Hello,
I can tell my patch was adressing read file error on conf file,
but, unfortunately, not at all "dependencies of stunnel service at start up",
which is likely to be the core pb preventing stunnel to start correctly at boot time for people on that thread.

Michal added explicit dependencies at startup, that is necessary to solve that bug. I did not check yet its implementation.

But maybe some services, although started, are still "not ready" when stunnel starts, so that this makes stunnel fail.

I suggest that stunnel checks, not only the availability, but also the "efficiency" of the DNS service by trying to resolve a well known server.
it should retry during, eg, 3 seconds, and then stops with some reports if failing to resolve the hostname,
either by lack of network, or by lack of answer from the name resolver.
But...it seems that when having problems at startup, it cannot even log anything....maybe this is due to the identity of "system user" of stunnel at that particular moment: user that may have no right to write on the HD.

People should check also the installation location of stunnel : it is supposed (and have predefined shortcuts for that) to be installed PREFERABLY in "c:\program files\stunnel".
I recommend to use that location.

They also should try to resolve by hand the hostnames they put in their stunnel conf file, just to be sure.

On some network or machines, maybe there is a problem with the firewall and SOME services tunneled by stunnel on forbidden ports.

On another hand, it sounds strange that just restarting stunnel (in user mode or service mode ?) is solving the problem :
this sounds like unavailability of DNS at startup.

I did not investigate that particular problem, but I will perform some tests soon with the last 504 (or 505).

Yours sincerely
Pierre

Using Stunnel on several Windows Server 2008 R2 SP1 machines (all such machines are X64 as the OS is only released as X64).

During August of 2014 I reported in this forum the current version of Stunnel would not function as a service under the above OS, even if using a delayed start, it might run but it would not work. I reverted to using version 4.35, which did work properly.

Pierre DeLagge was kind enough to provide me with a copy of his patched Stunnel 5.02, which I am still using and which is working flawlessly on my production servers. No delayed start required.

I am wondering if Pierre's 5.02 patch has been incorporated into the most recently released Stunnel, 5.04? Has anyone been successful in getting the most current version to actually work under the above environment without delaying the start of the service?

Just to add a little color and background to the story, I am using the native WS2008R2SP1 SMTP server on each machine, in conjunction with Stunnel, so as to forward OS event notifications through a gmail account.

I tried 5.04. on Windows Server 2008 R2 Enterprise Service Pack 1 x64

Same issue. Service shows as started, but no log. If I go manual restart it works.

Have to put delayed startup.

For now i'm happy with 5.03 Already in production so I will have to wait next time! :)

Thank you for testing it.

Best regards,
