I had to run ethtool to config my network speed. I logged in as my normal user (Vepe) and ...
[Vepe@Vepe-PC ~]$ ethtool
bash: ethtool: command not found
[Vepe@Vepe-PC ~]$ sudo ethtool
sudo: /etc/sudoers is mode 0666, should be 0440
[Vepe@Vepe-PC ~]$ su root
Senha:
[root@Vepe-PC Vepe]# ethtool
bash: ethtool: command not found
[root@Vepe-PC Vepe]#
After that I logged as root and ethtool worked fine... Is there anyway for ethtool works with Vepe???
