Operating Systems AIX Problem opening port 9998 Post 83851 by erica057 on Tuesday 20th of September 2005 08:39:40 AM

Thank you bakunin! I see that I was getting my terminology confused; thank you for the explanation. Yes, I was trying to create a daemon that listens on port 9998. Here is what I did:

First, I added this to /etc/services

Code:
tcpTest     9998/udp

Then, I added this to inetd.conf

Code:
tcpTest  stream  tcp  nowait  root  /path/to/a.out  a.out

(yes, I know that a.out is a generic name, this is the path to a specific binary).

tcpTest is present when I type "smit inetdconf".

I tried first refreshing inetd.conf, then killing inetd.conf and restarting it, and it did not work. It does not show up when I type ps, nor when I telnet into port 9998, nor when I scan it with nmap. When I type "startsrc -s tcpTest", it says "0513-085 the tcpTest Subsystem is not on file". It works when I try to start, say, tftpd, so I'm not sure what file it is pulling from.

Any thoughts?

Thanks in advance!
--Erica

EDIT: I also tried adding it to inittab to no avail.

recserv

recserv(1M)															       recserv(1M)

NAME

       recserv - HP SharedX Receiver Service

SYNOPSIS

       /usr/lbin/recserv

DESCRIPTION

       HP  SharedX  Receiver Service provides a method for a receiver to allow the sharing of windows without explicitly performing any xhost com-
       mands.  The Internet daemon (inetd(1M)) executes recserv when it receives a service request at the port listed in the  services	data  base
       for recserv (see inetd(1m) and services(4)).

       When recserv is executed via inetd, a dialog box appears informing the receiver of the share request by the sender.  The receiver can allow
       or disallow the share request by selecting the YES or NO button.

       recserv allows sharing by xhosting the sender just long enough for it to make a connection to the receiver.  Once the connection is  estab-
       lished  recserv	removes  the sender from the access control list, unless the sender was entered in the list prior to the execution of rec-
       serv.  Since no permanent change is made to the access control list, security is maintained at its highest level.

       To start recserv from the Internet daemon, the configuration file /etc/inetd.conf must include the single line entry,

       recserv	stream tcp nowait bin /usr/lbin/recserv  recserv -display :0

       If the sharing is going to be done between IPv6 machines, the protocol field of the above entry in /etc/inetd.conf  file  of  the  receiver
       machine should be changed to tcp6 as follows

       recserv	stream tcp6 nowait bin /usr/lbin/recserv  recserv -display :0

       and the services file /etc/services must include the line,

       recserv	       7815/tcp 	    # SharedX Receiver Service

       Receiver  Service  options,  set by selecting the Options button, dictate the behavior of recserv.  The behavior can also be set by running
       recserv manually.  In either case, an X server resource is set dictating the behavior for subsequent invocations of recserv.

OPTIONS

       The following options allow different behavior according to user preferences.

	      AlwaysAsk
		     The dialog will pop up each time sharing is requested, regardless of the security on your X server.

	      AlwaysAllow
		     The dialog box never appears, but sharing will always be allowed.

	      AskUnhosted
		     The dialog will pop up only if the sender's machine is not hosted on your	machine.   If  the  sender's  machine  is  already
		     hosted, sharing will occur without a dialog appearing.

	      NeverAsk
		     The dialog will never appear.  Windows are shared only if the sender's machine is already hosted by your server.
       To set resources (system behavior, label strings, etc) globally for a system, edit the file /usr/lib/X11/app-defaults/RecServ.
