Connection Problem on Vista
by Earl Stenlund 08 Mar '08

08 Mar '08

I setup stunnel this afternoon to work with Newshosting. It was working fine but now I cannot connect using my desktop running Vista. I receive this message: SSL_connect: 14094406: error:14094406:SSL routines:SSL3_READ_BYTES:sslv3 alert decompression failure Stunnel connects fine on my laptop which is also running Vista. Help, Earl Stenlund

Username authentication
by Joe Kemp 07 Mar '08

07 Mar '08

I want to try to use stunnel as a "simple" client vpn. It solves all of my encryption issues but I would like to verify a username/password before it lets the traffic through. I didn't see any patches or hacks out there that did this. Has this been attempted before or am I on my own. I would also be interested in other solutions based on openssl that are not network device level VPNs clients. Already using client side certificates and I know that is the normal SSL authentication mechanism.... Thanks. -Joe

Send delay?
by Colin E 04 Mar '08

04 Mar '08

Please can you help a hardware engineer, who almost understands what he's doing. I'm using sTunnel 4.21 on a Windows 2000 machine, to provide a TCP program with SSL. This works very well. However the application is very time critical and must finish sending block of XML as quickly as possible. I suspect there is a delay in either sTunnel or openSSL, while it waits to see if there are any more characters before sending a packet. Is this correct? If it is, is there a work round. -- View this message in context: http://www.nabble.com/Send-delay--tp15826043p15826043.html Sent from the Stunnel - Users mailing list archive at Nabble.com.

Hello to all! I'm trying to set up Stunnel for the first time. I hope to use it with HFS. I followed directions found on HFS website and ran into a problem creating a pem file. Could someone direct me to information about installing Stunnel? Or help me directly by sharing with me how to install Stunnel? I sincerely appreciate your help!!! Rod

Hallo, I have found 2 Bugs. 1. In Version 4.21: No Taskbar Icon is displayed when the service starts. Although the taskbar ist set in config file (taskbar = yes). 2. In probably all Versions (I have testet 4.18, 4.20 and 4.21) If i started the service over Start -> Programm Files -> stunnel -> Service Start (stunnel -start) no log files are written. If i start the service over services.msc from Windows or "sc start stunnel" log files are written. The icon log displayed the following message in version 4.18 and 4.20 2007.11.09 09:41:03 LOG3[2396:2400]: stunnel.log: Broken pipe (32) 2007.11.09 09:41:03 LOG3[2396:2400]: Unable to open output file: stunnel.log Best Regards Jan

Stunnel currently logs times in the format hh:mm:ss. Is there a way to get a more exact time, such as UTC or down to the millisecond? Edward Blake

VNC, STUNNEL & HTTPTUNNEL ----- (((VNC)SSL)HTTP)
by sean bhola 25 Feb '08

25 Feb '08

I need to connect to my PC at work from home. The firewall at work has only ports 80 (http) and 443 (https) open, I also think there is a proxy. I was wondering which scenario would work. 1: To encapsulate vnc traffic within ssl using stunnel and pass it though port 443, OR 2: To encapsulate vnc traffic within ssl using stunnel, then encapsulate that within http using httptunnel and pass through port 80 OR 3: To encapsulate vnc traffic within http, then encapsulate that within ssl using stunnel and pass through port 443 I read this article http://www.securityfocus.com/infocus/1677 but still had the concerns above. Help would be much appreciated. Thanks. Sean

running SWAT through stunnel and uid/gid question
by Wayne Sherman 24 Feb '08

24 Feb '08

(using STunnel 4.21 on gentoo) I can successfully run the samba SWAT tool through stunnel with these settings: [swat] exec = /usr/sbin/swat execargs = swat accept = 901 But, I have discovered that in order to successfully log-in to swat, I have to comment these lines in the global section of stunnel.conf: #setuid = stunnel #setgid = stunnel Is there a way to specify the UID/GID per service (like the xinetd service level option "user") instead of globally? Thanks, Wayne
