Hi Claus, Exactly, you and I are the same method. Right now, I am using stunnel 3.24 for years that I have no problem with this one. Yes, I do have telnetd enable through inetd like this: telnet stream tcp6 nowait root /usr/sbin/tcpd /usr/sbin/telnetd -a We are using tcp-wrappers which is required. Hope it helps...

Hi Tom, I'm not sure why the stunnel process dies for you. I have several processes running using config files similar to what I included earlier. We generally create one config file per service. So if I was to run an TSSL service like you then I'd have a config file called /etc/stunnel/stunnel_tssl.conf ... and the service is started from /etc/inittab with a line like this: stunnel_tssl:2:once:/usr/local/bin/stunnel /etc/stunnel/stunnel_tssl.conf >/dev/console I haven't experienced any problems with the stunnel process not staying alive... And the process I started early this morning on my test box is still alive: clund@prod-db-2:/home/clund $ ps -ef|grep stunnel nobody 1233036 1 0 08:15:28 - 0:00 /usr/local/bin/stunnel /etc/stunnel/stunnel_tssl.conf -Claus ____________________________________________ Claus Lund Systems Developer Vermont Department of Taxes Information Systems 133 State Street Montpelier, Vermont 05633-1401 (802) 828-3735 -----Original Message----- From: Spence, Thomas Civ 844 CS/SCBX [mailto:Thomas.Spence@pentagon.af.mil] Sent: Thursday, January 22, 2009 10:26 AM To: Lund, Claus; stunnel-announce@mirt.net; stunnel-users@mirt.net Subject: RE: Stunnel 4.26 - AIX 5.3 Claus, After I type: # stunnel # ps -ef | grep stunnel stunnel 295006 1 0 09:49:38 pts/2 0:00 /usr/local/bin/stunnel stunnel 348182 1 0 09:49:38 pts/2 0:00 /usr/local/bin/stunnel stunnel 454872 1 0 09:49:38 pts/2 0:00 /usr/local/bin/stunnel stunnel 458864 1 0 09:49:38 pts/2 0:00 /usr/local/bin/stunnel stunnel 589834 1 0 09:49:38 - 0:00 /usr/local/bin/stunnel stunnel 634882 1 0 09:49:38 pts/2 0:00 /usr/local/bin/stunnel root 643180 463028 0 09:49:40 pts/2 0:00 grep stunnel About 10 minutes later, # ps -ef | grep stunnel root 381102 463028 0 10:03:59 pts/2 0:00 grep stunnel Any idea why?

And I know that way back when, I was doing some testing with a similar setup and was never successful getting the "exec = telnetd" to work quite right when stunnel was running as a service. I did some quick testing right now on one of our AIX boxes (using stunnel 4.22) and it doesn't work for me either. Everything looks fine when stunnel is started and the first connection comes along and works beautifully... But then stunnel dies after the connection is closed. I assume you're using the exec = /usr/bin/telnetd option because you don't have telnetd enabled through inetd? We can't generally run telnetd either so I understand that requirement. But maybe you can get a waiver and leave it running behind a port that only accepts local connections? _______________________________ Claus Lund System Developer Vermont Department of Taxes 802-828-3735 -----Original Message----- From: stunnel-users-bounces@mirt.net [mailto:stunnel-users-bounces@mirt.net] On Behalf Of Spence, Thomas Civ 844 CS/SCBX Sent: Wednesday, January 21, 2009 4:59 PM To: stunnel-announce@mirt.net; stunnel-users@mirt.net Subject: [stunnel-users] Stunnel 4.26 -

Hi Lars, I checked out your previous mails... And I don't know if it's related. I haven't dived into the code or done any extensive testing to try to figure out why Stunnel was failing when using "exec = ...". And I haven't had any problems when using it the way we do.

Could you try to run stunnel from a terminal instead? I can (and did yesterday when I was helping Tom) ... but I'm not entirely sure what you'd like me to test :-)

I'm not sure why the stunnel process dies for you.

maybe I am wrong, but I could imagine, that this issue is related to the behaviour that I described in my mail to this list (sent on the 10th of January).

I have several processes running using config files similar to what I included earlier. We generally create one config file per service. So if I was to run an TSSL service like you then I'd have a config file called /etc/stunnel/stunnel_tssl.conf ... and the service is started from /etc/inittab with a line like this:

stunnel_tssl:2:once:/usr/local/bin/stunnel /etc/stunnel/stunnel_tssl.conf

...

/dev/console

I haven't experienced any problems with the stunnel process not staying alive... And the process I started early this morning on my test box is still alive:

clund@prod-db-2:/home/clund $ ps -ef|grep stunnel nobody 1233036 1 0 08:15:28 - 0:00 /usr/local/bin/stunnel /etc/stunnel/stunnel_tssl.conf

I guess, the initial /sbin/init is not connected to a terminal - thus the "tty" column is always empty in your setup. Could you try to run stunnel from a terminal instead? Or am I completely off-track? regards, Lars _______________________________________________ stunnel-users mailing list stunnel-users@mirt.net http://stunnel.mirt.net/mailman/listinfo/stunnel-users From: stunnel-users-bounces@mirt.net [mailto:stunnel-users-bounces@mirt.net] On Behalf Of stephan.w.schindehette@jpmchase.com Sent: Thursday, January 22, 2009 4:41 PM To: stunnel-users@mirt.net Subject: Re: [stunnel-users] Stunnel 4.26 - AIX 5.3 I'm running into the same issue on one of our AIX boxes (using stunnel 4.22).

Ah! Well, I build stunnel with: --disable-libwrap :-) -Claus -----Original Message----- From: stunnel-users-bounces@mirt.net [mailto:stunnel-users-bounces@mirt.net] On Behalf Of Lars Kruse Sent: Saturday, January 24, 2009 12:16 PM To: stunnel-users@mirt.net Subject: Re: [stunnel-users] Stunnel 4.26 - AIX 5.3 Hi Claus, Am Fri, 23 Jan 2009 07:55:05 -0500 schrieb "Lund, Claus" <Claus.Lund@state.vt.us>:

I checked out your previous mails... And I don't know if it's related. I haven't dived into the code or done any extensive testing to try to figure out why Stunnel was failing when using "exec = ...". And I haven't had any problems when using it the way we do.

the "exec" issue is not the point, that was problematic for me. The problem is the still open stdout/stderr file handle. See my mail from the 10th of January for details.

...

Could you try to run stunnel from a terminal instead? I can (and did yesterday when I was helping Tom) ... but I'm not entirely sure what you'd like me to test :-)

I did the following: 1) running stunnel 4.20 (no separate libwrap): The stunnel processes are properly disconnected from stdout/stderr. See the output of "ps" - especially the "tty" column. 2) running stunnel 4.21 (with libwrap): The stunnel processes (except for one) are still connected to stdout/stderr. This can cause programs to hang (e.g. the cryptonas python code, that I referred to, was waiting forever for the daemon process to finish/disconnect - with 4.20 it worked). 3) running stunnel 4.21 (disabled libwrap): The stunnel processes are disconnected from stdout/stderr. It behaves just like 4.20 - no hang or other problems. If you notice above behaviour (2) for 4.21 (or later) with libwrap enabled, then I guess, this is a problem, or? At least, I expected stunnel to disconnect completely from the terminal when entering daemon mode. If my expectations are flawed here, then we all can safely ignore this non-issue :) thanks for your time!
