This version should be thoroughly tested before using it in the mission-critical environment. Home page & downloads: http://stunnel.mirt.net/ Best regards, Mike

openssl - generating stunnel.pem - stunnel.cnf
by k-i-r＠web.de 24 Feb '05

24 Feb '05

Using Stunnel under Windows I want to create a certificate (stunnel.pem) with Openssl. According to FAQ the syntax for creating a certificate with Openssl is openssl req -new -x509 -days 365 -nodes -config stunnel.cnf -out stunnel.pem -keyout stunnel.pem I use openssl for windows (as part of apache-windows-http-server) . Where do I get the file stunnel.cnf ? Or is this file not necessary for creating a certificate ? Thanks for help, k.

Stunnel and configuration
by Bohdan Linda 22 Feb '05

22 Feb '05

Hi all, I have configured stunnel to do the client authetication, but I have some question. I have used following config: cert = /etc/certificates/server.pem - file with signed server cert and key (passwordless) chroot = /var/run/stunnel/ CAfile = /etc/certificates/certs -file where first item is my CA certificate followed by list of all client certificates sgined by my CA. setuid = nobody setgid = nogroup pid = /stunnel.pid verify = 3 This setup is working, but this seems to me very "unlogical". If I create for me "more logic" setup: cert = /etc/certificates/server.pem chroot = /var/run/stunnel/ CAfile = /etc/certificates/CA/cacert.pem - only certificate of my CA CRLfile = /etc/certificates/crls - only certificates signed by my CA I get the following error: 2005.02.22 15:15:10 LOG5[22418:81926]: VERIFY OK: depth=1, /C= ..... 2005.02.22 15:15:10 LOG4[22418:81926]: VERIFY ERROR ONLY MY: no cert for /C= The question is ... why? Why CAfile has to contain all client certificates, when clients certs are not CA? Why I cannot have separate file for CA and separate file for certificates that I want accept? If I do the similar setup in mod_ssl, the configuration works as expected. Anyway, I'am newbie to deploy stunnel, thus I would like to ask you for giving me you opinion of this configuration, caveats and possible enhancements. Thanks for any comments, Bohdan Linda

I'm NOT going to break SSL protocol in stunnel to support broken SSL clients. Use: TIMEOUTclose = 0 configuration option instead. Best regards, Mike
