sudo selectively execute file, * wildcard on dir set with "(ALL) NOPASSWD:".

[Kent Ho]

Hi All,

I'm experiencing a problem with sudo.

sudo selectively execute file in a directory, * wildcard on dir set with "(ALL)
NOPASSWD:".

I created a script called "script1.sh" in a directory.   When I execute this
script with sudo, it ask me for password which not suppose to happen.  I break
out with ctrl+c.

I then copy script1.sh to a new file in the same directory as "script2.sh".
Now I execute "script1.sh" again with sudo, now it will execute.

There is no change on script1.sh, All I done is created a new file in the
directory.  But now sudo do not ask me password any more.

At this point I can execute both scripts with sudo with no password.  Which is
normal.

Now I delete "script2.sh".  Now the directory has only 1 file again
"script1.sh".  I execute script1.sh now it will ask me for password again.

All executable file should be executable regardless, I don't know why this is
happening.  Number of files in directory affects sudo?


Version-Release number of selected component (if applicable):
[mdrop@c-in3sf--02-04 bin]$ rpm -qa | grep sudo
sudo-1.6.9p17-5.el5

How reproducible:
Everytime.

Steps to Reproduce:
Here is the command sequence from the terminal:
===============================================
[mdrop@c-in3sf--02-04 bin]$ pwd
/usr/local/site/operations/dsh/bin
[mdrop@c-in3sf--02-04 bin]$ sudo -l | grep dsh
    (ALL) NOPASSWD: /usr/local/site/mailscripts/spf/bin/*,
/usr/local/site/mailscripts/ws/bin/*, /usr/local/site/operations/dsh/bin/*,
/usr/local/site/operations/bin/*
[mdrop@c-in3sf--02-04 bin]$ ls -l
total 0
[mdrop@c-in3sf--02-04 bin]$ echo "echo test123"> script1.sh ; chmod +x
script1.sh
[mdrop@c-in3sf--02-04 bin]$ ls -l
total 4
-rwx------ 1 mdrop mdrop 13 Dec 30 07:04 script1.sh
[mdrop@c-in3sf--02-04 bin]$ sudo /usr/local/site/operations/dsh/bin/script1.sh 
Password: 
[mdrop@c-in3sf--02-04 bin]$ cp script1.sh script2.sh 
[mdrop@c-in3sf--02-04 bin]$ ls -l
total 8
-rwx------ 1 mdrop mdrop 13 Dec 30 07:04 script1.sh
-rwx------ 1 mdrop mdrop 13 Dec 30 07:04 script2.sh
[mdrop@c-in3sf--02-04 bin]$ sudo /usr/local/site/operations/dsh/bin/script1.sh 
test123
[mdrop@c-in3sf--02-04 bin]$ sudo /usr/local/site/operations/dsh/bin/script2.sh 
test123
[mdrop@c-in3sf--02-04 bin]$ rm script2.sh 
[mdrop@c-in3sf--02-04 bin]$ ls -l
total 4
-rwx------ 1 mdrop mdrop 13 Dec 30 07:04 script1.sh
[mdrop@c-in3sf--02-04 bin]$ sudo /usr/local/site/operations/dsh/bin/script1.sh 
Password: 
[mdrop@c-in3sf--02-04 bin]$ 
============================================================

Actual results:
$ sudo /usr/local/site/operations/dsh/bin/script1.sh 
Password: 

Expected results:
$ sudo /usr/local/site/operations/dsh/bin/script1.sh 
test123

What could have caused this?

Any help is highly appreciated.

Thanks.

Garlum.

Read the docs.

From the sudo man page:

-k          The -k (kill) option to sudo invalidates the user's timestamp
by setting the time on it to the Epoch.  The next time sudo is run a
password will be required.  This option does not require a password and
was added to allow a user to revoke sudo permissions from a .logout file.

-A

Removing * after / fixed the problem.

Thanks Dany.
