Hi,
There appears to be a limit to the number of services you can define. Services beyond the 64th service appear to get set up without any log warnings or errors, yet don't pass traffic.
The code uses select() & FD_SET to accept() an incoming connection & in Windows (using Windows Server 2008) the default is 64 sockets for that so wondering if I can just recompile, setting FD_SETSIZE to something larger.
I'll try it either way, just wanted to put it out there to see if anyone else has ever run into this.
Thanks, Terren
It is possible to setup stunnel as separate services. I don't know if this would be a suitable workaround for you.

Hi Brian - just to clarify, you mean running multiple instances of stunnel correct?

Hi,
Since, I can't recall the version (edit: probably since 4.16 as Michal stated in the link below), it is not possible to run more than one instance of stunnel. You can just create service level configurations in the conf file and nothing else. (Previously I, myself, had 2 conf files for client and server too)
If there are only allowed 64 services (and therefore ports), I think it might be considered as a new feature to add or as a bug.
I never need such ammount of services, but could be interesting to fix and allow more. I wouldn't say 65535 minus 1028 but a few more ;-)
Regards.

Yes, you can. I currently do it. On Apr 5, 2013 12:19 PM, "Javier" [email protected] wrote:

Hi,
But, don't stop there ;-) How do you do it?
I'm talking about the windows binary, not the unix one or a cooked one (recompiled) with such feature.
At least in my case, I can't and/or I don't find in the manual any option to have more instances.
Any help is really appreciated :-)
Regards.
I simply have two entries in services. It requires editing the registry and giving two different names to the service entries, for instance stunnel-client and stunnel-server. You can call different config files too.

Hi,
Ok, I've played a little with your explanation and SrvAny (link below) and I found that is not exactly as you tell, at least under Windows 2000.
I didn't know this, but stunnel can run several instances just renaming the stunnel.exe executable, because what stunnel checks only is the PID name not whatever others applications check to check if it is already running. So just changing the executable name of every stunnel.exe copy is enough to have several intances running.
About the services, it is not as you told (with my tests). I created two services, but if they call to the same executable the behavior is as expected: unable to run 2 or more instances. It only works if you link each service with a different named executable. Lets say we create service "stn1" and "stn2"; "stn1" should call to "stunnel1.exe" and "stn2" should call to "stunnel2.exe". Of course, each one can take each own .conf file.
Anyway, it was interesting to find out this :-)

Windows 2000.... I have not used that in years. I was referring to XP and I do not need to rename the executable. The executable name should have no bearing on the PID. On Apr 6, 2013 11:34 AM, "Javier" [email protected] wrote:

Below is a link to a tutorial I wrote on how to setup stunnel to run as two services.. it's not really necessary anymore because stunnel can do this natively but some people may still benefit from doing it this way.

Hi,
Ok, it works and in a more elegant way than renaming :-)
Something is added (someday I'll check what exactly) to the service keys that isn't added with Srvany utility that lets the execution of both instances with the same executable name. Probably is that the main executable (image path) isn't the Stunnel executable. Maybe the magic and the lack of that utility.
Anyway, all methods are valid and is great to know about them :-)
Thanks for your tutorial. Regards.
