- In order to update the /etc/utmp file - to show that you are "logged"
- on to that tty, the Terminal App must be installed as suid root (sad
- but true). Could it be that Stuart also needs to be installed setuid
- root to solve this problem, and that you two haven't done this?
-
- Just a guess...
-
- BTW, having Terminal run as setuid root causes a bug with the preview
- function of the print panel. The PS tmp file created is owned by root,
- but created with the umask defined in the defaults DB. If you set up
- a umask to prevents others from reading your files, then you can't use
- the preview function from within terminal. You get a cannot open type
- of error messages from Preview - not that this is a real problem
- because who really needs to preview the output anyway. I wonder if
- they fixed this in 3.0? I'll know soon ....
-
- This also seemed like a potential security bug - but I couldn't figure
- out any way to take advantage of it.
