Whenever I open the terminal on my Centos5.1, I always get this error
/root/.cshrc Permission denied
and then I can’t use networking commands (ip,ifconfig,…) because they are reported as unknown commands.
Verify that you have permissions to read .cshrc To do that issue:
ls -l /root/.cshrc
If the output begins with to dashes it means that you don’t. To give yourself read permission to this file issue:
chmod +r /root/.cshrc
Now if you run
ls -l /root/.cshrcthe output should start with-r.
