Hello,stunnel-users I have two BCM5820 SSL accelerator card in one Freebsd 7.1 host. But when I plug in two ssl accel card and make stress test by Web Application Stress Tool , I get same banchmark ,about 70reqs/s , 50% cpu usage, as one ssl accel card in box. On another word, it seems only one accle card is working another one is idle. Is there someone has simialer problem as me? How to make the another card work? #pciconf -lv ubsec0@pci0:2:3:0: class=0x0b4000 card=0x001014e4 chip=0x582014e4 rev=0x10 hdr=0x00 vendor = 'Broadcom Corporation' device = 'BCM 5820 Crypto Accelerator' class = processor ubsec1@pci0:2:4:0: class=0x0b4000 card=0x001014e4 chip=0x582014e4 rev=0x10 hdr=0x00 vendor = 'Broadcom Corporation' device = 'BCM 5820 Crypto Accelerator' class = processor Stunnel Version 4.26 # make -D WITH_STUNNEL_SSL_ENGINE install clean Openssl Version 0.9.8e CPU P4 1.6A MEM 512M [root@proxy /usr/ports/security/stunnel]# stunnel -version stunnel 4.26 on i386-portbld-freebsd7.1 with OpenSSL 0.9.8e 23 Feb 2007 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /var/tmp/run/stunnel/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = AES:CAMELLIA:ALL:!ADH:+RC4:@STRENGTH key = /usr/local/etc/stunnel/stunnel.pem session = 300 seconds stack = 65536 bytes sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none [root@proxy /usr/ports/security/]# openssl version OpenSSL 0.9.8e 23 Feb 2007 BTW:MY SITE IS ALSO BOMBED BY MANY SPAM MAIL EVERYDAY, BUT NOT ALL MAILS FROM CHINESE IS SPAM, ACTUALLY USA IS THE SECOND SPAM SOURCE COUNTURY.

Feature request: set environment variable for inetd-type program
by Michael Renner 27 Jan '09

27 Jan '09

Moin, I am not a programmer, I am a writer and user, so I have to ask kindly for a additional stunnel feature I need the ability to push some information from the stunnel client side to the server side. To be more concrete: a self written script that is called by stunnels 'exec' statement need some settings, e.g. username and password. My idea is to configure this in the client side stunnel.conf and pass this as a environment variable to this script. There is no chance to pack these stings in a client certificate, because everybody who is able to handle snoop/tcpdump will be able to read this. I imagine a configuration like this: client stunnel.conf [foo] accept = 127.0.0.1:1234 connect = 192.0.20.0:443 env = "SUSER=renner" env = "SPASS=geheim" server stunnel.conf [foo] accept = 192.0.20.0:443 exec = /opt/foo/script.sh env = yes My question to the developers: do you think this is a helpful feature, also for others?

Use stunnel through firewall for home Web server?
by Bill Eldridge 25 Jan '09

25 Jan '09

I was interested in whether there's a simple way to have stunnel redirect traffic from a public Web browser/port to my home Web browser behind my DSL firewall (no ports opened/forwarded for incoming connections on the router, only outgoing-initiated) I scanned old posts but didn't find anything that quite fit - references are usually for people who want to get out from behind a firewall, not publish sites publicly from behind (i.e. externally initiated clicks)

Compilation problem

Hi everyone I try to compile stunnel, but it fails. Actually, it tells me about a parse error inside signal.h, and i think it's a falsePositive. The configure works great and nothing look strange inside the configure.log. I also tried to googled those errors, but didn't find any clues.

0x09 bytes in stunnel-4.26/src/Makefile.am
by Andrew Schulman 14 Jan '09

14 Jan '09

For some strange reason, there are five hex 09 bytes in stunnel-4.26/src/Makefile.am. This broke my Cygwin build: I remove the Windows-only stuff from this file for Cygwin, and diff captured the 0x09 characters that got removed, but then when I later tried to apply the patch, patch choked on them. It seems that each of these bytes should really be 0x0A. Strange. Andrew.
