Dear Users, I have released version 4.50 of stunnel. The ChangeLog entry: Version 4.50, 2011.12.03, urgency: MEDIUM: * New features - Added Android port. - Updated INSTALL.FIPS. * Bugfixes - Fixed internal memory allocation problem in inetd mode. - Fixed FIPS mode on Microsoft Vista, Server 2008, and Windows 7. This fix required to compile OpenSSL FIPS-compliant DLLs with MSVC 9.0, instead of MSVC 10.0. msvcr100.dll was replaced with msvcr90.dll. GPL compatibility issues are explained in the GPL FAQ: http://www.gnu.org/licenses/gpl-faq.html#WindowsRuntimeAndGPL - POP3 server-side protocol negotiation updated to report STLS capability (thx to Anthony Morgan).

Hi Ludovic, You are right. With the new FIPS-compliant OpenSSL DLLs I stopped building them against ZLIB library. Not because it is technically impossible or very hard to do, but because it adds some additional complexity and it is not very useful (at least compared to FIPS). Please prove me wrong, and I will update the DLLs. Mike
Hi, Personally, we use stunnel for remote connection to our nntp server's office who is use like repository for our developpements and exchanges. Our database size is very big. So we use compression to exchange data between us to save bandwith. I think that lot of user take avantage of this feature (data compression) like http,nntp,imap ... based on heavy compressible text. So, i hope to see one day, come back of compression feature. Thank's for your jobs. Ludovic. Le 03/12/2011 18:58, Michal Trojnara a écrit :

I'm convinced. I'll try to find a few hours next week to build Zlib and to update OpenSSL. Mike
Hi Mike, Thank's for your quick job ! So, i have a good new and bad new. First : Good new It is working ! Second : Bad new Even if i remove on my conf file 'compression = zlib' (on server and client) the compression is enable. I have see that, by the cpu used by my server for the process stunnel. With version 4.50 (on the client) with a file (500MB) to transfert (at 3.5MB to my home), the cpu of server is at 15% for the process stunnel . With version 4.51b (on the client) with the same file at same speed take 85% of cpu for the process stunnel. Now, to disable compression on my client with 4.51b , i rename the zlib1.dll to zlib1.dll.bak and restart stunnel, after the same transfert take 15% - 18% of cpu on my server for the process stunnel . I think that openssl enable by default compression if remote openssl server suport it by default. my config : client : windows 7 64bits with stunnel 4.50 or 4.51b server : fedora i386 with openssl-1.0.0b and stunnel 4.50 (compiled from me) Thank's.

Hi mike, It seem that openssl since version 0.9.8b zlib compression is enable by default. This is the problem of cpu usage of stunnel. Is it possible to force it disable it by 'compression = none' in a next version of stunnel ? reference: http://www.mail-archive.com/[email protected]/msg49919.html Thank's. Ludovic.

I did some research and the facts are: 1. Stunnel code for "compression" option is obsolete since OpenSSL 0.9.8 (released 05 Jul 2005). The new implementation is compatible with: http://tools.ietf.org/html/rfc1951 2. Starting with OpenSSL 1.0.0 compression can be disabled with "options = NO_COMPRESSION" service-level option. 3. In OpenSSL version >= 0.9.8 and <1.0.0 there is currently no way to disable compression with an stunnel.conf option. My conclusion: I will add "compression = none" global option implemented as: #ifndef OPENSSL_NO_COMP sk_SSL_COMP_zero(SSL_COMP_get_compression_methods()); #endif Mike
I wrote:

On second thought: This might be probably even better to switch compression off by default. The memory and CPU requirements of compression probably make it a bad choice for ~90% of users. The available parameters will be: - deflate - RFC 3749 https://www.ietf.org/rfc/rfc3749.txt - zlib - OpenSSL 0.9.7 compatibility - rle - OpenSSL 0.9.7 compatibility The default will be to disable compression entirely. What do you think? Mike
Hi Mike, Yes, this is better to disable it by default. But do you project to return on openssl 1.0.0x for next release to control compression ? And why are you move from openssl 1.0.0 to 0.9.8 in version 4.48 to 4.49 ? (for FIPS i suppose) Thank's. Ludovic. Le 09/12/2011 18:46, Michal Trojnara a écrit :

No. Yes. Mike
So, For your next version (> 4.51) with update code for compression, i will replace openssl 0.9.8 by openssl 1.0.0e given from package 4.47 (for windows of course) then i'm will be able to control compression (but am lost FIPS, not very important for me). This is possible ? (i think...) Ludovic. Le 09/12/2011 19:31, Michal Trojnara a écrit :

1. This is not possible, as OpenSSL 0.9.8 shared library (DLLs) is not binary-compatible with OpenSSL 1.0.0 shared library. 2. This won't be needed, as compression control in stunnel 4.51 will also work with OpenSSL 0.9.8. Mike
Ok, So, i understand that the methode : sk_SSL_COMP_zero(SSL_COMP_get_compression_methods()); will work for 0.9.8 and 1.0.0 openssl.' So, on my server, i can compile version 4.51 on my linux box who have openssl 1.0.0 by default ant it will work (for global connection), i'm just haven't the possibility to disable compression per-connection (lack of SSL_CTX_set_options), but it is perfect for me.

Hi Mike, A quick question, I am trying to create a SSL connection using stunnel and the following configuration; debug = 7 output = stunnel.log ;cert = FCAXV_HamfbaaStkhlm1.pem key = FCAXV_HamfbaaStkhlm1_key.pem [SSLHOST] ;Use it for client mode client = yes accept = 127.0.0.1:2525 connect = <server-ip>:10170 And I am getting following log after starting the Stunnel. Does following "Configuration successful" message in the log means that I have established a SSl connection? I am wondering about this because I have not provided any password for the certificate-private key, infact I do not know to do that as well.

Wow - android binary! What does that mean? I ask that because my droid-foo is fairly low.
