ethtool : command not found

Hi,
I am uising Suse linux on my system and i tried :
man ethtool and i got the manual for ethtool but when i tried to use the command as:
ethtool -a eth0
it says Command not found.
also, i tried rpm -qa|grep ethtool i got:
ethtool-3-15.2 so,it means my system has ethtool server or package installed then why i am unable to use this command and getting output as: command not found

rpm -ql ethtool will tell you that it's installed in /usr/sbin, which is not in the PATH for normal users. Run it using the absolute path, but this will still only allow you to query the device, not set any parameters.

ok,now i moved to /usr/sbin and tried : ethtool eth0
but nothing happens.
I i also tried ls |grep ethtool in /usr/sbin dir
no output. What is the correct way to use ethtool if as a nornal user i can't use it.

Run either

~> /usr/sbin/ethtool eth0

or

/usr/sbin> ./ethtool eth0

If neither works, try logging in as root and running it, or run it via su/sudo

thanks pludi
I become root user and it works:
ethtool eth0

thanks,
