close tcp port
Hello, I have a service running (ODBC) and every now and then it will hang and I will have to stop and restart the service. The problem is when I stop the service, it indeed stops the service, but netstat reports a tcp port still open with the fin_wait_2 status. Then I must close the client application to allow the service to restart or wait 5 minutes. How do I make it close automatically and not wait for 5 minutes? I thought maybe if I defined the service in /etc/inted.conf as nowait it might help but either that is not how it's done or that just doesn't work that way.

I added this: (copied from another service in the file and adapted it)

tfodbc stream tcp nowait root /usr/local/tsobdc/tfodbc.sh start

It did not break the service, it still works fine. There is also /etc/services. can I add anything to that to define this program as a service and have it so that when it stops running it closes its ports? This is AIX 4.3

Thanks

services(4)						     Kernel Interfaces Manual						       services(4)

NAME

       services - Defines the sockets and protocols used for Internet services

SYNOPSIS

       /etc/services

DESCRIPTION

       The  /etc/services  file associates Internet service names and aliases with the port number and protocol used by the service.  Each service
       is listed in this file on a single line of the form: ServiceName  PortNumber/ProtocolName  Aliases

       The fields contain the following information: The official Internet service name.  The socket port number used  for  the  service  and  the
       transport protocol used for the service.  A list of unofficial service names.

       Items on a line are separated by spaces or tabs.  Comments begin with a # (number sign) and continue to the end of the line.

EXAMPLES

       Entries	in  the  /etc/services	file for the inetd internal services might look like this: echo 	 7/tcp echo	     7/udp discard
       9/tcp	  sink null discard	  9/udp      sink null daytime	    13/tcp daytime	 13/udp  chargen       19/tcp	    ttytst  source
       chargen	    19/tcp	ttytst source ftp	   21/tcp time	       37/tcp	   timeserver time	   37/udp      timeserver
