Solaris

This is Solaris 10, by the way.

I am aware of ACLs or something like that in Solaris 10 where you can change who can access directories and such that goes beyond the standard permisisons (chmod and rwxrwxrwx).

Although I thought when these were being used, the permissions listing would show a '+' appeneded to the permisions, like shown below:

Code:

# ls -laFd local
dr-xr-xr-x+   1 root     root           1 Nov 13 13:27 local/

However, in this case there is no '+'. It looks like this:

Code:

# ls -laFd local
dr-xr-xr-x   1 root     root           1 Nov 13 13:27 local/

Yet even as root I cannot modify it:

Code:

# chmod +w local/
chmod: WARNING: can't change local/

This is /usr/local by the way. And it's not mounted read-only...

Code:

# mount|grep -i usr

Code:

# grep -i usr /etc/vfstab
#/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr          ufs     1       yes     -

Code:

# mount|grep -i local

Code:

# grep -i local /etc/vfstab

And just to make sure:

Code:

# id
uid=0(root) gid=1(other)

Code:

# uname -a
SunOS dncs 5.10 SunOS_Development sun4u sparc SUNW,Sun-Fire-880

How can I modify the permissions on that directory?

I noticed that the permissions are : root:root, whereas you are root:other ? is it possible that the group you are in doesn't have rights to modify certain files / folders ?

No. It's got something to do with extended permissions, I think.

What are your rights on the parent directory of local?

What does this command show:
ppriv -e -D chmod +w local/

# ls -laFd /usr
drwxr-xr-x 33 root sys 1024 Nov 14 05:34 /usr/

# ppriv -e -D chmod +w local/
chmod: WARNING: can't change local/
# pwd
/usr
