[stunnel-users] Can not estabilish stunnel

Hi,

I have difficulties setting up a tunnel between two linux box I
administrate. Right now its only in test phase, i would like to make an
stunnel connection to the smpt server at 195.56.52.140. My final goal is
to set up syslog through stunnel, thats why the port name/numbers.


Config file for the server:

cert = /usr/local/etc/stunnel/stunnel.pem
pid = /usr/local/etc/stunnel/stunnel.pid
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
debug = 7
output = /usr/local/etc/stunnel/stunnel.log
[ssyslog]

accept = 195.56.52.140:2514
connect = 10.10.2.1:25

Config file for the client:

cert = /usr/local/etc/stunnel/stunnel.pem
pid = /usr/local/etc/stunnel/stunnel.pid
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
debug = 7
output = /usr/local/etc/stunnel/stunnel.log
client = yes
[ssyslog]
accept = 2514
connect = 195.56.52.140:2514

I get the following messages in the logs after, executing a "telnet
127.0.0.1 2514" command at the client machine (of course, smtp works on
the other side, and i set iptables to allow incomming connections on
2514 dport)
