Hi, I have installed stunnel-4.05 along with openssl-0.9.7d. I am not able to run it in either daemon or client mode. I read through the stunnel.org webpage but could find any help. when i run /usr/local/sbin/stunnel -d 7898 -r 631 i get the following output. 2004.09.24 15:10:47 LOG3[4752:1073866848]: -d: No such file or directory (2) Syntax: stunnel [filename] | -fd [n] | -help | -version | -sockets filename - use specified config file instead of /usr/local/etc/stunnel/stunnel.conf -fd n - read the config file from specified file descriptor -help - get config file help -version - display version and defaults -sockets - display default socket options I have copied the sampel config file as /usr/local/etc/stunnel/stunnel.conf. what should i do to avoid this? Is there any good document avalibel explaing step by step installation and configuration of stunnel? Thank you, -Riyaz

stunnel: command not found
by Robin Martin 24 Sep '04

24 Sep '04

Hi Guys, I am trying to install stunnel-4.05 on Mac 10.2.8. I am following this http://www.stepwise.com/Articles/Workbench/eart.4.0.html article. I am up to Step 8: Testing your setup. The article is old, but I am aware that stunnel 4.* requires a configuration file rather than command line inputs. My config file is [imapd] accept = 993 exec = /usr/local/libexec/imapd execargs = imaps My problem is, when I run (taken from the article) sudo stunnel -c -f -r localhost:993 I get the following, stunnel: command not found Can I use command line arguments here? It seems to be a very non-specific error. While hunting around for an answer I read somewhere else that stunnel likes to die silently? So perhaps I am doing something wrong but getting a vague error message? Is there a log file that I can look at? Thank you for any help, it is appreciated and I hope I've provided sufficient information. Best Regards, Robin _________________________________________________________________ Find love today with ninemsn personals. Click here: http://ninemsn.match.com?referrer=hotmailtagline

rsync over stunnel 4
by Steven Timm 23 Sep '04

There's an example of rsync over stunnel at http://www.stunnel.org/examples/rsync_mike.html but it appears to be using stunnel 3 syntax. Has anyone successfully made this work using stunnel 4? right now /etc/stunnel.conf is same on client and server, has [rsync] accept = 2222 connect = 873 Steve Timm ------------------------------------------------------------------ Steven C.

Pass phrase dialog
by John Bradley 18 Sep '04

18 Sep '04

When I start stunnel 4.05, I am presented with a dialog that requests that I enter a pass phrase in order to access our private key. Is there anyway to bypass this dialog. I would like to add the pass phrase to the config file, so that the dialog isn't presented. Security isn't an issue. Our config file will be in a secure location. Otherwise, our operations people are going the have to know the pass phrase to start stunnel. Thanks for your help.

unclosed connection issue
by Ken G 15 Sep '04

15 Sep '04

I'm running stunnel 3.xx with thttpd (an embedded http server) on a small embedded machine on a pci card running linux. Establishing ssh, ftp, and http connections and using OpenSSL has all worked fine since they've been installed. I've been experiencing a strange issue. It seems that stunnel fails (somehow) to inform https clients that the connection has been closed. The sequence of events that I'm observing goes like this: T+0.0s: https client initiates request on port 443 (https). T+0.1s: stunnel establishes connection with thttpd on port 80. T+0.4s: thttpd finishes and dies, closing connection with stunnel. T+0.5s: stunnel finishes sending thttpd's output to its client, and then stops, believing that it has finished that connection. If forked, this copy of stunnel dies. The client (internet explorer, firefox, mozilla... doesn't matter) still believes that the connection is active, and waits for additional data. T+10.5s: Roughly 10 seconds later the client decides that the server timed out and displays what has been sent so far, which is the entire page. The only visible symptom is that small webpages seem to take 10 seconds to load. The visible symptom, then, is that webpages below a certain size (where that size is determined by the browser's willingness to refresh its view as data is being sent) take about 10 seconds to load. Is it possible that this behavior is due to stunnel? _______________________________ Do you Yahoo!? Express yourself with Y! Messenger! Free. Download now. http://messenger.yahoo.com

Wish: Option verify service-dependent
by Hans Werner Strube 13 Sep '04

13 Sep '04

With stunnel-4.x, it would be greatly desirable to make the option "verify" (and possibly the related certs) in stunnel.conf service-dependent rather than global. I have not looked at the code sufficiently to determine whether and how this could be possible.
