Will stunnel service need to be restarted after the configuration changes.
by Zhijiang Lu 15 Aug '07

15 Aug '07

Hi All, After some changes being made to the stunnel configuration file, do I need to restart the stunnel service to pick up the changes? I would think it is desirable to load up the new configurations, and make runtime changes correspondingly. Restarting stunnel will disrupt the currently running sessions. Thanks, -Mark

by atsushi kataoka 12 Aug '07

12 Aug '07

Hi, I have to secure one of my proprietary remote connection server running on windows XP . One option is to secure using the stunnel.Other options are writing some drivers for windows. Presently we are evaluating which option is better whether to opt for application level - stunnel or go for driver - some network filter driver. Can somebody tell me what will be advantages of following application level approach. One more point what is the impact on the performance of using stunnel. Regards.

Stunnel writing strange timestamps into my logs
by Van 10 Aug '07

10 Aug '07

I was looking through /var/log/messages for another reason and I notice this (representitive log snippet below) It's 10:50 am and while automount is writing messages that jibe with the correct time (see line 5 for example. This part of my log is from about 90 min ago), stunnel seems to be 4 hours ahead, labelling things as happening at about 1pm while everything else is happening about 9am. Where is stunnel getting it's time from? And why a separate source? How can I correct this? - Van Aug 10 13:13:01 <myserver> stunnel: LOG5[29760:3086109600]: pop3s connected remote server from 127.0.0.1:54923 Aug 10 13:13:03 <myserver> stunnel: LOG5[29760:3086109600]: Connection closed: 211 bytes sent to SSL, 56 bytes sent to socket Aug 10 13:13:34 <myserver> stunnel: LOG5[29760:3086109600]: imaps accepted connection from XX.XX.61.109:1409 Aug 10 13:13:34 <myserver> stunnel: LOG5[29760:3086109600]: imaps connected remote server from 127.0.0.1:54927 Aug 10 09:14:13 <myserver> automount[30173]: >> mount: mount to NFS server 'mgm' failed: System Error: Connection timed out.

Tunneling though an Http proxy
by Honka 10 Aug '07

10 Aug '07

Hi there, i'm trying to set up stunnel on my laptop which I use at work, and i'm trying to tunnel to my home pc for remote desktop. The only open ports on the work network are 8080, 80 and 443. So I have setup the tunnel to port 8080 onto my home pc and had it working across the network at home. (via internal and external ip's) however it isn't working here. I am assuming because we have an http proxy which requires authentication. So i'm wondering, how can I make stunnel use and authenticate with this proxy so that it will work? Cheers Honka

Stunnel message about SSL_shutdown/SSL_get_error
by Lachance, Mario 03 Aug '07

03 Aug '07

Hi, I have been using openssl_0.9.7g and stunnel_4.10 on Solaris 9 without problem for 2 years in a production environment. I want to upgrade to openssl_0.9.8e and stunnel_4.20 on solaris 10. I have done some test on a development system and I have seen a new message in stunnel log file. Old message with openssl_0.9.7g and stunnel_4.10 on Solaris 9 was : Aug 3 14:51:58 solario stunnel[345]: [ID 702911 local6.notice] Too many retries on SSL shutdown New message with openssl_0.9.8e and stunnel_4.20 on solaris 10 is : Aug 3 14:42:30 daprxuu stunnel: [ID 821868 local6.error] LOG3[20957:4]: SSL_shutdown/SSL_get_error returned 6 I don't know if this new message has replaced the old one I was getting. Can someone tell me what is behind this message "_shutdown/SSL_get_error returned 6"? Please note that I am able to transfer message with both system (stunnel 4.10 and stunnel 4.20) from a windows client without any apparent problem.
