Are the /var/www/vhosts/<domain name>/cgi-bin/test files on the / file system as appears from /proc/mounts? (post 4)
Can you change the holding directory's owner to root? (post 8)
What has changed between the first and fourth posts? Usually when the owner is just a UID, not an actual username, it means you're working on a network filesystem (NFS, etc), which means root won't have the same permissions as on the local filesystem. (post 13)

Thanks

Try to see what is accessing it & kill the process

Code:

fuser -ifk test

Raakh5 · 03-22-2012, 05:15 AM

[root@myServer cgi-bin]# fuser -ifk test
[root@myServer cgi-bin]#

Nothing happened by running this command. thanks for your reply

pan64 · 03-22-2012, 07:20 AM

can you look at /var/log for error messages related to that directory?

Raakh5 · 03-22-2012, 08:06 AM

I check /var/log/messages but nothing about cgi-bin/test or test or cgi-bin

thanks

ls -l ../cgi-bin

Raakh5 · 03-22-2012, 12:58 PM

[root@myServer cgi-bin]# ls -l ../cgi-bin
total 4
drwxrwxrwx 2 medical5 psacln 4096 Mar 21 01:13 test
[root@myServer cgi-bin]#

I am sorry Raakh5 I meant ls -l ../ so that we could see the permissions on cgi-bin.

Raakh5 · 03-22-2012, 01:53 PM

[root@myServer cgi-bin]# ls -l ../
total 4
drwxr-x--- 3 10041 psaserv 4096 May 2 2010 cgi-bin
[root@myServer cgi-bin]#

There is point to be noted that in this post catkin was drawing my attention in post with time stamp "Yesterday 10:26 PM catkin"
drwxrwxrwx 2 medical5 psacln 4096 Mar 21 01:13 test

Now with your stated command its showing two users. Why there are two users whereas I never given any privileges to medical5?

Thanks again

suicidaleggroll · 03-22-2012, 02:04 PM

medical5 is the user, psacln is the group

Raakh5 · 03-22-2012, 02:46 PM

What I did now is as follow:
[root@globalsteelweb cgi-bin]# ls -l ../cgi-bin
total 4
drwxrwxrwx 2 10013 psacln 4096 Mar 21 01:13 test
[root@globalsteelweb cgi-bin]# chown root test
[root@globalsteelweb cgi-bin]# ls -l ../cgi-bin
total 4
drwxrwxrwx 2 root psacln 4096 Mar 21 01:13 test
[root@globalsteelweb cgi-bin]# rm -rf test
rm: cannot remove directory `test': Permission denied
[root@globalsteelweb cgi-bin]# chgrp root test
[root@globalsteelweb cgi-bin]# ls -l ../cgi-bin
total 4
drwxrwxrwx 2 root root 4096 Mar 21 01:13 test
[root@globalsteelweb cgi-bin]# rm -rf test
rm: cannot remove directory `test': Permission denied
[root@globalsteelweb cgi-bin]#

thanks

This is very puzzling. To sum up the investigation so far:

rm -fr test results in "permission denied".
There are no ACLs on test.
The test directory is on a local writeable file system.
test's parent directory is not writeable by root.

I just tested a similar setup and was able to remove the test directory even without using rm's -f option:

Code:

c@CW8:~$ mkdir -p /tmp/cgi-bin/test
c@CW8:~$ chmod 750 /tmp/cgi-bin/
root@CW8:~# rm -r /tmp/cgi-bin/test/
[no output, directory test was removed]

Are there any files in the test directory? Can you create and delete files? What happens if you try to change ownernship of test's parent directory to root? Here are commands to test that, assuming cgi-bin is your current directory:
/bin/ls -l test
touch testfile test/testfile
rm testfile test/testfile
chown . root
touch testfile
rm testfile
rm -fr test

Thanks for helping me continuously
