Stunnel and streaming audio
by grimholtz＠mailbolt.com 19 Oct '04

19 Oct '04

Hi, I'm using stunnel 4.05 on Windows 2000 for both client and server. I have VNC working just fine over port 443. Now I want to stream audio from the server to the client over port 21 with stunnel and any streaming audio server. I can't get this to work. I'm currently using Windows Media Encoder for streaming because it is simple and free, but I don't mind switching to SHOUTcast or something else. This is the stunnel server configuration: CAfile = CAcert.pem CApath = certificates cert = server.pem client = no verify = 3 [vnc] accept = 443 connect = 127.0.0.1:15351 [audiostream] accept = 21 connect = 127.0.0.1:80 On the client-side, I have this configuration: CAfile = CAcert.pem CApath = certificates cert = client.pem client = yes verify = 3 [vnc] accept = 127.0.0.1:15351 connect = someurl.com:443 [audiostream] accept = 127.0.0.1:80 connect = someurl.com:21 VNC works fine but streaming audio does not. It doesn't matter if I change port 21 to something else; I get the same error. The output on the server-side stunnel console is: 2004.10.18 13:16:02 LOG5[2036:1732]: audiostream connected from xxx.xxx.xxx.xxx:59090 The output on the client-side stunnel console is: 2004.10.18 13:21:07 LOG5[1088:1300]: audiostream connected from 127.0.0.1:1467 2004.10.18 13:21:07 LOG3[1088:1300]: SSL_connect: Peer suddenly disconnected stunnel -version on the server-side displays this info: stunnel 4.05 on x86-pc-mingw32-gnu WIN32 with OpenSSL 0.9.7d 17 Mar 2004 Global options cert = stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH debug = 5 key = stunnel.pem RNDbytes = 64 RNDoverwrite = yes service = stunnel session = 300 seconds taskbar = yes verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTidle = 43200 seconds 2004.10.18 20:47:05 LOG3[1316:2092]: Server is down openssl version on the server-side displays this info: OpenSSL 0.9.7d 17 Mar 2004 Anyone have ideas?

Client certificates still valid after removal with verify = 3
by Michael Brown 18 Oct '04

18 Oct '04

I'm having a problem with my stunnel 4.05 setup: We are using a setup where each client that connects has to have a valid certificate present on the filesystem (verify = 3). After the client connects once, it seems that the certificate is cached by either the SSL libraries or stunnel: stunnel.conf: <<< cert = /etc/stunnel/servercert.pem CAfile = /usr/share/ssl/CA/cacert.pem CApath = /etc/stunnel/clientdb verify = 3 [https] accept = 443 connect = remote.server.name:443 local = 192.168.0.6 >>> Some output: Oct 15 19:36:34 machine stunnel[14139]: VERIFY OK: depth=1, /C=CA/ST=Ontario/L=Here/O=Us/OU=Bigwigs/CN=CA Cert/emailAddress=certainly(a)here.com Oct 15 19:36:34 fruitfly stunnel[14139]: VERIFY OK: depth=0, /C=CA/ST=Ontario/O=Us/OU=slackers anonymous/CN=Daniel Unceman/emailAddress=dunce(a)here.com ... and the same thing after I remove the hash link in /etc/stunnel/clientdb. But only after I restart does it to the right thing: Oct 15 19:40:24 fruitfly stunnel[15247]: VERIFY OK: depth=1, /C=CA/ST=Ontario/L=Here/O=Us/OU=Bigwigs/CN=CA Cert/emailAddress=certainly(a)here.com Oct 15 19:40:24 fruitfly stunnel[15247]: VERIFY ERROR ONLY MY: no cert for /C=CA/ST=Ontario/O=Us/OU=slackers anonymous/CN=Daniel Unceman/emailAddress=dunce(a)here.com Help!

I am new to the product and encryption as well, but am looking for some unix examples using with an HTTP client and a server to communicate with HTTP/S applications.

Stunnel V4.05 error with rsync
by craig hobbs 12 Oct '04

12 Oct '04

Hello, I am using stunnel v4.05 with rsync v2.6.0 and solaris9 as both my client and server machine. I am running rsync in daemon mode on the server and starting an rsync transfer on the client. I am getting a frequent error where my rsync client process just appears to hang. On the client side I will receive several 'SSL_read returned WANT_: retrying/SSL_write returned WANT_: retrying' messages back-to-back and then finally the message is always 'Socket closed on read'. Some data does get transferred but it appears from the messages that the socket looses its connection, and the the rsync process just hangs until time-out. Currently in no-blocking mode with the following limits: FD_SETSIZE=1024, file ulimit=2147483647 -> 500 clients allowed Is there any stunnel bug or system resource limit that could be the problem ??

connection timeout
by SqM 10 Oct '04

10 Oct '04

Hi! I have an application that itself has the possibility to use a backup server. I.e config of primary and secondary server. I have set up the application to connect to localhost on 2 different ports ( 1000 and 1001 ) and each of the ports are forwarded to a primary and secondary server. When testing this setup i find that if i route packets to the primary server to /dev/null in order for the application to select the secondary server the application seems to be happy since stunnel answers. After aproxx 300 seconds i can see in the log that stunnel gives up and that the application sees this. The appliation then happily selects the secondary server. The question then is if it is possible to make stunnel a little bit faster in giving up.. I.e. perhaps 30 sec instead of 300 sec. I found one setting in the client config that seems to do this but the question is.. Is this the correct way to do it.. I.e. setting "TIMEOUTbusy = 30 seconds" seems to fix my problem but is this the rigth way or is there a better way? /Sqm

Stunnel question
by Rick Cone, Secure Payment Systems 06 Oct '04

06 Oct '04

I use Stunnel as a server that connects locally to a port with an application running (called Mlink). The software on that port will only allow 1 connection on the port at a time, not achieving a (true) socket server environment. Does anyone know of a piece of software (like a load balancer) that would accept connections on a specific port (from Stunnel in this case...), and then round-robin connections (or something thereof) to a set of ports? Thanks, Rick Cone Secure Payment Systems 801 8th St. #150-D Greeley, CO 80631 970-352-9434 (office) 970-352-0122 (fax, call office first) rcone(a)securepaymentsystems.com Note: This electronic message and attachments, if any, contain information which is intended solely for the designated recipients.

stunnel dies on win32 - Try again with out HTML
by Richard Whiffen 05 Oct '04

05 Oct '04

We have a problem where stunnel dies on our Win32 boxes when we attempt load tests: stunnel 4.05 on x86-pc-mingw32-gnu WIN32 with OpenSSL 0.9.7d 17 Mar 2004 Global options cert = stunnel.pem ciphers = ALL:!ADH:+RC4:@STRENGTH debug = 5 key = stunnel.pem RNDbytes = 64 RNDoverwrite = yes service = stunnel session = 300 seconds taskbar = yes verify = none Service-level options TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTidle = 43200 seconds When we had one stunnel.cnf for all services it would crash almost imediately (less than a minute after starting the load). When we created separate processes for each target server it lasts longer, 5 to 10 minutes, but still dies. The frustrating part is we get no indications in the log files of what's going on. It dies in seemingly random spots. The last log entry is never the same and there's nothing in the cmd window that launched it to indicate what happened. The conf is fairly simple: #script test conf cert = \stunnel\ohetestisg1.pem Cafile = \stunnel\css-ca-cert.pem CApath = \stunnel\certs output = \stunnel\stunnel-media.log #verify = 3 client = yes debug = 7 [**mediaserver] accept = 127.0.0.3:80 connect = 10.162.130.26:444 TIMEOUTclose = 0 We're connecting to a Cisco Content Server Switch if that helps. So I'm wondering where to go next. Any ideas on how to troubleshoot this?

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

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
