changing /cn@0:console file permissions
I'm doing a security sweep of a Sun Sol 5.8 system. The file: /dev/console, which links to /devices/pseudo/cn@0:console, has the following perms: crw--w--w- I would like to get rid of the world write permissions. I can change the file permissions, but as soon as log back in, they are changed back to the original settings. Any one have any ideas of what is causing this? Thanks.
