Make a file not overwriteable
Hi, I don't know why, whenever I "touched" my admin network options, it tries to overwrite my /etc/resolve.conf file, and this causes me not able to connect to the www properly. I have to take some time to figure out this problem when it occurs and I have to login as root to edit the file. I wish to make the file not overwriteable. I already chmod the file to 444 only, but it seems still to be able to be overwrited, the system seems to have the power of root. I wonder if I could "fix" the file somehow so that the system can't modify it.
