Solaris 9: group won't be listed

xpucto · 02-08-2006, 10:26 AM

I have 2 solaris: 9 and 10.
I noticed that in Solaris 9, you get get the owner's group when you do ls -l. Is is possible to have it appear?
To be clear, under solaris 9, I have:

Code:

drwxr-s---  10 bob      512 Apr 30  2000 Projects

under Solaris 10, I have:

Code:

drwxr-s---  10 bob http         512 Apr 30  2000 Projects

My Problem is that I just did a rsync between the 2 solaris. This directory "Projects" is on apache. When I try to read the files in the directory Projects (that has setuid permissions as you can see) from internet, I get the message "You don't have permission to access /Projects/ on this server." But the same files are readable on the first server.

So I guess that the problem has to do with the group-ID.

Thanks for any help.

Hopefully, "ls -l" behaves the same whatever Solaris version you are running.

Can you double check, and run on both platforms:

Code:

uname -a
/bin/ls -l /etc/hosts
/bin/ls -ln /etc/hosts

/bin/ls -ln /etc/hosts

on solaris 9, I have

Code:

[sunsite@root:/servers/http/docs]# /bin/ls -l /etc/hosts
lrwxrwxrwx   1 root     root          12 Feb 13  2003 /etc/hosts -> ./inet/hosts
[sunsite@root:/servers/http/docs]# /bin/ls -ln /etc/hosts
lrwxrwxrwx   1 0        0             12 Feb 13  2003 /etc/hosts -> ./inet/hosts
[sunsite@root:/servers/http/docs]# uname -a
SunOS sun1 5.9 Generic_112233-04 sun4u sparc SUNW,Ultra-Enterprise

on solaris 10:

Code:

# /bin/ls -l /etc/hosts
-rw-r--r--   1 root     root          87 Jan 27 14:15 /etc/hosts
# /bin/ls -ln /etc/hosts
-rw-r--r--   1 0        0             87 Jan 27 14:15 /etc/hosts
# uname -a
SunOS sun2 5.10 Generic sun4u sparc SUNW,Sun-Fire-V240

I see big differences in hosts... but can't interpret them...

Two comments:
- The group problem your were complaining of doesn't show up.
- Your Solaris 10 installation is broken. /etc/hosts has to be a symbolic link.

But the fact is: doing ls -l shows me only owner without the group (ok, except for the hosts file). Is it normal in solaris 9, or do I have a problem?

How come?! I just started with this server and almost did nothing with it. How may I correct this, and how may I understand how this could happened?

Thanks for your help.

You have a problem.
What shows "ls -ln" on the very same file ?
It could be you have a group whose name is space i.e. " " ...

Well you or someone else removed /etc/hosts, then create it again as a plain file, not a casual behaviour.

Perhaps by searching who was logged in on Jan 27 at 14:15 ...

Thanks for your quick reply!
On Solaris 9, ls -ln:

Code:

drwxr-s---  10 bob      512 Apr 30  2000 Projects

so it shows the same thing as with ln -l! UID and GUI are not shown.

on solaris 10 the ls -ln gives:

Code:

drwxr-s---  10 102      100          512 Apr 30  2000 Projects

102 is Bob, and 100 exists in /etc/group as http.

What do you think about all this?!

Thanks again for your assistance.

try, on S9:

Quote:

type ls
/bin/ls -ln

xpucto · 02-09-2006, 03:00 AM

Excellent! Thanks for your help, I can see a bit more clearly:

Code:

 type ls
ls is hashed (/usr/ucb/ls)

on Solaris 10, I get

Code:

type ls
ls is hashed (/usr/bin/ls)

Is it the explanation?
when I do

Quote:

/usr/bin/ls -l

or

Quote:

/bin/ls -l

then I get

Quote:

drwxr-s--- 10 bob http 512 Apr 30 2000 Projects

Great! I guess I just have to change the alias of ls?

So the rsync respected the permissions and the group http is actually correct. I guess the question why the setgid doesn't work belongs to another forum.

I really thank you for your help.

It's not an alias problem, but a PATH one.

My advice would be to remove the /usr/ucb from the PATH, or at least to put it at the end of it, not before /usr/bin.

Thanks a lot!
