hanging processes

[Hans-Joachim . Schmidt]

Hello,

our users have access to our LINUX computer (with SuSE Linux 8.0 (i386) -
Kernel 2.4.18-64GB-SMP) with the Kermit terminal emulation on their PC's.

In this emulation they start programs that perhaps are waiting for answers
(read in a shell or in a program); when they close the Kermit window without
stoping the actual program, it can happen that this program 'hangs':

the initially process hierarchy is:

init
   inetd
      in.telnetd
         login
            bash
               program_waiting_for_an_answer


after stoping Kermit:

init
   login
      bash
         program_waiting_for_an_answer

When I see (with pstree, ps) that login is directly hanging on init, I know
there are perhaps hanging programs; by killing the program (by hand) also
the bash and login process disappear (what we want).

How can we reach that the 'program_waiting_for_an_answer' disappears with
inted, in.telnetd, login and bash when the Kermit window is closed by the
user and he has not completed the actual program in the LINUX shell before ?


We searched appropriate configurations for inet, in.telnetd and bash, but we
don't found them.

In our UNIX system V before we had not this problem.


Best regards
