The first > question being: is this worth it? :) what are the security issues of write(1)? You want to have `mesg no` for all terminals, such that nobody could use write anymore except for root? (I didn't look at the guts of tty, only at write(1) sourcecode) I would not consider a special daemon a solution for this issue. One of the great advantages of write(1) is its simplicity. You need nothing running, even with a totally broken system you should be able to write(1) other users. An administrator deactivating that daemon would be more common than an administrator really caring for deactivating things to make write unusable. Regards, Julian
