umask not working

libin88 · 08-23-2007, 01:52 PM

My umask setting is 0077, see below

[root@server ~]# umask
0077

the permission of the new file suppose to be
-rw-------

but what I got is
-rw-rw-rw-

No matter how I change the umask setting (0000, 0011, 0700 etc.), the file permission I got is always -rw-rw-rw-.

Do you know what is wrong with my umask, and how to fix it?

Thank you very much!

Hi.

That's a bit odd. What type of filesystem are you doing this on? Is it FAT32 by any chance?

If not, try:

Code:

pwd
umask
touch wibble
ls -l wibble

and post the output.

Well it seems to work for me...

Try to remove the file first (it may retain the permissions it had when it was created)

My file system is Linux EXT3.

[root@server ~]# pwd
/root

[root@server ~]# umask
0022

[root@server ~]# touch wibble
[root@server ~]# ls -l wibble
-rw-rw-rw- 1 root root 0 Aug 23 15:54 wibble

I am completely stumped. Anyone else?

lakris · 08-23-2007, 03:17 PM

did you try to remove the file (or touch a new one) ?

Yes, I DID.

I'm not sure if this is possible but does the directory have any sticky bits set?

Not sure what is sticky bits set. How to check that?

Based on above, your umask is 0022, not 0077 as you told us.
Please, check.

It doesn't matter, no matter my umask is, my file permission is always
-rw-rw-rw-

I don't remember exactly but do You have a t in there instead of x (for group or all)?
The directory isn't by any chance controlled by samba?
What is your shell?

I think this is intriguing!

NO, there is no t for both group and all. My machine is not using samba either. I am using bash shell.

Is there way I can re-install umask? I am using FC6.

lakris · 08-23-2007, 04:33 PM

Can You do the following commands:

Quote:

lakris@ubuntu:~$ umask -p
umask 0022
lakris@ubuntu:~$ umask -S
u=rwx,g=rx,o=rx
lakris@ubuntu:~$ umask 0077
lakris@ubuntu:~$ umask -p
umask 0077
lakris@ubuntu:~$ umask -S
u=rwx,g=,o=
lakris@ubuntu:~$

What is Your output?
and what does Your /etc/profile say?
