Trouble sending email via smtp with a particular gmail address
by Brian Morgan 01 Nov '13

01 Nov '13

I'm having trouble sending email through stunnel with our customer service email address. We use google premium services for our hosted email. I can send through stunnel using my own personal account, but when I switch to the cust service account, I get the error: "Failed to send an E-mail through the specified SMTP server [127.0.0.1]: The SMTP server requires a secure connection or the client was not authenticated. The server response was 5.5.1 Authentication Required." And yes, I double/triple checked credentials and can login through the gmail interface with them just fine. I also tried changing the password to a strong password which did not help. gmail settings in stunnel.conf: [gmail-smtp] client = yes accept = 127.0.0.1:259 connect = smtp.gmail.com:465 I also tried port 587 but that produces another error: "Failed to send an E-mail through the specified SMTP server [127.0.0.1]: Failure sending mail." Any ideas?

Question Regarding Client Installer
by Andrew Smith 29 Oct '13

29 Oct '13

We currently use Stunnel to allow our clients to connect to their Databases that are hosted by us. I think this product is great. However, I am a newbie to Stunnel as our previous resource has passed away. What I would like to know now to do is create an installer for clients machines that have the correct configuration files in etc... I am sure this is pretty easy and I will be able to do it this once I am guided in the correct direction. Thanks in advance! ________________________________ Andrew Smith Support Technical Services Analyst P: 614-875-4910 x109 F: 614-875-4088 E: andrew.smith(a)harriscomputer.com [http://www.harriscomputer.com/images/signatures/HarrisSchools.jpg] [http://www.harriscomputer.com/images/signatures/DivisionofHarris.gif]<http://www.harriscomputer.com/> 6110 Enterprise Parkway Grove City, OH 43123 www.harris-schoolsolutions.com<http://www.harris-schoolsolutions.com> This message is intended exclusively for the individual or entity to which it is addressed.

Re: [stunnel-users] Is it usual/recommended to have key and cert in ONE stunnel.pem file?
by Ben Stover 29 Oct '13

29 Oct '13

Hello John, thank you for your clarification. Two more additional questions: According to stunnel guide I created a cert + key with the following command: openssl.exe req -new -x509 -days 3650 -nodes -config stunnel.cnf -out stunnelcert.pem -keyout stunnelkey.pem 1.) For what do I need here the -config stunnel.cnf parameter? I am prompted by openssl for the content values during generation anyway. Can stunnel.cnf be seen only as a default value pattern for the created cert during generation? Can I omit this parameter? 2.) After creation of cert+key I have to specify them (as client) in stunnel.conf (with "o") as follows: cert = stunnelcert.pem key = stunnelkey.pem Is this sufficient?

Hello John, That sort of falls into the "tragedy waiting to happen" category. The certificate is supposed to be given to clients, and the key belongs to the server and has to be kept private or there's really no point in using SSL. > Or should user put these two parts in two independent files? Yes, absolutely. In fact I suppose you're using Windows or went through some hoop-jumping to combine them, because in "normal" OpenSSL usage the key is generated first and then the certs are requested and signed by the CA (or selfsigning) key. /jl

VPAT Section 508 Compliance
by Tracy Drake - QI-C 28 Oct '13

28 Oct '13

Hello Stunnel Support! I am seeking a VPAT showing the level Sec 508 compliance so that we can move toward making Stunnel a GSA-approved software. I guess the biggest question is whether or not Stunnel is considered to be section 508 compliant. Please advise as to where/how I can obtain this information. -- Tracy Drake CSM Senior Consultant GSA-FAS FAME Contractor URSA & INFOConnect Support & Training Team Lead 704-987-1211 tracy.drake(a)gsa.gov

Is it usual/recommended to have key and cert in ONE stunnel.pem file?
by Ben Stover 28 Oct '13

28 Oct '13

According to some tutorial pages I generated with OpenSSL a (selfsigned) certificate. This file stunnel.pem contains the certifictae as well as the private key. Is this usual/recommended? Or should user put these two parts in two independent files? Ben

Verify = 4 Fails Yet Again
by Thomas Eifert 25 Oct '13

25 Oct '13

I've just encountered another situation in which verify = 4 fails on a seemingly valid certificate. Since I've previously posted details regarding this issue, I'm only going to post the certificate here. This is the 3rd certificate I've run across in the past 6 months that fails to verify. Can all 3 of the certificates be faulty, or is there an issue with Stunnel or OpenSSL here?

Stunnel Service as other user
by Florian Götz 24 Oct '13

24 Oct '13

Hi Stunnel users, if I use xinetd to start a service I got the possibility to start the service with a dedicated user. For example: service fex { socket_type = stream wait = no type = unlisted protocol = tcp bind = 123.12.1.12 port = 80 cps = 10 2 * user = fex groups = yes server = /home/fex/bin/fexsrv nice = 0 disable = no } I got some kind of webserver (not apache, nginx etc) that needs to be started with xinetd (the example above). This server should get a SSL tunnel. If I use Stunnel in daemon mode (without jails/chroot) and define a service like this: [https] accept = 123.12.1.12:443 exec = /home/fex/bin/fexsrv execargs = fexsrv stunnel TIMEOUTclose = 2 Everything works fine, except that the server now runs as root. Is there a possibility to set a user for a service? Best regards Florian Götz -- Mit freundlichen Grüßen Florian Götz ----------------------------------------------------------------- Dipl.-Inf.
