stunnel and loading keys from hw devices
by Victor Wagner 20 Aug '10

20 Aug '10

Hello, all I've tried to use stunnel with keys on the hardware device, supported by OpenSSL engine and encountered some minor problems: 1. Under Unix systems stunnel doesn't provide UI_METHOD for ENGINE_load_private_key. It passes NULL there and engine complains that no user interface provided. On Unix in many cases default UI_METHOD provided by OpenSSL would do So, replacing line 302 in the ctx.c (line number are given for release 4.33) from uim=NULL ; to uim=UI_OpenSSL(); would significanly improve stunnel functionality. 2. OpenSSL UI objects have two methods to pass arbitraty pointers along 1. generic ex_data based macros UI_set_app_data/UI_get_app_data 2. UI-specific UI_add_user_data/UI_get0_user_data Unfortunately app-specific pointer is set inside engine and retrieved inside a callback, which belongs to application. So author of an engine and author of an application should somehow agree on which metod to use. All engines shipped with OpenSSL (ones which do provide load_private_key method) use UI_add_user_data to pass data to the callback. stunnel's pin_cb (for Win32 version of stunnel in the gui.c) uses UI_get_app_data to retrieve ui_data. I wonder what engine was used when this code was developed and debugged. And it does no check if any meaningful pointer is obtained. I suggest to add following code after line 602 in gui.c: /* if set_app_Data haven't-return anything */ if (!ui_data) ui_data=UI_get0_user_data(ui); /* if still no avail */ if (!ui_data) { s_log(LOG_ERR,"Engine haven't passed our callback data to callback. Sorry!"); return 0; } Or instead of complaining we can use some structure, local to function pin_cb as fallback UI_DATA - just as password buffer, and check if ui_data->section is not NULL before reading ui_data->section->key in the pass_proc (line 543 of gui.c) Thus it would work even with really broken engines which do not pass userdata from ENGINE_load_private_key to UI callbacks at all. ----- End forwarded message -----

stunnel and mod_gnutls
by Yclept Nemo 15 Aug '10

I run a mod_gnutls (0.5.5)<->apache (2.2.8) webserver which behaves perfectly normally outside of stunnel: GnuTLSEnable on GnuTLSPriorities SECURE256 GnuTLSExportCertificates on .. When a connection is closed and apache signals the mod_gnutls process to quit, the log records: GnuTLS: Handshake Failed (-8) 'A record packet with illegal version was received.' Invalid method in request NS * HTTP/1.0 ::1 - - [15/Aug/2010:03:31:26 -0400] "NS * HTTP/1.0" 501 512 "-" "Apache/2.2.8 (Ubuntu) ... (internal dummy connection)" This lets me easily identify apache2 process turnovers However, when I connect to this server through stunnel, I receive random dropouts. For example, if I were to upload 200 test files to this server, on average 15 transfers would fail. Stunnel logs (excerpt): 2010.08.15 04:11:25 LOG5[29287:3074030448]: Connection reset: 94 bytes sent to SSL, 523 bytes sent to socket 2010.08.15 04:12:21 LOG5[29287:3074448240]: Connection reset: 94 bytes sent to SSL, 523 bytes sent to socket 2010.08.15 04:12:34 LOG5[29287:3074030448]: Connection reset: 94 bytes sent to SSL, 523 bytes sent to socket And my apache2 logs are flooded with: Invalid method in request \x16\x03\x01 # ... over and over and over ...

help - SSL bandwidth overhead with using different ciphers
by Slim Ben Mahmoud 30 Jul '10

30 Jul '10

Dear SSL experts, In order to assess the performances of an adaptive security algorithm using SSL, I need to measure the network overhead induced by the establishment of SSL tunnels. The experiment aims to measure the bandwidth consumptions (or throughputs) when SSL tunnels are established using the different ciphers implemented in Stunnel (AES256-SHA or RC4-SHA for instance). Do you think that I have to expect a different throughput when I use different ciphers for every tunnels or the overhead is the pretty much the same? In fact, the first results show no difference between the throughputs no matter the cipher I use. I know that SSL overhead is traditionally measured in delay or latency because of the handshake phase (the encryption process time is negligible on the new CPUs) but this is not what i want to show. I hope that my request is enough clear, let me know if it is not the case. Best regards. --Slim

Hi All I want to build a proxy server, which acts as man in the middle proxy. The main intention of application is to do content filtering, whether it is an http or https request. I want to block some specified URL. Can anybody tell me what is the best approach of doing this Thanks, Raj Rajmohan SK

Reason why I am asking you because when I log off the server then stunnel's process stopped running but I want it keep running after logoff.

problem with "verify=0"
by wujot＠home.pl 07 Jul '10

07 Jul '10

Hello everybody, The basic SSL negotiation requires the exchange of nine SSL messages. If client authentication is required, server can send additional message "certificate request". But this message is optional. I'm using stunnel ver. 4.27 for Win and 4.28 for Linux. In both cases stunnel, working as server, is sending "certificate request" message to the client, regardless of "verify" state, even with "verify=0". When "verify=0", server doesn't care about client's certificate. So, what for server sends this message? The part of my configuration and log is bellow: [test] accept = 60000 connect = 192.168.3.15:4679 client = no ;verify = 0 verify = none ciphers=DES-CBC3-SHA session = 3600 2010.07.07 12:53:35 LOG7[2412:4280]: SSL state (accept): before/accept initialization 2010.07.07 12:53:35 LOG7[2412:4280]: SSL state (accept): SSLv3 read client hello A 2010.07.07 12:53:35 LOG7[2412:4280]: SSL state (accept): SSLv3 write server hello A 2010.07.07 12:53:35 LOG7[2412:4280]: SSL state (accept): SSLv3 write certificate A 2010.07.07 12:53:35 LOG7[2412:4280]: SSL state (accept): SSLv3 write certificate request A <-------------???!!! 2010.07.07 12:53:35 LOG7[2412:4280]: SSL state (accept): SSLv3 flush data 2010.07.07 12:53:42 LOG6[2412:4280]: VERIFY IGNORE: depth=1, /C= .............. 2010.07.07 12:53:42 LOG5[2412:4280]: CRL: verification passed 2010.07.07 12:53:42 LOG5[2412:4280]: VERIFY OK: depth=1, /C= .......... 2010.07.07 12:53:42 LOG6[2412:4280]: VERIFY IGNORE: depth=0, /C= ................ 2010.07.07 12:53:42 LOG5[2412:4280]: CRL: verification passed 2010.07.07 12:53:42 LOG5[2412:4280]: VERIFY OK: depth=0, /C= .......................... 2010.07.07 12:53:42 LOG7[2412:4280]: SSL state (accept): SSLv3 read client certificate A 2010.07.07 12:53:42 LOG7[2412:4280]: SSL state (accept): SSLv3 read client key exchange a 2010.07.07 12:53:42 LOG7[2412:4280]: SSL state (accept): SSLv3 read certificate verify A 2010.07.07 12:53:42 LOG7[2412:4280]: SSL state (accept): SSLv3 read finished A 2010.07.07 12:53:42 LOG7[2412:4280]: SSL state (accept): SSLv3 write change cipher spec A 2010.07.07 12:53:42 LOG7[2412:4280]: SSL state (accept): SSLv3 write finished A So, my question is: how to remove "certificate request" message from stunnel-as-server negotiation?

Re: [stunnel-users] telnetd and tcp_wrappers

2 guys did help me and still no luck... Anyone who tried this: [tssl] accept = 992 exec = /usr/sbin/telnetd Let me know... Reason why I am asking you because when I log off the server then stunnel's process stopped running but I want it keep running after logoff. Before I changed 'exec = /usr/sbin/telnetd', it was 'connect = 23' and the stunnel's process ran great and never stop running... Strange. I really need your help. Thanks. --------------- Tom Spence ABIDES SYSTEM SUPPORT 844th CS/SCOX

Hi Again, I tried: [tssl] accept = 992 exec = /usr/sbin/telnetd It works. When I log into the server with no problem. When I am ready to log off then the process stopped running??? How can it stays running in process (/usr/local/bin/stunnel)? Thanks. Tom -----Original Message----- From: Spence, Thomas Civ 844 CS/SCOX Sent: Thursday, July 01, 2010 11:53 AM To: 'stunnel-users(a)mirt.net' Subject: telnetd and tcp_wrappers Hi all.. They requested us to turn off the telnetd from inetd.conf and not allowing to use tcp_wrappers... We are still using stunnel 4.33... We can't connect our server from PC with PowerTerm WebConnect because telnetd is off. Is there any way for all users to connect the server by using PowerTerm WebConnect? stunnel.conf: [tssl] accept = 992 connect = 23 (can't use telnet port) I know I can't use "connect = 22" because it doesn't work.
