Chown Issues - Stumped

Peter_17 — Fri, 27 Jul 2001 19:10:02 GMT

All,

I'm in a NIS/NFS environment where I can log into either HP's or Suns. In the HP environment, chown works, but in the Sun environment, it doesn't. Please see details below:

[myname@SUNmachine1]% ls -l
-rwxr-xr-x 1 myname sysadmin 1586 Jun 22 16:11 file3
-rwxr-xr-x 1 myname sysadmin 9 Jul 9 09:48 test.sh
[myname@SUNmachine1]% id
uid=12345(myname) gid=14(sysadmin)
[myname@SUNmachine1]% chown yourname test.sh
chown: test.sh: Not owner
[myname@SUNmachine1]%
[myname@SUNmachine1]% telnet HPmachine1

[myname@HPmachine1]% ls -l
-rwxr-xr-x 1 myname sysadmin 1586 Jun 22 16:11 file3
-rwxr-xr-x 1 myname sysadmin 9 Jul 9 09:48 test.sh
[myname@HPmachine]% chown yourname test.sh
[myname@HPmachine]% ls -l
-rwxr-xr-x 1 myname sysadmin 1586 Jun 22 16:11 file3
-rwxr-xr-x 1 yourname sysadmin 9 Jul 9 09:48 test.sh
[myname@HPmachine]%

Anyone have any suggestions as to why this is?

Any and all help appreciated!!

Pete

hummmmmm???

For some reason, the system does not think you are myname?

Try to touch a file in that dir.

touch test1.sh

Is the owner myname or is it another?

...jcd...

Yes, not a problem... I can create it, but after that, I cannot chown OR chrgp it...

Has someone somehow changed permissions on chown on the Sun boxes? On you sun box do an 'll `which chown`' and see what the permissions look like. I'm not logged into the office so I can't check on one of our sun boxes.

Hi,
This is a security feature provided by SUN ... the obvious reason is that "no unpriviledged user should be able to give or take ownership".
Hope this clarifies the query.

yes,suhas is right!

on Sun(solaris) , when you "man chown" , it prompts this to you !

-=
The operating system has a configuration option
{_POSIX_CHOWN_RESTRICTED}, to restrict ownership changes.
When this option is in effect the owner of the file is
prevented from changing the owner ID of the file. Only the
super-user can arbitrarily change owner IDs whether or not
this option is in effect. To set this configuration option,
include the following line in /etc/system:

set rstchown = 1

To disable this option, include the following line in
/etc/system:

set rstchown = 0

{_POSIX_CHOWN_RESTRICTED} is enabled by default. See sys-
tem(4) and fpathconf(2).

Hi,

Just for info: on HP-UX you can restrict the chown command with "setprivgrp", see man 1m setprivgrp.
