[stunnel-users] Stunnel and streaming audio

[grimholtz at mailbolt.com]

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:

openssl version on the server-side displays this info:

Anyone have ideas?

Thank you in advance for any advice,
