[K12OSN] home directory permissions

Hmm. The default user setup is 700. So unless the students are changing
things something is wrong with the permission controls from Likewise.

chmod 700 /home/*

That will reset the permissions on all directories in /home .
If the problem recurs, make it a cron job as follows:

crontab -e

Now PgDn to the bottom of the file and hit "A" (capital letter A for
Append) and hit the enter to start a new line

now type in:

* 7,11 * * * chmod 700 /home/*

then hit <Esc> then :wq

(yes this is a vi environment - it's good to know at least the basics!)

So now, every day at 7 and 11 am all directories will be reset to perms
700. If you want to do it every 2 hours, change the 7,11 to be */2 . If
you want 3pm only, use 15 instead of 7,11 .

If you don't want an email of everytime it runs make the first line of
the crontab :


But I would look into WHY and HOW the perms were changed in the first
place. Something is amiss!
