I am recently learning about linux (Cent OS) and i came across to a weird problem. I am going through a chapter "Managing Services" and in the book its written to restart a network i should use the below command

/etc/init.d/network restart

But when i am using the above command nothing is happening. Instead when i use this command "/etc/init.d/service network restart", i am able to restart. Could anyone explain what is the difference ????

ls -la /etc/init.d/network what is the output ? in CentOS you should be able to call any service using service service_name command (you don't actually need the /etc/init.d/) service is merelly an agent that will simplify your services commands. Also are you using a remote user to get to root or physical access ? if you are using a user make sure you are moving to root with the follow command su - or su - root – Prix Aug 25 '10 at 18:57
@Prix - using sudo i the better way to go instead of escalating to a full root shell. – Zypher Aug 25 '10 at 19:27
The output of ls -la /etc/init.d/network is -rwxr-xr-x 1 root root 8257 Jul 4 2009 /etc/init.d/network and yes i did tried sudo but nothing is happening. – user52337 Aug 26 '10 at 8:11

You're probably not root when you're running /etc/init.d/network restart. It should work the same as service network restart (note that service is not prefixed with /etc/init.d).

I am the root user... – user52337 Aug 26 '10 at 8:15
Do you see anything in /var/log/messages after you run the command? That's very strange that you see no output whatsoever. – vmfarms Aug 26 '10 at 13:38
