My problem startet with my RedHat 9 server, i edited the file "/etc/rc.local".

Then the server began doing some strange things and after some time i did not gett accses to the server any more. So what i need to do is edit this file inn Knoppix. But when i edit "rc.local" inn vim i get this message when i try to save the file "E45: 'readonly' optin is set <use ! to override>", i tried to to chmod 755 the file too, then i get this "chmod: changing premissions of `rc.local': Read-only file system".


So can anyone pleease tell me what to do ?
Or why i cant edit this file inn Knoppix ?
