TTYGROUP (string) TTYPERM (string) The terminal permissions: the login tty will be owned by the TTYGROUP group, and the permissions will be set to TTYPERM. TTYGROUP can be either the name of a group or a numeric group identifier. If TTYGROUP is not defined, then the group ownership of the terminal is set to the user's primary group. If TTYPERM is not defined, then the permissions are set to 0600. If you have a write program which is "setgid" to a special group which owns the terminals, define TTYGROUP to the group number and TTYPERM to 0620. Otherwise leave TTYGROUP commented out and assign TTYPERM to either 622 or 600.
