Stunnel & Java SSL
by richard＠oversight.co.nz 28 Oct '04

28 Oct '04

I'm developing a website where a java applet is downloaded over an https session provided by Stunnel (stunnel 4.04 on i586-pc-linux-gnu PTHREAD with OpenSSL 0.9.6c 21 dec 2001) running on port 1080. The applet codebase in the html code is set to https://x.x.x.x:1080/xxxx.jar To complicate this issue, Stunnel is set to verify=3 i.e. it requires a valid client certificate. It seems that the java implementation of SSL (JVM 1.4.1_03) won't respond to prompts for client certificates?? Stunnel simply times out with the following error.... 2004.10.29 11:45:34 LOG7[6881:1024]: service accepted FD=10 from 192.168.1.2:19302004.10.29 11:45:34 LOG7[6881:1024]: FD 10 in non-blocking mode 2004.10.29 11:45:34 LOG7[6897:6146]: service finished (0 left) 2004.10.29 11:45:34 LOG7[6898:7171]: service started 2004.10.29 11:45:34 LOG5[6898:7171]: service connected from 192.168.1.2:1930 2004.10.29 11:45:34 LOG7[6898:7171]: SSL state (accept): before/accept initialization2004.10.29 11:45:34 LOG7[6898:7171]: waitforsocket: FD=10, DIR=read 2004.10.29 11:45:39 LOG7[6898:7171]: waitforsocket: ok 2004.10.29 11:45:39 LOG7[6898:7171]: SSL state (accept): SSLv3 read client hello A2004.10.29 11:45:39 LOG7[6898:7171]: SSL state (accept): SSLv3 write server hello A2004.10.29 11:45:39 LOG7[6898:7171]: SSL state (accept): SSLv3 write certificate A2004.10.29 11:45:39 LOG7[6898:7171]: SSL state (accept): SSLv3 write certificate request A2004.10.29 11:45:39 LOG7[6898:7171]: SSL state (accept): SSLv3 flush data 2004.10.29 11:45:39 LOG7[6898:7171]: waitforsocket: FD=10, DIR=read 2004.10.29 11:45:39 LOG7[6898:7171]: waitforsocket: ok 2004.10.29 11:45:39 LOG7[6898:7171]: SSL alert (read): warning: no certificate2004.10.29 11:45:39 LOG7[6898:7171]: waitforsocket: FD=10, DIR=read 2004.10.29 11:45:39 LOG7[6898:7171]: waitforsocket: ok 2004.10.29 11:45:39 LOG7[6898:7171]: SSL alert (write): fatal: handshake failure2004.10.29 11:45:39 LOG3[6898:7171]: SSL_accept: 140890C7: error:140890C7:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:peer did not return a certificate2004.10.29 11:45:39 LOG7[6898:7171]: service finished (0 left) Does anyone know a way around this?

Session resumption
by Rick Cone, Secure Payment Systems 27 Oct '04

27 Oct '04

I use Stunnel 4.03 I have been working on a project with some slow POS equipment trying to do SSL connections. Because of the slow processors on these devices, we are trying to speed up the connection and transaction. The concept of "session resumption" came up. What is the best way to setup Stunnel to make subsequent connections faster with session resumption. Thanks, Rick Cone Secure Payment Systems 801 8th St. #150-D Greeley, CO 80631 970-352-9434 (office) 970-352-0122 (fax, call office first) rcone(a)securepaymentsystems.com Note: This electronic message and attachments, if any, contain information which is intended solely for the designated recipients.

Outlook has problems with sending email
by Kenneth Simpson 27 Oct '04

27 Oct '04

Hi - I'm having problems with Stunnel 4.05 and Outlook - but not with Mozilla/Thunderbird. Unfortantely, most of our users use Outlook from Office 2000 and Office XP. The problem is Outlook can't send email when using SIMAP/SSMTP. If the remote users set their SMTP server to be their ISP, then Outlook doesn't have a problem. It suggests a sendmail issue except Mozilla/Thunderbird work fine. How do most people configure stunnel for Outlook? We're behind a screening router and port 587 - the so-called sendmail "submission" port - is currently closed. All ICMP is administratively disabled for this host at the router. But sendmail on this particular host is configured for port 587 behind the firewall. Is there a need to configure stunnel for port 587 too? We're using OpenSSL 0.9.7d Sendmail 8.12.10 Stunnel 4.0.5 SPARC Solaris 5.8 Enclosed is the stunnel.conf file. Under version 3.x roughly year ago things appeared to be working correctly - but we've upgraded both sendmail and SSL since then - and our users where migrating from Outlook Express to Outlook. Any ideas? I've added the options options = DONT_INSERT_EMPTY_FRAGMENTS TIMEOUTbusy = 300 TIMEOUTclose = 60 TIMEOUTidle = 43200 but no help. Any help would greatly appreciated! -- Ken

I have a problem using stunnel v 4.05 under Linux with kernel 2.4.27. My target is using two PC connected via serial port with trafic crypted. I have achieved this schema: +-------+ +-------+ | | | | | PC1 |------------rs232---------| PC2 | | |10.0.0.1 10.0.0.2| | | | | | +-------+ +-------+ I have started pppd in raw mode in PC1 and PC2 and i have verified (with ping)that the link is OK for trafic without criptyng. Below i have tried to "mount" a tunnel cripted between PC1 and PC2 but stunnel server side return an error in openpty function.
