I got another problem with RedHat 9. The sudo doesn't work any more with root. It hangs. But it still works with other users.
Realizing, up front, that this doesn't answer your question, I do have ask...why would you bother using sudo as root? The whole point of sudo is to be able to run commands as root...if you're already root, why would you need to use sudo?
You stated above that sudo hangs when running as root. Now you're saying that it hangs when run as nobody (or whatever your php script is running as). Please describe exactly what the problem is you're having so that we can have some sort of clue as to how to help you.
Do the symptoms change if you run the script interactively instead of
from a web browser?
My php script exec("sudo /usr/local/bin/setpassword $uid $pass"); hangs,
so I did #ps -ef |egrep 'nobody|sudo' and I get these:nobody 13526 13523 0 Apr15 ? 00:00:00 /usr/local/apache/bin/httpd -DSSL
nobody 13527 13523 0 Apr15 ? 00:00:00 /usr/local/apache/bin/httpd -DSSL
nobody 13528 13523 0 Apr15 ? 00:00:00 /usr/local/apache/bin/httpd -DSSL
nobody 13636 13523 0 Apr15 ? 00:00:00 /usr/local/apache/bin/httpd -DSSL
root 13914 13526 0 Apr15 ? 00:00:00 sudo /usr/local/samba/bin/setpassword.exp aaa asdasd
I dont't know why the last line above is running as root. It should be nobody. Because apache is running as nobody.
The sudoer file has a line like nobody ALL= (ALL) NOPASSWD: ALL
and another line like root ALL= (ALL) ALL
So when I login as root and test sudo command, it hangs. Everything was fine before.
Also when I login as root and run command: strace sudo ls, it hangs at the last line below:
