bit is. Do:

chmod 4544 to your file to see a change from the capital "S" to a lowercase "s".

Two suggestions:

1) Make sure there is no process with a filehandle on that file. I got those results when a daemon had a constant hold on a file. The daemon was unfortuneately owned by root.

2) Perhaps try the chmod command numeric instead of by letters. chmod 7xxx or 5xxx the letters in my example are the normal file permissions.

I got the same results as you on a Linux machine(my HP-9000 is shut for noise reasons).

Chmod 7555 worked and produced possibly desireable results.
