Thanks. Perhaps I am misunderstanding revoke(2). It sounds like that
is something I should be doing after I use openpty(3) so that the
initial connection will not be confused with any prior ones. However,
my problem is not with the first connection; that works fine. The
problem is after a connection is made with tip(1) and disconnected with
'~^D' then a subsequent connection fails (unless done by root).
If I am to do another revoke(2) call, when should I do that? How will
I know that the first connection has been disconnected? If I just
timeout after inactivity will the fact that the slave side of the
pty(4) disappears create problems for clients that were just inactive
but still connected?
Thanks for the help.
