Re: [stunnel-users] Question of stunnel/openssl for X86 processor -- Pierre's patch

Hi Jiehua, Please review the instructions on my webpage : in particular use my compilation scripts, and look inside them to know the syntax. It is quite simple : makece X86 for stunnel. For openssl, "mywcebuild X86". It works. Let me know if you have problems.

But the compilation failed, I got error messages as below. I'm also including all options for cl.exe in the email as well. I wonder if you have seen similar issues before.

RFC: purge use of keyword 'transparent'
by oscaruser＠programmer.net 08 Jan '11

08 Jan '11

Folks, After searching, installing various Linuces (in the 2.6 family), e.g. CentOS, Ubuntu, and so on, I have not been able to get transparent proxy working at all. As such since it the function does not work, and there is great debate as to whether it ever worked, I would like to propose that this keyword and reference to its function be discarded entirely. This will save many folks a great deal of time and effort attempting to try and get it to work, myself having spent over 80 hours (including my precious holiday time) trying to dig, scratch, research up old posts that say it works or someone has it working under such and such a configuration! The documentation itself has folks claiming that it works and does not, which is really a bad practice. Why did you perpetuate this option in the first place?! I hope you see the importance and reason with my request and act immediately. ... Unless someone really really does have it working. Thank you

How can I configure Intermediate Certificate
by Carlos García Villate 04 Jan '11

04 Jan '11

Hi. Two months ago, we installed our SSL certificate with stunnel succesfully. That certificate was issued by Verisign. We did not experience any issues. A few weeks ago, we had to renew that certficate and after doing that, we started to get 'Invalid certificate' errors form our web site users. It seems that the new certificate issued by Verisign, has changed its hierarchy, and browsers like FF that do not have one of the necessary intermediate certificate registered fail. This is the new hierarchy: - VeriSign Class 3 Public Primary Certification Authority - G5 - VeriSign Class 3 Secure Server CA - G3 - www.b-kin.com It is the 'VeriSign Class 3 Secure Server CA - G3' certificate the one that most FF browsers do not have registered, and so the browsers reject the request with an 'Invalid certificate' message. To solve this issue, we are trying to incorporate the 'VeriSign Class 3 Secure Server CA - G3' certificate in the .pem file, where our www.b-kin.comcertificate is installed. We have tried to include the Verisign certificate first and then the other one; and the other way round, first our certificate and then the Verisign one, but without success. The Verisign certificate has been directly taken from the Verisign web site. The .pem file has following structure: Bag Attributes heading section ..... -----BEGIN RSA PRIVATE KEY----- ..... -----END RSA PRIVATE KEY----- Bag Attributes heading section -----BEGIN CERTIFICATE----- /*We have alternated to put here the www.b-kin.com or the Verisign certificate*/ ..... -----END CERTIFICATE----- Bag Attributes heading section -----BEGIN CERTIFICATE----- /*We have alternated to put here the www.b-kin.com or the Verisign certificate*/ ..... -----END CERTIFICATE----- We are running stunnel on CentOS with the following configuration: stunnel 4.32 on i686-pc-linux-gnu with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 Threading:PTHREAD SSL:ENGINE,FIPS Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = daemon.notice pid = /usr/local/var/run/stunnel/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = FIPS session = 300 seconds stack = 65536 bytes sslVersion = TLSv1 TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none As we have seen in the documentation, it is possible to include a certificate hierarchy in a .pem file. What we do not know is the order nor the values to set int Bag Attributes heading section, for the Verisign certificate. Best regards, Carlos.

Dear Michal Trojnara, Some protocols (e.g. ssh,vpn...) must install software in SERVER side. I want to understand the fact below: If only the CLIENT side can install the special software. What is the special software? Is it possible to encrypt the Web server IP ,URL ,Data??? If stunnel can solve this issue. How to configure?

Experimental stunnel-4.35b1
by Michal Trojnara 15 Dec '10

15 Dec '10

Dear Users, I have uploaded stunnel-4.35b1 to ftp://stunnel.mirt.net/stunnel/ for your testing. Please give it a shot and submit any problems to stunnel-users mailing list. This is the way you can not only help me improve production 4.35, but also make sure it's going to work on your platform! Please consider version 4.35b1 highly experimental and not ready for production. Specifically it is no supposed to be packaged for any OS distribution (e.g. *BSD ports). Best regards, Michal Trojnara

endpoints using different versions of stunnel
by nishith n 15 Dec '10

15 Dec '10

Hello all, We have a client who would like to send us data using stunnel 4.33 at their end of the connection. Can we establish connection from our end using stunnel 4.11 version. We are working on a sun machine. I know I can simply download the latest stunnel version but it has to go through an authorization process which probably will take more time than I have and hence this question. What could be the impacts to connectivity or otherwise with such a setup? Thanks for your replies, Nishith

Dear friends, After reading mailing lists & Web & FAQ I couldn't find answers to these: stunnel.conf as follows: debug=7 client = yes [proxy] accept=1111 connect=62.215.5.69:8080 (Public SSL Proxy) protocol=connect protocolHost=stunnel.mirt.net:443 CLIENT(Browser+Special software)<->firewall<->(Internet)<->Public SSL Proxy<->WEB SERVER Public SSL Proxy as follows: http://tools.rosinstrument.com/raw_free_db.htm?t=2 Only the CLIENT side have stunnel. After running stunnel 4.34 (Windows binaries). Then. Browser http://localhost:1111/ But Sniffer can monitor the command-(CONNECT stunnel.mirt.net:443). The problem as follows: Only the CLIENT side can install special software. Special software including but not limited to stunnel. If the firewall can block many websites depend on Web IP & URL. How to pass through the firewall base on Public SSL Proxy? How to encrypt the URL-(stunnel.mirt.net:443)? What is the special software? If stunnel can solve this issue. How to configure? Best regards, cpu
