471.0. ""Can not create temporary node ; Can't set terminal secureity level"" by SMURF::BAT (Segui la tua beatitudine) Fri Apr 04 1997 17:19

    Chris Wolf (415) 506-2529 called with a problem.  Users trying to
    rlogin or telnet into the system would get rejected with the following
    messages:
    
    "Can not create temporary node"
    "Can't set terminal security level"
    
    I found the messages in sec_login.c -- evidently there was a  -t file
    created (by who knows? did the system crash in the middle of a
    create_file_securely?) in /dev/ for the "next" pseudo-tty that login
    was trying to allocate to a new user.  By moving them back to the file
    they should be or removing them and re-mknoding the pseudo-tty, Chris
    was able to get people to login again.
    
    It would be nice if the system did some integrity checking for -t files
    and notifying the user on reboot instead of just setting the attributes 
    and letting people hang in the wind.  Or it might be nice if the system
    would bullet-proof create_file_securely better.  It would be even
    better if the system didn't crash :-)
