Can't get NTLM authentication to work with proxy connect.
by Rudy Ghani 01 Apr '09

01 Apr '09

Hi there, My stunnel client is on an Active Directory-authenticated XP workstation, which needs to connect via a web proxy that authenticates using NTLM. I populated my login details in protocolUsername and protocolPassword, but the connection just dies when it reaches the proxy server. Looking at the log, I get the following:- 2009.04.01 08:20:39 LOG6[2140:2892]: SSL connected: new session negotiated 2009.04.01 08:20:39 LOG6[2140:2892]: Negotiated ciphers: AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 2009.04.01 15:34:09 LOG7[2140:2708]: ssh3 accepted FD=356 from 127.0.0.1:1026 2009.04.01 15:34:09 LOG7[2140:2708]: Creating a new thread 2009.04.01 15:34:09 LOG7[2140:2708]: New thread created 2009.04.01 15:34:09 LOG7[2140:3896]: ssh3 started 2009.04.01 15:34:09 LOG7[2140:3896]: FD 356 in non-blocking mode 2009.04.01 15:34:09 LOG7[2140:3896]: TCP_NODELAY option set on local socket 2009.04.01 15:34:09 LOG5[2140:3896]: ssh3 accepted connection from 127.0.0.1:1026 2009.04.01 15:34:09 LOG7[2140:3896]: FD 472 in non-blocking mode 2009.04.01 15:34:09 LOG7[2140:3896]: ssh3 connecting 129.32.20.14:8080 2009.04.01 15:34:09 LOG7[2140:3896]: connect_wait: waiting 10 seconds 2009.04.01 15:34:09 LOG7[2140:3896]: connect_wait: connected 2009.04.01 15:34:09 LOG5[2140:3896]: ssh3 connected remote server from 130.32.82.203:1027 2009.04.01 15:34:09 LOG7[2140:3896]: Remote FD=472 initialized 2009.04.01 15:34:09 LOG7[2140:3896]: TCP_NODELAY option set on remote socket 2009.04.01 15:34:09 LOG5[2140:3896]: Negotiations for connect (client side) started 2009.04.01 15:34:09 LOG7[2140:3896]: -> CONNECT xxxx.ath.cx:443 HTTP/1.1 2009.04.01 15:34:09 LOG7[2140:3896]: -> Host: xxxx.ath.cx:443 2009.04.01 15:34:09 LOG7[2140:3896]: -> Proxy-Connection: keep-alive 2009.04.01 15:34:09 LOG7[2140:3896]: -> Proxy-Authorization: NTLM TlRMTVNTUAABAAAAAgIAAA== 2009.04.01 15:34:09 LOG7[2140:3896]: -> 2009.04.01 15:34:09 LOG3[2140:3896]: Unexpected socket close (fdgetline) 2009.04.01 15:34:09 LOG5[2140:3896]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2009.04.01 15:34:09 LOG7[2140:3896]: ssh3 finished (1 left) If I decode the NTLM auth string, I only get the NTLMSSP header, which seems to be incomplete. If I recall correctly the domain and workstation info should be passed on as well. So question is, how do I get this to work? Is there any specific format that I need to use when using the protocol* settings for NTLM? Thanks and regards.

SSL CTX use RSA Private Key error
by G K 27 Mar '09

27 Mar '09

Hello all. I am trying to set up stunnel for use on my machine. I shouldn't have a problem with iptables. But I do run tor/privoxy on a regular basis if that matters. I also have set up my gpg keys too. The following is the error I get. I did do some Googling but I'm not quite understanding what I'm looking for to change or modify. I know the error is the SSL CTX RSA private key.

stunnel 4.26 MS SQL connetion - works on Vista, not on XP
by zervakos 25 Mar '09

25 Mar '09

Greetings, I was wondering if anyone's come across anything like this. I want to encrypt connections for MS SQL Server 2008 Express from a Windows XP client to a Windows 2003 Server. Following these instructions: http://www.securityfocus.com/infocus/1677 I was able to configure encrypted connections by pointing SQL Server Management Studio to 127.0.0.1 on _either_ XP or Vista and then that gets tunneled over to the Windows 2003 Server running SQL Server 2008 Express. I can browse the database tables, etc. Now the problem. I have users that make use of a thin client that connects directly to the SQL Server. It has one config file that I've pointed to 127.0.0.1. When I run this thin client on Vista, it works great, however, when running it on XP, stunnel tries to connect, but then gives up after several attempts. Here's what I see in the server log before connecting: 2009.03.23 12:26:59 LOG7[284564:274684]: RAND_status claims sufficient entropy for the PRNG 2009.03.23 12:26:59 LOG7[284564:274684]: PRNG seeded

settings of the thin client to work under ealier versions of Windows, this didn't help - regenerated certificates, no good - tried connecting without certificates, still no good I still haven't tried earlier versions of stunnel, but I figured I'd just check and see if may anyone's run across something like this before. From what I can tell, the combination of XP, the thin client and stunnel does not work. The thin client does work on XP when I do not use stunnel, but I need to have the connection encrypted. Any help greatly appreciated, thanks -- View this message in context: http://www.nabble.com/stunnel-4.26-MS-SQL-connetion---works-on-Vista%2C-not… Sent from the Stunnel - Users mailing list archive at Nabble.com.

Re: [stunnel-users] Using stunnel in a box having http client and http server.

So, my understanding is that I will need one stunnel for each remote web server that my http client is going to connnect to. For example if my http client want to connect to 3 remote web servers.

Who is going to connect to your http "client" ? if it is your local browser (which seems the goal of the configuration), then you can configure the client with "accept=81" and then type in your browser's address bar "https://localhost:/81" -- Christophe Nanteuil DISCLAIMER: This e-mail and any attachments to it may contain confidential and proprietary material and is solely for the use of the intended recipient.

Re: [stunnel-users] Using stunnel in a box having http client and http server.
by Joe Lau 20 Mar '09

20 Mar '09

Hello, I am new to this list. I am planning to use stunnel on my box which has a http client and http server running on it. I will need two stunnel instances, one for the http client and one for the http server respectively. For my http client, my stunnel config file looks like this: client=yes accept=80 connect=remote_web_server:443 For my http server, my stunnel config file looks like this: client=no accept=443 The problem I am facing is now I have two programs (i.e. 1) stunnel for http client and 2) http server) listening to the same port 80. How do I resolve this conflict? Thank you very much for the help.

Is this possible? Stunnel FIPS mode with rdesktop to secured Microsoft terminal server
by David W Blaine 16 Mar '09

16 Mar '09

Hi list, I was wondering if this solution is possible? Linux Linux Windows Server 2003 rdesktop ----> Stunnel client ------> Terminal Server no enc FIPS mode FIPS mode I know there is doco's about how to setup a Stunnel using client and server setups on either side but Windows admins here are unlikely to install Stunnel on their side. They have enabled FIPS mode on their Windows servers and disconnected all the Linux/UNIX admins from their Terminal Server. So I was wondering if I could get away with a client only solution? Dave

persistent SSL connection
by Dorai Ashok 16 Mar '09

16 Mar '09

Hi all, I was able to setup stunnel between two hosts successfully but the only problem I am facing is that, the SSL connection between the two hosts is not persistent. For every connection I make to the stunnel client, a new SSL connection is established by the stunnel client to the stunnel server. Is there a configuration variable in stunnel which can make the SSL connection between stunnel client and server persistent ? Thanks, -Dorai.

Unless, of course, you are trying to communicate with a third-party product that speaks SSL - if either the client or the server is not under your control, there's no way to make them use multiplexed SSH connections instead of SSL :) But if it's just stunnel on both sides, then yes, SSH tunneling may be a better choice for multiplexing, although it has its own problems - most often related to connection keepalive, especially if there is some kind of firewalling gateway on the path.

Re: [stunnel-users] Configuring stunnel to use p12 and p7b in client mode
by Eduard Witteveen 14 Mar '09

14 Mar '09

Pierre and List, Thanks for the answer. Maybe i wasn't clear enough in my question: 1 - I have a p12 and p7b file, which work in firefox and iexplore. 2 - I want to setup a tunnel, so the encryption is done by stunnel and not by the browser(so i can 'talk' normal http for soap) Removing the password sounds like a good idea, so i started with this. However, somehow my openssl doesnt know the command pkey.

Can stunnel do this?
by Miguel Beccari 13 Mar '09

13 Mar '09

I tried this configuration: client = yes debug = debug cert =/Users/etc/stunnel/stunnel.pem [imaps] accept = localhost:143 delay = yes connect = remote:993 and it worked! But if I change "accept = localhost:143" to "accept = localhost:993" it does not work. I need a imaps proxy. Logs does not say anything interesting (SSL accepted: new session negotiated) Thank you all, Miguel
