[stunnel-users] SSL Handshake problems

[markzero at logik.ath.cx]

I have a tunnel that forwards connections from syslog-ng on
localhost to my loghost. Or rather, I don't.

In the stunnel logs, I repeatedly get:

2004.08.16 21:28:30 LOG5[23452:1006768128]: syslogngs connected from
 127.0.0.1:32479

2004.08.16 21:30:01 LOG7[23452:1006763008]: syslogngs finished (0 left)

..yet connecting using:

$ openssl s_client -connect localhost:5515

successfully connects to my loghost and prints the certificate details.

Why on earth will s_client connect and not syslog-ng?

Specific details:

192.168.1.6
syslog-ng -> localhost:5515
                   |
stunnel <----------|
   |
stunnel ----------> loghost:5514

loghost:
192.168.1.7
(hosts) ---> stunnel (192.168.1.7:5514) 
                |
syslog-ng (localhost:5515)

I have now been trying to implement encrypted logging for a record time
of three months now and so far every attempt has failed in some way or
another. Can somebody please put an end to this adminstrative misery?

(more verbose program output on request)
