Dear all
help me please,
I want execute this command by php: "service network restart" or "reboot". owner and group of this php file is root. and I execute this command "chmod +s test.php" but I can't execute this command.
what can I do it ?

It may not be in your command path. Type in the entire path. For me to restart my network for example, I have to type in

Code:

/etc/init.d/net.eth0 restart

If you cd to the directory /etc/init.d or whereever your command is, and put a ./ in frount of it as well. Like this:

Code:

cd /etc/init.d
./net.eth0 restart

They both work the same way and will do the same thing.

Hope that helps.

I execute it in this way, but didn't right.
I can't execute supper command such as "reboot" & "service ... restart " but I can do "ls" & "ifconfig" & "ping" and saw reply from this.
why?

Are you logged in as root? This is not like windoze where when you are in, you are in. Each user has his/her own privledges. If you are not sure who you are logged in as, type in whoami. That will tell you who you are logged in as. If it is other than root, then it won't work if that command requires root access.

If it says you are not root, type in su, hit return, then type in your root password. Then try again.

Let me know what happens.

coution I want do this in php.
what is you Solution?
I want read & write 2 some file and then restart some service or restart computer. what is the best way?

dalek · 09-24-2004, 03:38 AM

The best way is to make sure you are logged in as root and not as a user. What does whoami say?

yazdan · 09-24-2004, 09:01 AM

I set on httpd.conf user=apache group=root
and then reply apache when I entered whoami.

Me lost. I'm not sure what you are doing really.

Going by your name and such, I suspect english may not be your native language. You may want to check out the link in my sig. May get a better response there.

Dear dalek,

I want to create a php page for DHCP .
therefore I should :
read from /etc/dhcpd.conf and write to /etc/dhcpd.conf.
restart the service.
now I can do read & write. but I can't restart this service in this way "service dhcpd restart".

what is you Solution?

you might consider using a sudo command rather than making apache run as root, it would probally be a little more secure

yazdan · 09-25-2004, 01:41 AM

Dear Kahless,
May you help me about format of sudo command.
How can I execute "service dhcpd restart" or "reboot" by sudo?

May I neet to reconfig /etc/passwd or /etc/sudoers files?

yazdan · 09-26-2004, 11:27 PM

you should confirm that there is no body hear can help me.

dalek · 09-27-2004, 05:37 AM

I think nobody here can figure out what you are doing. I haven't yet.

You know what you are trying to do. We do not until you tell us. If we don't know what you are trying to do, we can't help.

Help us to understand what you are doing, then we can help you do it.

Later
