The code in the UW server which is compiled if UTMP is defined does write entries into "/etc/utmp". On some machines the utmp file is world-writeable (e.g. on Suns, so that "suntools" can write it); on others UW must be setuid or setgid in order to write it. The code in the server handles windows created from the Mac (with the "New" command in the "Window" menu) and windows created via "uwtool". "uwterm" does its own pseudo-terminal management and does not write into the utmp file. (I didn't have time to implement and test that before the last distribution.) A general word of advice: you should be very cautious about installing setuid/setgid programs. I advise you to look at any such program (certainly including the UW server) very carefully so that you understand the implications of installing it setuid or setgid. -- John Bruner (S-1 Project, Lawrence Livermore National Laboratory) MILNET: jdb@mordor.s1.gov (415) 422-0758 UUCP: ...!ucbvax!decwrl!mordor!jdb ...!seismo!mordor!jdb
