Linux question

How do you get denied permission to /etc/fstab when you're root, and logged in as such?

Also, the STMP shutdown failed. Anyone have any ideas as to how to remedy?

Thanks!

can you post a typescript of what exactlly you're trying to do:

ls -latr /etc/fstab

also, can you check your logs for the smtp shutdown ...

tail /var/log/maillog

Files can be marked read-only, and most editors will at least partially honor that setting even if you're root. For instance, in vi, you may need :w! instead of :w to write a file marked as read-only - including, say, a file you already have open in another window.

The permissions are a grid, 3x3. It looks like this:
______ Owner Group Other
Read___[]_____[]____[]
Write___[]_____[]____[]
Execute_[]_____[]____[]

Which means it is possible to block even the owner from reading, writing, or executing the file. That doesn't however, mean that the owner can't change the permissions on the file. So just change the permissions so you(root) can read and write the file. I forget which number code that is. 644 is for rw-r--r--...maybe 600 is for rw-------.
